ILOVEYOU, also known as the “Love Letter” worm, is one of the most infamous computer worms in the history of cybersecurity. It wreaked havoc on computer systems worldwide, causing extensive damage and financial losses when it emerged in May 2000. The worm propagated itself via email and affected millions of computers across the globe. This article delves into the history, structure, key features, types, and implications of ILOVEYOU, shedding light on its impact on the digital landscape.
The History of the Origin of ILOVEYOU and the First Mention of It
ILOVEYOU was created by two Filipino computer science students, Reonel Ramones and Onel de Guzman, who studied at the AMA Computer College in the Philippines. The worm first emerged on May 4, 2000, and quickly spread via email in the form of an attachment named “LOVE-LETTER-FOR-YOU.txt.vbs.” Disguised as a love letter, the attachment lured unsuspecting users into opening it. Once executed, the worm would overwrite files, steal user credentials, and propagate itself by sending infected emails to all contacts in the victim’s address book.
Detailed Information about ILOVEYOU
ILOVEYOU was written in Visual Basic Script (VBS), making use of Microsoft Outlook’s security vulnerabilities to spread rapidly. The worm targeted computers running the Microsoft Windows operating system, especially Windows 95, 98, and NT. It utilized social engineering techniques, preying on users’ curiosity by enticing them to open the attachment with subject lines like “ILOVEYOU” or “Love Letter for You.”
The Internal Structure of ILOVEYOU and How It Works
When a user opened the infected attachment, the ILOVEYOU worm activated a chain of destructive events. It first copied itself to the Windows directory under the name “MSKernel32.vbs” to ensure its persistence on the system. Next, it modified the Windows registry to ensure automatic execution on system startup. The worm proceeded to overwrite various file types, including images, music, and documents, effectively destroying them.
Moreover, ILOVEYOU scanned the victim’s Outlook address book and sent infected emails to all contacts, exponentially spreading the worm. The infected email contained the malicious attachment, perpetuating the cycle as more users fell victim to the deception.
