BEC attackers often use tools designed to collect and store credentials obtained through phishing or malware. These tools can store large amounts of data, which scammers can later use or sell.
Fake Domain Registration
Scammers frequently register domain names that are slight variations of legitimate company domains. These fake domains are used to send deceptive emails that appear from a genuine source but are part of a BEC scheme.
Caller ID Spoofing for Vishing
BEC scammers use vishing (voice phishing), where they spoof caller IDs to make phone calls appear as if they're coming from a trusted number within the organization or from a known business partner.
Automated Scripts
Scammers may use automated scripts to send phishing emails in bulk. These scripts can personalize emails with the recipient’s name or other details, making the scam more convincing.
Proxy Servers and VPNs
BEC scammers often use proxy servers or VPNs to hide their location and evade detection. This makes it more difficult for authorities to trace the scam back to its source.
Deepfake Technology
Advanced scammers employ deepfake audio or video technology to create realistic simulations of a person’s voice or appearance, typically a senior executive, to request fraudulent transactions or sensitive information.
Tools and Technologies to Mitigate BEC Risk
As automation, artificial intelligence, and machine learning enhance the sophistication of business email compromise attacks, they also improve the effectiveness of tools and technologies designed to prevent such attacks.
Security operations centers (SOCs) are becoming more resilient with the integration of AI and automation, providing analysts with better tools to prioritize alerts effectively. Furthermore, traditional technologies, including email filtering tools and endpoint protection platforms, benefit from AI and machine learning advancements.
The primary tools and technologies cybersecurity teams use to mitigate risks and reduce potential damages from BEC attacks include:
