The cybercrime group called GhostSec has been linked to a Golang variant of a ransomware family called GhostLocker.

“TheGhostSec and Stormous ransomware groups are jointly conducting double extortion ransomware attacks on various business verticals in multiple countries,” Cisco Talos researcher Chetan Raghuprasad said in a report shared with The Hacker News.

“GhostLocker and Stormous ransomware have started a new ransomware-as-a-service (RaaS) program STMX_GhostLocker, providing various options for their affiliates.”

Attacks mounted by the group have targeted victims in Cuba, Argentina, Poland, China, Lebanon, Israel, Uzbekistan, India, South Africa, Brazil, Morocco, Qatar, Turkiye, Egypt, Vietnam, Thailand, and Indonesia.

Some of the most impacted business verticals include technology, education, manufacturing, government, transportation, energy, medicolegal, real estate, and telecom.

GhostSec – not to be confused with Ghost Security Group (which is also called GhostSec) – is part of a coalition called The Five Families, which also includes ThreatSec, Stormous, Blackforums, and SiegedSec.

It was formed in August 2023 to “establish better unity and connections for everyone in the underground world of the internet, to expand and grow our work and operations.”

Late last year, the cybercrime group ventured into ransomware-as-a-service (RaaS) with GhostLocker, offering it to other actors for $269.99 per month. Soon after, the Stormous ransomware group announced that it will use Python-based ransomware in its attacks.

The latest findings from Talos show that the two groups have banded together to not only strike a wide range of sectors, but also unleash an updated version of GhostLocker in November 2023 as well as start a new RaaS program in 2024 called STMX_GhostLocker.

“The new program is made up of three categories of services for the affiliates: paid, free, and another for the individuals without a program who only want to sell or publish data on their blog (PYV service),” Raghuprasad explained.

STMX_GhostLocker, which comes with its own leak site on the dark web, lists no less than six victims from India, Uzbekistan, Indonesia, Poland, Thailand, and Argentina.

GhostLocker 2.0 (aka GhostLocker V2) is written in Go and has been advertised as fully effective and offering speedy encryption/decryption capabilities. It also comes with a revamped ransom note that urges victims to get in touch with them within seven days or risk getting their stolen data leaked.

The RaaS scheme also allows affiliates to track their operations, monitor encryption status, and payments through a web panel. They are also provided with a builder that makes it possible to configure the locker payload according to their preferences, including the directories to encrypt and the processes and services to be terminated before commencing the encryption process.

Once deployed, the ransomware establishes connection with a command-and-control (C2) panel and proceeds with encryption routine, but not before killing the defined processes or services and exfiltrating files matching a specific list of extensions.

Talos said it discovered two new tools likely used by GhostSec to compromise legitimate sites. “One of them is the ‘GhostSec Deep Scan toolset’ to scan legitimate websites recursively, and another is a hack tool to perform cross-site scripting (XSS) attacks called “GhostPresser,'” Raghuprasad said.

GhostPresser is mainly designed to break into WordPress sites, allowing the threat actors to alter site settings, add new plugins and users, and even install new themes, demonstrating GhostSec’s commitment to evolving its arsenal.

“The group themselves has claimed they’ve used it in attacks on victims, but we don’t have any way to validate any of those claims. This tooling would likely be used by the ransomware operators for a variety of reasons,” Talos told The Hacker News.

“The deep scan tool could be leveraged to look for ways into victim networks and the GhostPresser tool, in addition to compromising victim websites, could be used to stage payloads for distribution, if they didn’t want to use actor infrastructure.”

Hackers backed by Iran and Hezbollah staged cyber attacks designed to undercut public support for the Israel-Hamas war after October 2023.

This includes destructive attacks against key Israeli organizations, hack-and-leak operations targeting entities in Israel and the U.S., phishing campaigns designed to steal intelligence, and information operations to turn public opinion against Israel.

Iran accounted for nearly 80% of all government-backed phishing activity targeting Israel in the six months leading up to the October 7 attacks, Google said in a new report.

“Hack-and-leak and information operations remain a key component in these and related threat actors’ efforts to telegraph intent and capability throughout the war, both to their adversaries and to other audiences that they seek to influence,” the tech giant said.

But what’s also notable about the Israel-Hamas conflict is that the cyber operations appear to be executed independently of the kinetic and battlefield actions, unlike observed in the case of the Russo-Ukrainian war.

Such cyber capabilities can be quickly deployed at a lower cost to engage with regional rivals without direct military confrontation, the company added.

