Hacked PC - random sounds playing (sh.itjust.works)

My fellow penguins,

I have been pwned. What started off as weeks of smiling everytime I heard a 7-10s soundbyte of Karma Factory's "Where Is My Mind" has now devolved into hearing dashes and dots (Morse Code) and my all-time favorite, a South Park S13: Dead Celebrities soundbyte of Ike's Dad saying, "Ike, we are sick of you talking about ghosts!"

It's getting old now.

I feel like these sounds should be grepable in some log somewhere, but I'm a neophyte to this. I've done a clean (secure wipe >> reinstall) already, the sounds returned not even a day later.

Distro is Debian Bookworm. So how do I find these soundbytes? And how do I overcome this persistence? UFW is blocking inbound connection attempts everyday, but the attacker already established a foothold.

Thank you in advance. LOLseas

There's the https://en.wikipedia.org/wiki/Sinkclose vulnerability which afaiu could compromise the CPU itself. Haven't heard about it being actually exploited, but who knows.
