Linux under attack: Compromised SSH keys lead to rootkit

Filed under
Linux
Security

The U.S. Computer Emergency Readiness Team (CERT) has issued a warning for what it calls “active attacks” against Linux-based computing infrastructures using compromised SSH keys.

The attack appears to initially use stolen SSH keys to gain access to a system, and then uses local kernel exploits to gain root access. Once root access has been obtained, a rootkit known as "phalanx2" is installed, US-CERT said in a note on its current activity site.

Phalanx, which dates back to 2005, is a self-injecting kernel rootkit designed for the Linux 2.6 branch. It allows an attacker to hide files, processes and sockets and includes a tty sniffer, a tty connectback-backdoor, and auto injection on boot.

Huawei CEO: Will keep using Android as long as it's open

He made the said comment in a Weibo post, where-in he also noted that Google's mobile OS has promoted the development of smartphones, which in turn has benefited consumers. Interestingly, he didn't say anything about whether or not Huawei is developing an in-house mobile OS - said to be called Kirin OS. His silence on the matter, though, can be taken as a confirmation of sorts, especially when his comment reflects the possibility of Google restricting the companies’ freedom with Android in future.
