What is a FATP file?

FATP files mostly belong to Fatpack, ASPack. The *.FATP file extension appears to be associated with at least two distinct file types based on observed occurrences. One type, accounting for approximately 30% of observed instances, involves JPEG image files (JPG) utilized as thumbnails. These files likely represent a partial or modified form of the standard JPEG format, potentially incorporating encryption or other data appending techniques. The second type, comprising roughly 18% of instances, consists of executable files (EXE) with appended data. This format is linked to software named "Fatpack", potentially an abbreviation of "Full Access to Patched Executable". This suggests a connection to software patching or modification, possibly involving tools like "ASPack", a known executable packer/protector. The presence of appended data within the executable file may serve various purposes, such as storing additional resources, configuration settings, or licensing information.

Note: Files with the .FATP extension are often associated with ransomware infections. This type of malware encrypts files on a victim's computer and appends the .FATP extension, rendering them inaccessible without a decryption key. Attackers typically demand a ransom in exchange for this key. You may find decryption tools on NoMoreRansom.org.
It is strongly recommended that you do not pay the ransom. Doing so does not guarantee file recovery and only encourages further criminal activity. Instead, report the incident to law enforcement and seek assistance from cybersecurity professionals.

4 Steps to Open an Unknown .FATP File

  1. Identify the Source: These files often come from software developers packing executables or users sharing compressed binaries, suggesting tools like ASPack or Fatpack were used.
  2. Check the Header: Open the file in a hex viewer to inspect the first few bytes:
    • "MZ" indicates a standard Windows executable.
    • "PK" suggests a ZIP-based compressed archive.
    • Unreadable binary data often implies a heavily encoded or packed file.
  3. Use the Original Software: You typically need the original program to run or unpack it; try ASPack, Fatpack, or simply ask the sender for the correct unpacking utility.
  4. Use this Webpage: Drag and drop your .FATP file into our viewer to detect its exact format, extract metadata, and preview readable text.
