Telegram desktop app exploited for malware, cryptocurrency mining

Telegram has fixed a security flaw in its desktop app that hackers spent several months exploiting to install remote-control malware and cryptocurrency miners on vulnerable Windows PCs.The programming cockup was spotted by researchers at Kaspersky in October. It is believed miscreants have been leveraging the bug since at least March. The vulnerability stems from how its online chat app handles Unicode characters for languages that are read right-to-left, such as Hebrew and Arabic.
