Sui Research revealed a way for blockchain wallets to upgrade for quantum safety without a hard fork or address changes. The approach, based on EdDSA cryptography, allows compatible networks like Solana, Sui and Near to transition securely with minimal disruption.
Cryptographer Kostas Chalkias described the breakthrough as the first backward-compatible path to quantum safety for wallets. The upgrade uses zero-knowledge proofs to verify private key control without exposing data, keeping original public keys and supporting dormant accounts.
While praised as one of the most important cryptographic advancements in recent years, the upgrade method does not apply to Bitcoin or Ethereum. These networks use different signature methods, which may need bigger changes to stay secure as quantum tech evolves.
Although quantum computers are not yet capable of breaking blockchain encryption, researchers and developers are racing to prepare. The risk of millions of wallets becoming vulnerable has triggered serious debate in the crypto community.

Google has confirmed it has not received a request from the UK government to create a backdoor in its encrypted services. The clarification comes amid ongoing scrutiny of surveillance legislation and its implications for tech companies offering end-to-end encrypted services.
Reports indicate that the UK government may be reconsidering an earlier request for Apple to enable access to user data through a technical backdoor, which is a move that prompted strong opposition from the US government. In response to these developments, US Senator Ron Wyden has sought to clarify whether similar requests were made to other major technology companies.
While Google initially declined to respond to inquiries from Senator Wyden’s office, the company had not received a technical capabilities notice—an official order under UK law that could require companies to enable access to encrypted data.
Senator Wyden, who serves on the Senate Intelligence Committee, addressed the matter in a letter to Director of National Intelligence Tulsi Gabbard. The letter urged the US intelligence community to assess the potential national security implications of the UK’s surveillance laws and any undisclosed requests to US companies.
Meta, which offers encrypted messaging through WhatsApp and Facebook Messenger, also stated in a 17 March communication to Wyden’s office that it had ‘not received an order to backdoor our encrypted services, like that reported about Apple.’
While companies operating in the UK may be restricted from disclosing certain surveillance orders under law, confirmations such as Google’s provide rare public insight into the current landscape of international encryption policy and cooperation.

The women’s dating safety app Tea has suspended its messaging feature following a cyberattack that exposed thousands of private messages, posts and images.
The app, which helps women run background checks on men, confirmed that direct messages were accessed during the initial breach disclosed in late July.
Tea has 1.6 million users, primarily in the US. Affected users will be contacted directly and offered free identity protection services, including credit monitoring and fraud alerts.
The company said it is working to strengthen its security and will provide updates as the investigation continues. Some of the leaked conversations reportedly contain sensitive discussions about infidelity and abortion.
Experts have warned that the leak of both images and messages raises the risk of emotional harm, blackmail or identity theft. Cybersecurity specialists recommend that users accept the free protection services as soon as possible.
The breach affected those who joined the app before February 2024, including users who submitted ID photos that Tea had promised would be deleted after verification.
Tea is known for allowing women to check if a potential partner is married or has a criminal record, as well as share personal experiences to flag abusive or trustworthy behaviour.
The app’s recent popularity surge has also sparked criticism, with some claiming it unfairly targets men. As users await more information, experts urge caution and vigilance.

South Korea is stepping up efforts to strengthen its cyber insurance sector as corporate cyberattacks surge across industries. A string of major breaches has revealed widespread vulnerability and renewed demand for more comprehensive digital risk protection.
Hanwha General Insurance launched Korea’s first Cyber Risk Management Centre last November and partnered with global cybersecurity firm Theori and law firm Shin & Kim to expand its offerings.
Despite the growing need, the market remains underdeveloped. Cyber insurance makes up only 1 percent of Korea’s accident insurance sector, with a 2024 report estimating local cyber premiums at $50 million, just 0.3 percent of the global total.
Regulators and industry voices call for higher mandatory coverage, clearer underwriting standards, and financial incentives to promote adoption.
As Korean demand rises, comprehensive policies offering tailored options and emergency coverage are gaining traction, with Hanwha reporting a 200 percent revenue jump in under a year.

The US Department of Justice has moved to seize over $2.3 million in Bitcoin tied to a member of the Chaos ransomware group. The funds, taken from a wallet linked to the individual known as ‘Hors’, are alleged to be proceeds of extortion and money laundering.
Chaos operates as a ransomware-as-a-service group, renting its malware to affiliates targeting Windows, Linux, and NAS systems. The group has been active since early 2025 and is known for encrypting victims’ data while demanding crypto payments under threat of public leaks.
US Federal agents accessed the wallet in April using a recovery seed phrase from an older Electrum platform and transferred the assets to a government-controlled address. The DOJ said the operation demonstrates growing success in disrupting ransomware-related crypto flows.
Despite the seizure, challenges remain as such groups evolve their tactics and benefit from the relative anonymity of decentralised platforms. Authorities stress that continued cross-agency cooperation and advances in blockchain forensics are essential in combating future threats.

