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, Reimage or Malwarebytes Anti Malware 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 Since ts emergence, these programs might have failed in detecting the threat due to outdated virus definitions.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.
