PIVOTPIPE sleep mask COFF extraction (sleepmask.o) for memory evasion
Detects the PIVOTPIPE loader extracting a 'sleepmask.o' Common Object File Format (COFF) file into a temporary directory prefixed with 'nb_'. This behavior is associated with the deployment of post-exploitation sleepmask functionality designed to obfuscate or encrypt beacon memory footprints to evade memory scanners.
