How you or your company could be vulnerable to a cyber attack

Could you or your company be the victim of a cyber attack? These notorious attacks don’t just happen to Colonial Pipeline, Facebook and cryptocurrency platforms. They happen to vulnerable midsize businesses, startups, and even people like you. Just as the attack on the Colonial Pipeline affected 50 million customersthe Facebook breach exposed the data of half a billion customers, and the BadgerDAO breach cost DeFi platform users $120 million, a cyberattack against you or your company could be debilitating, and not just for your finances and your clients’ finances, but also your reputation and therefore your future prospects for success.

Ways you and your business could be vulnerable to attack include: smart devices, AWS or other centralized third-party cloud services, bad code issues, phishing scams, and data hijacking attacks There are many others, but let’s take a look at these vulnerabilities to get an overview of the dangers they present and the best ways to prevent them.

The era of IoT (internet of things) is upon us, connecting our lives quickly and conveniently. Along with these conveniences, however, come inherent security risks. Smart devices, including refrigerators and cars, are connected to Wi-Fi and can make personally identifiable information vulnerable to cyber attacks.

Wi-Fi today is secured with the WPA2 (Wi-Fi Protected Access 2), which, while considered more secure than its predecessors and classified as government-grade security, is considered vulnerable due to a flaw discovered in 2017. Through a “KRACK“, or rekey attack, a cyber attacker can read encrypted data that travels between smart devices and access points. Personal information, including passwords, credit card numbers, private messages, and photos, can be accessed through of this method. The attacker may even be able to add and manipulate data on a Wi-Fi connected device. Ransomware or other malware could be attached to a site using KRACK.

If possible, refrain from using public Wi-Fi, as this is always a risk. Simply changing your Wi-Fi network password will not prevent or stop a KRACK attack, although changing your password from time to time is generally a good idea.

To help prevent attacks, update the operating systems and firmware of all your devices and your router. Another security measure when connecting to public Wi-Fi is to use a VPN (Virtual Private Network) which allows a secure connection to an alternate network. Lastly, if you must use public Wi-Fi and can’t use a VPN, make sure you use at least SSL (secure sockets layer) only by choosing the “always use HTTPS” option in your browser.

And keep in mind that all smart devices are vulnerable to these attacks, not just laptops. the most vulnerable of all They are Android mobile devices.

Companies using Amazon Web Services (AWS) are vulnerable because AWS uses centralized data storage. Any centralized system carries the security risk of having a single point of failure and is therefore vulnerable to attack. AWS provides the majority of cloud security infrastructure for businesses, though research shows 90% of Amazon Simple Storage Service accounts are vulnerable to cyber attacks.

Solutions involving decentralized blockchain-based alternatives eliminate single points of failure in cloud security and can also feature decentralized login credential storage. For example, allowing a user’s login information to remain only on that user’s device, not in a centrally accessible data repository, protects data from cyberattacks more effectively.

Faulty coding issues in networks and communication systems are part of human error and to be expected. However, they can be avoided and, for security reasons, must be avoided. Having a code, especially one that is expected to contain sensitive or personal information, audited by specialized equipment before a system is put into operation and at various intervals thereafter is essential. Make sure systems are well maintained and all software is up to date, as even an incorrectly configured firewall could create a security vulnerability.

Email phishing scams remain a common way for hackers to obtain people’s private information and gain access to vast business networks and their data. In this case, a misleading fake message is used, sometimes pretending to be from a trusted bank, government, or other company, often even using a convincing-looking logo of the agency or company. The email often claims an urgent requirement for sensitive information ironically due to some “security breach”. Through this method, the hacker obtains credentials that they can then use to access personal information or even funds. Also, beware of unauthorized and unknown email attachments that may contain viruses or malware.

ransomware, very common attack method in 2021, it is a kind of extortion through the internet. The victim cannot access data or perform essential functions until a set ransom is paid. In exchange for this ransom, the victim is offered instructions to restore the system or given some kind of decryption key.

Most of the time, ransomware attacks are carried out through malicious parties within an organization, security misconfigurations, or human error. the 2021 Verizon Data Breach Investigations Report found that 85% of these attacks use the “human element”. This suggests more careful attention to human resources, and best practices could be crucial in preventing this type of attack, as well as keeping up with software security measures.

As we face an exciting new chapter of the Internet in the “Metaverse,” we also face other opportunities for cyberattacks on our personal information and corporate data. Individuals, as well as organizations, will need to monitor the data entered into these new systems for entertainment, education, and many other applications. Virtual worlds will require the same, if not more stringent, levels of security and precaution that we already exercise in the physical world and for our online devices.
