Distribution of CrY-TrOwX Virus
The CrY-TrOwX Virus is a new virus which has been sighted in a limited attack campaign. At the moment the security researchers cannot determine the primary infection strategy. We presume that the most widely used tactics are going to be employed.
Among them are the email messages created in an automated way and sent to large lists of potential victims. The CrY-TrOwX Virus can be directly attached to the messages. This is one of the easiest way for the criminals to attempt the infection. However a lot of email hosting providers usually capture the signatures of the virus and as such discard such messages or label them as dangerous or spam. Other infection methods related to this one is the option of inserting hyperlinks in the body content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest. Redirects can redirect to hacker-controlled sites, infected payloads or other instances that can lead to an CrY-TrOwX Virus infection.
The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the CrY-TrOwX 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 the CrY-TrOwX 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 addons 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 CrY-TrOwX Virus
The CrY-TrOwX virus is a newly discovered strain of the Hidden Tear malware family which has recently been spotted in a mass global campaign. The security analysts note that the captured samples contain signatures that link them to a developer known as ismail. Usually hackers like him/her download the original open-source code and tweak it to create their own versions.
At the moment the the CrY-TrOwX virus infections are rated as of low severity as they include only the ransomware component. As it does not contain much modified code its infection pattern and signature which makes it easy to identify and remove. However future versions of it can be include updates that can make it into a much more dangerous threat. For example an information gathering module can be initiated that is able to extract sensitive information from the hosts. Depending on the exact configuration the module may impact the machine itself by retrieving a list of the installed hardware components. The majority of ransomware versions actually tend to extract a list of the installed software. A combination of the gathered data is used to generate the unique infection ID (UID) which is used to identify every compromised host.
Consequently the next step would be to install a Trojan component which allows the hacker to spy on the victims in real time. As a consequence advanced versions can record the keystrokes and mouse movement in a database. Control of the infected hosts can be overtaken at any given moment.
A persistent installation of the CrY-TrOwX virus prohibits manual removal attempts by actively monitoring the users actions. Hidden Tear strains can aslo be made to change important settings of the operating system such as Windows registry values. As a consequence the users may experience performance issues, find out that certain apps stop working. In the majority of cases these changes also interfere with important Windows services.
Once all prerequisite conditions have executed the encryption phase begins. It uses a strong cipher to process the most widely used file type extensions: archives, documents, backups, images, music, videos and etc. A ransomware note is created in a READ_AND_CRY_.txt file that reads the following:
Hello All Your Important Files Are Encrypted by CrY!
Communicate With Us To Save Your Files!
E-Mail Address : [email protected]
The .locked extension is applied to all victim data.
