What Is Brokerage Account Takeover Fraud?
Brokerage account takeover fraud occurs when cybercriminals gain unauthorized access to your investment account and steal your assets. According to FINRA Regulatory Notice 21-18, these schemes commonly involve bad actors improperly accessing customer brokerage accounts to purchase or sell securities at inferior prices or to directly transfer funds out of the account.
The criminals may access your account through various methods, including compromised login credentials, phishing attacks, social engineering tactics, or exploiting security weaknesses in the brokerage platform itself.
How Account Takeover Attacks Work
Modern account takeover schemes have become increasingly sophisticated. The FBI’s Internet Crime Complaint Center has identified several common attack methods:
Social Engineering
Criminals impersonate bank or brokerage staff to extract login credentials, multi-factor authentication codes, or one-time passwords through calls, texts, and emails. Some tactics involve falsely claiming fraudulent transactions have occurred to create urgency.
Phishing Attacks
Fraudsters create sophisticated fake banking and brokerage portals that mimic legitimate institutions. They may use SEO poisoning by purchasing ads that redirect unsuspecting victims to counterfeit websites designed to harvest credentials.
Once criminals gain access, they move quickly. According to the FBI, cybercriminals rapidly wire funds to other criminal-controlled accounts, many linked to cryptocurrency wallets where funds are disbursed quickly and become difficult to trace and recover.
The Growing Epidemic: Account Takeover Fraud Statistics
The scale of brokerage account takeover fraud has reached alarming proportions. Understanding these statistics helps illustrate why broker-dealers must maintain robust security measures and why they should be held accountable when they fail to do so.
| Statistic | Figure | Source |
|---|---|---|
| Complaints since January 2025 | 5,100+ | FBI IC3 |
| Total losses since January 2025 | $262 million+ | FBI IC3 |
| Americans affected by ATO | 29% (77 million) | Security.org |
| ATO attack growth (2021-2025) | 141% | TransUnion |
According to TransUnion’s Global Fraud Report, digital account takeover volume worldwide grew 21% from the first half of 2024 to the first half of 2025. The volume of account takeover fraud has surged 141% from 2021 to 2025, making it one of the fastest-growing categories of financial crime.
Critical Window: When account takeover occurs, the FBI recommends contacting your financial institution immediately to request a recall or reversal and to obtain a Hold Harmless Letter or Letter of Indemnity. Quick action is essential because funds are often moved to cryptocurrency wallets where they become nearly impossible to trace.
Broker-Dealer Liability for Security Failures
When your brokerage account is compromised, the question of who bears responsibility for the losses is paramount. While many investors assume they have no recourse, broker-dealers have significant legal and regulatory obligations to protect customer accounts.
FINRA Rules Requiring Account Protection
The Financial Industry Regulatory Authority (FINRA) has established rules that require broker-dealers to implement adequate security measures and supervisory systems:
- FINRA Rule 3110: Requires firms to establish and maintain supervisory systems reasonably designed to achieve compliance with securities laws, including detecting and preventing unauthorized account access
- FINRA Rule 2010: Requires members to observe high standards of commercial honor and just and equitable principles of trade
- FINRA Rule 4370: Mandates business continuity plans that address data backup and recovery
SEC Regulation S-P Requirements
The Securities and Exchange Commission has strengthened cybersecurity requirements for broker-dealers through amendments to Regulation S-P. These regulations require firms to:
Written Policies
Maintain written policies and procedures addressing administrative, technical, and physical safeguards for customer records and information
Incident Response
Develop and implement written incident-response programs designed to detect, respond to, and recover from unauthorized access
Customer Notification
Notify affected individuals whose sensitive customer information was accessed or used without authorization
When broker-dealers fail to meet these obligations and their security failures enable account takeover fraud, they can be held liable for customer losses through FINRA arbitration. Our securities litigation practice has extensive experience holding negligent firms accountable.
Robinhood and Recent FINRA Enforcement Actions
Recent enforcement actions demonstrate that regulators take broker-dealer security failures seriously. These cases also establish precedent for individual investor claims.
In March 2025, FINRA ordered Robinhood Financial to pay $3.75 million in restitution to customers and fined Robinhood Financial and Robinhood Securities $26 million for violating numerous FINRA rules, including failing to respond to red flags of potential misconduct.
FINRA specifically cited that suspicious behavior and account takeovers resulted from Robinhood’s inadequate anti-money laundering systems. Additionally, thousands of accounts were opened without sufficient verification because the firm failed to establish a reasonable customer identification program.
