the Dark Web sites, data of 617 million accounts were discovered, which were stolen from…
At the same time, almost all dark web sites use CAPTCHAs of their own design, which makes it almost impossible to develop a tool that could solve most of them.
The new tool, called DW-GAN, is different from other solutions that scientists have created in the past, usually based on a generative adversarial approach. So, the new tool is able to distinguish between letters and numbers, viewing them one by one, as well as remove “noise” from the image, defining the boundaries between letters and segmenting the contents of the picture into individual characters.
At the same time, it uses samples extracted from several local areas for character recognition (to determine fine details such as lines and edges), so it cannot be fooled by character rotation, font size change, or color mixing.
As a result, it turns out that the length of the CAPTCHA has almost no effect on the effectiveness of the new development, especially when measuring the average performance over three attempts.
DW-GAN researchers tested the already closed Yellow Brick marketplace on the dark web. The tests allowed the group to collect data on 1,831 illegal products from Yellow Brick. Among them were 286 cybersecurity-related listings (including 102 listings for stolen credit cards and 131 listings for hijacked accounts), 9 listings for fake document scans, 44 hacking tools, and 1,223 drug-related products.
In general, the framework under consideration is capable of automatically cracking CAPTCHAs in no more than three attempts. Hacking all CAPTCHA images took a total of about 76 minutes for all 1,831 ads, and the process was fully automated.the report says.
Let me remind you that we wrote that Cloudflare aims to save the world of CAPTCHAs. You might also be interested to know that Attackers use voice changing software to deceive their victims.
