Introduction
Cyberattacks targeting the energy sector are increasing,
driven by a host of geopolitical and technological factors. A report published
by Sophos in July 2024, and which surveyed 275 cybersecurity and IT leaders
from the energy, oil/gas, and utilities sector across 14 countries, found 67%
of respondents who said their organizations had suffered a ransomware attack in
the last year.
While Sophos’ figure remained steady year-over-year, a
January 2025 report authored
by TrustWave said that ransomware attacks targeting the energy and utilities
sectors increased by 80% in 2024 compared to the previous year. Most of these
breaches have only managed to compromise IT environments, as opposed to more
critical operational technology (OT) networks, but the threat to the latter is
rapidly intensifying.
Moreover, ransomware is just one aspect of the broader
energy-sector threat landscape. This threat intelligence research is a
continuation of our material published last year - "Ransomware Attacks against the Energy Sector on the rise -
Nuclear and Oil & Gas are Major Targets in 2024", highlighting
threat actors targeting energy installations in North America, Asia, and the
European Union, including nuclear facilities and related research entities.
Hacktivism is another prevailing threat targeting
energy firms, with ideologically motivated adversaries linked to Russia and
various Gaza-nexus adversary groups attempting to build credibility by
publicizing alleged compromises of various victims’ OT networks. Most
concerning, nation-state espionage actors linked to China, Iran, and North
Korea have also increasingly been observed targeting the energy sector,
including nuclear facility
personnel.
These cyber-espionage campaigns are primarily driven by
geopolitical considerations, as tensions shaped by the Russo-Ukraine war, the
Gaza conflict, and the U.S.’ “great power struggle” with China are projected
into cyberspace. With hostilities rising, potentially edging toward a third
world war, rival nations are attempting to demonstrate their cyber-military
capabilities by penetrating Western and Western-allied critical infrastructure
networks. Fortunately, these nation-state campaigns have overwhelmingly been
limited to espionage, as opposed to Stuxnet-style attacks intended to cause
harm in the physical realm.
A secondary driver of increasing cyberattacks against energy
targets is technological transformation, marked by cloud adoption, which has
largely mediated the growing convergence of
IT and OT networks. OT-IT convergence across critical infrastructure sectors
has thus made networked industrial Internet of Things (IIoT) appliances and
systems more penetrable to threat actors. Specifically, researchers have
observed that adversaries are using compromised IT environments as staging
points to move
laterally into OT networks.
Compromising OT can be particularly lucrative for ransomware
actors, because this type of attack enables adversaries to physically paralyze
energy production operations, empowering them with the leverage needed to
command higher ransom sums. In cyber-military or cyber-terroristic scenarios,
however, the sabotage of OT systems can be catastrophic for physical
environments and human life.
Another technological trend that has transformed the threat
environment for energy firms is rapidly advancing AI adoption. Not only has AI
lowered the barriers to entry for certain types of attack campaigns, but the
growing integration of AI with energy sector networks has introduced a
maelstrom of new cyber-risk scenarios.
This trend has most notably impacted the
nuclear sector, with Constellation Energy, the largest nuclear energy
conglomerate in North America, announcing in
2022 that they were “looking at AI to decrease our customers’ energy costs and
to optimize the many tasks they perform on a regular basis.” At the same time,
recent announcements from AI and cloud-focused Big Tech firms like Microsoft,
Meta, and Google indicate that they have plans to tap nuclear energy to power their
future data centers.
Beyond the emerging nuclear-AI nexus, the North American
Electric Reliability Corporation (NERC), a non-profit international regulatory
authority that enforces industry standards in the U.S. and Canada, warned last
year that American power grids are becoming increasingly vulnerable to
cyberattacks. According to NERC, the number of susceptible points in electrical
networks is growing by about 60 per day.
A Reuters report on NERC’s warning noted
that “geopolitical conflict, including Russia's invasion of Ukraine and the war
in Gaza, have dramatically increased the number of cyber threats to North
American power grids.” Resecurity’s second report on cyber threats targeting
energy operators will detail recent Dark Web activity, highlighting adversary
claims of successful breaches impacting this critical infrastructure sector.
The report will present findings collected by Resecurity’s
HUNTER threat intelligence unit in order of ransomware-related incidents,
access brokers, hacktivist leaks, and breaches specifically targeting the
nuclear sector.
Ransomware-Nexus Leaks
The most significant energy-sector ransomware attack of the
last year was RansomHub’s breach of Halliburton in August 2024.
Headquartered in Dubai (UAE) and Houston (USA), Halliburton is the world’s
second-largest oil service company and is involved in most of the world’s
fracking operations. According to BleepingComputer, the RansomHub attack
cost Halliburton $35 million in losses “after
the breach caused the company to shut down IT systems and disconnect
customers.”
In April 2025, HUNTER analysts observed an announcement on
the RAMP cybercrime forum indicating that RansomHub has
decided to move to DrangForce’s ransomware-as-a-service (RaaS)
infrastructure.
In February 2025, Resecurity published a report documenting DragonForce’s
recent targeting of Saudi Arabia. The budding partnership between these groups
is an intriguing development in the RaaS ecosystem, particularly given their
strong reputation and popularity among more accomplished ransomware actors and
the recent disbandment of elite threat actor group BlackBasta.
Notably, DragonForce also claimed responsibility
for a December 2024 data breach that impacted Luxembourg-based renewable energy
investment firm Ikav Energy. According to the company’s webpage, “IKAV is an
international asset management group that provides institutional investors with
investment solutions spanning a broad range of infrastructure energy assets,
including solar, concentrated solar power, wind, energy efficiency, geothermal,
thermal power plants and upstream.”
This attack resulted in the compromise of nearly 177 GB of
IKAV data, according to DragonForce’s December shame-blog posting.
In March, Comparitech reported that Ikav “notified 722 people
in Texas and 15 in Massachusetts of the breach, with more victims expected as
more states disclose their own breach figures.” Data compromised in this attack
included Americans’ names and social security numbers (SSNs), according
to Comparitech.
While this ransomware attack did not directly target an
energy sector firm, the breach highlights the leading role of supply-chain and
third-party risks to energy sector firms, a pervasive theme that Resecurity
will expound upon throughout this report.
There were several independent ransomware operators
identified, such as the "spin-off" of Babuk Ransomware,
which is now under the management of new owners. The group has targeted
Nuclebrás Equipamentos Pesados S.A., commonly shortened to NUCLEP, a Brazilian
state-owned nuclear company specialized in nuclear engineering. In fact,
the stolen data for sale, presumably exfiltrated from this victim organization,
was offered for sale almost eight months ago by another ransomware group known
as 'Meow' or 'Meow Leaks'. Notably, the new spin-off of the
prominent ransomware group has leaked several exclusive files that were not
previously available at 'Meow Leaks,' which may add to their
credibility. At the same time, there is a significant difference in the
volume of data offered for sale. The original 'Meow Leaks' included only 250 GB
of data, while the actors calling themselves 'Babuk' are offering 1.7 TB, which
could be misleading. Likely, these actors were familiar with the root cause of
the original leak and could interact with the access broker responsible for
unauthorized access. Considering the specifics of work surrounding such
enterprises, cybercriminals aim to profit from sensitive R&D; that's why
they set an extremely high price amplified by speculative narratives.
The actors had an ambitious plan to extort the victim
organization and demanded over $500,000 as ransom payment. They also offered an
option for exclusive acquisition for $1.5 million. It is not clear if they were
successful in receiving any payment, but the data had been removed along with
their DLS for some time before later emerging again under the new brand of
Babuk. In fact, Resecurity does not connect this reincarnation with the
original Babuk Ransomware, but the actors are capitalizing on their brand in
the underground world.
Notably, the same group attempted to extort the Malaysian
Nuclear Energy Agency in the past. Samples of stolen data, including employee
records, have been published on a Telegram channel and Pastebin. In
fact, the initial access to this victim was offered for sale earlier on the
Dark Web just for $5,000 (described in the next sections of this report).
