Criminals typically obtain unauthorized access to legitimate customer accounts by using stolen credentials, social engineering, or malicious software (for example, spyware, remote access tools) to infiltrate and monitor victims’ systems. Once an account is compromised, these actors launder illicit funds by mingling proceeds with the normal activity of the rightful account holder, often bypassing standard AML triggers by taking advantage of the account’s established profile. This tactic allows criminals to perform swift transfers, purchases, or additional layering with minimal suspicion. Techniques may involve simultaneously logging in from disparate locations, rapidly changing account information (such as recovery emails or phone numbers), or initiating high-value withdrawals shortly after anomalous logins. Online banking and custodial services frequently serve as conduits, given their remote-access vulnerabilities, lack of real-time verification, and reliance on automated risk flags. Robust measures to detect suspicious login patterns, implement multi-factor authentication, actively monitor IP addresses, and use behavioral analytics can help mitigate these risks, forcing criminals to expend greater effort or abandon compromised accounts altogether.

Unauthorized Account Access
Account Breach
Tactics
By compromising legitimate customer accounts, criminals bypass standard KYC and AML checks, gaining direct usage rights under an established profile. This serves as the primary objective, securing unhindered entry into the financial system for subsequent laundering activities.
Risks
Criminals use stolen credentials or malicious software to compromise legitimate online banking channels. Inadequate detection of unauthorized usage allows them to pose as genuine customers. By exploiting remote access and rapid transaction features, they swiftly launder illicit funds under the account's established profile with minimal suspicion, effectively bypassing common AML red flags based on account-holder history.
Indicators
Simultaneous or near-simultaneous access of the same account from geographically disparate locations that are not aligned with known user behavior.
Immediate modifications to contact or security details after suspicious login events from unknown or flagged IP addresses or devices.
Rapid movement or transfer of funds initiated shortly after a login from an unrecognized IP address or device.
Logins from geographic locations that are atypical for the user's historical access patterns.
Numerous unsuccessful login attempts.
Access from devices that have not been previously associated with the account.
Customer disputes or denies recent transactions or account changes that align with suspicious login events from unrecognized IP addresses or devices.
Large-value transactions or withdrawals executed immediately after account access from a geographic location inconsistent with the customer’s historical pattern.
Multiple consecutive failed login attempts followed by a successful login from a new or unusual device or location.
Reports or evidence of phishing attempts targeting account holders.
Malicious software or spyware detected on the user's device used to access financial accounts.
Sudden or significant shifts in transaction amounts, frequency, or recipients observed immediately after suspicious account login events.
Data Sources
- Shows all changes to account profiles (e.g., contact info, password resets), with timestamps and user identifiers.
- Identifies rapid or unusual modifications made immediately after a compromised login, supporting timely investigation of unauthorized account alterations.
Tracks failed login attempts, device fingerprints, and suspicious cybersecurity events (e.g., flagged IPs, unauthorized login alerts).
Supports the detection of compromised accounts by revealing repeated access attempts, new device usage, or known malicious IP indicators.
Captures each financial movement, including timestamp, amount, counterparty details, and channel, tied to the compromised account.
Helps investigators identify abnormal transaction patterns, unusually high-value transfers, or other anomalies occurring shortly after unauthorized account access.
- Records IP addresses, timestamps, and user sessions associated with account access.
- Helps correlate suspicious login events (e.g., from unexpected locations or times) with possible account takeover activity.
- Centralizes reported incidents of unauthorized transactions, phishing attempts, or disputed charges.
- Highlights patterns of disputed activity and connects known fraud events to compromised accounts, aiding in ongoing investigations.
- Maps transaction origin and destination locations against known customer activity patterns.
- Reveals geographical inconsistencies (e.g., transactions initiated from regions not typical for legitimate account usage), indicating potential account takeover.
Mitigations
Deploy analytics rules that correlate suspicious login events with subsequent high-risk transactions, such as large withdrawals or rapid fund transfers to newly added beneficiaries. Use behavioral biometrics to highlight deviations from typical customer spending habits immediately following anomalous logins. This targeted monitoring enables quick detection of compromised accounts that criminals use for immediate layering and laundering activities.
