Introduction:
Most security professionals attend conferences with a rigid agenda: specific talks, vendors, or certifications. But as Joshua Copeland’s unpopularopinion illustrates—using a rock concert where the openers stole the show—the highest-value collisions often happen outside the planned itinerary. In cybersecurity, this translates to hallway conversations, impromptu problem-solving sessions, and discovering niche tools that solve your exact internal challenges, not the generic ones marketed from a keynote stage.
Learning Objectives:
- Design a “collision agenda” that prioritizes unexpected value over scheduled sessions
- Build a real-time threat intelligence gathering framework using open-source tools and offline networking
- Automate post-conference lead and insight enrichment with Linux/Windows scripts
You Should Know:
- Building a Collision-First Conference Toolkit (Linux & Windows)
The post emphasizes “getting in the room” with a collision agenda: 3 problems to validate, 3 people to meet, 3 ideas to bring back, and 1 business decision. To operationalize this, create a digital field kit that captures serendipity without friction.
Step-by-step guide – Pre-conference environment setup:
Linux (Debian/Ubuntu):
Create encrypted directory for conference intel sudo apt-get install cryptsetup -y mkdir ~/bsides_collisions sudo cryptsetup luksFormat ~/collisions.img 100MB secure container sudo cryptsetup open ~/collisions.img collision_mount Install note-taking and OCR tool sudo apt-get install tesseract-ocr tmux jq -y
Windows (PowerShell as Admin):
Create secure vault using BitLocker and set up OneNote CLI hooks New-Item -Path "$env:USERPROFILE\bsides_kit" -ItemType Directory Enable-BitLocker -MountPoint "$env:USERPROFILE\bsides_kit" -EncryptionMethod XtsAes256 Install-PackageProvider -Name NuGet -Force Install-Script -Name ps2txt -Force
Usage: Before entering the conference, set up a tmux session (Linux) or Windows Terminal split panes. One pane runs a live `tcpdump` of the venue’s open Wi-Fi (with permission, for threat hunting), another pane captures voice-to-text notes via `arecord | luis` (Linux) or Windows Dictation. This turns ad-hoc hallway chats into searchable intelligence.
2. Extracting Technical Value from “Unplanned” Encounters
Copeland notes: “A startup building something weirdly close to the problem you have been trying to solve internally.” To validate such solutions on the spot, deploy a portable assessment script on a Raspberry Pi or a Windows laptop.
Live startup tool evaluation – Linux:
Clone and run basic vulnerability check on the startup’s demo API git clone https://github.com/securego/gosec.git cd gosec ./gosec -no-fail -fmt=json -out=api_scan.json https://startup-demo.com/api/v1 Use nuclei for quick CVE match nuclei -target https://startup-demo.com -severity high,critical -o demo_findings.txt
Windows (PowerShell):
Invoke REST method and run simple API security headers check
$response = Invoke-WebRequest -Uri "https://startup-demo.com/api/v1" -Method Get
$response.Headers
Check for missing HSTS, CSP, X-Frame-Options
if ($response.Headers['Strict-Transport-Security'] -eq $null) {
Write-Warning "No HSTS – startup ignoring transport security"
}
What this does: It immediately identifies whether a promising “weird” solution introduces common vulnerabilities (missing security headers, open S3 buckets, debug endpoints). You can then engage the founder with real findings, moving from small talk to a design partnership—exactly the value Copeland describes.
- The “Hallway Threat Hunt” – Capturing Ambient Intel
Regional conferences often have less sanitized network environments than major events. Use this to practice passive reconnaissance and hone your blue team reflexes.
Linux – Monitor rogue access points and deauth attempts:
sudo airmon-ng start wlan0
sudo airodump-ng wlan0mon --write bsides_capture --output-format csv
Extract suspicious SSIDs (e.g., "Free_WiFi", "Conference_Staff")
grep "WPA" bsides_capture-01.csv | awk -F',' '{print $14}' | sort -u
Windows – Use netsh to log nearby Wi-Fi probes (forensic value):
netsh wlan show networks mode=bssid > conference_networks.txt Monitor for Evil Twin attacks – compare BSSIDs every 15 mins :loop netsh wlan show networks mode=bssid | findstr /i "SSID" >> diff_log.txt timeout /t 900 goto loop
Step-by-step guide for responsible disclosure:
- Step 1: Obtain written consent from conference organizers (most regional events have a responsible disclosure policy).
