Fraudulent UPS Delivery Emails Contain Links to Malware

Fraudulent UPS delivery notification emails have been circulating that appear legitimate but contain links containing malware. The link opens a Microsoft® Word® document containing a malicious macro, which opens a scripting shell that downloads and opens a malicious executable file.

In the following screenshot of a UPS notification email, all links are legitimate except for the tracking number link.

Clicking the link opens a Microsoft Word document like the one in the following screenshot. The document contains a malicious macro.

ACA Aponix recommends verifying that each URL directs to a trusted source before clicking any link in an email, regardless of whether the email appears to be legitimate. To do this in Microsoft® Outlook®, hover your mouse over the link.

Update to Juniper Networks Critical Security Update for ScreenOS

On December 17, 2015, Juniper Networks released an out-of-cycle security bulletin for vulnerabilities in ScreenOS. Since then, an additional vulnerability was discovered in ScreenOS that makes it possible for attackers to gain full administrative access to affected devices.

This vulnerability affects all NetScreen devices running ScreenOS 6.2.0r15-6.2.0r18 and 6.3.0r12-6.3.0r20. Juniper ScreenOS devices are commonly used for firewalls and home VPNs.

More information

ACA Aponix recommends applying the latest patched releases of ScreenOS and limiting device access to trusted networks only. However, it is important to note that no fix has yet been released to prevent the decryption of VPN traffic. We will be conducting vendor diligence around the patching of these issues.
