How Does .Gryphon Virus Infiltrate the System?
The .Gryphon virus can be distributed to targets using the different delivery methods. One of the primary ones is the coordination of mass email spam messages. They can be of several different types:
- Attachments ‒ The .Gryphon virus can be distributed as an attachment to the messages. The body content can contain social engineering tricks that can make the targets download and execute the strains.
- Malicious Hyperlinks ‒ Links that lead the users to infected binaries can be inserted in the body contents of the message.
- Combination ‒ Many email templates rely on using both methods to increase the infection ratio.
Usually the hacker operators aim to create messages that pose as being by a legitimate service or institution. Different social engineering tricks are used to make the victims infect themselves with the virus. Other .Gryphon virus distribution methods include the use of infected software installers. They are usually legitimate installers that have been downloaded from their official sources and modified by the hackers to include the .Gryphon virus code. They are then distributed on hacker-controlled portals and P2P networks. In most cases the malicious sites may use graphics and text to confuse the users into believing that they are downloading the real software.
Another source of .Gryphon virus instances can be a browser hijacker campaign. This is when malicious browser extensions lead to malware infections. Upon installation these plugins change important settings: the default home page, search engine and new tabs page to point to a hacker-provided URL. During the infection phase the malware can be delivered. As a consequence of the redirect the victims can have their security and privacy seriously affected as tracking cookies and web scripts are employed. They can be used to harvest sensitive user data: bookmarks, history, cookies, settings, form data and passwords.

Infection Flow of .Gryphon Virus
The .Gryphon virus is an advanced ransomware strain that has just been detected in an ongoing hacker attack. The security experts who reported it state that it contains code sourced from the BTCWare malware family. This means that the hackers behind it are probably either connected with the criminals behind prior attacks or have obtained the source code from the hacker underground markets.
The .Gryphon ransomware attacks follow the behavior patterns set by other related strains. When the infection has been initiated one of the first steps is to modify important system settings. This includes the Windows registry, the virus has been found to modify essential entries. Depending on the strains it may even institute a persistent state of execution. This means that the .Gryphon virus engine will monitor all user actions and system commands to effectively block manual removal attempts.
The ransomware starts its virus engine as soon as the initial infection is confirmed. Depending on the acquired strain the .Gryphon virus targets different file types. A sample file list affects the following data:
1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw,
.css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf,

All affected data receive a .gryphon extension. Depending on the case different email address may be inserted, examples include [[email protected]].gryphon or .[[email protected]].gryphon. They are the hacker-provided contact addresses that the victims can use to write to the hacker operators.
A ransomware note is crafted in a HELP.inf or HELP.txt file. The collected samples show that the files contain the following message:
