VIRY.CZ

Dobrý den,

předem bych Vám chtěl moc poděkovat za váš čas.

Dnes odpoledne mi přišla sms zpráva s 2FA ověřovacím kódem od gmailu, kterou jsem si nevyžádal. Měl jsem v tu chvíli na PC otevřený v chrome gmail účet a když jsem se podíval na obrazovku, myš se mi sama hýbala a někdo se hrabal v nastavení gmail účtu. Nestihl jsem ani zkontrolovat co přesně se dělo protože jsem v panice rychle Alt+F4 všechno, vypnul počítač a odpojil od sítě. Nikdy jsem se s ničím takovým nesetkal a nepodařilo se mi ani vygooglit podobnou zkušenost.
Pak mi došlo, že včera se mi odpojila synchronizace Chrome s google účtem, kterou jsem už včera večer neřešil, ale dnes ráno jsem ji obnovil zadáním hesla. Vše vypadalo naprosto normálně a nepojal jsem žádné podezření, že bych heslo zadával na phishingovou kopii stránky.

Ještě jednou děkuji za pomoc a přeji pohodový víkend.

S pozdravem

Jaro

Zdrzanie samozrejme nevadi, hlavne ked aj samotny sken trval niekolko hodin.

Poprosim o obidva nove logy z FRST.

Děkuji za rychlou odpověď a přikládám logy. Během toho co běžel FRST na mně vyskočil Malwerebytes s pár "Potentially Unwanted Program", tak do zipu přikládám i ten log z něj.

Přeji hezkou neděli

V Malwarebytes spusti rychly sken (cez modre tlacitko Sken na uvodnej obrazovke) a zmaz vsetky nalezy (presunut do karanteny). Po dokonceni posli opat log z tohto procesu mazania.

Pardon za zdrzanie.

Logy vyzeraju podla vsetkeho OK. Ako to momentalne vyzera s PC? Su nejake problemy?

Zdravím,

nic se neděje, děkuji mnohokrát za dosavadní pomoc!

Vypadá vše v pořádku. Měl by jste nějakou představu kam všude se s tím "backdorem" dostal? Když převzal kontrolu nad PC, tak se asi dá předpokládat, že mohl nepozorovaně krást data/informace/logovat stisky kláves/atp...?

Hezký víkend!
