PhoneNumber virus Removal Guide
What is PhoneNumber ransomware?
PhoneNumber ransomware is a crypto-malware that uses a phone number of the victim as an extension for encrypted files
PhoneNumber ransomware is malicious software that encrypts all data on the device and the network of an organization and demands ransom for the decryption tool
PhoneNumber ransomware is a somewhat unique file locking virus that was first spotted attacking organizations and companies in mid-September 2019. While the goal of malware remains the same as many others – extorting money from victims by locking their files – the way, it modifies files is quite a bit different than usual.
Instead of appending an extension that points to ransomware name or version, PhoneNumber virus attaches a random prefix, which is unique to each file. The structure of the file is also modified by appending a phone number of the organization, for example, .619-388-6500. The example, a file encrypted with PhoneNumber ransomware would look like this: 8nAY3Hy – Imgur.jpg.619-388-6500.
PhoneNumber ransomware then drops a ransom note which explains that all the data was locked using RSA-4096 and AES-256 encryption algorithm – it is named after the abbreviation of the infected company followed by _README_!.txt. Crooks ask for an unknown amount of payment in cryptocurrency, and request company officials to email them via [company_name]@protonmail.com
|Encryption algorithm||RSA-4096 and AES-256|
|File extension||A contact phone number of the affected organization is used|
|Decryption||Can only be decrypted using backups or third-party software|
|Removal||To terminate ransomware infection, you should scan your computer with anti-malware software like ReimageIntego|
Because PhoneNumber ransomware uses an extension that is unique to each organization, it is highly likely that targeted attacks are used to infect the desired network. For that, crooks often use privilege escalation techniques after infecting the host with a backdoor or other malware or by infiltrating a poorly protected Remote Desktop connections. Targeted phishing emails might also be used for the purpose. Nevertheless, it does not mean that PhoneNumber ransomware cannot infect regular computer users.
Soon after the infection, PhoneNumber ransomware encrypts all files on the device and the network, deletes all backups (if it can access them), and encrypts all files, preventing everybody from accessing them. The key that can unlock data is stored on a remote server which is only accessible to threat actors. This tricky situation leaves company owners in a tricky situation: paying the ransom to retrieve important files or using alternative methods that might not always work.
PhoneNumber ransomware is malware that uses the phone number of the company as a file appendix for encrypted data
Security researchers advise avoiding paying the ransom and rather focus on PhoneNumber ransomware removal, as well as alternative data recovery methods. Because the malware is a new strain, it is yet unknown what type of criminal group is behind it, so there is no guarantee that the decryption tool will be provided after the payment.
To convince victims that the decryption is possible, PhoneNumber virus authors offer an alleged free decryption service:
Check this message in details and contact someone from IT department.
All your files are encrypted with the strongest millitary algorithms (4096 bit RSA and 256 bit AES).
Do not modify or rename encrypted files – this may cause decryption failure.
If you want to restore your files you will need to make the payment.
You can send us an encrypted file (about 300KB) and we will decrypt it for free, so you have no doubts in possibility to restore the files any time.
Files should not contain sensitive information (databases, backups, large documents, etc).
The rest of the data will be available to you after the full payment.
Contact us only if you are authorized to make a deal from the whole affected network.
Don't contact us if you are not a such person.
Use english when contacting us.
If you don't get an answer within one day download BitMessage software.
While paying the ransom is not recommended, some organizations might not have another choice (multiple high-profile companies and states in the USA opted to pay). The side effect of the action, however, only fuels the illegal business of cybercriminals behind ransomware. However, before you attempt file recovery from backups, third-party software, or by paying the ransom, you should remove PhoneNumber ransomware from your computer, or the retrieved data will be encrypted repeatedly.
For that, you need to use a powerful security solution – we recommend using ReimageIntego or SpyHunter 5Combo Cleaner, although any other comprehensive anti-malware software should do the job. In some cases, PhoneNumber ransomware termination might require accessing Safe Mode with Networking – we provide the instructions on how to reach in the removal section below.
Use security measures on your company computers in order to prevent infiltration of ransomware
The notorious case of high-profile organizations being attacked by ransomware comes from WannaCry outrage back in 2017. It seems that after the ordeal that infected over 200,000 computers worldwide left consequences that were behind just recovery costs and days of disruptions – many new malware strains started targeting companies with higher ransom demands. A few good examples of ransomware that was extremely successful in attacking companies and counties include:
Therefore, organizations should make sure that they are using the latest security technologies that provide all-around protection from most ransomware attacks. Educating staff about cybersecurity is also very important, as phishing attacks are one of the main vectors when it comes to malware infections in the organizations.
PhoneNumber ransomware not only appends the extension to the files but also uses a random (unique) hash that is added to the front of the file
Additionally, Remote Desktop connections should always be secured with a strong password, and the default port should never be used – this allows hackers to scan the internet for vulnerable connections and install the malicious payload manually.
PhoneNumber ransomware removal instructions
PhoneNumber virus deletes all the Shadow Volume Copies – a typical action performed by ransomware in order to complicate the recovery process. In some cases, however, it can fail to do so. Therefore, there is a chance of restoring the encrypted data without paying criminals – you should first remove PhoneNumber ransomware, however.
For PhoneNumber ransomware removal, you should use anti-malware software, such as ReimageIntego or SpyHunter 5Combo Cleaner. Be aware that malware can interfere with security tools, so you should access Safe Mode with Networking – we explain how to do that below.
Once you terminate PhoneNumber ransomware infection, you can connect your backups and copy the files over. If the virus removed them, there are low chances of restoring data for free. Nevertheless, you should try using third-party recovery tools that might be able to retrieve at least some of your data.

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
