PETALING JAYA (TheStar / ANN): After being inactive for nearly six years, a hacker activist group claiming to be Anonymous Malaysia said it will launch attacks on Malaysian government websites soon. The attack will be a “wake-up call,” the group said in one Facebook post, which demands that the government do more to prevent data breaches. In its online video, the group claimed that the “government security system is low” and that “all data can be leaked”, allowing unwanted hackers to sell the information.
