WordPress.com, one of the most popular blog service, experienced security incidents. Some of their servers compromised.

It is spoken by the founder of WordPress, Matt Mullenweg, in his official blog. “Automattic (the company behind WordPress), so victims of burglary low-level or root in some of our servers,” writes Matt, as quoted DailyLog, Thursday (14/04/2011).

According to him, there is the possibility of any existing data on a server that has successfully accessed by the offender.

“We’re researching and reviewing logs and records the data from it to see the extent to which information is exposed, and we secure the re-used paths,” he said.

Matt estimate the source code that is in the server that has been copied. Although WordPress is Open Source, Matt said there are things in the server of sensitive Automattic code and partners.

Matt’s suggestion for users of WordPress, as he wrote, is just what they had previously suggested. This includes strengthening passwords, use different passwords for every site you use and change the password that is still the same.

“Our investigation is still ongoing and takes time. As I’ve said, we took decisive steps to prevent similar incidents in the future,” he insisted.