Implement robust multi-factor authentication (MFA) for all online banking logins. Deploy device fingerprinting to detect usage from unfamiliar devices, and enforce real-time session monitoring to block logins from flagged locations. Immediately require re-verification or lock the account if abnormal access patterns, such as consecutive failed login attempts or sudden password resets, are detected. By preventing unauthorized infiltration at the login stage, institutions significantly reduce criminals’ ability to exploit compromised accounts for laundering funds.
Regularly educate account holders about phishing tactics, social engineering, and best practices, such as using strong passwords and secure connections, to safeguard their credentials. Encourage the immediate reporting of suspicious emails, text messages, or unauthorized account changes. By minimizing credential theft, institutions lower the risk of criminals successfully compromising accounts to launder funds.
Temporarily disable or limit digital banking features when multiple failed logins, flagged IP addresses, or other high-risk indicators suggest an account may be compromised. Require re-authentication or additional verification steps before allowing high-value transfers or profile changes. This intervention impedes the immediate criminal misuse of compromised accounts.
Instruments
- Criminals use stolen credentials to access legitimate bank accounts.
- They leverage the established transaction profile to integrate illicit funds, making them appear as normal deposits or withdrawals.
- Swiftly adding new payees or updating contact details under the compromised owner’s profile enables rapid transfers to external accounts without triggering typical AML scrutiny.
- Criminals divert funds from compromised accounts into cryptocurrency exchanges or wallets.
- Rapidly converting fiat to digital assets and moving them across multiple wallet addresses hinders tracing and frustrates investigators.
- The remote-access nature of many exchanges permits these transfers to occur quickly with minimal direct oversight.
- Unauthorized access to online banking or card management portals allows criminals to exploit legitimate card credentials.
- High-value purchases or cash advances appear routine under the established customer profile, delaying detection.
- This method effectively layers illicit proceeds into everyday transactions with minimal immediate scrutiny.
- Once an account is compromised, criminals make large ATM or in-branch cash withdrawals under the rightful owner’s identity.
- Because the activity appears to be conducted by the legitimate customer, high-volume cash extractions may evade immediate suspicion, bypassing certain AML thresholds.
- Converting digital balances into physical currency helps further obscure the fund trail.
- Criminals accessing compromised stored-value or e-money accounts, which were legitimately opened by victims, can deposit or receive illicit proceeds.
- Since the compromised account already has a transaction history, sudden large inflows or outflows attract less scrutiny.
- Quick transfers to external accounts or rapid balance withdrawals enable repeated layering.
Service & Products
- Criminals may infect or phish victims to gain unauthorized access to mobile banking apps, granting direct control of legitimate accounts.
- Once inside, they rapidly transfer funds or change account details, leveraging the account’s established profile to bypass AML alerts.
- Stolen credentials grant unauthorized access to custodial wallet balances, letting criminals conceal or move illegal proceeds outside traditional banking.
- The speed and relative anonymity of digital wallet transfers make it easier to dissipate funds before detection.
- Criminals infiltrate these accounts to mingle illicit funds with routine transactions (e.g., bill payments, everyday purchases), reducing the appearance of abnormal activity.
- Rapidly initiating transfers or withdrawals from the compromised account helps funnel money with minimal suspicion.
- Compromised login credentials allow criminals to transact remotely under the guise of legitimate customers.
- By mimicking typical user behavior, they evade automated red flags and swiftly move illicit proceeds to external or layered accounts.
Actors
Cybercriminals gain unauthorized access to legitimate customer accounts through methods such as stolen credentials, social engineering, or malicious software. Once inside, they launder illicit funds by commingling them with the rightful account holder’s normal transactions. This approach:
- Leverages the account’s established profile to circumvent typical AML triggers.
- Exploits remote banking or custodial services, making it difficult for financial institutions to distinguish fraudulent activity.
Financial institutions face immediate challenges as cybercriminals initiate high-value transfers or purchases from these compromised accounts, undermining transaction monitoring and due diligence processes.
Legitimate account holders are unwittingly exploited when their accounts are compromised and used to launder funds. Criminals take advantage of the customer’s established transaction history and normal activity patterns by:
- Executing transfers or purchases under the guise of the rightful owner.
- Rapidly modifying account credentials or contact details to maintain unauthorized access.
This exploitation complicates financial institutions' efforts to detect illicit transactions, as the activity appears to align with the customer’s usual behavior.
