urlscan.io offers a complimentary service for scanning and examining websites. When a user submits a URL to urlscan.io, the platform simulates a typical user's browsing experience, meticulously logging all activities generated during the navigation of that page. This encompasses the domains and IP addresses that are contacted, the types of resources requested—such as JavaScript and CSS—as well as various details regarding the page itself. Additionally, urlscan.io captures a screenshot of the website, records the DOM structure, tracks JavaScript global variables, notes any cookies established by the page, and documents a wide array of other observations. If the analyzed website is found to be targeting the users of one of the over 900 brands monitored by urlscan.io, it will be flagged as potentially harmful in the results. The aim of urlscan.io is to empower users to analyze unfamiliar and possibly dangerous websites with ease and assurance. In essence, urlscan.io serves as a valuable tool similar to a malware sandbox, enabling the analysis of suspicious URLs just as one would with dubious files. By providing these insights, urlscan.io enhances online safety and helps users make informed decisions while browsing.

Hacker AI is an innovative system designed to analyze source code for potential security flaws that could be targeted by hackers or other malicious entities. By pinpointing these vulnerabilities, businesses can implement solutions to mitigate risks and enhance their security posture. Developed by a company in Toulouse, France, Hacker AI utilizes a GPT-3 model for its analysis. To proceed, please compress your project source files into a single Zip archive and upload it; you will receive a vulnerability detection report via email within ten minutes. Currently in its beta stage, the effectiveness of Hacker AI’s findings is limited without the expertise of a cybersecurity professional experienced in code analysis. Rest assured, we do not sell or exploit your source code for harmful intentions; it is solely employed for vulnerability detection purposes. Additionally, if needed, you may request a dedicated non-disclosure agreement (NDA) from us, as well as the option for a private instance tailored to your requirements. This ensures that your sensitive information remains confidential throughout the process.
