Miscomputation when performing AES encryption in rust-crypto
The following Rust program demonstrates some strangeness in AES encryption - if you have an immutable key slice and then operate on that slice, you get different encryption output than if you operate on a copy of that key. For these functions, we expect that extending a 16 byte key to a 32 byte k...

Swift Sensors Gateway device password generation authentication bypass vulnerability
Summary An authentication bypass vulnerability exists in the device password generation functionality of Swift Sensors Gateway SG3-1010. A specially-crafted network request can lead to remote code execution. An attacker can send a sequence of requests to trigger this vulnerability. Tested Version...
North Korean Hackers Return with Stealthier Variant of KONNI RAT Malware
A cyberespionage group with ties to North Korea has resurfaced with a stealthier variant of its remote access trojan called Konni to attack political institutions located in Russia and South Korea. "The authors are constantly making code improvements," Malwarebytes researcher Roberto Santos said...
Shellcode-Encryptor - A Simple Shell Code Encryptor/Decryptor/Executor To Bypass Anti Virus
A simple shell code encryptor/decryptor/executor to bypass anti virus. Note: I have completely redone the work flow for creating the bypass, I have found injecting the binary into memory using PowerShell as the most effective method. Purpose To generate a .Net binary containing base64 encoded, AE...
