Not only has cryptojacking hit the big time, but now attackers are moving to target Linux.
Crypto-mining malware is becoming a key tactic for cyber-criminals, with 98.8 percent of common Linux/Downloader malware variants analysed in the first quarter of 2018 being designed to deliver a Linux-based cryptocurrency miner.
The Linux/Downloader is a generic signature for a range of malicious Linux shell scripts, but in Q1 2018 it has been almost entirely attempting to download and run a Linux-based crypto miner (MD5: 748c0b329ab9cc06e7bbe06822fbe767748).
Another key indicator of the rise of cryptojacking, according to the latest Internet security report from WatchGuard Technologies, is that another cryptominer shows up as the 24th threat on the top 25 malware list.
“Besides these two hidden signs of crypto miners in our Q1 data, we have more up-to-date intelligence suggesting that crypto miners continue to grow in Q2. During early Q2, our daily data shows various “Coin Miners” continually appearing on our top 25 list. While it’s too early to say if they will break the top 10 for Q2, we expect them to continue to grow in popularity over the next few quarters”, commented the WatchGuard researchers.
