Customer Due Diligence Needs a Control Plane, Not a Checklist: By Victor Mendez

0

The Checklist Delusion at the Heart of the Control

Why a Complete File Is Not a Working Control

Most financial institutions still treat customer due diligence (CDD) as a file to be completed rather than a control to be operated. The moment the file is signed off, the customer moves into the book, and the customer risk profile quietly freezes. A complete
customer due diligence file is not a working control.

Done right, the mechanism is engineered as a control plane that orchestrates evidence, decisions, and accountability across the customer lifecycle. Run as a checklist, the risk profile goes stale, the high risk cases surface too late, and the audit trail
collapses on contact with a supervisor.

What the Standard Actually Requires

FATF Recommendation 10 Frames Four Continuous Obligations

Every serious standard already describes customer due diligence (CDD) as continuous and risk-calibrated. FATF Recommendation 10 requires financial institutions to identify the customer, verify identity from reliable independent sources, understand the purpose
of the business relationship, and conduct ongoing monitoring across the life of that relationship (1).

UK Money Laundering Regulations, Regulation 28

Regulation 28 of the Money Laundering Regulations 2017 is the operative rule in the UK: identify and verify customers, take reasonable measures to verify beneficial owners, and assess the purpose and intended nature of the business relationship (3). The
rule anchors that satisfaction in identity verification from an independent source, and the decision has to be made again every time the underlying facts move.

Ongoing Monitoring Is a Statutory Duty, Not a Best Practice

The same regulation, at subsection 28(11), defines ongoing monitoring as the part of customer due diligence that runs continuously — scrutiny of the customer’s activities across the relationship and keeping the underlying records up to date (4). For the
operational evidence behind that argument — [why periodic review fails operationally as ongoing monitoring](https://www.finextra.com/blogposting/31323/event-driven-kyc-refresh-why-periodic-review-fails-operationally)
— the case is already made in detail.

EU AML Regulation and the End of Transposition Gaps

Article 20 of Regulation (EU) 2024/1624 makes the same components directly applicable across every Member State from 10 July 2027, closing the national transposition gaps the old directive left behind (5). Article 26 elevates ongoing monitoring to a relationship-level
duty and requires obliged entities to keep the documents, data and information up to date as part of that duty (6).

FinCEN’s Four Core Elements

Under the US anti money laundering regime, 31 CFR 1010.230 and the 2016 CDD Final Rule preamble set out four core elements of customer due diligence: customer identification and verification, beneficial ownership identification and verification, understanding
the nature and purpose of the relationship to develop a customer risk profile, and ongoing monitoring with risk-based updates to customer information (7).

 

Why the Checklist Model Breaks Under Real Customer Risk

The Risk-Based Approach Is Incompatible With Uniform Checks

FATF Recommendation 1 requires measures commensurate with assessed money laundering and terrorist financing risk — enhanced where risk is higher, simplified where lower-risk conditions are demonstrably met (2). A uniform checklist is non-compliant by design,
because it applies the same measures to every potential customer regardless of what the risk assessment requires. A control plane calibrates; it mitigates risks where they concentrate.

Static Files Cannot Track Risk Profiles That Move

Financial institutions operating at any scale watch the customer risk profile change in ways the onboarding file will never see: new counterparties, new jurisdictions, adverse media on a beneficial owner, politically exposed persons status acquired mid-relationship.
A file captured at onboarding is a photograph of a moment. Customer risk management is a live variable, and customer due diligence captured once at onboarding cannot represent the customer the firm is actually serving a year later.

Escalation Triggers Do Not Fire Themselves

Enhanced due diligence is only effective when the trigger fires the moment the facts change: a new high risk third country exposure, a beneficial owner flagged on a sanctions list, high risk counterparties surfacing mid-relationship, a pattern in the customer’s
activities that does not match the declared business. A checklist has no trigger. A control plane does, and the financial crime exposure in a high risk segment is where the difference shows up first.

