If cybersecurity concerns set your hair on fire, you should be bald by now — and lacking eyebrows and any other facial hair (perhaps even be denuded to the waist). A relentless increase in cyberattacks is prompting a reassessment of responses and an increasingly popular option is going on offense.

The list of significant cyberincidents in 2021 compiled by the Center for Strategic and International Studies includes 71 items through June. In addition to the Microsoft Exchange hack that penetrated 250,000 networks worldwide, there were the ransomware attacks on Colonial Pipeline, which shut down the U.S.' largest fuel pipeline; the attack on the world’s largest meat processing facility, JBS; on Acer, the Taiwan computer manufacturer; as well as a North Korean attack on South Korea’s Atomic Energy Research Institute; and intrusions at water processing facilities in Norway, Israel, Florida and California. The list doesn’t include the July 4 hack by REvil, a suspected Russian government supported group of cybercriminals, that hit as many as 1,500 companies in what has been called the largest ransomware attack ever.

Security protocols aren’t working and there is a new readiness to consider offensive operations. Gen. Keith Alexander, a former head of the U.S. National Security Agency, explained the new mindset: “If we are under attack, you can’t just try to catch every arrow. You have to take care of the person shooting the arrows at you.”
