NukeBot: New Ready-to-Attack Version of Dangerous Banking Trojan Caught in the Wild

NukeBot: New Ready-to-Attack Version of Dangerous Banking Trojan Caught in the Wild
25 July 2017

Kaspersky Lab researchers have detected NukeBot – new malware which has been designed to steal the credentials of online banking customers. Earlier versions of the Trojan were known to the security industry as TinyNuke, but lacked the features necessary to launch attacks. The latest versions however, are fully operable, and contain code to target the users of specific banks.  

Although the appearance of a malware family in the wild is not unusual, the fact that criminals have a ready-to-attack version of the Trojan, means that soon they may initiate a wide-scale malicious campaign, to infect multiple users. As an early warning to its customers and other users, Kaspersky Lab has published a brief analysis of the malware.

NukeBot is a banking Trojan. Upon infection it “injects” malicious code into the webpage of an online banking service displayed in a victim’s browser and then steals user data, spoofs their credentials, and more. According to Kaspersky Lab researchers, there are already a number of compiled samples of this Trojan in the wild – shared on underground hacking forums. Most of these are rough, barely operational malware drafts; however, the company’s experts have managed to identify some that pose a real threat.

Around 5% of all samples found by Kaspersky Lab were NukeBot’s new ‘combat versions’, which have improved source codes and attacking capacities. Among other things these versions contain injections – specific pieces of code, which mimic parts of user interface of real online banking services. Based on the analysis of injections, Kaspersky Lab experts believe the main targets of the new version of NukeBot are users of several French and US banks.

In addition, Kaspersky Lab researchers managed to detect several NukeBot modifications that didn’t have web injection functionality, and were designed to steal mail client and browser passwords. This means that developers of new versions may aim to widen the functionality of this malware family.

“In 2016 the number of users attacked with malware targeting financial data increased about 30.55% over the previous year, bringing it to close to 1.1 Million attacks. While most of these attacks were mostly towards regular users, approximately 17.7% of the attacks also targeted corporate users. From our Financial Cyberthreats report for 2016, we found that users in Russia, Germany, Japan, India, Vietnam and the US are the ones most often attacked by banking malware. The trends show us that although professional cybercriminal groups have indeed shifted a lot of their attention to targeted attacks against large companies, regular users and smaller firms are still being targeted” said Sylvia Ng, General Manager, South East Asia at Kaspersky Lab.

To protect yourself and your customers from NukeBot attacks, Kaspersky Lab security specialists offer the following advice:

For financial organizations providing online banking services:
·         Make sure you have an effective fraud prevention solution in place, so that you can quickly and accurately spot unauthorized use of customer accounts and irregular financial activity.

For customers of online banking services:

·  Use an Internet security solution with tailored technologies to protect financial transactions, like Kaspersky Lab’s Safe Money
·  Regularly run a system scan to check for possible infections.

Kaspersky Lab products detect the malware as Trojan-Banker.Win32.TinyNuke.
