Malicious apps on Google Play infected 19 million users with banking trojan

Security researchers from Zscaler’s ThreatLabz team uncovered 77 malicious Android applications on the Google Play Store, collectively downloaded over 19 million times, that distributed the Anatsa banking trojan, TeaBot, and other malware families.

Anatsa, active since at least 2020, has evolved to target over 831 banking, fintech and cryptocurrency apps globally, including platforms in Germany and South Korea. These campaigns now use direct payload installation with encrypted runtime strings and device checks to evade detection.

Deploying as decoy tools, often document readers, the apps triggered a silent download of malicious code after installation. The Trojan automatically gained accessibility permissions to display overlays, capture credentials, log keystrokes, and intercept messages. Additional malware such as Joker, its variant Harly, and adware were also detected.

Following disclosure, Google removed the identified apps from the Play Store. Users are advised to enable Google Play Protect, review app permissions carefully, limit downloads to trusted developers, and consider using antivirus tools to stay protected.

Brave uncovers vulnerability in Perplexity’s Comet that risked sensitive user data

Perplexity’s AI-powered browser, Comet, was found to have a serious vulnerability that could have exposed sensitive user data through indirect prompt injection, according to researchers at Brave, a rival browser company.

The flaw stemmed from how Comet handled webpage-summarisation requests. By embedding hidden instructions on websites, attackers could trick the browser’s large language model into executing unintended actions, such as extracting personal emails or accessing saved passwords.

Brave researchers demonstrated how the exploit could bypass traditional protections, such as the same-origin policy, showing scenarios where attackers gained access to Gmail or banking data by manipulating Comet into following malicious cues.

Brave disclosed the vulnerability to Perplexity on 11 August, but stated that it remained unfixed when they published their findings on 20 August. Perplexity later confirmed to CNET that the flaw had been patched, and Brave was credited for working with them to resolve it.

Copilot policy flaw allows unauthorized access to AI agents

Administrators found that Microsoft Copilot’s intended ‘NoUsersCanAccessAgent’ policy, which is designed to prevent user access to certain AI agents, is being ignored. Some agents, including ExpenseTrackerBot and HRQueryAgent, remain installable despite global restrictions.

Microsoft 365 tenants must now use per-agent PowerShell commands to disable access manually. This workaround is both time-consuming and error-prone, particularly in large organisations. The failure to enforce access policies raises concerns regarding operational overhead and audit risk.

The security implications are significant. Unauthorised agents can export data from SharePoint or OneDrive, run RPA workflows without oversight, or process sensitive information without compliance controls. The flaw undermined the purpose of access control settings and exposed the system to misuse.

To mitigate this risk, administrators are urged to audit agent inventories, enforce Conditional Access policies, for example, requiring MFA or device compliance, and consistently monitor agent usage through logs and dashboards.

Gmail accounts targeted in phishing wave after Google data leak

Hackers linked to the ShinyHunters group have compromised Google’s Salesforce systems, leading to a data leak that puts Gmail and Google Cloud users at risk of phishing attacks.

Google confirmed that customer and company names were exposed, though no passwords were stolen. Attackers are now exploiting the breach with phishing schemes, including fake account resets and malware injection attempts through outdated access points.

With Gmail and Google Cloud serving around 2.5 billion users worldwide, both companies and individuals could be targeted. Early reports on Reddit describe callers posing as Google staff warning of supposed account breaches.

Google urges users to strengthen protections by running its Security Checkup, enabling Advanced Protection, and switching to passkeys instead of passwords. The company emphasised that its staff never initiates unsolicited password resets by phone or email.

INTERPOL reports over 1,200 arrests in Africa-wide cybercrime operation

INTERPOL has announced that a continent-wide law enforcement initiative targeting cybercrime and fraud networks led to more than 1,200 arrests between June and August 2025. The operation, known as Serengeti 2.0, was carried out across multiple African states and focused on ransomware, online fraud, and business email compromise schemes. Authorities reported the recovery of approximately USD 97.4 million, allegedly stolen from more than 88,000 victims worldwide.

In Angola, police closed 25 unauthorised cryptocurrency mining sites, reportedly operated by 60 Chinese nationals. In Zambia, authorities dismantled a large-scale fraudulent investment scheme involving cryptocurrency platforms, which is estimated to have defrauded around 65,000 individuals of roughly USD 300 million. Fifteen suspects were detained, and assets, including domains, mobile numbers, and bank accounts, were seized.

