Rewterz Threat Alert – Dridex Banking Trojan – IoCs

Severity

Medium

Analysis Summary

This Dridex campaign spoofs FedEx. FedEx Corporation, short for Federal Express, is an American multinational delivery services company headquartered in Memphis, Tennessee. The spam emails arrive with the subject “FedEx Billing Online – Invoice Ready for Payment” from the spoofed email address ‘donotreply@fedex[.]com’. Dridex is still using an anti-debugging technique to postpone execution and evade analysis. Dridex also no longer delivers payloads to Windows 7 operating systems. It appears English-speaking countries and Italy are currently the primary targets of this campaign.
