In fact, as a criminal, I may find an individual and I don’t necessarily have to target them—I might target a family member that lives in the same house, who may not be as security savvy. Once I’m on that family member’s computer, I’m now on the same network as the person that I want to go after. I was in the security community and the hacker community—there’s a little bit of overlap between the crypto community and the security community—so I primarily stayed in that world. After doing some security startup stuff—then Trustwave got sold to Singapore Telecom (Singtel), I worked at Rapid7, helped them go public, another cybersecurity company—I decided I’m gonna take a break. I went and joined an AI company, and was running security for them for a couple of years. A mutual friend of mine and Dave Ripley, who’s our CEO at Kraken, connected us.

Use the experience to better understand how the attacker was able to compromise your systems. Update your user, helpdesk, IT, and SOC analyst training so they are better able to identify cryptojacking attempts and respond accordingly. Network monitoring tools can offer a powerful https://www.tokenexus.com/ tool in picking up on the kinds of web traffic and outbound C2 traffic that indicates cryptojacking activity, no matter the device it is coming from. Criminals are using ransomware-like tactics and poisoned websites to get your employees’ computers to mine cryptocurrencies.

How does Cryptocurrency Mining Work?

People earn cryptocurrency by using their computers to either solve or verify the solutions to math problems. Even if a cryptojacker does not plan to spend the cryptocurrency they “earn” by using your device’s resources, they can simply put them in a liquidity pool and earn that way.

The bot used a tool named haiduc to find systems that it could attack by taking advantage of a command injection vulnerability.

Malware infects the devices of people that visit the site, making them unwilling participants in cryptocurrency mining processes. Protecting yourself online is key to avoiding becoming a target of cryptojacking attacks. Now that you know how What is cryptojacking to detect and prevent cryptojacking, consider learning how to protect yourself against other cybercrimes like identity theft. According to a report by ReasonLabs, in the last year 58.4% of all Trojans detected were cryptojacking coin miners.
