Introduction:
In a digital era where self-proclaimed “experts” without formal credentials actively “activate” in fields as sensitive as psychology and medicine, cybersecurity faces the same dangerous trend—unqualified individuals offering critical security advice, penetration testing, or incident response without validated knowledge. Just as a person without a medical degree cannot perform maxillofacial surgery, an uncertified practitioner without hands-on forensic training cannot secure your enterprise network, leaving organizations vulnerable to breaches that fake experts fail to prevent or even detect.
Learning Objectives:
- Identify and mitigate risks posed by unverified IT and cybersecurity practitioners in your organization.
- Implement credential-verification protocols and technical assessments to filter genuine experts from impostors.
- Apply Linux/Windows hardening commands and API security measures that only trained professionals should execute.
You Should Know:
- Credential Validation & Technical Screening for Cybersecurity Hires
The LinkedIn discussion highlights a societal problem: people “activating” in a field without diplomas. In cybersecurity, this translates to candidates claiming CEH, OSCP, or CISSP without proof, or using dump-based certifications. Implement a technical screening lab before granting any access.
Step‑by‑step guide to verify a candidate’s practical skills:
For Linux (assess live system knowledge):
Request the candidate to explain and execute (in a sandbox): 1. Check for listening ports and identify suspicious services sudo ss -tulpn | grep LISTEN <ol> <li>Verify integrity of system binaries (Tripwire/AIDE alternative) sudo aide --check</p></li> <li><p>Extract hidden processes using unhide sudo unhide proc</p></li> <li><p>Simulate a forensic memory capture sudo avml capture memory.dump
For Windows (PowerShell validation):
Check for unauthorized scheduled tasks
Get-ScheduledTask | Where-Object {$_.State -ne "Disabled"}
List all users with admin privileges
Get-LocalGroupMember -Group "Administrators"
Verify running processes against known malware hashes (using local threat DB)
Get-Process | ForEach-Object { Get-FileHash -Path $_.Path -Algorithm SHA256 }
How to use this:
Set up an isolated VM with a known misconfiguration or a hidden reverse shell. Ask the candidate to identify the issue, document findings, and remediate within 30 minutes. Record their terminal session. Genuine experts will use the above commands naturally; impostors will rely on GUI tools or generic advice.
2. Hardening Cloud APIs Against Unqualified Configuration
Many self-taught “cloud security experts” misconfigure APIs, leading to data leaks. The same arrogance seen in pseudo-psychologists appears in IT when someone reads a blog and thinks they understand IAM policies.
Step‑by‑step guide to audit and harden API security (vendor-agnostic commands):
Check for overly permissive CORS (using curl):
curl -X OPTIONS https://api.yourdomain.com/v1/data -H "Origin: https://evil.com" -H "Access-Control-Request-Method: GET" -v Look for Access-Control-Allow-Origin: in response
Scan for exposed secrets in Git repos (using truffleHog):
docker run -it -v "$PWD:/pwd" trufflesecurity/trufflehog filesystem /pwd --only-verified
Enforce least privilege on AWS S3 (AWS CLI):
List buckets with public ACLs aws s3api get-bucket-acl --bucket your-bucket --query 'Grants[?Grantee.URI==`http://acs.amazonaws.com/groups/global/AllUsers`]' Apply bucket policy to deny unencrypted uploads aws s3api put-bucket-policy --bucket your-bucket --policy file://deny-plaintext.json
How to use this:
Run these commands monthly as part of a “cloud hygiene” routine. If any tool returns unexpected results, escalate to a verified cloud architect. Do not let an uncertified junior interpret these outputs—misreading an IAM policy can open an entire data lake.
3. Vulnerability Exploitation & Mitigation: The Practical Test
A person who “activates” in pentesting without structured training (like eJPT, OSCP, or GPEN) will miss critical vulnerabilities or, worse, crash production systems. Use this controlled lab exercise to separate real analysts from impostors.
Step‑by‑step guide to exploit a fake SQLi (for training only on your own environment):
Set up a vulnerable container (using Docker):
docker run -d -p 8080:80 --name sqli-lab vulnerables/web-dvwa
Attempt time-based blind SQL injection (manual command):
For a search parameter curl "http://localhost:8080/vulnerabilities/sqli/?id=1' AND SLEEP(5)--&Submit=Submit" --cookie "security=low; PHPSESSID=your_session" Measure response time; if >5 seconds, injection works
Mitigation using parameterized queries (Python example for Windows/Linux):
import sqlite3
conn = sqlite3.connect('secure.db')
cursor = conn.cursor()
Safe query – no concatenation
cursor.execute("SELECT FROM users WHERE id = ?", (user_id,))
How to use this:
Build this lab during an interview. Ask the candidate to exploit the vulnerability (in a safe manner) and then fix the code. A genuine expert will not only run sqlmap but also explain the WAF bypass techniques and prepared statements. An impostor will claim “this is outdated” without providing a working exploit or patch.
- Linux Forensics: Detecting Post-Break Activity by Unqualified “Investigators”
When a breach occurs, many self-declared forensicators run random commands and destroy evidence. Follow this validated chain-of-custody procedure.
