NOTES:

This hacking tool is a Bitcoin miner used to generate Bitcoins.

It may be bundled with a malware to send to other machines and use the affected machine to mine for Bitcoins. The affected machine uses high CPU power, which also requires more electricity. This may result in higher electricity bills.

It does not have rootkit capabilities.

It does not exploit any vulnerability.
