School finance teams are prime targets for cybercriminals because of the sensitive data and large financial transactions they handle. Schools maintain extensive personal and financial records, which attackers find valuable. At the same time, many educational institutions have limited cybersecurity resources, making them appear as “soft targets” with weaker defenses. This combination of value and vulnerability has led to a surge in attacks on schools. Finance directors and accounts payable staff are often directly targeted, as scammers use techniques like business email compromise to impersonate vendors or executives and trick staff into transferring funds. Given the potentially severe financial losses and disruptions (including theft of funds, data breaches, and ransomware lockdowns), it’s critical for school finance teams to understand common cyber fraud tactics and adopt strong preventative measures.

Common Cyberattack Tactics

  1. Email Account Compromise (Lack of MFA)
    One major threat is hackers hijacking email accounts of finance staff or leadership. If an email login is protected only by a password (and not secured with multi-factor authentication), attackers can steal or guess the credentials via phishing, brute-force attacks, or leaked passwords. Once they gain access, the hacker essentially becomes an insider – they can read financial communications and send emails from the legitimate account. This enables devastating fraud schemes: for instance, attackers may send out fake invoices or payment instructions from the compromised email, redirecting funds to their own accounts. Without MFA, a single phished password can thus lead to a major breach of the finance office’s email and records.
  2. Invoice Fraud & Bank Detail Changes
    Another common scheme is invoice and payment diversion fraud. Here, fraudsters impersonate a known vendor, supplier, or even a school executive and then trick staff into changing payment details. They might send a seemingly legitimate invoice but with new bank account information, or simply email the finance department claiming the vendor’s bank details have changed. If finance staff unknowingly update the details, the next payment goes straight to the criminals’ account. This type of scam is also called “mandate fraud.” Without strict verification protocols, schools have lost large sums this way. The lesson is that any request to amend vendor banking info or make an unscheduled payment must be treated with caution and verified through a trusted channel.
  3. Phishing and Social Engineering
    Phishing is one of the most prevalent attacks against schools. These are fraudulent emails (or texts/calls) crafted to trick users into a false action – such as clicking a malicious link, opening a malware-laced attachment, or divulging login credentials on a fake login page. Finance staff might receive emails that look like they come from a colleague or a supplier, asking them to log in to view an invoice or confirm account details. Social engineering tactics often accompany phishing: attackers may impersonate authority figures or trusted partners, create a sense of urgency, or exploit trust. A scam email might urgently request an immediate wire transfer or claim the head of school needs an emergency payment made right away. Phishing emails can also carry malware if a user clicks a link or opens a booby-trapped attachment. All staff should be on high alert for unsolicited requests or anything even slightly out of the ordinary in their communications.
  4. Malware and Ransomware Threats
    Schools have been increasingly hit by malware, especially ransomware. Malware can enter through email attachments, malicious links, or infected websites or USB drives. For finance teams, a common scenario is receiving an emailed invoice or document that contains malware. If opened, it could install a keylogger (to steal passwords) or ransomware that encrypts school data and systems. Ransomware is a critical threat – it can paralyze school operations, including finance systems, until a ransom payment is made. In some cases, attackers also steal data and threaten to leak it unless the ransom is paid. Preventing malware infections (through strong security measures and user vigilance) is far easier than trying to recover from one.

Warning Signs and Red Flags

Finance staff should always be on the lookout for clues that an email, invoice, or payment request could be fraudulent. Sophisticated scams can be hard to spot, but they often exhibit unusual characteristics upon closer inspection. Here are key warning signs:

  • Sender Address Anomalies: Look carefully at the sender’s email address. Fraudsters often use an address that mimics a legitimate one but with subtle differences. Even internal-looking emails can be spoofed, so verify any odd-looking internal email with IT.
  • Unfamiliar or Unexpected Sender: Be cautious if you’re contacted by a person or organization you don’t recognize – especially if they’re initiating a financial transaction. Scammers often pretend to represent official agencies or new suppliers.
  • Urgency and Pressure: Beware of urgent demands. If a message is pushing you to bypass normal procedures and act immediately, it’s likely a social engineering ploy.
  • Requests for Changes to Payment Details: Any request to change a vendor’s bank account or payment instructions should be considered high-risk by default.
  • Inconsistencies in Invoices or Documents: Fraudulent invoices may show odd formatting or errors, such as pixelated logos, different addresses, unusual wording, or duplication of invoice numbers.
  • Changes in Communication Style or Procedure: Be alert if a normally routine process suddenly changes via an informal message. A change of tone or writing style in an email from a known colleague can indicate a hacked or spoofed account.
  • Unsecure or Strange Links and Attachments: If an email includes unexpected hyperlinks or attachments, approach with caution. Hover over links to check the URL, and don’t click attachments unless sure of their legitimacy.

