A group of academics from the North Carolina State University and Dokuz Eylul University have demonstrated what they say is the "first side-channel attack" on homomorphic encryption that could be exploited to leak data as the encryption process is underway. "Basically, by monitoring power consumption in a device that is encoding data for homomorphic encryption, we are able to … [Read more...] about Researchers Demonstrate New Side-Channel Attack on Homomorphic Encryption

Researchers Demonstrate New Fingerprinting Attack on Tor Encrypted Traffic
A new analysis of website fingerprinting (WF) attacks aimed at the Tor web browser has revealed that it's possible for an adversary to glean a website frequented by a victim, but only in scenarios where the threat actor is interested in a specific subset of the websites visited by users. "While attacks can exceed 95% accuracy when monitoring a small set of five popular … [Read more...] about Researchers Demonstrate New Fingerprinting Attack on Tor Encrypted Traffic
Researchers Demonstrate 2 New Hacks to Modify Certified PDF Documents
Cybersecurity researchers have disclosed two new attack techniques on certified PDF documents that could potentially enable an attacker to alter a document's visible content by displaying malicious content over the certified content without invalidating its signature. "The attack idea exploits the flexibility of PDF certification, which allows signing or adding annotations to … [Read more...] about Researchers Demonstrate 2 New Hacks to Modify Certified PDF Documents
