Signatures

Connects to many ports of the same IP (likely port scanning)
Opens /sys/class/net/* files useful for querying network interface information
Performs DNS TXT record lookups
Sample deletes itself
Sample scans a subnet
Detected TCP or UDP traffic on non-standard ports
Executes the "rm" command used to delete files or directories
Sample has stripped symbol table
Uses the "uname" system call to query kernel version information (possible evasion)
