Tamper-Proofing with Self-Modifying Code

Classical computability theory tells us that self-modifying code SMC on a deterministic universal Turing machine can be simulated by non-SMC code on the same model. That abstraction, however, omits the external timing inputs, concurrency, and microarchitectural state that dominate practical...

Efficient Instruction Cache Attacks via Self-Modifying Code Conflicts

Bulletin ID: AMD-SB-7024 Potential Impact: N/A Severity: N/A Summary AMD is aware of a paper titled ‘SMaCK: Efficient Instruction Cache Attacks via Self-Modifying Code Conflicts,’ published by researchers from Iowa State University and Google®.

Dynamic API Call Tracer for Windows and Linux Applications: Drltrace

Drltrace is a dynamic API calls tracer for Windows and Linux applications designed primarily for malware analysis. Drltrace is built on top of DynamoRIO dynamic binary instrumentation framework. Motivation Malware analysis is not an easy task. Sophisticated software packers like Themida and...

Dan Geer: Cybersecurity, Humanity's Future "Conjoined"

Given the intertwinement of technology with communication, politics, economies and overall human progress, it seems to go hand-in-hand that cybersecurity must be elevated in parallel. Dan Geer, considered atop the food chain of security thinkers, said during last week’s Source Boston conference...

High Throughput Fuzzer: Grr

High Throughput Fuzzer GRR is an x86 to amd64 binary translator. GRR was created to emulate and fuzzer DECREE challenge binaries. GRR was created for the DARPA Cyber Grand Challenge. Features Code cache persistence avoids translation overheads across separate runs. Optimization of the code cache,...