In a separate raid in Lusaka, police disrupted a suspected human trafficking network and confiscated hundreds of forged passports from seven different countries.

INTERPOL has previously noted that Africa’s rapid uptake of digital technologies, particularly in finance and e-commerce, has increased the scope for cybercriminal activity. At the same time, comparatively weak cybersecurity frameworks have left financial institutions and government systems exposed to data breaches, economic losses, and disruption to trade.

Separately, in June, a Nigerian court sentenced nine Chinese nationals to prison for running an online fraud syndicate that recruited young Nigerians. Following the verdict, China’s ambassador to Nigeria proposed the creation of a joint working group to investigate cybercrime involving Chinese nationals in the region.

Google Cloud’s new AI tools expand enterprise threat protection

Following last week’s announcements on AI-driven cybersecurity, Google Cloud has unveiled further tools at its Security Summit 2025 aimed at protecting enterprise AI deployments and boosting efficiency for security teams.

The updates build on prior innovations instead of replacing them, reinforcing Google’s strategy of integrating AI directly into security operations.

Vice President and General Manager Jon Ramsey highlighted the growing importance of agentic approaches as AI agents operate across increasingly complex enterprise environments.

Building on the previous rollout, Google now introduces Model Armor protections, designed to shield AI agents from prompt injections, jailbreaking, and data leakage, enhancing safeguards without interrupting existing workflows.

Additional enhancements include the Alert Investigation agent, which automates event enrichment and analysis while offering actionable recommendations.

By combining Mandiant threat intelligence feeds with Google’s Gemini AI, organisations can now detect and respond to incidents across distributed agent networks more rapidly and efficiently than before.

SecOps Labs and updated SOAR dashboards provide early access to AI-powered threat detection experiments and comprehensive visualisations of security operations.

These tools allow teams to continue scaling agentic AI security, turning previous insights into proactive, enterprise-ready protections for real-world deployments.

Musicians report surge in AI fakes appearing on Spotify and iTunes

Folk singer Emily Portman has become the latest artist targeted by fraudsters releasing AI-generated music in her name. Fans alerted her to a fake album called Orca appearing on Spotify and iTunes, which she said sounded uncannily like her style but was created without her consent.

Portman has filed copyright complaints, but says the platforms were slow to act, and she has yet to regain control of her Spotify profile. Other artists, including Josh Kaufman, Jeff Tweedy, Father John Misty, Sam Beam, Teddy Thompson, and Jakob Dylan, have faced similar cases in recent weeks.

Many of the fake releases appear to originate from the same source, using similar AI artwork and citing record labels with Indonesian names. The tracks are often credited to the same songwriter, Zyan Maliq Mahardika, whose name also appears on imitations of artists in other genres.

Industry analysts say streaming platforms and distributors are struggling to keep pace with AI-driven fraud. Tatiana Cirisano of Midia Research noted that fraudsters exploit passive listeners to generate streaming revenue, while services themselves are turning to AI and machine learning to detect impostors.

Observers warn the issue is likely to worsen before it improves, drawing comparisons to the early days of online piracy. Artists and rights holders may face further challenges as law enforcement attempts to catch up with the evolving abuse of AI.

Australia weighs cyber militia to counter rising digital threats

Cyberattacks are intensifying worldwide, with Australia now ranked fourth globally for threats against operational technology and industrial sectors. Rising AI-powered incursions have exposed serious vulnerabilities in the country’s national defence and critical infrastructure.

The 2023–2030 Cyber Security Strategy designed by the Government of Australia aims to strengthen resilience through six ‘cyber shields’, including legislation and intelligence sharing. But a skills shortage leaves organisations vulnerable as ransomware attacks on mining and manufacturing continue to rise.

One proposal gaining traction is the creation of a volunteer ‘cyber militia’. Inspired by the cyber defence unit in Estonia, this network would mobilise unconventional talent, retirees, hobbyist hackers, and students, to bolster monitoring, threat hunting, and incident response.

Supporters argue that such a force could fill gaps left by formal recruitment, particularly in smaller firms and rural networks. Critics, however, warn of vetting risks, insider threats, and the need for new legal frameworks to govern liability and training.

Pilot schemes in high-risk sectors, such as energy and finance, have been proposed, with public-private funding viewed as crucial. Advocates argue that a cyber militia could democratise security and foster collective responsibility, aligning with the country’s long-term cybersecurity strategy.
