Top 23 Cybersecurity Vulnerabilities in Pakistani Banking Systems That Hackers Exploit

Cybersecurity vulnerabilities in Pakistani banking systems are a ticking time bomb. Hackers, fraudsters, and even rogue employees exploit weak banking security, outdated software, and poor regulations to steal millions from Pakistani banks.

In 2022, hackers breached BankIslami Pakistan, stealing $6 million through fraudulent SWIFT transactions.Similarly, in 2023, Meezan Bank faced multiple phishing attacks, where fake SMS messages tricked thousands of customers into sharing banking details.

IdealSolutions has reported  23 major vulnerabilities that threaten Pakistani banks, mobile banking apps, ATMs, and online transactions.

How Do Hackers Target Pakistani Banks?

Hackers exploit technical flaws, human errors, and weak regulations to compromise banking security. Here’s how:

✔️ ATM Skimming: Fraudsters install skimmers on MCB and HBL ATMs to steal card data.
✔️ Fake Mobile Banking Apps: Cybercriminals create fake JazzCash and Easypaisa apps to steal login credentials.
✔️ Insider Leaks: Bank employees sell customer data on the dark web.
✔️ SIM Swap Fraud: Hackers clone SIM cards to intercept OTPs and steal money.
✔️ SWIFT Transaction Fraud: BankIslami suffered a SWIFT hack, losing $6 million.

Pakistani Banking Core System & Cybersecurity Vulnerabilities

1. Unsecured APIs in Pakistani Banking Apps

Pakistani banks rely on APIs for transactions, but many lack encryption. Hackers intercept API calls to steal account details.

✔️ Example: A hacker exploited a weak UBL mobile banking API to access customer balances.

2. Outdated Core Banking Software (CBS) Used by Pakistani Banks

Many banks in Pakistan use 10+ year-old CBS platforms (like T24, Finacle, and Oracle FLEXCUBE), which have unpatched security flaws.

✔️ Example: An outdated CBS in a local microfinance bank led to a data breach in 2022.

3. Weak ATM Security & Hardcoded PINs

Many ATMs in Pakistan run on outdated Windows XP, allowing hackers to execute remote commands.

✔️ Example: In 2023, a group hacked an HBL ATM in Lahore using a USB exploit.

4. No End-to-End Encryption for Online Banking

Many Pakistani banking websites still use weak TLS 1.0/1.1 encryption, making them vulnerable to man-in-the-middle attacks.

✔️ Example: A Karachi-based hacker exploited weak encryption on an Islamic bank’s online portal to intercept login details.

Example:

• 2022: A senior executive at a Karachi-based bank was targeted, leading to an internal network compromise.

6. Insider Data Theft:

Employees Selling Customer Data on Dark WebBank employees leak customer data, credit card details, and account credentials for financial gain.

Notable Cases:

• 2021: An insider from a Pakistani private bank was caught selling 100,000+ customer records on dark web forums.

ATM & Transaction-Based Vulnerabilities in Pakistani Banks

7. ATM Skimming Attacks in Major Cities

Fraudsters install card skimmers on ATMs in Karachi, Lahore, and Islamabad to steal card data.

✔️ Example: In 2023, a skimming attack on Askari Bank ATMs led to PKR 40 million in losses.

8. POS Machine Hacking in Pakistani Retail Stores

Hackers infect POS terminals in supermarkets to steal customer card details.

✔️ Example: Hackers compromised POS terminals at a famous Lahore mall, stealing 20,000 credit card details.

9. QR Code Scams: Fake QR Codes at ATMs & POS Machines

Cybercriminals are placing malicious QR codes at ATMs and point-of-sale (POS) machines to redirect users to fraudulent payment portals.

Notable Cases in Pakistan:

• Karachi (2023): Customers reported unauthorized payments after scanning QR codes at gas stations.
• Lahore (2022): Fraudulent QR codes were found at self-service banking kiosks, leading to fake transaction confirmations.

10. SIM Cloning: Bypassing OTP Authentication

Hackers clone SIM cards to intercept One-Time Passwords (OTPs) sent by banks, allowing unauthorized transactions.

