[ACM CCS 2025] Want to host a workshop at CCS 2025? Check out the "Call for Workshops" here. 😃 Deadline March 14 (AoE) @acm_ccs sigsac.org/ccs/CCS2025/call-…

We worked with colleagues from Futurum Careers (@FUTURUMCareers) to develop an article about our deepfake and phishing research and an activity sheet for K-12. @IllinoisCS - Article: futurumcareers.com/can-you-t… - Activity sheet: futurumcareers.com/Gang-Wang…

We are organizing a KDD workshop on AI-enabled Cybersecurity Analytics and Deployable Defense (AI4Cyber/MLHat). ai4cyber-kdd.com/ Please consider submitting a paper. We will meet in person in DC this year! #CyberSecurity #MachineLearning #DataScience #infosec @kdd_news

... and are widely used for reverse image search for cybercrime analysis (e.g., detecting catfish profiles, misinformation). In this paper, we analyze its robustness and present a series of attacks to subvert perceptual hashing based image search.

(1/n) Virtually attending CCS (@acm_ccs) this week! Qingying (qingyinghao.web.illinois.edu…) presented her first-ever CCS paper: "It’s Not What It Looks Like: Manipulating Perceptual Hashing based Applications." Perceptual hashing algorithms generate "fingerprints" for images ...

Moving forward, PoP assignments can be improved by different DoH providers.

Certain countries suffer significantly longer delays when switching from standard DNS to DoH. Statistical analysis shows it disproportionately impacts countries with lower income and less Internet infrastructure investment.

This is joint work with @_kumarde, @paul_murley, and Michael Bailey. Some selected findings: 1) More Points of Presence (PoP) do not always mean better performance:

@ACM_IMC2021 is happening now! #IMC2021.  Rishabh Chhabra (@rc1288) will present our measurement study on DNS-over-HTTPS (DoH) Performance around the world, to understand how DoH rollout would (unevenly) impact different regions (20K clients, 200+ countries).

Steve is presenting our talk today in ⁦@IEEESSP⁩ “Throwing Darts in the Dark: Detecting Bots with Limited Data using Neural Data Augmentation” youtube.com/watch?v=oW0tMLzq…

Super proud of my first Ph.D. student Hang Hu, who passed his dissertation defense today! Hang has worked on various projects focusing on online deception and privacy threats (people.cs.vt.edu/hanghu). He will be joining Google after graduation (1/3)
