In the case of the latest versions of ransomware in circulation, leading to an epidemic, the vehicle of the infection is always the same: an infected e-mail. To mislead the ignorant user, the email is disguised and appears to come from a known sender, sometimes it contains a message that exhorts the user to click on the attachment. Anyway, if the user opens the attachment, ransomware infects the PC into the file encryption process. UAE Technician is providing complete Ransomware Removal Services in Dubai.
How to defend yourself from ransomware | Ransomware Removal Services
It is pointless to try to defend itself by using traditional antivirus or antimalware programs, since, within hours of the first email spread of a new ransomware variant, these programs do not recognize threats to mail attachments. In the fight against ransomware, the use of antivirus and antimalware is considered to be completely bankrupt.
Beware of emails and their attachments
Sending infected emails, containing harmful attachments, represents the most widely used ransomware distribution technique. Among the new ransomware variants, some are delivered to the victim in the form of fake invoices, which are nothing but disguised malware. Other viruses are accurately masked in the form of communications from bank institutions or credit card providers, overdue payments, fees, information from well-known telephone operators, hosting service providers and so on. Of course, everything is designed to gain the trust of the user, causing him to do what the mail is asking him to do.
A good practice to avoid being infected is to pay attention to inbound e-mails, especially those that contain a file attached. It is therefore essential not to open the attachment for any reason, because as soon as you click on the file, ransomware is launched into the system and begins the inexorable encryption process. If you have any doubts regarding the email, which may also relate to alleged shipments in your favor, the advice is to contact the shipping company directly by calling customer service for clarification on the invoice and / or shipping. If the mails that run ransomware arrive in the inbox, you must be sure that you can recognize them. Without the credit of any message, even those that seem to come from known senders, you can look at the email, especially its header, from which you can go back to the IP address, often foreign and also fraudulent, which will confirm your presence of a possible threat.
Beware of fake links
In addition to the attachments, particular attention should also be paid to possible fake links within the mail. Links may seem authentic, as they point to regular web sites, but in reality they link to sites managed by hacker groups. In this case, it is critical to verify the legitimacy of the address via the HTML page: by using the Ctrl + U command, you access the source of the page, in this case the mail, from which you can check the addresses to which each link links in the mail. It should also be remembered that major companies use a HTTPS connection, which can be viewed in the browser address bar.
Several malware prefigures a second and false extension to the real one. We therefore recommend that you activate the Windows Extensions Display feature, while wondering about double extensions. Ex: invoice.pdf.exe (the harmless pdf format serves to deceive, while the .exe extension is related to ransomware).
Install a good antispam server side
Using an e-mail handler that leverages a good antispam and antivirus system can help limit the reception of infected messages sent by ransomware developers, which will be moved directly to the junk mail folder. Of course, it’s good to pay close attention to incoming mail even if you use a good antispam / antivirus system.
Disable the TEMP folder execution
When launching within the system, most ransomware copies the files that are essential for their operation in the Windows TEMP folder. By blocking the execution of files from this folder, you can automatically limit the damaging action of a large number of ransomware.
Beware of Shared Folders
Some of the latest cryptolocker variants are not just encrypting data in a single machine (PC), but they can also encrypt those inside your local network, so think about the Dropbox client, for example, whose content would be encrypted if the shared folder on your network is attacked by a ransomware. The same argument applies to files stored on other workstations connected to the same local network.
Do not overlook the backup tasks
To avoid losing all data in the event of an infection, it is good practice to back up your files regularly, even once a day, in order to save multiple versions of the same files and folders.
User Account Control
User Account Control is a good security method and minimizes the malicious impact of malware. The advice is to use a standard user account, or standard and non-administrative privileges, in order to limit the attack’s damage from ransomware to the files in use, circumscribing the infection. You should only use the administrator account if it is strictly necessary.
