Full Report
Brilliant, the client has decided to implement their own CMS and you’ve found a variable that’s vulnerable to SQL injection. Starting up your favourite SQL exploitation tool, you upload a suitable web shell and fire up the browser. In an instant, you control that server, but do you really own the box? Looking back at the major hacks of the last 18 months, attackers used a variety of techniques to obtain sensitive information. For the RSA hack, social engineering was used, allegedly consisting of a malicious Excel spreadsheet sent from a web master at a recruitment website. Once loaded, Poison Ivy was dropped on the host and the games began. Attackers started recon exercises, pivoting between hosts and finally exfiltrated the data (the rest is well-known and publicised). In the case of HBGary, attackers compromised their systems using a similar approach as the RSA attackers did: target an individual using social engineering using an earlier toehold to expand to a foothold. These types of attackers might have a fancy new name (Advanced Persistent Threats) but at the end of the day, they are using techniques that have been around for a while.

## Associated Threat Actors
- General attackers utilizing web application exploitation.
## Detection Methods
- Signature-based detection: Detections based on known web shell signatures (e.g., specific PHP/ASP/JSP functions used for command execution like `system()`, `exec()`, or ASP `.asp?cmd=`).
- Behavioral detection: File integrity monitoring (FIM) alerting on new .php, .asp, or .aspx files in web roots.
- YARA rules if available: Rules targeting specific command execution functions within common web shell source code.
## Mitigation Strategies
- Prevention measures: Eliminating the initial vulnerability (SQLi, RCE, LFI).
- Hardening recommendations: Restricting web server process permissions to the absolute minimum required; implementing application allow-lists for executed functions.
