“Super Malware” Steals Encryption Keys From Intel SGX Isolated Memory Fields

A scientist’s Team from Graz University of Technology revealed the method that leaking the  encryption data from Intel SGX (Software Guard Extensions ) enclaves which is called Isolated Memory FIeld .

Intel SGX is a set of new instructions from Intel that allows user-level code to allocate private regions of memory, called enclaves, that unlike normal process memory is also protected from processes running at higher privilege levels.

Security Research Team develop this”super Malware” under PoC (Proof of Concepts) and they Explained in their Research Paper , how this “Super Malware” leak the data from Isolated memory field by cache attack .

Also explained about the Attack Vector ,

Our proof-of-concept malware is able to recover RSA keys by monitoring cache access patterns of an RSA signature process in a semi-synchronous attack,” researchers said.In a semi-synchronous attack, we extract 96% of an RSA private key from a single trace,” they said. “We extract the full RSA private key in an automated attack from 11 traces within 5 minutes.

Researcher Explained in their Research Paper,  “we show that it is very well possible for enclave malware to attack its hosting system. We demonstrate a cache attack from within a malicious enclave that is ex-tracting secret keys from co-located enclaves.”

“Our proof-of-concept malware is able to recover RSA keys by monitoring cache access patterns of an RSA signature process in a semi-module.”

This protects enclaves against hardware attacks trying to read or manipulate enclave content in DRAM.Creation and loading of enclaves are done by the oper-ating system.

“Super Malware” hide from anti-virus scanners

Researchers said ,To protect the integrity of enclave code, the loading procedure is measured by the CPU.

“If the resulting measurement does not match the value specified by the enclave developer, the CPU will refuse to run the enclave.”

During enclave loading, the operating system has full access to the enclave binary.

“At this point anti-virus scanners can hook in to analyze the enclave binary before it is executed. Enclave malware will attempt to hide from anti-virus scanners by encrypting malicious payload.”

API Vulnerability Scanning

71% of the internet traffic comes from APIs so APIs have become soft targets for hackers.Securing APIs is a simple workflow provided you find API specific vulnerabilities and protect them.In the upcoming webinar, join Vivek Gopalan, VP of Products at Indusface as he takes you through the fundamentals of API vulnerability scanning..
Key takeaways include:

  • Scan API endpoints for OWASP API Top 10 vulnerabilities
  • Perform API penetration testing for business logic vulnerabilities
  • Prioritize the most critical vulnerabilities with AcuRisQ
  • Workflow automation for this entire process
