Captcha Recognition Technology Evolution: New Trends in AI Cracking

When CAPTCHA Meets AI: An Upgraded Game of Cat and Mouse

Ten years ago, the site hung a four-digit CAPTCHA will be able to prevent robots, and now this set of tricks have long been ineffective. Crawler friends should understand, now encountered point to select the hot pot picture of the CAPTCHA, the blood pressure can directly soar to 180. However, recently a new way to play began to popularize - with the proxy IP pool to raise AI models, this set of combined punches out, the CAPTCHA system's defenses with the same as the paper mache.

CAPTCHA Hacking Triple Axe

The mainstream crack path is now divided into three main steps:Get data, train models, raise IP. The first two links technology geeks play thieves, but the third link is often overturned. Many teams spend a lot of money to train the model, the actual combat by the target site blocked IP blocked to doubt life.

IP pools are the key to victory

I've seen too many cases where the technical team's algorithm was written in a flying manner, but the result was planted on the IP resources. A good IP pool has to meet three conditions:Large quantity, stable quality, fast switching. Take our own ipipgo's service for example, global 30 million + residential IP resources, each IP with a maximum of 5 minutes to automatically switch, with intelligent routing algorithms, can perfectly simulate the different regions of the real user Internet behavior.

The advantages of residential agents are highlighted here:
- Direct carrier-provided home broadband IP
- Will not be flagged as data center traffic
- Support for specific city-level positioning
- Success rate of requests generally above 95%

A guide to avoiding pitfalls in the real world

Recently helped an e-commerce client to do price monitoring, they engage in their own time was blocked more than 300 IP every day. changed to use ipipgo's dynamic residential proxy, three key improvements:
1. Randomized delay added to the request interval (0.5-3 seconds)
2. Randomization of UA and time zone per request
3. Allocate IPs according to the location of the target web server.
This set of combinations of punches down, data collection efficiency directly doubled 8 times, the most critical is running for three consecutive months did not trigger the CAPTCHA system.

question-and-answer session

Q: Is it legal to collect data with a proxy IP?
A: This matter depends on the specific use of the scene and the agreement of the target site, ipipgo strictly require customers to comply with the laws and regulations of various places, it is recommended to use within the scope of authorization.

Q: How do I choose between a residential agent and a server room agent?
A: To pass the CAPTCHA preferred residential agent, ordinary data collection with the machine room agent more cost-effective. ipipgo two types are available, but also can be mixed and matched use.

Q: What should I do if I encounter a particularly perverse CAPTCHA?
A: It is recommended on the human verification solutions, ipipgo API support seamlessly with mainstream CAPTCHA recognition services, encountered Google's reCAPTCHA can also be dealt with.

The new shape of the future battlefield

Now the CAPTCHA system began to play the behavioral analysis of this set, not only to see what you enter, but also staring at how you move the mouse, how to slide the screen. At this time, the quality of the proxy IP directly determines the life and death of the poor-quality IP features are too obvious, minutes by the system marking. Recently, we have started to integrate the browser fingerprint simulation technology into our customer's solution, together with ipipgo's accurate positioning of the proxy, to disguise the machine's behavior more real than the real person.

In the final analysis, the attack and defense war is the thickness of resources and technology iteration speed. If you want to survive the long battle of CAPTCHA cracking.A reliable proxy IP service is your ammo bank!. If you are interested, you can try ipipgo's free trial package, which gives new users 5G of traffic experience, enough for you to test various CAPTCHA scenarios.
