Malware Analysis System Evasion:

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

Source: /tmp/UnHAnaAW.arm5 (PID: 5200)

Queries kernel information via 'uname':

Jump to behavior

May try to detect the virtual machine to hinder analysis (VM artifact strings found in memory)
