In recent months, the cybersecurity landscape has been significantly impacted by the activities of Iranian state-sponsored cyber actors. The scope and sophistication of these attacks have reached alarming levels, targeting critical infrastructure in collaboration with major non-state ransomware groups. The latest advisories from U.S. cybersecurity agencies highlight the growing threat posed by Iranian-linked groups, emphasizing the urgent need for enhanced protective measures.
Cybersecurity Advisory Report
On August 28, The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Defense Cyber Crime Center (DC3) issued a comprehensive Cybersecurity Advisory detailing the intensified activities of Iranian-linked cyber actors. The advisory revealed that the Iranian government is leveraging ransomware gangs to target organizations in the U.S., Israel, Azerbaijan, and the UAE. Iranian threat actors, identified by names such as Pioneer Kitten, Lemon Sandstorm, Rubidium, and others, have been active since 2017 and are known for targeting critical sectors, including education, finance, healthcare, and defense. These actors deploy ransomware and use broader cyber espionage campaigns to steal sensitive data.
A significant aspect of these operations involves using a cover company named Danesh Novin Sahand (ID:14007585836), which helps mask the true origin of the cyberattacks. By using this company as a front, Iranian hackers can obscure their governmental ties and operate under the guise of a legitimate IT firm. This strategy aids in both evading detection and providing a layer of plausible deniability. The hackers exploit vulnerabilities in widely used products, including those from Check Point, Palo Alto Networks, and Ivanti, to infiltrate networks. As reported, they create fake accounts, disable security systems, and use cloud resources to facilitate further attacks. According to the FBI, the group was notably behind the Pay2Key ransomware operation in 2020, which aimed to embarrass Israeli organizations rather than seeking ransom publicly. Iranian-backed hackers, specifically the Fox Kitten group, have utilized the Pay2Key ransomware to target Israeli companies as part of a broader cyber confrontation with Israel. This operation appears to be aimed at creating panic and fear, possibly as a form of information warfare and retaliation following recent tensions, such as the assassination of an Iranian nuclear scientist. The advisory stresses the need for organizations to address specific vulnerabilities and report cyber incidents to bolster defense activities, facilitating their operations and providing a facade for their malicious actions.
The advisory also notes similarities with a previous alert from September 2020 concerning Iran-based threat actors exploiting VPN vulnerabilities. The recent advisory provides updated indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) derived from ongoing investigations and technical analyses. These insights reveal a consistent pattern of cyber activity aimed at maintaining and exploiting access to victim networks to enable future ransomware attacks. Using compromised credentials and exploiting vulnerabilities in internet-facing assets are reportedly common tactics among these cyber actors. Specific vulnerabilities identified include CVE-2024-24919 and CVE-2024-3400, affecting the products of cybersecurity companies Check Point Software Technologies, Ltd and Palo Alto Networks, Inc. More specifically, CVE-2024-24919 is a security issue in Check Point systems that allows hackers to break into devices by exploiting weak password protections, especially in remote access setups. This can give them control over important parts of the system. At the same time, CVE-2024-3400 affects Palo Alto Networks’ firewall software, where hackers can take advantage of a weakness to run harmful commands on a device, potentially gaining full control over it if the system is not patched. These vulnerabilities allow Iranian actors to gain unauthorized access to networks, facilitating ransomware deployment and other malicious activities.
Allied Ransomware Groups
A significant concern is the direct collaboration between Iranian cyber actors and prominent ransomware groups such as NoEscape, Ransomhouse, and ALPHV (BlackCat). These ransomware groups are notorious for their sophisticated encryption methods and extortion strategies. Recent findings indicate that Iranian actors are not merely facilitating these attacks but are actively involved in the operations, including strategizing ransomware deployment and sharing access with affiliates.
NoEscape emerged as a key player in the ransomware domain in 2020, and it is known for its aggressive tactics involving data encryption and theft. The group employs advanced encryption techniques and demands substantial ransoms, making it a formidable threat in the ransomware landscape. Their collaboration with Iranian actors highlights the evolving nature of ransomware operations, where state-sponsored actors provide initial access and support to enhance the impact of ransomware attacks.
