Full Report
There has been a fair bit of blog buzz about the new SQL Injection worm that ran around infecting sites. I have not looked too deeply into it, but have not yet seen accounts of how the targeting was done. Since the sites do not appear to have been running a common framework i would guess that it was search-engine generated targets based on resource name (like inurl: search.asp).. For ages we have been telling people that if they had to have a /admin/admin.asp on their internet facing web-app that they would at least help minimize their exposure a little by naming it /admin_[bet_u_dont_find_this]/admin_[another_variable].asp
Analysis Summary
# Tool/Technique: SQL Injection Worm (Targeting via URL/Resource Name)
## Overview
This summarization focuses on a "new SQL Injection worm" observed in the wild, specifically noting the mechanism it likely used for target discovery—based on predictable or common resource names within URLs, rather than traditional vulnerability scanning against common frameworks.
## Technical Details
- Type: Technique/Automated Exploitation (Worm behavior implied)
- Platform: Web Applications utilizing ASP (implied by examples like `search.asp`, `admin.asp`, `login.asp`)
- Capabilities: Exploitation of SQL Injection vulnerabilities across numerous web targets discovered via search queries.
- First Seen: Prior to January 10, 2008 (date of article publication).
## MITRE ATT&CK Mapping
This behavior primarily relates to initial access and reconnaissance focused on widespread discovery.
- **TA0001 - Initial Access**
- **T1190 - Exploit Public-Facing Application**
- *While direct exploitation details are missing, the worm's behavior implies automated exploitation of discovered vulnerabilities.*
- **TA0043 - Reconnaissance**
- **T1598 - Phishing for Information** (Analogous if search engines are treated as a target information source)
- **T1598.003 - Search Engine** (The suspected targeting method relies on leveraging search engine results matching specific resource names.)
## Functionality
### Core Capabilities
- **Target Discovery**: Identifying vulnerable web applications by querying search engines (e.g., using queries like `inurl:search.asp` or `inurl:login.asp`) to find exposed resource paths that suggest the presence of a web application endpoint.
- **Automated Exploitation**: The activity is described as a "worm," implying automated scanning and exploitation attempts against all discovered targets using SQL Injection payloads.
### Advanced Features
- The text suggests the worm operates by pattern matching on URLs/resource names (e.g., searching for specific file names like `admin.asp` or `login.asp`), treating the resulting URLs as potential victims, analogous to how attackers might use non-standard ports to hide services.
## Indicators of Compromise
*Note: No specific IOCs are provided in the text, as the article focuses on the targeting technique.*
- File Hashes: N/A
- File Names: N/A
- Registry Keys: N/A
- Network Indicators: N/A
- Behavioral Indicators: Mass scanning/probing of web applications leveraging specific filename patterns in the path structure.
## Associated Threat Actors
- Undisclosed actors responsible for deploying the SQL Injection worm discussed.
## Detection Methods
*Detection methods are largely preventative based on the observed technique.*
- Signature-based detection: Likely ineffective against novel, rapid deployment/worm activities unless payloads are already known.
- Behavioral detection: Monitoring for high volumes of requests to web paths containing common administrative or login filenames (`.asp`, `.php`, etc.).
- YARA rules: N/A
## Mitigation Strategies
The article heavily emphasizes hardening defense mechanisms to avoid detection via this targeting method:
- **Prevention**: Avoid using trivial, easily guessable names for critical administrative or exposed resources (e.g., rename `/admin/admin.asp`).
- **Hardening Recommendations**: Rename resource paths to unique, non-obvious names (e.g., `/admin_[bet_u_dont_find_this]/admin_[another_variable].asp`). This is a form of security through obscurity suggested as a "speed bump."
- **General SQLi Prevention**: Apply standard defenses against SQL Injection (parameterized queries, input validation).
## Related Tools/Techniques
- Automated Web Vulnerability Scanning Tools (which might use similar search string logic for reconnaissance).
- Generic SQL Injection Payloads used for mass exploitation.
- Port scanning (analogized as a method to hide services, contrasting with the worm's method of hiding behind common filenames).
