If you're learning bug bounty and feel like everyone else is finding vulnerabilities while you can't find anything, that does not necessarily mean you're bad at hacking.
The security landscape has changed.
Some vulnerabilities that were easier to find years ago are now less common, better protected, or discovered much faster. Developers have better security practices, modern frameworks handle more common mistakes, and AI-assisted coding has also changed how quickly basic vulnerabilities can be introduced and fixed.
At the same time, many of the impressive bug bounty reports you see today come from researchers with years of experience, access to private programs, or knowledge built through thousands of hours of testing.
So comparing your first months of hunting with someone's strongest public reports from years ago can give you a very distorted picture.
Some reports from around 2020 show vulnerabilities involving relatively straightforward issues such as:
The difference is that the surrounding security environment has become more mature.
Applications have better frameworks, more security testing, stronger authorization controls, and more automated protection.
That doesn't mean old vulnerability classes disappeared.
It means finding them can require more patience and a deeper understanding of how modern applications work.
The important lesson isn't the specific endpoint.
It's the underlying security problem:
The server trusted an operation that the user's permissions should not have allowed.
This is a classic example of why API testing should go beyond checking whether an endpoint works.
A researcher should also ask:
The basic concept behind an IDOR is simple:
An application uses an identifier to decide which object should be modified or accessed, but the server fails to verify that the current user actually owns or is authorized to access that object.
For example, an application might conceptually use:
Changing that identifier should never be enough to access another user's data.
The server must perform an authorization check.
This becomes much more serious when the vulnerable object contains security-sensitive information.
If an attacker can modify an email address or another account-recovery field, an authorization bug can potentially become an [B>account takeover[/B] rather than remaining a simple data-access issue.
That's an important bug bounty lesson:
Don't stop at the first impact you discover.
If you find unauthorized access to an object, ask what actions become possible because of that access.
One of the older examples referenced in the original post involved a parameter used to search or retrieve articles. The researcher identified behavior consistent with a time-based SQL injection and reported it.
The important lesson isn't the exact payload.
It's understanding what the researcher was testing:
Can user-controlled input influence a database query in a way the application doesn't safely control?
Modern applications often use parameterized queries, ORMs, input validation, and other protections that make traditional SQL injection less common.
But SQL injection hasn't disappeared.
It can still occur when developers construct database queries incorrectly, especially around:
That illustrates an important point about web security:
Every user-controlled input is potentially part of the application's attack surface.
Depending on the application, user-controlled data can appear in:
But researchers still need to understand the entire data flow:
Input → processing → storage → output → browser
The interesting question isn't simply: "Can I insert HTML here?"
It's: "Where does this data go, how is it processed, and under what context is it eventually rendered?"
That way of thinking scales much better than testing random fields.
When you look through old bug bounty reports, you may see researchers finding vulnerabilities that appear incredibly simple.
You might think:
You aren't seeing:
A public report is not a complete representation of someone's ability.
It's a snapshot of one successful result.
Bug bounty platforms have changed over time, and researchers have had different paths into private programs and training opportunities.
The original post mentions a HackerOne training experience referred to as Hacker101 and describes a previous path from completing challenges to receiving private-program invitations.
Whether or not a specific historical pathway is still available in the same form, the broader lesson remains useful:
Access to good targets can have a major effect on how quickly a researcher develops.
A beginner testing random public targets isn't necessarily operating under the same conditions as an experienced researcher who has access to private programs and mature testing environments.
That's why comparing results without considering the environment can be unfair.
The developers are improving. 👨💻
Modern development teams have access to:
AI can still generate vulnerable code, but it can also help developers identify and fix many common programming mistakes.
That means some basic vulnerabilities may be found and corrected before an application reaches production.
For a bug hunter, this can raise the bar.
The easy vulnerability may have disappeared.
The remaining vulnerability may require a deeper understanding of the application's architecture and business logic.
That's not really the right way to look at it.
Security research is cumulative.
You don't need to master everything before you can start finding meaningful vulnerabilities.
Instead, build your skills layer by layer.
For example:
The goal is to understand how applications behave well enough to notice when something doesn't make sense.
You find a researcher who has published:
That's rarely useful.
A researcher who has spent years hunting has already built an enormous library of mental patterns.
They may recognize a suspicious API parameter in seconds because they've seen the same design mistake dozens of times.
You may need an hour to understand what you're looking at.
That's not failure. That's the learning process. 🧠
Finding vulnerabilities is partly about skill and partly about opportunity.
You can test an endpoint today and find nothing.
Another researcher may have tested the same endpoint a year earlier and found a vulnerability because the application was different at that time.
A parameter that is secure today may have been vulnerable in the past.
A feature that looks interesting may already have been tested by hundreds of researchers.
And a private program may contain a vulnerability that simply isn't visible to researchers outside that program.
This doesn't make skill irrelevant.
It means results are not a perfect measurement of ability.
Look at your process.
Ask yourself:
It's your methodology.
You might spend weeks finding nothing.
Then suddenly recognize a pattern that you previously couldn't see.
The next time you encounter a similar application, you notice it much faster.
