I’m sorry to report that one of the important servers of the Frugalware infrastructure was compromised on August 25. It took a while to find out the details of how that was possible, read here if you’re interested.
In short: we found that the attacker installed a backdoor similar to the one installed on kernel.org recently. We have already reinstalled the operating system, plus taken steps to prevent a similar attack in the future.
On the bright side, we verified that none of the Frugalware Git repos nor binary packages were modified during the attack, so you don’t have to fear that Pacman-G2 installed any problematic updates on your computer.
Thanks for your understanding.
