Bitcoin users lost a combined $1.8 million after downloading fraudulent mobile apps impersonating Sparrow Wallet on Apple's App Store, according to a lawsuit filed in the United States District Court for the Northern District of California, San Jose Division. The victims entered their recovery phrases into fake Sparrow Wallet apps, allowing thieves to drain their Bitcoin holdings. Sparrow founder Craig Raw had warned about unauthorized versions of the app as early as 2024, and Sparrow operates exclusively as a desktop wallet with no official mobile release.
Lawsuit Details Three Victims' Combined $1.8 Million Bitcoin Losses
The lawsuit names three plaintiffs who lost substantial Bitcoin holdings through the fraudulent apps. James Ramirez claims thieves drained roughly $875,000 in BTC after he used a fake wallet, and he notified both Sparrow and Apple the same day of the theft. Christopher Ellis alleges he encountered a similar app days later and lost $840,000 in crypto. Jalen Delgado alleges he lost about $120,000 in Bitcoin after downloading a fake Sparrow Wallet in May 2025.
The plaintiffs accuse Apple of failing to adequately review and remove applications masquerading as the Sparrow Wallet mobile app while promoting the App Store as a safe and trusted source for software. The lawsuit states: "Despite its extensive marketing efforts, Apple has failed to devote the necessary attention and oversight to adequately review and monitor applications distributed through the App Store. This failure has allowed cybercriminals to exploit the trust, and reputation, Apple has cultivated, resulting in the theft of funds from Apple's own customers. Absent Apple's knowing participation and meaningful support, these cybercriminal schemes could not have been carried out or brought to completion."
The plaintiffs seek damages, reimbursement, restitution, and legal fees. They argue that marketing claims about App Store safety encouraged trust in the fraudulent apps.
Sparrow Founder Warned About Fake Apps in 2024, Desktop-Only Wallet Has No Mobile Version
Sparrow founder Craig Raw had been warning about unauthorized versions of the app carrying the same name as early as 2024. The real Sparrow Wallet operates exclusively on Windows, macOS, and Linux with no official mobile release. A mobile version of the application could have been easily flagged as fraudulent given Sparrow's desktop-only nature.
Security researchers earlier identified 26 comparable fraudulent wallets mimicking brands such as MetaMask and Ledger, many capable of capturing seed phrases through phishing tactics. The fake Sparrow Wallet apps used similar tactics, prompting victims to enter their recovery phrases and granting thieves access to drain their Bitcoin holdings.
Apple Removed Fake Apps and Closed Developer Accounts
Apple states it has removed the fake Sparrow apps and closed the associated developer accounts while emphasizing its existing fraud detection measures. The company has not provided additional comment on the lawsuit's specific allegations regarding inadequate review processes or the timeline of the fraudulent apps' availability on the App Store.
