Microsoft’s mission is to enhance people’s ability to discover, create, and utilize knowledge by revolutionizing the most widely used web tools, namely the search engine and browser. Recently, Microsoft announced the launch of an all-new AI-powered Bing search engine and Edge browser, which are now available for preview on Bing.com. These tools will offer improved search capabilities, complete answers, a new chat experience, and content generation, effectively serving as an AI copilot for the web.
Microsoft’s Chairman and CEO, Satya Nadella, stated that “AI will fundamentally change every software category, starting with the largest category of all – search.” AI copilot and chat-powered Bing and Edge will help users extract more value from search and the web.
Introducing Bing and Edge, your web copilot.
Microsoft combined search, browsing, and chat into a unified experience that you can access from any web page. New offerings include:
- Improved search. With the new Bing, you’ll enjoy a better version of the familiar search experience. You’ll get more relevant results for simple queries, such as sports scores, stock prices, and weather, and a new sidebar that displays more comprehensive answers if you want them.
- Complete answers. Bing scours the web to review results and find the answer you’re seeking. For instance, if you’re baking a cake and need to substitute eggs, you can get detailed instructions right then and there without scrolling through multiple results.
- Interactive chat. For more complex searches, like planning a detailed itinerary or researching the best TV to buy, the new Bing offers an interactive chat feature. You can refine your search by asking for more details, clarity, and ideas until you receive the complete answer you need, with links available to act on your decisions.
- Creative inspiration. Sometimes, you need more than just an answer – you need inspiration. The new Bing generates content to help you, such as helping you write an email, create a five-day itinerary for a dream vacation to Hawaii, prepare for a job interview, or create a quiz for trivia night. Additionally, Bing cites all sources, providing links to web content it references.
- Revamped Edge browser. We’ve updated the Edge browser with new AI capabilities and a new appearance. We’ve also added two new functionalities: Chat and Compose. With the Edge Sidebar, you can ask for a summary of a lengthy financial report to get the key takeaways – and then use the chat function to ask for a comparison to a competing company’s financials and automatically put it in a table. You can also ask Edge to help you compose content, such as a LinkedIn post, by giving it a few prompts to get you started. After that, you can ask it to help you update the tone, format, and length of the post. Edge understands the web page you’re on and adapts accordingly.
Revolutionizing Search with AI
The new Bing offers a revolutionary search experience that relies on four key technical advancements:
- Cutting-edge OpenAI model. Latest Bing search engine is powered by a new, advanced OpenAI language model, which is specifically designed for search and is even more powerful than ChatGPT and GPT-3.5. It incorporates significant learnings and improvements from these models, and boasts increased speed, accuracy, and capability.
- Microsoft Prometheus model. It combines unique capabilities and techniques to provide you with more targeted, timely, and relevant results, while also ensuring greater safety.
- AI-powered core search algorithm. Microsoft integrated the AI model into the core of our Bing search ranking engine, resulting in the most significant improvement in relevance in over two decades. This means that even the simplest of search queries are now more accurate and relevant.
- New user experience. Microsoft are transforming the way users engage with search, browsing, and chat by integrating them into a unified experience, unlocking a brand-new way to interact with the web. These exceptional search experiences are made possible because of Microsoft’s commitment to building Azure into a supercomputer for AI, which OpenAI has used to train these groundbreaking models optimized for Bing.

Cross-Site Scripting (XSS) is a type of security vulnerability that affects web applications. XSS allows attackers to inject malicious code into a web page viewed by other users, allowing them to steal sensitive information such as user credentials, manipulate the appearance of the web page, or perform other malicious actions.
There are two main types of XSS: stored XSS and reflected XSS. Stored XSS occurs when an attacker injects malicious code into a web page that is then stored on the server and served to all users who visit the page. Reflected XSS occurs when an attacker injects malicious code into a web page by sending it as a request to the server, which then reflects the code back to the user’s browser.
How does an XSS attack work
An XSS (Cross-Site Scripting) attack works by exploiting vulnerabilities in a web application to inject malicious code into a web page viewed by other users. The attacker’s goal is to steal sensitive information such as user credentials, manipulate the appearance of the web page, or perform other malicious actions.
Here is a general overview of how an XSS attack works:
- The attacker identifies a vulnerable web application and a web page that is vulnerable to XSS.
- The attacker crafts a malicious script that takes advantage of the vulnerability in the web page. The script is designed to execute when the web page is loaded by a user’s browser.
- The attacker injects the malicious script into the web page, either by sending a specially crafted URL to the web page that contains the malicious script, or by finding a way to store the malicious script on the web server so that it is served to all users who visit the page.
- When a user visits the infected web page, the malicious script is executed by the user’s browser. The script can steal sensitive information such as user credentials, manipulate the appearance of the web page, or perform other malicious actions.
- The attacker can then use the stolen information or perform other malicious actions as desired.
The consequences of an XSS (Cross-Site Scripting) attack can be serious for both the web application and its users. Some of the most common consequences of an XSS attack include:
- Stealing sensitive information: XSS attacks can be used to steal sensitive information such as login credentials, payment information, and other personal information from users.
- Manipulating web pages: Attackers can use XSS to manipulate the appearance of a web page, adding false information, or altering the functionality of the page.
- Spreading malware: Attackers can use XSS to spread malware, such as viruses and Trojans, to the users of a web application.
- Damaging reputation: XSS attacks can damage the reputation of a web application, leading to a loss of trust among users.
- Legal consequences: In some cases, XSS attacks can result in legal consequences, such as lawsuits or government fines.
- Loss of data privacy: XSS attacks can result in the loss of data privacy for users, as attackers can steal sensitive information and use it for malicious purposes.
How to prevent XSS attacks
It’s important for web developers to be aware of the potential consequences of XSS attacks and to take the necessary steps to prevent them, such as validating and sanitizing user input, avoiding using unsanitized data in web pages, and encoding user input properly when displaying it in web pages. Additionally, users can take steps to protect themselves from XSS attacks by keeping their web browsers up-to-date and being cautious when visiting unfamiliar websites.
By following these best practices and taking steps to prevent XSS attacks, web developers and users can help ensure the security of their web applications and protect against the potential consequences of an attack.
Where do XSS attacks most often occur
XSS (Cross-Site Scripting) attacks can occur in any web application that allows user input, but they are most commonly found in web applications that do not properly validate or sanitize user input. XSS attacks are especially prevalent in web applications that allow users to post or share content, such as forums, blogs, and social media platforms.
Other common places where XSS attacks occur include:
- Search engines: Attackers can inject malicious scripts into search results pages, allowing them to steal sensitive information from users who click on the infected results.
- Online shopping sites: Attackers can inject malicious scripts into product descriptions or reviews, allowing them to steal sensitive information from users who view the infected pages.
- Online banking and financial services: Attackers can inject malicious scripts into web pages that process financial transactions, allowing them to steal sensitive information such as login credentials and payment information.
- Web-based email services: Attackers can inject malicious scripts into emails, allowing them to steal sensitive information from users who view the infected messages.
