February 2, 2011 - Update:

Just another evidence of the sourceforge breach used by a web bot. At least , from the following screenshot, seems that the entrypoint was detected by a web vuln scanner bot. The following figure shown a well known method by web bots to post in some pastebin clone web site the result of their work.

This pastie was released at the end of 2010. The bad thing is that OFF keyword tell to bots admin that php_safe is OFF

The problem is that this breach, if confirmed, can be exploited to modify source code so as to fail the trust levels of applications mantained by this software repository.


  1. Hehe you have hidden the sourceforge link on your webbot screenshot but not the other vulnerable websites. :-)

    In my honeypot logs, I see at least 5 sourceforge accounts that seems hackable and used as an entry point.