Precedent for Recovery: These regulatory actions against major broker-dealers demonstrate that firms can and will be held accountable for security failures. Individual investors who suffered losses due to similar negligence may have valid claims for recovery through FINRA arbitration.
Common Security Failures That Enable Account Takeovers
Based on regulatory actions and investor claims, several common security failures have enabled account takeover fraud at brokerage firms:
- Failure to enforce two-factor authentication or multi-factor authentication
- Inadequate monitoring systems to detect suspicious login attempts or unusual trading activity
- Weak password protocols and credential verification procedures
- Failure to implement IP address monitoring and device recognition
- Insufficient verification procedures for wire transfers and ACH withdrawals
- Lack of real-time fraud detection and transaction monitoring
- Inadequate customer identity verification during account setup
What to Do If Your Brokerage Account Has Been Hacked
If you discover unauthorized activity in your brokerage account, time is critical. Taking the right steps immediately can significantly impact your ability to recover stolen assets and pursue legal claims against negligent parties.
Immediate Steps
Step 1: Contact Your Broker Immediately
Call your brokerage firm’s fraud department right away. Request an immediate freeze on your account and document the date, time, and name of everyone you speak with. Ask them to preserve all records related to the unauthorized access.
Step 2: Secure Your Account
Change your password and enable two-factor authentication if not already active. Update passwords on any linked email accounts or other accounts that share the same credentials. Consider requesting new account credentials entirely.
Step 3: Document Everything
Take screenshots of all unauthorized transactions, login records, and account statements. Create a detailed timeline of events. Save all communications with your broker, including emails, chat logs, and notes from phone calls.
Step 4: File Official Reports
Report the fraud to the FBI’s Internet Crime Complaint Center at ic3.gov, the Federal Trade Commission at identitytheft.gov, and the SEC’s complaint center. These reports create an official record and may assist in investigations.
Request Key Documents
The SEC recommends that victims request specific documentation from their broker-dealer:
- Complete login history showing IP addresses, device information, and timestamps
- Records of all security alerts triggered before and during the breach
- Documentation of the firm’s security measures and when they were last updated
- Copies of all wire transfer and ACH withdrawal authorizations
- Internal investigation reports regarding the breach
Preserve Your Rights: Do not sign any releases, waivers, or settlement offers from your broker-dealer without first consulting an attorney. These documents may contain language that limits or eliminates your ability to pursue full recovery of your losses.
Filing a FINRA Arbitration Claim
Most brokerage account agreements require disputes to be resolved through FINRA arbitration rather than court litigation. While this may seem like a disadvantage, FINRA arbitration offers several benefits for account takeover fraud victims.
Why FINRA Arbitration Can Work in Your Favor
| Factor | FINRA Arbitration | Traditional Court |
|---|---|---|
| Timeline | Typically 12-16 months | Often 2-4 years |
| Arbitrator Expertise | Industry-trained panelists | Jury with no financial background |
| Discovery Process | Streamlined | Extensive and costly |
| Costs | Generally lower | Significantly higher |
| Award Enforcement | FINRA enforces compliance | Separate enforcement proceedings |
Legal Theories for Account Takeover Claims
Successful FINRA arbitration claims against broker-dealers for account takeover fraud typically rely on several legal theories:
Failure to Supervise
Under FINRA Rule 3110, broker-dealers must maintain supervisory systems designed to detect and prevent irregularities and abuses. When these systems fail to identify or stop unauthorized account access, the firm may be liable for resulting losses.
Negligence
Broker-dealers owe a duty of care to protect customer accounts. Failure to implement reasonable security measures, monitor for suspicious activity, or respond appropriately to red flags can constitute negligence.
Breach of Contract
Most brokerage agreements contain provisions regarding account security and protection. When firms fail to meet their contractual obligations, customers may have claims for breach of contract.
Violation of Industry Rules
FINRA Rules 2010 and 2020 prohibit manipulative, fraudulent, or deceptive practices and require high standards of commercial honor. Security failures that enable fraud may violate these standards.
Recoverable Damages in Account Takeover Cases
Investors who successfully pursue claims against negligent broker-dealers may recover several categories of damages:
- Direct losses: The full value of assets stolen from your account, including stocks, bonds, cash, and cryptocurrency
- Market-adjusted damages: Compensation for investment gains you would have earned had the theft not occurred
- Interest: Pre-judgment interest on your losses from the date of the theft
- Attorneys’ fees: In some cases, arbitration panels may award reasonable attorneys’ fees
- Other consequential damages: Including costs incurred responding to the breach, credit monitoring, and related expenses
The measure of damages in account takeover cases can vary based on the specific circumstances, the strength of the evidence, and the arbitration panel’s findings regarding broker-dealer negligence.
