What is OPdailyallowance ransomware? And how does it carry out its attack?
OPdailyallowance ransomware is a new file-encrypting threat discovered by MalwareHunterTeam recently. This crypto-malware was created based on the open source platform known as HiddenTear. It uses a .CRYPTR extension in marking encrypted files. According to security experts, it appears that this new threat is a customized version of FSociety which was also a HiddenTear-based ransomware. Just like a typical ransomware threat, it starts its infiltration by dropping a malicious payload in the system. After that, it makes modifications which allow it to run on every system boot automatically. It also employs a data gathering module used to collect data about the computer and the user. The collected data, along with some malicious components are then used for stealth protection which allows the malware to carry out its attack without any interference from the installed programs in the computer.
After making changes in the infected computer, it will look for files to encrypt in the system. Once it finds its targeted files, it encrypts them using the AES cipher and appends the .CRYPTR extension to the encrypted files. After successful encryption, it opens a file named “INSTRUCTION.html” which contains a lengthy ransom note. Here are some parts of the ransom note:
Can’t find the files that you need?
Is the content of your files that you need, unreadable?
This is normal because the data in your files have been encrypted.