But in terms of ransomware-related energy data leak
activity, the most prolific threat actor groups observed by HUNTER over the
last six months are Cl0P and HellCat. While Cl0P is
believed to be a Russia-nexus ransomware collective, HellCat appears
to be comprised of multiple native English-speaking members, the most prominent
being ‘Pryx’ and ‘Rey.’
Over the last five months, an access broker many researchers
presumed to be associated with Cl0P, and who goes by the aliases ‘AntiBrok3rs’
and ‘Nam3L3ss,’ has leaked data from at least 15 energy sector victims
that were initially compromised by the ransomware gang’s 2023 MOVEit supply-chain
attack. The threat actor posted these data leaks on Breach Forums.
However, AntiBrok3rs publicly denied any
affiliation with Cl0P in a December 2024 Breach Forums post
titled “Putting cl0p ties to bed for good.”
In the post, AntiBrok3rs writes “I have no
ties to any ransom group, I have never even spoken with anyone from any ransom
group, at least to me knowledge.” Nevertheless, since November 2024, this
threat actor has been publicizing leak data from dozens of MOVEit victims,
including numerous American energy utilities and service providers.
In the screenshots below, the reader can see various of
leaks of personally identifying information (PII) that are linked to either
energy utility customers or employees or both. Some of these victims include
Texas-based utilities CenterPoint Energy and Entergy, along with Nevada Energy,
and Appalachian Power.
Notably, data from these utilities was compromised from a
single MOVEit victim, CLEAResult. CLEAResult is the “largest energy efficiency,
energy transition and energy sustainability program consultant in North
America,” according to their website. Utility victims shamed by AntiBrok3rs appear
to have partnered with CLEAResult to “design and implement their programs,” as
indicated by the consultant’s website.
The compromise of these utility companies, which are
fourth-party victims to the primary MOVEit managed file transfer breach,
highlight the magnitude of cyber supply-chain risk that energy operators must
manage today. By breaching MOVEit, Cl0P was not only able to
compromise the MFT platforms’ customers, but third parties of those customers
as well (fourth parties), exposing a downstream cascade of impacted vendors and
clients.
Highlighting the pronounced cyber supply-chain risks facing
the energy industry, a joint study published by
SecurityScorecard and KPMG in October 2024 found that third-party breaches
drive almost half (45%) of malicious intrusions in this sector. According to
SecurityScorecard, this figure is “significantly higher than the global rate of
29%. Additionally, 90% of companies that suffered multiple breaches were hit
via third-party vendors.”
SecurityScorecard also found that “software and IT vendors
outside the energy sector are the main source of third-party breaches.” Of the
incidents they reviewed, SecurityScorecard attributed 67% of third-party
breaches to software and IT vendors, “with only four involving other energy
companies.”
Beyond Cl0P-nexus activity, threat actors
connected to the HellCat ransomware group have also been
prolific leakers of energy company data. Notably, HellCat claimed
responsibility for the November 2024 intrusion of ransomware attack against
Schneider Electric, a French multinational energy management firm. Notably,
the HellCat ransomware attack marked the third time Schneider
Electric had been breached over the preceding 18 months.
HellCat claimed they gained access to the firm
via the company Altassian Jira systems. Jira is a project management and
issue/bug-tracking tool that is often used by software development teams.
According to BleepingComputer, the platform “often contains sensitive
data, such as source code, authentication keys, IT plans, customer information,
and internal discussions related” to these software development projects.
Notably, HellCat frequently breaches
victims by compromising Jira servers. Additionally, a cyber-threat intelligence
expert interviewed by BleepingComputer said that HellCat’s
signature tactic involves “exploiting Jira credentials harvested from
compromised employees that were infected by infostealers.”
In fact, this was the precise staging vector that
enabled HellCat to compromise Schneider’s Jira server, according to Hudson Rock
research. Specifically, HellCat infected a Schneider Electric employee with
Lumma infostealer malware, one of the most prominent infostealer families in
the cybercrime ecosystem.
In a ransom announcement that has since been removed
from HellCat’s data leak site (DLS), the threat group claimed the
“breach has compromised critical data, including projects, issues, and plugins,
along with over 400,000 rows of user data, totaling more than 40GB Compressed
Data.” In an attempt to be funny, HellCat demanded a “payment
of $125,000 USD in Baguettes” to “secure the deletion of this data and prevent
its public release.”
