The .norvas ransomware is a new release of the STOP/DJVU family of threats which is being spread against users worldwide using the most popular tactics. We anticipate that as the hacking groups continue with the attack campaigns more and more victims will get affected. At the moment there is no information available about the hackers and we cannot judge if they are the creators of the new STOP sample or the .norvas ransomware is ordered through a customization service on the dark underground markets.
The most common distribution tactics remain the construction and coordination of web sites that pose as legitimate and safe Internet sites across all popular types: search engines, web portals, download pages and etc. A similar technique is the creation of phishing emails which imitate well-known companies and services and their common notification messages. By interacting with the displayed content or attached files the .norvas ransomware infection can be started.
The virus installation files can also be found within payload carriers of which there are two popular variants: malicious documents and software installers. All virus files can then be uploaded to file-sharing networks such as BitTorrent which are widely used to share both legitimate and pirate data. A common tactic is to embed the virus installation scripts in browser hijackers — dangerous plugins which are commonly found across the relevant repositories and posted with fake user reviews and developer credentials.
As soon as the actual .norvas ransomware is launched the built-in sequence will be launched. Like other similar STOP virus samples it may start an information gathering module which is designed to acquire data that can both identify the machines and the users themselves. This can be used to expose the identity of the users and carry out crimes like identity theft and financial abuse. The given ID to the machines allows every single affected computer to be identified by the hacker. This information can be used further by the next module called security bypass which will scan the memory contents and hard disk for the presence of any software that can block the ransomware’s correct execution. The list of target apps includes anti-virus engines, firewalls and virtual machine hosts.
When the computer has been bypassed and infiltrated various malware actions can take place, some of the most common ones are the following:
- Additional Malware Installation — Many STOP variants can be configured to deploy other threats to the compromised computers. Examples include all kinds of Trojans, miners, hijackers and etc.
- Windows Registry Modifications — The engine can modify existing strings that belong to the installed services and third-party applications. This can lead to data loss, unexpected errors and severe performance issues.
- Boot Options Changes — The .norvas ransomware can also change the system settings in order to automatically launch itself as soon as the computer is started.
When all components have executed correctly the ransomware engine can be called. Using its built-in engine a preset list of target file type extensions will be processed with a strong cipher. In the end the affected data will be renamed with the .norvas extension and a ransomware note or lockscreen instance will be applied in order to blackmail the victims into paying the hackers a decryption fee.