Global corporations are under growing threat from increasingly sophisticated cyber attacks as AI tools boost the capabilities of malicious actors.
Allianz Life recently confirmed a breach affecting most of its 1.4 million North American customers, adding to a string of high-profile incidents this year.
Microsoft is also contending with the aftermath of a wide-scale intrusion, as attackers continue to exploit AI-driven methods to bypass traditional defences.
Cybersecurity firm DeepStrike reports that over 560,000 new malware samples are detected daily, underscoring the scale of the threat.
Each month in 2025 has brought fresh incidents. January saw breaches at the UN and Hewlett-Packard, while crypto lender zkLend lost $9.5 million to hackers in February.
March was marked by a significant attack on Elon Musk’s X platform, and Oracle lost six million data records.
April and May were particularly damaging for retailers and financial services. M&S, Harrods, and Coinbase were among the prominent names hit, with the latter facing a $20 million ransom demand. In June, luxury brands and media companies, including Cartier and the Washington Post, were also targeted.

Allianz Life has confirmed a major cyber breach that exposed sensitive data from most of its 1.4 million customers in North America.
The attack was traced back to 16 July, when a threat actor accessed a third-party cloud system using social engineering tactics.
The cybersecurity breach affected a customer relationship management platform but did not compromise the company’s core network or policy systems.
Allianz Life acted swiftly by notifying the FBI and other regulators, including the attorney general’s office in Maine.
Those impacted are offered two years of credit monitoring and identity theft protection. The company has begun contacting affected individuals but declined to reveal the full number involved due to an ongoing investigation.
No other Allianz subsidiaries were affected by the breach. Allianz Life employs around 2,000 staff in the US and remains a key player within the global insurer’s North American operations.

Thanks to AI, historians studying ancient Rome now have a powerful new tool.
A research team, including scholars from Google DeepMind and the University of Nottingham, developed a generative AI model called Aeneas that can help interpret damaged Latin inscriptions by estimating their location and date and suggesting likely missing text.
Each year, roughly 1,500 new Latin inscriptions are unearthed, ranging from imperial decrees to everyday graffiti. These inscriptions, written by ancient Romans across all social classes, offer rare, first-hand insights into daily life, language, and society.
Yet many of them are incomplete or difficult to contextualise. Traditionally, scholars must compare each inscription against hundreds of others manually — a process described as laborious and requiring exceptional expertise.
Aeneas, trained on over 170,000 Latin texts, can now predict when and where an inscription was written across the Roman Empire’s 62 provinces. In one test case, it analysed the famous Res Gestae Divi Augusti, narrowing down the date to the same two options long debated by historians.
Aeneas significantly improved research outcomes when used alongside human expertise instead of replacing it, helping scholars piece together history more efficiently than ever.

Microsoft has officially removed the infamous Blue Screen of Death (BSOD) from Windows 11 and replaced it with a sleeker, black version.
As part of the update KB5062660, the Black Screen of Death now appears briefly—around two seconds—before a restart, showing only a short error message without the sad face or QR code that became symbolic of Windows crashes.
The update, which brings systems to Build 26100.4770, is optional and must be installed manually through Windows Update or the Microsoft Update Catalogue.
It is available for both x64 and arm64 platforms. Microsoft plans to roll out the update more broadly in August 2025 as part of its Windows 11 24H2 feature preview.
In addition to the screen change, the update introduces ‘Recall’ for EU users, a tool designed to operate locally and allow users to block or turn off tracking across apps and websites. The feature aims to comply with European privacy rules while enhancing user control.
Also included is Quick Machine Recovery, which can identify and fix system-wide failures using the Windows Recovery Environment. If a device becomes unbootable, it can download a repair patch automatically to restore functionality instead of requiring manual intervention.

Online searches for VPNs skyrocketed in the UK following the introduction of new age verification rules on adult websites such as PornHub, YouPorn and RedTube.
Under the Online Safety Act, these platforms must confirm that visitors are over 18 using facial recognition, photo ID or credit card details.
Data from Google Trends showed that searches for ‘VPN’ jumped by over 700 percent on Friday morning, suggesting many attempt to sidestep the restrictions by masking their location. VPN services allow users to spoof their device’s location to another country instead of complying with local regulations.
Critics argue that the measures are both ineffective and risky. Aylo, the company behind PornHub, called the checks ‘haphazard and dangerous’, warning they put users’ privacy at risk.
Legal experts also doubt the system’s impact, saying it fails to block access to dark web content or unregulated forums.
Aylo proposed that age verification should occur on users’ devices instead of websites storing sensitive information. The company stated it is open to working with governments, civil groups and tech firms to develop a safer, device-based system that protects privacy while enforcing age limits.
