Our favorite 5 hacking items
1. Tips of the week
@irsdl’s #XMas2020 research notes
@eur0pa_’s method for using Burp 1.7 with the latest extensions
@irsdl has been sharing awesome hacking notes and tips on topics like deserialization bugs, WAF bypass, Burp & Fiddler, SalesForce apps security & many more. Really worth checking out!
Another noteworthy tip is for people who prefer to stay on Burp 1.7. @eur0pa_ shows how to make it work with all the latest extensions.
2. Writeups of the week
Coordinated disclosure of XML round-trip vulnerabilities in Go’s standard library
LogRhythm Zero Days
This is how I was able to view anyone’s private email and birthday on Instagram (Facebook, $13,125)
This week’s writeups are about authentication bypass in Go’s XML parser, a critical chain of WebSocket-related vulnerabilities in LogRhythm (a popular SIEM solution!) and a simple but impactful information disclosure on Instagram.
3. Video of the week
STOK Interviewed Me! 😱😱😱
I hacked Outlook and could’ve read all of your EMAILS!
Fans of @NahamSec’s interviews with hackers will love this special edition. He is the one being interviewed and answering all the usual questions on his hacker journey, life/time balance, time management, bug bounty collaboration, etc.
The second video by @ngalongc is a cool writeup of a $20k JWT bug he found in Outlook.
4. Tutorial of the week
Subdomain Takeover: Going for High Impact
@0xpatrik noticed that subdomain takeovers are harder to find nowadays and considered less dangerous because of new mitigations by cloud providers. But they’re not dead yet! If you find a subdomain takeover, make sure to increase its impact using the escalation methods he is sharing (or if you know of other ones, the community would love to hear them).
5. Resource of the week
OAuth 2.0 authentication vulnerabilities
PortSwigger just released this new Web Security Academy course on OAuth and OpenID Connect vulnerabilities. With their usual clear explanations and many labs, this is the perfect opportunity to practice or learn about OAuth hacking!
