Displaying the more “classic” behavior of so-called “cryptojacker” malware, WebCobra runs almost without a trace, McAfee Labs says, the only noticeable difference for the end user being reduced hardware performance.
“Coin mining malware is difficult to detect. Once a machine is compromised, a malicious app runs silently in the background with just one sign: performance degradation,” researchers write, adding:
“As the malware increases power consumption, the machine slows down, leaving the owner with a headache and an unwelcome bill.”
As Cointelegraph previously reported, instances of such malware have shot up almost 500 percent in 2018, leading commentators to warn of an epidemic. Monero, as a cryptocurrency focused on privacy and anonymity, was reported as forming the preferred target for miners.
