Other Details

This Trojan connects to the following website to send and receive information:

• stratum+tcp://{BLOCKED}l.{BLOCKED}r.com:80

It does the following:

• It uses a hardcoded credentials for the mining server.
• This hacking tool is a CPU miner used to generate cryptocurrency.
• The mining process eats up a system's computing power. As such, infected systems sustain increased wear and tear from processing coin blocks and the infected systems will work abnormally slow.
• accepts the following parameters:
  • -a, --algo=ALGO cryptonight (default) or cryptonightite
  • -o, --url=URL URL of mining server
  • -O, --userpass=U:P username:password pair for mining server
  • -u, --user=USERNAME username for mining server
  • -p, --pass=PASSWORD password for mining server
  • -t, --threads=N number of miner threads
  • -v, --av=N algorithm variation, 0 auto select
  • -k, --keepalive send keepalived for prevent timeout (need pool support)
  • -r, --retries=N number of times to retry before switch to backup server (default: 5)
  • -R, --retry-pause=N time to pause between retries (default: 5)
  • --cpu-affinity set process affinity to CPU core(s), mask 0x3 for cores 0 and 1
  • --cpu-priority set process priority (0 idle, 2 normal to 5 highest)
  • --no-huge-pages disable huge pages support
  • --no-color disable colored output
  • --donate-level=N donate level, default 5%% (5 minutes in 100 minutes)
  • --user-agent set custom user-agent string for pool
  • -B, --background run the miner in the background
  • -c, --config=FILE load a JSON-format configuration file
  • -l, --log-file=FILE log all output to a file
  • -S, --syslog use system log for output messages
  • --max-cpu-usage=N maximum CPU usage for automatic threads mode (default 75)
  • --safe safe adjust threads and av settings for current CPU
  • --nicehash enable nicehash/xmrig-proxy support
  • --print-time=N print hashrate report every N seconds
  • --api-port=N port for the miner API
  • --api-access-token=T access token for API
  • --api-worker-id=ID custom worker-id for API
  • -h, --help display this help and exit
  • -V, --version output version information and exit,0

It does not exploit any vulnerability.