One of the Iran-affiliated groups, dubbed GREATRIFT (aka UNC4453 or Plaid Rain), is said to have propagated malware via fake “missing persons” site targeting visitors seeking updates on abducted Israelis. The threat actor also utilized blood donation-themed lure documents as a distribution vector.

At least two hacktivist personas named Karma and Handala Hack, have leveraged wiper malware strains such as BiBi-Windows Wiper, BiBi-Linux Wiper, ChiLLWIPE, and COOLWIPE to stage destructive attacks against Israel and delete files from Windows and Linux systems, respectively.

Another Iranian nation-state hacking group called Charming Kitten (aka APT42 or CALANQUE) targeted media and non-governmental organizations (NGOs) with a PowerShell backdoor known as POWERPUG as part of a phishing campaign observed in late October and November 2023.

POWERPUG is also the latest addition to the adversary’s long list of backdoors, which comprises PowerLess, BellaCiao, POWERSTAR (aka GorjolEcho), NokNok, and BASICSTAR.

Hamas-linked groups, on the other hand, targeted Israeli software engineers with coding assignment decoys in an attempt to dupe them into downloading SysJoker malware weeks before the October 7 attacks. The campaign has been attributed to a threat actor referred to as BLACKATOM.

“The attackers […] posed as employees of legitimate companies and reached out via LinkedIn to invite targets to apply for software development freelance opportunities,” Google said. “Targets included software engineers in the Israeli military, as well as Israel’s aerospace and defense industry.”

The tech giant described the tactics adopted by Hamas cyber actors as simple but effective, noting their use of social engineering to deliver remote access trojans and backdoors like MAGNIFI to target users in both Palestine and Israel, which has been linked to BLACKSTEM (aka Molerats).

Adding another dimension to these campaigns is the use of spyware targeting Android phones that are capable of harvesting sensitive information and exfiltrating the data to attacker-controlled infrastructure.

The malware strains, called MOAAZDROID and LOVELYDROID, are the handiwork of the Hamas-affiliated actor DESERTVARNISH, which is also tracked as Arid Viper, Desert Falcons, Renegade Jackal, and UNC718. Details about the spyware were previously documented by Cisco Talos in October 2023.

State-sponsored groups from Iran, such as MYSTICDOME (aka UNC1530), have also been observed targeting mobile devices in Israel with the MYTHDROID (aka AhMyth) Android remote access trojan as well as a bespoke spyware called SOLODROID for intelligence collection.

“MYSTICDOME distributed SOLODROID using Firebase projects that 302-redirected users to the Play store, where they were prompted to install the spyware,” said Google, which has since taken down the apps from the digital marketplace.

Google further highlighted an Android malware called REDRUSE – a trojanized version of the legitimate Red Alert app used in Israel to warn of incoming rocket attacks – that exfiltrates contacts, messaging data, and location. It was propagated via SMS phishing messages that impersonated the police.

The ongoing war has also had an impact on Iran, with its critical infrastructure disrupted by an actor named Gonjeshke Darande (meaning Predatory Sparrow in Persian) in December 2023. The persona is believed to be linked to the Israeli Military Intelligence Directorate.

The findings come as Microsoft revealed that Iranian government-aligned actors have “launched a series of cyberattacks and influence operations (IO) intended to help the Hamas cause and weaken Israel and its political allies and business partners.”

Redmond described their early-stage cyber and influence operations as reactive and opportunistic, while also corroborating with Google’s assessment that the attacks became “increasingly targeted and destructive and IO campaigns grew increasingly sophisticated and inauthentic” following the outbreak of the war.

Beside ramping up and expanding their attack focus beyond Israel to encompass countries that Iran perceives as aiding Israel, including Albania, Bahrain, and the U.S., Microsoft said it observed collaboration among Iran-affiliated groups such as Pink Sandstorm (aka Agrius) and Hezbollah cyber units.

“Collaboration lowers the barrier to entry, allowing each group to contribute existing capabilities and removes the need for a single group to develop a full spectrum of tooling or tradecraft,” Clint Watts, general manager at the Microsoft Threat Analysis Center (MTAC), said.

Last week, NBC News reported that the U.S. recently launched a cyber attack against an Iranian military ship named MV Behshad that had been collecting intelligence on cargo vessels in the Red Sea and the Gulf of Aden.

An analysis from Recorded Future last month detailed how hacking personas and front groups in Iran are managed and operated through a variety of contracting firms in Iran, which carry out intelligence gathering and information operations to “foment instability in target countries.”

“While Iranian groups rushed to conduct, or simply fabricate, operations in the early days of the war, Iranian groups have slowed their recent operations allowing them more time to gain desired access or develop more elaborate influence operations,” Microsoft concluded.