The Control Plane Mechanism in Four Jobs

Evidence Capture as a Continuous Input Layer

The first job is to capture evidence continuously from reliable, independent sources. Verification of the customer’s identity is the starting point, not the endpoint. Beneficial ownership data, transaction patterns, counterparty exposure, sanctions screening
and adverse media feeds all flow into the same evidence layer. Under this model the customer due diligence (CDD) process becomes an input pipeline rather than a filing cabinet. For a potential customer at onboarding the pipeline captures the initial file,
and the FinCEN CDD Final Rule explicitly requires covered financial institutions to keep customer information current on a risk basis.

Risk Scoring and Event-Driven Monitoring as the Decision Layer

The second job is to score every potential customer — turning that evidence into a customer risk score that actually drives decisions, and firing the monitoring events that keep the score current. In a checklist model the risk level is typically a categorical
field completed at onboarding; in the decision layer the score is a continuously recalculated output of live customer due diligence. EBA/GL/2023/03 pushes financial institutions in the same direction (14). Event-driven triggers sit on top of the score. Threshold
breaches, counterparty changes, geography shifts, politically exposed persons alerts, beneficial ownership changes — each fires a calibrated action against the relevant customer file, and each surfaces suspicious transactions before they accumulate.

Accountability as the Named Decision Layer

The third job is the one checklists never had: every material decision has to attach to a named human with authority. FATF Recommendation 18 and the Basel Committee’s sound management guidance both anchor the aml compliance programme to a senior officer
whose concerns must be heard at board level (8). In the UK that officer is the Money Laundering Reporting Officer at SMF17 under the FCA’s Senior Managers Regime, with a personal duty of responsibility for failings in their area (9). This is the discipline
[the control plane analogy applied to KYC infrastructure more broadly](https://www.finextra.com/blogposting/31285/control-plane-thinking-treat-kyc-like-payments-infrastructure-not-a-one-off-check)
is really describing: the decision record has to be legible to the named officer who is liable for it.

What the FCA Saw When the Control Ran as a Checklist

Nationwide: Five Years of a Frozen File

When the FCA fined Nationwide Building Society £44 million in December 2025 for failings in financial crime controls, the operative finding was that the firm had ineffective systems for keeping customer due diligence (CDD) up to date and for monitoring transactions
across a nearly five-year window, leaving it unable to identify, assess, monitor or manage the money laundering risks across its personal current account base (10) — existing customers onboarded and then effectively frozen while the financial crime risk in
their accounts moved on without them. The customer due diligence file was complete on day one and uninformative on every day after.

Barclays: Missing at the Start, Missing Throughout

The pattern repeats in the July 2025 Barclays action on the poor handling of financial crime risks. In the Stunt & Co matter the FCA’s operative finding was verbatim and short: Barclays “did not gather enough information at the start of the relationship
or carry out proper ongoing monitoring” (11). In just over a year, £46.8 million from a known money laundering operation moved through one customer relationship. Read against the Regulation 28 obligation — know the purpose and intended nature of the business
relationship, monitor continuously — the supervisory language names the customer due diligence lifecycle gap directly.

Monzo: The “No Identified Risk” Default

The July 2025 Monzo Final Notice completes the set. The FCA found a risk assessment framework that defaulted most personal customers to “no identified risk” and an onboarding default that accepted obviously implausible information — customers using famous
London landmarks as their residential address (12). The failure was not in the diligence of the compliance team but in the absence of a mechanism that forced the risk assessment of a potential customer to be earned rather than defaulted, leaving the whole
base of high risk customers statistically invisible to the people responsible for managing them.

FCA 2025 enforcement patterns in customer due diligence failures at Nationwide, Barclays and Monzo: frozen files, missing information at onboarding, and "no identified risk" defaults.

