What is RobbinHood ransomware? And how does it implement its attack?
Robbinhood ransomware, also known as Enc_RobinHood ransomware is a file-encrypting threat that’s making a comeback after it was first spotted way back in April 2019. Like its previous version, this new and improved ransomware threat targets a large scale of corporations and municipalities. It encrypts the entire network that is connected to the initial host.
As soon as it infiltrates a system, it begins to alter essential system settings which allow the crypto-virus to stay undetected by security programs in the system. It also makes alterations in the Windows Registry, allowing Robbinhood ransomware to run automatically each time the infected computer starts. Once all the modifications are implemented, it starts encrypting files with specific formats on the computer.
In its encryption process, Iron ransomware uses a combination of AES and RSA ciphers and appends the “RoEncrypted_[random 16].Enc_robbinhood” extension to each one of the affected files. After that, it will drop a ransom note named “_Decryption_ReadMe.html” containing the following context:
“What happened to your files?
All your files are encrypted with RSA-4096, Read more on https://en.wikipedia.org/wiki/RSA_(cryptosystem)
