Top 3 Linux commands for quick privilege escalation checks: 1. find / -perm -4000 -type f 2>/dev/null (Find SUID binaries) 2. sudo -l (Check current user sudo permissions) 3. cat /etc/crontab (Look for misconfigured cron jobs) Simple, fast, and works on almost every Linux box. #Linux #EthicalHacking #CyberSecurity #BugBounty
Summary checklist for your recon toolkit: ✅ Keep version intensity low for stealth ✅ Filter NSE scripts by 'safe' tag ✅ Combine SYN + ICMP for host discovery Save this thread for your next pentest or bug bounty target 📌
3/ Fast Host Discovery via Multi-Probe Scanning
Quick host discovery on large IP ranges:
nmap -sn -PE -PP -PS21,22,80,443,3389
Most beginners fail at network recon because they blindly run "nmap -A" against every target and get blocked by WAFs. To find real vulnerabilities in 2026, you need targeted scan flags that bypass basic rate limiting. Here are 6 essential Nmap techniques top bug bounty hunters use 🧵👇
@qwen_cloud @arena yo Qwen-Image-3.0 just dropped and it’s already cooking #1 Chinese model + top tier overall is no joke 4.5k token prompts that can do full newspapers and exam papers in one go? that’s actually insane text legibility looking clean too
@swyx @_chenglou @midjourney @coyle_frankp @emileifrem damn this is so true “good enough” ai finally being dirt cheap is exactly why graphs and ontologies are popping off now 3 years ago this shit was just theory, now it’s actually useful love the aha moment from the meetup.
@vxunderground Bro Helen out here doing the Lord’s work while vx is locked in the basement like a true malware goblin 😂 Defcon about to smell like fresh goop and bad decisions. Respect.
Hard truth in cybersecurity: Recon is 80% of bug bounty hunting. If you spend 10 minutes scanning and immediately jump to exploitation, you're competing with thousands of script kiddies. The real bugs are found in the forgotten subdomains and hidden API endpoints everyone else missed. Agree or disagree? #CyberSecurity #BugBounty #InfoSec #Pentesting
3 OSINT techniques most beginners overlook: 1. Searching indexed public AI chat URLs for leaked corporate API keys. 2. Checking certificate transparency logs (crt.sh) for forgotten subdomains. 3. Using Shodan filters to catch exposed staging servers before production. Which one do you use the most in your workflow? #OSINT #CyberSecurity #InfoSec #BugBounty
@elonmusk The architectural detail and lighting control are impressive. Grok Imagine is getting strong at coherent interior spaces.
@elonmusk The legal battle is getting more aggressive. Preliminary injunction and forensic supervision requests show how serious Apple is taking this.
@elonmusk If Grok can generate playable games at this visual quality, it opens up a completely new category.
@iruletheworldmo Fair observation. Once the shifts start coming more frequently, the pace of change becomes harder to track in real time.
@bridgemindai Delayed launches usually mean they’re still improving it. A strong 3.5 Pro would put real pressure back on the current leaders.
What you should do today: 1. Restrict public internet access on ALL admin consoles (IP whitelist or VPN only). 2. Treat your AI integrations & MCP bridges like production APIs (isolate permissions). 3. Stop treating CVSS scores equal—prioritize CISA KEV zero-days first. Stay safe out there. What’s your team’s patching ETA looking like this week?
Third issue: Public AI Share Leaks. Engineers are pasting internal code, API keys, and system architecture into AI tools, then hitting "Share". Search engines are now indexing these public URLs. Threat actors don't even need zero-days anymore—they’re literally googling for valid enterprise credentials.
If you work in SOC or DevSecOps, your week just got a lot harder. CISA dropped BOD 26-04 enforcing a strict 3-day emergency patching deadline for critical KEV zero-days. Why the rush? Attackers are using AI recon tools to shrink exploit timelines from months to literally hours. Here’s what’s actually happening behind the scenes 👇
