Found a hidden HTTP param? Look deeper, maybe there is a mass assignment/autobinding vulnerability. Sometimes changes in objects are hidden too and you need to closely explore the app. Source: itzone.com.vn/en/article/mas… #CyberSecurity #BugBountyTip #BugBounty

CSRF in 120 seconds! As you remember Cookies without SameSite are treated as SameSite=LAX in Chrome. But there is one exception that can be used as a temporary policy bypass. More detailed examples: medium.com/@renwa/bypass-sam… by @RenwaX23 #CyberSecurity #BugBountyTip #BugBounty

Using other hosts as a gateway, sometimes, you can get access to other VLANs or bypass the firewall. That is a task for gateway-finder! Check the improved version by @whitel1st: github.com/whitel1st/gateway… #CyberSecurity #Pentest #RedTeam

Were you surprised when your cross-domain attack didn't work? Meet the new reality with SameSite Cookies. Now Chrome and Safari recognize Cookies without the SameSite attribute as SameSite=Lax by default. #CyberSecurity #BugBounty #BugBountyTip

There are a lot of known vulnerabilities in Cisco. But available Cisco Smart Install is our favorite. This one helped us in few red teams and even bug bounty. Thanks to @sab0tag3d for an awesome exploit github.com/Sab0tag3d/SIET #redteam #pentest #cybersecurity

WebSocket is a widespread technology in modern Web. Incorrect implementation can lead to a simple but critical vulnerability – WebSocket Hijacking. Example: hackerone.com/reports/535436 Try it in the @PortSwigger Lab: portswigger.net/web-security… #BugBountyTip #CyberSecurity #BugBounty

There is a popular opinion: bad CORS like <Access-Control-Allow-Origin: *> is unexploitable. Browser won't send cookies in this case. It is a delusion. You can exploit it with a Chrome cache feature! For example: hackerone.com/reports/761726 #BugBountyTip #CyberSecurity #BugBounty
