What is Roracoon Malware?
Roracoon malware is categorized as a dangerous and destructive computer Trojan virus. It sneaks into the system without user permission and can cause severe damage and various problems to the system.
A Trojan is a dangerous computer program that seeks backdoor entries to attack the system and other computers in the network. Its mode of infiltration is via emails containing tainted attachments. After these tainted attachments are opened a hidden code is activated that downloads more files for full activation of the threat.
Trojans target the data stored on the hard drive. It mainly attacks the OS loader and user specific files. Once these files are corrupted the system tasks start to behave erratically. Trojans are used by cyber criminals to gain access to the system and steal user information.
Roracoon malware enters the system using these methods;
- Phishing emails that contain attachments – Phishing emails contain bait customized in such a way that the user is lured into opening these emails. These emails contain attached files that are opened in different programs. Once they are enabled for editing, these files execute a hidden code that activates the malicious program.
- Clicking on unsecured links– While browsing the user may click on links that may not be secure and can lead to malicious files being downloaded on the system.
- Fake system or program updates – Some websites display that a certain program needs update but it is a fake message and the user should avoid clicking it.
- Peer to peer network file transfers – Transferring files over a network can propagate the infection from one system to another.
- Connecting third party flash drives – External flash drives that contain infected files may cause the transfer of malware into the system.
Roracoon Malware – Threat Behavior
Roracoon malware infiltrates the system secretly. The first change that it makes in the system is to lower the system security settings by deactivating the various anti-virus tools, firewall and task manager.
After it has lowered the system security, it starts creating junk files and clogs the system space. Without the required CPU Memory, the legitimate system programs fail to perform their assigned tasks.
Roracoon Trojan virus also creates several fake Dllhost.exe processes which consume system memory and slows down the CPU’s processing speed. This leads to frequent system crashes, boot errors and hard drive failures.
It targets the following web browsers namely Google Chrome, Mozilla Firefox and Internet Explorer. Roracoon malware lowers the browser security setting and starts displays annoying pop-ups and banner ads, and causes page redirects without user approval.
The Roracoon malware secretly tracks user activities. It steals their vital and confidential data containing username, passwords, bank account & card details, and other personal information. This information can be then sold by hackers to a third party for money. Once this information lands in the hands of these malicious persons, they can use it to extort money or ruin the public image of the user.
Roracoon malware installs other variants of itself in the system by replicating itself. It also installs other dangerous virus and malware in the system which can cause the system to lag and freeze. These new threats can mess up the system entries and create more dangerous problems that are harder to track and remove.