That's real progress, even if it doesn't immediately produce a bounty.
Eventually, individual concepts start connecting:
HTTP + APIs + authorization + application logic + recon + testing = better vulnerability discovery.
That's when hunting starts to feel different.
Remember that you're looking at a different time, different applications, different security practices, different competition, and often a different level of access.
The fact that someone found an IDOR years ago doesn't mean you're bad because the same parameter is protected today.
The fact that someone found an XSS in a profile field doesn't mean you're doing something wrong when the same field is properly encoded now.
And the fact that another hunter is finding bugs doesn't mean you're incapable of finding them.
The environment changes.
The targets change.
The competition changes.
And you change too. 🚀
You may start with duplicates and informational findings.
Then you understand authorization.
Then APIs.
Then business logic.
Then you start seeing things that other people miss.
That's how the skill develops.
Don't judge your ability by someone else's best report. Judge it by how much you understand today that you didn't understand a few months ago.
Bug bounty is a long game.
Keep learning, keep testing responsibly, and give yourself enough time to get better.
Your next valid finding might be closer than you think. 🔐

So comparing your first months of hunting with someone's strongest public reports from years ago can give you a very distorted picture.
Bug Bounty Was Different a Few Years Ago
Looking at older public reports can be surprisingly useful.Some reports from around 2020 show vulnerabilities involving relatively straightforward issues such as:
- Broken access control
- Account takeover
- SQL injection
- Cross-site scripting (XSS)
- Insecure direct object references (IDOR)
- Weak API authorization
- Unexpected application behavior
The difference is that the surrounding security environment has become more mature.
Applications have better frameworks, more security testing, stronger authorization controls, and more automated protection.
That doesn't mean old vulnerability classes disappeared.
It means finding them can require more patience and a deeper understanding of how modern applications work.
A Simple API Permission Bug Could Become a Major Finding
One example from the original discussion involved a HackerOne report where a researcher found an API behavior that allowed a report's state to be changed in a way that should not have been available to that user.The important lesson isn't the specific endpoint.
It's the underlying security problem:
The server trusted an operation that the user's permissions should not have allowed.
This is a classic example of why API testing should go beyond checking whether an endpoint works.
A researcher should also ask:
- Who is allowed to perform this action?
- Does the server verify that permission?
- Does changing a parameter change the authorization context?
- Are different workflow states protected consistently?
- Does the API enforce the same rules as the web interface?
IDOR Can Become Account Takeover
Another example involved an IDOR (Insecure Direct Object Reference) that affected account information.The basic concept behind an IDOR is simple:
An application uses an identifier to decide which object should be modified or accessed, but the server fails to verify that the current user actually owns or is authorized to access that object.
For example, an application might conceptually use:
user_id to identify an account.Changing that identifier should never be enough to access another user's data.
The server must perform an authorization check.
This becomes much more serious when the vulnerable object contains security-sensitive information.
If an attacker can modify an email address or another account-recovery field, an authorization bug can potentially become an [B>account takeover[/B] rather than remaining a simple data-access issue.
That's an important bug bounty lesson:
Don't stop at the first impact you discover.
If you find unauthorized access to an object, ask what actions become possible because of that access.
SQL Injection Used to Be a Common Discovery Path
SQL injection is another classic vulnerability class.One of the older examples referenced in the original post involved a parameter used to search or retrieve articles. The researcher identified behavior consistent with a time-based SQL injection and reported it.
The important lesson isn't the exact payload.
It's understanding what the researcher was testing:
Can user-controlled input influence a database query in a way the application doesn't safely control?
Modern applications often use parameterized queries, ORMs, input validation, and other protections that make traditional SQL injection less common.
But SQL injection hasn't disappeared.
It can still occur when developers construct database queries incorrectly, especially around:
- Legacy code
- Custom query builders
- Dynamic filtering
- Search functionality
- Reporting systems
- Poorly reviewed database interfaces
XSS Was Everywhere in Older Applications
The original discussion also mentioned finding XSS in many different input locations.That illustrates an important point about web security:
Every user-controlled input is potentially part of the application's attack surface.
Depending on the application, user-controlled data can appear in:
- Profiles
- Email fields
- Company names
- File names
- Image metadata
- Messages
- Search parameters
- URL parameters
But researchers still need to understand the entire data flow:
Input → processing → storage → output → browser
The interesting question isn't simply: "Can I insert HTML here?"
It's: "Where does this data go, how is it processed, and under what context is it eventually rendered?"
That way of thinking scales much better than testing random fields.
Why Older Reports Can Be Misleading
This is probably the most important part.When you look through old bug bounty reports, you may see researchers finding vulnerabilities that appear incredibly simple.
You might think:
But you're seeing the successful report.
You aren't seeing:
- The thousands of failed requests
- The hours spent understanding the application
- The duplicate reports
- The targets that were already patched
- The private programs you couldn't access
- The vulnerabilities other researchers found first
- The years of experience behind the researcher
A public report is not a complete representation of someone's ability.
It's a snapshot of one successful result.
