What is PhoneNumber ransomware? And how does it implement its attack?
PhoneNumber ransomware is a data-encrypting malware spotted mid-September 2019 that uses its contact phone number as its extension in marking the files it encrypts. It was reported to be attacking organizations and companies and uses both the RSA 4096 and AES 256 encryption algorithms.
When it implements its attack, PhoneNumber ransomware will start by dropping its malicious payload which is used to initiate a connection to a remote server. After that, it creates and downloads malicious files and places them to system folders. It also makes entries in the Windows Registry so that it can run automatically whenever you start your computer. It then scans the computer for files to encrypt – this includes files that are commonly generated by users like documents, images, videos, audio files, and so on. Once it finds its targeted files, it will encrypt them using a combination of RSA 4096 and AES 256 ciphers. Following file encryption, it adds the contact number of the affected company or organization to every affected file and releases a text file named “!_[company_name]_README_!.txt” which has the following content:
Check this message in details and contact someone from the IT department.
All your files are encrypted with the strongest military 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 the 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 such a person.
Use English when contacting us.

How is the malicious payload of PhoneNumber ransomware distributed over the web?

Thus, you have to be more careful in what you download over the internet and make sure to scan the file before you open it.
