Kraken: Higher-order EM Side-Channel Attacks on DNNs in Near and Far Field
Peter Horvath, Ilia Shumailov, Lukasz Chmielewski +2
The multi-million dollar investment required for modern machine learning (ML) has made large ML models a prime target for theft. In response, the field of model stealing has emerge…
Chypnosis: Undervolting-based Static Side-channel Attacks
Kyle Mitard, Saleh Khalaj Monfared, Fatemeh Khojasteh Dana +3
Static side-channel analysis attacks, which rely on a stopped clock to extract sensitive information, pose a growing threat to embedded systems' security. To protect against such a…
Thunderhammer: Rowhammer Bitflips via PCIe and Thunderbolt (USB-C)
Robert Dumitru, Junpeng Wan, Daniel Genkin +4
In recent years, Rowhammer has attracted significant attention from academia and industry alike. This technique, first published in 2014, flips bits in memory by repeatedly accessi…
Slice+Slice Baby: Generating Last-Level Cache Eviction Sets in the Blink of an Eye
Bradley Morgan, Gal Horowitz, Sioli O'Connell +7
An essential step for mounting cache attacks is finding eviction sets, collections of memory locations that contend on cache space. On Intel processors, one of the main challenges…
On Borrowed Time -- Preventing Static Side-Channel Analysis
Robert Dumitru, Thorben Moos, Andrew Wabnitz +1
In recent years a new class of side-channel attacks has emerged. Instead of targeting device emissions during dynamic computation, adversaries now frequently exploit the leakage or…
