BPFDoor Strikes Again: New Cyber Threat Unleashes Havoc on Global Networks!
Cybersecurity researchers have discovered a new BPFDoor controller component targeting sectors in South Korea, Hong Kong, and more. This Linux backdoor, a spy tool since 2022, exploits Berkeley Packet Filter technology. Earth Bluecrow’s campaign has identified a covert channel enabling attackers to control compromised systems and access sensitive data over time.
Hot Take:
Who would’ve thought a backdoor could be as persistent as that one friend who always shows up uninvited? BPFDoor is like the ultimate party crasher, sneaking past firewalls and making itself at home in your servers. What’s next, BPFDoor asking for a Wi-Fi password and Netflix suggestions?
Key Points:
- Researchers discovered a new controller component linked with BPFDoor backdoor.
- BPFDoor targets sectors like telecommunications, finance, and retail in various countries.
- Operates by creating covert channels to control compromised devices and access sensitive data.
- Uses Berkeley Packet Filter (BPF) to bypass firewalls and trigger the backdoor.
- Employs a password-protected controller for executing commands on infected systems.