It’s not clear if Schneider Electric complied with this
specific request, but their ransom announcement is no longer listed on HellCat’s
victim-shaming blog. Notably, the nature of this ransom request is distinctly
uncharacteristic of those associated with Russia-nexus threat groups, which
always demand payment in crypto. This atypically juvenile publicity stunt
further guides Resecurity’s medium-confidence assessment that the group’s
leadership is unaffiliated with more traditional Russia and CIS-nexus
ransomware ecosystems.
Regardless, HellCat-affiliated threat actors
like ‘miya’ have listed access to numerous energy sector victims
spanning the globe. Over the last six months miya has
published the following access listings on Breach Forums:
- VPN
credentials for a “Spanish coal trade and energy solutions” firm - Root
server access for a Japanese renewable energy company - Root
server access for a $9 billion revenue French energy distribution firm - Root
access to an asset management server for a UK nuclear and defense
contractor Listings for these access offerings range from $300 to $800.
While the nuclear defense contractor listing is obviously the most alarming,
the targeting of renewable energy firms is also noteworthy. Additionally,
Resecurity assesses that the nuclear defense contractor access posting is more
bluster than an actionable intrusion vector.
Regarding the growing threat to renewable energy, the
Federal Bureau of Investigation warned private
industry in July 2024 that threat actors are increasingly seeking to “disrupt
power generating operations, steal intellectual property, or ransom information
critical for normal functionality to advance geopolitical motives or financial
gain within the US renewable energy industry.”
The FBI also noted that “structural shifts in the reduced
cost of implementation of renewable energy and incentives for development of
clean energy have created new targets and opportunities for cyber threat actors
to disrupt and exploit for their own gain.” However, the risks highlighted by
the FBI are largely applicable to any rapidly growing industry that relies
heavily on IIoT-connected devices, according to a UtilityDive report.
Critical infrastructure security experts interviewed
by UtilityDive also noted how many renewable energy firms
“rely heavily on vendors and third-party organizations for operation and
installation.” These enhanced supply-chain dependencies have significantly
increased renewable firms’ attack surfaces, making them much easier to breach.
Access & Data Brokers
Other notable energy sector data leaks and access listings
observed by Resecurity, and which are at heightened risk of being weaponized by
ransomware actors and other threat actors, include:
- 30 GB
of confidential data from Qatar Gas, ADNOC Offshore, and Bell Energy - Office
365 Exchange Access for a U.S. energy firm that generates $6 billion in
annual revenue - Network
remote code execution access to “the largest energy company in North
Africa”
The Emirates-focused data leaks were published on the XSS
cybercrime forum on December 28, 2024. QatarGas has recently rebranded as
QatarEnergy LNG. The firm is the largest liquefied natural gas company in the
world. In the context of the Gaza conflict, the listing of sensitive data
connected to this firm is notable and may suggest possible geopolitical
motivations.
QatarEnergy is also in the process of developing a
$5 billion offshore “megaproject” in a large oil field located in the Persian
Gulf, that the Qatari nation jointly owns and shares with Iran.Meanwhile, ANODC
Offshore is the largest offshore oil producer in Abu Dhabi. Bell Energy (The
Bell Group) is also headquartered in Abu Dhabi. The threat actor who leaked
this confidential, Emirates-focused energy data goes by the handle ‘cyberdluffy’
on the XSS forum.
Another noteworthy posting is the Office 365 Exchange access
listing for a U.S. energy firm that generates $6 billion in annual revenue.
This access listing was posted on the XSS forum on October 16, 2024 by a threat
actor who goes by the handle ‘johnsherlock.’ The threat actor listed
this access offering for $15,000 USD.
Notably, Microsoft Office 365 has been aggressively targeted
by nation-state actors like Midnight Blizzard, AKA NOBELIUM.
According to Microsoft threat intelligence analysts,
“Midnight Blizzard is a Russia-based threat actor attributed by the
US and UK governments as the Foreign Intelligence Service of the Russian
Federation, also known as the SVR.” Microsoft also said this “threat actor is
known to primarily target governments, diplomatic entities, non-governmental
organizations (NGOs) and IT service providers, primarily in the US and Europe.”
