Dida365

Security checks for vulnerabilities and agentic risk

Overview

The Dida365 actions have clear approval rules, but setup directs the agent to run unverified downloaded code without separate installation approval.

Review and approve CLI installation separately, preferably using a verified, pinned release. OOMOL will handle your connected Dida365 account. Review the CLI's automatic skill synchronization before use; its documented OO_SKILLS_SYNC_DISABLED setting can disable those writes. Installer contents and remote connector behavior were not verified. Continue requiring approval for exact account changes and deletion targets.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding

The supplied chunk performs remote installer execution rather than any visible Dida365 operation. Installation can be a supporting implementation detail, but this chunk provides no evidence connecting the Oomol installer to the declared Dida365 functionality. The downloaded script's contents and downstream effects are not available for assessment.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash command immediately executes mutable remote content without pinning a version or independently verifying its integrity; the PowerShell alternative has the same issue. HTTPS protects transport but does not protect against a compromised distribution endpoint, which could deliver code that accesses local files or alters the host under the invoking user's privileges.

First-time setup executes remote installer scripts without a system-impact warning.

Medium
Category
Output Handling
Confidence
91% confidence
Finding

The fallback setup directs the agent to execute a remote installer without explaining its host-system effects or requiring approval for installation. Although limited to a missing dependency, this can turn an ordinary Dida365 request into execution of downloaded code with the user's privileges, outside the confirmation rules for Dida365 writes.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
