Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Machine Learning detection for sample
Sample deletes itself
Sample reads /proc/mounts (often used for finding a writable filesystem)
Sample tries to kill multiple processes (SIGKILL)
Deletes log files
Detected TCP or UDP traffic on non-standard ports
Enumerates processes within the "proc" file system
Executes commands using a shell command-line interpreter
Executes the "grep" command used to find patterns in files or piped streams
Executes the "kill" or "pkill" command typically used to terminate processes
Found strings indicative of a multi-platform dropper
Reads CPU information from /sys indicative of miner or evasive malware
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
Sample has stripped symbol table
Sample tries to kill a process (SIGKILL)
Uses the "uname" system call to query kernel version information (possible evasion)
