The 'Help50@yandex.ru' Ransomware is a ransomware Trojan that is designed to encrypt the victim's data and then demand the payment of a ransom. Ransomware Trojans that use an attack similar to the 'Help50@yandex.ru' Ransomware have become common in the last few years increasingly and represent a significant threat to the computer users' data. Fortunately, computer users can make themselves invulnerable to these attacks by simply having backup copies of their data.

Stay Away from the 'Help50@yandex.ru' Ransomware
The 'Help50@yandex.ru' Ransomware uses a strong encryption algorithm to make the victim's files inaccessible completely. Once the victim has been locked out of the affected files, the 'Help50@yandex.ru' Ransomware demands the payment of a ransom. The 'Help50@yandex.ru' Ransomware is distributed using corrupted spam email attachments that will use macros to install the 'Help50@yandex.ru' Ransomware. This ransomware Trojan also may be distributed through the use of corrupted links included in spam email messages. After encrypting its victim's files, the 'Help50@yandex.ru' Ransomware renames them by adding, at the end of the affected file name, the extension '.dat.' The 'Help50@yandex.ru' Ransomware receives its name because this is the email address that is used by the 'Help50@yandex.ru' Ransomware to communicate with victims of the attack.
How the 'Help50@yandex.ru' Ransomware Carries out Its Attack
The 'Help50@yandex.ru' Ransomware uses the XOR encryption to make the victim's files inaccessible completely. XOR is not considered as secure as the AES 256 and RSA 1024 encryption algorithms more commonly used in these kinds of attacks. However, XOR encryption allows the 'Help50@yandex.ru' Ransomware to carry out its encryption very quickly, which is a priority for the people responsible for the 'Help50@yandex.ru' Ransomware attack. The use of the XOR encryption makes the possibility of a decryption utility to be released by PC security researchers, although it may be not possible to recover files affected in the 'Help50@yandex.ru' Ransomware attack currently. In its attack, the 'Help50@yandex.ru' Ransomware will target numerous file types, including files associated with commonly used programs, media files, image files, and numerous others files, adding the extension '.dat' to mark all the files affected in the attack. The 'Help50@yandex.ru' Ransomware delivers its ransom note in a text file that is dropped on the victim's desktop. This file contains a very short message, which reads:
'For restore your files write: help50@yandex.ru.'
Computer users should avoid contacting the people responsible for the 'Help50@yandex.ru' Ransomware attack. Doing so exposes you to simply additional hoaxes and does not guarantee the return of your data. Instead, computer users should take precautionary measures against the 'Help50@yandex.ru' Ransomware and similar encryption ransomware Trojan threats.
Dealing with and Preventing the 'Help50@yandex.ru' Ransomware Attacks
Con artists will follow up on their promises to help computer users recover from the attack rarely and even after a ransom is paid, which can be of several thousand dollars, they may ignore the victim or ask for even more money. Apart from this uncertainty, paying the 'Help50@yandex.ru' Ransomware ransom allows these people, which are probably based in Russia, to continue creating and distributing threats, claiming new victims in further attacks. Instead, computer users should take precautionary measures. The best single precaution computer users can take to ensure that the 'Help50@yandex.ru' Ransomware attack becomes ineffective is to have backups of all files or disk images. Having a backup version of your data allows you to recover from the 'Help50@yandex.ru' Ransomware attack easily, making it impossible for con artists to threaten you in any meaningful way. Apart from file backups, malware analysts advise computer users to also use a security program to intercept and remove the 'Help50@yandex.ru' Ransomware infection and similar attacks. A combination of security software and precautionary measures to limit the damage of the 'Help50@yandex.ru' Ransomware attack can protect most computer users from the 'Help50@yandex.ru' Ransomware and the many variants of this hoax that are active today.
