Although the event appears to be somewhat haphazard, if successful, Anonymous could take down government and oil-company sites in North America, Europe and Asia.

#OpPetrol is scheduled to take place today (June 20), although as of right now, no major sites appear to be compromised in any way. Anonymous generally attacks with a distributed denial of service (DDoS) maneuver, which crashes websites by overwhelming them with fake visits.

Although #OpPetrol has hacked a few small sites by posting its logo and mission statement on the sites' home pages, repairs are already underway. Of the sites reported compromised by Hackers News Bulletin, most are up and running just fine, with minimal slowdown.
