Algorand Vulnerability Scanner
1. Purpose
Systematically scan Algorand smart contracts (TEAL and PyTeal) for platform-specific security vulnerabilities documented in Trail of Bits' "Not So Smart Contracts" database. This skill encodes 11 critical vulnerability patterns unique to Algorand's transaction model.
2. When to Use This Skill
- Auditing Algorand smart contracts (stateful applications or smart signatures)
- Reviewing TEAL assembly or PyTeal code
- Pre-audit security assessment of Algorand projects
- Validating fixes for reported Algorand vulnerabilities
- Training team on Algorand-specific security patterns
3. Platform Detection
File Extensions & Indicators
- TEAL files:
.teal - PyTeal files:
.pywith PyTeal imports
Language/Framework Markers
# PyTeal indicators
from pyteal import *
from algosdk import *
# Common patterns
Txn, Gtxn, Global, InnerTxnBuilder
OnComplete, ApplicationCall, TxnType
@router.method, @Subroutine
Project Structure
approval_program.py/clear_program.pycontract.teal/signature.teal- References to Algorand SDK or Beaker framework
Tool Support
- Tealer: Trail of Bits static analyzer for Algorand
- Installation:
uv tool install tealer(ensure uv's tool bin dir is on PATH) - Usage:
tealer contract.teal --detect all
4. How This Skill Works
When invoked, I will:
- Search your codebase for TEAL/PyTeal files
- Analyze each file for the 11 vulnerability patterns
- Report findings with file references and severity
- Provide fixes for each identified issue
- Run Tealer (if installed) for automated detection
5. Example Output
When vulnerabilities are found, you'll get a report like this:
=== ALGORAND VULNERABILITY SCAN RESULTS ===
Project: my-algorand-dapp
Files Scanned: 3 (.teal, .py)
Vulnerabilities Found: 2
---
[CRITICAL] Rekeying Attack
File: contracts/approval.py:45
Pattern: Missing RekeyTo validation
Code:
If(Txn.type_enum() == TxnType.Payment,
Seq([
# Missing: Assert(Txn.rekey_to() == Global.zero_address())
App.globalPut(Bytes("balance"), balance + Txn.amount()),
Approve()
])
)
Issue: The contract doesn't validate the RekeyTo field, allowing attackers
to change account authorization and bypass restrictions.
6. Vulnerability Patterns (11 Patterns)
I check for 11 critical vulnerability patterns unique to Algorand. For detailed detection patterns, code examples, mitigations, and testing strategies, see VULNERABILITY_PATTERNS.md.
Pattern Summary:
- Rekeying Vulnerability ⚠️ CRITICAL - Unchecked RekeyTo field
- Missing Transaction Verification ⚠️ CRITICAL - No GroupSize/GroupIndex checks
- Group Transaction Manipulation ⚠️ HIGH - Unsafe group transaction handling
- Asset Clawback Risk ⚠️ HIGH - Missing clawback address checks
- Application State Manipulation ⚠️ MEDIUM - Unsafe global/local state updates
- Asset Opt-In Missing ⚠️ HIGH - No asset opt-in validation
- Minimum Balance Violation ⚠️ MEDIUM - Account below minimum balance
- Close Remainder To Check ⚠️ HIGH - Unchecked CloseRemainderTo field
- Application Clear State ⚠️ MEDIUM - Unsafe clear state program
- Atomic Transaction Ordering ⚠️ HIGH - Assuming transaction order
- Logic Signature Reuse ⚠️ HIGH - Logic sigs without uniqueness constraints
For complete vulnerability patterns with code examples, see VULNERABILITY_PATTERNS.md.
7. Scanning Workflow
Step 1: Platform Identification
- Confirm file extensions (
.teal,.py) - Identify framework (PyTeal, Beaker, pure TEAL)
- Determine contract type (stateful application vs smart signature)
- Locate approval and clear state programs
Step 2: Static Analysis with Tealer
# Run Tealer on contract
tealer contract.teal --detect all
# Or specific detectors
tealer contract.teal --detect unprotected-rekey,group-size-check,update-application-check
Step 3: Manual Vulnerability Sweep
For each of the 11 vulnerabilities above:
- Search for relevant transaction field usage
- Verify validation logic exists
- Check for bypass conditions
- Validate inner transaction handling
Step 4: Transaction Field Validation Matrix
Create checklist for all transaction types used:
Payment Transactions:
- RekeyTo validated
- CloseRemainderTo validated
- Fee validated (if smart signature)
Asset Transfers:
- Asset ID validated
- AssetCloseTo validated
- RekeyTo validated
Application Calls:
- OnComplete validated
- Access controls enforced
- Group size validated
Inner Transactions:
- Fee explicitly set to 0
- RekeyTo not user-controlled (Teal v6+)
- All fields validated
Step 5: Group Transaction Analysis
For atomic transaction groups:
- Validate
Global.group_size()checks - Review absolute vs relative indexing
- Check for replay protection (Lease field)
- Verify OnComplete fields for ApplicationCalls in group
Step 6: Access Control Review
- Creator/admin privileges properly enforced
- Update/delete operations protected
- Sensitive functions have authorization checks
8. Reporting Format
Finding Template
## [SEVERITY] Vulnerability Name (e.g., Missing RekeyTo Validation)
**Location**: `contract.teal:45-50` or `approval_program.py:withdraw()`
**Description**:
The contract approves payment transactions without validating the RekeyTo field, allowing an attacker to rekey the account and bypass future authorization checks.
**Vulnerable Code**:
```python
# approval_program.py, line 45
If(Txn.type_enum() == TxnType.Payment,
Approve() # Missing RekeyTo check
)
```
**Attack Scenario**:
1. Attacker submits payment transaction with RekeyTo set to attacker's address
2. Contract approves transaction without checking RekeyTo
3. Account authorization is rekeyed to attacker
4. Attacker gains full control of account
**Recommendation**:
Add explicit validation of the RekeyTo field:
```python
If(And(
Txn.type_enum() == TxnType.Payment,
Txn.rekey_to() == Global.zero_address()
), Approve(), Reject())
```
**References**:
- building-secure-contracts/not-so-smart-contracts/algorand/rekeying
- Tealer detector: `unprotected-rekey`
9. Priority Guidelines
Critical (Immediate Fix Required)
- Rekeying attacks
- CloseRemainderTo / AssetCloseTo issues
- Access control bypasses
High (Fix Before Deployment)
- Unchecked transaction fees
- Asset ID validation issues
- Group size validation
- Clear state transaction checks
Medium (Address in Audit)
- Inner transaction fee issues
- Time-based replay attacks
- DoS via asset opt-in
10. Testing Recommendations
Unit Tests Required
- Test each vulnerability scenario with PoC exploit
- Verify fixes prevent exploitation
- Test edge cases (group size = 0, empty addresses, etc.)
Tealer Integration
# Add to CI/CD pipeline
tealer approval.teal --detect all --json > tealer-report.json
# Fail build on critical findings
tealer approval.teal --detect all --fail-on critical,high
Scenario Testing
- Submit transactions with all critical fields manipulated
- Test atomic groups with unexpected sizes
- Attempt access control bypasses
- Verify inner transaction fee handling
