HäjySec March meetup

Welcome to the HäjySec meetup on March 11th, 2025! Again, we will have awesome presentations from the infosec / cybersecurity industry! Some snacks and beverages will be provided, hopefully! :)

Event will be held at Seinäjoki school of applied sciences, Frami F building, room F110, Seinäjoki. Specific location/room will be announced later. The speakers and timetable will also be disclosed soon-ish.

17:30 - Doors open
18:00 - Juho Lappalainen - Reframing offensive security tooling development
18:45 - Mika Lindberg - Business Email Compromise – Views from the Small Business
19:30 - Tuuli Siiskonen - Liar, Liar - Detecting Stuxnet-like data integrity attacks

Presentation info:
Reframing offensive security tooling development:
Offensive security tooling isn’t some mysterious dark art -- it’s just software development with a different perspective. This talk examines how offensive security tooling development aligns with traditional software engineering and discuss how hacking is fundamentally about creativity and thinking outside the box. Common offensive security terminology, such as C2 and implants, will be compared to their conventional software counterparts, providing a clear perspective on their similarities. The discussion will also discuss personal projects in offensive security tooling, focusing on technical challenges and lessons learned in the process.

Liar, Liar - Detecting Stuxnet-like data integrity attacks:
This work suggests and tests a solution for detecting loss of integrity with means of prediction in distributed, low-power computing environment or when collecting relational data disconnected from original data source to data ecosystems. With graph convolution network and variational auto-encoder, the proposed solution is able to detect data integrity attacks based on link prediction for datasets from various data sources without common data model. The solution has in-built mechanism to prevent poisoning the detection capability, and it is resource efficient since it does not require extensive storage capability. Due to its programmatic nature and high ability to integrate, unsupervised learning-based solution fits well in embedded system ecosystems' control functions where automated decisions are taken.
