Introduction:
Curated resource lists are goldmines for cybersecurity and IT professionals, yet most overlook the power of a well-organized start page. The post from Harun Seker (CISSP, CEH, CSIS, CIOS) highlights 50 everyday websites spanning productivity, writing, design, file tools, travel, security, and learning – all aggregated into a single Start.me page. For defenders, analysts, and red teamers, this collection is more than convenience; it’s a tactical arsenal for threat intelligence, continuous learning, and tool integration.
Learning Objectives:
- Discover and operationalize a curated Start.me page of 50 websites relevant to cybersecurity, IT, and AI workflows.
- Implement hands-on techniques for bookmark management, SOCRadar threat intelligence queries, and API security checks.
- Apply Linux/Windows commands and cloud hardening steps derived from the resources in the collection.
You Should Know:
1. Extracting and Automating Bookmarked Security Feeds
The Start.me page (https://lnkd.in/e2782xe8) likely aggregates RSS feeds, security blogs, and real-time threat dashboards. Instead of manually visiting each site, automate the extraction of URLs and feed monitoring using command-line tools.
Step‑by‑step guide (Linux/macOS):
- Use `curl` to fetch the Start.me page source (replace with actual resolved URL after expanding the LinkedIn shortlink):
curl -s https://start.me/p/example | grep -Eo 'https?://[^"]+' > bookmarks.txt
- Filter security‑relevant domains:
grep -E 'security|threat|cyber|cve|vulnerability' bookmarks.txt > security_feeds.txt
- Monitor RSS feeds using `rsstail` (install via
apt install rsstail):rsstail -i 600 -u https://example-security-blog.com/feed
Windows (PowerShell):
Invoke-WebRequest -Uri "https://start.me/p/example" | Select-Object -ExpandProperty Links | Where-Object {$_.href -match "security|cyber"} | Export-Csv -Path security_links.csv
What it does: Converts a static bookmark collection into a dynamic, monitorable feed. Use cron or Task Scheduler to run hourly, alerting on new CVE mentions or IoCs.
2. SOCRadar Integration for External Threat Intelligence
Innocent Akpareva recommended adding SOCRadar – a threat intelligence platform offering attack surface management, dark web monitoring, and free modules. Here’s how to integrate SOCRadar queries into your bookmark workflow.
Step‑by‑step guide:
- Create a free SOCRadar account (SOCRadar.io). Obtain your API key from the dashboard.
- Use `curl` to check your organization’s exposed assets:
curl -X GET "https://api.socradar.io/api/v1/company/asset?apikey=YOUR_API_KEY" -H "Content-Type: application/json"
- Automate daily checks via script:
!/bin/bash API_KEY="your_key" curl -s "https://api.socradar.io/api/v1/threat/hash?apikey=$API_KEY&hash=example_md5" | jq '.'
- For Windows PowerShell:
$headers = @{ "apikey" = "YOUR_API_KEY" } Invoke-RestMethod -Uri "https://api.socradar.io/api/v1/company/asset" -Headers $headersHardening tip: Store API keys in environment variables or a vault (e.g.,
export SOCRADAR_KEY=...), never hardcode. Rotate keys quarterly.
- Linux/Windows Commands for Live Incident Response from Learning Sites
The collection includes “learning” websites. Among them are likely cyber ranges and hands-on labs. Use these commands to practice incident response on your own machine.
Linux memory and process analysis:
List all listening ports with process IDs sudo netstat -tulpn Capture running processes and hash them for integrity ps aux --sort=-%cpu | head -20 > top_procs.txt sha256sum /proc//exe 2>/dev/null > proc_hashes.txt Check for unexpected cron jobs crontab -l; sudo cat /etc/crontab
Windows (CMD/PowerShell):
netstat -anob > open_conn.txt tasklist /v /fo csv > tasks.csv schtasks /query /fo LIST /v > scheduled_tasks.txt
Tutorial: Use the bookmarked “File Tools” sites (e.g., VirusTotal uploader, CyberChef) to decode suspicious base64 payloads found in logs. For example, decode with CyberChef’s CLI alternative:
echo "SGFjayBUaGUgUGxhbmV0" | base64 -d
- API Security Hardening from Productivity & Design Tools
Many bookmarked websites (e.g., API testing tools, password managers, collaboration platforms) expose APIs. Apply these API security hardening steps from the “Security” and “Design” categories.
