HACKERS FOR HIRE: Companies putting cyber specialists on payroll in effort to fend off costly attacks

Money is an important motivator, but these arrangements also work because they give an outlet to hackers who get most of their thrills from finding weaknesses instead of exploiting them.

“When all the pieces finally come together, that is the best feeling in the world,” he said. “Knowing that you have just cracked the biggest corporations.” Imagine a venue where concert tickets are on sale for $250 and $500. A hacker might try to order two of the former and negative one of the latter, hoping to be charged zero. This is the sort of scam a human can easily suss out. A computer can sell many more tickets, but is not blessed with that intuition; it’s “just a clever calculator,” De Ceukelaire said. Prohibited actions have to be explicitly ruled out, and hackers are on the lookout for oversights.

That’s what was feared last December, when a flaw in the popular Apache Log4j utility was identified. Quebec categorized the vulnerability, which could let attackers access servers without permission, as a 10 on its 10-point scale..The province responded to the discovery by shutting down nearly 4,000 websites, including Quebec.ca and its vaccine registration portal. Workers rushed to inspect them and patch the vulnerability wherever it appeared.
