Congratulations on completing this mini-module. We've successfully traversed a range of topics, from Bluetooth hacking and cryptanalysis side-channel attacks to microprocessor vulnerabilities. We've explored the historical and contemporary facets of Bluetooth attacks, gaining insights into attacks such as Bluesnarfing, Bluejacking, BlueSmacking, Bluebugging, BlueBorne, KNOB, and BIAS. This understanding equips us with the knowledge to identify and defend against such threats. In our exploration of cryptanalysis side-channel attacks, we've unveiled the principles of cryptanalysis and learned about various side-channel attacks like timing attacks, power-monitoring attacks, and acoustic cryptanalysis. This knowledge is essential for understanding the potential threats in cryptographic systems that go far beyond their software implementation. Lastly, we examined the Spectre and Meltdown vulnerabilities and gained insights into the mechanisms that enabled them and how to mitigate them.

👩🎓👨🎓 CSAW 2023 Embedded Security Challenge (ESC) is open for registration!   This year's ESC focuses on side channel attacks (SCA) on cyber-physical systems (CPS). Cyber-physical systems are used by hundreds of industries and in many critical infrastructure systems. If these CPSs are not properly setup they can leak information even if they are using cryptographically secure software. This year, teams will investigate a range of SCAs on an Arduino Uno based CPS running several firmware that expose various side channels.   The event comprises a qualification and a competition phase where teams will be able to explore several variations of a CPS and exploit side channels they find while suggesting mitigations for the found exploits.   Registration and information here: https://lnkd.in/gMBmfDjV #csaw #cybersecurity #europe

A groundbreaking side-channel attack method that poses a risk of #dataleakage has been unveiled, targeting nearly all modern CPUs. Conducted by an esteemed group of eight researchers representing Technische Universität Graz in Austria and CISPA Helmholtz Center for Information Security in Germany, this cutting-edge research team includes experts who previously discovered the infamous Spectre and Meltdown vulnerabilities, along with several other side-channel attack methods. Dubbed Collide Power, the newly identified attack exhibits similarities to the notorious Meltdown and Microarchitectural Data Sampling (MDS) vulnerabilities. While this discovery raises concerns, rest assured that the #cybersecurity community is actively working on preemptive measures.

#Day16 - Imaging QUME Virtual Machine on Raspberry Pi4 - Hello Cyber Team! I have been doing a lot of research on imagining QUME virtual machine on my Raspberry Pi4 B desktop. I tried out some different commands in the terminal and when it came to identifying and adding the Kernel path, BIOS information, I became quite confused. Thankfully, I will be connecting with my mentor tomorrow. Be safe everyone and happy cybering! ⌨ #cybersecurity #cybertechdave100daysofcyberchallenge

We recently hosted a fascinating talk by Annika Wilde, PhD candidate at Ruhr University Bochum, on securing next-generation platforms. Annika discussed forking attacks and mitigations in trusted execution environments (TEEs) based on Intel Software Guard Extensions (SGX) and examined the impact of cloning attacks on SGX enclaves. She shared a case study that thoroughly analyzes 72 SGX-based proposals for reducing the susceptibility of SGX enclaves to cloning attacks. The case study also provides ideas to improve the security of TTP-based anti-forking solutions. #NECLabs #cybersecurity #cloudcomputing

I leveraged the Parrot OS, a highly respected and versatile operating system, to tackle various challenges on platforms such as TryHackMe, HackTheBox, and Capture The Flag (CTF) exercises. I particularly enjoyed the Popcorn, Bashed, and Forest challenges on HackTheBox. To analyze and resolve these challenges, I utilized a range of tools, including Ida Pro, x64dbg, LARA, Cheat Engine, Cutter, Radare2, exDnSpy, and Ghidra, which allowed me to hone my skills in assembly language on multiple architectures, including arm, x64, and x86. These tools enabled me to thoroughly explore and dissect malware, further enhancing my skills in reverse engineering and problem-solving, all within the context of cyber security.
