New research alert 🚨 from my group, “Blockchain Address Poisoning” (Tsuchiya et al.), to appear at USENIX Security 2025 (arxiv.org/abs/2501.16681)! As a follow-up, we also developed a real-time detection system: cryptotrade.cylab.cmu.edu/poisoning/ and x.com/toxin_tagger (1/7)

Just because your prof didn't file an academic dishonesty report does not mean that they don't know you cheated. Knowing you did it and proving it to the hearing board are two different thresholds.

Pasta sauce cookie is something you should only attempt after you’ve gotten your second Michelin star. Like, David Chang, I’d eat his pasta sauce cookie no questions. Doing it myself because the teevee told me to, yeah, no.

They just ran a commercial for Google AI where a guy was making pasta sauce and poured too much sugar in, and the AI suggested he turn it into cookies (?). Then he ate one and was like “mmm!” What the actual fuck is wrong with this whole planet man

If you're a grad student or an undergrad interested in research I need to you listen to me very carefully. You cannot learn to write good research papers if you do not read good research papers. Stop asking LLMs to summarize papers for you.

I'm thrilled to announce that I'll be joining Carnegie Mellon as an Assistant Professor of Human-Computer Interaction (with a courtesy joint appointment in Social and Decision Sciences) in 2026!

In a @darkreading.bsky.social article, Professor Lorrie Cranor (@lorriecranor.bsky.social), CyLab Director, explains to Becky Bracken (@beckybracken.bsky.social) why, regardless of #encryption protections, #Gmail user devices and accounts still need to be secured.

Gmail Is Not a Secure Way to Send Sensitive Comms

New end-to-end Gmail encryption alone isn't secure enough for an enterprise's most sensitive and prized data, experts say.
