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: .py with 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.py
contract.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
