Infection Flow of Crypt888 Ransomware

Crypt888 ransomware has evolved, but the changes are focused primarily at user interfaces rather than making better its code. The distributors of this offensive threat have changed the ransom instructions several times providing them in different languages including English, Italian, Czech and now in Portuguese. Apparently, the analysis of the latest Crypt888 variant shows that the AutoIT script, the encryption algorithm, encryption key, the created files names, and various other components still be the same as in the previous versions.

In one of the earlier versions of the ransomware called Mircop attackers have provided Anonymous designed wallpaper. Then they have demanded a ransom of 48.48 Bitcoins, or close to $28,730.70.

Falling installation on victim’s computer Crypt888 may drop these three files in the %Temp% folder:

  • c.exe
  • x.exe
  • y.exe

Unlike the common ransomware mechanism, Crypt888 doesn’t append extension after the names of the encrypted files but prepends the string ‘Lock.’ instead. When this happens, it means that the files are encrypted with strong encipher algorithm and are unable to be opened by any program. Furthermore, the crypto virus may also be designed to lock some common folders like Downloads, Desktop, Documents, etc.

Besides file encryption Crypt888 may steal credentials from victim’s web browsers, messaging services and other accounts.

Crypt888 drops a file that is the picture of its ransom note and replaces it with the current desktop wallpaper. The new ransom note of Crypt888 starts with the word “AVISO” which is in Portuguese and means “Warning” in English. The depicted text on the ransom note reads:

Ola Sr(a),
TODOS os seus arquivos foram BLOQUEADOS e esse bloqueio somente serão DESBLOQUEADOS
caso pague um valor em R$ 2000,00 (dols Mil reais) em Bitcoins
Apos o pagamento desse valor, basta me envair um print para o email…
[email protected]
que estarei lhe enviando o programa com a senha para descriptografar/desbloquear o seus arquivos,
Caso o pagamento nao seja efetuado, todos os seus dados serao bloqueados
permanentemente e o seu computador sera totalmente formatado
(Perdendo assim, todas as informacoes contidas nele, incluindo senhas de email, bancarias…)
O pagamento devera ser efetuado nesse endereco de Bitcoin:
Para converter seu saldo em bitcoins acesse o site:”

The malicious intenders behind Crypt888 virus harass victims to pay $ 2,000.00 in Bitcoins in order to send back a decryption key for the ‘Lock.’ files. Otherwise, they intimidate that they will block all data permanently and the computer will be completely formatted.

We notice that there is no provided name of the threat in the ransom note which is yet another attempt to trick users hit by Crypt888 that they have been infected with decryptable ransomware. In fact, the security specialists from AVG have developed a free decryption tool that allows all victims to decode the ‘Lock.’ files. So don’t be panic just keep reading the information we provided and save yourselves completely from Crypt888 ransomware that has encoded all your files making them looking like this one:
