“Canadian security agencies have warned energy companies such as Imperial Oil their computers may be attacked by the hacker group Anonymous because of the industry’s work developing Alberta’s oilsands, government documents show.
The RCMP, public safety department and Communications Security Establishment Canada all investigated threats against the industry between the start of 2011 and mid-March, according to documents obtained this month by Bloomberg News under freedom of information laws. The RCMP conducted a threat assessment after Anonymous issued a press release in July 2011 accusing oilsands companies of being greedy and harming the environment.”
