BUG BOUNTY FOR BEGINNERS
Even in the age of AI fastlane, you need sound foundational knowledge. Let me hold your hands.

Dear beginner,

Bug bounty hunting can feel like a firehose of information at first, so breaking it down into distinct paths makes the journey much more manageable.
As a next step, many beginners find it helpful to pick just one of the following classes to focus ...

@Zer0day_sec Most of bus have. Saddest experience

[0xdEb @i0xdEb]

@iseewithmybrain @Abramdango01 AI. A very good tool.
You could use this to speak against national evil of politicians and ills of society. Do good.
Comedy is not bad, but we need more art for good

YOUR EXCLUSIONS - AN ATTACKER'S HAPPY PATH

Amessage to every protocol with a 10-page out-of-scope list. You think you are limiting researcher reports. You are actually publishing an attacker's roadmap.

Every exclusion on your scope list is an implicit announcement:
"We have decided not to defend this surface."
And attackers read scope lists too.

The most dangerous exclusions in bug bounty programs today:

☆ Centralization / single points of failure: "Trusted role, out of scope." Bybit lost $1.5B to exactly this. The researcher who flagged it got nothing. The attacker who found it got everything.

☆ Admin key compromise: "Assumed trusted, out of scope." Every insider job in Web3 history lived behind this exclusion. The team called it trust. The attacker called it access.

☆ Known issues, "Already acknowledged, out of scope." Known to whom? If it is known and unfixed, it is not out of scope. It is a liability with a timestamp.

☆ Economic / governance attacks: "Design decision, out of scope." Mango Markets. $100M. Design decision exploited.

☆ Frontend / UI issues: "Out of scope." Until a DNS hijack drains your users' wallets through your own interface.

☆ Third party dependencies: "Not our code, out of scope." It is your integration, your design choice. It is your users' funds. It is your postmortem.

☆ All forms of DoS: "No direct fund loss, out of scope." A denial of service attack that freezes a bridge, blocks withdrawals during a market crash, or prevents liquidations from executing is not a minor inconvenience. It is a weapon. DoS that halts protocol operations long enough for cascading failures is indistinguishable in outcome from a direct drain, except the attacker never touched a single token. Unavailability is a loss vector. Treat it like one.

☆ Theoretical vulnerabilities without PoC: "Unproven, out of scope." Some of the most critical findings in Web3 history were theoretical, until they weren't.

Here is the uncomfortable truth:
Every item you exclude from scope because it is inconvenient to fix (or you just don't want to pay bounty) IS A DOOR you have chosen to leave open.

Researchers walk away when they see it out of scope.
Attackers walk in.

The out-of-scope list is not a liability shield.
It is a prioritised list of your undefended surfaces, published publicly, for anyone willing to read it carefully.
The attacker does not respect your scope list.
They study it.

A well-scoped bug bounty program is not just generous to researchers.
It is a statement of genuine security intent.

Narrow scope = narrow coverage = wide open attack surface.
DoS, centralization, admin keys, governance, dependencies, all roads lead to the same destination when left undefended.
The attacker just picks the one you marked out of scope. 🔍

REVIEW YOUR EXCLUSIONS NOW!
Not for the researcher's sake. But for you, for your users'. 🔍🎩

@Stupidity_KNB @HumansNoContext Best comment

[0xdEb @i0xdEb]

@cyber__razz Agreed 💯

[0xdEb @i0xdEb]

@Zer0day_sec Fixed?

[0xdEb @i0xdEb]

@matt_leho @IntCyberDigest Plus, you INSTRUCTED it

[0xdEb @i0xdEb]

@matt_leho @IntCyberDigest Thats a rogue situation. If the hacking uses your IP, you're responsible.

[0xdEb @i0xdEb]

@grok @zizerr_web3 @IntCyberDigest Oh my... 🤔

Welcome to Immunefi, @cosmoslabs_io.

One of the foundational Layer 1 stacks in crypto is bringing its bug bounty program to the largest security researcher community in Web3.

Excited for what the next 90 days will show. 🔥

[0xdEb @i0xdEb]

@immunefi @cosmoslabs_io Good news

[0xdEb @i0xdEb]

@cosmoslabs_io @immunefi A better experience for security researchers. Noted.
