TrickBot is a banking trojan that was first detected in September 2016 and since that time had been developed to incorporate the targeting of multiple geographies and online services. The malware was developed to gain unauthorized access to customer bank accounts to facilitate fraudulent transactions, but also targeted users of online services such as Salesforce and cryptocurrency services. The malware was reportedly delivered via spam emails containing malicious attachments, including those distributed by the Necurs botnet, and via the RIG exploit kit. In some cases, TrickBot used an exploit called EternalBlue (affects CVE-2017-0144) or Windows API calls to propagate in a local network. The functions and activities of TrickBot are reportedly very similar to the Dyre banking trojan, and it was assessed by researchers to be linked to this trojan, including that at least one of the developers of Dyre was involved in the development of TrickBot.
