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

DeepSec 2020 Talk: RedTeamOps – Mert Can Coskuner, Caglar Cakici

Sanna/ October 3, 2020/ Conference

Red team operations involve many skills, the operation requires a lot of monitoring, consolidating and caution. In order to perform red team operations faster and stealthier, without thinking about the infrastructure, every team has its’ own habits and standards. However, there is a problem with those habits and standards: There are tons of tools but no operation management, No aggregation between these tools, When OPSEC fails due to problems above or any other reason, it’s essential to possess the capability of maintaining robust infrastructure which can be recreated if discovered, and more importantly, without any issues upon deployment. In this talk, infrastructure challenges we face as a red teamer will be discussed. Along with challenges, a solution will be proposed based on DevOps practices such as: Design your infrastructure based on the standards and

DeepSec 2018 Training: Advanced Infrastructure Hacking – Anant Shrivastava

Sanna/ November 5, 2018/ Conference, Training

Whether you are penetration testing, Red Teaming or trying to get a better understanding of managing vulnerabilities in your environment, understanding advanced hacking techniques is critical. This course covers a wide variety of neat, new and ridiculous techniques to compromise modern Operating Systems and networking devices. We asked Anant a few more questions about his training. Please tell us the top 5 facts about your training. Constantly evolving course: Every year each iteration has something new added to it. (Minimum 25%, maximum 50% of the course gets an upgrade every year). Developed by Practitioners: The course is developed by regular pentesters deriving challenges from real life pen-testing scenarios. All of our trainers are full time pentesters and part time trainers. Covers a whole breadth of infrastructure: From IPv4/v6 to databases, to OSINT, Windows, Linux,

Security in the Trenches (or how to get dirty and stay clean)

Mika/ February 27, 2012/ Security, Stories

Sometimes you have to get dirty, sometimes it’s fun to get dirty. No it’s not what might come to mind, it’s about the dirty business of information security: you have to break things to see if they are secure enough and to learn about weak points. But what to break? Your own systems? Someone else’s systems? Best is to stay clean when selecting your target for the dirty business (we talked about offensive security recently). Most fun are “Capture the Flags” challenges, also known as war-games, which are frequently offered to the security community to test abilities and learn new stuff. I recently found a CtF challenge that looked quite fun and we started a 2-day session at the Metalab, the Hackerspace in Vienna with a group of 6 or 7 people with different
