Anatomy of the Scam Email
The scam email subject line usually reads “Unpaid/Overdue Invoice” or “Final Notice” to incite urgency. The sender name spoofs a real vendor or service provider your company may use.

Attached is a document, often titled “invoice” or “statement.” Enabled macros download malware once opened. Or, it’s a fake portal grabbing your login data when accessed.
Well-crafted emails like this bypass spam filters and seem legitimate. But small details like incorrect names, logos, or email addresses may reveal it’s a scam.
How the Scam Works
The “Overdue Invoice” scam leverages urgency, familiarity, and authority to manipulate targets. Understanding the psychological tricks makes it easier to recognize before falling victim. Here’s how the scam operates at each step:
Step 1: Crafting a Credible Email
Scammers research the target company to make the email look authentic. The sender name, email address, and signature match real vendors or partners. Company logos are replicated in the attached documents.
Subject lines convey urgency like “Final Notice” and “Immediate Payment Required.” This rushed tone pressures the recipient to act quickly, overlooking red flag.
Details like dollar amounts, dates, and invoice numbers seem real. The message style mirrors a legitimate business correspondence to build familiarity.
Step 2: Directing to Malware or Phishing Sites
The email urges prompt payment and references the attached invoice document. Opening this initiates the scam.
Attachments contain macros which install malware like trojans or remote access tools when enabled. This grants scammers control over the target computer.
Alternatively, the attachment directs to a fake payment portal impersonating a real vendor site. On this phishing site, victims enter account credentials exposing sensitive data.
Step 3: Leveraging Compromised Accounts
With access to compromised accounts, scammers have multiple opportunities for exploitation. They can monitor inboxes to spy on ongoing communications and transactions.
Financial accounts can be drained through fraudulent transfers and purchases. Scammers can also reach out to contacts posing as the target requesting money or sensitive data.
Compromised business accounts provide cover to target partners, vendors, or customers with additional scams. Each exploited account expands the scam’s scope and earning potential.
Step 4: Concealing Fraudulent Activity
Scammers hide their activity within compromised accounts to avoid detection. They alter contact info and security settings to lock out the real account owner.
Communications are deleted, and documents altered to conceal fraudulent transactions. Multi-factor authentication is disabled making accounts easier to access.
With total control over accounts, scammers have ample time to exploit assets while avoiding anti-fraud alerts from banks and providers.
What to do if you have fallen victim
If you suspect you have fallen prey to an “Overdue Invoice” scam, remain calm and take immediate action to contain the damage. Follow these key steps to begin securing your accounts and assets:
Step 1: Contact Relevant Institutions
If you entered credentials, payment info, or downloaded attachments, alert associated institutions ASAP. Call banks and financial services to flag compromised accounts. Inform any vendors the scam email impersonated.
Enable transaction monitoring and strengthen fraud protections on accounts at risk. The sooner relevant parties are notified, the faster fraudulent activity can be spotted and limited.
Step 2: Change Passwords and Remove Unauthorized Access
Assume all passwords for accessed accounts are compromised. Rapidly change credentials on email, financial sites, company logins, etc. Make passwords long and complex to strengthen security.
Check accounts for unauthorized access and remove email forwarding rules, contact changes, or multi-factor authentication modifications enacted by scammers.
Step 3: Scan Devices for Malware
If you downloaded email attachments, scan associated devices to uncover malware like trojans, spyware, and remote access tools. Use up-to-date antivirus software to detect and remove discovered threats.
Also change all passwords from any potentially infected devices once cleaned to eliminate continued account access. Enable two-factor authentication where possible for added security.
Step 4: Monitor Accounts Closely
Carefully check all exposed accounts over the following weeks for signs of unauthorized access, fraudulent activity, and spear phishing attempts targeting your contacts. Report suspicious activity to associated institutions.
Request increased transaction verification where available. Update account security questions and continue using strong, unique passwords for each service.
Step 5: File a Police Report
File a report with your local law enforcement agency detailing the scam, exposed accounts, and impact experienced. Provide any documents, emails, and evidence to aid investigation and recovery efforts.
This creates an official record that can help prove fraud to institutions and help authorities identify and prosecute scammers. Records also support insurance claims associated with losses.
How to Avoid “Overdue Invoice” Scams
While no single tactic prevents all scams, layers of defense make this fraud easier to catch and limit damage from. Follow these tips to keep your business or accounts protected:
Enable Email Security
Use email security services that scan attachments, filter spam, and block phishing tactics. Features like DMARC authentication and anomaly detection identify red flags in messages.
Enable spam filters, and set security settings to block executable files, Office macros, and other dangerous attachments typical in scams.
Use Caution with Unexpected Attachments
Do not open unanticipated attachments even if seemingly from known contacts. First verify by phone or separate email such requests are legitimate and expected.
Have IT scan attachments on a separate system before accessing on company devices if urgent. Require management approval before opening to encourage scrutiny.
Limit Account Access
Restrict and closely monitor employee access to financial accounts and sensitive company data relevant to payments. Require secondary approvals for fund transfers and transactions.
Enable transaction alerts and monitor activity logs to regularly audit access. Limit account access once staff leave the company or change roles.
Beware Urgent Requests
Train staff to be wary of urgent payment requests and verify independently. No legitimate firm will threaten legal action or require immediate payment without notice.
Verify invoices match records and contact senders through known company channels if unsure. Avoid email links and handle payment offline.
Report Scams
If targeted, report scam emails to associated institutions. Forward messages to the Anti-Phishing Working Group to aid scam prevention efforts. Report fraud to the FBI’s Internet Crime Complaint Center.
Notifying key groups ensures scam patterns are tracked and resources focused on protecting other potential targets in the future.
