Static Analysis Targets
| Target | Search Pattern | Risk |
|---|---|---|
| Hardcoded credentials | password, secret, apikey in strings |
Critical |
| Connection strings | jdbc:, Server=, mongodb:// |
Critical |
| SQL queries | SELECT, INSERT, UPDATE |
Medium |
| URLs and endpoints | http://, https:// |
Info |
| Disabled SSL validation | ServerCertificateValidationCallback |
High |
DLL Hijacking Detection
| Step | Tool | Action |
|---|---|---|
| 1 | Procmon | Filter: Result = NAME NOT FOUND, Path ends with .dll |
| 2 | Check | Verify if DLL search path includes writable directories |
| 3 | Validate | Test with benign DLL in writable directory |
Local Storage Locations
| Location | Type | Risk |
|---|---|---|
%APPDATA%\<app> |
Config, SQLite | Credential storage |
%LOCALAPPDATA%\<app> |
Cache, logs | Data leakage |
HKCU\Software\<app> |
Registry settings | Stored credentials |
| App install directory | Config files | Hardcoded secrets |
Python Libraries
| Library | Version | Purpose |
|---|---|---|
sqlite3 |
stdlib | Audit local SQLite databases |
re |
stdlib | Pattern matching for credentials/URLs |
subprocess |
stdlib | Execute system analysis tools |
