# Intro
In a shocking revelation, a stealthy Linux malware named “perfctl” has been exploiting server vulnerabilities for over three years, using advanced evasion techniques to secretly mine Monero cryptocurrency on countless systems worldwide. This elusive threat not only disrupts normal operations by maxing out CPU usage but also deftly vanishes when users log in, making detection extremely difficult for many administrators.
How do adversaries exploit vulnerabilities to gain initial access to systems with the perfctl malware?
Hackers are actively exploiting a critical SQL injection flaw in Ivanti Endpoint Manager, prompting US federal agencies to rush and remediate the threat by October 23, 2024. Despite Ivanti’s urgent patches, details of the attacks remain sparse, spotlighting the pressing need for effective cybersecurity measures.
Why does this particular vulnerability pose such a significant risk compared to others?
North Korean APT group Stonefly, undeterred by legal indictments, is intensifying its financially-motivated cyberattacks on US companies, leveraging a unique arsenal of malware and tools. Despite failed ransomware attempts, their distinctive Preft backdoor confirms their tenacity in pursuing targets with no direct intelligence value.
Why has Stonefly shifted their focus from espionage to financially-driven cybercrime in recent years?
A staggering rise in stolen cloud credentials is fueling an underground market of AI-powered sex chat services, with cybercriminals bypassing content filters for disturbing role-plays involving child sexual exploitation. As security researchers lay bare the chilling implications of compromised AI infrastructure, the industry scrambles for solutions to thwart this escalating threat.
**Question:** How are cybercriminals leveraging stolen cloud credentials to evade content restrictions on AI, and what are the financial and ethical implications for the victims?
# Stories
In this episode, we discuss a recent discovery by Aqua Nautilus researchers of the Linux malware “perfctl,” which has been running a covert cryptomining campaign for over three years. This malware has targeted potentially millions of Linux servers, using advanced evasion techniques and rootkits to remain largely undetected. Perfctl primarily uses compromised servers to mine the Monero cryptocurrency, exploiting misconfigurations and vulnerabilities, such as CVE-2023-33246 in Apache RocketMQ and CVE-2021-4034 in Polkit, for initial access. It operates stealthily, disguising processes and using TOR for encrypted communications.
The malware also deploys proxy-jacking software for additional revenue streams. System administrators often notice infections due to 100% CPU usage, though perfctl halts its activities as soon as the user logs in. Due to its evasive and persistent nature, typical removal methods are ineffective, with a full system wipe and reinstall recommended to ensure complete removal. Aqua Nautilus suggests monitoring system directories, CPU usage, and network traffic, alongside patching known vulnerabilities, to detect and prevent perfctl infections.
