Distribution of Zenis Ransomware Virus
Zenis virus is a new data locker ransomware that has been released in attack campaigns against computer users worldwide. The threat could be utilizing widely used tactics of distribution to infect computer systems.
One of the easiest ways for the criminals to spread the payload of Zenis ransomware is by attaching it to email messages that are later released in active attack campaigns. The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files which users open without hesitation. Once opened on a target host these compromised files trigger the ransomware payload and infect the device with Zenis crypto virus. Other infection tactic related to emails is hyperlink inserted in the content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest.
Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including Zenis virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.
The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind Zenis virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious add-ons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.
Impact of Zenis Ransomware Virus
A crypto virus called Zenis has been spotted to harass online users. It appears to be a new threat that has been made by an unknown hacker or criminal collective. The security analyses of its samples are still ongoing but eventually, some of the captured samples showcase that the virus infiltrates the infected computers on a deep level.
The Zenis infection virus incorporates different components that can initiate the following changes to the compromised machines:
- Data Harvesting — The Zenis virus can be designed to gather information about the infected computer and its user. It may be anonymous in nature by including only values related to the hardware components. Another instance is the harvesting of personal data that can directly reveal your identity. This is done by looking out for strings related to personal names, addresses, telephone numbers, location, interests and passwords.
- Stealth Protection — It is possible that Zenis virus has the functionality to remain hidden on the system. Thus, it can be invisible to any installed anti-virus software, sandbox and debug environments, as well as virtual machine hosts. In addition, if any of them are found the ransomware can bypass detection and remove them altogether. In certain cases the malware can be programmed into deleting itself if it is unable to bypass the protection.
- System Modification — Changes to the operating system can make the virus sample a persistent threat. This means that the malware code can interact with the operating system and make manual removal difficult for the end users.
Afterward, the infection initiates a scan of all drives to locate target files and encrypt them with strong cipher algorithm. Zenis is likely to corrupt files that store important information like documents, images, videos, music, text files, databases, and other. After Zenis ransomware encrypts a file that file receives the Zenis- prefix. And after the dash, two symbols will be added. In addition, ther threat appends a base64 extension appended to each file. As a result 12 more symbols (A-Z, 0-9) will be placed as an extension.
At the end it drops a ransom note to extort a ransom payment from victims. It is called “Zenis-Instructions.html”. Below you can see all what it reads:
