WhatsApp fixes security flaw in iOS and macOS apps

WhatsApp has released fixes for a critical vulnerability in its iOS and macOS apps that may have been exploited in targeted attacks. The flaw, tracked as CVE-2025-55177, stemmed from insufficient authorization in linked device synchronization and was discovered by WhatsApp’s internal security team. Meta said the bug could have allowed attackers to process malicious content from arbitrary URLs on a victim’s device.
The issue affected WhatsApp for iOS before version 2.25.21.73, WhatsApp Business for iOS 2.25.21.78, and WhatsApp for Mac 2.25.21.78, all patched in late July and early August. Researchers believe the weakness may have been chained with CVE-2025-43300, a zero-day in Apple’s ImageIO framework that was recently exploited to target individuals.

Amnesty International reported that WhatsApp has alerted certain users who may have been targeted in spyware campaigns over the past three months. The company advised affected individuals to perform a full device reset and ensure their operating system and apps remain updated. “This is a classic example of a zero-click attack, where no user interaction is needed to compromise a device,” said Donncha Ó Cearbhaill, head of Amnesty International’s Security Lab. He warned that this spyware continues to pose serious risks to journalists, activists, and human rights defenders.

Motorola Solutions Enhances Reliability of Enea Operator’s Power Grid

Motorola Solutions has announced a contract to deploy a new TETRA land mobile radio communications network for Enea Operator, one of Poland’s leading energy suppliers. The solution will provide reliable and secure voice and data communications between personnel, optimize power grid management, and enhance service reliability for 2.5 million residents across northwestern Poland.

“The continuity of energy supply and services during a crisis depends on failsafe communication between field teams, dispatchers and management staff,” said Magdalena Kordys, Vice President of Finance, Enea Operator. “A communications network independent of commercial operators strengthens our operational resilience and streamlines collaboration with emergency services.”

The new TETRA network integrates a SCADA system to remotely monitor and control grid infrastructure. A network of sensors across the grid will be able to relay critical data to the central monitoring system, using the TETRA network as the secure data pipeline. If an issue or maintenance need is detected, personnel can be immediately notified via radio.

Motorola Solutions will deploy 130 TETRA base stations, modems and digital radios, along with terminals for more than 1,000 technical vehicles, to support the operation of the integrated solution.

Designed for resilience, the TETRA network can operate on an emergency power supply for up to 36 hours in the event of a mass failure or loss of electrical network voltage. “Enea Operator’s investment in modernizing its operations will help safeguard the delivery of electricity to millions of Polish residents,” said Axel Kukuk, Vice President, Sales Europe, Motorola Solutions. “With this contract, three of Poland’s four national energy Distribution System Operators now rely on Motorola Solutions’ mission-critical communications solutions. We are proud to support the delivery of this essential service to homes, businesses, schools and hospitals across the country.”
