Anonymous, the hacker collective, has released the log-in info, phone numbers and other personal information of more than 4,000 bank executives in a leak that is part of "Operation Last Resort."
Called "doxing" or "to dox," the hacker term means releasing personally identifiable information on the Internet.
The group tweeted a spreadsheet containing the information which was posted on the .gov website of Alabama Criminal Justice Information Center. They created a custom link to the document with the phrase "oops-we-did-it-again."
Operation Last Resort is a campaign to avenge the death of Aaron Swartz, a Harvard researcher known for his contributions to RSS and Reddit. He committed suicide after he was charged with multiple crimes, including wire fraud, after he illegally downloaded thousands of academic articles from a service called JSTOR.
Anonymous believes outdated computer crime laws and "overzealous prosecution" led to his suicide.
This leak comes a week after the group turned the United States Sentencing Commission site into a game of Asteroids.
They might have released the information to coincide with Attorney General Eric Holder's deadline for answering questions about Swartz's prosecution.
A week ago, a House panel gave a letter to Holder which demanded answers about his prosecution. There were seven specific questions, and Holder had until today to respond.
Operation Last Resort's YouTube video has now garnered more than one million views.
