CAPTCHA Hacking Tool: Automatic Recognition Solution

Teach you to use a proxy IP to get the CAPTCHA!

Brothers engaged in automation understand that the CAPTCHA is a roadblock. Especially with the script batch operation, the site found that the same IP frequent requests, light pop-up CAPTCHA, heavy direct seal. This time we have to rely on proxy IP toDiversification of riskIt's like fighting a guerrilla war where you have to keep changing positions.

Why Proxy IPs are CAPTCHA Busters?

To give a real case: an e-commerce friends to batch check logistics, with their own broadband to run scripts, the results of the next day the entire company's network were the target site black. Later changed ipipgo's dynamic residential agent, every check 5 times on the IP change, continuous running for half a month are no problem.

 Python example: accessing a target website with rotating IPs
import requests
from itertools import cycle

 Proxy IP pool from ipipgo
proxies = [
    "http://user:pass@gateway.ipipgo.com:2000",
    "http://user:pass@gateway.ipipgo.com:2001",
    "http://user:pass@gateway.ipipgo.com:2002"
]

proxy_pool = cycle(proxies)

for _ in range(10).
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        resp = requests.get("target url",
            proxies={"http": current_proxy},
            timeout=10
        )
         Here is the CAPTCHA code...
    except: print(f "http": current_proxy}, timeout=10 )
        print(f"{current_proxy} failed, automatically switching to the next one.")

The Three Fateful Things About Choosing a Proxy IP

Agent service providers on the market are a mixed bag, these three indicators must be dead on:

① Real-life behavioral simulation:ipipgo's residential proxies come with a real user network environment and are harder to recognize than server room IPs
② Speed of response:The average response is <0.8 seconds, which is much more reliable than some of the ones that take 3 seconds.
③ Failure to retry mechanism:It is recommended to set up 3 times auto switching with ipipgo's 99% availability to carry the load

A Guide to Avoiding the Pit (Lessons Learned Through Tears)

Stepped on a mine last year while helping a client with their ticketing system:

• Free proxies don't work at all. 8 out of 10 don't work.
• Overseas IP access to domestic websites instead of triggering verification
• Short-lived proxies should be coupled with IP survival detection (ipipgo has real-time monitoring in the background)

QA time

Q: Proxy IP + CAPTCHA recognition is enough for 100% to succeed?
A: Wake up! Site defense is also upgrading, the recommended combination: ipipgo proxy + request frequency control + simulate the mouse track

Q: Why do you recommend ipipgo?
A: Comparative data from actual measurements of own projects:

Q: What should I do if I encounter a sliding captcha?
A: Don't be rigid! Use a proxy IP dispersed to different devices to deal with, or connected to a professional coding platform, after all, some money can not be saved!

Tell the truth.

There is no once-and-for-all solution in this business, just last week I saw a peer with a poor quality proxy, the result is that the customer account all get blocked. It is recommended that important projects directly on the ipipgo enterprise edition, with theAutomatic Route Optimizationrespond in singingIP Quality ScoreIt's a lot more fun than tossing yourself. After all, time is money, have this effort is not as good as two hours of sleep.