Why Brokerage “Fraud Guarantees” May Not Protect You
Many investors assume their brokerage firm’s fraud guarantee will automatically cover their losses. However, these guarantees often contain significant limitations and exclusions that may leave you without protection.
Unlike credit cards and bank accounts, which have federal protections under laws like the Electronic Fund Transfer Act, brokerage accounts generally lack similar statutory protections. Most brokerage fraud guarantees are voluntary policies with conditions that must be met.
Common Exclusions in Brokerage Fraud Policies
- Customer fault: If the firm determines you were negligent in protecting your credentials, they may deny coverage
- Delayed reporting: Failure to report unauthorized activity within specified timeframes can void protection
- Social engineering: Some policies exclude losses where you were tricked into providing credentials, even through sophisticated phishing attacks
- Shared devices: Losses occurring from shared or public computers may not be covered
- Inadequate security: If you failed to enable available security features like two-factor authentication, coverage may be denied
Important Distinction: A brokerage firm denying your claim under their internal fraud policy does not eliminate your right to pursue a FINRA arbitration claim based on the firm’s own negligence. The legal standard for broker-dealer liability is different from the contractual requirements of their voluntary fraud guarantee.

Frequently Asked Questions
Can I sue my broker if my account was hacked?
While most brokerage agreements require disputes to be resolved through FINRA arbitration rather than court, you may have a valid claim against your broker-dealer if their negligence or security failures enabled the account takeover. Broker-dealers have legal obligations under FINRA rules and SEC regulations to protect customer accounts and maintain adequate supervisory systems. If they failed to meet these obligations, they can be held liable for your losses.
What if my broker says the hack was my fault?
Broker-dealers frequently attempt to shift blame to customers by claiming they failed to protect their credentials or clicked on phishing links. However, even if you made a mistake, the broker-dealer may still be liable if their security systems failed to detect or prevent the unauthorized access. The inquiry focuses on whether the firm met its regulatory obligations to maintain reasonable security measures and supervision, regardless of how the criminal initially obtained your credentials.
How long do I have to file a claim for account takeover fraud?
The time limits for filing FINRA arbitration claims vary depending on the specific legal theories involved and applicable state statutes of limitations. Generally, FINRA rules require claims to be filed within six years of the event giving rise to the claim. However, waiting too long can harm your case as evidence may be destroyed and memories fade. We recommend consulting with an attorney as soon as possible after discovering unauthorized account activity.
Will SIPC cover my losses from account takeover?
The Securities Investor Protection Corporation (SIPC) protects investors when a brokerage firm fails financially, but it does not cover losses from fraud or theft, including account takeover. This is why pursuing claims directly against the broker-dealer for negligence or security failures is often the most effective path to recovery for account takeover victims.
What evidence do I need for an account takeover claim?
Important evidence includes account statements showing unauthorized transactions, records of when you discovered and reported the fraud, documentation of your security practices (such as using strong passwords and two-factor authentication), any communications with the broker about the incident, and the broker’s response to your complaint. We help clients request critical records from broker-dealers, including login histories, security alert logs, and internal investigation reports.
How much does it cost to pursue an account takeover claim?
We handle most investment fraud cases on a contingency fee basis, which means you pay no upfront attorney fees. We only get paid if we recover money for you. The specific fee percentage and case costs such as filing fees and expert witnesses will be discussed during your free consultation so you understand all potential expenses before deciding whether to proceed.
How long does a FINRA arbitration case take?
FINRA arbitration cases typically take 12 to 16 months from filing to final hearing and award, though this can vary based on the complexity of the case and the schedules of the parties. This is generally faster than traditional court litigation, which can take two to four years or longer.
What if my broker offered a settlement that does not cover my full losses?
Broker-dealers frequently offer quick settlements to victims of account takeover fraud, often for amounts far below the actual losses suffered. Before accepting any settlement offer, consult with an attorney who can evaluate the strength of your claim and whether pursuing arbitration might result in a significantly larger recovery. Settlement offers are often negotiating positions, not final numbers.
Protect Your Rights After Account Takeover Fraud
If your brokerage account has been compromised and your broker-dealer is refusing to make you whole, you may have legal options to recover your losses. The key is taking action quickly while evidence is still available and before applicable deadlines expire.
