A phishing campaign is underway which is distributing a new variant of the DanaBot Trojan. The DanaBot Trojan was first identified in May 2018 and has been actively distributed via phishing emails for more than two years. In the summer of 2020, activity slowed but the campaigns resumed in October.
DanaBot is a modular banking Trojan used in targeted geographical attacks on businesses. The first variant that emerged in 2018 was used in targeted attacks in Australia, while the second variant was primarily used in attacks on U.S. companies. Attacks have also been conducted in Europe, primarily in Ukraine, Austria, Poland, Italy, and Germany.
The latest variant is the fourth to be identified and has been released around a year after the third variant was identified in February 2019. The latest variant has had several technical anti-analysis changes made to the main component of the malware and its method of maintaining persistence has changed. The latest variant now achieves persistence through a LNK file loaded into the user’s startup folder, which launches the malware when the device is booted.
Affiliates are used to conduct campaigns distributing the DanaBot Trojan under the malware-as-a-service model. Several new affiliate IDs have been added which suggests the malware-as-a-service operation is growing. It is therefore probable that DanaBot will grow into a much bigger threat in 2021.
Previously, DanaBot has been primarily distributed via spam emails that deliver a malware dropper, which downloads the banking Trojan via a multi-stage process. It now appears that the malware is being distributed via websites that offer cracks and software keys for pirated software such as graphics software, VPNs, antivirus software, and games.
Protecting Against Banking Trojans by Blocking Malware Delivery
Protecting against DanaBot and other Trojans requires a range of security measures. Two of the most important are an advanced spam filter and a web filtering solution. The spam filter will detect malicious emails that attempt to deliver the malware dropper, while the web filter will block access to the websites that are used to download the malware.
TitanHQ has developed a spam filtering solution – SpamTitan – that provides protection against known and unknown malware variants and a web filter – WebTitan – that prevents users from accessing malicious websites and categories of website commonly used to distribute malware.
With both of these cost-effective cloud-based cybersecurity solutions implemented, businesses can block the two most common vectors used to distribute malware and keep their networks and devices well protected.
