A decade ago, academic researchers demonstrated how computer memory remanence could be used to defeat popular disk encryption systems[1]. Today, most seem to believe that these attacks are too impractical for real world use. Microsoft has played down the threat of memory remanence attacks against BitLocker using words such as "they are not possible using published techniques"[2].
We will show techniques that allow recovery of BitLocker encryption keys from RAM on most, if not all, currently available laptops and tablets. These techniques allow bypassing of security controls such as password protected BIOS configuration, UEFI-based Secure Boot and the TCG Platform Reset Attack Mitigation by directly manipulating the firmware storage device (EFI SPI flash chip).

Fuzzing and You: Automating Whitebox TestingNetSPI
Fuzzing is easy, but getting useful information from fuzzing isn’t. ‘Spray and pray’ might get some results, but a set of well-designed tests will get much better results faster. Unfortunately, the job doesn’t end there. Fuzzing doesn’t find vulnerabilities; fuzzing finds unexpected behavior. Interpreting that unexpected behavior relies on understanding the application you’re fuzzing and the tests you’ve designed. This presentation will discuss techniques for creating tests targeted towards uncovering specific behavior, including authorization bypasses, directory traversals, and buffer overflows.

Finally, it discusses some methods that viruses use to avoid detection by antivirus software, such as killing antivirus tasks, self-modification, and encryption with variable keys.
PC maintenance involves activities to keep computers running properly such as cleaning, backups, disk maintenance, and software updates. It includes preventive maintenance to avoid problems and corrective maintenance to fix existing issues. Regular maintenance saves money and time by preventing problems and safeguarding data. Common maintenance tasks include cleaning interior and exterior components, backing up important files, disk maintenance like defragmenting, and updating software and virus definitions.
Software utilities are programs used by system administrators to maintain and improve system performance. They help solve problems and recover data. Backup utilities allow users to backup or recover systems by creating incremental, differential, or full system backups. Security utilities like antivirus, antimalware, and firewall programs help secure the computer by blocking viruses, malware, and unauthorized access. Disk utilities, such as disk clean up and defragmentation, improve system performance by deleting temporary files, rearranging data location, and freeing up storage space.
Diagnostic software tools are used to identify problems on a computer or piece of equipment. They test onboard systems to detect issues and alert users of potential problems or breakdowns. Some common downloadable diagnostic tools include programs that protect against malware, repair registry errors, improve system performance and stability, clean the registry, and tune up and maintain PCs with functions like anti-spyware and privacy protection. Disk management tools allow users to format drives, check for physical errors, optimize disk space usage, remove unused files, create partitions, and scan operating system files.
