What is BlackMoon virus?

BlackMoon banking Trojan steals people's banking information and delivers SkyStarts ransomware as a second payload

BlackMoon trojanBlackMoon is a banking trojan that spreads via phishing websites and steals credit card info

BlackMoon is a reference to a trojan virus, which has been first spotted on the landscape in 2014. Many cybersecurity vendors recognize it as W32/Banbra on the bases of its detection name. This specific malware example has been developed with an intention to steal the victim’s banking information by redirecting the victim to phishing websites.

This malicious cyber infection used to be extremely active until 2016 and then got idle until 2018 when experts spotted new strains of the trojan in an active development phase. The renewed BlackMoon trojan sample has been submitted on VirusTotal in autumn 2018. A year later the SonicWall Capture Labs Threat Research Team released a report that the infamous banking trojan evolved into a double payload malware.

Once installed, the renewed Trojan executes malicious activities allowing criminals to steal user's credentials and, upon a second phase, downloads SkyStars ransomware. The latter is known for encrypting personal files and appending .SKYSTARTS extension. In contrast to other ransomware-type viruses, it does not generate a ransom note, nor provides instructions on how to pay a ransom or encrypt files. ThIt mainly targets computer users in the East Asia region, mostly in Japan, China, and South Korea.

Once it gets into the victim’s computer system, it drops various infectious files. The Trojan introduces itself as a DLL file, which can be launched via the rundll32.exe executable file. This banking Trojan is designed to reroute the user to fraudulent websites whenever he/she attempts to access a search engine or an online banking portal via one of the affected web browsers. BlackMoon virus can modify all the major web browsers on Windows, including Mozilla Firefox, Google Chrome, and Microsoft Edge.

Before rerouting the user to a phishing website, the Trojan showcases a message (which can be presented in Korean, Japanese, or Chinese language), which states that the user has to complete “the security certification process,” which can be finished by signing into a bank account. Of course, this is nothing more than a scam, because then the user gets rerouted to a phishing website and all information he/she enters falls into cybercriminals' hands.

This trojan can also collect information including the victim’s personal and work phone number, social security numbers, credit card details, keystrokes, passwords, and similar sensitive data. It reaches crooks’ Command and Control servers and can be used for illegal purposes immediately.

If you presume that your computer has been compromised by this malware, do not wait and remove BlackMoon Banking Trojan from your PC immediately. You can check if your computer is infected with some kind of malware and remove it with anti-malware software.

We suggest using SpyHunter 5Combo Cleaner or Malwarebytes malware removal tool to detect and delete spyware/malware threats from the computer. Sadly, the manual removal of this Trojan would be a time-consuming process, which eventually would end up in failure. The manual decontamination of Trojan files is practically impossible. Finally, experts highly recommend fixing trojan damage upon its removal. AV tool is not likely to restore registry entries, corrupted or deleted files, and processes. Thus, try using FortectIntego system recovery tool.

Trojans infect PCs via hacked websites or malicious spam attachments

Reportedly, BlackMoon Trojan spreads via drive-by downloads, which means it can get into the victim’s computer system by taking advantage of vulnerabilities in outdated software. Additionally, this variant of malware can be downloaded in conjunction with fake software updates, typically Java Player or Flash Player updates.

While these programs are entirely legitimate, cybercriminals tend to exploit users’ trust in these programs by bundling infectious files with them and promoting such modified updates via insecure Internet sites. Therefore, we highly advise you to stay away from unknown websites and avoid downloading well-known software from them because such downloads can contain malicious files and severely damage your computer system.

Needless to say, you should always keep all your programs up-to-date and also protect your computer with a strong anti-malware solution. It is advisable to purchase a full package of services that your AV developers have to offer.

How to prevent from getting trojans

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
