Know Your Breach: The National Bank of Blacksburg
Dec 20, 2019 12:35:58 PM
The target: The National Bank of Blacksburg
The take: $2.4 million
The attack vector: The attack began with a phishing email which let the hackers install malware on the compromised computer. This move let them disable and alter anti-theft and anti-fraud measures such as PIN’s, withdrawal limits, daily debit card usage limits and fraud score protections. Through their now unrestricted access to the bank’s internal account manager software, Navigator, the attackers modified or removed critical security controls. They then accessed hundreds of customer accounts to steal funds over a period of two days.
This incident highlights the profound impact one compromised system can have in the context of an organization’s overall security posture, and underscores the old adage – ‘a chain is only as strong as its weakest link’. While network and server-level protections are essential, firm must ensure that endpoint controls and user training are up to snuff.
