Detection

Score: 56
Range: 0 - 100
Whitelisted: false

Signatures

Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
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
Uses the "uname" system call to query kernel version information (possible evasion)
