Distribution of Noos Virus
Noos virus is a new data locker ransomware that has been released in active attack campaigns against computer users worldwide. The threat could be utilizing common tactics of distribution to infect computer systems.
One of the easiest ways for the criminals to spread the payload of Noos 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 Noos crypto virus. Another 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 Noos 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 Noos 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.
