The Colonial Pipeline Ransomware Hackers Had a Secret Weapon: Self-Promoting Cybersecurity Firms

This story was co-published with MIT Technology Review. On Jan. 11, antivirus company Bitdefender said it was “happy to announce” a startling breakthrough. It had found a flaw in the ransomware that a gang known as DarkSide was using to freeze computer networks of dozens of businesses in the U.S. and Europe. Companies facing demands from DarkSide could download a free tool from Bitdefender and avoid paying millions of dollars in ransom to the hackers. But Bitdefender wasn’t the first to identify this flaw. Two other researchers, Fabian Wosar and Michael Gillespie, had noticed it the month before and had begun discreetly looking for victims to help. By publicizing its tool, Bitdefender alerted DarkSide to the lapse, which involved reusing the same digital keys to lock and unlock multiple victims. The next day, DarkSide declared that it had repaired the problem, and that “new companies have nothing to hope for.”
