• There is a bug 4842633.
• It's not malware.
• Problem occurs due to IPv6 fragmentation.
• Fix will be available in 2021MR4 → eta: November 2021. 

As a workaround:

• Open KSC, select Settings → Protection → Network attack blocker → switch off Treat port scanning and flooding as attack.
• In Windows, disabling IPv6 may also help.
