27. Social Engineering Awareness
27.6 Red vs Blue, Project and Real Incidents
Chala mitrano, phishing, vishing, smishing, pretexting, SET awareness, 1930 – aata Purple Team loop. Red authorised training lab madhe lookalike URL / mock mailbox dakhavto (kadhihi strangers la nahi); Blue URL+HTTPS check, OTP never share, callback on official number, MFA, email filters/DMARC awareness ani staff safety card lavto. Tumhi Raja-Rani Traders style OWN consented simulation madhe build → hack → fix karun Purple report liha. Awareness; fix + prove = career. Samjla ka? Real people without written consent – kadhi nahi.
Red Team vs Blue Team – social engineering awareness
| Red team (attacker) does | Blue team (defender) detects / stops |
|---|---|
| Phishing / spear phishing email with lookalike URL (concept) | Teach URL bar + HTTPS lock check; never click-to-login – open official app/site |
| Vishing / smishing: urgency + "share OTP" | Never share OTP/password/PIN; callback on number from official site/app |
| Pretexting as bank / manager / IT support | Verify unusual requests out-of-band; written approval for money/access changes |
| Baiting (USB labelled "salary") / tailgating | No unknown USBs; badge/door discipline; report left media to IT |
| SET-style fake login page in authorised awareness lab only | Security awareness training + simulated phishing only with written consent |
| Typosquat / lookalike domain for brand | MFA everywhere; SPF/DKIM/DMARC high-level for your domain; report to 1930 / cybercrime.gov.in |
Defender chi simple checklist: URL+HTTPS → never OTP → official callback → MFA → report 1930/cybercrime.gov.in → awareness training → DMARC/SPF if you own a domain → prove staff can spot a lookalike. SET = awareness tool authorised lab madhe; bachav habits + MFA + reporting Blue var. Interview madhe "I phished people" peksha "I ran a consented simulation, showed the lookalike URL, then rolled out a safety card, MFA and a clear report path" jast strong.
# OWN / consented lab only – NEVER send phishing to strangers
mkdir -p ~/labs/raja-rani-se
# Safe mock (examples – pick what you control):
# 1) Closed lab mailbox / mailhog / local SMTP catcher on YOUR VM
# 2) HTML lookalike login page served only on host-only (e.g. 192.168.56.50) – not on the internet
# 3) Written consent list (classmates who signed) before any simulation inbox send
# Document the lookalike (do not use real customer emails):
echo 'Example lookalike (training): https://paypa1-secure.example.lab/login' \
> ~/labs/raja-rani-se/lookalike-note.txt
echo 'Real habit: type paypal.com yourself; check HTTPS lock; never OTP on phone' \
>> ~/labs/raja-rani-se/lookalike-note.txt
# Blue prove checklist (write answers in the same folder):
# - Staff safety card: 5 rules + 1930 + cybercrime.gov.in
# - MFA enabled on mail + bank apps used for the shop
# - If Raja-Rani has a domain: ask admin about SPF/DKIM/DMARC status (high-level – no need to break DNS)
# - Report path: who to tell in shop + national helpline
Ravindra Bagale's Tip
Students SET ne "friend la surprise test" pathavtat – consent nahi, IT Act todla. Dusri chuk: OTP "ekda okay" mhanun share. Rule: written consent OR closed mock mailbox only → show lookalike URL → FIX with safety card + MFA + report path same day → never real phishing to strangers. Social engineering chapter = human firewall chapter. Ghabru naka, habit ne yetay.

SET concept notes (27.4) warpashi bagha – pan tool strangers var naka. Swatahcha host-only mock page OR closed lab mailbox madhe ek lookalike URL example banva (fictional brand). Screenshot/notes ~/labs/raja-rani-se/: URL bar farak, HTTPS habit, "never OTP", callback rule. Mag 1-page family/staff safety card (1930 + cybercrime.gov.in) liha.

