Regarding its operational capabilities, the malware uses either forkpty or pipes and a forked new process to set up a reverse shell for the attacker to remotely access the infected device.

#Sedexp also employs memory #manipulation techniques to hide any file containing the string "sedexp" from standard commands like 'ls' or 'find,' concealing its presence on the system.

Samples from Red Stone were also analyzed by instruments that simulate those used on Mars, but even finding organics in these samples was challenging. A GC-MS instrument comparable to but ten times more sensitive than #Curiosity rover’s SAM instrument was barely able to detect specific biogenic organic compounds at the limit of detection, suggesting that SAM could not have detected them.
