Netflix series Zero Day highlights real cyber threats
The potential for zero-day vulnerabilities to instigate nationwide cyberattacks is explored in Netflix's latest series, "Zero Day".
While the story may seem far-fetched to some viewers, cybersecurity experts emphasise that the risks depicted are very much a real concern in today's interconnected world.
Avast, a cybersecurity brand under Gen, asserts the significance of zero-day vulnerabilities and the possible damage they could inflict if exploited.
These vulnerabilities, which are unknown to the software developer at the time they are discovered in the wild by attackers, can be used to gain unauthorised access to systems and data. The attacks remain effective until the software developer issues a patch.
Cyber experts recommend several strategies to mitigate the risk. Ensuring that devices and software are continuously updated is a key preventive measure. Security patches issued by vendors in regular updates should be installed promptly to neutralise any identified threats. "Many zero-day attacks only succeed until a fix is available – once patched, the threat is neutralised," said the cyber professionals from Avast. Automatic updates are advised as they ensure timely installation of crucial patches.
Using reliable security software is also advocated. Advanced security solutions can identify suspicious behaviour and potentially new threats, extending protection beyond mere known virus signatures.
"A good security solution can sometimes detect suspicious behaviour even from new, unknown threats," a representative noted. Maintaining up-to-date security software and incorporating firewalls helps to build a robust defence mechanism.
Phishing remains a prevalent method for attackers to deploy zero-day exploits. Caution is advised when dealing with unsolicited communications that might direct recipients to malicious websites or trick them into downloading harmful software.
"A convincing scam email might lure you to a malicious website that quietly uses a zero-day to infect your computer," explained the experts. Verifying the authenticity of emails and messages before acting on them is essential.
Practising standard cybersecurity protocols can limit exposure to threats.
This includes avoiding downloads from unverified sources and being cautious about unexpected attachments or requests to enable macros in documents. Employing strong, unique passwords and enabling two-factor authentication (2FA) adds layers of protection.
"Good habits act like a safety net, catching a lot of threats before they can ever execute," stated Avast.
Regularly backing up data provides a safety net in the event of an attack. While it does not prevent the occurrence of a security breach, having backups ensures data can be restored without ransom demands or data loss. "If a zero-day powered ransomware or wiper malware strikes, having recent backups of your important files means you can restore your system," advised the cybersecurity experts.
"Zero Day" provides a dramatic portrayal of cyber threats, but it also raises awareness and underlines the importance of vigilance and proactive measures in cybersecurity. In a world where the landscape of cyber threats is rapidly evolving, such precautions are not just advisable but necessary.
