Russia pushes mandatory messaging app Max on all new devices

Russia will require all new mobile phones and tablets sold starting in September, including a government-backed messenger called Max. Developed by Kremlin-controlled tech firm VK, the app offers messaging, video calls, mobile payments, and access to state services.

Authorities claim Max is a safe alternative to Western apps, but critics warn it could act as a state surveillance tool. The platform is reported to collect financial data, purchase history, and location details, all accessible to security services.

Journalist Andrei Okun described Max as a ‘Digital Gulag’ designed to control daily life and communications.

The move is part of Russia’s broader push to replace Western platforms. New restrictions have already limited calls on WhatsApp and Telegram, and officials hinted that WhatsApp may face a ban.

Telegram remains widely used but is expected to face greater pressure as the Kremlin directs officials to adopt Max.

VK says Max has already attracted 18 million downloads, though parts of the app remain in testing. From 2026, Russia will also require smart TVs to come preloaded with a state-backed service offering free access to government channels.

Microsoft limits certain companies’ access to the SharePoint early warning system

Microsoft has limited certain Chinese companies’ access to its early warning system for cybersecurity vulnerabilities following suspicions about their involvement in recent SharePoint hacking attempts.

The decision restricts the sharing of proof-of-concept code, which mimics genuine malicious software. While valuable for cybersecurity professionals strengthening their systems, the code can also be misused by hackers.

The restrictions follow Microsoft’s observation of exploitation attempts targeting SharePoint servers in July. Concerns arose that a member of the Microsoft Active Protections Program may have repurposed early warnings for offensive activity.

Microsoft maintains that it regularly reviews participants and suspends those violating contracts, including prohibitions on participating in cyber attacks.

Beijing has denied involvement in the hacking, while Microsoft has refrained from disclosing which companies were affected or details of the ongoing investigation.

Analysts note that balancing collaboration with international security partners and preventing information misuse remains a key challenge for global cybersecurity programmes.

Europol warns that the $50,000 Qilin reward is fake

Europol has warned that a reported $50,000 reward for information on two members of the Qilin ransomware group is fake. The message, circulating on Telegram, claimed the suspects, known as Haise and XORacle, coordinate affiliates and manage extortion operations.

Europol clarified that it does not operate a Telegram channel and that the message does not originate from its official accounts, which are active on Instagram, LinkedIn, X, Bluesky, YouTube, and Facebook.

Qilin, also known as Agenda, has been active since 2022 and, in 2025, listed over 400 victims on its leak website, including media and pharmaceutical companies.

Recent attacks, such as the one targeting Inotiv, demonstrate the group’s ongoing threat. Analysts note that cybercriminals often circulate false claims to undermine competitors, mislead affiliates, or sow distrust within rival gangs.

Fed urges banks to embrace blockchain innovation

Federal Reserve Vice Chair for Supervision Michelle Bowman has warned that banks must embrace blockchain technology or risk fading into irrelevance. At the Wyoming Blockchain Symposium on 19 August, she urged banks and regulators to drop caution and embrace innovation.

Bowman highlighted tokenisation as one of the most immediate applications, enabling assets to be transferred digitally without intermediaries or physical movement.

She explained that tokenised systems could cut operational delays, reduce risks, and expand access across large and smaller banks. Regulatory alignment, she added, could accelerate tokenisation from pilots to mainstream adoption.

Fraud prevention was also a key point of her remarks. Bowman said financial institutions face growing threats from scams and identity theft, but argued blockchain could help reduce fraud.

She called for regulators to ensure frameworks support adoption rather than hinder it, framing the technology as a chance for collaboration between the industry and the Fed.

Google Cloud boosts AI security with agentic defence tools

Google Cloud has unveiled a suite of security enhancements at its Security Summit 2025, focusing on protecting AI innovations and empowering cybersecurity teams with AI-driven defence tools.

VP and GM Jon Ramsey highlighted the growing need for specialised safeguards as enterprises deploy AI agents across complex environments.

Central to the announcements is the concept of an ‘agentic security operations centre,’ where AI agents coordinate actions to achieve shared security objectives. It represents a shift from reactive security approaches to proactive, agent-supported strategies.

Google’s platform integrates automated discovery, threat detection, and response mechanisms to streamline security operations and cover gaps in existing infrastructures.

Key innovations include extended protections for AI agents through Model Armour, covering Agentspace prompts and responses to mitigate prompt injection attacks, jailbreaking, and data leakage.

The Alert Investigation agent, available in preview, automates enrichment and analysis of security events while offering actionable recommendations, reducing manual effort and accelerating response times.

Integrating Mandiant threat intelligence feeds and Gemini AI strengthens detection and incident response across agent environments.

Additional tools, such as SecOps Labs and native SOAR dashboards, provide organisations with early access to AI-powered threat detection experiments and comprehensive security visualisation capabilities.

Rapper Bot dismantled after 370,000 global cyberattacks

A 22-year-old man from Oregon has been charged with operating one of the most powerful botnets ever uncovered, Rapper Bot.

Federal prosecutors in Alaska said the network was responsible for over 370,000 cyberattacks worldwide since 2021, targeting technology firms, a central social media platform and even a US government system.

The botnet relied on malware that infected everyday devices such as Wi-Fi routers and digital video recorders. Once hijacked, the compromised machines were forced to overwhelm servers with traffic in distributed denial-of-service (DDoS) attacks.

Investigators estimate that Rapper Bot infiltrated as many as 95,000 devices at its peak.

The accused administrator, Ethan Foltz, allegedly ran the network as a DDoS-for-hire service, temporarily charging customers to control its capabilities.

Authorities said its most significant attack generated more than six terabits of data per second, making it among the most destructive DDoS networks. Foltz faces up to 10 years in prison if convicted.

The arrest was carried out under Operation PowerOFF, an international effort to dismantle criminal groups offering DDoS-for-hire services.

US Attorney Michael J. Heyman said the takedown had effectively disrupted a transnational threat, ending Foltz’s role in the sprawling cybercrime operation.

Grok chatbot leaks spark major AI privacy concerns

Private conversations with xAI’s chatbot Grok have been exposed online, raising serious concerns over user privacy and AI safety. Forbes found that Grok’s ‘share’ button created public URLs, later indexed by Google and other search engines.

The leaked content is troubling, ranging from questions on hacking crypto wallets to instructions on drug production and even violent plots. Although xAI bans harmful use, some users still received dangerous responses, which are now publicly accessible online.

The exposure occurred because search engines automatically indexed the shareable links, a flaw echoing previous issues with other AI platforms, including OpenAI’s ChatGPT. Designed for convenience, the feature exposed sensitive chats, damaging trust in xAI’s privacy promises.

The incident pressures AI developers to integrate stronger privacy safeguards, such as blocking the indexing of shared content and enforcing privacy-by-design principles. Users may hesitate to use chatbots without fixes, fearing their data could reappear online.
