Linux worm turns on Mambo and PHP
Security experts today warned of a Linux network worm that exploits holes in the Mambo content management system and the PHP XML-RPC library.
Dubbed Mare.D, the worm leaves multiple backdoors on infected systems. Two of these are connectback shell backdoors that link to a remote host, while a third allows the malware's writer to access and control infected systems via IRC.
"The main component of the Mare.D worm is written in C and compiled with the GNU C compiler," said F-Secure researcher Gergely Erdelyi. The worm scans for vulnerable systems automatically and installs a small shell script which downloads the rest of the malware.
