Cum creezi și administrezi un VPN personal pe un router sau PC (folosind WireGuard sau OpenVPN)

Un VPN personal îți oferă securitate, confidențialitate și control total asupra traficului tău de internet, fără a depinde de servicii comerciale (care pot fi lente, costisitoare sau nesigure). Îți poți accesa rețeaua de acasă în siguranță de oriunde din lume, inclusiv fișierele din rețea, camerele de supraveghere sau interfața routerului.

Microsoft – CVE-2025-33053: Zero-Day WebDAV RCE Exploited by Stealth Falcon

On June 10th, Microsoft addressed a zero-day vulnerability — CVE-2025-33053, a Remote Code Execution (RCE) flaw in the WebDAV component of Windows. Researchers at Check Point reported that the APT group Stealth Falcon had actively exploited this flaw in targeted attacks.

Technical Details:

  • Attackers used malicious .url files that leveraged iediagcmd.exe (a signed Windows executable) to sideload malicious DLLs via trusted locations.

  • This chain led to the deployment of Horus Agent, a backdoor with advanced evasion and persistence tactics.

  • The vulnerability affects systems where WebDAV is enabled, especially those that interact with remote content or shared locations.

Impact & Recommendations:

  • Already exploited in the wild

  • Patch released via June Patch Tuesday – urgently apply all updates

  • Disable WebDAV where not required

  • Monitor event logs and audit execution from signed binaries in unusual directories.

Cum recuperezi datele șterse accidental de pe hard disk, stick USB sau card SD

Ai șters din greșeală un fișier important? Sau ai formatat un stick USB fără backup? Atunci când ștergi un fișier, acesta nu este șters complet imediat. Sistemul de operare doar „eliberează” spațiul, iar datele rămân acolo până când altceva le suprascrie. Așadar, cu cât acționezi mai repede, cu atât ai șanse mai mari de a recupera fișierul.
