The primary purpose of Gameover ZeuS was banking fraud. This reduced the traffic traveling in and out of the server and made the C&C harder to trace. The system used a Peer-to-Peer architecture for communication with the C&C server.

It included more than 1 million zombie computers. The Gameover ZeuS botnet was created and controlled by Evgeniy Mikhailovich Bogachev, a Russian hacker. Spam filters on most email systems divert emails from one IP address in bulk by sending those large mailouts from lots of different locations, the botnet ducks that block. They are also used for spam email campaigns. Typically, these legions of computers are used in DDoS attacks, where many computers simultaneously make a connection request to a Web server, overwhelming it. So, hackers invented botnets in which each computer just attacks a target once.

Defense mechanisms in cybersecurity software can read the IP address of an attacker and block it. Some botnets control hundreds of thousands of private computers, and other control IoT devices, such as security cameras. The purpose of a botnet is to spread a task between many computers. In most cases, those companies don’t even realize that their devices are working for other people. The computers in the botnet are called “ zombies.” They aren’t entirely controlled by the hackers and continue to operate as usual. The active mechanism on the captured computer can open a connection and scan the remote server for instructions – that host is called the “ command and control” (C&C) server. During its period of operation, it attacked about 500,000 computers.Ī botnet is a group of infected computers controlled from a central server over the Internet.

Men datorn kan hämtas till en lokal tekniker för att kolla om det inte finns rester av viruset på datorn, samt för att se om någonting kan eventuellt göras åt krypteringen. Viruset brukar förstöra sig själv, så att det kommer inte att kryptera fler filer.ĭet är ingen idé att köra en systemåterställning av datorn eller likadant. Ibland upptäcks de inte alls eller bara efter att kryptering är klar. Det är svårt för antivirusprogrammen att upptäcka sådana Ransomware virus, eftersom de blir ständigt omförpackade. Det skadliga programmet visar sedan ett meddelande som erbjuder att dekryptera filerna så länge som man betalar en viss avgift. När viruset aktiveras, krypterar det vissa typer av filer. Detta virus och dess varianter brukar vara riktade mot småföretag och sprids oftast via phishing och infekterade e-postbilagor. Såvitt jag förstår har vissa filer krypterats på datorn och det går ej att öppna dem längre.ĭet verkar som att din dator är infekterad med CryptoLocker (eller Cryptowall) viruset.
