DeepSec 2025 Talk: How To Breach: From Unconventional Initial Access Vectors To Modern Lateral Movement – Benjamin Floriani & Patrick Pongratz

Sanna/ November 17, 2025/ Conference/ 0 comments

The perpetual cat-and-mouse game between attackers and defenders has pushed offensive security operators to innovate. While enterprise security teams have become adept at identifying and blocking malicious Office documents, suspicious executables, and known phishing URLs, a significant blind spot often remains: the gray area of “benign” file formats that are implicitly trusted by both users and security tools. This talk will arm attendees with the knowledge to identify and leverage these blind spots in red team engagements. We will begin by exploring the strategic shift from noisy, high-volume attacks to stealthy, low-profile techniques designed to circumvent modern EDR, email gateways, and web proxies. We’ll discuss why certain file types and delivery mechanisms succeed where others fail, focusing on the technical elements that make them effective. This includes exploiting the browser’s rendering engine and abusing

Sanna/ November 16, 2025/ Conference/ 0 comments

Managing GitHub security across all organizations and repositories within a company can be challenging. Mis-configured settings, hard-coded secrets, and outdated dependencies often go unnoticed, creating critical security gaps. In this session, we introduce an open source tool built to help companies secure their GitHub environments at scale. The tool runs security posture checks across organization and repository levels, scans for hard-coded secrets, performs Software Composition Analysis (SCA), validates security rule sets, detects misconfigurations, and generates a single comprehensive report. The report not only identifies risks but also provides actionable remediation steps, helping teams prioritize and address issues effectively. By using this tool, companies gain a complete view of their GitHub security posture across all organizations and repositories, making it easier to maintain strong security without adding complexity.

DeepSec 2025 Talk: Offensive SIEM: When the Blue Team Switches Perspective – Erkan Ekici & Shanti Lindström

Sanna/ November 15, 2025/ Conference/ 1 comments

Traditional SIEM solutions focus on detecting attacks—but what if we flipped the script? Instead of waiting for adversaries to act, defenders can use SIEM proactively to identify local privilege escalation risks before they’re exploited. By analyzing Sysmon and Windows event logs, blue teams can uncover hidden misconfigurations in services, scheduled tasks, DLL loads, and centralized application deployments that could allow an attacker to escalate privileges to SYSTEM. Sometimes, this approach might even reveal new CVEs lurking in your environment. This talk will showcase practical techniques for leveraging SIEM as an offensive discovery tool, helping defenders think like attackers to strengthen security from within. We asked Erkan and Shanti a few more questions about their talk. Please tell us the top 5 facts about your talk. SIEM is usually reactive. It can be used proactively

DeepSec 2025 Talk: Ransomware vs. Info Stealers: A Comparative Analysis – Steph Shample

Sanna/ October 23, 2025/ Conference/ 0 comments

This talk provides a clear and practical comparison between two dominant forms of malware: ransomware and information stealers. While both are used by threat actors to profit from compromised systems, their methods, visibility, and impact differ dramatically. We’ll start by defining each threat type and examining their primary objectives — ransomware aims for immediate financial gain through extortion, while info stealers quietly extract credentials, financial data, and other sensitive information for resale or future attacks. Worth noting is that Info stealers can and are often used as a precursor for a ransomware attack, connecting these two forms of malware in malicious operations. We’ll start by defining each threat type and examining their primary objectives — ransomware aims for immediate financial gain through extortion, while info stealers quietly extract credentials, financial data, and other sensitive

DeepSec 2025 Talk: Quantum Safe Cryptography: The Future of Cyber(un)security – Lukas Mairhofer

Sanna/ October 21, 2025/ Conference/ 0 comments

There is a cybersecurity threat looming that will change everything. Conveniently enough, it can be ignored until it is way too late to act: once available, Cryptographically Relevant Quantum Computers (CRQC) will effortlessly break asymmetric cryptographic algorithms such as RSA and ECC on which we build our current security infrastructure. In my talk, I will first discuss what makes Quantum Computers uniquely powerful, translating complex physical concepts into practical implications for cybersecurity. We will explore how Shor’s algorithm undermines current cryptographic assumptions and why digital signatures and public key infrastructures are particularly vulnerable. Attendees will gain an overview of the timeline for the development of CRQC, the principal actors in the field and why CRQC endangers our privacy already today. The session will then turn to mitigation strategies, exploring two promising paths: Quantum Key

DeepSec 2025 Talk: Fake News, Fake Pics: Securing Image Provenance in a Post-Quantum World – Maksim Iavich

Sanna/ October 16, 2025/ Conference/ 0 comments

With quantum computers on the horizon, today’s cryptographic defenses are running out of time. Fake news, deepfakes, and manipulated media already threaten digital trust, and quantum attacks will soon break the few remaining verification systems. Post-Quantum VerITAS is designed to secure digital content in both classical and post-quantum worlds, ensuring that image provenance remains verifiable even against adversaries with quantum capabilities. Our system combines lattice-based hash functions, post-quantum zk-SNARKs, and quantum-resistant digital signatures such as CRYSTALS-Dilithium. Unlike C2PA, which fails when images are modified or quantum attacks render its cryptography obsolete, Post-Quantum VerITAS provides a trustless, scalable, and quantum-secure solution. It enables real-time verification of images even after edits like cropping, resizing, or blurring, without requiring reliance on centralized authorities. In this talk, we will break down the cryptographic foundations of Post-Quantum VerITAS, demonstrate