Ransomhouse is another significant ransomware group that combines data encryption with the theft of sensitive information. This dual approach increases pressure on victims, as they face both operational disruptions and the risk of having their stolen data exposed. Ransomhouse’s methodical and high-value targeting aligns with the broader strategy of Iranian-linked cyber actors to leverage ransomware for geopolitical objectives.
ALPHV (BlackCat), known for its ransomware-as-a-service model, represents an advanced and scalable approach to ransomware. The group’s model allows affiliates to use its infrastructure for attacks in exchange for a share of the ransom payments. The sophistication of ALPHV’s operations, combined with Iranian actors’ involvement, underscores the increasing complexity of ransomware threats and the need for robust defense strategies.
Iranian threat actors, identified by names such as Pioneer Kitten, Lemon Sandstorm, Rubidium, and others, have been active since 2017 and are known for targeting critical sectors, including education, finance, healthcare, and defense.
Threats to Critical Infrastructure
One of the most alarming developments is targeting critical infrastructure, particularly water systems. This has been an ongoing threat since November 2023, when an incident in Pennsylvania in which the water facility controller was hacked and replaced with a message stating, “YOU HAVE BEEN HACKED.” A few months later, a letter from National Security Advisor Jake Sullivan and Environmental Protection Agency Administrator Michael Regan, released on 20 March 2024, also warned of disruptive cyberattacks on water and wastewater systems across the U.S. The letter highlights that both Iranian and Chinese hackers are involved in these attacks, with Iranian cyber actors allegedly linked to the Iranian Islamic Revolutionary Guard Corps (IRGC).
Although no immediate damage to the water system was reported, the incident reveals the critical vulnerability of water and sewage plants, which are essential for public health and safety. The U.S. government’s warning emphasizes the need for state governors to ensure that water systems comprehensively assess their cybersecurity practices and prepare for potential cyber incidents. The focus on water systems reflects a broader strategic objective, where disrupting essential services can have significant operational and societal impacts.
In response, recent reports from Google’s Mandiant unit and Microsoft have exposed sophisticated Iranian cyber operations aimed at intelligence gathering and targeting local individuals suspected of collaborating with Iran’s adversaries. Namely, more than 40 fake recruiting websites written in Farsi and Arabic were discovered, most of them offering jobs in Israel. These websites lured visitors by asking them to submit personal information and other sensitive data under the pretense of job opportunities. The campaign, which ran from as early as 2017 until March 2024, appeared to target individuals in the IT, cybersecurity, and human resources fields. Mandiant also uncovered several fake social media accounts across platforms like Twitter, Telegram, YouTube, and Iran’s Virasty, which were used to promote these phony recruiting firms. The websites were designed to look like Israeli companies operated them, but the intent was to gather intelligence. Several of these fake sites are specifically aimed at recruiting military personnel, particularly those in the army, security services, and intelligence from Syria and Hezbollah in Lebanon. This effort mirrors similar campaigns allegedly run by proxy groups in Syria and Lebanon, further raising concerns about its role in espionage and data theft.
Meanwhile, Microsoft’s study highlights the use of custom malware named Tickler by the Iranian Islamic Revolutionary Guard Corps (IRGC) to infiltrate critical sectors in the U.S. and UAE for intelligence purposes. As reported, between April and July, Microsoft observed the group deploying Tickler in cyberattacks targeting industries such as satellite communications, oil and gas, and federal and state government sectors in the U.S. and the United Arab Emirates. The campaign is part of broader, long-standing cyber operations aimed at supporting Iran’s intelligence objectives. Microsoft tracks the group behind the campaign as Peach Sandstorm, which has used techniques like fake LinkedIn profiles to conduct social engineering and intelligence collection since 2021. These activities reflect Iran’s increasingly sophisticated cyberespionage capabilities, bolstered by tech transfers from Russia.
