Credit unions are facing a new generation of identity-related fraud tactics that are harder to detect and even harder to stop. Attackers no longer rely solely on fake IDs or obvious scams. Instead, they exploit real people, real credentials and legitimate-looking behaviors. They move through call centers, digital banking channels, indirect lending and even check fraud, often blending in with normal member activity almost seamlessly.
This evolving threat landscape demands a new approach. Traditional identity verification tools, designed for single identity checks or siloed systems, simply can’t keep up. Credit unions need to think in terms of continuous digital trust: Layering “threat signals,” monitoring unusual activity and adjusting protections in real time. Here, we’ll explore where cybercriminals are hiding today, how they exploit vulnerabilities and what credit unions can do to stay ahead, without sacrificing a smooth member experience.
Where Today’s Identity-Related Fraud Is Hiding
Legitimate users, illegitimate purpose:
Some of the hardest identity-related fraud to catch involves real people with real driver’s licenses and Social Security numbers. Cybercriminals now pay individuals to open accounts in person or online. Onboarding looks clean, but later those accounts are used for identity-related fraud or money laundering. Because they pass every initial check, the identity-related fraud only becomes visible once money starts moving in atypical ways.
Old-school check scams are back:
Digital transformation has made checks seem outdated, but that’s exactly why cybercriminals are targeting them again. Mail theft and check washing are rising, along with ATM manipulation and mail rerouting. These “low-tech” tactics succeed because institutions are focused elsewhere.
Call centers as easy entry points:
Call centers remain one of the most overlooked attack vectors. According to a TransUnion industry report, more than half of financial institutions report an increase in call center fraud.By repeatedly calling and then piecing together bits of information from different reps, cybercriminals can eventually reset a password or alter account info, a tactic known as “social engineering by fragmentation.” Often, the goal isn’t immediate theft but account takeover via changes to credentials, authentication or contact details. Attackers frequently pose as stressed or rushed members, pressuring agents to bypass security checks.
5 Steps to Improve Your Credit Union’s Resilience
1. Watch behavior, not just logins.
Correct credentials don’t guarantee legitimacy. Instead, monitor for deviations from normal behavior – for example, if a member who usually checks their balance monthly suddenly updates an address, adds payees or wires funds overseas within minutes. Quietly flagging these shifts enables verification without disrupting the member’s experience.
2. Track where the money goes.
Identity-related fraud often occurs when funds move to new or suspicious accounts. Verifying recipients and monitoring unusual transfer patterns can stop identity-related fraud before it succeeds.
3. Make identity verification ongoing, not one-time.
Identity proofing shouldn’t stop at onboarding. Use continuous verification checks on device, location and behavior in every session. If something looks off, step up security seamlessly – most members will never notice, but cybercriminals will.
4. Consolidate tools into smarter platforms.
Managing separate solutions for ID proofing, identity threat detection and access management can leave dangerous gaps. Look for platforms that unify these capabilities, enabling coordinated, real-time responses.
5. Strengthen call center defenses.
Equip staff with tools that flag risky phone numbers, devices or behaviors without slowing legitimate service. Adaptive trust models allow suspicious calls to be escalated, while trusted members experience minimal friction.
What Credit Unions Can Do Next
Fraud is evolving rapidly, and the solution isn't more friction – it's smarter, real-time trust decisions. Today’s identity-related fraud doesn’t always look like fraud. It might look like a normal login, a routine call or a familiar transfer.
Resilient credit unions don’t just block identity-related fraud – they make smarter, member-centric decisions. The guiding question should always be: Does this action make sense for this member, right now? If not, that’s the signal to step up verification efforts.
