[Arinerron]

... #471: malloc(0x18)                                                                              = 0x7ffff792da40 
... #472: malloc(0x18) 
    |-- warning: return value is not a heap pointer
    |   * this indicates some form of heap corruption
    |   * pointer is inside of section "<malware>" (0x555555554000-0x5555555f8000)                                           

when I run it on the malware it:

• doesn't bold the "warning" heading
• returns a chunk inside of the elf?? todo investigate
