Infection with a ransomware virus most often occurs through a spam letter with

an attachment. As a rule, these attachments have completely innocent names, such as "Summary".
Less often, the virus spreads infectiously, from one device to another.
If an antivirus with fresh databases is installed on the computer, the virus can be
recognized and deleted, and the files can be decrypted by selecting passwords taiwan whatsapp number list for the encryption methods used in a particular virus.
However, some encryption viruses work
much more “reliably”: some, like Trojan.Encoder.102, require
weeks or even months of decryption, while others (Trojan.Encoder.283)
are completely impossible to decrypt correctly.

"Ransomware is distributed via phishing emails, malicious websites, or in complex attacks. Once downloaded and executed on an infected system, the program (as the name suggests) encrypts files of most common formats, including .txt, .doc, .xls, .jpg, .mov, .avi, and others. The encryptor then displays a ransom demand on the screen.
<p>Once infected, the user loses access to their files. Paying the ransom does not guarantee receiving the decryption key. Most modern encryptors (CryptoLocker and its modifications) use the asymmetric RSA encryption algorithm, which allows storing the decryption key on a remote server, rather than in the code of the malware itself."

Many people pay the ransom in the hope of regaining access to their files, which partly explains the popularity of encryptors among cybercriminals: it is simply profitable. However, a significant proportion of encryptors do not provide for sending the user a decryption key, even if they have transferred the required amount. “I repeat: paying the ransom does not guarantee that access to the files will be restored,” emphasizes Artem Baranov.
