Coinbase was aware of a data breach involving insider information for several months before making it public.
=====================================================================================
In a shocking turn of events, Coinbase, one of the world's leading cryptocurrency exchanges, experienced a significant data breach between January and May 2025. The breach, which exposed sensitive data of approximately 69,461 users, was primarily an insider abuse case at an offshore customer support partner, TaskUs India [2][3].
The incident was first uncovered in January when an India-based TaskUs contractor was caught photographing customer data and leaking it in exchange for bribes. Upon discovery, Coinbase promptly dismissed over 200 TaskUs employees linked to the incident [2].
The breach, however, came to light again in May when Coinbase received an extortion threat. The attack was tied to a sophisticated social engineering campaign targeting offshore support agents [1][2][3].
The breach cost Coinbase an estimated $307 million in Q2 2025 remediation and related expenses, revised down from an earlier $400 million estimate [1][2]. The company rejected a $20 million ransom demand and subsequently strengthened security by shifting support operations to U.S.-based hubs and enhancing fraud detection [3].
Despite the breach and revenue setbacks, Coinbase reported increased net income of $1.43 billion for the quarter [1]. However, the incident has triggered regulatory scrutiny and multiple lawsuits alleging inadequate data security and breach response [5].
The compromised data included full names, contact details, partial Social Security numbers, limited bank account information, and images of government-issued identification such as driver's licenses and passports [2][3]. Fortunately, passwords and cryptocurrency private keys were not compromised.
The attackers aimed to collect customer data in order to impersonate the platform and trick users into handing over their crypto assets [1]. Similar phishing attacks were thwarted by Binance and Kraken [1].
Following the data breach, TaskUs carried out a mass layoff affecting more than 200 employees, with only two individuals identified as the main suspects [2]. Five former TaskUs employees claimed that the employee and a suspected accomplice sold Coinbase customer data to hackers for payment [2].
Reports of the Coinbase data breach drew significant attention and raised concerns among users in mid-May [6]. Stricter security measures were implemented by Coinbase following the data breach [3].
This incident serves as a reminder for all digital platforms to prioritise security and maintain vigilance against insider threats. As the digital landscape continues to evolve, so too must our defence strategies to protect user data and maintain trust.
