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

Update: post-reinstallation and monitoring incoming connections, I'm happy to say the sounds have not returned. This has given me the motivation to install a Netgate 1100 with pfSense ahead of the PC. Thank you all!

Ik it's a long shot and wasn't really what you were asking for. I've just had family with schizophrenia and it's important to like... Idk leave the door open to it sometimes

    I have a friend that struggles with delusional disorder, so I'm no stranger to such disorders. But I assure you, having had to listen to these 7-10s soundbytes, find out the sources (Karma Factory/South Park/Morse Code) for weeks now... of sound mind (didja see what I did there lol), it's real and it sucks.

    Still hoping someone can point me to a log file I can grep against for sounds.

    Okay ah see to me it was almost a tell that you already knew the sources, didn't know you had to figure out where they were from.

    Okay I'm trying to think:

    • Attach a debugger to your kernel, break right when you hear the noise, and then do a full memory dump. Then share it with us here. If you have to be crafty, write a script to send a break right when sound emits. You might need a second computer for this.
