How to Avoid Getting Scammed Online in 2026

The Qantas data breach highlights vulnerabilities in online information security. Regularly changing passwords every few months is recommended, and tools like Bitdefender’s Password Manager can help manage complex passwords. Users should be cautious of suspicious links and attachments, as hackers often use phishing tactics. Implementing two-factor authentication (2FA) adds an extra layer of security to accounts. Keeping devices updated is crucial for protecting against vulnerabilities. Investing in reliable antivirus software, such as Bitdefender Antivirus Plus or Bitdefender Ultimate Security, is essential for safeguarding personal data. Staying informed about cybersecurity measures is important to prevent data breaches.

Android 17 Beta 2 starts clamping down on apps that misuse accessibility services

Google has enhanced its Advanced Protection Mode with the rollout of Android 17 Beta 2, introducing stricter security measures that restrict non-accessibility applications from accessing the AccessibilityService API. This update prevents non-accessibility apps from obtaining accessibility permissions, revoking them from apps that already have them while the mode is active. Users cannot grant these permissions when Advanced Protection Mode is enabled. For example, the dynamicSpot app cannot receive necessary accessibility permissions under this mode. In contrast, the stable Android 16 QPR3 build allows dynamicSpot to function with Advanced Protection Mode activated. Applications that identify as accessibility tools, like screen readers, remain unaffected by this restriction. This change may cause compatibility issues for users who enable Advanced Protection Mode, offering a choice between enhanced security and access to certain applications.

No banking apps on your custom ROM? This new initiative could help.

UnifiedAttestation is a new initiative from Europe aimed at creating a free and open-source alternative to Google’s Play Integrity checks, which are essential for banking, financial, and government applications. Many of these applications currently rely on the Play Integrity API, which does not support custom ROMs or alternative Android forks, limiting access for users of these systems. The initiative is backed by smartphone manufacturer Volla and partners like Murena and iodé OS. UnifiedAttestation will be distributed under an Apache 2.0 license, allowing developers to adapt it, with Volla stating that integration requires only a few lines of code. However, the Graphene OS team has expressed concerns about the ethical implications of smartphone manufacturers determining which operating systems can use their applications, advocating for the regulation of the Play Integrity API instead.

How Your Android Apps Keep Talking — Even When You’re Not Using Them

When connecting to public Wi-Fi, using a VPN is essential as it encrypts traffic and creates a secure tunnel between the device and a remote server, keeping activities concealed from the local network. Android devices continuously communicate in the background, performing tasks such as updating emails and syncing notes, which increases data visibility on public networks. Public Wi-Fi has become common due to remote work and shared spaces, leading to increased privacy risks as smartphones now store sensitive information like banking apps and personal photos. Users are encouraged to adopt simple security habits, including using a VPN when connecting to public networks. Android devices are always connected, making network-level protection important to safeguard background communications.

How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.

Windows 11 shutdown bug: Microsoft confirms KB5073455 issue

Microsoft has acknowledged a shutdown issue affecting Windows 11 Enterprise and IoT editions after the January 13, 2026 security update (KB5073455) for version 23H2, which prevents affected systems from shutting down properly, causing them to either hibernate or restart instead. The problem is linked to the System Guard Secure Launch feature and does not affect Windows 11 Home and Pro editions. A temporary workaround involves using the command "shutdown /s /t 0" in an elevated Command Prompt to force a shutdown, but there is no workaround for hibernation functionality. Microsoft is working on a resolution and suggests that enterprise IT administrators consider pausing the deployment of the update on unaffected devices.

Microsoft’s New Update Deadline—550 Million Windows Users Must Act

Microsoft has phased out Windows 10, with a deadline of October 14 now passed, leaving approximately 550 million users navigating the transition to Windows 11 amidst rising cyber threats. Windows 10 usage has declined from 880 million in January. Microsoft offers an Extended Security Update (ESU) option for users needing more time to migrate, which provides security updates until October 13, 2026, for enrolled users. Business users have a three-year extended support period, while consumers have a 12-month grace period post-October if enrolled in ESU. The November update addressing zero-day threats is only available to ESU enrollees. There are no contingency plans for users who remain on Windows 10, and uncertainty exists regarding how many users have enrolled in ESU or have eligible devices for Windows 11 upgrades. Users must act before next October to purchase new PCs if needed.
