In September 2025, court documents revealed detailed information on a major data violation at JammingThe largest exchange of cryptocurrency based in the United States, which affected more than 69,000 customers and has led to estimated losses up to $ 400 million.
The breach, which started in September 2024, involved an employee in TaskusAn outsourcing company based in Texas providing customer support services for Coinbase, named Ashita Mishra.
Based in Indore, India, Mishra would have stolen sensitive customer data, including social security numbers, bank account details, identifiers, names, addresses, emails and account sales, photographing up to 200 customer files per day.
She sold these images to pirates for about $ 200 each, raising data on more than 10,000 customers on her personal device at the time of her arrest in January 2025.

The violation was part of a wider plot described as a “hub and radius” network, where Mishra and accomplices, including team leaders and Taskus operations directors, were recruited by a group of pirates known as “comm”, which would have been composed of young English -speaking criminals.
These pirates used the stolen data to usurp the identity of Coinbase support staff, running social engineering scams that prompted users to transfer cryptocurrency to fraudulent portfolios, certain victims losing all their life savings or pension funds.
Coinbase detected a suspicious activity in the months preceded on May 11, 2025, when an unknown threat player sent an email to the company by asking for a ransom of $ 20 million in bitcoin so as not to disclose stolen data.
Coinbase refused to pay, by rather invented the users and regulators assigned by May 30, 2025, ending his relationship with Taskus and licensed the employees involved. The company has also implemented stricter initiate orders, tightened remote control policies and offered a bonus of $ 20 million for information leading to the arrest and conviction of the authors.
The affected customers were reimbursed and Coinbase provided a year of free credit and identity catering monitoring via IDX, including an insurance policy of $ 1 million.
The trial brought in the South New York district alleges that Taskus tried to hide the violation in dismissing 226 employees in Indore in January 2025 and by rejecting its HR team investigating the incident, accusing the cabinet of not implementing adequate security measures such as multi-fateer encryption or authentication.
Taskus challenges the allegations of systemic problems, saying that only two employees were involved and that he quickly reported the Violation of Coinbase. The incident has raised concerns about the risks of customer support outsourcing, a coinbase faced with reputation fallout and in progress, although the company pushes the arbitration to mitigate financial and advertising damage.
For customers, the risk of identity and financial fraud persists, as stolen data can circulate on the dark web. Coinbase advises the activation of two-factor-based two-factor authentication, the use of the withdrawal authorization list and the prudence of unlined calls or emails requesting fund transfers.
The violation erodes confidence in Coinbase as a secure platform, potentially leading customers to competitors like Binance or Kraken. The perception of the public of the management by coinbase of the incident – refusing the ransom of $ 20 million and delaying disclosure – can harm its brand.
The reimbursement of affected customers and the offer of $ 20 million in bonuses, as well as the legal costs of current prosecution, tend the finances of Coinbase. Potential corps regulatory fines such as dry or CFTC for inadequate data protection could add additional pressure.
Prosecutions in the South New York district, with arbitration resistant complainants, could lead to regulations or significant judgments if Coinbase is deemed responsible for negligence in the supervision of its outsourcing partner.
The exposure of social security numbers, bank details and government identity documents increases the probability of long -term identity theft, fraud or phishing attacks. Stolen data circulating on the Dark web can lead to a new operation, despite the Coinbase credit surveillance offer and $ 1 million via IDX.
For the cryptography industry
The violation highlights vulnerabilities in the outsourcing of customer support, which has probably prompted regulators to impose more strict data protection and cybersecurity standards in the cryptography sector. This could increase compliance costs for exchanges.
Other exchanges can reassess their dependence on third-party suppliers such as Taskus, potentially switch to internal support or more secure outsourcing models with robust encryption and multi-faters authentication.
Large-scale violations can shake up investors’ confidence, which potentially leads to short-term reductions in cryptocurrencies or a reduction in negotiation volumes, users withdraw funds for self-cire portfolios.
Taskus faces inadequate security allegations and the attempt to conceal the violation in dismissing employees. This could lead to lost contracts, legal liabilities and difficulties in attracting new customers.
The violation underlines the human element as a critical vulnerability, even in organizations with strong technical defenses. Companies in all sectors can invest more in monitoring, training and employee access controls.
The success of the “comm” in the exploitation of stolen data via identity scams highlights the growing sophistication of social engineering, pushing businesses to educate users on the recognition of fraudulent communications.
The magnitude of the violation can stimulate calls for stronger protections of consumers in cryptographic space, including compulsory violation disclosure, standardized security protocols or government -supported insurance for digital assets.
With authors operating through the courts (for example, employees based in India and English -speaking pirates), international cooperation on cybercrime surveys will be critical, which will potentially lead to new frameworks for the cross -border application.
Coinbase response – Refunds, bonuses and improved controls – can mitigate certain damage, but the incident highlights the continuous challenges of securing digital assets in a rapidly evolving threat landscape.
