Windows 11 February preview adds Sysmon, network speed test, and BitLocker improvements

Microsoft released the Windows 11 KB5077241 optional preview with 29 changes: improved BitLocker reliability; built-in network speed test for Ethernet, Wi‑Fi, and cellular; native Sysmon support (off by default) and auto Quick Machine Recovery on eligible Pro devices; plus UI and reliability tweaks (faster wake from sleep, smarter taskbar overflow, WebP desktop backgrounds, and RSAT on Arm64). It’s a non-security preview that can be installed via Settings > Windows Update or the Microsoft Update Catalog.

Cloud-stored BitLocker keys can be handed to law enforcement

Microsoft has confirmed that BitLocker recovery keys backed up in the cloud can be provided to law enforcement under a valid legal order, a situation highlighted by a Guam FBI case. To reduce this risk, users should avoid cloud backups and instead store the recovery key locally—on a USB drive or as a printed copy—and remove any cloud-stored copies; the piece also explains how to check BitLocker settings and how to back up the key safely.

Microsoft Gave FBI BitLocker Keys, Sparking Privacy Alarm

Microsoft reportedly provided BitLocker recovery keys to the FBI under a legal process, enabling access to encrypted drives and prompting concerns about who can access user data and under what safeguards. The disclosure underscores tensions between law-enforcement access and device security, renewing calls for greater transparency and tighter controls around enterprise encryption management.

Microsoft Enhances Windows Storage Speed with Hardware-Accelerated BitLocker

Microsoft acknowledges that enabling BitLocker on Windows 11 PCs with NVMe SSDs can cause a performance slowdown, especially during resource-intensive tasks like gaming and video editing, due to increased CPU usage for encryption. However, hardware-accelerated BitLocker, supported by upcoming CPUs and SoCs, offloads encryption tasks to dedicated hardware, significantly reducing CPU load and improving performance and battery life. Users can verify support via command line, and future updates will enable automatic use of hardware acceleration on compatible devices.

"ShrinkLocker Ransomware Exploits BitLocker to Encrypt Files"

A new ransomware strain called ShrinkLocker is exploiting Windows BitLocker to encrypt and steal files, primarily targeting government agencies and firms in manufacturing and pharmaceuticals. Unlike typical ransomware, ShrinkLocker does not drop a ransom note but instead uses email addresses as new boot partition labels for communication. It also deletes all BitLocker protectors, making recovery impossible without the attackers' key. The ransomware has affected organizations in Mexico, Indonesia, and Jordan.

"ShrinkLocker Ransomware Exploits BitLocker to Encrypt Data"

A new ransomware called ShrinkLocker uses Windows' BitLocker feature to encrypt victim data, targeting systems in Mexico, Indonesia, and Jordan. Discovered by Kaspersky, ShrinkLocker shrinks non-boot partitions and creates new primary partitions, then disables BitLocker protections and generates a complex encryption key. Kaspersky advises robust endpoint protection, minimal user privileges, and frequent offline backups to mitigate risks.

ShrinkLocker Ransomware Exploits Microsoft BitLocker for File Encryption

A new ransomware strain called ShrinkLocker uses Windows BitLocker to encrypt files by creating new boot partitions, targeting government entities and companies in the vaccine and manufacturing sectors. Written in VBScript, ShrinkLocker detects specific Windows versions and modifies registry entries to disable remote desktop connections and enable BitLocker encryption without a TPM. The malware deletes BitLocker protectors to prevent recovery and uses TryCloudflare to deliver encryption keys. Kaspersky advises secure storage of recovery keys and regular offline backups to mitigate such attacks.

"Raspberry Pi Pico: Breaking BitLocker Encryption in Seconds"

A security researcher demonstrated an exploit using a Raspberry Pi Pico and a custom PCB to break Microsoft's BitLocker drive encryption by sniffing the encryption key sent in plaintext from an external TPM chip to the laptop. While this exploit affects systems with discrete TPM chips, modern systems with firmware TPM modules integrated into the processor are not vulnerable. The exploit highlights the importance of understanding the type of TPM used in a system and the potential vulnerabilities associated with different TPM implementations.

"BitLocker Encryption Cracked in 43 Seconds with $4 Raspberry Pi Pico"

Security researcher Stacksmashing demonstrated in a YouTube video that BitLocker encryption in Windows OS can be cracked in just 43 seconds using a $4 Raspberry Pi Pico, due to a design flaw in devices with dedicated TPMs. By directly accessing the hardware and extracting the encryption keys stored in the computer's Trusted Platform Module (TPM) via the LPC bus, threat actors can bypass BitLocker's encryption. This raises concerns about existing encryption methodologies and the need for cybersecurity researchers to identify and fix potential security loopholes.
