Cetori ransomware virus

Cetori ransomware already penetrated many machines in different parts of the world through most effective manner: scam messages with dangerous attachments. Occasionally hackers use zero-day vulnerabilities to get into the PC, but big software companies promptly correct them. After penetration, Cetori scans the hard disc, determines the amount of files for encryption and their general worth. Currently, any modern virus can cypher audio, text, image and video information in all popular extensions. High attention is attracted to businesslike documents, because medium and large companies are the main objective for scammers. All software in the system will be untouched since criminals are interested only in information. Encryption is carried out through world-known RSA and AES algorithms, and its intricacy is so above the average level that decipherment of data without a key is impossible. Such complexity gives ground for impressive effectuality of ransomware in last years: an ordinary PC operator, even if he has a very high experience in suchlike things, won't ever get back the data, and will be forced to pay the price. The sole way to get back the data is to hack the fraud site and withdraw the encryption keys. Some experienced hackers can withdraw the keys via defects in viruses’ program code.

The computer knowledge is very important in our century, since it assists user to guard the laptop from computer viruses. It is sad to say, but most people see the significance of computer knowledge just after ransomware infection. To defend your system, you have to remember three simple rules:

  • Do not accept any alterations to your computer, coming from unknown programs. The most effective way of file restoration is the recovery via Shadow Copies, so Web-criminals have included the elimination of those copies in the basic functionality of viruses. However, deletion of shadow copies requires administrator rights and user's confirmation. Thus, not accepting alterations from a unknown software at the proper moment, you will keep the way to recover all encrypted data for free.
  • Don't neglect the symptoms that your hardware and software shows. It requires a lot of computing power to encode the information. When the virus starts to work, the CPU performance decreases, and the encryption process is visible in Process Manager. You might catch this event and shut down the computer before files will be totally lost. These measures, if the system is really infected, will save a lot of your files.
  • Be careful with the messages that contain something more than a message. The most popular pattern of fraud messages is the notification about prize winning or package obtaining. The other common kind of such letters is a "business messages". It is natural to be interested and open the message even if it's sent to the improper address, but don't forget that one click on the viral file can cost you lots of efforts, time and money.
