Ransomware is now a Huge Problem for the Industry
No matter if you call it cyber bullying or just old-fashioned blackmail, the truth is that it is so tempting to pay someone just to get control of your PC back. We all should back up daily, and with good intentions we do that less regularly as we should do. The one time you are late in backing up, could be the time the hackers blackmail you.
We hear more often the word Ransomware. More and more reports of people being affect, but not many actually report it. Maybe this is because they are embarrassed, don’t want some information in their PC to become public, or what’s the point?
According to Trend Micro, this is the definition of Ransomware.
Ransomware is a type of malware that prevents or limits users from accessing their system. This type of malware forces its victims to pay the ransom through certain online payment methods in order to grant access to their systems, or to get their data back. Some ransomware encrypts files (called Cryptolocker). Other ransomware use TOR to hide C&C communications (called CTB Locker).
The ransom prices vary, ranging from $USD 24 to more than $USD 600, or even its bitcoin equivalent. It is important to note, however, that paying for the ransom does not guarantee that users can eventually access the infected system.
Users may encounter this threat through a variety of means. Ransomware can be downloaded by unwitting users by visiting malicious or compromised websites. It can also arrive as a payload, either dropped or downloaded by other malware. Some ransomware are delivered as attachments to spammed email.
Once executed in the system, a ransomware can either (1) lock the computer screen or (2) encrypt predetermined files with a password. In the first scenario, a ransomware shows a full-screen image or notification, which prevents victims from using their system. This also shows the instructions on how users can pay for the ransom. The second type of ransomware locks files like documents, spreadsheets and other important files.
From Keep Browser Safe
Ransomware is a latest way invented by the group of hackers to generate revenue by hijacking computers. This type of infection can comes into your computer through any of the way like via e-mail that contains malicious attachment or a malicious website. Ransomware is actually a type of malware but completely different from others malwares like adware, browser hijacker etc. After entering into your computer it never hide itself like other type of malware but it start encrypting your precious files like photos, videos, documents, and display a genuine looking electronic ransom note. Note may be related to the FBI and other criminal controlling department. And to restore or free all the encrypted files you have to pay ransom.
How Ransomware Spreads.
Computer virus can use lots of way to make your PC infected but ransomware is usually comes with installation files camouflaged as official software updates. They are promoted as updates for Java, Flash Player and Adobe Acrobat. You will get such type of messages if you opened subversive websites such as torrent sites.
