What is Badday ransomware? And how does it execute its attack?


Badday ransomware is a cryptovirus discovered in early October 2019. According to reports, it is a new variant of the GlobeImposter 2.0 ransomware that uses a “.badday” extension in marking the files it encrypts. Like other GlobeImposter variants, Badday ransomware is created to lock important data in a computer and demand ransom from victims.

The instant its malicious payload is dropped on a targeted machine, Badday ransomware will start to carry out its attack. It connects the computer to a remote Command and Control server where it downloads other files that will be used for its attack. These files are placed in system folders. It then begins employing an information-gathering module to obtain data in the system. The obtained information will be used for the other module called stealth protection which is used to keep the crypto-malware undetected. Badday ransomware also makes modifications in the Windows Registry to achieve persistence in its attack. After that, it scans the computer in search of files that are commonly generated by users like documents, databases, images, audio files, and a whole lot more.

Once it finds its targeted files, it encrypts them using the AES cipher and appends the .badday extension to each one of the encrypted files. Following data encryption, it opens a ransom note named “how_to_back_files.html” containing the following message:



To restore files you will need a decryptor!.
To get the decryptor you should:
Pay for decrypt your network – 12 BTC :
Buy BTC on one of these sites
Send 12 BTC for decrypt
Send screenshot of payment to [email protected] or [email protected]. In the letter include your personal ID (look at the beginning of this document).


Only our team can decrypt your files.
No Payment = No decryption!
You really get decryptor after payment. As a guarantee you can send 1 test image or text file on our email (In letter include your personal ID)
Do not attempt to remove program or run any anti-virus tools! This doesn’t help 🙂
Decoders of other users are not compatible with your data, because each infected computer have unique encryption key!!!
Attempts to self-decrypting files will result in the loss of your data”

How does Badday ransomware proliferate?

Badday ransomware may proliferate via spam emails containing an infected attachment or corrupted link. Crooks mostly attach infected files in emails containing malicious scripts used to install crypto-malware like Badday ransomware in the system.
