AI vs AI: Winning the Cybersecurity Battle Against Deepfake Scams

Cybercrime is evolving—and it’s weaponising trust.

Phishing attacks in BFSI surged by 60% in 2024, and cyber criminals now use AI-powered deepfakes to bypass even the most sophisticated security systems.

Imagine this:

In 2024, a deepfake video of Indian Government Officials and renowned business personalities was circulated, falsely promising government-backed financial schemes. The voice, the facial expressions, everything looks real. The official confidently urges the approval of a “special investment fund” or an “exclusive banking service.” But here’s the catch—it’s not real.

A central multinational bank had $35M stolen after an employee was tricked by a deepfake CEO’s voice ordering a fraudulent transfer.

AI-Driven Scams: What You Need to Watch For

?

A.??? Enhanced Email Phishing AI allows scammers to craft flawless phishing emails—mimicking the tone, writing style, and even email formatting of CEOs, government officials, and financial institutions. Warning Sign: Unusual urgency, links leading to unknown domains, or minor email address discrepancies.

B.???? Voice Spoofing & Cloning AI can duplicate a person’s voice—turning a recorded sample into a fake phone call or chatbot conversation. Warning Sign: Unexpected calls from familiar voices asking for urgent financial transactions or sensitive information.

C.???? Deepfake Manipulation AI-generated videos now perfectly replicate faces and voices, making it appear as if renowned figures or even someone you know is making a request. Warning Sign: Subtle lip-syncing, facial expressions, or lighting inconsistencies.

Here’s a quick guide to AI-powered cyber threats, how they operate, and the best strategies to counter them in BFSI."

How to Spot & Stop AI-Powered Scams

Detecting Deepfakes:

1.????? Lip Sync Issues: Audio may not match mouth movements perfectly. Watch for unusual pauses, unnatural blinking, or robotic tone shifts.

2.????? Odd Lighting & Shadows: Teeth, jewellery, or hair may flicker unnaturally, and lighting may seem inconsistent with the surroundings.

3.????? Facial Anomalies: Misplaced features, disappearing glasses, or blurred edges around the face are telltale signs of AI tampering.

?Are traditional cybersecurity strategies prepared for these evolving threats?

The BFSI sector rapidly increases its cybersecurity investments in response to AI-driven threats. Global spending on cybersecurity is expected to reach $212 billion by 2025, reflecting a 15.1% increase from 2024. This surge highlights the urgency of adopting next-generation security strategies.

The Real Battle: Technology vs. Psychology

The BFSI sector, managing trillions of dollars in daily transactions, has fortified its defences with firewalls, AI-powered fraud detection, and multi-factor authentication (MFA).

Yet, cybercriminals no longer exploit systems—they exploit human psychology.

How??

Exploiting Human Psychology

?a)????? Authority Bias – Employees instinctively trust directives from perceived leaders.

b)????? Emotional Triggers – Fear, urgency, and empathy are weaponised to force quick, irrational decisions.

c)????? Cognitive Tunnelling – Victims hyper-focus on an immediate task, missing the warning signs of deception.

A firewall won’t stop an employee from believing a deepfake government official. MFA won’t prevent a deepfake CEO from ordering a fund transfer.

“Here’s a real-world example of how even sophisticated BFSI institutions can fall prey to AI-powered social engineering scams.”

How Human Psychology Led to a $35M Deepfake Scam in BFSI– A Costly Mistake in BFSI

In 2024, a multinational bank with operations across Asia and Europe fell victim to an AI-powered deepfake attack, resulting in a staggering $35 million fraudulent transfer.

How It Happened:

1. Deepfake CEO Call – A mid-level finance executive received a video call from what appeared to be the CEO of the bank’s European division. The deepfake was astonishingly realistic, with natural facial expressions, accurate voice tone, and real-time lip-syncing.
2. Authority Bias & Urgency Manipulation – The "CEO" urgently requested the immediate approval of several large fund transfers to “facilitate a high-priority acquisition.” The attacker exploited the executive’s instinctive trust in leadership directives. They created a false sense of urgency, stating that regulatory approvals were time-sensitive.
3. Cognitive Tunneling in Action—Overwhelmed by the apparent authority and urgency, the executive failed to follow standard verification protocols. He authorised the transfers without cross-checking with other internal teams.
4. Delayed Fraud Detection – The fraud was discovered only after internal auditors flagged irregularities. When forensic analysis confirmed the deepfake attack, the stolen funds had been routed through multiple offshore accounts, making recovery almost impossible.

?

Key Takeaways for BFSI:

a)????? AI-powered cyber fraud is not just about technology—it manipulates human psychology.

b)????? Standard cybersecurity measures (MFA, firewalls) are ineffective against psychological deception.

c)????? Mandatory multi-person authentication for large transactions is critical.

d)????? Real-time deepfake detection tools should be integrated into high-stakes financial decision workflows.

e)????? Employee training must include behavioural cybersecurity awareness—focusing on how attackers manipulate trust and urgency.

?So, what’s the solution?

?Cybersecurity 2.0: Strengthening Cognitive Resilience

To combat these evolving threats, BFSI leaders must go beyond technology and focus on the human element of cybersecurity. Cognitive resilience is the missing piece in today’s cyber defence strategy.

Key steps to enhance security in BFSI:

1.????? Implement AI-Powered Deepfake Detection – Advanced AI tools must scan for manipulated audio and video signals.

2.????? Train Employees to pause, verify, and challenge unexpected requests – Verification is necessary even if a directive appears to come from a high-profile figure.

3.????? Align cybersecurity efforts across IT, finance, and compliance teams.

4.????? Deploy blockchain and AI-driven anomaly detection.

5.????? Gamify Cybersecurity Training – Employees must learn through realistic phishing & deepfake simulations that mimic real-world scams.

6.????? Zero-Trust Security – Multi-layer authentication required.

7.????? Real-Time AI Monitoring – Detect fraud before execution.

Educate Your Customers: BFSI organisations should educate their customers

Before Acting, Follow a 3-Step Rule:

STOP Pause. Scammers thrive on urgency. Never share PINs, passwords, verification codes, or personal credentials.

CHALLENGE Ask yourself: Could this be fake? Don’t be afraid to reject, ignore, or verify requests. Call the organisation directly using their publicly listed contact details. If someone is rushing you, that’s a red flag.

PROTECT Consult a trusted person before making any financial decisions. Double-check all requests before transferring funds.
