How the NSA Allegedly Breached Global Banking Systems Through Software Exploits
Recently leaked documents and computer files suggest the U.S. National Security Agency (NSA) may have exploited vulnerabilities in commercial software to infiltrate the SWIFT global money transfer system. The revelations come from a hacker group known as the Shadow Brokers, who released data indicating NSA accessed SWIFT via service providers in the Middle East and Latin America.
Key Findings from the Leaked Data
- Windows Server Vulnerabilities: Cybersecurity expert Matt Suiche of Comae Technologies analyzed the leaks and found evidence that some SWIFT affiliates used Windows servers vulnerable to exploits published by the Shadow Brokers in 2013.
- Firewall Bypass: The NSA allegedly used tools like BARGLEE to breach Cisco firewalls protecting SWIFT service providers before deploying Microsoft exploits to gain deeper access.
- Targeted Institutions: Documents point to specific breaches, including Al Quds Bank for Development and Investment, which ran outdated Windows 2008 servers at the time.
Industry Responses
- Microsoft: Acknowledged the vulnerabilities but confirmed they were patched in recent updates. Older, unsupported Windows versions remain at risk.
- Cisco: Previously admitted firewall vulnerabilities but did not comment on the latest allegations.
- SWIFT: Downplayed risks, stating no evidence of unauthorized access to its core network but acknowledged potential breaches at client banks.
The Bigger Picture: Why SWIFT?
As the backbone of global financial transactions, SWIFT is a high-value target for intelligence agencies tracking illicit money flows. The leaked documents suggest the NSA focused on:
- Service Providers: Penetrating local messaging systems of SWIFT client banks.
- Database Queries: Using code to interrogate SWIFT servers and Oracle databases handling transactions.
Unanswered Questions
- Document Authenticity: Reuters could not independently verify the leaked files, though slides bore the NSA seal.
- EastNets’ Denial: The Dubai-based SWIFT contractor named in the documents denied being hacked.
What’s Next?
While patches have mitigated some risks, the incident underscores the ongoing cat-and-mouse game between cybersecurity defenses and state-sponsored hacking. Financial institutions must prioritize:
- Regular Updates: Ensuring all systems run supported, patched software.
- Advanced Threat Detection: Monitoring for unusual network activity.
