Synology Diskstation NASy čelí útokům

Známá a oblíbená zařízení NAS Diskstation od společnosti Synology jsou vystaveny náporu útoků, kdy se útočníci pokoušejí přihlásit na systémový účet ADMIN. Zařízení musí být samozřejmě připojené k internetu.

Jde o útok typu Brute Force (prolomení hesla hrubou silou = zkouší se všechny možné kombinace hesel, dokud nedojde k jeho uhodnutí) a tento útok je nebezpečný i z toho hlediska, že k přihlášení dochází ze stovek IP adres najednou. Tím se obchází možnost tyto adresy zablokovat, což Synology Diskstation umí. Protože se ale každá z řady adres použije za dobu více jak 10 minut, k jejímu zablokování nedochází. Standardní nastavení v centru zabezpečení zablokuje IP adresu po pěti neúspěšných pokusech o přihlášení během deseti minut. Doporučujeme nastavit limit času i na 600 minut, aby se tak zablokovaly adresy, přistupující úmyslně s menší četností.

Na svém Synology si vytvořte další účet s administrátorskými právy, kdyby došlo k zablokování účtu ADMIN opakovanými pokusy o prolomení hesla. Současně pro všechny účty použijte silná hesla, ideální je kombinace písmen, čísel a speciálních znaků (například Tajn3-h3slo). Takováto hesla je obtížné prolomit hrubou silou. Krátká nebo slovníková hesla (běžná slova nebo často se vyskytující hesla typu 123456 nebo qwertz) jsou prolomena obvykle velmi rychle.

Můžete i blokovat již známé IP adresy, ze kterých probíhají útoky. Je to zřejmě botnet (síť zneužitých počítačů, o kterých obvykle ani majitelé netuší, že je někdo využívá k útokům) a proto se IP adresy mohou často měnit. V zařízení otevřete Ovládací panel, běžte do Zabezpečení, na záložce Účet klikněte na tlačítko Seznam povolených/blokovaných položek, vyberte Seznam blokování, kde je vedle tlačítka Vytvořit malá šipka, po jejímž rozkliknutí vyberte Importovat seznam IP adres. Stáhněte si TENTO seznam adres jako textový soubor a ten v uvedeném menu naimportujte. Tím budou rázem blokované dosud známé adresy, ze kterých probíhají útoky.
