WireTap: Breaking Server SGX via DRAM Bus Interposition

Whitepaper that delves into Intel’s Software Guard eXtension SGX. A common misconception is that physical attacks on SGX require expensive laboratory equipment, thus putting them out of reach of hobbyist-level attackers. In this work, the authors challenge this belief, showing how simple memory b...

New WireTap Attack Extracts Intel SGX ECDSA Key via DDR4 Memory-Bus Interposer

In yet another piece of research, academics from Georgia Institute of Technology and Purdue University have demonstrated that the security guarantees offered by Intel's Software Guard eXtensions SGX can be bypassed on DDR4 systems to passively decrypt sensitive data. SGX is designed as a hardware...

PYSEC-2022-184

Keylime does not enforce that the agent registrar data is the same when the tenant uses it for validation of the EK and identity quote and the verifier for validating the integrity quote. This allows an attacker to use one AK, EK pair from a real TPM to pass EK validation and give the verifier an...

Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments TEE. Called SGAxe, the first of the flaws is an evolution of the previously uncovered CacheOut attack...

Speculation Attack Against Intel's SGX

Another speculative-execution attack against Intel's SGX. At a high level, SGX is a new feature in modern Intel CPUs which allows computers to protect users' data even if the entire system falls under the attacker's control. While it was previously believed that SGX is resilient to speculative...
