This is a fascinating whodunit mystery that started with one of the clues left by the Ashley Madison hackers. Did you know that when Ashley Madison was hacked, every employee's computer was triggered to play the song "Thunderstruck" by AC/DC?
Brian Krebs, one of the premier computer security researchers and reporters in the country, broke the news on July 20 that Ashley Madison had been hacked. He'd been sent a link to the source code for Ashley Madison by the Impact Team, the mysterious hackers, via his website's contact form. Just hours later, a Twitter user named Thadeus Zu tweeted a link to the same source code.
Here's where AC/DC comes in. When Toronto police had a press conference recently about the hack, they revealed the "Thunderstruck" detail. Krebs then combed through five years of Zu's tweets, and found that in bragging about two hacks, one in the Netherlands and one of the Australian Parliament's website, he'd mentioned AC/DC and "Thunderstruck."
That could be mere coincidence, since both of those tweets were from 2012. But Krebs kept digging.
