It wasn't a particularly heinous hack.
On Friday, the BPD brought the site back up, and brought it up with a vengeance, a humorous one. Not only did they bring the site back up, they produced a video to make fun of themselves. We'd guess this won't sit too well with Anonymous.
A voiceover said, “In the days after the hacking, fans of the page struggled to make sense of a world without BPDnews.com."
Lydon added that “Normally I sleep pretty well. But since the site went down, I haven’t slept a wink."
One officer said in Spanish, "I miss being able to read the site in 36 different languages."
The BPD was quite clear that the site is now safe. They asked the IT adminstration "Are you confident the issue has been addressed?" To that, he answered, "I'm confident the issue has been addressed."
As they video noted, though, there's no guarantee the site is up for good. Especially if Anonymous doesn't take kindly to the video. On the other hand, after the New England Patriots lost the Super Bowl, the city could use a good laugh.
