![]() He usually carries a handgun, throwing knives, and a garrote, but at times he relies on his hand-to-hand combat skills rather than using a weapon. ![]() Abilities Īlex is a cryptozoologist focusing on reptiles and related cryptids, including gorgons, basilisks, and cockatrice. He feels uncomfortable sitting back and letting the women do the domestic tasks he feels obligated to help. He does not like horses at all, having had a bad experience with some that were infected with lycanthropy. Sarah considers him, along with Elsie, as the more socially consious and sensitive of her cousins. He prefers to think through problems and study topics in depth. ![]() He tends to be calm, rational, and determined. Personality Īlex’s personality is shaped by his commitment to science. He needs glasses or contacts to see clearly, though he is not completely blind without them. K7 Labs continuously monitors such kinds of malware, tools and campaigns to provide effective protection against all of them. But the fact that it was submitted to VT only recently with the latest compilation time means someone is again working on it or at least evaluating it. Figure 9: Payload decryptionĬonsidering the time when the Kazy Crypter showed up, we can glean that it is pretty old and almost all the AV vendors have behaviour detections. Once the decryption is complete, it then invokes and calls the entry point of the payload to execute the same. Then it proceeds to decrypt the payload that was compiled using the Kazy Crypter and stores it in an array as depicted in Figure 9. Figure 7: Decryption key and resource name passed as parameters Then it loads the PNG data in the resource and retrieves the required byte from the image and stores it in an array as depicted in Figure 8. Resname – resource name where encrypted content is present as a PNG fileĪrgs – string array to store the decrypted content The argument passed to the Start function are Figure 6: Creating delegate to execute the decrypted file Programmers often tend to use delegates when they need to pass a method as a parameter of another method. It is a reference type variable that holds reference to a method and that reference can be changed at runtime. Delegates are similar to pointers in C and C++ functions. It then creates a Delegate for the function which dynamically invokes and calls the Start function of the decrypted file Kazyloader.dll as depicted in Figure 6. The 1 st task of the binary upon execution is to decrypt the PE loader’s DLL file name Kazyloader.dll stored in an array as depicted in Figure 5. Once the file is built and compiled, we receive a file which is a minimum of 70KB size and varies depending on the functions you select. Figure 4: Other functionalities provided by the Crypter Figure 3: GUI of the CrypterĪpart from this, it also has a host of other functionalities for process persistence, registry persistence, BSOD on process termination, hiding files, delayed execution, file size pumping with random junk data, start-up location and self-copy to location like %Appdata%, %temp%, Program files etc., as depicted in Figure 4. The 1 st tab in the GUI has the option to input the file to be compiled with options such as whether to obfuscate, compress the file or use Anti-VM, Anti-Sandbox and Anti-Emulator functionalities as depicted in Figure 3. The GUI of the Crypter is quite straightforward and very simple to use. In 2021, the cracked version of the Crypter was seen being promoted in one of the underground forums as depicted in Figure 2. The Crypter was last seen on Hack Forums in 2018 with the price of 13 USD and by 2019 there was also a thread stating that the author doesn’t reply to his email and the crypter hosting site is down. This blog gives you the complete analysis of Kazy Crypter and its loader functionalities. Nowadays, though it’s not used very often, there was a submission of the Kazy Loader module to VT during the 1 st week of March along with the source code of Kazy Crypter. The cost of this crypter averages between 13 USD to 30 USD depending on the number of days it will be used and it is advertised as fully compatible with most of the well-known RATs available in the market such as LuminosityLink, NanoCore, etc. Kazy Crypter has been sold in many underground forums and markets since 2014.
