Security Research & Analysis Threat Analysis

Shopping for Christmas gifts has never been easier, especially with Amazon—and who doesn’t use Amazon? This is why using fake Amazon orders is a favorite method bad actors have been using this time of year to bait rushed Christmas shoppers. As a warning to anybody (everybody?) caught up in receiving last-minute Amazon deliveries, we've come across a malicious email campaign (see image below) to install a variant of the Emotet malware, a polymorphic banking Trojan that is virtual machine-aware and primarily functions as a downloader or dropper of other malwares.

Phishing Security Research & Analysis

Criminals are nothing if not financial opportunists, and the boom in phishing has been like a cybercrime gold rush: While some are panning for gold, others are selling the tools and equipment.

Security Research & Analysis Threat Analysis

It gets earlier and earlier every year. The first Yuletide-related malware campaign has already been spotted. There’s always an expected and monumental amount of consumer spam and phishing in the run-up to Black Friday and then Christmas itself, but we’ve found one malware author getting into the Christmas “spirit” in late October by targeting backdoor-delivering emails at the Yuletide supply chain, specifically Christmas goods suppliers whose preparations for the year-end commercial convulsion are well underway.
