"The Tor Project called to help keep Russian users connected to Tor to circumvent censorship," Vitaly Kamluk, head of Kaspersky's Global Research and Analysis Team for APAC, wrote in a blog about the clipper malware. "Malware authors heard the call and responded by creating trojanized Tor browser bundles and distributing them among Russian-speaking users."
Additionally, the malware is protected with the Enigma packer v4.0, which makes analysis more complicated. So to calculate the total losses, the threat hunters collected "hundreds" of the malware samples, unpacked them from Enigma, extracted the crypto-wallet replacement addresses and then calculated the total inputs to these wallets.
One way to avoid this coin-stealing campaign is to download installers from the official Tor Project, which are digitally signed and free of malware. "A mistake likely made by all victims of this malware was to download and run Tor Browser from a third party resource," Kamluk added.
While this technique has been around for more than a decade and originally used by banking trojans to replace bank account numbers, with the rise of cryptocurrency, this new type of malware is now actively targeting crypto owners and traders.
Kaspersky technologies have detected more than 15,000 attacks using clipboard injector malware targeting cryptocurrencies like Bitcoin, Ethereum, Litecoin, Dogecoin, and Monero. These attacks have spread to at least 52 countries worldwide, with the majority of detections in Russia due to users downloading the infected Tor Browser from third-party websites as this browser is officially blocked in the country. The top 10 affected countries also include the United States, Germany, Uzbekistan, Belarus, China, the Netherlands, the United Kingdom, and France. This means the actual number of infections may be much higher than reported.

Researchers have discovered a new multi-stage malware delivery campaign that relies on legitimate application installers distributed through popular software download sites. The malicious payload delivery, which includes a cryptocurrency mining program, is done in stages with long delays that can add up to almost a month.
According to the Check Point Research team, a Turkish-speaking software developer called Nitrokod is behind the campaign, which has been running since at least 2019. Nitrokod's website claims that the developer has been creating free software applications including video and music converters, video downloaders and music players since 2017 with a combined install base of around 500,000 users.
Some of Nitrokod's Trojanized programs can be found on app download sites such as Softpedia and Uptodown. The app Check Point analyzed is called Google Translate Desktop and is a desktop application that allows people to use Google Translate's service, which is normally only available as a web service through a browser.
In fact, the Google Translate Desktop app itself is built using the open-source Chromium Embedded Framework (CEF) project that allows app developers to implement the Chrome browser in their apps to display web content. This allowed the Nitrokod authors to create functioning apps without too much effort.
Once the user downloads and installs an app, the deployment of malicious payloads doesn't happen immediately, which is a strategy to avoid detection. First, the app installer, which is built with a free tool called Inno Setup, reaches out to the developer's website and downloads a password-protected RAR archive that contains the application files. These are deployed under the Program Files (x86)\Nitrokod\[application name] path.
Up to this point, the installation is not very unusual for how a legitimate application would behave: collecting some system data for statistics purposes and deploying what looks like an automatic update component. However, after around four system restarts on four different days, update.exe downloads and deploys another component called chainlink1.07.exe. This mechanism of delaying the deployment and requiring multiple restarts is likely an attempt to defeat sandbox analysis systems, which do not test application behavior across multiple restarts.
The chainlink1.07.exe stager creates four different scheduled tasks that will execute with different delays. One of them, which executes every three days, uses PowerShell to delete system logs. Another one is set to execute every 15 days and downloads another RAR archive from a different domain that uses the intentionally deceptive name intelserviceupdate. A third scheduled task executes every two days and is set to unpack the RAR archive if it exists, while the fourth task executes every day and is set to execute another component from the archive.
Even though they are set to run with higher frequency, the third and fourth tasks don't do anything until the 15-day delayed task that downloads the RAR archive runs, since otherwise there's no archive to extract and no executable to execute.
Finally, the dropper deploys another component called nniawsoykfo1.8.exe, which then deploys two other executable files called nniawsoykfo.exe and powermanager.exe. The latter is a copy of the open-source XMRig cryptocurrency mining program, while the former is a component that controls the miner and connects to a domain with nvidiacenter in its name where the attackers' common and control server is hosted.
While fake or Trojanized apps are not a new attack vector, stealthy campaigns like this that manage to fly under the radar for years highlight why it's critically important for organizations to have strong application use policies and to enforce them for employees. Application whitelisting solutions can also be used on sensitive systems to restrict what applications and from where can be downloaded and installed by employees.
This technique of replacing clipboard contents is more than a decade old. It all started from banking trojans focused on specific banks and replacing bank account numbers in the clipboard. Here is a report from CERT Polska that warned Polish users about such a threat targeting users of local banks in 2013. However, such attacks required detecting a particular internet banking environment, and their success depended also on other fields being filled correctly (i.e. bank SWIFT code, branch name, etc). Focusing on something global and provider-independent, such as a cryptocurrency wallet, made it much more efficient for cryptothieves. Adding increased value of cryptocurrencies made it a very lucrative target. So, this is where we started seeing the first clipboard attacks on cryptocurrency owners. They were replicated and reused in other malware too. We even made a generic detection for some of such families, naming them Generic.ClipBanker.
The target user downloads Tor Browser from a third-party resource and starts it as torbrowser.exe. The installer is missing a digital signature and is just a RAR SFX (self-extracting executable) archive. It contains three files: 041b061a72
