Headlines worldwide are dominated by the latest ransomware attack, and the notorious Wannacry virus has affected computer systems across at least 150 countries, wreaking havoc on organizations, including the UK’s National Health Service. With the increase in these types of cyberattacks, understanding ransomware and taking steps to safeguard your business is more crucial than ever. But what exactly is ransomware? How can you secure your system against it, and what actions should you take if you become a victim of Wannacry or any other ransomware attack?
Ransomware is a form of malware that locks or encrypts your files, demanding a ransom to release your system. There are two primary types of ransomware: encryption ransomware, which encrypts your files, and lock screen ransomware, which freezes your screen. Both types render your computer unusable, with hackers typically demanding money, though they may also make other demands, such as personal information. While some ransomware attacks are highly targeted, many are simply designed to spread quickly and affect as many victims as possible.
The Wannacry malware stands out due to its ability to spread rapidly across a network once it infiltrates a single system. This self-replicating feature has made it particularly dangerous, affecting businesses globally and disrupting critical infrastructure.
How to Defend Your Business Against Ransomware
Preventing a ransomware attack starts with ensuring your computer systems are protected. The first step is to ensure your anti-virus protection is the best available and always up-to-date. It’s also vital to apply any patches or updates to your operating system, especially those addressing vulnerabilities. For example, the Wannacry virus exploits a flaw in older versions of Windows, but Microsoft has since released patches to address this issue. Always ensure that your systems are fully updated to minimize the risk.
Beyond the technical aspects, common sense plays a vital role in protecting your business. Never open email attachments or click on links from unknown senders, especially if they seem suspicious. Hackers often use these tactics to infiltrate your system. This precaution extends to social media, where phishing attempts and malicious links are common. It’s also important to ensure your staff is trained in these best practices to avoid mistakes that could compromise your entire network.
Cybercriminals work tirelessly to exploit vulnerabilities, so it’s essential to remain vigilant. While large organizations can afford to employ dedicated IT security teams, small and medium-sized businesses often lack such resources. If you’re hit with a ransomware attack, stay calm. Do not engage with the hackers, and under no circumstances should you pay the ransom. Paying does not guarantee that you’ll regain access to your system. These are criminals, and there’s no reason to trust that they will keep their word. Instead, contact a qualified IT security expert immediately to mitigate the damage.
Backing Up Your Data: The Ultimate Protection
One of the most effective ways to safeguard your business from ransomware is through regular, secure backups. Ensure your backup is stored in a separate location—preferably in the cloud or an external drive—so that it is not vulnerable to cybercriminals. Depending on the size of your business, the best backup options may vary, but the key is to store it in a secure, remote location, both physically and electronically. Regular backups ensure that, in the event of a ransomware attack, your most critical data is recoverable without needing to negotiate with hackers.
In the ever-evolving world of cybersecurity, staying proactive and prepared is the best defence against ransomware. By implementing strong security measures, educating your team, and ensuring you have a robust backup plan in place, you can help protect your business from the growing threat of ransomware.
