Distribution of .vpgvlkb virus

The .vpgvlkb 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 .vpgvlkb 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 .vpgvlkb virus infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the .vpgvlkb 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 .vpgvlkb 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 .vpgvlkb virus

The .vpgvlkb virus is a sample of the Magniber ransomware which has been reported by the security community. This threat is one of the most dangerous infections in the last few months and it still continues to target the same group of computer users ‒ those from South Korea. One of the most dangerous aspects associated with it is the fact that the Magnitude exploit kit is the same weapon used to deliver a large part of the Cerber ransomware strains. So far the larger part of the .vpgvlkb virus samples infect primarily through automatically generated malware email messages.

The security experts note that the hacker operators behind the threat attempt to exploit a vulnerability that is being tracked as CVE-2016-0189 which is also used by other exploit kits such as Disdain and Sundown. Its description reads the following:

The Microsoft JScript 5.8 and VBScript 5.7 and 5.8 engines, as used in Internet Explorer 9 through 11 and other products, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka “Scripting Engine Memory Corruption Vulnerability,” a different vulnerability than CVE-2016-0187.

Once the initial infection has made the initial infection the .vpgvlkb virus starts to execute its complex attack scheme. It can be configured depending on the target users and computers however to a larger extent it combines several important modules that can be activated. They can be uploaded and activated upon the victim machines. Examples include the following components:

  • Virus Infections ‒ The .vpgvlkb virus can be used to deliver additional threats to the victim computers.
  • Information Harvesting ‒ One of the first malware actions taken by the infection engine is to conduct a thorough data harvesting process. This may include a system analysis comprising of the hardware components, installed software and user settings. In other cases the criminals may opt to steal sensitive files, including financial documents and private photos.
  • Spying Module ‒ The criminals behind the ransomware can include a fully-featured Trojan component which would allow them to spy on the victims in real time, as well as record their mouse movement and keystrokes. Depending on the case they may also be able to take over control of the machine at any given time.
  • Stealth Protection ‒ Some versions of the .vpgvlkb virus are able to protect themselves from virtual machines, debugging environments and sandboxes.

At the onset of infection the main .vpgvlkb virus files are immediately copied to a temporary folder to prevent manual user removal. Unlike other similar threats the base engine actually changes the names of all associated files with random files so that the malware data cannot be spotted using a regular scan. Some versions of the .vpgvlkb virus have the ability to install themselves as a persistent threat. This means that their infection engine will actively monitor the users actions and protect itself from removal.

Other malware actions that have been found to be carried out by the .vpgvlkb virus are related to process creation. The security analysts discovered that the malware enginr is able to create many processes with different privileges of its own, as well as “hook” itself to both running apps and Windows services. This makes it very easy to carry out complex attack scenarios. In addition .vpgvlkb virus samples are also known to be able to execute commands as instructed by the hackers.

A possibility is the launch of windows and pop-ups from legitimate and widely used applications such as web browsers. The advanced infection capabilities means that the hacker operators behind the .vpgvlkb virus have the ability to modify important settings in a manner similar to hijackers. Modifications include the following: default home page, search engine and new tabs page which can all point to a hacker-designated address. In addition the .vpgvlkb may be used to extract valuable information from the browsers as well: any stored cookies, history, bookmarks, settings, passwords and account credentials. Similar viruses can impact the most widely used browsers: Google Chrome, Mozilla Firefox, Opera, Safari, Microsoft Edge and Internet Explorer.

Once all preliminary conditions have been met the ransomware process is started. Like the base threat this strain also uses the same old list of target file type extensions which includes the following data:
