Cyber threat actors associated with the Cyclops ransomware have been observed offering an information stealer malware designed to capture sensitive data from infected hosts. The threat actor behind this Ransomware-as-a-Service (RaaS) promotes its offering on forums where it requests a share of profits from those engaging in malicious activities using its malware.
Cyclops ransomware is notable for targeting all major desktop operating systems, including Windows, macOS, and Linux. It is also des
In late January, a new botnet campaign was discovered targeting unpatched software running on Linux devices with recent code execution CVEs. Once a device is compromised, the bot downloads and executes a malicious Python script that joins the compromised device to the botnet. The botnet is controlled by attackers using Internet Relay Chat (IRC) and enables the attackers to perform DDoS attacks and run crypto miner software on infected devices. Updates are available to patch all CVEs exploited
