Recently, a new cyber threat known as “Fireball” has surfaced. While perhaps not malware in the traditional sense we expect, the potential threat is immense when leveraged maliciously. Fireball seemingly manipulates the victim computer in the interest of generating ad revenue but these modifications, while annoying, may lead to far more sinister behaviour in the future leveraging backdoors. Imagine the potential personal and corporate data harvesting and capability of launching large-scale attacks. Immediately seek and remove freeware on personal and business computers, conduct thorough threat scans, and block network traffic to the known command and control servers as a start.
