This document discusses fault injection attacks on secure boot implementations in embedded systems. It begins by explaining how secure boot works, using a hardware root of trust to verify that only authorized code is executed. It then introduces different methods of fault injection, such as voltage manipulation and electromagnetic interference, that can corrupt code verification and execution. Examples are given of how faults could bypass signature checks or modify execution. Countermeasures at both the software and hardware level are outlined to make systems more robust against fault injection. The document concludes that while hardware roots of trust increase security, physical attacks still remain a threat, and both hardware and software countermeasures are needed to protect against fault injection in secure embedded systems.

This document discusses best practices for implementing a successful security awareness program at an organization. It recommends starting with a 3-month plan, using various communication methods like newsletters and lunch presentations tailored to your employees. Metrics like incident reports before and after should be measured to assess impact. Gaining support from other departments and leadership is also key. The focus should be on building a positive security culture through education rather than directives.

This document discusses exploiting vulnerabilities in the BlackBerry WebKit browser to achieve code execution on BlackBerry devices. It describes using HTML5 spraying to organize the heap, leaking a pointer using another vulnerability, and chaining exploits like a integer overflow and heap overflow to redirect execution to injected shellcode. The document provides disassembly snippets and diagrams to explain the exploitation process and challenges of real devices versus simulators.

This document discusses exploiting vulnerabilities in PHP systems used by cybercriminals to manage exploit kits. It describes how exploit kits work and why attackers use PHP, noting that PHP systems often lack security protections. It then details methods for bypassing authentication on several exploit kit systems, including brute force cracking weak passwords, and exploiting vulnerabilities after authentication to gain remote code execution on the attackers' systems. Specific vulnerabilities are demonstrated for the Phoenix, Blackhole 2, and Sakura exploit kits. The document concludes that even exploit kits themselves can be vulnerable to "PHP injections" and other attacks given the large attack surface exposed after authentication.

Flame was one of the most complex cyber threats ever discovered. It used sophisticated techniques like man-in-the-middle attacks and intercepting Windows Update to infect systems. The attackers were able to forge digital certificates due to a weakness in the MD5 hash function, allowing them to disguise malware as legitimate Microsoft software updates. This presentation discusses Flame's technical capabilities and the challenges it posed for security professionals working to understand and mitigate the threat.

This document discusses memory forensics and the Volatility framework. It begins by distinguishing memory forensics from disk forensics and explaining why memory forensics is needed to analyze skilled attackers and advanced malware that aim to avoid disk artifacts. It then provides an overview of Volatility capabilities for analyzing processes, network connections, code injection techniques, and decrypting software-based encryption keys from memory captures. It emphasizes that memory forensics can recover important evidence that is never written to disk.
COLD WAR POLITICS
The document summarizes key events of the Cold War era Cuban Missile Crisis. In 1961, Soviet leader Nikita Khrushchev placed nuclear missiles in Cuba to counter U.S. threats. Three weeks later, American reconnaissance discovered the missiles. President Kennedy ordered a naval blockade of Cuba and threatened military action if Soviet ships approached. A confrontation was averted when Khrushchev agreed to remove the missiles to end the 13-day crisis, avoiding nuclear war but increasing Cold War tensions.

The ZeroAccess botnet infects over 2 million computers globally and has over 200,000 active super nodes. It generates revenue through ad click fraud and bitcoin mining, costing advertisers up to $1 million per day. The botnet has evolved over time to become more resilient and difficult to detect and remove. Coordinated efforts are needed between antivirus companies, internet service providers, and researchers to help weaken the botnet through techniques like detecting and blocking its command and control channels.

This document discusses security issues with OAuth 2 implementations and provides recommendations. It summarizes two cases where incomplete OAuth 2 implementations led to security compromises: Facebook used the implicit flow, allowing access tokens to be passed in URLs and accessed by any site; foursquare's native app passed access tokens to its backend API, allowing impersonation. The document recommends using OpenID Connect for OAuth SSO to add audience restrictions and protecting against token swapping, and using the OAuth assertion flow to authenticate native apps securely.
Planejamento em Mídia Alternativa
O documento discute jornalismo comunitário e mídia alternativa, sugerindo que os jornalistas inovem para alcançar seu público onde ele está, ao invés de publicações tradicionais. Ele fornece exemplos de publicações em banheiros femininos de universidades e outras mídias acessíveis às comunidades locais. O documento também descreve o processo de planejamento, produção, circulação e feedback para jornalismo comunitário em mídia alternativa.
Flor del membrillero
El membrillero es un árbol frutal originario de Asia. Sus flores son muy fragantes y atraen a insectos polinizadores como abejas y mariposas. La fruta del membrillero, llamada membrillo, es comestible y se usa comúnmente en postres y mermeladas.
Tigre Siberiano Oscar
El tigre siberiano solía habitar gran parte de Asia, pero ahora se limita a una pequeña zona del sureste de Rusia debido a la destrucción de sus hábitats forestales por la industria maderera y la caza furtiva. Acecha a su presa en silencio y la mata de un mordisco antes de arrastrarla al bosque. Las hembras dan a luz entre 2 y 4 cachorros cada 3 años que dependen de ella por unos dos años antes de independizarse. Su supervivencia depende de proteger los bosques primarios que necesita
Jean goodall
Jane Goodall y Dian Fossey fueron dos importantes primatólogas que estudiaron a chimpancés y gorilas respectivamente. Goodall descubrió que los chimpancés tienen cultura y transmiten conocimientos de generación en generación, mientras que Fossey pasó 22 años estudiando a los gorilas de las montañas y demostró que no son tan violentos como se creía. Ambas científicas hicieron importantes contribuciones al estudio del comportamiento animal.
