Windows 11 Trick Bypasses Microsoft Account Requirement
Microsoft continues pushing users toward Microsoft Accounts in Windows 11 by removing workarounds like the BypassNRO.cmd script. However, a newly discovered method makes bypassing this restriction easier than ever — and it still works as of April 2025.
Discovered by user Wither OrNot and confirmed by BleepingComputer, this method lets you create a local account during installation without modifying the registry or using external scripts.
Here’s how it works:
During setup, when Windows 11 prompts “Let’s connect you to a network,” press Shift+F10 to open Command Prompt.
Run the following command:
start ms-cxh:localonlyThis opens a hidden local user setup screen, allowing you to bypass Microsoft Account requirements entirely.
Complete setup as normal — the system will continue using your new local account.
After setup, you can verify this under the Start menu → account icon — it’ll show a local user, not a connected MS account.

Critical RCE Vulnerability Found in Apache Parquet – CVE-2025-30065
A maximum severity remote code execution (RCE) vulnerability has been discovered in Apache Parquet, impacting all versions up to 1.15.0. Tracked as CVE-2025-30065, the flaw has received a CVSS v4 score of 10.0, the highest possible.
The issue stems from unsafe deserialization in the Parquet-Avro module, allowing attackers to execute arbitrary code when a crafted Parquet file is imported into a vulnerable system. While exploitation requires a user to process a malicious file, the widespread use of Parquet across big data platforms like Hadoop, AWS, Azure, and GCP increases the attack surface significantly.
Apache has patched the issue in version 1.15.1, and all users are urged to upgrade immediately. Organizations unable to upgrade should avoid untrusted files, validate inputs rigorously, and increase monitoring around systems processing Parquet data.
This vulnerability was responsibly disclosed by Amazon researcher Keyi Li and highlights the ongoing risks posed by untrusted data ingestion in analytics and data engineering environments.
No active exploitation has been observed yet, but the potential impact is severe. Admins and developers using Parquet in any form should treat this as a high-priority fix.

Gamaredon Hackers Target Western Military Mission in Ukraine Using Malicious USB Drives
The Russian state-linked APT group Gamaredon (aka Shuckworm) has been attributed to a February–March 2025 cyber attack targeting a foreign military mission based in Ukraine. According to Symantec researchers, initial access was gained via an infected removable drive containing a malicious shortcut file. Once inserted, the attack chain used mshta.exe to launch multiple payloads, including an info-stealing PowerShell malware known as GammaSteel.
The malware established C2 communications through legitimate services (e.g., Teletype, Telegram), propagated to other drives using malicious .lnk files, and executed reconnaissance scripts that collected screenshots, system details, antivirus status, and user documents. The final stage involved a more obfuscated GammaSteel variant that exfiltrated files with specific extensions from the Desktop and Documents folders.
Symantec noted an increase in Gamaredon’s sophistication—while still less advanced than other Russian actors, the group shows persistent improvement in evasion techniques, code obfuscation, and operational focus on Ukrainian targets.

EU's "ProtectEU" Plan Threatens End-to-End Encryption Across VPNs, Messaging Apps, and Secure Email Services
The EU Commission has launched ProtectEU, a broad internal security strategy aimed at giving law enforcement lawful access to encrypted communications. While still in its early stages, the proposal is already raising red flags across the cybersecurity industry for potentially undermining end-to-end encryption.
ProtectEU is part of a growing global trend where governments push for backdoors under the guise of national security. While aimed at combating crime, these proposals risk eroding digital privacy, weakening cybersecurity, and potentially driving privacy-focused services out of EU jurisdictions altogether.
Key Affected Services:
- VPN Providers: Proton, Mullvad, Surfshark, NordVPN, and others have expressed concern. Backdoors and data retention laws could force no-log VPNs to exit the EU market.
- Encrypted Messaging Apps: Platforms like Signal, WhatsApp, and Threema are primary targets for surveillance, as they use strong E2EE to protect user privacy.
- Secure Email Providers: Proton Mail and similar services could also be impacted due to their encrypted architecture.
- Secure File Sharing & VoIP Tools: Any service enabling private, encrypted communications or file transfers may be at risk if required to implement surveillance capabilities.
Industry Response:
- Proton: Warns weakening encryption would "make European security worse", not better.
- Mullvad: Criticizes ProtectEU as a rebrand of prior mass surveillance proposals ("Chat Control").
- NordVPN & Surfshark: Express cautious optimism but emphasize that privacy and security are inseparable.
- AdGuard VPN: Warns that enforced data retention would make no-log services "untenable".

4chan Hit by Major Breach: Alleged Hacker Leaks Source Code, Moderator Identities, and Disrupts Site
In mid-April 2025, the notorious imageboard 4chan suffered a significant cybersecurity incident that has left the site offline and raised serious concerns over its internal security. Multiple sources report that a hacker, allegedly with long-term access to the platform's backend, exfiltrated and leaked sensitive data including source code, moderation tools, and a full list of site moderators and janitors.
The breach was first hinted at when a previously defunct board on 4chan unexpectedly came back online, displaying the message “U GOT HACKED.” Following this, screenshots began circulating on social media and cybercrime forums, purportedly showing access to backend infrastructure, admin panels, and internal templates. Cybersecurity analyst Alon Gal noted that these materials appear legitimate, and at least one 4chan moderator, speaking anonymously, did not dispute their authenticity.
Further reporting claims the attacker had access to 4chan’s systems for over a year before initiating the leak. The incident not only exposed internal systems and personnel data but also disrupted the platform’s availability, with 4chan remaining inaccessible at the time of writing.
TechRadar and TechCrunch both received confirmation from individuals tied to 4chan’s moderation team, expressing concern that this breach may be worse than previous DDoS attacks or takedowns, given that the attacker may have had — or still has — full control over the platform’s infrastructure.
The incident has prompted a wave of reaction across rival forums and social platforms. Some users, particularly from historically antagonistic communities like 8chan and remnants of eBaum’s World, have openly celebrated what they’ve labeled as 4chan’s “downfall.”
4chan, known for minimal moderation and a culture steeped in anonymity and chaos, has long served as a hub for internet subcultures, memes, and coordinated online raids. However, it has also faced widespread criticism for hosting extreme content, including harassment, disinformation campaigns, and more recently, AI-generated explicit material.
