snazia sa ma hacknut?

Príspevok od používateľa molnart »

Znie to blbo, ale viete mi vysvetlit preco sa snazia v kuse prihlasit do mojho routra z cinskych ip adries? Hovoria vam nieco tie cisla portov ze o co sa snazia? (napr. pripojit sa na RDP ci daco?)

Podla niektorych zaznamov (napr. Jan 12 19:02:12 E3000 authpriv.info dropbear[12360]: Exit before auth: Incompatible remote version 'SSH-1.5-Nmap-SSH1-Hostkey') to tak vyzera ze neskusaju iba heslo ale aj nejake ssh kluce. Myslite ze mi bezi nieco v sieti co niekomu leakuje ze mam v kompe nieco zaujimave? vypol som access s wanu pre web aj ssh, portforwarding mam nastaveny len pre torrenty.

Možno by pomohlo napísať aký používaš router, resp. systém v ňom. Ja som mal niečo podobné na OpenWRT, kde som mal vypnutý FW.

nepomohlo - su to uplne normalne štichpróby zo zavirenych masin na internete, najdes to na kazdej verejnej adrese. Neurobis s tym nic.

Tie porty ktore su tam ukazane su zdrojove porty na druhej strane - tebe sa snazia pripojit na router zrejme na SSH port a skusaju uzivatelov doradu z nejakeho slovnika.

len ma zaujima podla coho zo 4 miliard IPv4 adries zacali hackovat prave moju, nieco ich tam muselo nalakat. ked som videl tie cinske IP-cka tak hned mi napadla xiaomi appka ktora im moze nieco vysielat. pripadne niekto zaveseny na torrentoch fishuje adresy a potom takymto bruteforcom sa do nich snazi naburat. a este otazka co by ziskali kebyze sa dostanu cez ssh do routra? zaujimave data su az v kompoch a cez router dostat malware to windowsackeho alebo androidackeho systemu asi nie je len tak, ci? jedine by sa vedeli dostat mozno k fileshareom vo vnutornej sieti.

Tak tak. A je divné že tam nemáš žiadny FW... ja mám OpenWRT, resp. PandoraBox na Xiaomi Mini a mám to isté ale pozapnutí FW už v logoch nić nemám.
