iLeakage: New Safari Exploit Impacts Apple iPhones and Macs with A- and M-Series CPUs

A group of academics has devised a novel side-channel attack dubbed iLeakage that exploits a weakness in the A- and M-series CPUs running on Apple iOS, iPadOS, and macOS devices, enabling the extraction of sensitive information from the Safari web browser. "An attacker can induce Safari to render...

Patch…later? Safari iLeakage bug not fixed

Apple has released updates for its phones, Macs, iPads, watches, and TV streaming devices, fixing a bunch of security problems. But amid all that activity, one fix is notably absent—there is nothing to address the vulnerability dubbed iLeakage. iLeakage is a side-channel attack that can force the...

Side Channel Attack

libcryptopp.so is vulnerable to Timing Attack. The vulnerability arises from non-constant time scalar multiplication in ecp.cpp prime field curves with small leakage and algebra.cpp binary field curves with large leakage. This leakage allows an attacker to measure the duration of hundreds to...

Researchers Uncover New GPU Side-Channel Vulnerability Leaking Sensitive Data

A novel side-channel attack called GPU.zip renders virtually all modern graphics processing units GPU vulnerable to information leakage. "This channel exploits an optimization that is data dependent, software transparent, and present in nearly all modern GPUs: graphical data compression," a group...
