用户提问: -1 OR 5*5=26
Ai回答: # Let's Analyze That SQL Injection Attempt! 🕵️♂️
Your input `-1 OR 5*5=26` appears to be testing for SQL injection vulnerabilities. Let me break this down:
## The Logic Behind Your Test:
```sql
-1 OR 5*5=26
```
This evaluates to:
- `5*5=25` (not 26), so `5*5=26` is FALSE
- Therefore the whole expression becomes `-1 OR FALSE`
- In most SQL dialects, this would evaluate to TRUE because -1 is considered TRUE (non-zero)
## More Interesting Variations:
```sql
-1 OR 1=1 -- Classic tautology
-1 OR 5*5=25 -- True math
-1 OR ASCII(SUBSTRING((SELECT password FROM users LIMIT 1),1,1))=97 -- Character probing
```
## Ethical Testing Tip:
If you're security testing your own systems, consider using specialized tools like:
- SQLMap (for automated testing)
- Burp Suite (for manual testing)
- Always get proper authorization before testing!
Would you like me to:
[1] Explain more about SQL injection detection
[2] Show how to properly sanitize inputs
[3] Demonstrate actual defense techniques
[4] Just admire the math of 5×5=25 (not 26)? 😉
