In cryptography, black-box obfuscation was a proposed cryptographic primitive which would allow a computer program to be obfuscated in a way such that it was impossible to determine anything about it except its input and output behavior. [1] Black-box obfuscation has been proven to be impossible, even in principle. [2]
In 2001, Barak et al., showing that black-box obfuscation is impossible, also proposed the idea of an indistinguishability obfuscator, and constructed an inefficient one. [8] [7] [2] Although this notion seemed relatively weak, Goldwasser and Rothblum (2007) showed that an efficient indistinguishability obfuscator would be a best-possible obfuscator, and any best-possible obfuscator would be ...
Dotfuscator is a tool performing a combination of code obfuscation, optimization, shrinking, and hardening on .NET, Xamarin and Universal Windows Platform apps. Ordinarily, .NET executables can easily be reverse engineered by free tools (such as ILSpy, dotPeek and JustDecompile), potentially exposing algorithms and intellectual property (trade secrets), licensing and security mechanisms.
In software development, obfuscation is the practice of creating source or machine code that is intentionally difficult for humans or computers to understand. Similar to obfuscation in natural language, code obfuscation may involve using unnecessarily roundabout ways to write statements. Programmers often obfuscate code to conceal its purpose ...
Hardware Obfuscation can be of two types depending on the hardware platform targeted: (a) DSP Core Hardware Obfuscation - this type of obfuscation performs certain high level transformation on the data flow graph representation of DSP core to convert it into an unknown form that reflects an un-obvious architecture at RTL or gate level.
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
Obfuscated TCP (ObsTCP) was a proposal for a transport layer protocol which implements opportunistic encryption over Transmission Control Protocol (TCP). It was designed to prevent mass wiretapping and malicious corruption of TCP traffic on the Internet, with lower implementation cost and complexity than Transport Layer Security (TLS).
njRAT, also known as Bladabindi, [1] is a remote access tool (RAT) with user interface or trojan which allows the holder of the program to control the end-user's computer. It was first found in June 2013 with some variants traced to November 2012.