Best Practices and Prevention Measures

  1. Enable Multi-Factor Authentication (MFA) on All Accounts
    MFA adds an extra login step (like a code from an app) on top of passwords, so even if an attacker steals a password, they likely cannot access the account. All finance-related accounts – email, accounting systems, banking portals, etc. – should require MFA.
  2. Verify Payment Requests and Bank Detail Changes via Secondary Channels
    Always use an out-of-band verification for financial transactions, especially if there’s anything unusual about the request. Call the requester using a known telephone number to confirm the request is legitimate.
  3. Maintain Rigorous Approval Processes (Segregation of Duties)
    Implement internal controls so that no single person can unilaterally execute a significant transaction. For example, require dual approval for payments above a certain threshold.
  4. Train Staff to Recognize Phishing and Fraud
    Regular cybersecurity awareness training is essential for all staff handling finances. Conduct sessions on how to spot phishing emails, how to verify requests, and the latest scams.
  5. Secure Email and Document Handling Practices
    Work with IT to ensure there is a secure email gateway or spam filter that can block known phishing emails and scan attachments for malware. Use email encryption for sensitive data, and discourage sending unencrypted spreadsheets of confidential info.
  6. Up-to-Date Systems and Malware Protection
    Ensure that all computers and devices used by the finance team have updated antivirus/anti-malware software and that security patches are applied regularly. Maintain regular data backups for critical financial files.

When to Investigate Further

Knowing when to pause and investigate can mean the difference between catching a scam in time and suffering a loss. Finance teams should have clear guidelines on when to escalate concerns or perform additional checks:

  • Any Request with Red Flags: If an email or payment request raises any of the earlier red flags, do not proceed until you verify its authenticity.
  • Large or Unusual Transactions: For payments that are high-value or out-of-the-ordinary, build in an extra verification step.
  • Requests to Change Bank Details or Payment Procedures: Any request to change where or how you send money should trigger an investigation.
  • Unsolicited or Confidential Information Requests: If you receive an unsolicited request for sensitive info, verify the reason it is needed and confirm the request through a separate channel.
  • Suspected Account Compromise or IT Incident: If you suspect any account has been compromised, immediately escalate to IT/security teams.
  • When Verification is Lacking: If a control was skipped, investigate to confirm the transaction was legitimate.
  • Whenever “It just doesn’t feel right”: Encourage staff to trust their instincts and escalate if something seems off.

Case Studies of Attacks on School Finance Teams

Real-world incidents illustrate how cybercriminals operate and what schools can learn from past mistakes. Below are a few case studies:

  1. Fake Vendor Scam in Johnson County Schools (Tennessee)
    The finance director was deceived by an email impersonating a well-known vendor. Believing it to be real, the director wired several million dollars to a new bank account. Verification protocols were not followed, resulting in substantial losses.
    Lesson Learned: Always verify changes in payment instructions via phone or another trusted channel.
  2. Compromised Email Leads to Multi-Million Fraud in New Haven (Connecticut)
    Attackers hacked the email account of a high-level official and monitored payment conversations. They then sent fraudulent instructions from that official’s account, resulting in large unauthorized transfers.
    Lesson Learned: Use MFA on executive email accounts, and require verbal or in-person confirmation for large or unusual requests.
  3. Manor Independent School District Phishing Scam (Texas)
    Finance staff made multiple unauthorized transactions over the course of a month after being tricked by phishing emails. The scam was only noticed when funds went missing during a routine review.
    Lesson Learned: Regular reconciliation and multi-person approval are critical. Do not rely solely on email to confirm payment requests.
  4. UK School Fee Payment Diversion Scam
    Criminals intercepted or spoofed emails between schools and parents, diverting tuition payments to fraudulent accounts. Parents believed the bank details were legitimate because they appeared to come from the school.
    Lesson Learned: Secure email systems, train parents to verify bank details by phone, and communicate clear warnings about potential scams.

  5. Ransomware Attack on Fairfax County Public Schools (Virginia)
    A ransomware gang infiltrated systems and encrypted a large amount of data, including some finance records. The attack caused major disruptions and required extensive resources to recover.
    Lesson Learned: Have an incident response and disaster recovery plan. Regular offline backups are essential. Prevention measures (like patching and user awareness) reduce the chance of a successful breach.
