Zyxel keeps malware detection up-to-date. Currently, Zyxel detects and removes the threats including Trojan.BitCoinMiner.
Trojan.BitCoinMiner identifies a program that the attackers wrote viruses to hijack other people computer's physical resources including memory and processing power. Crypto-mining typically is used with extremely powerful hardware costing a lot of money. To avoid this, Trojan.Bitcoinminer will silently installs through fake software downloads and updates, forcing regular users' computers to mine bitcoins or other digital cryptocurrency for them. Programs identified as Trojan.BitCoinMiners can either function as a miner, or install a separate component that can do so.
