Microsoft issues out-of-band patch for critical WSUS flaw

Microsoft has released an urgent out-of-band update to address a critical vulnerability (CVE-2025-59287) in Windows Server Update Services (WSUS), affecting Windows Server versions from 2012 to 2025. This remote code execution flaw allows unauthenticated attackers to execute arbitrary code due to insecure deserialization of untrusted data. Only servers with the WSUS role enabled are at risk. Administrators unable to apply the patch should consider disabling the WSUS role or blocking inbound traffic to ports 8530 and 8531. The update is cumulative and requires a system reboot after installation. WSUS is deprecated but remains supported, with Microsoft advising a transition to alternatives like its cloud-based Intune service.

Why Aren’t Antivirus Programs Enough To Protect Crypto?

Cryptocurrency has introduced a decentralized approach to financial transactions, but it faces significant security challenges, including vulnerability to cyberattacks, theft, and fraud. Traditional antivirus software has limitations, such as reliance on signature-based detection, which struggles against emerging and polymorphic malware. Behavioral detection methods also have shortcomings, as stealth malware can disguise itself and conditional activation can evade detection. Fileless malware techniques and human error, such as phishing and weak password hygiene, further complicate security. To enhance security, cryptocurrency users should adopt a multi-layered strategy that includes using hardware wallets for offline storage of private keys, implementing multi-factor authentication (MFA), and utilizing dedicated anti-malware tools. Safe browsing habits and regular software patches are also essential, along with securely backing up private keys.

The end of Windows 10 has been a boon for one particular Linux distro – and I’m not surprised

Support for Windows 10 officially ended recently, leaving users with unsupported PCs to consider transitioning to MacOS or Linux. Zorin OS launched its significant upgrade, Zorin OS 18, which received over 100,000 downloads in two days, with 72% coming from Windows machines. Échirolles, France, has transitioned its town hall computers to Free & Open Source software, including Zorin OS, although only 10% of those machines are using it. Microsoft is offering an additional year of security updates for Windows 10 for a fee. The "End of 10" campaign provides guidance for Windows 10 users transitioning to Linux. Linux has a wide range of applications and is considered accessible for those familiar with Windows. Continuing to use Windows 10 without support poses security risks, while Linux offers a seamless upgrade process without new hardware requirements. Zorin OS can mimic the Windows interface and supports running Windows applications through Wine. Users must decide whether to invest in a new Windows 11 computer or explore Linux as a cost-saving alternative.

Patch Tuesday: Windows 10 end of life pain for IT departments

The conclusion of support for Windows 10 has led to the discovery of several zero-day vulnerabilities, including CVE-2025-24990, which involves a legacy device driver that Microsoft has removed. This driver, associated with the Agere Modem, has not been updated to meet modern security standards and is actively exploited by attackers. Microsoft opted to remove the driver rather than patch it, as patching could lead to system instability. Another vulnerability, CVE-2025-2884, relates to the Trusted Platform Module (TPM) 2.0, with Microsoft treating it as a zero-day despite its involvement with the Trusted Computing Group. Additionally, CVE-2025-49708, a flaw in the Microsoft Graphics Component, has a CVSS score of 9.9 and allows attackers to escape from a guest virtual machine to the host operating system, posing significant security risks.

Business security worries during the move to Windows 11?

Windows 11 will replace Windows 10 on October 14th and is designed with enhanced security features, making it the most secure operating system to date. It requires a motherboard and CPU that support Secure Boot to protect against malicious code during startup. The operating system integrates artificial intelligence within its Windows Security suite for improved threat detection and data protection. Key components include Microsoft Defender Antivirus, which offers real-time alerts and a centralized command center, and Windows Defender SmartScreen, which analyzes potential threats from websites and downloads. Additional security features include Windows Firewall, Bluetooth Protection, Secure Wi-Fi, and enhanced VPN functionality. Windows 11 also focuses on identity security with biometric access through Windows Hello and multifactor authentication via Microsoft Authenticator. The operating system is linked to Microsoft Accounts for centralized data management and includes a Find My Device feature for locating or locking stolen PCs. RCT Cloud is a recommended vendor for assistance with the Windows 11 upgrade, providing Microsoft licenses and support.

Zoho’s messaging app Arattai tops Apple App Store rankings after ministers lend it a boost

Chennai-based Zoho's instant messaging application, Arattai, has risen to the top of Apple's App Store rankings in the social media category in India. Launched in 2021, Arattai gained popularity due to endorsements from union minister Dharmendra Pradhan and IT minister Ashwini Vaishnaw, who praised its attributes and aligned it with the Swadeshi initiative. The app offers features similar to WhatsApp, such as text messaging, voice and video calls, media sharing, group chats for up to 1,000 members, stories, and broadcast channels. It is designed for users with low-end devices and those in areas with poor connectivity. Although it initially attracted users amid WhatsApp's privacy policy controversies, Arattai faces security challenges, as its text messages do not currently have end-to-end encryption, unlike WhatsApp. The app is also experiencing infrastructure issues due to an influx of new users, resulting in delays and functionality problems.

France bans WhatsApp, Telegram for government workers, mandates state messaging app

The French government has prohibited all public sector employees from using messaging apps like WhatsApp and Telegram for professional purposes, effective from September 1. They must transition to Tchap, a secure messaging service developed by the state, which features end-to-end encryption and stores data on French government servers. Prime Minister Francois Bayrou issued this directive on July 25, citing security concerns over foreign intelligence connections associated with consumer messaging applications. Tchap requires users to register with authorized government email domains and is intended to ensure confidentiality and optimal security for professional exchanges. Previous initiatives included a mandate for the use of Olvid, another encrypted messaging service, which can still be used by ministerial offices but Tchap is encouraged for state communications. Tchap faced security challenges during its beta launch in 2019, which were addressed. Telegram has also faced scrutiny in France for failing to comply with legal requests regarding user information.
