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. Of note is the use of macro-enabled documents using Microsoft Office document extensions dating to versions sold prior to 2007. Organizations may want to consider ways to identify and filter these files.TYPE: Malware – Dridex

DESCRIPTION: Macro-enabled Excel documents and Dridex malware – name a more iconic pair. This phishing attack used Microsoft Excel documents to deliver Dridex to the inbox. Just like we’ve been blogging about since 2017.TYPE: Malware – ZLoader

DESCRIPTION: Who uses XLS files anymore? Well, attackers for one. This attack uses the long outdated file type to execute macros that download ZLoader via a VBS chain. Cofense Triage customers have been detecting and remediating attacks delivering ZLoader since 2017.
TYPE: Credential Theft

DESCRIPTION: This phish leverages a trusted cloud storage service to capture login credentials from the Danish-speaking victim. This should come as no surprise, as Cofense has been seeing the use of trusted cloud services for years.
TYPE: Malware – NetWire

DESCRIPTION: Microsoft’s Office Equation Editor vulnerability (CVE-2017-11882) has been a favorite for attackers. Discovered in 2017, malicious documents are delivered via attachment or, as in this case, embedded URL to compromise victims. This example delivers the NetWire Remote Access Trojan.
TYPE: Malware – ZLoader

DESCRIPTION: Another attack using the old XLS format with macros to deliver ZLoader. This one uses an invoice theme to trick its victims into opening the attachment.
TYPE: Malware – Agent Tesla

DESCRIPTION: This invoice-themed phish includes an embedded URL to download a .7z archive. Inside the archive is the ever-popular Agent Tesla, a top threat as recently as last year.
TYPE: Credential Theft

DESCRIPTION: While we saw plenty of malware in this week’s batch, the old standard of credential phish is still around. This profile-themed phish spoofs a state agency to capture credentials that are exfiltrated using Google forms.TYPE: Malware – Hive

DESCRIPTION: This purchase order-themed phish delivers an embedded URL to the FireBird Remote Access Trojan variant known as Hive.
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.
