Nuksus Virus (STOP Ransomware) – More About the Infection
Security researchers reported that the Nuksus virus is based on the code of one of the most popular ransomware families dubbedSTOP. The spread of Nuksus ransomware is happening with the help of spam emails, email attachments, hacked web pages, and corrupted freeware installers.
Since malspam (emails that deliver malicious code) enables hackers to spread their ransomware on a large scale, they often bet on it. For its realization, hackers usually embed the malicious code in files of well-known types and then attach these files to email messages. The emails usually state that the attached files as:
- Invoices coming from reputable sites, like PayPal, eBay, etc.
- Documents from that appear to be sent from your bank.
- An online order confirmation note.
- Receipt for a purchase.
Once activated on your system Nuksus virus creates a bunch of malicious files and places them in folders like %AppData% and %LocalAppData%. With the help of newly created malicious files the ransomware corrupts essential system settings and becomes able to encrypt target files.
For the encryption of target files Nuksus virus launches a built-in cipher module that is designed to scan selected folders for predefined types of files. Every time the module detects a target file, it utilizes a sophisticated cipher algorithm to transform its code. Unfortunately, the threat is likely to corrupt all files which store valuable information. Hence, encrypted may be:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Following encryption files cannot be opened. In addition, they have the extension .nuksus at the end of their names. In fact, the main goal of this ransomware is to blackmail you into paying a ransom to hackers. That’s why Nuksus drops a ransom message with instructions on how to complete the ransom payment process.
