According to some estimates, "O ver 98% of malware making it to the sandbox array uses at least one evasive tactic." And new, more sophisticated techniques and types of malware capable of this are coming out every day. But the point should be clear: Malware that can evade sandboxes is pervasive. There are other techniques hackers can use to outsmart sandboxes, including hiding malicious code in password-protected attachments, data obfuscation and encryption. In response, malware developers have come up with techniques in which their creations make it appear that they are doing something like executing useless CPU cycles to delay the actual code from acting until the sandbox has released it into the work environment. Unless they can detect a good reason for an application to sleep, they may ban it on suspicion of being malware. To defend against this, sandboxes have been updated. It might take sandboxes as long as 20 minutes to check a file, so malware that sleeps for at least that long will be passed through the system.
