Subject: fragrouter trojan On October 18, www.anzen.com was compromised and a trojan was placed at http://www.anzen.com/archive/research/fragrouter-1.7.tar.gz MD5 (fragrouter-1.7.tar.gz) = 8329c34704287a1fb1e5d6f1ba81f456 After being notified by Hank Leininger on October 19, it was subsequently removed. This release of fragrouter 1.7 is COMPLETELY BOGUS. fragrouter has not been actively maintained for 3 years (1.6 being the last proper release), and has since been obsoleted by fragroute. The attacker even went to the lengths of creating a fake CHANGELOG entry, but only adding the trojan code. The trojan itself is very similar to those recently found in irssi, fragroute, BitchX, OpenSSH, and Sendmail. Embedded in the configure script is a C program that will remotely bind a shell. An interesting addition to this version is that it will dynamically decide which IP address in which to connect the shell by grabbing text from a URL, in this case: http://www.anzen.com/images/anzen-title_r3_f2_c4.jpg Contained in this file is the string 'IPDATA210.224.164.100', so it would connect to TCP port 6667 on 210.224.164.100. The owner has been contacted and this port is currently closed. Thanks again to Hank for the initial analysis. The attacker then tried to bait both the linux-kernel & cisco-nsp lists: http://marc.theaimsgroup.com/?l=cisco-nsp&m=103515530331228&w=2 http://marc.theaimsgroup.com/?l=linux-kernel&m=103505549207211&w=2 Attached is a complete diff against a known-good copy of fragrouter-1.6. Two things of note: 1) Some of the previous trojans responded to the commands 'A', 'D', & 'M' over port 6667, but this one uses 'B', 'G', & 'K'. 2) Included in the trojan is the string: # íéì.Ê
