Antivirus / Scanner detection for submitted sample

Multi AV Scanner detection for submitted file

ELF contains segments with high entropy indicating compressed/encrypted content

Sample has stripped symbol table

Uses the "uname" system call to query kernel version information (possible evasion)

Classification

Analysis Advice

Static ELF header machine description suggests that the sample might not execute correctly on this machine.

Non-zero exit code suggests an error during the execution. Lookup the error code for hints.

Static ELF header machine description suggests that the sample might only run correctly on MIPS or ARM architectures.

Description:	Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.

Description:	Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment. This may include things such as firewall rules and anti-virus. Adversaries may use the information from Security Software Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
