Google says it has deployed patches for zero-day vulnerabilities that a Spanish tech company may have used to develop spyware.

2021 accounted for more than 40% of the zero-day exploits undertaken in the last decade, according to the company.

There were 58 total. The good news: Detection and disclosure of zero-day exploits have increased, the research team says.

Five zero-days found in Aethon TUG robots included one that could allow an attacker to control the machines, Cynerio said.

Data from the Google-based team seems to reflect an industry getting faster at fixing bugs and deploying patches.

Apple released a patch on Sept. 23.

That's a dozen so far this year alone, as zero-days are having a record year everywhere.

Apple released its iOS 14.8 update Monday.

Other details about the vulnerability were thin.

Hackers are going after Internet Explorer, even on its deathbed.
