Why identity theft protection now matters just as much as antivirus

Cybercrime has shifted focus from targeting individual devices to stealing credentials and personal data for identity theft. In 2024, consumer losses due to fraud reached billion, a 25% increase from the previous year, with over a million identity theft reports filed. Stolen passwords and session cookies are central to most breaches, making credential theft the primary enabler of attacks. Password reuse is a significant vulnerability, with 65% of individuals reusing passwords, leading to increased risk of account takeovers through credential stuffing. Bitdefender offers features like Scam Protection Pro, which protects against fraud across email, chat, and SMS, and identity monitoring in Ultimate Security that alerts users to data leaks in real-time. In 2025, researchers identified approximately 2 billion unique leaked credentials, emphasizing the need for identity protection alongside traditional antivirus solutions.

OEMs reveal Windows 11 Secure Boot fix after deadline passes, here’s how to update your PC

Major PC manufacturers, including HP, Dell, ASUS, Lenovo, MSI, Acer, Samsung, LG, and Microsoft’s Surface division, have provided guidance on transitioning to new Secure Boot certificates as the expiration of Microsoft’s 2011 certificates approaches. The expiration will occur in three phases: Microsoft Corporation KEK CA 2011 expired on June 24, 2026; Microsoft UEFI CA 2011 expired on June 27, 2026; and Microsoft Windows Production PCA 2011 is set to expire on October 19, 2026. Microsoft has begun rolling out replacement certificates through Windows Update, contingent on OEMs providing compatible BIOS updates. ASUS offers detailed documentation for both consumer and commercial devices, confirming that most users will receive updates automatically. Lenovo provides direct download links for BIOS updates organized by product family and specifies which products will not receive updates. Dell's support article covers its entire product lineup, noting that devices with an End of Service Life before January 1, 2026, will not receive updates. HP outlines a dual-track approach for updates, with specific timelines for commercial PCs. Microsoft's Surface devices receive updates directly from Microsoft, while MSI categorizes guidance based on processor generation for its laptops. Acer emphasizes backing up the BitLocker recovery key and provides a model table for confirmed BIOS release dates. Samsung confirms that all PCs running Windows 10 or 11 will function normally post-expiration, but security updates will cease. LG has released a guide for checking BIOS updates for its PCs. To verify if a PC has the 2023 certificates, users can check the Secure Boot section in Windows Security. A green checkmark indicates successful application, while yellow or red icons indicate pending updates or incompatibility. Microsoft has pushed the certificates to all eligible devices as of June 2026.

Windows 11 Secure Boot update released to all, hours ahead of expiry

Microsoft has begun rolling out the Secure Boot 2023 certificate update to eligible Windows 11 and Windows 10 PCs ahead of the expiration of the Microsoft Corporation KEK CA 2011 on June 24, 2026. This update enhances device targeting data for automatic Secure Boot certificate updates. Secure Boot is a firmware-level security feature that verifies digital signatures of boot components to prevent rootkits and bootkits. The certificates for Secure Boot were first issued in 2011, with subsequent expirations for related certificates occurring in June and October 2026. Users can check their Secure Boot certificate status through the Windows Security app or System Information. If a PC does not receive the update, it will still boot normally but will lose the ability to receive future boot-level security updates. Multiple restarts after updates are expected due to the Secure Boot certificate process. A new folder, C:WindowsSecureBoot, is not malware but is used for staging cryptographic certificate files. Windows 10 users enrolled in the Extended Security Updates program will also receive the Secure Boot update, while those not enrolled will not. The expiration of the KEK CA 2011 means Microsoft will not be able to sign new Secure Boot revocation payloads using the old key, but existing signed payloads will remain functional.

Windows 11 Secure Boot update released to all, hours ahead of expiry

Microsoft has begun rolling out the Secure Boot 2023 certificate update for eligible Windows 11 and Windows 10 PCs ahead of the expiration of the original certificates on June 24, 2026. The update includes additional device targeting data to increase coverage for automatic updates. Devices receive the new certificates after demonstrating successful update signals. The original Secure Boot certificates were issued in 2011, with expiration dates set for June 24, 2026, June 27, 2026, and October 19, 2026. Microsoft has been distributing replacement 2023 certificates since 2024, with the June 2026 update expanding eligible devices significantly. Users can check their Secure Boot status through the Windows Security app or System Information. If a PC did not receive the update, it will still function normally but may not receive future boot-level security updates. Multiple restarts after updates are expected behavior, and the SecureBoot folder in Windows is not malware. Windows 10 users in the Extended Security Updates program are also receiving the Secure Boot update. The expiration of the Microsoft Corporation KEK CA 2011 on June 24 means no new Secure Boot revocation payloads can be signed with the old key, but existing signed payloads will continue to function.

Microsoft reveals how to verify Windows 11’s Secure Boot update, what to do if your PC missed it

The expiration of Microsoft's Secure Boot 2011 certificates on June 24 will not prevent older Windows PCs from booting, as confirmed by Microsoft. Devices will continue to operate normally, but they will miss future boot-level security updates, including updates to the Windows Boot Manager and mitigations for newly identified vulnerabilities. The ability to receive the Secure Boot 2023 update depends on the device firmware's compatibility, with many manufacturers, including Dell, HP, Lenovo, and ASUS, having cutoffs for BIOS updates based on the device's End of Service Life. Older PCs using Legacy BIOS or Compatibility Support Module (CSM) mode do not utilize UEFI Secure Boot, making the update irrelevant. Users running Windows 11 on unsupported hardware may have Secure Boot disabled or improperly configured. Without the 2023 certificates, devices cannot receive future revocation updates to the Secure Boot DBX, which lists compromised bootloaders. Users on Windows 10 with supported OEMs may receive the update if a compatible BIOS is available, while those on older PCs without updates can continue using their devices but will lack future security updates. The Secure Boot status can be checked through the Windows Security app, with color-coded badges indicating the status of the certificates.

Microsoft released the Windows 11 Secure Boot update for all PCs, how to verify yours

Microsoft has expanded the rollout of the Secure Boot 2023 certificate update to more Windows 11 and Windows 10 devices with the June 2026 Patch Tuesday update (KB5094126). This update aims to ensure that most supported consumer PCs are classified as high confidence, meaning necessary certificates are either installed or will be applied automatically. Secure Boot is a firmware security feature that verifies the software attempting to load during the startup process, blocking unauthorized software. The certificates supporting Secure Boot, issued in 2011, are expiring in stages starting June 24, 2026, prompting Microsoft to deploy replacement certificates. Most home users do not need to take manual action as the updates will occur automatically via Windows Update. Users can check their Secure Boot certificate status in the Windows Security app. A yellow warning indicates pending compatibility data, while a red alert suggests a firmware incompatibility requiring a BIOS update. Multiple reboots during the update process are normal, and a new SecureBoot folder in Windows is for staging cryptographic files. Older PCs may experience longer update times, and some may not receive updates due to firmware issues. HP users should check for BIOS updates if encountering BitLocker recovery loops. IT administrators should monitor device classifications and manually initiate updates for devices not in the high confidence category. Devices with Secure Boot disabled cannot receive updates, leaving them vulnerable. The expiration of the Microsoft Corporation KEK CA 2011 certificate on June 24 does not immediately affect device functionality, but it limits Microsoft's ability to sign new bootkit blacklist updates.
