Over 40 Malicious Firefox Extensions Target Cryptocurrency Wallets, Stealing User Assets

Cybersecurity researchers have uncovered over 40 malicious browser extensions for Mozilla Firefox that are designed to steal cryptocurrency wallet secrets, putting users’ digital assets at risk.

“These extensions impersonate legitimate wallet tools from widely-used platforms such as Coinbase, MetaMask, Trust Wallet, Phantom, Exodus, OKX, Keplr, MyMonero, Bitget, Leap, Ethereum Wallet, and Filfox,” Koi Security researcher Yuval Ronen said.

The large-scale campaign is said to have been ongoing since at least April 2025, with new extensions uploaded to the Firefox Add-ons store as recently as last week.

AT&T rolls out “Wireless Lock” feature to block SIM swap attacks

AT&T has launched a new security feature called “Wireless Lock” that protects customers from SIM swapping attacks by preventing changes to their account information and the porting of phone numbers while the feature is enabled.

This new feature has been available for some customers for almost a year and has now been rolled out to all AT&T customers.

SIM swap attacks are when cybercriminals port, or move, a targeted phone number to a device under their control. This allows them to intercept the target’s calls, texts, and multi-factor authentication codes to breach further accounts, such as email, banking, and cryptocurrency wallets.

Malware on Google Play, Apple App Store stole your photos—and crypto

A new mobile crypto-stealing malware called SparkKitty was found in apps on Google Play and the Apple App Store, targeting Android and iOS devices.

The malware is a possible evolution of SparkCat, which Kaspersky discovered in January. SparkCat used optical character recognition (OCR) to steal cryptocurrency wallet recovery phrases from images saved on infected devices.

When installing crypto wallets, the installation process tells users to write down the wallet’s recovery phrase and store it in a secure, offline location.

The browser, which became available as a public beta for macOS and Windows in October 2022 and June 2023, respectively, blocks all trackers by default, does not engage in personalized search profiling, and offers powerful anonymity tools.

Texas House passes strategic Bitcoin reserve bill

The Texas House of Representatives has passed the third reading of SB 21, a bill that seeks to establish a strategic Bitcoin reserve in the state. The bill passed in a 101–42 vote and will now go to Texas Governor Greg Abbott to either sign into law or veto.

SB 21, authored by state Senator Charles Schwertner, establishes a Bitcoin reserve that is managed by the state’s comptroller. The legislation allows the comptroller to invest in any cryptocurrency with a market cap above $500 billion over the previous 12-month period. Currently, the only cryptocurrency fitting the requirement is Bitcoin.

Before the vote, state Representative Giovanni Capriglione said to the chamber that the bill was a “pivotal moment in securing Texas’s leadership in the digital age with the passage of our strategic Bitcoin reserve. Now, we embrace a modern asset with traditional properties for future promise.” The bill passed in the Texas Senate in a 25–5 vote on March 6.

From Blockchain to Brainwaves: Coinbase Co-Founder Fred Ehrsam Enters the Neurotech Race with Non-Invasive BCI Startup Nudge

Fred Ehrsam, billionaire co-founder of Coinbase, is shifting his next big bet from cryptocurrency to the human brain, unveiling a non-invasive brain-computer interface designed to modulate brain activity with sound waves.

Ehrsam’s entry as the latest competitor to join the race to develop accessible brain-computer interfaces (BCIs) follows similar recent efforts from tech leaders like Elon Musk, Jeff Bezos, and Bill Gates.

On April 8, Ehrsam’s startup, Nudge, unveiled its first product, the Nudge Zero. A noninvasive brain interface device that uses ultrasound to modulate brain activity, the technology represents the first start-up venture to pursue this unique approach with BCI technology.