Analyzing a malicious campaign that targeted Exchange web
services in January 2024, Microsoft noted that threat actors like Midnight
Blizzard “compromise user accounts to create, modify, and grant high
permissions to OAuth applications that they can misuse to hide malicious
activity.” In this campaign, Midnight Blizzard compromised a
legacy test 0Auth application to “grant them the Office 365 Exchange Online
full_access as_app role, which allows access to mailboxes.”
While there is no substantive link between the johnsherlock access
broker persona and Midnight Blizzard, the critical nature of this
type of access listing, combined with the geoeconomically sensitive nature of
the victim’s industry category (energy), and the relatively high price of the
listing, merit closer investigation. If anything, access postings like this
illustrate how the line between financially motivated and nation-state
cyber-threat activity can often be blurry.
The final noteworthy energy-sector access listing observed
by Resecurity is the Breach Forum post that promoted network remote code
execution (RCE) access to the “largest energy company in North Africa.” The
threat actor who posted this listing is Belsen Group, a nascent,
illicit access broker group that gained notoriety in
January 2025 for their leak of “configurations from over 15,000 compromised
FortiGate firewalls.” Belsen Group has been classified by
the cyber threat intelligence (CTI) community as an illicit data broker.
Belsen Group posted their North African energy
sector access listing on February 10, 2025, and priced the offering at $20,000
USD.
Based on the annual revenue information provided by the
threat actor, the alleged victim listed does not appear to be the largest
energy company in North Africa. That distinction belongs to Sonatrach, the
national state-owned oil company of Algeria, which generates over $77 billion
in annual revenue. However, it’s possible Belsen Group misstated
the annual revenue for the victim they were claiming.
Hacktivism
Hacktivism is another leading threat targeting the energy
sector. Hacktivism is the act of staging cyberattacks in the furtherance of
social, political, or ideological change. Most of the geopolitically inspired
hacktivist activity documented since the start of the 2022 Ukraine war has
manifested as low-level DDoS attacks or web defacements.
But over the last year, HUNTER analysts have observed
numerous hacktivist groups claiming successful attacks on energy sector targets
in the furtherance of causes aligned with the Russo-Ukraine war and the Gaza
conflict. Two prominent pro-Russia hacktivist groups that have generated
publicity for their energy-sector targeting, despite general skepticism
regarding their claims, are ‘Z-Pentest’ and its partner
organization, ‘Sector 16’ (S16).
A December 2024 Cyble report noted
that Z-Pentest has “posted videos to their Telegram channels
allegedly showing members tampering with operational technology controls (OT),
most notably in the oil and gas and water system sectors.”
Cyble noted that those claims “may largely be intended to
establish credibility rather than inflict damage on targets.” However, Cyble
expressed alarm that, in December, Z-Pentest’s claims “escalated to
include disrupting one U.S. oil well system.” Notably, Z-Pentest claims
to be based out of Serbia. The group is also aligned with various anti-NATO and
pro-Palestine hacktivist groups.
According to the December Cyble report, Z-Pentest claimed
to have disrupted “critical systems at an oil well site, including systems
responsible for water pumping, petroleum gas flaring, and oil collection.” A
6-minute screen recording posted by the threat actor showed “detailed
screenshots of the facility’s control systems, showing tank setpoints, vapor
recovery metrics, and operational dashboards allegedly accessed and changed
during the breach,” according to Cyble.
In a March 2025 interview with
Spanish cybersecurity firm Miólnir, a spokesperson for Z-Pentest pontificated
on their hacktivist motivations. This interview was facilitated by another
pro-Russia hacktivist group called ‘Noname057(16)’ that we will
elaborate on in the following section.
In the Miólnir interview, the Z-Pentest spokesperson
referenced the disastrous White House meeting between the Ukrainian and
American heads of state, as the commented on the current geopolitical
situation:
“We're always on Russia's side, no need to guess. As for
Zelensky's circus show in the Oval Office, well, he's better at comedy than
military strategy. By the way, we like how Trump mocks the fictional state; at
least he has a sense of humor.