Project: Build it, hack it, fix it
Build: For fictional Raja-Rani Traders (Nashik/Pune shop staff awareness) on systems you own or classmates with written consent:
- Ethics card + consent list (or use only a mock mailbox / host-only fake page – no strangers)
- Draft one training email theme (delivery update / password reset) – fictional brand, not a real customer's bank
- Prepare the safety card template (5 rules + 1930 + cybercrime.gov.in)
Hack (lab awareness only – OWN / consented):
- Show how convincing a lookalike URL/page looks (SET awareness or static HTML on host-only
.50) - If using email simulation: send only to accounts you own or classmates who consented in writing (or a closed lab catcher)
- Record who clicked in the safe simulation (training metric) – no shame, only learning
Do not phish strangers, do not collect real OTPs/passwords, do not host fake bank pages on the public internet, do not call random people as "bank fraud test".
Fix:
- Hand out the safety card; run a short awareness huddle (URL check, never OTP, official callback)
- Enable MFA on shop mail and critical apps Raja/Rani control
- Document report path: shop owner + 1930 + cybercrime.gov.in
- If they have a domain: high-level note on SPF/DKIM/DMARC with their DNS admin (awareness, not a full mail-server rebuild)
Re-verify: Second mini-quiz or consented resend – click rate drops; MFA screenshots; safety card signed/acknowledged. 1-page Purple report for owners Raja and Rani: finding → risk → training/MFA/DMARC/report fix → evidence. Peer-review with Zoya / Salman. IT Act 66C/66D: no real-world fraud simulations without authorisation.
Real incident: Twitter / X employee social engineering – bitcoin scam (2020)
In July 2020, public reporting described a breach of Twitter (now X) in which attackers used social engineering against employees to gain access to internal tools, then posted bitcoin-scam messages from many verified high-profile accounts. Users were urged to send cryptocurrency to addresses controlled by the attackers; platforms and law enforcement publicly discussed the employee-targeted social engineering angle. Weakness: trusted internal tools reachable after staff were manipulated, plus the viral reach of verified accounts. What would have reduced it: stronger employee verification for sensitive tools, least privilege on admin panels, MFA and phishing-resistant authentication for staff, and rapid internal alerting when verified accounts mass-post identical scam text. Lab lesson: your Raja-Rani project is not "email filters only" – staff awareness + MFA + privileged-tool access control matter as much as spam rules.

Real incident: Target – HVAC vendor phishing path (2013)
In 2013, the Target retail breach was widely reported as involving credentials tied to an HVAC vendor whose access was used as a path into Target's network; public reporting linked the vendor compromise to phishing-style attacks against that third party. Payment-card data exposure was reported at very large scale (exact figures vary by source – treat published numbers as reported, not as your invention). Weakness: third-party vendor access without enough segmentation and vendor security hygiene, so one phished partner became a bridge. What would have reduced it: vendor risk reviews, network segmentation so HVAC/vendor networks cannot reach cardholder systems, MFA on vendor VPN/accounts, and phishing-resistant awareness for suppliers. Lab lesson: social engineering often hits the weakest connected human – Blue must harden staff and vendors.

Interview model (clean English): "I only run phishing simulations on accounts I own or classmates who consented in writing. I show how a lookalike URL fools people, then I fix it with a staff safety card, MFA, a clear 1930 report path, and high-level SPF/DKIM/DMARC awareness for the shop domain."
Thodkyaat: fasavnuk olakha, pan MFA + safety card + 1930 shika. Aata pudhe digital forensics – purava. Chala pudhe, mitrano!
Thodkyaat sangaycha tar
- Social engineering attacks people, not machines, using authority, urgency, greed, trust and curiosity.
- Types: phishing (email), spear phishing, vishing (call), smishing (SMS), pretexting, baiting (USB), tailgating.
- Spot phishing with the 8-point checklist; the strongest habit is never clicking a link to log in – open the site yourself.
- SET shows how convincing fakes are made; it is for authorised awareness training only, never for attacking real people.
- No legitimate bank or company ever asks for your OTP/password/PIN.
- If tricked: disconnect, change passwords from a safe device, enable MFA, call the bank, and report to 1930 / cybercrime.gov.in.
