What is Linkup Ransomware:
Threat Classification: Ransomware
Linkup Ransomware, Trojan-Ransom.Win32.Linkup or Council of Europe virus is a ransomware trojan, which targets computers running Windows operating system. Linkup Ransomware was first seen in January 2014. The infection might come from various sources – infected files from various P2P networks, torrents or other file sharing applications, email attachments etc.
Linkup Ransomware has a different approach compared with similar ransomware. Unlike its predecessors it would not lock you out completely of your computer or encrypt your files. What Linkup Ransomware does is to modify your DNS settings in order to block the internet access on your system, asking the user to pay. It can also utilize your PC`s processing power to turn your machine into a Bitcoin mining bot.
Once the infection is executed on your computer, it will inject itself deep into the system by modifying the registry in order to start with Windows on every boot. Linkup Ransomware will take over your system and will present a fake message stating that it`s issued by the Council of Europe, and your access to the internet is blocked. Furthermore, the bogus text says that you have to fill out your personal details in order to use the web. You will notice a fill-out form, whereas you`ll have to type your full name, address and contact phone number. The payment should be made through either Bitcoin or a pre-paid voucher – both are untraceable payment methods. The fake notification would look like the following or similar:
“The Provisions on the fight against sexual exploitation of children and child pornography on the Internet complies with the provisions of an EU Council decision from December 2003. It gives the police powers to arrest those who are responsible for child pornography, calls for the creation of the National Centre to combat child pornography on the internet and establishes that Internet Service Providers have a legal obligation to adopt a filtering system to avoid access to sites censored by the Centre.”
When you click on the “Confirm” button, you`ll be taken to another window, where you`ll need to confirm your details. For the verification process to be completed, you will also need to provide your credit card details. Linkup Ransomware claims that one euro cent will be withdrawn from your card.
Please note that these notifications are bogus and are used with the only purpose of making you believe that you are at risk and fooling you to submit your personal details.
Linkup Ransomware will not only block your internet access and lock your computer. It will also collect information that may be used to compromise you. Additionally your PC`s performance will decrease dramatically as your enslaved machine will be involved in Bitcoin mining (calculating long algorithms) utilizing all its power capabilities to mine Bitcoins.
The Ransomware may steal other relevant information, and send it over to the creators.
