Exploit timing windows in financial transactions

Bug bounty race condition testing on registration, payments, and single-use tokens

• · target_endpoint (fund transfer, coupon redeem, vote)
• · request (HTTP)

• · race_condition_proof (concurrent response, state manipulation)
• · impact_assessment

• · Burp Suite Turbo Intruder
• · HTTP proxy
• · Last-Byte sync technique

HTTP proxy available, Burp Suite or threading tool, target accepts parallel requests

• · Request throttling blocks concurrent sends
• · Race window too small to exploit
• · False positives from slow latency
• · Rate limiting blocks fuzzing

• · TOCTOU methodology documented
• · CL.TE/TE.CL analogs for race conditions
• · Example payloads for fund transfers
