It does seems like it, but I'm completely puzzled by the level of sophistication the attacker must have gone to hack my account. I mean super strong unique password + 2FA + firewall + AV? What individual can hack that? It just doesn't make any sense...
What AV are you running? You mention it in the post as well. A huge number of these services/tools have major vulnerabilities. (The few I used to recommend/trust really haven't ever worked properly with Windows 11.)
