Some 17,000 email addresses and passwords from US government and military sources have been stolen and dumped on a public cyberlocker.
A hacking group calling itself the Connexion Hack Team published a list of email addresses linked to the US military, the National Security Agency, Department of Homeland Security, and multiple state government agencies.
The group did not disclose the source of the information, a stance taken by many participants of the Anti-Security movement.
“These [accounts] are random and do not ask which website they came from,” the group posted in a statement.
“We want everyone to know that we mean business here.”
Passwords were withheld from the "important accounts", including the military email domains, but they were published for reams of accounts posted from providers Yahoo, Gmail, MSN, Verizon and Hotmail among others.
The dump comes after the group published what appeared to be the website contents of the California Fair Political Practices Commission on Monday.
Connexion said in a tweet after the hack that it is establishing a website and is recruiting members.
It proposed candidates hack its site with the winner getting a spot on the team.
“We need a new member on the team, so our idea is the person who hacks our website gets to be on the team,” it said.
