uz pri prvej bezpecnostnej diere par rokov dozadu bolo jasne ze UBNT nepatri na verejne svetove IP.

Znova sa to potvrdzuje.... Inak to chlapci zase pekne posrali...

Riesenie je jednoduche. Nemat ubnt na svetovych IP a ešte k tomu WEB na porte 80.

Na verejne IP nepatri takmer nic. Vsetko ma diery. Aj Cisco, aj Juniper, aj Windows, nikto nie je neomylny. UBNT je na tom stale s bezpecnostou o tri triedy lepsie nez bezny cinsky router/kamera/dvr/modem/atd, u takychto som uz zazil aj nacuvajuce ftp alebo telnet s otvorenym celym systemom, a heslom root/root ktore sa ani neda zmenit...

firmwary starsie ako tieto:
5.5.11 XM/TI
5.5.10u2 XW
5.6.2 XW/XM/TI
maju zdokumentovanu bezpecnosntu dieru (dlhsie ako pol roka) a vo vlastnom zaujme si ich treba ihned upgradovat prinajmensom na vyssieuvedene verzie. na deravych verziach staci na ziskanie plneho pristupu do zariadenia pristup k jeho webu a znalost spravneho postupu.

na uvedenych a vyssich verziach sa ubiquiti developerom nepodarilo zreprodukovat moznost nakazenia zariadenia wormom.

worm instaluje do zariadenia ssh kluc. ak ho neodstranis, pochopitelne ze zariadenie ostane dalej napadnutelne cez ssh.

Presne tak, ...preto to aj nadalej lezie cez SSH port. Virus uz ma ulozene kluce v zariadeni a teda nepotrebuje nadalej WEB pristup.

Prvotny atak ale ide cez WEB port a metodou php2 "post" vyuziva bezpecnostnu dieru v daka ktorej ulozi SSH kluce do zariadenia, tym ziska SSH pristup....dalej to poznate. (inak je to riadny fail!) asi taky isty ako skynet par rokov dozadu!

Akurat som nedopatral akym cinom sa to siri dalej? nevyskumali ste to niekto? Pouziva to UBNT discovery alebo len pinga ip v rovnakom subnete?

jezisi jasne ze sa stazuju pretoze updatom noveho FW sa virus NEODSTRANI!!!!!! Novy FW len zabranuje vzniku infekcie.

virus je nutne odstranit podla pokynov na fore! az potom robit upgrade.

Schytal to niekto? Udajne to taha veci z openwrt.org (treba ip adresy evidentne blokovat).

Kotol ako myslis treba firewall na input? - kazde ubnt zariadenie blokovat resp. upravit na INPUT? myslim ze tu by stacilo na brane na forwarde blokovat openwrt adresy....resp. cez staticke dns openwrt presmerovat....
