What is a MICRO file?

A file with the .micro extension is a file that has been renamed and encrypted by TeslaCrypt 3.0 ransomware. It could be a document, image, video game data, or other file. Typically, the .micro extension is added to the file's normal extension, resulting in a file with an extension like .docx.micro. You can decrypt .micro files for free using TeslaDecoder.

More Information

TeslaCrypt is a form of ransomware that infects users' computers using an Adobe Flash exploit. TeslaCrypt's creators produced several versions of the ransomware, which use different types of encryption and target different types of files. TeslaCrypt 3.0 primarily targets Word documents, PDFs, JPEG images, and game data files, encrypting them and appending them with the .micro, .xxx, or .ttt extensions.

In May 2016, TeslaCrypt's creators shut down the ransomware and released master decryption keys for each version. BleepingComputer forum user BloodDolly added these keys to his TeslaDecoder decryption utility, allowing users to decrypt files encrypted by TeslaCrypt.

How to open a MICRO file

FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