The Bug Bounty Environment Has Changed
The original discussion also points to another important difference: access to private programs.Bug bounty platforms have changed over time, and researchers have had different paths into private programs and training opportunities.
The original post mentions a HackerOne training experience referred to as Hacker101 and describes a previous path from completing challenges to receiving private-program invitations.
Whether or not a specific historical pathway is still available in the same form, the broader lesson remains useful:
Access to good targets can have a major effect on how quickly a researcher develops.
A beginner testing random public targets isn't necessarily operating under the same conditions as an experienced researcher who has access to private programs and mature testing environments.
That's why comparing results without considering the environment can be unfair.
Developers Are Getting Better Too
There's another side of the equation that bug hunters sometimes overlook.The developers are improving. 👨💻
Modern development teams have access to:
- Better security frameworks
- Secure coding guidelines
- Automated testing
- SAST and DAST tools
- Dependency scanners
- Cloud security controls
- Security-focused CI/CD pipelines
- Code review systems
- AI-assisted development tools
AI can still generate vulnerable code, but it can also help developers identify and fix many common programming mistakes.
That means some basic vulnerabilities may be found and corrected before an application reaches production.
For a bug hunter, this can raise the bar.
The easy vulnerability may have disappeared.
The remaining vulnerability may require a deeper understanding of the application's architecture and business logic.
This Doesn't Mean You Need to Be Five Times Smarter
It's easy to look at all of this and think: "People used to need one skill. Now I need five."That's not really the right way to look at it.
Security research is cumulative.
You don't need to master everything before you can start finding meaningful vulnerabilities.
Instead, build your skills layer by layer.
For example:
- Learn HTTP and how web applications communicate.
- Understand authentication and authorization.
- Learn how APIs work.
- Study common vulnerability classes.
- Learn how applications store and process user input.
- Practice identifying broken assumptions.
- Study real vulnerability reports.
- Learn basic scripting and automation.
- Understand common application architectures.
- Gradually move toward business-logic vulnerabilities.
The goal is to understand how applications behave well enough to notice when something doesn't make sense.
Don't Measure Yourself Against Someone Else's Best Reports
This is where many beginners get discouraged.You find a researcher who has published:
- Critical vulnerabilities
- Account takeovers
- SQL injection
- SSRF
- XSS
- Large payouts
- Private-program findings
That's rarely useful.
A researcher who has spent years hunting has already built an enormous library of mental patterns.
They may recognize a suspicious API parameter in seconds because they've seen the same design mistake dozens of times.
You may need an hour to understand what you're looking at.
That's not failure. That's the learning process. 🧠
Bug Bounty Is Also About Timing and Opportunity
There is another uncomfortable truth about bug bounty:Finding vulnerabilities is partly about skill and partly about opportunity.
You can test an endpoint today and find nothing.
Another researcher may have tested the same endpoint a year earlier and found a vulnerability because the application was different at that time.
A parameter that is secure today may have been vulnerable in the past.
A feature that looks interesting may already have been tested by hundreds of researchers.
And a private program may contain a vulnerability that simply isn't visible to researchers outside that program.
This doesn't make skill irrelevant.
It means results are not a perfect measurement of ability.
What You Should Focus on Instead
If you're struggling to find bugs, don't immediately conclude that you're not good enough.Look at your process.
Ask yourself:
- Am I spending enough time understanding the target?
- Do I understand the application's authentication model?
- Do I understand how users and objects relate to each other?
- Am I testing APIs, not just the frontend?
- Do I understand authorization?
- Am I studying how real vulnerabilities were caused?
- Do I keep notes about what I've tested?
- Am I learning from failed tests?
- Am I spending enough time on one target to understand its behavior?
It's your methodology.
Your Progress May Be Hard to Notice
Bug bounty progress is rarely linear.You might spend weeks finding nothing.
Then suddenly recognize a pattern that you previously couldn't see.
The next time you encounter a similar application, you notice it much faster.
That's real progress, even if it doesn't immediately produce a bounty.
Eventually, individual concepts start connecting:
HTTP + APIs + authorization + application logic + recon + testing = better vulnerability discovery.
That's when hunting starts to feel different.
The Biggest Lesson
If you look at old bug bounty reports and think: "How were people finding bugs this easily?"Remember that you're looking at a different time, different applications, different security practices, different competition, and often a different level of access.
The fact that someone found an IDOR years ago doesn't mean you're bad because the same parameter is protected today.
The fact that someone found an XSS in a profile field doesn't mean you're doing something wrong when the same field is properly encoded now.
And the fact that another hunter is finding bugs doesn't mean you're incapable of finding them.
The environment changes.
The targets change.
The competition changes.
And you change too. 🚀
You may start with duplicates and informational findings.
Then you understand authorization.
Then APIs.
Then business logic.
Then you start seeing things that other people miss.
That's how the skill develops.
Don't judge your ability by someone else's best report. Judge it by how much you understand today that you didn't understand a few months ago.
Bug bounty is a long game.
Keep learning, keep testing responsibly, and give yourself enough time to get better.
Your next valid finding might be closer than you think. 🔐
