QUOTE: Twitter was shut down for hours Thursday morning by what it described as an ongoing denial of service attack. In a one sentence statement on its status blog, Twitter said, “We are defending against a denial-of-service attack, and will update status again shortly.” The outage appeared to begin mid-morning, EST, and affected users around the world.
When Windows or other software products experience a fatal crash they cannot recover from, it is termed as a "Blue Screen of Death" (BSOD). This latest attack simulates a BSOD and offers users a fake cleanup tool to fix the BSOD condition (after paying usually $39). Anyone infected must use a true AV product or standalone cleaning tool instead to remove this harmful software.
