Criminals are using ransomware-like tactics and poisoned websites to get your employees’ computers to mine cryptocurrencies. Here’s what you can do to stop it.
Either way, the crypto mining code then works in the background as unsuspecting victims use their computers normally. The only sign they might notice is slower performance or lags in execution.
Why cryptojacking is on the rise
No one knows for certain how much cryptocurrency is mined through cryptojacking, but there’s no question that the practice is rampant. Browser-based cryptojacking is growing fast. Last November, Adguard reported a 31 percent growth rate for in-browser cryptojacking. Its research found 33,000 websites running crypto mining scripts. Adguard estimated that those site had a billion combined monthly visitors.
“Crypto mining is in its infancy. There’s a lot of room for growth and evolution,” says Marc Laliberte, threat analyst at network security solutions provider WatchGuard Technologies. He notes that Coinhive is easy to deploy and generated $300 thousand in its first month. “It’s grown quite a bit since then. It’s really easy money.”
