Cryptoboss ransomware impersonates Globe3 virus

The picture illustrating CryptoBoss

Cryptoboss virus functions as a file-encrypting threat. After it infiltrates the system, it appends .cryptoboss file extension. The malware makes a preference for German users. Nonetheless, residents of other regions might be assaulted with this malware as well. Taking into account its style of ransom, the threat impersonates Globe2 and Globe3 ransomware[1]. However, it is assumed that the malware is, in fact, another version of recently emerged file-encrypting Amnesia virus.

The ransom notification displays two email addresses: admin-amnesia@protonmail.com and admin-amnesia@bigmir.net. One of its peculiarities is that the malware presents a ridiculously long victims‘ ID. Furthermore, the size of ransom is directly related to victims‘ response time. Naturally, if he or she delays contacting the racketeers, the ransom proportionally increases[2].

Nonetheless, we advocate Cryptoboss removal rather than paying the money. For that purpose, ReimageIntego or Malwarebytes is useful. Note that the latter program should be updated. Since ts emergence, these programs might have failed in detecting the threat due to outdated virus definitions.

Initially, its imitation of well-known Globe family of ransomware made users think that it could be decrypted with Globe3 Decrypter. Unfortunately, this malware seems to be an improved alteration of Amnesia malware. Cryptoboss malware seems to be functioning similarly to other malware as it connects to a remote Command and Control server[3].

Moreover, the crooks urge to contact victims as soon as possible. The longer they wait, the higher is the ransom. The fraudsters also try to be user-friendly as they offer free decryption of a file which is smaller than 1 MB in size.

As common for hackers, they also alarm users not to use third-party decryption software. However, there is no guarantee that the felons would return all files. Thus, it would be wiser to remove Cryptoboss.

Ways to distribute ransomware

There is a variety of possible distribution channels how Cryptoboss ransomware has seized your computer. According to affected users‘ comments, this malware is quite persistent as it encrypts files even if a user restores the system and restores files from backups. It operates under the disguise of a trojan.

It may as well employ the services of exploit kits[4]. You should not also disregard the probability that the virus may assault users via spam emails. Usually, such emails present to be important tax refund documents or invoices. On the other hand, if you take a second look, you might notice that such emails contain grammar or typing mistakes.

You might also check the credentials if hackers disguise under the name of employees of an official institution. In addition, CryptoBoss hijack may occur when you install a corrupted Adobe Flash player update or similar program[5]. Be vigilant and improve your computer security with computer security tools.

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.
