The Daily WTF has a good story that may sound a little too familiar to some:
How the aptly-named Super Hacker had managed to shut down the system remotely and provide a fix so quickly intrigued Kiefer. After poking around the network, he finally found the Python file that contained the Super Hacker’s fix:
# Paying someone $10 to pull a power cord for $3500
print “(C) [Name Removed] 2008.”
The moral of the story: when all else fails, use social engineering.
