Linux Worm Targeting Hidden Devices

Created: 27 Nov 2013 11:53:48 GMT | Translations available: 日本語

Symantec has discovered a new Linux worm that appears to be engineered to target the “Internet of things”. The worm is capable of attacking a range of small, Internet-enabled devices in addition to traditional computers. Variants exist for chip architectures usually found in devices such as home routers, set-top boxes and security cameras. Although no attacks against these devices have been found in the wild, many users may not realize they are at risk, since they are unaware they own devices that run Linux.

The worm, Linux.Darlloz, exploits a PHP vulnerability to propagate itself in the wild. The worm utilizes the PHP 'php-cgi' Information Disclosure Vulnerability (CVE-2012-1823), which is an old vulnerability that was patched in May 2012. The attacker recently created the worm based on the Proof of Concept (PoC) code released in late Oct 2013.

Upon execution, the worm generates IP addresses randomly, accesses a specific path on the machine with well-known ID and passwords, and sends HTTP POST requests, which exploit the vulnerability. If the target is unpatched, it downloads the worm from a malicious server and starts searching for its next target. Currently, the worm seems to infect only Intel x86 systems, because the downloaded URL in the exploit code is hard-coded to the ELF binary for Intel architectures
