Critical macOS Screen Sharing Flaw Exploited for Silent Crypto Mining

Security researchers in the Netherlands have identified a critical vulnerability in macOS Screen Sharing, reportedly rated 9 out of 10 in severity. The flaw could allow attackers to gain unauthorised access to affected systems and silently run cryptocurrency mining software in the background without the user's knowledge.

Silent crypto-mining attacks like this typically slow down computers, increase power consumption, and can indicate deeper security weaknesses that attackers might later exploit for more damaging purposes, such as data theft. Because the vulnerability affects a built-in macOS feature, businesses using Apple devices for remote screen sharing or IT support should be particularly attentive to patch updates from Apple.

While full technical details of the exploit have not been made public, the high severity rating suggests it should be treated as an urgent priority. Businesses should ensure all Mac devices are running the latest software updates as soon as Apple releases a fix.
