ILOVEYOU, also known as the love letter or the LoveBug virus, was first discovered in May 2000. The malware was delivered to millions of users as an email attachment with the subject line “ILOVEYOU.” Once opened, it spread to every contact in a user’s Microsoft Outlook address book and overwrote certain files (e.g., JPEG and MP3 files) from the hard drive.
Considering how many organizations relied on Outlook for all their email needs at the time, ILOVEYOU was fairly widespread. According to a retrospective report, the virus affected over 45 million computers within 10 days, resulting in
approximately $10 billion in damages.
