This tweet mentions a WAF bypass challenge involving the word "resolved_model". The user says some WAF blocks this specific word, preventing deeper exploration or exploitation. They also tried using unicode encoding for bypass but it didn't work. This indicates that some WAFs have specific keyword or signature-based filtering that blocks certain sensitive words which could be part of attack vectors. However, standard unicode obfuscation is not effective for bypassing this particular block. Therefore, bypassing such restrictive filters may require alternative encoding, obfuscation techniques, or payload variants rather than just relying on unicode encoding. The tweet is about recognizing keyword-based WAF filtering and the difficulty of bypassing it with simple obfuscation methods.
