There is always a trace. You need better cybersecurity, to prevent them from penetrating the network to start with, and to root them out after the fact. Consult with firms like Cloudstrike, FireEye and other specialists who cope with nation-state malicious actors likw China and Iran and who can deal with this, as well, albeit for a price.

I don't have a solution, but you have my sympathies. That's really horrible.

So..... My company (HQ based in Geneva) has been subject to a targeted attack against an employee. It started with constant spam about how he is an abuser, rapist, etc. His email has been compromised twice.

The attacks (this is almost a year later) have now turned to other employees who work with him (including me). Think nude photos, sexual and racist comments about employees.

Has anyone had anything like this happen before and was there a solution?

They are apparently investigating but the hackers are sophisticated enough to not leave a trace.
