Often spread by malicious email or web pop-ups, ransomware are used by hackers to seize people’s data and then send threats to delete them unless a ransom is paid. The Wannacry attack a few months ago has victimized more than 200k Windows computers across the globe.
The hackers focused on targeting medical institutions, schools, finance and commerce businesses, government offices, and entertainment centers and movie theaters. The attacks revealed the lack of safety that organizations face even with their security systems.
Based on recent reports by IT security services in Australia, not only ordinary people, but even government agencies and big business fail to secure their systems and educate their staff about critical security practices. Being careful and vigilant when online might probably have stopped Wannacry from spreading in the first place.
Make Sure You Have Updated Software
Most security experts state that the malware that initiated this global cyber-attack, dubbed WannaCry, may have first infiltrated machines by luring people to download the malware via email. After the malware has infected the computer, the malicious code began to spread through a wide network of computers interconnected by the Windows file-sharing structure. Mac users, however, weren’t affected.
You can solve this problem by programming your Windows machines to automatically update your PC with the latest software.
Other types of malware may infect different OS, so it does not matter which device you have, as long as you regularly update your software you are in a way safer than those who do not.
Protect Your Computer With Anti-Virus Software
Aside from maintaining that your Windows is up-to-date with the newest security features, antivirus software can help stop malware from affecting your system. However, remember that with antivirus software, you should make sure that your antivirus is up-to-date, so it stops the latest malware on its tracks.
Also, be careful of fishy emails and pop-ups
Never click links inside suspicious emails. Do not click weird and dubious pop-ups and make sure that you close these windows.
Don’t Forget to Backup Your Data
Just in case a cyber-crook successfully infects your computer, you could save yourself by backing up your data in an external storage device such as a hard drive. By doing so, if a hacker did something sinister to your computer, you could just delete all the data from the PC and retrieve it from the back up.
Have a Security Strategy for Your Business
Companies should know the ideal time to apply such security updates to the system without affecting productivity.
IT services in Australia should always train and educate staff on how to spot suspicious emails.
If you have been a victim of such activities, the initial thing to do is disconnect your PC from the internet to make sure that your other devices are not affected. Next, report the crime to law enforcement and seek assistance from IT professionals who know what to do in data recovery so they can check the available options.
