Webhooks are one of a few ways internet applications will communicate with one another.It allows you to send real-time data from one application to another whenever a given event happens.For example, let's say you've created an application using the Foursquare API that tracks when people check into your restaurant. You ideally wish to be able to greet customers by name and provide a complimentary drink when they check in.What a webhook will is notify you any time someone checks in, therefore you'd be able to run any processes that you simply had in your application once this event is triggered.The data is then sent over the web from the application wherever the event originally occurred, to the receiving application that handles the data.Here's a visual representation of what that looks like:      A webhook url is provided by the receiving application, and acts as a phone number that the other application will call once an event happens.Only it's more complicated than a phone number, because data about the event is shipped to the webhook url in either JSON or XML format. this is known as the "payload." Here's an example of what a webhook url looks like with the payload it's carrying:     What are Webhooks? Webhooks are user-defined HTTP callback or push APIs that are raised basedon events triggered, such as comment received on a post and pushing code to the registry. Awebhook allows an application to update other applications with the latest information. Onceinvoked, it supplies data to the other applications, which means that users instantly receive real-timeinformation. Webhooks are sometimes called "Reverse APIs" as they provide what is required for APIspecification, and the developer should create an API to use a webhook. A webhook is an APIconcept that is also used to send text messages and notifications to mobile numbers or email addresses from an application when a specific event is triggered. For instance, if you search for something in the online store and the required item is out of stock, you click on the "Notify me" bar to get an alert from the application when that item is available for purchase.These notifications from the applications are usually sent through webhooks.

https://www.eccouncil.org/what-is-social-engineering/This Social Engineering scam involves an exchange of information that can benefit both the victim and the trickster. Scammers would make the prey believe that a fair exchange will be present between both sides, but in reality, only the fraudster stands to benefit, leaving the victim hanging on to nothing. An example of a Quid Pro Quo is a scammer pretending to be an IT support technician.The con artist asks for the login credentials of the company's computer saying that the company is going to receive technical support in return. Once the victim has provided the credentials, the scammer now has control over the company's computer and may possibly load malware or steal personal information that can be a motive to commit identity theft."A quid pro quo attack (aka something for something" attack) is a variant of baiting. Instead of baiting a target with the promise of a good, a quid pro quo attack promises a service or a benefit based on the execution of a specific action."https://resources.infosecinstitute.com/topic/commonsocial- engineeringattacks/#:~: text=A%20quid%20pro%20quo%20attack,execution%20of%20a%20specific%20action.

Out-of-band SQL injection occurs when an attacker is unable to use an equivalent channel to launch the attack and gather results. ... Out-of-band SQLi techniques would believe the database server's ability to form DNS or HTTP requests to deliver data to an attacker. Out-of-band SQL injection is not very common, mostly because it depends on features being enabled on the database server being used by the web application. Out-of-band SQL injection occurs when an attacker is unable to use the same channel to launch the attack and gather results.Out-of-band techniques, offer an attacker an alternative to inferential time-based techniques, especially if the server responses are not very stable (making an inferential time-based attack unreliable).Out-of-band SQLi techniques would rely on the database server's ability to make DNS or HTTPrequests to deliver data to an attacker. Such is the case with Microsoft SQLServer's xp_dirtree command, which can be used to make DNSrequests to a server an attackercontrols; as well as Oracle Database's UTL_HTTP package, which can be used to send HTTP requestsfrom SQL and PL/SQL to a server an attacker controls.
