Despite a ransomware payment controversy, some companies still decide to yield to the attacker’s requests. Doing so may seem like the easiest way out, but it comes with its own set of complications, both ethical and legal.

Stealer logs and the infostealers that harvest them form a key part of the threat landscape and cybercriminal ecosystem. Infostealers, which are also referred to as stealer malware, are deployed by threat actors to facilitate data theft from compromised devices. This data typically contains sensitive and valuable personal information including credentials, hardware or software information, IP addresses, browser cookies, and more.

DLL side-loading is a popular technique used by threat actors to execute malicious payloads under the umbrella of a benign, usually legitimate, executable. This allows the threat actor to exploit whitelists in security products that exclude trusted executables from detection. Among others, this technique has been leveraged by APT41 to deploy DUSTTRAP and Daggerfly to deliver Nightdoor backdoor.

In December 2024, Arctic Wolf Labs observed a mass exploitation campaign involving Cleo Managed File Transfer (MFT) products for initial access. The execution chain involved an obfuscated PowerShell stager, a Java loader, and ultimately a Java-based backdoor, which we will refer to as Cleopatra. In this article we will provide insight into the execution chain in this campaign, obfuscated malicious payloads deployed, and surrounding threat intelligence context around these activities.

Did you know that 59% of organizations have been hit by ransomware, with Active Directory (AD) often being the primary target for attackers seeking credential theft and privilege escalation? With AD being basically the heart of enterprise IT from the permissions management and granting view, these ransomware threats automatically go against it and hence protecting them is pretty much important so to keep the organization safe.

MacOS, often regarded for its robust security measures, has increasingly become a target for sophisticated cyber threats. Among the latest examples is Banshee Stealer, a malware engineered to compromise macOS systems by extracting sensitive user information. Developed by Russian cybercriminals and offered at a premium subscription fee of $3,000 per month, this malware underscores the growing attention of threat actors toward macOS platforms.

Another week, another extortion group data-leak site emerges. Cyjax has continued to observe the emergence of data-leak sites (DLSs) for extortion and ransomware groups. New groups FunkSec, ContFR, Argonauts, Kairos, Chort, and Termite appeared in December and November 2024 alone, bringing this year’s total up to 69. On 11 December 2024, Cyjax identified the emergence of a Tor-based DLS belonging to a new data-leak extortion group going by the name ’Bluebox’.
