Cybersecurity

Hi, I’m not a coder etc but I’m not a complete noob with computers.

My FIL has apparently been scammed / hacked by some shithead (according to wife) who has apparently managed to get control whenever he turns his laptop on. I don’t know much more than that right now. The situation is pretty shityy because the poor old man lost EVERYTHING in recent flooding; all possessions, personal documents etc. He was given this laptop to help him get his life back together, personal admin etc.

He’s actually an OG coder and mathematician but is old enough to be vulnerable to the crap that these scum pull on the unsuspecting.

I’m wondering if there’s a way (rubberduck?) to quickly delete teamware etc as soon as the pc boots. Not sure how much admin control he has anymore.

Is there a safe mode (?) way of getting back control / kicking external admins?

Many thanks for any advice.

Today I checked DNSDumpster for my domain and realized that TXT verification records for my email are visible to everyone. Should I be worried? If yes how can I hide them?

Security researchers have discovered new Bluetooth security flaws that allow hackers to impersonate devices and perform man-in-the-middle attacks.

The vulnerabilities impact all devices with Bluetooth 4.2 through Bluetooth 5.4, including laptops, PCs, smartphones, tablets, and others.

Users can do nothing at the moment to fix the vulnerabilities, and the solution requires device manufacturers to make changes to the security mechanisms used by the technology.
