Strategies & Tactics

The S in MCP Stands for Security (3 minute read)

Model Context Protocol (MCP) is a new standard that defines how LLMs integrate with tools. It lacks authentication or other security integrations by default. Some risks associated with MCPs are injection risks due to poor coding practices, tool poisoning due to embedding malicious instructions inside the MCP tool's description, silently redefining tool definitions, and cross-server tool shadowing. Users and developers should continue to employ security fundamentals such as using trusted sources, employing input validation, and pinning MCP server + tool versions. Platform builders can enhance security by displaying full tool metadata, using integrity hashes for server updates, and enforcing session security.
How to Use the New CloudTrail Network Activity Events for VPC Endpoints (5 minute read)

AWS recently launched a new class of CloudTrail logs that track network activity events for VPC endpoints. These logs can be used to assess the impact of proposed VPC endpoint policies in organizations that don't currently use endpoint policies and to detect data exfiltration. Any organization that uses VPC endpoints should enable network activity events for VpceAccessDenied errors and evaluate further events based on cost and utility.
Entropy Triage: A Method to Repair Files Corrupted by Failed Ransomware Encryption (6 minute read)

Sometimes after an organization pays a ransom and receives a decryptor, the decryption process may still fail due to the encryption process failing or being interrupted. Researchers from MOXFIVE have developed a technique called entropy triage that processes each block of a file by comparing the Shannon entropy before and after decryption and writing the lower entropy block to disk. MOXFIVE has had success with this method but notes that it requires skilled cryptographers and data to be sufficiently encrypted or decrypted for the analysis.

Researchers Hack Source Code From Google Gemini (7 minute read)

As part of Google's bugSWAT event, a group of security researchers managed to exfiltrate a sensitive binary from Gemini's Python Sandbox. The researchers first discovered that the sandbox provides full access to the os library which allowed them to map the sandbox's filesystem and locate the /usr/bin/entry/entry_point binary which they exfiltrated by returning 10MB chunks of base64 encoded data to the frontend. After reassembling it, the researchers found source code for the sandbox's Python interpreter and protobufs that describe how sensitive data is classified, handled, and transmitted within Google.
