A Welcome Mat for Fraud: Why Checks and Legacy ACH are CAMs’ Weakest Links

Written by CINC SYSTEMS | Apr 15, 2026 9:38:07 PM

Community association management (CAM) professionals are trained to spot the red flags of physical neglect. A hairline fracture in a balcony, a water stain on a ceiling, or a flickering fire alarm panel are visible signs that a property’s integrity is at risk. We don’t ignore them because we know that "deferred maintenance" is just another term for impending catastrophe.

But when it comes to payments, many CAM companies are operating with the equivalent of a leaky roof. Whether it’s a physical check sitting in a dropbox or a homeowner’s bank details stored on a shared drive, legacy payment processes are one of your company’s greatest liabilities.

In 2024, global losses from the rising tide of cybercrime reached a staggering $9.5 trillion—a sophisticated global economy, now super-charged by AI technology. CAM companies, which handle high-volume transactions with relatively lean teams, are prime targets.

The most common entry point for fraud is also the most traditional: the paper check. 

 

The Habitual Risk of the Paper Check

In many communities, the paper check remains "business as usual." But the process many homeowners and boards have used for decades is the most prevalent form of payment exploitation, accounting for 65% of all reported fraud attempts.

Think of a physical check as a slow-moving, unencrypted piece of sensitive data. Mail theft has seen a massive resurgence, and recent postal processing changes have introduced new delays between when a check is mailed and when it is officially processed—increasing the risk of exposure.

Once intercepted, checks become raw material for "check washing." Criminals can easily erase the payee and amount, replacing them with their own details while leaving the original, valid signature intact. Fraudsters often deposit these altered checks into "mule" accounts or use mobile deposit features to move the money instantly. 

Recovery isn’t a simple fix. The victim typically doesn't even realize they’ve been targeted until weeks or even months later. A homeowner may only discover the fraud when they review their monthly bank statement—or, more awkwardly, when they receive a late payment notice and a fine from the management company for an assessment they thought they’d already paid.

CAM teams are then pulled into a frantic cycle of manual reconciliation, calls to the bank, and investigations. This "forensic accounting" is a distraction from the work of building community.

While many CAM companies have transitioned to ACH payments to avoid the physical risks of mail, this can create a false sense of security that masks other vulnerabilities.

 

The ACH Myth: Why ‘Digital’ Doesn’t Mean ‘Secure’

ACH payments are faster and more efficient than paper checks, but they are far from bulletproof. In the community management world, the risk often isn't the transaction itself, but how data is handled behind the scenes. If your process involves collecting paper authorization forms or receiving voided checks via email, you could be a prime target for bad actors.

In many CAM offices, sensitive bank account data is stored in ways that would make a cybersecurity expert cringe:

●    Unencrypted Shared Drives: Authorization forms saved as PDFs in folders accessible to the entire staff.

●    Physical Vulnerability: Voided checks and paper forms sitting in unlocked filing cabinets or on desks.

●    Email Exposure: Homeowners emailing their routing and account numbers.

Because CAM companies manage large volumes of transfers, they are prime targets for Business Email Compromise (BEC). This is currently the top fraud scam, with nearly two-thirds of businesses targeted in 2025.

In the past, these scams were relatively easy to spot. We looked for red flags like poor grammar, awkward phrasing, or suspicious email addresses. But AI has changed the game. Today’s attackers can use Large Language Models (LLMs) to mimic the professional tone of legitimate emails from vendors or board members.

Ultimately, any ACH process that requires you to see or store bank details is a security breach waiting to happen.

 

The Cost of a Compromised Reputation

When a breach occurs, the damage extends far beyond the immediate financial loss. A single incident can trigger a chain reaction that many CAM companies aren’t prepared to handle: legal and regulatory fallout. Insurance complications. Operational paralysis. The erosion of homeowner and board trust.

A seemingly minor email compromise can quickly escalate into a nightmare scenario involving insurance adjusters, legal counsel, and angry clients. It’s a stark reminder that in today’s landscape, a small gap in payment security doesn't stay small for long.