 

Beneficial Ownership and the Adequate, Accurate, Up-to-Date Standard

Why a One-Time Beneficial Owner File Cannot Meet the Standard

FATF tightened Recommendation 24 in March 2022 to require that beneficial ownership information on legal persons be adequate, accurate and up-to-date (13). A file captured at onboarding and never refreshed cannot meet any of those three tests after the first
ownership change, corporate restructuring, or nominee substitution. It is the hardest test of a control plane — identifying the owner once is the easy part, and keeping those checks current on the people behind the legal person is the part financial institutions
systematically underestimate.

Calibrating the Control Across the Risk Spectrum

Simplified, Standard and Enhanced as Bands Inside One Control Plane

Simplified due diligence is not a shortcut. It applies only where lower-risk conditions are demonstrably met, and the burden of proof sits with the firm: positive evidence is the burden, not the absence of negative evidence, and low risk customers have to
remain an output of the risk assessment rather than an input that bypasses it.

The escalation path is not a separate workflow. Politically exposed persons, high risk third country exposure, unusual transaction patterns tied to terrorism financing risks, adverse media on a beneficial owner — each triggers a calibrated intensification
of the standard customer due diligence process inside the same mechanism, not a parallel regime bolted on at the side.

What the Control Plane Gives the Firm That the Checklist Cannot

A Defensible Answer to the Question Regulators Actually Ask

The question a supervisor asks on an examination visit is not “do you have a customer due diligence policy?” It is “show me how you knew this customer’s risk profile was accurate on 12 March, and show me who decided that.” A control plane answers that question
on demand, at the level of an individual decision, with the evidence, the risk score, the trigger history and the named decision owner attached. A checklist answers with a file.

The three financial institutions the FCA cited in 2025 did not fail because their compliance teams were careless or their aml compliance budgets were thin. They failed because the mechanism ran as a form rather than as a live control, and when the customer
relationships moved, the files did not move with them. Those are the regulatory requirements the three firms missed, and the financial crime exposure that followed was structural rather than accidental. A complete file will never beat a live mechanism when
the regulator walks in.

North Korea’s crypto heist playbook is expanding and DeFi keeps getting hit

0

Less than three weeks after North Korea-linked hackers used social engineering to hit crypto trading firm Drift, hackers tied to the nation appear to have pulled off another major exploit with Kelp.

The attack on Kelp, a restaking protocol tied into LayerZero’s cross-chain infrastructure, suggests an evolution in how North Korea-linked hackers operate, not just looking for bugs or stolen credentials, but exploiting the basic assumptions built into decentralized systems.

Taken together, the two incidents point to something more organized than a string of one-off hacks, as North Korea continues to escalate its efforts to hijack funds from the crypto sector.

“This is not a series of incidents; it is a cadence,” said Alexander Urbelis, chief information security officer and general counsel at ENS Labs. “You cannot patch your way out of a procurement schedule.”

More than $500 million was siphoned across the Drift and Kelp exploits in just over two weeks.

How Kelp was breached

At its core, the Kelp exploit did not involve breaking encryption or cracking keys. The system actually worked the way it was designed to. Rather, attackers manipulated the data feeding into the system and forced it to rely on those compromised inputs, causing it to approve transactions that never actually occurred.

“The security failure is simple: a signed lie is still a lie,” Urbelis said. “Signatures guarantee authorship; they do not guarantee truth.”

In simpler terms, the system checked who sent the message, not whether the message itself was correct. For security experts, that makes this less about a clever new hack and more about exploiting how the system was set up.

“This attack wasn’t about breaking cryptography,” said David Schwed, COO of blockchain security firm SVRN. “It was about exploiting how the system was set up.”

One key issue was a configuration choice. Kelp relied on a single verifier, essentially one checker, to approve cross-chain messages. That is because it’s faster and simpler to set up, but it removes a critical safety layer.

LayerZero has since recommended using multiple independent verifiers to approve transactions in the fallout, similar to requiring multiple signatures on a bank transfer. Some in the ecosystem have pushed back on that framing, saying that LayerZero’s default setup was to have a single verifier.

