Answer: Day 08/100

This is a classic Web Application Attack
Chain SQL Injection Web Shell Internal C2 Beaconing.

What's likely happening:

Developer pushed new code with an unparameterized SQL query. Attacker found the exposed endpoint within 30 minutes using automated scanners.

500 alerts = not human. A tool like SQLMap or Burp Suite ran this.

1. SQL Injection hit first attacker dumped credentials from the database silently while SIEM was still waking up.

2. Used dumped creds to authenticate as admin uploaded a web shell disguised as an image file (shell.php.jpg)

3. Web shell = their permanent backdoor now they live inside your server.

4. Internal server beaconing = attacker already moved. Web layer was just the entry point.

How you hunt it:

1. Pull Apache/Nginx access logs grep for ' OR 1=1--, UNION SELECT, ../../../ immediately.

2. Check HTTP 200 responses after failed logins 200 = bypass worked.

3. Sysmon Event ID 3 - what process owns that outbound connection on the internal server.

4. Hunt /var/www/uploads/ any .php files hiding inside image folders = web shell.

5. Hash every new file deployed run against VirusTotal instantly.

6. Check if same foreign IP appears across other internal machines was this server the only target.
MITRE ATT&CK Mapping:

1. T1190 - Exploit Public Facing Application - Initial Access.

2. T1505.003 - Web Shell-Persistence.

3. T1078 - Valid Accounts (dumped credentials) Privilege Escalation.

4. T1071 - Application Layer Protocol C2 over HTTP Command & Control.

5. T1059 - Command Execution via Web Shell Execution.

Real answer interviewers want:

"It was both a bug AND an attack. The developer created the vulnerability. The attacker exploited it in 30 minutes.Security must shift left catch it in code review, not in the SIEM."
