But with reCAPTCHA v2, the response/ʜᴛᴛᴘ header sent to the server looks like this: g-recaptcha-response:03AJpayVEtSKNOXg7TJwMkmxzLA_HrnWMKm6p0o圆W6hhMcw3Bzxab8ariLgg8Q8wXpUcF8HLkhAd1ixXgNvBDde5ggVXidl3NuHSQcnP4QqJkVvWZ2s4_CQ1lHTw6oNEqXyiBuS3CkiHBhoB5akijJ6ld115K_OWZo6mfB4xz_-I2P36fVqT9VzEUz26wrauN9QZuC6lh80mf-fkxqCPmNYSOcMrHxR33Flby05gzo5cD1B-2FucaoFP11p2svvZrWC_vAjz5bGOzW0DufM2kkdtLIlhzl9GBzm_chyirSJItHGdz0bMuxDYZkRKY8c4gXUmzT09VEgivi032zZnNXtrVA04gXF5yE0tAtnGTwi31hMdzumPoc6GdLdIbvfbXgdyndocCLIph-j9T8ePf3JO8Jfcf6BNcmUKT2SrhZjIAPUOZV2Mg7Qua_s4zNHYx1-NE8zoe9SG-VxuPbx2sjR32ce4oapa6VAĮven with an audio to text sample. Most of the time, the explanation is neural networks services provided by Google or IBM.īut there is something I am failing to understand: for most CAPTCHA(including reCAPTCHA v1) the manually deciphered text is sent directly to the server inside an ʜᴛᴛᴘ header. There are multiple reports of a reᴄᴀᴘᴛᴄʜᴀ v2 bypass.
