![]() In November 2015, a partnership between the Trend Micro Forward-Looking Threat Research team and the National Crime Agency of the UK led to the shutdown of and Cryptex Reborn, popular sources of crypting services. It also supports file encryption and decryption. It supports encryption and decryption of text entered into the programs input fields. It has been developed to provide an easy access to GPG encryption and decryption. Trend Micro works with public and private institutions to take down sites that offer crypters and other malicious tools. GPG- Crypter is a graphical front-end to GnuPG (GPG) using the GTK3 toolkit and GPGME library. Unknowing users open the program, which will force the crypter to decrypt itself and then release the malicious code. A crypter is a type of software that can encrypt, obfuscate, and manipulate malware, to make it harder to detect by security programs.They send these programs as part of an attachment in spear phishing emails and spammed messages.They use crypters to encrypt a malicious program then reassemble the code into an actual working program. There is a free version but it's very limited and perhaps best thought of as a way to trial the software and help become used to the interface and basic functions.Cybercriminals create crypters or buy them on underground markets.Crypters are available in the Russia, China, Germany, the U.S., and Brazil cybercrime underground markets. In a 2016 research on cybercrime and the Deep Web, Trend Micro found that crypters can be bought in various underground markets worldwide.
