In April, Tim Beyne and Vincent Rijmen from COSIC taught a two-day course on linear cryptanalysis for Master's students at KU Leuven. We recorded it and are now sharing the lectures with everyone: 8 videos on YouTube.

Paris prosecutor sees sufficient indications that Iran hacked the fridges and freezers of ~700 French supermarkets. Bart Preneel isn't surprised: “Those groups are, in general, quite active.”

France has blamed the cyber unit of Iran's Revolutionary Guard for the October attack that pushed the cold rooms of 700+ supermarkets to 50°C.
"Those cooling systems leaked like a sieve," says Prof. Bart Preneel in @destandaard. #cybersecurity https://t.co/ihYzNOwZKF (paywall)

Belgium faces a record wave of cyberattacks, from town halls to supermarket freezers. In @destandaard, Prof. Bart Preneel links it to powerful AI models: “Anything can be a target.” #Cybersecurity

“Last week we saw a cyberattack on Ahold Delhaize and French refrigerators; now there’s a PHP leak. It is highly likely that things like this will happen every week for the next two years.”

Post-quantum crypto must be secure not only on paper, but also in real hardware and software. That's the aim of #EQUIP, a new 3-year #HorizonEurope project in which COSIC joins @PqShield, Tampere Uni, @CryptoExperts , TU Graz and TECHNIKON. #PQC

Welcome to the new postdoc in Frederik Vercauteren's team: Simon Pohmann!
His current research is on both theoretical and implementation aspects of lattice-based cryptography, in particular Fully Homomorphic Encryption (FHE).

The #PHP flaw is patched, but not everywhere yet. Prof. Bart Preneel warns that #AI is exposing vulnerabilities much faster:
“It may well be that we’ll have something like this every week for the next two years.”