“If you’ve identified a configuration as unsafe, don’t ship it as an option,” Schwed said. “Security that depends on everyone reading the docs and getting it right is not realistic.”

The fallout has not stayed limited to Kelp. Like many DeFi systems, its assets are used across multiple platforms, meaning problems can spread.

“These assets are a chain of IOUs,” Schwed said. “And the chain is only as strong as the controls on each link.”

When one link breaks, others are affected. In this case, lending platforms like Aave that accepted the impacted assets as collateral are now dealing with losses, turning a single exploit into a wider stress event.

Decentralization marketing

The attack also exposes a gap between how decentralization is marketed and how it actually works.

“A single verifier is not decentralized,” Schwed said. “It’s a centralized decentralized verifier.”

Urbelis puts it more broadly.

“Decentralization is not a property a system has. It is a series of choices,” he said. “And the stack is only as strong as its most centralized layer.”

In practice, that means even systems that appear decentralized can have weak points, especially in the less visible layers like data providers or infrastructure. Those are increasingly where attackers are focusing.

That shift may explain Lazarus’ recent targeting.

The group has begun zeroing in on cross-chain and restaking infrastructure, Urbelis said, the parts of crypto that move assets between systems or allow them to be reused.

These layers are critical but complex, often sitting underneath more visible applications. They also tend to hold large amounts of value, making them attractive targets.

If earlier waves of crypto hacks focused on exchanges or obvious code flaws, recent activity suggests a move toward what could be called the industry’s plumbing, the systems that connect everything together, but are harder to monitor and easier to misconfigure.

As Lazarus continues to adapt, the biggest risk may not be unknown vulnerabilities, but known ones that are not fully addressed.

The Kelp exploit did not introduce a new kind of weakness. It showed how exposed the ecosystem remains to familiar ones, especially when security is treated as a recommendation rather than a requirement.

And as attackers move faster, that gap is becoming both easier to exploit and far more expensive to ignore.

Bitcoin bounces above $76,000 as DeFi suffers $16 billion exodus after major hack

0

Bitcoin held above $76,000 on Monday, rebounding from overnight lows as the broader crypto market remained steady despite Iran war risks.

The largest cryptocurrency climbed about 2.4% over the past 24 hours, recovering from a dip below $74,000 earlier in the session. Ether (ETH), XRP, Solana (SOL) and other major altcoins also mirrored bitcoin’s move, as the broad-market CoinDesk 20 rose 1.7%.

That resilience comes against a shaky macro backdrop. U.S. President Donald Trump said Sunday that American forces had fired on and seized an Iranian-flagged cargo ship, warning of further escalation while Tehran refuses to strike a deal. A fragile ceasefire is set to expire later this week.

Oil prices jumped 6% to near $90, while the S&P 500 and Nasdaq slipped modestly, down around 0.3%-0.4%.

Crypto equities were mixed. Coinbase (COIN) and bitcoin treasury firm Strategy (MSTR) gained roughly 2%, while Circle (CRCL) and ether treasury Bitmine (BMNR) edged lower by 1%-2%.

“The fact that prices have not fully retraced despite new tensions suggests some genuine demand,” said Jasper De Maere, trader at Wintermute, pointing to recent spot ETF inflows as a supporting factor. Unlike earlier rallies this year, he said, the current move appears less driven by leverage.

That said, the path forward remains tied to geopolitics. A renewed ceasefire could push bitcoin back toward $80,000, while further escalation may keep markets under pressure.

For now, capital continues to concentrate in large-cap assets like bitcoin, De Maere noted, with riskier altcoins lagging, a pattern typical of market environments driven by macro headlines.

DeFi reels from $292 million KelpDAO hack

Elsewhere from the current price action, tensions are still high in the DeFi sector following the biggest crypto exploit of the year.

