Phish Found in Proofpoint-Protected Environments – Week Ending August 2, 2020
100% of the phish seen by the Cofense Phishing Defense Center (PDC) have been found in environments protected by Secure Email Gateways (SEGs), were reported by humans, and automatically analyzed and dispositioned by Cofense Triage.
Cofense solutions enable organizations to identify, analyze, and quarantine email threats in minutes.
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. We note quite a bit of spoofing this week. Attackers know if they can get their phishing attacks into a user’s inbox, they still need to convince the user to click.

TYPE: Malware – Pyrogenic
DESCRIPTION: For such a polite email is carries an awfully impolite payload, as this finance-themed phish uses an embedded URL disguised as a PDF to deliver the Pyrogenic Stealer.
TYPE: Credential Theft
DESCRIPTION: Spoofing an international logistics company, this phish delivers an attached PDF with embedded links to a credential phishing site.
TYPE: Malware – NanoCore
DESCRIPTION: Everyone knows Dropbox is a legitimate cloud storage provider so, when we get a purchase order hosted on Dropbox, we click it. At least, that’s what the attacker hopes. In this attack, an archive holding the NanoCore Remote Access Trojan is downloaded. We’ve been discussing the use of Dropbox in phishing attacks for over 5 years.
TYPE: Malware – Avaddon
DESCRIPTION: Another spoof of a major logistics company. This one really delivers. Using an embedded URL it delivers the Smoke Loader that then downloads Raccoon Stealer and Avaddon Ransomware. Read more about ransomware trends.
TYPE: Credential Theft
DESCRIPTION: Stop me if you’ve heard this one. A spoofed voicemail notification uses an attached .htm file to mimic a Microsoft page to steal credentials. Voicemail notification phish are nothing new, but still reach users regularly.
TYPE: Malware – Remcos
DESCRIPTION: Self-quarantines and remote work arrangements seem like a recipe for increased deliveries and this phish takes advantage of that. Another logistics company spoof offers an invoice as a lure. In a rare twist, the attack delivers a .xxe archive that contains GuLoader, which will install the Remcos Remote Access Trojan.
TYPE: Malware – Ursnif
DESCRIPTION: Another attack relying on trust in a popular cloud storage provider. This one includes a link to a .js file that downloads and executes Ursnif. Are we having trust issues?
TYPE: Malware – IcedID
DESCRIPTION: If it is protected by a password, it must be secure. That’s the lure this attacker uses to convince the recipient to open the attached .zip archive, enable the macros in the provided Microsoft Office document, and install the IcedID trojan. It’s a blast from the past, as we wrote about password-protected ZIP files in phishing attacks way back on 2011.
TYPE: Credential Theft
DESCRIPTION: While we hoped to get through an entire week’s blog without a COVID-19 example, it wasn’t meant to be. This phish pretends to be from the US Small Business Administration with details about an approved funding request. The embedded URL leads to a credential phishing page. Recipients should keep their mouse at least 6 feet away from the link.
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.
Cofense recommends that organizations train their personnel to identify and empower them to report these suspicious emails. Cofense PhishMe® customers should use SEG Miss templates to raise awareness of these attacks. Organizations should also invest in Cofense Triage and Cofense Vision to quickly analyze and quarantine the phishing attacks that evade Secure Email Gateways.
