Kaspersky Lab researchers reported that it detected NukeBot \u2013 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. \u00a0\u00a0<\/strong><\/p>\n

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.<\/p>\n

As an early warning to its customers and other users, Kaspersky Lab has published a brief analysis of the malware.<\/p>\n

NukeBot is a banking Trojan. Upon infection it \u201cinjects\u201d malicious code into the webpage of an online banking service displayed in a victim\u2019s browser and then steals user data, spoofs their credentials, and more.<\/p>\n

According to Kaspersky Lab researchers, there are already a number of compiled samples of this Trojan in the wild \u2013 shared on underground hacking forums. Most of these are rough, barely operational malware drafts; however, the company\u2019s experts have managed to identify some that pose a real threat.<\/p>\n

Around 5% of all samples found by Kaspersky Lab were NukeBot\u2019s new \u2018combat versions\u2019, which have improved source codes and attacking capacities. Among other things these versions contain injections \u2013 specific pieces of code, which mimic parts of user interface of real online banking services.<\/p>\n

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.<\/p>\n

In addition, Kaspersky Lab researchers managed to detect several NukeBot modifications that didn\u2019t have web injection functionality, and were designed to steal mail client and browser passwords.<\/p>\n

This means that developers of new versions may aim to widen the functionality of this malware family.<\/p>\n

\u201cWhile criminals behind recent versions of this malware currently are not actively distributing NukeBot, this may, and likely will, change very soon. We\u2019ve already seen this before with some other malware families: after a short testing period of a ready-to-attack malware, criminals start distributing it widely through infected websites, spam and phishing. So far we have seen NukeBot versions which are ready to attack the customers of at least six banks located in France and the US, however this list of targets looks like only the beginning. The goal of our brief research is to warn the banking community and online banking customers about a potentially emerging threat. We urge interested parties to use the results of our research in order to protect themselves from this threat in advance,\u201d said Sergey Yunakovsky, security expert at Kaspersky Lab.<\/p>\n

\u201cIn 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,\u201d added Sylvia Ng, General Manager at Kaspersky Lab Southeast Asia.<\/p>\n
