XiaoBa virus Removal Guide

What is XiaoBa ransomware virus?

XiaoBa is a file-encrypting virus that threatens users since 2017

The image displaying XiaoBa trojan namesXiaoBa is a ransomware-type cyber threat that demands to pay the ransom in exchange for data recovery tool.

XiaoBa is a file-encrypting virus that started its activity at the end of October 2017. Originally, it aims at Chinese computer users[1] and encodes their files using RSA-2048 and AES-128 cryptography. Encrypted files become unusable due to the appended file extensions – .XiaoBa1 or .XiaoBa34. However, in June 2018, a new variant of the virus has been detected. It seems that developers decided to launch international cyber attacks and aims at English-speaking computer users. The latest version of ransomware locks data with .AdolfHitler file extension.

Associated emails B32588601@163.com, BaYuCheng@yeah.net
Distribution Spam emails, fake updates, etc.
Decryption Unavailable
Elimination Download and install FortectIntego or Malwarebytes

It seems that XiaoBa virus arrives on the system with the help of malicious spam emails. When users open an obfuscated attachment, malware payload is downloaded and executed on the computer. Following data encryption, ransomware explains how victims can recover their files in two ransom notes – _@XiaoBa@_.bmp and_@Explanation@_.hta (the note greatly resembles the one used by WannaCry ransomware).

The second variant of XiaoBa ransomware came out later that year in November. Because the virus used FlyStudio[2] adware trojan, this version was also dubbed as FlyStudio ransomware. Victims are asked to pay 250 RMB ($37.7) in BTC and contact cybercrooks via B32588601@163.com email. Once inside the system and finished with its file encryption activity, virus displays such ransom note:

Ooops, your important files have been encrypted!
!—— 重要加密 —— !
你柏所有文件已被 RSA-2048 AES-128 算法進行了加密
請硕縦破解 , 因為您無 眷破解文件可能導致文壊 這可能會損害他們
如果您看到這個壁紙卻看不到 “XiaoBa” 窗口 , 那麼就是您的防病毒軟件
運行解密軟件 , 並按照說明進行操作
想獲取更多信息請點擊桌面的 _@Explanation@_.hta

Though the virus is not as elaborate as WannaCry virus, it is capable of deleting shadow volume copies.[3] What is more, the virus also disables startup repair functions, which only makes XiaoBa removal more complicated.

Next, at the end of February 2018, cybersecurity experts detected the third variant of XiaoBa ransomware, which appends the .Encrypted[BaYuCheng@yeah.net].XiaBa file extension to encrypted files. It also generates a ransom note named _XiaoBa_Info_.hta, which introduces the ransomware and indicates how much the victim has to pay for XiaoBa decryptor. Besides, this infection plays a voiceover from a VBA file and distinguishes from the others due to extremely high CPU consumption.

XiaoBa virusPopular security programs can identify XiaoBa virus and eliminate it without any problems.

Besides, the ransomware has also been found to install these three files:

  • _@XiaoBa@_.bmp
  • _@Explanation@_.htaa
  • xiaoba.exe

The above-given files are associated with the first XiaoBa malware version, while the executable pdf_20180118.exe has exceptionally been found in the third virus version.

While the original version is oriented to Chinese-speaking users, the third version might also seek for Japanese computer users' money as the picture it generates on the desktop features Japanese characters.

XiaoBa ransomwareXiaoBa informs about data recovery possibilities by changing affected computer's desktop picture.

The newest variant was discovered by MalwareHunterTeam[4] in early May 2018; it came back with a new extension – .[BaYuCheng@yeah.net].china. Security experts note that it is the first variation of the virus that uses a country name in the file appendix. The ransom note is very similar to the previous version; however, it is written in Chinese only. It seems to be actively spreading via fake Flash updates.

The fact that it is written in a traditional and not simplified version of Chinese, sparks doubts about the initial target.
In case victims run into technical difficulties, they can contact the perpetrators via B32588601@163.com email address. It is not recommended to remit the payment but remove XiaoBa ransomware instead. FortectIntego or Malwarebytes might be of use in this situation. Even if the malware deletes shadow volume copies in advance, you can recover the data with the assistance of online backup copies if you have set up them in advance.

The screenshot of XiaoBa ransom noteXiaoBa is a file-encrypting malware that usually infiltrates the system after opening malicious spam email attachment. In this way, it can bypass detection and start data encryption.

XiaoBa started using .AdolfHitler file extension to victims' personal files

In June 2018, malware researchers reported that new variant of ransomware emerged. Malware is executed from New Folder.exe file which typically is dropped from the malicious email attachment. Immediately it starts scanning the system and looks for the file to encrypt.

This time creators of malware launched a campaign targeted at English-speaking computer users, and use the name of a German historic figure. During data encryption, it appends .AdolfHitler file extension. After that, it provides data recovery instructions in # # DECRYPT MY FILE # #.bmp which becomes affected computer's wallpaper. Additionally, it delivers a pop-up window informing about ransomware attack and plays audio in the background. Thus, this cyber attack is loud and cannot be overlooked.

XiaoBa AdolfHitler ransomwareXiaoBa AdolfHitler ransomware is an English variant of the file-encrypting virus.

In the pop-up window, authors of the XiaoBa AdolfHitler ransomware informs that files are encrypted using RSA-4096 encryption and can be decrypted only with a specific software. In order to take this offer, victims have to send an email to BaYuCheng@yeah.net in seven days time. The new background picture also provides the same threatening message:

I am very sorry that all your files have been encrypted!

Your file i snot destroyed, it is only encrypted, and it can be recovered after decryption.

Do not use third-party tools to decrypt files. This is very likely to result in file corruption. Please contact us for decryption!

Contact email: BaYuCheng@yeah.net for more content.

We use the powerful RSA-4906 asymetric algorithm, please fo not try to crack the file! Contact us the right way.

However, security specialists do not recommend following hackers' instructions. Crooks may not provide the decryption software once they receive the ransom. Hence, instead of risking to lose the money, remove .AdolfHitler file virus from the machine with anti-malware software.

Cyber criminals might use multiple methods to spread ransomware

The malware is likely to be spread via typical means of distribution.[5] You can get infected with ransomware threats via spam emails, trojans, corrupted apps, and extensions. Exploit kits are also known to help distribute certain ransomware, but at the moment, there is no information whether this particular threat uses the services of these hacking tools.

Therefore, it is crucial to pay attention to the received spam folder. Even if the email urges to open a highly important email attachment, verify the sender before extracting the contents. Cyber villains prefer targeting users with invoices, package delivery notices, etc.

In addition, fortify the overall protection of the device with a few different type applications. Do not download content from websites with no HTTPS protocol or crowded with ads. These tips should assist you in warding off XiaoBa hijack in the future.

How to prevent from getting ransomware

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.
