![]() ![]() We already found a particular miner that first exploits a vulnerability then installs WMI (Windows Management Instrumentation) scripts in order to download its coin-mining payload. Cryptocurrency-mining malware, for instance, are capable of infecting devices to illicitly mine for cryptocurrency. This has led to crackdowns on illicit crypto-mining through browser extension and built-in blockers.Ĭryptojacking is not limited to browsers. Many websites have been reported to be cryptojacking visitors, i.e., surreptitiously stealing resources from visitors’ computers to mine for cryptocurrencies. Think of it as an alternative revenue stream to intrusive online advertising, without user consent. One controversial reason is that some companies want to monetize their websites through their users’ CPU power by adding cryptocurrency mining scripts. So why is it that aside from PCs, IoT devices, which are relatively underpowered, are displaying mining activity? Compromised devices seen attempting to mine for cryptocurrencyĬryptocurrency mining is a computationally intensive task that requires a lot of processing power. Threats to Unsecured Home Routersįigure 2. More reports have even surfaced over the years of how hackers could break into home devices like baby monitors and smart TVs to remotely snoop on personal data or seize control of the devices themselves. The botnets harnessed vulnerable devices such as IP cameras and routers to cripple several networks and wreak significant downtime. Mirai, Persirai, and Reaper botnet attacks have already driven the point home: unsecured connected devices can be highly disruptive. The sheer number of entry points can put the devices at the attackers’ mercy, either by locking them up with ransomware or even making them part of an army of botnets for distributed denial-of-service (DDoS) attacks. The current reality of having many internet-connected devices in the home, however, has given rise to another type of intruder - one whose point of entry is the home network, where connected devices are potentially open to compromise. Home intrusions are often pictured in the form of physical break-ins. ![]()
