IFN643 virus Removal Guide

What is IFN643 ransomware virus?

The menace of IFN643 ransomware

Among the new ransomware of this week, IFN643 virus is another brand new malware. Its operation peculiarities do not differ much from other viruses of the same kind. It encrypts the files and marks the data with specific extensions. The threat is quite greedy as it demands more than 1000 USD in exchange for the files. Instead of paying the money, you should remove IFN643 as soon as possible. The virus is still under development, so its full capacity is unknown. However, you should not behave according to cyber criminals expectations and transfer the money. Paying the indicated amount of money might prove to be just a waste of time and financial resources. There are no guarantees that the hackers will transfer the files. IFN643 removal can be performed effectively with the help of FortectIntego.

There is much potential in this cyber threat. After acquiring the sample of this malware, it seems that the hackers have high ambitions of improving the threat into a major one. IFN643_Malware_Readme file or the message, which appears after the encryption is completed, provides very little information about what kind of ransomware it is. It mainly states:

Your most critical files are encrypted 🙂
Send $1000 in Bitcoin to udKNOr3FVaibcNY9ygVhygNfdKIojmVA93A if you need them back.

Usually, the file-encrypting malware requests 1 BTC which equals 600 dollars. However, in this case, the crooks decided to aim higher. Indeed, the threat is not a usual computer pest as it inflicts great damage: all your important files get encrypted with the help of elaborate encryption method. It has been revealed that the threat appends .IFN643 extension to the corrupted data. What is more, Word and other formats belonging to MS Office package are under the primary target.

The distribution tendencies of the file-encrypting malware

Mainly the virus prefers spreading via infected spam messages. If you think that you can easily evade them, think twice. The crooks have made up convincing techniques to penetrate into the operating system. Users should be extremely careful upon reviewing the attached file which pretends to be an invoice or the notification of delivered goods. Speaking of IFN643 malware, it sneaks into the device disguising under spoolpdf.anti.exe and spoolpdf.exe files. Trojans and exploit kits are also likely to facilitate IFN643 hijack. If you want to escape a similar threat in the future, keep in mind these recommendations. Do not rush to open any spam email even if it contains the logo of an official institution. The swindlers might easily forge the credentials of a legitimate company to create a persuasive image. In short, it would be better to exercise cautiousness and reduce the number of spam messages with a reliable anti-spyware application.

How can I get rid of IFN643 effectively?

We do not recommend you to remove IFN643 virus manually. You can do it with the help of a security tool, such as FortectIntego or Malwarebytes.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
