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. Phishing threat actors continue to rely on tried-and-true methods to get their attacks into user inboxes. We discussed the latest trends recently on our Phish Fryday podcast.TYPE: Malware – LolKek

DESCRIPTION: This phish uses an order theme spoofing to deliver a Microsoft Excel Binary attachment (.xlsb). Within this file, macros are designed to download and install a recently discovered form of ransomware called LolKek. Excel Binary documents aren’t as common in general usage, but come in handy when working with large files. Or malicious attachments.TYPE: Malware – Remcos

DESCRIPTION: This contract-themed phish delivers an image link designed to look like an attached Microsoft Office document. Instead, it downloads a document crafted to exploit CVE-2017-11882, download a VBS script, which downloads a PowerShell script. That script then unpacks and loads a DotNET Loader that runs the Remcos Remote Access Trojan. That’s a long way of saying system compromise.
TYPE: Credential Theft

DESCRIPTION: Taking advantage of the current pandemic, this phish spoofs the World Health Organization to convince the recipient to click the link. Doing so prompts for credentials including “Gmail, Office, Yahoo, AOL, Outlook, and ‘other’” and then directs to a Google Drive-hosted PDF. Despite the official looking sender and logo, the body is rife with grammatical errors.
TYPE: Credential Theft

DESCRIPTION: Claiming to provide an attached statement, this phish uses a linked URL masquerading as a PDF attachment to direct the recipient to a Microsoft SharePoint-hosted page designed to steal credentials. Cofense continues to cover the use of trusted cloud services for untrustworthy purposes.
TYPE: Malware – Dridex

DESCRIPTION: This invoice-themed phishing attack promises a booking invoice but delivers a macro-enabled Microsoft Word document inside a ZIP archive. Those macros lead to the installation of the Dridex malware.
TYPE: Credential Theft

DESCRIPTION: Still getting used to remote work? Attackers hope so, attempting to trick recipients into following their trusted Microsoft SharePoint links to a nasty end. In this case, a credential harvesting page. Cofense has put together a number of tips to help you defend your remote workers.TYPE: Credential Theft

DESCRIPTION: Just the fax, ma’am. This fax-themed phish encourages the recipient to open the attached .htm file. The file is designed to look like a Microsoft login page. The attacker is hoping to capture the login credentials of the recipient.
TYPE: Credential Theft

DESCRIPTION: The Coronavirus theme is still getting some mileage among attackers. This one includes an embedded URL that will try and steal credentials for “Outlook, Office365, Gmail, Yahoo, and ‘other’” services. After providing credentials, the recipient is sent to a legitimate-looking PDF in an attempt to reduce suspicion.
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.
