performing-ransomware-tabletop-exercise
Plans and facilitates tabletop exercises simulating ransomware incidents to test organizational readiness, decision-making, and communication procedures. Designs realistic scenarios based on current ransomware threat actors (LockBit, ALPHV/BlackCat, Cl0p), injects covering double extortion, backup destruction, and regulatory notification requirements. Evaluates participant responses against NIST CSF and CISA guidelines. Activates for requests involving ransomware tabletop, incident response exercise, or ransomware readiness drill.

-
performing-api-rate-limiting-bypass
Tests API rate limiting implementations for bypass vulnerabilities by manipulating request headers, IP addresses, HTTP methods, API versions, and encoding schemes to circumvent request throttling controls. The tester identifies rate limit headers, determines enforcement mechanisms, and attempts bypasses including X-Forwarded-For spoofing, parameter pollution, case variation, and endpoint path manipulation. Maps to OWASP API4:2023 Unrestricted Resource Consumption. Activates for requests involving rate limit bypass, API throttling evasion, brute force protection testing, or API abuse prevention assessment.
