Automattic and WordPress founder Matt Mullenweg announced today that theirservers have been hacked, and source code compromised. Specifically, Automattic had a "low-level (root) break-in” to several servers. He said that "potentially anything on those servers could have been revealed.”
"We have been diligently reviewing logs and records about the break-in to determine the extent of the information exposed, and re-securing avenues used to gain access,” said Mullenweg. "We presume our source code was exposed and copied. While much of our code is Open Source, there are sensitive bits of our and our partners’ code. Beyond that, however, it appears information disclosed was limited.”
The only advice he had for users was to use a secure password. So you might want to consider changing yours.
According to TechCrunch, "site source code includes API keys and Twitter and Facebook passwords which can let interested parties gain access to sensitive information as well as shut people out of their Twitter and Facebook accounts, etc.”
