How cryptojacking works

Hackers have two primary ways to get a victim’s computer to secretly mine cryptocurrencies. One is to trick victims into loading cryptomining code onto their computers. This is done through phishing-like tactics: Victims receive a legitimate-looking email that encourages them to click on a link. The link runs code that places the cryptomining script on the computer. The script then runs in the background as the victim works.
The other method is to inject a script on a website or an ad that is delivered to multiple websites. Once victims visit the website or the infected ad pops up in their browsers, the script automatically executes. No code is stored on the victims’ computers. Whichever method is used, the code runs complex mathematical problems on the victims’ computers and sends the results to a server that the hacker controls.

Europol describes Emotet as “one of the most professional and long-lasting cybercrime services.” Its operators used the botnet to gain entry into organizations worldwide and then sold that access to other cybercrime gangs, who used it for their own nefarious purposes, such as delivering ransomware and banking Trojans, according to Europol and security researchers. What makes this takedown interesting is how Europol managed to push out an updated botnet to infected hosts, redirecting them away from the malicious infrastructure,” says Marc Laliberte, senior security analyst at the security firm WatchGuard Technologies. “Instead of only taking down the servers responsible for distributing the malware, international l
