Static and Dynamic AnalysisStatic and dynamic analysis are two primary techniques used in malware analysis and reverse engineering to study the behavior of software, particularly malicious software, without or with execution, respectively. Here’s a breakdown of their differences, along with tools commonly used for analysis, such as VirusTotal, Reverse.it, and Hybrid Analysis.1. Differences Betwe..

Decompiling and ReversingDecompiling and reversing engineering are techniques used to analyze and understand compiled software. These methods allow researchers (and attackers) to examine how a program works, identify vulnerabilities, and sometimes bypass protections. In response, many developers employ obfuscation to make reverse engineering more difficult. Here’s an overview of decompiling, cod..

Malware FeaturesHere’s a breakdown of these malware features and techniques commonly used to enhance their effectiveness and persistence.1. Remote Code Execution (RCE)Malware often employs RCE methods like buffer overflow, SQL injection, or exploitation of unpatched vulnerabilities, allowing attackers to execute arbitrary code on the target system remotely.2. Domain-FluxDomain-flux dynamically g..

Do not Blame the UserThe principle of “Do not blame the user” emphasizes that the responsibility for maintaining security lies with the system and its designers, not with the end users. Security should empower and protect users by creating systems that are intuitive, resilient, and trustworthy, instead of punishing or blaming individuals for mistakes or failures in security practices.1. Why Blam..

Interesting MalwareThese malware instances highlight various approaches to cyber threats, from network worms to sophisticated supply chain attacks. Each had a unique impact, changing how we view and respond to cyber threats.1. ConfickerFirst detected in 2008, this worm exploited Windows OS vulnerabilities, forming a large botnet.It spread via network shares and removable media, affecting million..

Insecure by Exception“Insecure by exception” refers to the practice of making deliberate exceptions to security policies or controls to enable certain activities necessary for a job or task. While exceptions can be necessary to maintain productivity or meet operational needs, they introduce vulnerabilities or weaken security in specific areas. The challenge lies in managing these exceptions effe..

Mandatory Access Control (MAC)Mandatory Access Control (MAC) is a security model that enforces strict access control policies determined by a central authority. Unlike discretionary access control (DAC), where users or resource owners determine access permissions, MAC is managed system-wide and based on predefined rules.1. What is MAC?Definition: MAC is a method of regulating access to resources..

EncryptionEncrypting software and firmware components is a security practice used to protect these critical assets from unauthorized access, reverse engineering, tampering, and malicious exploitation. This ensures confidentiality, integrity, and authenticity throughout the software or firmware lifecycle.1. Why Encrypt Software and Firmware?Protect Intellectual Property (IP): Encryption safeguard..

Compiler Security FeaturesModern compilers incorporate various security features to mitigate vulnerabilities during the software development process. One notable feature is their ability to detect and handle buffer overruns at compile time or runtime, which are common vulnerabilities exploited in attacks like stack smashing or heap corruption.1. Buffer Overrun VulnerabilitiesDefinition: A buffer..

Code SigningCode signing is a cryptographic process that ensures the authenticity and integrity of software by digitally signing it with a certificate issued by a trusted Certificate Authority (CA). It provides assurance that the code comes from a verified publisher and has not been tampered with after it was signed.1. Purpose of Code SigningAuthenticity: Verifies the identity of the software pu..
