Email Security through Procmail 1.137 - Email Security through Procmail attempts to address the trend towards "enhancing" email clients with support for active content, which exposes end-users to many and varied threats, by "sanitizing" email: removing obvious exploit attempts and disabling the channels through which exploits are delivered. Facilities for detecting and blocking Trojan Horse exploits and worms are also provided.

33f0ab9cc7a39a816dbc6dddc8b1952feeb6871f5ad68e60decab4626431eb7cSOFFIC is a Linux kernel patch for kernel 2.4.18 that provides file integrity control integrated into the normal system operation, on-the-fly. It checks a file's integrity each time a monitored file is opened for reading or execution, and issues a warning if it is found to be invalid. It protects against rootkits, backdoors, worms, viruses, Web defacement, unauthorized installation and use of new software, and much more.

05c175a604896782e0fcbcd14dc4dd9717f3a58ec9ab6bcd61c01732daafaeadThis is a modified version of the Slapper worm and was recovered from a compromised machine. Modifications to the worm let it mail system information, such as the ip address and processor type, to a Yahoo! email address. No other changes where made.
d871493127f042e44746b0d6678a391feb86eed4b2f5224af756399b4ec22188This exploit abuses the KEY_ARG buffer overflow that exists in SSL enabled Apache web servers that are compiled with OpenSSL versions prior to 0.9.6e. The apache-ssl-bug.c exploit is based on the Slapper worm (bugtraq.c), which is based on a early version of the apache-open-ssl exploit.

It exploits an OpenSSL buffer overflow to run a shell on the remote system and also contains the ability to perform a DDoS attack. These files were found in the wild from machines that had been compromised.

The worm scans for vulnerable systems on port 80, then sends exploit code over port 443. The worm also functions as a ddos network which communicates over TCP port 2002. Infected systems can be identified by the presence of /tmp/.bugtraq.c. Fix available here.

afa39a9760405916c858cb5d59fb655636e8a1996d513a5e5b09ef0572337eadBigeye is a network utility dump that can be run in multiple modes - sniffer, logging connections, and even emulating protocols such as HTTP or FTP. The main focus of this program is to create an emulative service that would fool hackers/worms into thinking that they're exploiting a real service, but in fact, they're trying to exploit a fake service. The services currently available are ftp or http. Useful for honeypots.
