Zašifrované soubory - virus???  Vyřešeno

Příspěvekod maxixxx » 05 pro 2015 10:16

Dobrý den

dnes spustím PC a všechny soubory mám s příponou vvv a nejdou otevřít.
Na ploše přibyl soubor bmp zřejmě zpráva od pachatele.
(Myslím, že je v ní napsáno něco jako zaplat a dáme to do pořádku.

Co s tím?

Mám takto zakodované všechny fotky a videa za 15 let.

Díky za každou radu

Při troše štěstí by mohlo zabrat tohle i bez placení: https://www.csirt.cz/page/2261/

Screenshoty neukládej do zavirovatelného DOCX, ale v Malování je ulož jako JPG. Bude to bezpečnější a ten soubor vyjde menší.

Mimochodem. Jsou dva druhy lidí. Ti kteří zálohují, a ti kteří o nějaká data teprve přijdou.
Zálohování sice také stojí peníze, ale nakonec vyjde levněji, do budoucna... ;-)

Vše mám zálohovaný na googledisku (platím skoro 300 měsíčně za 1TB), ale tam se přeneslo šifrování.

Tohle není záloha, cloud je stejně "bezpečný" jako kdybys "zálohoval" na flashku nebo SSD, tedy vůbec! Zvlášť pokud se ti tam automaticky uploadují všechny změněné soubory a ihned přepíšou ty původní...

Záloha jsou nejméně tři kopie, na třech odlišných druzích médií, uložených ve třech geograficky vzdálených lokalitách. Z toho nejméně jedna nepřepisovatelná.

Takže můžeš mít všechno vypálené na DVD nejnižší možnou rychlostí, nahrané na externím harddisku uloženém v uzamykatelné skříni nebo trezoru, a pro jistotu jednu pracovní kopii v tom cloudu, abys měl všechno po ruce když potřebuješ. Je potřeba čas od času kontrolovat stav těch záznamů, nebo pro jistotu všechno zkopírovat ještě jednou.

Vyzkoušel jsi ten csirt.cz?

faraon

Máš pravdu, na cloudu zálohuju jen pro případ, že mně kleknou disky v PC.
S tímto sem opravdu nepočítal.

S tím csirt.cz nějak nevím co mám dělat

Koukám že online to už nefunguje, tak od nich musíš stáhnout Decryptolocker.exe a použít ho v příkazovém řádku. Parametr -h ti vypíše nápovědu. Víc ti k němu neřeknu, já ho v Linuxu nespustím ;-)

Zkopíruj k němu do adresáře nějakou zašifrovanou fotku a předhoď mu jí:

Kód: Vybrat vše

A uvidíme jestli si s tím poradí nebo je to nějaká nová šifra.
