ATS’ Experience with BEC Protection
These aren’t theoretical scenarios—they reflect the kinds of threats our team has remediated, either directly through ATS or as part of their broader field experience. Whether coordinating with insurance carriers, neutralizing persistent access, or navigating post-incident obligations like eDiscovery, our team understands the real consequences of email compromise and what it takes to move forward stronger.
Multi-Stage Invoice Fraud at an Education Institution
An education nonprofit faced overlapping compromises of a staff account and shared mailbox. The attacker quietly exfiltrated data and submitted multiple fraudulent invoices. ATS traced the timeline across six months, helped link multiple alerts into a single insurance claim, and supported eDiscovery across 250,000+ documents—reducing cost, accelerating resolution, and initiating lasting process changes.
POS Infiltration Following a Phishing Email
A restaurant chain’s initial phishing compromise escalated into a PCI breach affecting 2 million cardholders. Threat actors reverse-engineered POS workflows and injected custom malware to exfiltrate payment data across hundreds of locations. Our DFIR lead played a critical role in decoding thousands of lines of obfuscated malware and coordinating with PCI authorities over a four-month forensic engagement.
Vendor Spoofing Leads to Financial Loss
A financial services organization paid over $15,000 to fraudulent vendor domains designed to mimic legitimate business contacts. ATS analysts identified the attacker’s domain spoofing tactics and helped the client notify affected partners, close exposure windows, and implement protective DNS monitoring.
Credential Reuse Sparks Tax Fraud
After falling for a phishing message, a CPA reused the same credentials for email and remote desktop software—allowing threat actors to file a slew of fraudulent tax returns. ATS identified the attack vector, cut off remote access, supported a business impact insurance claim, and migrated the user to a secure, business-grade email system.
OneDrive Exploit Targets Real Estate Firm
An attacker compromised a real estate employee’s email and dropped a phishing file in OneDrive. The file, disguised as a shared document, was blasted to hundreds of recipients and linked to a spoofed login page behind a Russian domain. ATS identified the file, deleted it before mass compromise, and led eDiscovery on a large trove of data from the compromised account.
Ransomware Attack Triggered by Job Application
A manufacturing firm received a zero-day exploit hidden in a resume. The attacker escalated from an HR workstation to domain-wide ransomware, exfiltrating hundreds of GBs of data. Our team’s current DFIR lead executed a pitchfork recovery model: forensic preservation, parallel restoration, and full timeline analysis. The case was later linked to a broader campaign targeting venture-funded firms.
Targeted Email Compromise at a Healthcare Provider
An HR employee clicked a phishing link, leading to endpoint compromise, lateral movement, and ransomware deployment. ATS identified the source, enforced MFA, and coordinated the forensic handoff—helping the organization stabilize operations and meet disclosure requirements tied to protected health data.
Protect What BEC Attacks Are Targeting
ATS brings the right combination of security leadership, hands-on response, and implementation expertise to stop BEC threats at every stage—from attempted intrusion to recovery. If you’re dealing with a BEC incident now or want to prevent the next one, we’re ready to help.