The $292 million KelpDAO hack cascaded across the market, as a vulnerability allowed the attacker to drain funds that were then used as collateral across lending protocols.

Because those assets were widely integrated into DeFi, the impact quickly spread, with users rushing to withdraw funds amid fears of bad debt and contagion.

Total value locked (TVL) across DeFi protocols fell by $14 billion over the past two days, according to DefiLlama data, even as asset prices remained steady.

DeFi TVL (DeFiLlama)

DeFi TVL dropped to about $85 billion, its lowest level in a year and roughly 50% below October peaks. Aave, the largest lending protocol that was central in the exploit, saw around $10 billion in deposits withdrawn.

“There’s a tremendous risk-reward imbalance in DeFi,” David Shuttleworth from Anchorage Digital’s protocol team said. “Users will no longer accept the slightly higher (and sometimes lower) than risk-free rate they get by depositing in lending pools,” especially given the latest wave of exploits across protocols.

Dune Analytics Reveals 47% of LayerZero OApps Use Minimal DVN Security Following KelpDAO Hack

0

Analysis of 2,665 LayerZero OApp contracts shows nearly half rely on single-validator security configurations, the same setup that exposed KelpDAO’s rsETH to exploitation.

Dune Analytics published an open analysis on Monday examining Decentralized Validator Network (DVN) security configurations across ~2,665 active OApp contracts on LayerZero over the past 90 days. The research found that 47% of OApps operate with a 1-of-1 DVN security floor—the most minimal configuration requiring only a single validator—while 45% use 2-of-2 configurations and approximately 5% employ 3-of-3 or higher. KelpDAO’s rsETH token, which was targeted in a recent exploit, fell into the 1-of-1 bracket.

The analysis provides open-source methodology and queryable data, inviting community feedback on DVN security standards across the LayerZero ecosystem. The findings highlight structural vulnerabilities in cross-chain bridge security, as single-validator configurations create single points of failure for protocol assets and user funds routed through LayerZero’s omnichain infrastructure.

Bitmine Immersion Pushes Ether Holdings Near 5M ETH

0

Bitmine Immersion Technologies, the world’s largest public holder of Ether, increased its ETH treasury last week with another large purchase.

The company acquired 101,627 ETH during the week of April 13 to April 19, according to a press release and an accompanying Form 8-K filing with the US Securities and Exchange Commission on Monday.

The purchase marks Bitmine’s largest Ether buy since Dec. 15, 2025, according to chairman Tom Lee. “Bitmine has maintained the increased pace of ETH buys in each of the past four weeks, as our base case ETH is in the final stages of the ‘mini-crypto winter,’” Lee said.

Following the purchase, Bitmine said it held 4,976,485 ETH valued at roughly $11.5 billion at a reference price of $2,301 per token. The company also holds 199 Bitcoin (BTC), a $200 million stake in Beast Industries, a $107 million stake in Eightco Holdings and $1.12 billion in cash. The company’s total crypto and cash holdings are $12.9 billion.

The latest update extends Bitmine’s lead among public company Ether treasuries as crypto balance sheet strategies continue to spread across public markets.

Bitmine is 82% of the way to the “alchemy of 5%”

In holding 4.98 million ETH, Bitmine now owns more than 4% of total Ether circulating supply.  The company said its broader goal remains to reach the “alchemy of 5%,” a long-term target it has been working toward through repeated large-scale purchases.

The purchase came after Bitmine recently started trading on the New York Stock Exchange after uplisting from the NYSE American as the company expanded its share buyback program.

Bitmine has also expanded its staking operations through its MAVAN (Made in America Validator Network) platform. The system is designed to support institutional-grade Ethereum staking with an emphasis on performance and security.

The company reported that 3.33 million ETH is currently staked, generating annualized staking revenues of over $200 million.

At Paris Blockchain Week 2026, Lee said the recent crypto slump was a “mini crypto winter,” and predicted that Ether could climb above $60,000 over the next few years.
