After DHL, Intuit is also used by cybercrime to drive Dridex globally. The bait is the usual false invoice with an .xlsm attachment which, if opened, contacts a malicious link chosen randomly from a list within it. This then downloads a DLL which infects the computer with the malware. Dridex is a very dangerous banking Trojan used by cybercrime, which has long been the protagonist of campaigns all over the world, especially with a courier theme.
