๐Ÿ”’๐Ÿ–ฅ๏ธ Watch Out: Raspberry Robin Malware Gets Stealthier! ๐Ÿ›‘

Raspberry Robin, the notorious malware family known for facilitating initial access to other malicious payloads, has upped its game with two new one-day exploits for local privilege escalation. ๐Ÿ˜ฑ Check Point's recent report reveals that these exploits are used shortly after being developed, suggesting access to an exploit seller or rapid in-house development.

This evasive malware, attributed to the threat actor Storm-0856, has been on the radar since 2021 and is part of a complex malware ecosystem with ties to prominent e-crime groups like Evil Corp and Silence. ๐Ÿ˜ก It spreads through various vectors, including infected USB drives, acting as a gateway for ransomware and other threats.

What's alarming is Raspberry Robin's use of undisclosed exploits, like CVE-2023-36802, which was advertised on the dark web months before it was publicly disclosed and patched by Microsoft. ๐Ÿ˜จ These exploits are integrated quickly into the malware's arsenal, posing a significant threat to organisations that may not have applied patches.

To make matters worse, the malware now utilises rogue RAR archive files hosted on Discord to gain initial access and has tweaked its lateral movement and C2 communication methods for increased stealth. ๐Ÿ•ต๏ธโ€โ™‚๏ธ This includes switching from PsExec.exe to PAExec.exe for lateral movement and dynamically selecting V3 onion addresses for C2 communication.

Incorporating these changes, Raspberry Robin continues to evolve, making it more challenging to detect and analyse. Vigilance and timely patching remain crucial in defending against such sophisticated threats! ๐Ÿ›ก๏ธ

๐Ÿšจ๐Ÿ”’ Islamic Non-Profit in Saudi Arabia Targeted by Stealthy Cyber Espionage Campaign! ๐Ÿ’ป๐Ÿ”

An unnamed Islamic non-profit organisation in Saudi Arabia has fallen victim to a sophisticated cyber espionage campaign, where threat actors deployed a previously undocumented backdoor named Zardoor. ๐Ÿ˜ฑ Discovered by Cisco Talos in May 2023, the campaign likely began as early as March 2021 and has flown under the radar, with only one known target identified so far.

Throughout the operation, the attackers utilised living-off-the-land binaries (LoLBins) to maintain long-term access to victim environments discreetly, avoiding detection. ๐Ÿ•ต๏ธโ€โ™‚๏ธ The attack on the Islamic charity involved periodic data exfiltration, with the initial access vector still shrouded in mystery.

Zardoor, the stealthy backdoor deployed for persistence, is orchestrated using open-source reverse proxy tools like FRP, sSocks, and Venom to establish command-and-control connections. ๐Ÿ›ก๏ธ Leveraging Windows Management Instrumentation (WMI) for lateral movement, the threat actor spreads Zardoor across the network, executing commands received from the C2.

The infection pathway involves a dropper component that instals a malicious dynamic-link library ("oci.dll"), unleashing two backdoor modules, "zar32.dll" and "zor32.dll." While "zar32.dll" handles C2 communications, "zor32.dll" ensures administrator privileges for the backdoor. ๐Ÿ˜จ Zardoor's capabilities include data exfiltration, remote execution, IP address updates, and self-deletion.

Despite extensive analysis, the identity and motives of the threat actor remain unknown, with no discernible ties to known cybercriminal groups. ๐Ÿ•ต๏ธโ€โ™€๏ธ The sophistication and stealthiness of the operation indicate the work of an advanced threat actor, posing a significant challenge to detection and mitigation efforts.

Organisations must remain vigilant and bolster their cybersecurity defences against such stealthy and persistent threats! ๐Ÿ›ก๏ธ๐Ÿ”

๐Ÿ›‘โš ๏ธ U.S. Justice Department Seizes Online Infrastructure Selling Warzone RAT โš ๏ธ๐Ÿ›‘

In a significant move, the U.S. Justice Department (DoJ) has seized online infrastructure linked to the sale of a notorious remote access trojan (RAT) dubbed Warzone RAT. ๐Ÿšจ The domains, including www.warzone[.]ws, were utilised to peddle this malicious software, allowing cybercriminals to clandestinely access and pilfer data from victims' computers.

In a coordinated international effort, law enforcement has apprehended and indicted two individuals in Malta and Nigeria for their roles in promoting and facilitating the use of the malware. ๐Ÿ‘ฎโ€โ™‚๏ธ๐Ÿ‘ฎโ€โ™€๏ธ Daniel Meli (27) and Prince Onyeoziri Odinakachi (31) face charges related to unauthorised access to protected computers, with Meli additionally accused of illegally vending electronic interception devices and conspiring to commit computer intrusion offences.

Meli, operating since 2012, has a history of providing malware services through online forums, including his previous sale of the Pegasus RAT. Odinakachi, on the other hand, provided customer support for Warzone RAT purchasers between June 2019 and March 2023.

Warzone RAT, also known as Ave Maria, operates under the malware-as-a-service (Maas) model, enabling threat actors to steal information and remotely control infected hosts for further exploitation. ๐Ÿ•ต๏ธโ€โ™‚๏ธ Sold for $38 a month, its functionalities include browsing victim file systems, capturing screenshots, recording keystrokes, stealing credentials, and activating webcams without consent.

The FBI, in collaboration with international partners, covertly acquired copies of Warzone RAT, confirming its malicious capabilities. ๐Ÿ•ต๏ธโ€โ™€๏ธ This joint effort involved authorities from Australia, Canada, Croatia, Finland, Germany, Japan, Malta, the Netherlands, Nigeria, Romania, and Europol.

The dismantling of the Warzone RAT infrastructure marks a significant victory in the ongoing battle against cybercrime, demonstrating the effectiveness of global cooperation in combating online threats. ๐Ÿค Organizations are urged to remain vigilant and enhance their cybersecurity measures to safeguard against such malicious activities. ๐Ÿ›ก๏ธ๐Ÿ”’
