The group, which calls itself Anonymous, said it will launch the attack at 7.30pm GMT on Wednesday (3.30am Thursday Malaysian time) and has named it “Operation Malaysia.”
It posted the threat in a graphic on this website, http://i.imgur.com/PTFWh.png.
Mikko Hypponen, chief research officer at the F-Secure Corporation – a computer security software company based in Helsinki, Finland – tweeted about the threat at 4.42am Malaysian time.
No other details were available at this time. It is also not known why Anonymous has targeted the Malaysian website.
Hacker group Anonymous threatens to attack Malaysian Government website.
But there has been an uptick in “hacktivism” these past weeks, where hacker groups have targeted various organisations for political purposes.
Hackers have attacked the International Monetary Fund and Sony PlayStation Network, as well as the networks of aeronautics company Lockheed Martin Corp and Citibank in North America, amongst others.
Anonymous was blamed for the hack into the PlayStation network but a spokesman for the group has denied involvement, saying that its aims are political. Spain, however, has arrested three suspected members of the hacker group for that attack.
Anonymous apparently comprises a vast number of hackers in various countries, who have been organised into cells that share common goals. They operate anonymously but in a co-ordinated fashion.
More details to follow.
Meanwhile the AP reported from New York that a group of hackers has gained access to the websites of the U.S. Senate and video game company Bethesda Softworks, the latest in a series of cyberattacks plaguing a broad range of online victims.
The group, which calls itself Lulz Security, posted what it called a “small, just-for-kicks release of some internal data” from Senate.gov on its website on Monday.
Likely referencing reports that the Pentagon is considering whether a cyberattack could be considered an act of war, the group also wrote “is this an act of war, gentlemen? Problem?”
