Malware on Facebook[1], a term that refers to various forms of harmful software aimed at Facebook users, is a significant issue. It encompasses a rise in phishing attacks seen predominantly in the 2010s and the use of misleading URLs to fool users. Key instances include the propagation of the Dorkbot malware strain via Facebook’s chat feature in 2013 and the Koobface worm’s spread through Facebook and MySpace in 2008. In response to these threats, Facebook has employed grey hat[2] hackers like George Hotz and launched a Bug Bounty Program in 2011, offering rewards for reporting security vulnerabilities. The social media giant has also deactivated accounts associated with state-backed malware, including those controlled by North Koreans. The fight continues to specifically target and combat users participating in malware attacks.
The social media platform and social networking service Facebook has been affected multiple times over its history by intentionally harmful software. Known as malware, these pose particular challenges both to users of the platform as well as to the personnel of the tech-company itself. Fighting the entities that create these is a topic of ongoing malware analysis.
