PHP.net breach: Concern over safety of source code
Maintainers of the PHP programming language spent the past few days scouring their source code for malicious modifications after discovering the security of one of their servers had been breached.
The compromise of wiki.php.net allowed the intruders to steal account credentials that could be used to access the PHP repository, the maintainers wrote in a brief note. They continue to investigate details of the attack, which exploited a vulnerability in the Wiki software and a separate security flaw in Linux. The site has been down since at least Friday.