- Step 2: Run the above passive scans only. Do NOT inject packets.
- Step 3: If you discover a rogue AP (e.g., same SSID as official Wi-Fi but different MAC), report it immediately to the event’s security desk.
- Step 4: Use this as a conversation starter: “I found this while testing my collision agenda – want to see how I did it?”
4. Post-Conference Automation – Turning Handshakes into Hardening
Copeland’s “3 ideas to bring back” often die in notebook limbo. Automate the ingestion and actioning of those ideas using Linux systemd timers or Windows Task Scheduler.
Linux – Auto-extract business cards and generate follow-up tickets:
Install OCR and Jira CLI
sudo apt-get install ocrad jira-cli -y
Watch a directory for scanned business card images
inotifywait -m ~/scans/ -e create -e moved_to |
while read path action file; do
ocrad "$path/$file" > card_text.txt
Parse email and create Jira ticket
grep -E -o "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+.[A-Z|a-z]{2,}\b" card_text.txt > email.txt
jira-cli create --type "Task" --summary "Follow up from BSidesNOLA" --description "$(cat card_text.txt)"
done
Windows PowerShell automation:
Use Watch-Folder to trigger Microsoft To-Do or email draft
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "$env:USERPROFILE\OneDrive\ConferenceScans"
$watcher.Filter = ".png"
$watcher.EnableRaisingEvents = $true
$action = {
$text = (Get-Date).ToString() + " - New scan: " + $Event.SourceEventArgs.FullPath
Add-Content -Path "$env:USERPROFILE\collision_followups.txt" -Value $text
Start-Process "mailto:[email protected]?subject=BSides%20Lead&body=Check%20$($Event.SourceEventArgs.Name)"
}
Register-ObjectEvent $watcher "Created" -Action $action
What this does: Every business card or handwritten whiteboard photo becomes an automated Jira ticket or email draft, ensuring that the “collision agenda” yields measurable output—a decision the business can make.
5. Cloud Hardening from a Vendor Hall Conversation
Imagine a startup says they “automate CSPM across AWS and Azure.” Instead of trusting the demo, run a live minimal permission check from your laptop.
AWS CLI (pre‑configured with read‑only role):
aws iam generate-credential-report
aws iam get-credential-report --query 'Content' --output text | base64 -d > iam_report.csv
Check for unused keys over 90 days
awk -F',' '$8 > 90 {print $1}' iam_report.csv
Azure PowerShell:
Connect-AzAccount -UseDeviceAuthentication
Get-AzRoleAssignment | Export-Csv -Path "azure_assignments.csv"
Find overprivileged service principals
Get-AzADServicePrincipal -All | ForEach-Object {
$roles = Get-AzRoleAssignment -ObjectId $<em>.Id
if ($roles.Count -gt 5) { Write-Warning "$($</em>.DisplayName) has $($roles.Count) roles" }
}
Integration with conference value: Show the startup founder that you already know their space. “Your tool would have caught this unused key in our AWS – let’s discuss a pilot.” This shifts the dynamic from buyer-seller to peer validation.
What Undercode Say:
- The “unexpected value” Copeland champions is not luck—it is a product of deliberate preparation and technical agility. You cannot exploit hallway collisions without a portable toolkit.
- Regional conferences expose different attack surfaces (less corporate filtering, more open Wi-Fi) and different people (founders with skin in the game). Both are hard to find in webinars or dashboards.
- By merging social engineering (starting conversations) with real-time scripting (validating technical claims on the spot), you turn soft skills into hardened intelligence.
- The Linux/Windows commands above are not just for conference play; they form a repeatable methodology for any unstructured security assessment – from a meetup to an incident response cold site.
Prediction:
As AI-generated content floods mainstream cybersecurity feeds, the value of in-person, unscripted collisions will skyrocket. Expect a rise in “anti-conference” formats – unconferences, lockpicking villages, and blue-team capture the flag events where the agenda is empty by design. The professionals who thrive will treat regional events as live-fire training grounds, deploying the same automation and threat hunting skills they use in production to extract maximum ROI from every handshake and every rogue AP they discover. LinkedIn will eventually launch a “collision score” metric – but the real winners will be those who, like Copeland, leave talking about the openers.
