.jamper Ransomware – Distribution Techniques

The .jamper ransomware is a new virus that is being distributed by an unknown hacking collective. No information is available about their identity at the moment. As the attack campaign is relatively small we anticipate that the released samples are still an early test phase. In this situation any one of the popular delivery tactics can be use to spread the samples.

One of the main delivery tactics is the use of phishing email messages which are being sent out in a SPAM like manner to the intended recipients. They pose as legitimate notifications and letters from companies, services and products and coerce the user into interacting with the built-in contents. The virus file can alternatively be directly attached to the emails.

The other mechanism is to create malicious web sites that pose as legitimate sources of software. The .jamper ransomware files are uploaded there and disguised as real and useful programs. These sites frequently are hosted on domains that have an almost identical name to popular portals and may even integrate self-signed security certificates.

In many cases the infections can be caused by interacting with payload carriers — there are two main types which are the following:

  • Malicious Documents — Macros inserted into documents across all popular formats can lead to the .jamper ransomware infections: spreadsheets, databases, text files and presentations. Whenever they are opened by the victim users a notification prompt will ask them to enable the built-in scripts in order to correctly view the contents.
  • Application Setup Files — The hackers can embed the necessary code into the application installers. This is done by taking the original files from their official sources and adding in the necessary code. Popular examples include system utilities, creativity suites, office and productivity productivity tools and etc.

These files can also be shared on file-sharing networks such as BitTorrent. They are both used to distribute legitimate and pirate content.

Large-scale attacks can be caused using browser hijackers which are dangerous plugins made for the most popular web browsers. They are posted on the relevant repositories with user reviews and developer credentials. The displayed description offers new feature additions and performance optimizations.

.jamper Ransomware – Detailed Analysis

The .jamper ransomware at the moment contains only the base ransomware engine. We anticipate that this is due to the early version of the threat. Future releases can be programmed to cause a variety of malicious actions:

  • Security Bypass — One of the first engines that are run as soon as an infection has been made is the security bypass function. It will search the hard disk contents and memory processes for any security software that can block the activity of virus: anti-virus programs, firewalls, intrusion detection systems and virtual machine hosts.
  • Identity Theft — The .jamper engine can launch a module that can extract sensitive information about victim users. This is done by searching for strings such as their name, address, phone number, interests and any stored account credentials.
  • Unique Machine ID Generation — Every infected computer can be assigned with an unique ID which is generated by a special module. It takes its input values from sources like the installed hardware components, user settings and certain system variables.
  • Windows Registry Changes — The .jamper engine can also be programmed to cause major changes to registry values of both the operating system and third-party applications. This can lead to severe performance issues, data loss and unexpected errors.
  • Persistent Installation — If the hacker operator have enabled this function the .jamper ransomware will start automatically as soon as the computer is turned on. In most cases this also prevents the victims from using manual user removal guides as access to the recovery boot menus may be blocked.
  • Additional Payload Delivery — Ransomware infections can be programmed to deploy other threats to the infected computers. Common ones include miners, Trojans and redirects.

It is very possible that additional changes and add-ons can be added.

.jamper Ransomware – Encryption Process

Like other popular malware samples the .jamper ransomware will launch the encryption engine once all prior modules have finished running. It will probably use a built-in list of target file type extensions which are to be processed by a strong cipher. An example list can include the following data types:

  • Backups
  • Databases
  • Archives
  • Images
  • Music
  • Videos

All affected files are renamed with the .jamper extension. A ransomware note will be produced in a text file called “—README—.TXT”.
