Zdalny exploit na MS17-010 – dostępny w Metasploit

16 maja 2017, 20:24 | W biegu | komentarze 3

Kto jeszcze nie załatał swoich Windowsów, radzę się pospieszyć. Dostępny jest już publicznie exploit na podatność MS17-010 (zdalne otrzymanie pełnych uprawnień na Windowsach – przez protokół SMBv1). Przypominam to błąd wykorzystywany przez ransomware WannaCrypt / Wana Decrypt0r 2.0 / Wanacry.

Użycie exploita nie wymaga jakiejś wielkiej wiedzy – po prostu ognia:
