Hi 👋

I am Isira Adithya and I am a 17 years old researcher from Sri-Lanka. Currently, Studying at Bandarawela Central College, Bandarawela.

I have a developer background (Javascript, PHP, Python, Dart, etc), When I was 13 I started developing applications in VB.Net. Since, Then I loved developing apps and other stuff like (Prank Malwares, Batch scripts, USB Viruses). Just for fun and to prank my friends.

How I got to Cyber Security

As a little kid back in the day, I was a heavy gamer with a 2GB ram. 😂
There are some missions that I cannot pass/finish without a mouse. Since I was using a Laptop, I had to use the touchpad to play games.
So, The solution was the Cheat Engine. I think you all heard about that.
I hacked every single game with that, and even hacked some softwares too. It is a 👌 tool.

Then, We got a smart television to our home and It needs a Wi-Fi network to work.
I was so eager to hack into that just like in movies 😎. Then, I installed Kali Linux without knowing anything about it and crashed my laptop too. (Whole Hard disk was corrupted 😅, and lost lots of our family photos. My father and mother was not happy about that still)

After, some googling I came across this NMAP tool and I scanned the television via this. I found some open ports and decided to attack with XERXES. And, the Television was completely stuck and didn't responded back. I had to restart it. This is another win for me, I was able to turn off the television with my laptop whenever my brother and sister don't gave me the remote. 😈

Certificates

Nothing for now. 😅

> Learning Materials

Tryhackme and Hackthebox

When It comes to my learning resources, TryHackMe and HackTheBox are some of the greatest teachers for me.

I addicted to CTF back in the day, It was so much fun for me.
Both platforms gave me a very entertaining experience while learning.
Make sure to try those platforms if you are a beginner in cyber security. (I think you already registered it. No need to introduce this. 😅) I agree that these platforms are more into penetration testing, but this knowledge will come in handy sometimes. 😉

So, Thanks a lot Tryhackme and Hackthebox.

Portswigger's Web Security Academy

This is so far the best resource to learn about web security in my opinion. 👌👌
This guides you with in-depth tutorials and it gives learning labs for free too. Further more,

Check out those too.

Timeline

2021/03/26 - Found the solution to the Intigriti 0321 XSS ChallengeAfter, 5 days of trying, I found the solution. This was a crazy moment for me, This is the first time I ever came across the XSS
2021/03/29 - I won the Intigriti 0321 XSS ChallengeAfter, found out that I won, I thought I am good at xss at least 😅. So, I watched every single youtube video about xss and I started reading through the Hackerone's Hacktivity about XSS
2021/04/06 - Reported my first valid bugI got my first private invitation in intigriti and I thought it is something very rarely happens and started digging into the web application. After about 3 days of trying came across reflected XSS. This time, I got paid 150 EUROS, It is about 35,000/- in our currency(Srilankan Rupees). It is the monthly income of my father and everyone in family was amazed about this. 😎
2021/04/11 - Got Stored XSS on the same private programI wasn't able to get XSS right away, So I reported HTML Injection and went to bed at late late night. Next, morning I decided to read about ASP WAF Bypass and Finally found a way to escalate the bug to XSS. That's why there is a bonus. 😊
2021/05/19 - Registered to Hackerone, And started hunting there too
I was hunting only XSS at the time, I never tried to find any other vulnerability like CSRF,SSRF,RCE etc. Because of that, I wasn't able to find a single valid bug since 2021/04/11, after I started with hackerone, I started to learn more bugs via Portswigger's Web Security Academy.
2021/05/21 - 2021/06/10 - Reported various bugs to Hackerone
2021/06/09 - Found a High Severity bug on a big companyThis was resolved within 7 hours, even before hackerone triage team reaches. This was a super exciting bug for me and this bug is not documented anywhere. Basically, I was able to takeover an subdomain in use.(Varnish Cache Server Misconfiguration)
2021/07/13 - Got to the 5# in the Intigriti Last 30 days Leaderboard
