Onset Delay

Created the Monday 11 March 2019. Updated 4 years, 2 months ago.

Malware will delay execution to avoid analysis by the sample. For example, a Ping can be perform during a time defined. Unlike extended sleep that will use the Sleep function, onset delay will use another way to delay execution.

The purpose of such evasive code is to delay the execution of malicious activity long enough so that automated analysis systems give up on a sample, incorrectly assuming that the program is non-functional, or does not execute any action of interest.