Step‑by‑step guide for live system forensics (must be done by trained personnel only):
Preserve volatile data first:
Capture memory (using LiME or fmem) sudo insmod lime.ko "path=/tmp/mem.lime format=lime" Record network connections sudo netstat -anp > netstat_$(date +%Y%m%d_%H%M%S).txt List all processes with full details ps auxwf > ps_$(date +%Y%m%d_%H%M%S).txt
Acquire disk image (using dd over netcat to avoid local writes):
On forensic workstation nc -l -p 9000 | dd of=/cases/evidence.dd On compromised host (read-only mount) sudo dd if=/dev/sda bs=4M | nc <forensics_ip> 9000
How to use this:
Never run these commands on a live production server unless you have explicit approval and proper training. After acquisition, compute hashes (sha256sum evidence.dd) and store them immutable. Impostors often skip hashing, making evidence inadmissible.
5. Windows Active Directory Hardening Against Privilege Escalation
Unqualified IT staff often leave AD misconfigured, allowing Kerberoasting or pass‑the‑hash attacks. This section mimics the “I active in psychology” attitude – “I active in domain security.”
Step‑by‑step guide to audit and lock down AD (run as Domain Admin in a test environment):
Enumerate SPNs and check for weak encryption (PowerShell):
Find all Kerberoastable accounts (RC4_HMAC enabled)
Get-ADUser -Filter {ServicePrincipalName -ne "$null"} -Properties ServicePrincipalName,msDS-SupportedEncryptionTypes | Where-Object {$_.msDS-SupportedEncryptionTypes -notcontains 24}
Disable RC4 for critical accounts
Set-ADUser -Identity vulnerable_svc -Replace @{'msDS-SupportedEncryptionTypes'=24}
Detect pass‑the‑hash attempts using Sysmon (install first):
Install Sysmon with known-good config
.\Sysmon64.exe -accepteula -i sysmonconfig.xml
Look for Event ID 4624 with Logon Type 3 and certain authentication packages
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4624} | Where-Object {$<em>.Properties[bash].Value -eq '3' -and $</em>.Message -like 'NTLM'}
How to use this:
Run the SPN enumeration weekly. If you find accounts with RC4 enabled that are not legacy systems, escalate immediately. Impostors will say “Kerberoasting is overrated” but cannot explain why modern attackers still use it to compromise 30% of enterprises.
- Training Courses to Separate Real Experts from Impostors
Based on the post’s theme, formal education and validated certifications matter. Here are specific, vendor-neutral training paths that prove competence—unlike “I active in AI” claims.
Recommended free and paid resources (URLs extracted from context / added for actionability):
– Cybersecurity fundamentals: tryhackme.com (Blue team paths) – verify completion via badges
– Linux forensics: https://www.sans.org/cyber-security-courses/advanced-incident-response-threat-hunting-training/ (FOR508)
– Offensive security validation: OSCP from offensive-security.com (practical exam, no multiple choice)
– Cloud hardening: https://cloudsecurityalliance.org/education/ccsk
– Windows AD defense: Certified Red Team Operator (CRTO) from zeropointsecurity.co.uk
Step‑by‑step guide to build a continuous learning lab:
- Install Proxmox or VMware ESXi free version on a spare server.
- Deploy Security Onion (for network monitoring) and a vulnerable Windows domain (using AutomatedLab).
- Every week, pick one TTP from MITRE ATT&CK (e.g., T1558 – Kerberoasting) and simulate it using tools like Rubeus or Impacket.
- Document detection rules (Sigma or YARA) and share them with your team.
What Undercode Say:
- Credentials are not everything, but absence of validated practical exams is a red flag. The Romanian podcast incident mirrors IT: without a structured, proctored assessment (like OSCP or GPEN), anyone can claim expertise.
- Society’s tolerance for “activating” in complex fields creates real security debt. Every unqualified “pentester” who misses a SQL injection or misconfigures a firewall is the digital equivalent of a fake psychologist causing harm.
- Automated verification scripts (like the ones above) must become HR’s first filter before any security hire touches production. A 30-minute live lab reveals more than ten interviews.
The LinkedIn thread’s outrage about pseudo-experts is a wake‑up call for cybersecurity leaders. We cannot rely on self‑proclaimed “multi‑talented innovators” without forensic certifications or 58 unrelated badges. Implement technical screening, enforce continuing education with hands‑on exams, and treat every “I active in IT” claim with the same skepticism as a non‑surgeon offering maxillofacial procedures.
Prediction:
Within 18 months, regulatory bodies (e.g., EU Cyber Resilience Act) will mandate practical, proctored exams for anyone handling critical infrastructure security—just as medical boards require residencies. Unqualified “influencer” cybersecurity experts will face legal liability for damages caused by their advice. Companies that fail to vet practitioners using live technical assessments will suffer breaches that could have been prevented by a single proper credential check. The pendulum will swing hard away from self‑declared expertise toward verifiable, continuous, and practical validation.
