When this malware has emerged, it has sparked suspicions that it has been created on the basis of Delphi scripting language[2]. It is said to be popular among unexperienced wannabe hackers for its simple structure. However, such assumptions have been denied. The ransom message states that the files are encoded with the assistance of AEs-256 algorithm. Interestingly, PEC 2017 malware operates by exploiting CVE-2017-0199 system vulnerability[3]. In other words, when users open a .doc file attached to a corrupted email, he or she spots a prompt box stating that “This document contains links that may refer to other files. Do you want to update this document with the data from the linked files?” When a user enables this content, the executable sends an HTTP request to deliver corrupted HTA file. Likewise, the malicious RTF file contains another embedded script. This triggers mshta.exe file which triggers malicious file. Since the hackers promote their specific tool for data recovery, it is likely that the virus might be decrypted soon. However, until then opt for alternative solutions. In short, remove PEC 2017 and proceed further to data recovery options.

Note that cyber criminals forge persuasive emails which are presented as fake tax reports or notifications about an undelivered parcel or email[4]. In addition, it is necessary to improve the overall security level of the device. For that, combine anti-virus and anti-malware security applications, such as FortectIntego or Malwarebytes, to secure the device. They might also help in eradicating file-encrypting malware as well. Note a trojan also facilitates PEC 2017 hijack. According to the statistics, it is now detectable as Ransom_CRYPEC.A, Trojan.Win32.Filecoder, Ransom.FileCryptor!8.1A7[5].

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
