The new Chrome version 88.0.4324.150 from Thursday differs from version 88.0.4324.146 published on Tuesday only in that it has a closed security hole. This is called CVE-2021-21148 and is rated “high” by Google.
Mattias Buelens, Belgian developer of an HTML5 video player, reported the problem last Sunday. Shortly afterwards, Google’s Threat Analysis Group (TAG) warned of attacks by hackers assigned to North Korea. According to the Google warning, the state spies disguise themselves as security researchers.
