"... Now, it seems, memes are being used as a stealthy way to send commands to computers that are infected by malware. Researchers at Trend Micro have identified a Twitter account that's hiding messages inside images -- a technique referred to as steganography. The account was created in 2017, yet it sat mostly idle until two months ago. That's when the Matrix Morpheus memes appeared... Trend happened to observe unexpected interaction with this particular account after finding a new strain of malware. When activated on an infected machine the Trojan began monitoring the Twitter feed for updates... The images contained hidden "print" commands which told the Trojan to take a screen capture and send it back to its criminal controllers. That's a trick malware creators will employ when they want to steal usernames, passwords, and credit card details from their victims. The Trojan has other capabilities, too. It can harvest a list of files from an infected computer, see what programs are running, find out who's logged in on the machine, and capture any data that is copied to the clipboard." https://www.forbes.com/sites/leemat...-malware-commands-twitter-memes/#54d8cfcb7abe
