Detection
Score: | 60 |
Range: | 0 - 100 |
Signatures
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Sample is packed with UPX
Creates hidden files and/or directories
Detected TCP or UDP traffic on non-standard ports
ELF contains segments with high entropy indicating compressed/encrypted content
Executes the "rm" command used to delete files or directories
Sample contains only a LOAD segment without any section mappings
Sample listens on a socket
Uses the "uname" system call to query kernel version information (possible evasion)