Step‑by‑step guide:
- Identify API endpoints used by bookmarked tools via browser developer tools (F12 → Network tab).
- Enforce rate limiting at the reverse proxy (example for Nginx):
limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s; location /api/ { limit_req zone=api burst=20 nodelay; } - Validate JWT tokens properly: never trust
alg: none. Use command line to check token:echo "YOUR_JWT" | cut -d"." -f2 | base64 -d | jq .
- For Windows, use `jq` in WSL or PowerShell’s
ConvertFrom-Json. - Remediate broken object level authorization (BOLA) by implementing resource‑level checks in code.
- Cloud Hardening Using Resources from the Travel & File Tools Categories
Travel websites often include VPN reviews and secure file transfer services. Combine these with file encryption tools to harden cloud storage.
Step‑by‑step guide (AWS S3 example):
- List all S3 buckets and enforce block public access:
aws s3api list-buckets --query "Buckets[].Name" --output text | xargs -I {} aws s3api get-public-access-block --bucket {} --no-cli-pager - Encrypt files locally before upload using
gpg:gpg --symmetric --cipher-algo AES256 sensitive.docx aws s3 cp sensitive.docx.gpg s3://your-secure-bucket/
- Windows: use `gpg4win` or `7z a -pPASSWORD -mx=9 archive.7z files` then upload via AWS CLI for PowerShell.
- Enable bucket versioning and MFA delete:
aws s3api put-bucket-versioning --bucket my-bucket --versioning-configuration Status=Enabled,MFADelete=Enabled
- Vulnerability Exploitation/Mitigation Practice via “Writing” and “Learning” Sites
The writing tools may include markdown editors that inadvertently allow XSS; the learning sites likely host vulnerable web apps (e.g., DVWA, WebGoat). Use the bookmarks to train on OWASP Top 10.
Step‑by‑step guide – XSS exploitation and mitigation:
- Deploy a local vulnerable app from one of the bookmarked learning platforms (e.g.,
docker pull vulnerables/web-dvwa). - Inject a test payload: `` into a comment field.
- Mitigate by setting Content Security Policy (CSP) headers. On Apache:
Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
- For Windows IIS, use URL Rewrite module.
- Validate CSP with command line:
curl -I https://your-lab-site.com | grep -i content-security-policy
- Automate scanning of bookmark URLs for XSS using
dalfox:dalfox url https://target.com --deep
What Undercode Say:
- Key Takeaway 1: A single Start.me page can act as a force multiplier for cybersecurity professionals, but only if you actively script and automate interactions with its resources rather than passively bookmarking.
- Key Takeaway 2: SOCRadar’s free API and threat intelligence feeds are underutilized – integrating them into daily `cron` jobs or PowerShell scripts transforms passive reading into proactive defense.
Analysis (approx. 10 lines):
The original post highlights 50 everyday websites, yet most users will never leverage them beyond manual browsing. By treating the bookmark list as an attack surface or a data source, defenders can automate threat feed ingestion, API health checks, and cloud misconfiguration detection. The mention of SOCRadar by Innocent Akpareva is critical – SOCRadar’s attack surface management correlates with the “Security” category of the Start.me page, providing external telemetry that internal tools miss. Moreover, the integration of Linux/Windows commands into daily workflows (like `netstat` and `ps` for IR) bridges the gap between knowing resources and acting on them. The training courses implied by Harun Seker’s certifications (CEH, Pentest+, CASP+) suggest that the “learning” websites likely include free labs and exam prep – perfect for hands-on exploitation practice. Without automation and scripting, these 50 websites become digital clutter; with them, they become a personalized SOAR (Security Orchestration, Automation, and Response) platform.
Prediction:
As curated link aggregators like Start.me become more common among SOC teams, we will see a rise in “bookmark-based threat intelligence” – where analysts share live dashboards of monitored CVE feeds, IoC lists, and deception technology links. Attackers will begin targeting these public collections to poison bookmarked URLs (e.g., typosquatting, dead‑link hijacking), forcing the need for cryptographic verification of resource integrity. Within two years, expect automated tools that scan shared bookmark pages for outdated or malicious links, and cloud-based bookmarking services will add native security scoring for each saved URL – turning the simple act of bookmarking into a continuous trust assessment pipeline.