As for Europe's leaders… Well, they're a bunch of lost
people who don't understand who or what they're dealing with. If they think
they're safe, we have to disappoint them: no, they're not. We're everywhere.
Anyone who opposes the Russians is signing a one-way
ticket with no return. We don't care who decided to play with fire; we will
always defend our own and destroy everything that stands in our way. Want to
try your luck? Well, good luck. You'll need it.”
Z-Pentest also denied receiving financial
support from state-sponsored actors, telling Miólnir:
“Every time we hear about being sponsored by a
government, we laugh so hard we snort coffee. We're not dependent on any
country's budget! We have an international crew, and if they made a movie about
us, it would be a real box office hit. We're like a big family, where everyone
truly lives in harmony (well, except for those who always eat the last slice of
pizza).
But if someone decides to support us, say, with a cup of
coffee or something stronger—we won't say no!”
However, since the start of 2025, S16 has been
the most prolific Russia-nexus hacktivist group targeting the energy sector.
Like Z-Pentest, S16 also claims to be based out of
Serbia. Including a joint S16-Z-Pentest attack on the
Supervisory Control and Data Acquisition (SCADA) system managing oil pumps and
storage tanks in Texas, announced in January, S16 has claimed
responsibility for five energy-sector attacks around the world.
In the Texas SCADA attack, S16 claimed the
“system was hacked and completely broken, oil production was stopped, the
system was completely destroyed.” However, these claims remain unverified and
should be treated with skepticism. Hacktivist groups frequently exaggerate the
impact of their breaches to generate hype and spread disinformation. The
now-defunct, Russia-nexus DDoS group KillNet is a prime
example of this modus operandi.
Beyond the U.S., the group has targeted energy firms in
France and Germany. The group’s most recent energy-sector attack claims
centered on German “process cooling and refrigeration” firm GEA. The company’s
website notes that “GEA’s process refrigeration and gas compression
technologies have demonstrated reliable performance in oil & gas, chemical,
petrochemical,” and other applications.
On February 9, S16 announced on their
official Telegram channel that they had “attacked the automated control system
of the equipment for the natural gas cooling system of the company GEA
." S16 also claimed the attack was enabled by human
error, as “access was obtained by easy brute force of the server,” which
allowed the hacktivists gain “full access to the system and its control.”
S16 has also been observed partnering with
Russia-based hacktivist group OverFlame to target energy
facilities. In January, S16 announced they collaborated with OverFlame to
attack the “hydroelectric power plants of France, the company
"DYNELEC" in the city of Maser-sur-Salat!”
(PICTURE WOULDN'T LOAD TO THIS, SOMETHING IN THE PICTURE THE CASES SYSTEM DOESN'T LIKE)
The threat actors claimed the attack inflicted the following
cyber-physical damage: “The valves were broken, the seals were damaged by
increasing the pressure, the server failed, the flow power in the group
settings was increased, which will inevitably lead to wear of the equipment and
strategically important parts for work.” Again, these claims remain unverified.
On the Gaza front, leading anti-Israel hacktivist groups
engaged in this conflict include ‘CyberAv3ngers’ and ‘Handala.’
Both threat actor groups have been observed targeting the energy sector. A
Cybersecurity & Infrastructure Security Agency announcement that was last
revised in December 2014 advisory described CyberAv3ngers as
a persona used by threat actors affiliated with the Iranian Government’s
Islamic Revolutionary Guard Corps (IRGC).
The CISA advisory noted how CyberAv3ngers’ malicious
campaigns began in November 2023, just one month after the October 7 massacre.
Around this time, these IRGC-affiliated threat actors “began actively targeting
and compromising Israeli-made Unitronics Vision Series programmable logic
controllers (PLCs) and human machine interfaces (HMIs),” according to CISA.
CISA also noted that CyberAv3ngers left
defacement images on victim websites stating, “You have been hacked, down with
Israel. Every equipment ‘made in Israel’ is CyberAv3ngers legal target.” PLCs
targeted in this attack campaign are “commonly used in the Water and Wastewater
Systems (WWS) Sector and used in other industries including, but not limited
to, energy, food and beverage manufacturing, transportation systems, and
healthcare,” according to CISA.