Notable Cases in Pakistan:

• Islamabad (2021): 12 customers of a private bank lost ₨7.5 million due to SIM cloning scams.
• FIA Cybercrime Wing (2023): Discovered a SIM cloning ring operating from Rawalpindi, targeting online banking users.

Advanced Cyber Exploits in Pakistani Banking

11. DNS Cache Poisoning: Redirecting Users to Fake Banking Portals

Attackers inject malicious IP addresses into a bank’s DNS cache, causing users to unknowingly visit fake websites where their credentials are stolen.

Real-World Example in Pakistan:

• 2019: A DNS attack targeted MCB and Allied Bank customers, redirecting them to phishing pages.

12. Zero-Day Exploits: Attacks on FinTech & Mobile Banking Apps

Zero-day vulnerabilities in Pakistani banking apps expose users to remote access trojans (RATs) and credential theft.

Real Incidents:

• 2023: A zero-day vulnerability in a major bank’s mobile app led to the theft of ₨12.8 million within 48 hours before a patch was issued.

Physical & Transactional Exploits in Pakistan

13. ATM Jackpotting: Hacking ATM Dispensers to Steal Cash

Cybercriminals infect ATMs with malware to force cash withdrawals without physical cards.

Real Incidents:

• 2023 (Lahore): ATMs of two banks were hacked, with over ₨3.2 million withdrawn fraudulently.

14. Cheque Fraud: Altering Cheque Details Using Chemicals

Fraudsters use chemical solvents to modify cheque details and forge signatures.

Recent Cases:

Regulatory & Systemic Weaknesses

15. Cross-Border Data Flaws: Weak Safeguards for Shared Banking Data

Pakistani banks exchange sensitive financial data with Chinese and Middle Eastern banks with poor encryption practices.

Concerns from Financial Authorities:

• China: Warned Pakistan about weak cybersecurity protections in CPEC-related transactions.
• Middle East: UAE banks raised concerns over insecure financial data transfers.

16. Outsourced IT Risks: Security Flaws in Third-Party Vendors

Banks outsource IT systems to international firms like Temenos, which introduces external cybersecurity risks.

Known Issues:

Emerging Cyber Threats in Pakistani Banks

21AI-Powered Fraud Detection Evasion

Cybercriminals are using AI to bypass fraud detection systems in Pakistani banks. Machine learning models designed to detect fraudulent transactions are now being manipulated through adversarial AI techniques. Attackers generate synthetic but realistic transaction patterns that evade anomaly detection algorithms.

Real Example: In 2023, Pakistani banks reported multiple cases where AI-generated deepfake voices were used to bypass voice authentication systems for high-value transactions. These incidents led to unauthorized transfers worth ₨450 million before being flagged.

Impact on Pakistani Banks:

• AI-powered transaction laundering enables criminals to spread fraudulent transactions across multiple accounts, making detection harder.
• Adversarial AI attacks modify transaction data in real-time to deceive fraud prevention algorithms.
• Deepfake-based social engineering has been used to impersonate senior bank executives, authorizing fake fund transfers.

22. 5G Network Slicing Attacks: Exploiting 5G-Based Banking Services

The transition to 5G-enabled banking introduces new attack vectors, including unauthorized access to 5G network slices handling banking transactions.

Concerns Raised by Cybersecurity Experts:

• Pakistan’s early 5G adoption in banking has introduced new vulnerabilities yet to be addressed.

23. IoT Botnets: Hijacking Smart Devices to DDoS Banking Servers

Hackers use compromised IoT devices (smart fridges, CCTV cameras) to overload Pakistani banking servers with fake requests.

Real-World Example:

• 2023: A DDoS attack against three major Pakistani banks resulted in service disruptions for over 500,000 customers.

Key Recommendations for Pakistani Banks:

✔ Mandatory PCI DSS compliance to secure payment systems.
✔ Regular cybersecurity audits from IdealSolutions to detect vulnerabilities.
✔ AI-driven fraud detection to prevent financial crimes.
