A malvertising campaign is using the Invalid Printer loader to drop the Aurora information stealer.
Malicious ads trigger a fake Microsoft Windows update which presents the victim with a bogus Chrome update.
Before dropping the payload Invalid Printer first performs a range of checks to confirm the malware is not running in a VM or sandbox.
