Hackers Hijacked Macs Through a Screen Sharing Bug to Secretly Mine Monero — Here's What You Need to Know

WHY IT MATTERS

Imagine someone sneaking into your house and using your electricity to run their own business — that's essentially what cryptojacking is. Hackers found a flaw in a feature built into Mac computers (Screen Sharing) and used it to secretly install software that mines Monero, a privacy-focused cryptocurrency. Mining crypto requires a lot of computing power, so your computer would slow down and your electricity bill would go up, all while the hackers pocket the mined coins. Monero is often used in these schemes because, unlike Bitcoin, its transactions are hidden — think of it like digital cash with no receipt — making it very hard for authorities to follow the money. This matters because it shows that even everyday computer users can be unknowingly pulled into the crypto world through cybercrime.