Again, CyberAv3ngers’ targeting activities
highlight the unique supply-chain threat that energy sector firms face,
particularly in the context of external geopolitical conflicts. In this
IRGC-nexus campaign, for example, all critical digital assets (CDAs)
manufactured by Israel have been deemed legitimate military targets, thus
threatening enterprise customers of these products with potentially
catastrophic collateral damage.
Handala is another prolific Gaza-nexus threat
actor that has attracted the attention of the CTI community for their bold
claims of energy sector hack-and-leak operations and similar campaigns in other
sectors. Regionally, Handala’s targeting has been focused on
Israeli entities.
In a July 2024 CTI report documenting a Handala wiper
malware campaign that opportunistically exploited the widespread CrowdStrike
Falcon outage,
Trellix said the group “at least pretends to act based on pro-Palestinian
motives,” but cautioned this posturing could be a “façade for an ulterior
motive.” This assessment is common for most high-level hacktivist activity,
which can easily serve as cover for nation-state espionage or disinformation
operations.
Energy sector victims allegedly compromised by Handala include:
- BLEnergy
– a leading battery energy storage systems (BESS) integrator and provider
in Israel - ELitech
- a company providing engineering and project management services to
renewable energy, private power plants, gas insulated substations (GIS),
defense and military projects, and projects requiring a high degree of
technological expertise
In July 2024, Handala published a post on
the RAMP cybercrime forum announcing that the hack and leak of 145 GB of data
belonging to BLenergy. This attack again highlights the growing threat to
companies that operate in the renewable energy space.
Highlighting related supply-chain risks and targeting, Handala’s
post noted that exactly one month prior to their claimed attack, “CATL signed a
billion dollar contract with BLEnergy.” “CATL is the leading battery
manufacturer in the world in the fields of electric vehicles and energy
storage,” according to Handala’s post.
Handala also warned the victim to “think about
the consequences of cooperation in our occupied lands and do not try our
patience more than that! We will leak all the data! Our backdoor is still
active in hundreds of Zionist companies, so we are looking for the right
opportunity to attack!”
In April 2024, the threat actor also announced on the RAMP
forum that they had hacked and leaked 4.9 terabytes of data belonging to
Elitech. Notably, this attack included the hashtags #OpIsrael and #OpJerusalem.
Resecurity has previously chronicled #OpIsrael-related hacktivist campaigns that
ensued in the wake of the October 7 massacre.
Nuclear Access and Data Leaks
Alarmingly, threat actors have also escalated their
targeting of the nuclear sector. These attacks have ranged from intricate job
recruitment and phishing schemes targeting nuclear sector personnel to
allegations of stolen data, access listings, and claims of successful DDoS
attacks.
Over the last year, the most notorious adversary confirmed to
have attacked nuclear sector targets is Lazarus Group, a North
Korean state-backed advanced persistent threat (APT) group that has gained
infamy for its high-ticket crypto hacks. In December 2024, Kaspersky documented
their findings from a Lazarus campaign they dubbed “Operation
DreamJob.”
An investigation conducted by Kaspersky revealed that
several employees from a nuclear-related organization were “infected via three
compromised archive files appearing to be skill assessment tests for IT
professionals.” This ongoing campaign “leverages a range of advanced malware,
including a newly discovered modular backdoor, CookiePlus, that was disguised
as open-source plugin,” according to Kaspersky.
(PICTURE WILL NOT LOAD)
Framatome “designs, manufactures, and installs components,
fuel and instrumentation and control systems for nuclear power plants and
offers a full range of reactor services,” according to the company’s Wikipedia
page.
Noname057(16) claimed to have conducted two more
nuclear sector DDoS attacks on April 1, 2025. These attacks allegedly impacted
the public-facing websites targets in Belgium: Doel and Tihange. The facilities
represent half of
Belgium’s four nuclear reactors, according to the World Nuclear Association.
