In 2003, the Fizzer worm took advantage of the growing peer-to-peer file-sharing trend, spreading across Kazaa and beyond. What seemed like a harmless music download on Limewire could turn into a backdoor for hackers. In this episode of In The Shell, I share my personal experience with file sharing on my Blue Dell Inspiron 1100 and how I unknowingly encountered malware for the first time. We’ll explore the origins of the Fizzer worm, its unique ability to auto-update, disable antivirus software, and install keyloggers to steal personal information.
I’ll explain how Fizzer spread through file-sharing platforms and network shares, how it spoofed emails, and the sophisticated techniques it used to stay one step ahead of antivirus programs. From peer-to-peer networks to corporate environments, Fizzer’s reach was global—and the impact on users was profound.
