Editing TCP Wrappers (section)

==1999 Trojan==
In January 1999, the distribution package at [[Eindhoven University of Technology]] (the primary distribution site until that day) was replaced by a modified version. The replacement contained a trojaned version of the software that would allow the intruder access to any server that it was installed on. The author spotted this within hours, upon which he relocated the primary distribution to his personal site.<ref>{{cite web |title=CERT Advisory CA-1999-01 Trojan horse version of TCP Wrappers |url=https://resources.sei.cmu.edu/asset_files/WhitePaper/1999_019_001_496184.pdf#page=5 |website=Carnegie Mellon University Software Engineering Institute |archive-url=https://web.archive.org/web/20001017170613/http://www.cert.org/advisories/CA-1999-01.html |archive-date=2000-10-17 |access-date=15 September 2019 |url-status=live}}</ref><ref>{{cite web |title=CERT Advisory CA-1999-02 Trojan Horses |url=https://resources.sei.cmu.edu/asset_files/WhitePaper/1999_019_001_496184.pdf#page=14 |website=Carnegie Mellon University Software Engineering Institute |archive-url=https://web.archive.org/web/20001017172300/http://www.cert.org/advisories/CA-1999-02.html |archive-date=2000-10-17 |access-date=15 September 2019 |url-status=live}}</ref><ref>[http://seclists.org/bugtraq/1999/Jan/0257.html ''backdoored tcp wrapper source code'', by Wietse Venema], on [[Bugtraq]], Jan 21, 1999</ref><ref>[http://seclists.org/bugtraq/1999/Jan/0314.html ''Announcement: Wietse's FTP site has moved'', by Wietse Venema], on [[Bugtraq]], Jan 21, 1999</ref>