(PICTURE WILL NOT LOAD)
It is unclear how effective or impactful Noname057(16)’s
DDoS attacks on these three nuclear targets were. However, it should be noted
that there was no risk to the proper functioning of OT and related critical
digital assets (CDAs) in the nuclear facilities publicly shamed by the threat
actor.
The primary reason it is extremely difficult to compromise
or otherwise disrupt nuclear power operations through cyber-enabled means is
that these energy facilities mandate the implementation of air-gapped networks
by default. This means that industrial control systems (ICS), SCADA
infrastructure, and other CDAs are physically isolated from the external
networks, including the public Internet.
Additionally, these facilities enforce extremely strict
network segmentation between business IT and physical OT networks. In theory,
this framework makes lateral movement from a compromised IT system into an OT
environment impossible. Furthermore, the data flow in nuclear energy facilities
is designed to be unidirectional by default. This mean that data can only flow
out of the plant environment, while no data is allowed to enter the facility’s
network.
According to Mark Rorabaugh, the President of InfraShield, a
critical infrastructure security firm with unique expertise in protecting
nuclear power facilities, the primary risk to these entities emerges from
physical sabotage conducted by malicious insiders. “The specific attack vector
that nuclear energy operators must be on high alert for is malicious portable
media introduced into the plant environment by a rogue employee or contractor,”
according to Rorabaugh.
Nevertheless, while Noname057(16)’s attacks are
relatively unsophisticated, HackManac highlighted them
as the most active threat group for the week dated March 19-25 2025. The threat
group accounted for 135 of 574 confirmed cyberattacks that week, illustrating
their significant level of threat activity. The group’s second-degree (and
perhaps more expansive links) to S16 is also a nexus
nuclear-sector defenders should monitor closely, given the latter’s alarming
and increasing claims of successfully compromising OT and SCADA systems.
Significance
Resecurity’s second energy-sector CTI report documents the
HUNTER unit’s latest findings of malicious activity targeting these critical
infrastructure organizations. In a geopolitical backdrop fractured by ongoing
conflicts in Ukraine and Gaza, HUNTER’s findings largely demonstrate how
military hostility is projected into cyberspace and how ancillary cybercriminal
ecosystems support the malicious targeting of energy firms.
For energy-sector defenders, the findings of this report
should serve as a warning that threat actors are escalating their attacks on
these critical infrastructure organizations and growing increasingly bolder
when it comes to targeting their OT networks. In this threat landscape, the
potential for a catastrophic cyber-physical attack that causes environmental or
human harm is rapidly increasing.
The most prominent threat actors recently identified by
HUNTER as actively targeting the energy sector include the following:
- RansomHub/DragonForce [Ransomware]
- HellCat [Ransomware]
- Lazarus
Group [Nation-State] - Cyb3rAv3ngers [Nation-State]
- S16 [Hacktivist]
- Noname057(16) [Hacktivist]
Based on this compilation of leading threat actors,
defenders should be especially aware of HellCat’s tactics,
techniques, and procedures (TTPs), specifically their reliance on infostealer
attack chains, with an emphasis on Lumma malware. Given this targeting
activity, defenders should regularly conduct comprehensive dark web monitoring
to audit their personnels’ and IT/software supply-chain partners’ exposure to
credential compromise. The latter is particularly vital as SecurityScorecard
and KMPG research revealed that the IT and software supply chain is the energy
sector’s weakest link.
Conclusion
In response to these growing threats, the U.S. Department of
Energy (DOE) issued new cybersecurity guidelines for electric
distribution systems and distributed energy resources (DER) in 2024. These
guidelines, developed in collaboration with the National Association of
Regulatory Utility Commissioners (NARUC), aim to provide a common framework for
reducing risk and improving the cyber resilience of critical infrastructure.
Resecurity warns about the increase in targeted cyberattacks
against enterprises in the energy sector worldwide. Some of these attacks
represent much larger campaigns designed to target country-level
infrastructure, acting as tools for geopolitical influence. It is expected that
nation-state actors and foreign intelligence will leverage this approach as a
new generation of warfare in the future, where the role of cybercriminal actors
may be significant, enabling further cyberattacks and providing infrastructure
and resources to conduct offensive cyber operations.
