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. Attackers continue to find ways to hide their intentions from technical controls using encrypted attachments and malware hosted on trusted platforms.
TYPE: Malware – AZORult Stealer
DESCRIPTION: This quotation-themed phish has all the pressure of a high stakes auction. It’s a lot of words – many of them impactful – in a short amount of space. Rather than raising their hand for an unintended bid, the recipient of this email clicked the Cofense Reporter button so our PDC could identify a malicious link in the attached PDF that led to the AZORult Stealer malware. Going once. Going twice. Gone!
TYPE: Malware – Iced-ID
DESCRIPTION: This phishing threat isn’t just cryptic, it’s encrypted! This response-themed attack delivers a password-protected .zip archive containing a macro-laden Microsoft Office document with a .hta downloader for Iced-ID. Opening this chilly attachment would have been a grave mistake.
TYPE: Malware – WSH Remote Access Trojan
DESCRIPTION: Many of us long for the days of unfettered travel and this email spoofs an aviation company with an invoice for a booked flight. It actually delivers a link to Google Drive that will download a VBS Loader to install the WSH Remote Access Trojan. Be careful what you wish for!
TYPE: Malware – Ursnif
DESCRIPTION: Skipping the friendly skies, there’s always the open road. And any decent road trip requires a sound insurance policy. This response-themed phish goes into considerable detail to convince the recipient to click the embedded links that will lead to a password-protected .zip archive containing VBS Droppers to run Ursnif. Our recipient appraised the offer and reported it to the security team.
TYPE: Malware – Reconnaissance
DESCRIPTION: Just like the attackers, we’re throwing in this last phish as a bonus. A promise of money is often enough to lure a recipient into clicking. Had they opened the attached .html file, they would have been led to a macro-laden Microsoft Office document delivering a reconnaissance tool.
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.
