From Exploited flaws, HARD’s guide to the flaws being used in attacks
This article lists the flaws CISA added in May 2022. For the newest, see Exploited flaws.
In May 2022, CISA added 83 flaws to its list of vulnerabilities being used in attacks, 65 of them in things people have at home; 18 have been used by ransomware gangs. Most came from Microsoft (37), Apple (8) and Adobe (7).[1]
Most let an attacker take over the product, running their own code or taking full control. It was the second most CISA added in any month of 2022.
List of flaws
Every flaw CISA added in May 2022, newest first, in plain English, each with an article of its own.[2] marks the ones used in ransomware.
