anthropic shipped claude opus 4.7 with a new cyber classifier four days ago. hackerone pays up to $15k per universal jailbreak. one solo operator used roleplay prompts on 4.5 to exfil 150GB from the mexican government. guide drops the taxonomy. #AISecurity #RedTeam

absolutely lol. great call out.
ever report a bug and immediately think “i should’ve saved that one for later”? #bugbounty
Caffeine intake is directly proportional to triage response time. #BugBounty #InfoSec
every time i see a 500 error, i feel like i just poked something i wasn’t supposed to. #bugbounty
spent all night fuzzing only to realize the app was down for maintenance. #bugbounty
researchers pwned claude code, gemini cli, and copilot agent with a pr title.
johns hopkins team put #prompt injection into a pull request title. the agents read it, followed it, and in claude’s case leaked what could be #credentials through the review comment.
#anthropic paid $100.
Cuckoo’s Egg Log Chase (1986) – Astronomer-turned-sysadmin Cliff Stoll traced a 75-cent accounting error to an East-German spy ring stealing U.S. military secrets; armed only with a modem and a spiral notebook. #Hackers
red team lives in kali, blue team lives in splunk, neither sleeps. #infosec
the morris worm taught everyone that “oops” can be a global event. #hackerhistory
bug bounty tip: the best findings are usually hiding behind one extra click. #bugbounty
triagers must have a folder called “not reproducible.” #bugbounty
If you had to disable one standard service on every freshly deployed server, which would it be?
#ServerManagement #TechDebate
Correlate with business logic.
Think like the app owner: can you transfer credits, bypass approvals, or alter invoices? High-impact logic flaws often sit outside classic vuln checklists. #BugBounty
The Dark Tangent’s Pager Hack (1993) – At the very first DEF CON, founder Jeff Moss demonstrated pager cloning to show how “private” beeper messages could be intercepted in real time. #Defcon
#Claude #Mythos Preview won’t be release to the general public ⚠️
only a special set of defense partners known as Project #Glasswing will get the model.
Anthropic sites an unprecedented jump in cyber capability that is dangerous to release in the current form.

bug hunting is basically speed dating with error messages. #bugbounty
If you could magically enforce one security control across the internet, what would it be?
every payload works in repeater until you show it to the triager. #bugbounty
The very first webcam (1991) pointed at a coffee pot at Cambridge so sysadmins knew when to refill it. #IT
i think bug hunting taught me more about debugging than dev ever did. #bugbounty
That moment when grep finds the secret in node_modules—and you can’t decide whether to celebrate or cry. #infosec
red teamers call it “initial access.” blue team calls it “a very bad day.” #infosec
why do all the juicy endpoints have the worst error messages? #bugbounty
An app feels safe until you examine it closely. #CyberSecurity #AppSafety
Consider the business logic: could you move credits, skip approvals, or modify invoices? Major logic flaws often lurk beyond standard vulnerability lists. #CyberSecurity
Every exposed inference endpoint is a training set for attackers.
High-volume, carefully crafted queries let them clone outputs and rehost your model.
Rate-limit, add noise, and watch for scraping signals.

How do you keep motivation up during those endless triage silences? #Triage
nobody scans ports to hack an AI agent. one poisoned document in the RAG pipeline and the model does the rest. NVIDIA and MITRE ATLAS mapped 66+ #AISecurity attack techniques. here's where the chain breaks. #PromptInjection #MLSec

Map first, hack second.
Use tools like amass, subfinder, or assetfinder to build a full subdomain list, then verify with httpx or httprobe. A wide, clean recon set is where 80% of finds begin. #BugBounty
