Yesterday’s computer viruses are tame in comparison to today’s and the financial damages, while significant, pale in comparison. For a look back at some of the earliest malware a visit to Internet Archive’s Malware Museum is recommended. For a look at today’s computer viruses recently discovered, take a look at McAfee’s Threat Activity List.

Most internet vulnerabilities are secret and/or unknown. Some vulnerabilities are public knowledge, such as Microsoft’s termination of support for Internet Explorer 8, 9 & 10 on Tuesday, February 9, 2016. Think of the millions who will now be vulnerable to viruses because they or their organizations are too “busy” to update their browsers. Most of the victims are likely to be government organizations who are notoriously slow at upgrading software.
