Ransomware: it is one of the biggest digital threats to individuals and organizations. Cybercriminals use it to get hold of sensitive data and encrypt it so you can no longer access it. They then demand a ransom in exchange for decrypting the data. But what is it all about and how can you prevent it? To protect yourself, your employees and your business, we tell you what ransomware is, how attacks take place and how to prevent ransomware.
How does ransomware work?
Ransomware is a form of malware that disrupts computer systems, collates sensitive data or gains access to private systems. The software installs itself on computers, networks and files. Once the data is encrypted, a message is displayed in which hackers demand that the user pay a fee to recover the encrypted files. Payment is demanded mainly in cryptocurrencies, such as Bitcoins, to conceal the hackers' identity.
The risks of ransomware
Ransomware can do a lot of damage to an individual or organization. Risks of ransomware can include:
- Release of sensitive personal or business data
- Infliction of financial damage
- Business disruptions incurring major financial consequences
- Reputational damage to yourself, employees and/or the company
How do ransomware attacks take place?
Because hackers are becoming increasingly savvy, a ransomware attack isn't immediately noticeable. In a previous article, we explained how cybercrime can be identified. Be alert and aware of how hackers operate. Some ways in which you can become a victim of ransomware are:
Phishing emails
One of the most common methods to spread ransomware is a phishing email. Hackers send these emails to potential victims, often disguised as legitimate messages. By clicking on links or opening attachments in these emails, the ransomware is installed on the user's system. Read on to learn how to avoid phishing.
Software vulnerabilities
Hackers are constantly looking for vulnerabilities in software, including operating systems and applications. Once they discover a vulnerability, they can exploit it. This is done through malicious coding. Stay ahead of hackers, and make sure your software is always up-to-date. This reduces the vulnerability of your software.
Use of unsafe websites and downloads
Hackers can also strike through malicious ads or links on insecure websites. Users who click on these links or download files consequently install ransomware on their systems. A secure website can be recognised by 'https' in your browser's address bar or by a secure lock icon. If you don't see this, chances are the website isn't secure.
Network security vulnerabilities
Occasionally, hackers can find weaknesses in an organization's network security, such as poorly configured firewalls or unpatched servers. A patch is a small piece of software used by the publisher to fix bugs. If the software doesn't include a patch, you are at risk of network vulnerabilities. By exploiting these vulnerabilities, they can gain access to the network and install ransomware. This can be done on multiple systems simultaneously.
Tips to prevent ransomware
Although ransomware is a threat, you can protect yourself with the following measures:
Use strong passwords
Use complex and unique passwords for all your accounts and avoid using the same passwords across multiple accounts. Read more about an ironclad password here.
Be alert to phishing attempts. Handle email attachments and links with care
Do not open attachments or click on links in emails from unknown senders.
Use anti-virus software
Install and regularly update antivirus software on all your devices. This helps detect and remove malware.
Updating software
Make sure you regularly update your software. Updates keep your software secure and properly functioning; software that is not updated may contain vulnerabilities.
