A record year for zero-day bugs, how often do you test backups, and the world’s biggest penetration test returns

A record number of zero-day vulnerabilities were found and disclosed last year. That’s according to a report this week from Google. A zero-day vulnerability is a bug exploited by attackers before a developer can create a patch. Google says 58 zero-days were found in 2021, compared to 25 the year before. That’s the bad news. The good news is that Google doesn’t think this is because software developers are getting worse at creating secure code. It’s just that the ability of security researchers to spot zero-days being exploited has increased. Also, more software companies are disclosing zero days in their applications. But not all. So that means it’s highly likely there were more zero-day vulnerabilities than 58 found last year.
