Researchers at computer security firm McAfee Labs discovered a lethal new cryptojacking malware called "WebCobra," which steals victims' computing power to mine the cryptocurrencies Monero or Zcash secretly.

Infections Spotted In Brazil, South Africa, USA

McAfee Labs says the Russian application WebCobra stealthily installs the Cryptonight miner or Claymore's Zcash miner, depending on the configuration of victims' machine.

"On x86 systems, it injects Cryptonight miner code into a running process and launches a process monitor," McAfee observed. "On x64 systems, it checks the GPU configuration and downloads and executes Claymore's Zcash miner from a remote server."

While the malware originated in Russia, researchers claim they have spotted it around the world, with the highest number of infections found in Brazil, South Africa, and the United States.
