CrossRAT Trojan – How Does It Infect
The CrossRAT Trojan may enter your computer via many different methods, the main suspect of which is via a malicious web redirect to a page which automatically downloads and runs the .jar files which causes the infection. One sample of the malicious file, infecting with the CrossRAT Trojan has been reported to have the following technical parameters according to VirusTotal:

The bad news here is that no system is secure, even Linux OS. This suggests that very experienced malware writers may be behind this remote access Trojan.
The main method by which you may have come into contact with the CrossRAT trojan is if you have visited a web page, which causes an automatic browser redirect to a web page which can infect you simply by you having to visit it.
Another way by which you may become a victim of this Trojan horse is if you have opened a file, which you believe is legitimate and it contains the CrossRAT infection script which causes the infection by you opening the file. Such files are often fake setups of programs, fake key generators, game cracks and other software you may have downloaded via Torrent websites.
The last but not least important method by which this Trojan may have infected your computer is if you have opened an e-mail attachment, like an infected Microsoft Office document, believing it is a legitimate invoice, receipt for purchase online or other form of seemingly legitimate file. Such e-mails often pretend to come from companies from the likes of eBay, PayPal, DHL and other reputable names.
CrossRAT Trojan – Analysis
Remote access Trojans are not a new concept. However, when we see a RAT which is compatible with the three most widely used operating systems in the world – Windows, MacOS and Linux, it is definitely a cause for alarm. Furthermore, the EFF have established that the Trojan has been created and supported by the Dark Caracal hacker group, which may be based on Lebanon in order to spy on government employees and journalists in more than 20 countries all over the globe.
The CrossRAT Trojan has many capabilities, the primary of which are:
- To evade conventional anti-virus software protection.
- To manipulate the files on the computers it infects.
- To run DDL files which may contain other viruses, like miner malware or ransomware.
According to a technical report by ex-NSA hacker Partrick Wardle, the activity of the malware once it infects your computer is very sophisticated and experienced developers are behind it. Once this Trojan finds itself in a computer system, it perform the following steps:
1-Scans the infected computer in order to establish the OS it’s running, the security software installed on it.
2-Uses the information from scanning the infected PC in order to infect it with the tools which are most likely to be undetectable.
3-Assumes administrative access to gain full control of the infected machine.
The CrossRAT Trojan can be identified on different computers based on different modifications it performs on different OS’s. Here are it’s main symptoms that give it away:
