Find Out If Your E-Mail Is Part of This Spambot Network
When one of the top cyber security guys is vulnerable, you know you definitely are, too. An easy way to find out if your address is vulnerable is to visit Have I Been Pwned? You can input your address and find out if your info was collected in a hack, and specifically when. It cross references the list with known hacks and shows you the potential vulnerabilities. I plugged one of my e-mail addresses into the list, and found out it may have been compromised after the Adobe hack of 2013.
I recommend NOT using any of these passwords, which were dubbed the worst passwords of 2016, and are probably still pretty bad.
