OAuth | Breaking Cybersecurity News | The Hacker News

There are more than 100 Million users who are using Facebook mobile app. Facebook has fixed multiple critical vulnerabilities in its Android based applications that allows hackers to steal access tokens and hijack accounts. Egyptian security researcher Mohamed Ramadan, Security researcher with Attack Secure, has who disclosed  a couple of vulnerabilities in the Facebook Main app and Facebook messenger app and Facebook page's manager application for Android. User's access token is the key to accessing a Facebook account and according to him, an attacker only needs to send a message that contains an attachment of any type, i.e. Videos, documents, and pictures. Once the victim will click on that file to download, immediately victim's access_token will be stored in the Android's log messages called -  logcat ,  that enables other apps to grab user's access token and hijack the account.

In recent few months White hat Hacker ,' Nir Goldshlager ' reported many critical bugs in Facebook OAuth  mechanism, that allowed an attacker to hijack any Facebook account without user's interaction.  Another hacker, ' Amine Cherrai ' reported a new Facebook OAuth flaw, whose exploitation is actually very similar to Nir Goldshlager 's findings but with a new un-patched way. Before reading further, I would like to suggest you to read following post to understand the basic exploitation mechanism: Facebook OAuth flaw allows gaining full control over any Facebook account Facebook hacking accounts using another OAuth vulnerability URL Redirection flaw in Facebook apps push OAuth vulnerability again in action Now, if you are aware about the vulnerability used against Facebook OAuth in  redirect_uri parameter in  the URL, there is another way that  Amine Cherrai found, to bypass the patch applied by Facebook  security team. He found another

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1. Know Thy Endpoints: Identifying and Understanding Your Entry Points Understanding your network's

Facebook OAuth is used to communicate between Applications & Facebook users, to grant additional permissions to your favorite apps. To make this possible, users have to ' allow or accept ' the application request so that app can access your account information with required permissions. As a normal Facebook user we always think that it is better than entering your Facebook credentials, we can  just allow specific permissions to an app in order to make it work with your account. Today whitehat Hacker ' Nir Goldshlager ' reported ' The Hacker News ' that he discovered a very critical vulnerability in Facebook's OAuth system, that allowed him to get full control over any Facebook account easily even without ' allow or accept ' options. For this purpose he hunt the flaw in a very mannered way i.e Step 1) Understanding the OAuth URL Step 2) Finding a way to use custom parameters in URL Step 3) Bypassing OAuth ' Allow '
