The Friday hacks appeared to compromise emails and other sensitive documents:

A web page that included Anonymous' signature tag line stated the hacking was in response to Alabama's "recent racist legislation in an attempt to punish immigrants as criminals" -- referring to legislation, signed last June, aimed at cracking down on illegal immigration in the state.

The Anonymous-related Twitter page also provided links to documents, messages and other files that it said it had taken off a website tied to Mexico's mining ministry.

"Hello Mexican Chamber of Mines," a related Twitter post read. "Want to see your emails exposed?"

Interpol's website, Interpol.int, was hit Saturday afternoon:

Yep, seems INTERPOL (interpol.int ) is still Tango Down from here - downforeveryoneorjustme.com/http://www.int… (via @BlackTuesday) #Anonymous

A message found on Pastebin.com appeared to imply credit for DDoSing Interpol and was tagged "With love from @blackTuesday." (Ed: The Twitter handle for the group is apparently @BlackTuesdayHG.)

Thousands protested A.C.T.A. (Anti-Counterfeiting Trade Agreement) across Europe on Saturday. While anti-piracy A.C.T.A. is a favorite target for Anonymous's wrath and plenty of Guy Fawkes masks were in evidence in photos of protesters, it wasn't clear that the Interpol wipe and A.C.T.A. protests were connected.
