It's a piece of ransomware that encrypts the Master Boot Record — the guts of a Windows hard drive — to prevent a computer from starting up properly.
勒索软件通过加密主引导记录即Windows硬盘驱动器的重要部分来阻止计算机正常启动。
There's also a second piece of ransomware that encrypts various files on the machine if the Master Boot Record attack fails.
如果攻击主引导记录失败,则有第二个勒索软件加密电脑上的各类文件。
And there's a fourth component that steals usernames and passwords from infected machines, possibly only so it can infect more machines.
此外,第四个组件可以从已感染的电脑中窃取用户名和密码,这可能是为了感染更多电脑。
Who is at risk?
哪些电脑有感染风险?
The silver lining is that properly patched Windows systems that are not connected to enterprise networks, such as home computers, are at little risk of being infected by the Petya worm — at least for now. If you use a home computer to connect to a corporate VPN, however, you greatly increase the chances of your home network becoming infected.
还算幸运的是,未连接到企业网络并打过正确补丁的Windows系统,比如家用电脑几乎不会受到Petya蠕虫感染,至少目前不会。但是,假如你用家用电脑连接到企业VPN,则会大大增加家庭网络受感染的几率。
