Malwarebytes threat research data for the first half of 2025 reveals a dramatic escalation in mobile threats, particularly targeting Android devices. According to their latest findings, malware targeting Android has surged by 151% since the start of the year, signaling a new phase in the mobile threat landscape characterized not only by increased volume but also by greater coordination and precision among attackers.

Canada has ordered Chinese video surveillance company Hikvision to cease all operations in the country, citing national security concerns. The decision was announced by Industry Minister Mélanie Joly on June 28, 2025, following a multi-step national security review under the Investment Canada Act. This review, conducted with input from Canada’s security and intelligence agencies, concluded that Hikvision’s continued presence in Canada would be “injurious to Canada’s national security”.

The ransomware landscape is experiencing unprecedented turbulence in 2025, characterized by the rapid collapse of once-dominant groups, hostile takeovers, and internal betrayals. This upheaval has exposed deep instability within the cybercriminal ecosystem, as major ransomware-as-a-service (RaaS) outfits such as RansomHub, LockBit, Everest, and BlackLock have faced abrupt shutdowns, operational failures, and even public defacements of their dark web infrastructure. What brought these powerful groups to their knees?

A patient’s death has been officially confirmed as linked to the June 2024 ransomware attack on Synnovis, a pathology services provider for the UK’s National Health Service (NHS), particularly affecting hospitals in southeast London.

The Cyber Threat Alliance (CTA) has joined a growing consensus among cybersecurity experts and organizations urging businesses to begin transitioning to quantum-resistant cryptography immediately. Their recent report, Approaching Quantum Dawn: Closing the Cybersecurity Readiness Gap Before It’s Too Late, emphasizes that quantum risk is not a distant threat but a present one, as attackers are already employing tactics like “Harvest Now, Decrypt Later.” In these attacks, adversaries steal encrypted data now with the intent to decrypt it once quantum computers become powerful enough to break current encryption methods.
