For a while now the transition away from Manifest V2 (MV2) to MV3 has been on-going and it looks like it is entering its final phase of deprecation, at least, in the case of Google Chrome. A recent discussion thread in the w3c WebExtensions Community Group GitHub repo has highlighted how the latest and upcoming versions of the most popular browser are expected to be its final releases with support for MV2 extensions.
What this essentially means is that the tricks and bypasses that were used to keep MV2 extensions like uBlock Origin and others alive will not work any more on Chrome, or at least not for very long. For example the Windows Registry mod that could extend MV2 availability will cease to function after Chromium version 151.
Over 10 years ago someone at my office had their work PC and user drive encrypted with ransomware because of a bad ad injection from one of those job search sites. Thankfully it was limited to nothing critical and incremental backups restore the drive…but hopefully they found a good lead because they were canned.
If they’d had a good ad blocker this would have been a non issue
I work in IT: Pretty much all the malware we deal with comes from ads. I’ve pitched making ad blocking standard but they never go for it, even though it’s clear it would prevent an absolute shit ton of attacks. It’s crazy!
