Are phishing emails evading your Proofpoint Secure Email Gateway? The following are examples of phishing emails seen by the PDC in environments protected by Proofpoint. With a preponderance of XXE attachments being used to reach inboxes, organizations would be best served by restricting these attachments manually as well as inventorying their archive management tools, such as WinRAR, to assess their risk.TYPE: Malware – Agent Tesla

DESCRIPTION: This German-language, quote-themed phish uses a linked image that looks like a quote but leads to the Agent Tesla Keylogger. Cofense has written about the commercialization of Agent Tesla, bringing malware to the masses.TYPE: Credential Theft

DESCRIPTION: Delivery-themed phish are a global phenomenon, as this French-language email delivers embedded links to lure a recipient into clicking and giving up their credentials. Just report as phish and delete, s’il vous plait.
TYPE: Malware – Remcos

DESCRIPTION: This finance-themed attack continues the recent surge in the use of .xxe archives to get malware into inboxes. This phish delivers the Smoke Loader that will then install both the Remcos and NetWire Remote Access Trojans. Talk about a double-whammy!
TYPE: Malware – Remcos

DESCRIPTION: Another .xxe example with a similar look and feel as the previous, but using a shipping theme. In this case the Remcos Remote Access Trojan is delivered by the GuLoader malware held within the delivered archive.
TYPE: Malware – Smoke Loader

DESCRIPTION: Another finance-themed phish. This one spoofing a bank to deliver… you guessed it… another .xxe archive. This one installs the Smoke Loader malware, which Cofense used to see delivered via Microsoft Office exploits. It seems you can teach an old dog new tricks.
TYPE: Malware – Remcos

DESCRIPTION: While it normally only takes 3 examples to indicate a pattern, we have a 4th XXE archive delivery this week. Another finance-themed phish that delivers a GuLoader to download and activate the Remcos Remote Access Trojan.Malicious emails continue to reach user inboxes, increasing the risk of account compromise, data breach, and ransomware attack. The same patterns and techniques are used week after week.
