CryptoShuffler – How Does It Infect
At the moment there is a large ongoing attack carrying the CryptoShuffler Trojan which targets computer victims on a global scale. The malware is known for being updated several times with specific distribution tactics and strategies for each one. This time the security analysis reveals that there is a mixed approach using different delivery methods at once.
A primary approach is the coordination of spam email messages that use various social engineering tricks in order to make the targets interact with the malware element and infect themselves. This is done by spreading files that cause the infections either by hyperlinking them in the body contents or directly attaching them to the messges.
The emails are also one of the primary mechanisms for deploying infected payloads. Two of the most popular types are the following:
- Infected Documents — The CryptoShuffler Trojan code can be embedded in virus documents of all kinds: rich text documents, spreadsheets or presentations. The most common way is to use macros, they are enabled after the users click on the spawned notification prompt that is executed once the document is opened.
- Software Installers — In a similar way the criminals behind the CryptoShuffler Trojan can place the dangerous code in application installers. The hackers typically download the legitimate setup files from the official vendor sites and modify them to include the malware code. Usually popular software are chosen such as system utilities, creativity suites, productivity, office programs and even computer games.
Usually cryptojacking threats like this one are delivered to the prescribed victims using web scripts. They can infect legitimate sites as well by taking advantage of affiliate and ad networks. Other methods include redirects, pop-ups, banners, in-content links and others.
In this regard the CryptoShuffler Trojan can be delivered through browser hijackers which are malware plugins made for the most popular applications: Mozilla Firefox, Safari, Microsoft Edge, Opera, Google Chrome and Internet Explorer. They are usually distributed on the browser plugin repositories with elaborate descriptions and fake user reviews. Once installed they redirect the users to a hacker-controlled site and deliver the accompanying virus.
CryptoShuffler – More Information and Analysis
The CryptoShuffler Trojan was detected for the first time in August 2016 with several major updaets since then. It’s code has been found on the hacker underground markets and used in other viruses. One of the distinct characteristics of it is that it is often accompanied with miners. This means that certain version of it can bundle such code in a hybrid form.
The associated malware engine has been found to be modular in nature and this means that it can be customized to reflect the predetermined targets.
Like ransomware threats it may begin the infection with a data harvesting component. Unlike viruses the threat may not be interested in personal data that can directly reveal the victim’s identity. Rather it harvests details about the hardware components and running services. Using the list of installed applications the CryptoShuffler Trojan can perform a security bypass action. This is used to prevent programs and services from interrupting the virus’s proper execution. Target applications include anti-virus apps, virtual machine hosts and sandbox environments. In advanced configurations we have seen malware that remove themselves if they are unable to overcome the security measures.
Various Windows Registry changes can follow. Usually this targets user-installed applications entries that can lead to the inability to launch certain functions and services. When the operating system entries are affected overall performance may degrade severely. Changes to it can also make the CryptoShuffler Trojan infection a persistent threat. This means that it will automatically start once the computer is booted. The boot options themselves are changing by removing the possibility to enter into the recovery boot menu. This prevents most of the manual removal attempts, in such situations the only to effectively recover the compromised hosts is to use an automated anti-spyware solution. Refer to our removal instructions in this article.
A special “service daemon” is instituted onto the computer which monitors the web browser activities. The cryptojacking activities are a special kind of intrusion attacks. The associated malware engines looks out for any interaction with cryptocurrency-related sites and software wallets. Whenever a transfer is made the virus will automatically replace the recipient address so that the funds will be sent to the hackers. Additionally the hacker operators of the CryptoShuffler Trojan can hijack any found wallets and account credentials to online cryptocurrency platforms.
Usually this is done by looking for strings associated with Bitcoin or aany of the popular alternatives such as Monero, Dash, Ethereum, Zcash and Bitcoin Cash.
CryptoShuffler Trojan code can initiate a server connection to a hacker-controlled server. This is used to report the gathered information. In certain configurations it can be used to spy upon the victims in real-time and take over control of the infected hosts. We would like to remind our readers that such actions can be used to deploy additional threats to the machines.
