... on the selected tokens. Evaluated on a cleaned public benchmark (PublicAMD) and a new AndroZoo-derived dataset (AndroAMD), Loom reaches F1 =0.97 on both, outperforming all string-, image-, graph-, and transformer-based baselines.

also remains robust under obfuscation (F1 above 0.90 for 7/8 Obfuscapk operators where baselines drop sharply) and temporal concept drift (F1 of 0.99 on 2022 and 0.95 on 2023 apps).

I am very happy to receive Nordea's Scientific Prize 2026! It is the result of many research and teaching collaborations, and especially of the hard-working group members I have the pleasure of working with. Many thanks to all of you and have a great summer ;-) !

My article on hidden messages within GPS signals was featured on @404mediaco. 404media.co/the-u-s-military…

The U.S. Military Quietly Turned GPS Into a Global ‘Numbers Station,’ Evidence Suggests

A random sequence in an innocuous GPS message field is likely encrypted traffic from the U.S. military's system for remotely updating cryptographic keys around the world.

Another interesting aspect that was mentioned is the homogeneity of software used at universities such as software handling emails. If a vulnerability (technical or legal) is found and exploited it could expose data for all institutions relying on this software.
