Cyber attacks have always been a problem for Internet users, but their increasing presence and sophistication affect both home and business computers, posing a threat to corporate data. Personal information, accounts or finances are just a few of the areas that are harmed by malicious software that comes from different channels. We explain how to prevent the spread of malware by email, as it is the mechanism most used by cybercriminals because of its easy implementation.
Fighting malware at Home
Ignorance and overconfidence are the weapons used by black hat hackers to spread malware emails, so you should be aware of every mail received and look at some key points. First, examine the subject to determine if the text is doubtful, is in another language or was written in an unknown language. In case the sender is a company, you must match your name with the email address that sends it.
Also, do not open attachments if you do not recognize the extension, usually using slim and doom that corresponds to Office documents to run encryption programs. The result is the loss of your documents and the request for an economic reward to recover them. Of course, any personal data such as users or passwords should not be provided under any circumstances, especially if it is banking information as you should know.
Fighting malware while working in an enterprise/office
The number of people who have company email addresses the propagation of threats. It is desirable to audit documents shared with employees, which are sent to customers and those that are received. Each worker should respect the cyber security protocols, such as the elaboration of a daily backup of documents in the corresponding cases or the systematic examination of the state of the system through antivirus.
An applicable safety measure is to restrict the type of document manipulated by each department so that an infection does not reach all areas and can be contained. On the other hand, the daily use of the mobile to control most aspects of our life – including work – puts at risk the integrity of the company because the type of malware is different in computers and mobile. Most Smartphone users do not have antivirus installed on their device, so an action protocol to check the company’s emails from the mobile is one of the best security ideas you can take.
