Notorious Internet hacking group Anonymous, that stole thousands of credit card numbers from an American security firm Stratfor, have now published the email addresses of over 860,000 of its clients.
Anonymous released the data, including information on former US Vice President Dan Quayle and former Secretary of State Henry Kissinger, online.
The lists of emails included scrambled details of their passwords, which according to experts, could be cracked within a matter of seconds by using software downloaded for free, the Daily Mail reports.
A spokesperson for the group said via Twitter that yet to be published emails from the firm would show that Stratfor, which gathers non-classified intelligence on international crises, 'is not the 'harmless company' it tries to paint itself as'.
In a posting on the data-sharing website pastebin.com, the hackers said the list included information from about 75,000 customers of Stratfor and about 860,000 people who had registered to use its site.
It said that included some 50,000 email addresses belonging to the US government's .gov and .mil domains.
The list also included addresses at contractors including BAE Systems Plc, Boeing Co, Lockheed Martin Corp and several US government-funded labs.
Stratfor issued a statement on Friday confirming that the published email addresses had been stolen from the company's database, saying it was helping law enforcement probe the matter and conducting its own investigation. (ANI)
