RIAs, broker-dealers, and fintech companies face SEC cybersecurity rules, Regulation S-P breach notification requirements, and business email compromise attacks that specifically target wire transfer processes. ARIA monitors all three simultaneously.
Financial services firms hold three things attackers want: client funds (wire fraud), sensitive financial data (worth significantly more on resale than general PII — account numbers, portfolio values, and SSNs in combination enable a range of downstream fraud), and credentials that provide direct access to financial accounts. Attackers go where the return-to-effort ratio is highest. A registered investment adviser managing $200M in client assets may have fewer security controls than a major bank while holding comparable access to client wealth.
The asymmetry is a calculated choice by threat actors. Business email compromise operations targeting financial services firms are often run by organized criminal groups with the operational patience to spend weeks or months inside an email environment waiting for the right wire transfer discussion to intercept. The FBI's IC3 reported $2.7 billion in adjusted losses from BEC in 2022, with financial services firms — including smaller RIAs and family offices — among the most targeted organizations.
Registered investment advisers and broker-dealers must adopt and implement written policies and procedures addressing cybersecurity risk reasonably designed to protect against risks to their operations or clients. Significant cybersecurity incidents must be reported to the SEC on Form ADV or Form BD. Clients must be notified in writing within 30 days of an incident that materially impacts them or their data. Effective August 2023 for advisers with $1.5B+ AUM; August 2024 for smaller advisers.
Broker-dealers, investment advisers, and investment companies must develop and implement written incident response programs for unauthorized access to customer financial information. Customers must be notified within 30 days of the firm becoming aware of a breach affecting their information. The 30-day clock starts from awareness, not discovery — making rapid detection critical.
FINRA's cybersecurity practice guidance — while not a binding compliance mandate — describes industry-recognized controls including access monitoring, multi-factor authentication, incident response planning, and vendor risk management. ARIA addresses the access monitoring and incident documentation elements directly. FINRA examiners evaluate cybersecurity practices during routine examinations; a documented, operating monitoring program is substantively better than a policy document alone.
Client portal access monitoring. Anomalous login patterns on your CRM or client portal are often the first visible sign of account takeover: login from a country the user has never accessed from, login at a time inconsistent with the user's historical patterns, multiple failed authentication attempts followed by a successful login from a new IP. Each of these alone can be benign; the combination is a reliable indicator. ARIA correlates identity events to surface the pattern rather than generating individual low-confidence alerts.
Wire transfer anomaly detection. The BEC attack sequence is consistent: compromise the target's email, monitor communications for wire transfer discussions or pending transactions, intercept and redirect by impersonating a vendor, client, or counterparty at the critical moment. ARIA monitors the email compromise step — the moment the attacker establishes access is when they're most detectable, because they immediately change the email environment to maintain access: inbox rules that silently forward copies of all email to an external address, OAuth grants that give a third-party application persistent read access, MFA configuration changes.
Email security monitoring. BEC starts with a compromised email account. For Microsoft 365 environments, ARIA monitors Exchange Online for the indicators of initial compromise: new inbox rules forwarding to external addresses, logins from IPs not previously associated with the user, MFA method changes, admin role grants. For Google Workspace, ARIA monitors the equivalent events in Google Workspace Admin logs. Catching the compromise at this stage — before a fraudulent wire request is sent — is the only reliable way to prevent funds movement.
Microsoft 365 and Azure AD monitoring. Most RIAs use M365 for email and Azure AD for identity. ARIA monitors the identity-layer changes that attackers make to establish persistence: new global administrator account creation, MFA policy changes or disables, conditional access policy modifications, trusted domain additions, application permission grants to unfamiliar third-party apps. These changes happen immediately after an attacker gains initial access and before the legitimate administrator notices.
API abuse detection. Fintech products expose APIs that authenticated users interact with at scale. ARIA monitors server-side request patterns: unusual request rates from specific authenticated accounts (a user making 10,000 API calls per hour rather than the typical 50), requests for data sets outside the normal user access scope, failed API key authentication patterns that suggest brute force against service credentials. These signals are consistent across financial data APIs, trading APIs, and banking integration APIs.
Service account monitoring. Fintech infrastructure relies heavily on service accounts with elevated permissions to internal systems and financial APIs. Service accounts making interactive login requests (a service account that normally only authenticates via mTLS is now logging in via a browser), connecting from IPs outside your infrastructure's known ranges, or accessing data sets outside their normal operating scope are strong compromise indicators. ARIA monitors service account behavior specifically because service accounts are common attacker targets for privilege escalation.
Secrets management alerting. Fintech systems handle API keys, OAuth tokens, and service credentials at high volume. ARIA monitors for credential exposure patterns: processes reading secret stores at unexpected times, new processes accessing environment variable files that contain credentials, and error log patterns that indicate API key exposure in application output. These patterns often precede or accompany a supply chain or insider access event.
Rapid incident response with regulatory timeline support. SEC's 30-day client notification requirement and Regulation S-P's 30-day awareness-to-notification requirement mean you need complete, accurate incident documentation quickly. ARIA's post-incident evidence package documents the detection timeline (when the event occurred, when ARIA detected it, when an analyst confirmed it), the scope of impact (which accounts, systems, or data were affected), and the containment actions taken. This gives your legal and compliance team a complete factual record from which to assess materiality, draft notifications, and respond to regulatory inquiries.
BEC wire fraud is the highest-dollar cybercrime category by adjusted losses. The attack pattern is remarkably consistent across thousands of documented cases, which makes the precursor indicators reliable:
Initial email access: CFO or controller's M365 account is compromised via phishing, credential stuffing, or MFA fatigue. Attacker logs in from a foreign IP they've never used.
Login from an IP geolocation and ASN the user has never accessed from. Anomalous authentication event triggers investigation within seconds of occurrence.
Persistence establishment: Attacker creates inbox rules to forward copies of all incoming email to an external address. Attacker may also grant an OAuth app persistent read access to the mailbox, surviving a future password reset.
New inbox rule creation to an external forwarding address. OAuth grant to an application not in your approved list. Both are immediate alerts — typically the window to prevent funds movement.
Wire intercept: Attacker monitors email for wire transfer discussions. Weeks later, intercepts a real transfer by impersonating a vendor or counterparty via a lookalike domain, redirecting the wire.
Attacker was detected and evicted at step 1 or 2 — before they ever reached step 3. The wire discussion they were waiting to intercept never occurred while they had access.
Once a wire clears, recovery is difficult and time-sensitive. The FBI's financial fraud kill chain — SWIFT recall, correspondent bank coordination, FinCEN filing — has a narrow window measured in hours. ARIA's value is catching the compromise before the wire request is sent, not after.
