Hackers KRACK WiFi security

November 2, 2017 admin Security 2017november2security_c, ethernet, https, krack, patch, public wifi, vpn, wifi, wpa2

For ages, most people assumed that setting a strong password on their WiFi router was enough to prevent cyberattacks, but recent events prove otherwise. Two Belgian security analysts have found a serious weakness in WiFi networks, called KRACK, that puts your wireless devices in danger.

What is KRACK?
Simply put, KRACK, short for ‘key reinstallation attack,’ allows hackers to bypass WPA2 — a security protocol used by routers and devices to encrypt activity — and intercepts sensitive data passing between the mobile device and the wireless router, including login details, credit card numbers, private emails, and photos.

In extreme cases, KRACKed devices can be remotely controlled. For example, hackers can log in to your surveillance systems and shut them down.

What’s worse, Internet of Things devices — like smart thermostats and IP cameras — rarely receive security fixes, and even if some are available, applying patches are difficult, as these devices tend to have complex user interfaces.

The good news, however, is you can do several things to mitigate the risks.

Download patches immediately
According to recent reports, security patches have already been released for major platforms, including iOS, Windows, and Android. Router manufacturers such as Ubiquiti, Mikrotik, Meraki, and FortiNet have also issued firmware updates, so make sure to install them as soon as possible.

Although IoT patches are rare, consider getting your smart devices from reputable vendors that push out updates regularly. It’s also a good idea to contact a managed services provider to install the updates for you.

Use Ethernet connections
Some wireless routers don’t yet have a security patch, so while you’re waiting, use an Ethernet cable and disable your router’s wireless setting. Turn off the WiFi on your devices as well to make sure you’re not connecting to networks susceptible to KRACK.

Stay off public networks
Free public WiFi networks — even ones that are password-protected — in your local cafe should also be avoided because they usually don’t have holistic security measures in place, making them easy targets for cybercriminals.

Connect to HTTPS websites
If you do need to connect to a public WiFi hotspot, visit websites that start with “HTTPS,” and stay away from ones that are prefaced with “HTTP.” This is because HTTPS websites encrypt all traffic between your browser and the website, regardless of whether the connection is vulnerable to KRACK

Hop on a Virtual Private Network (VPN)
You can also use a VPN service to hide all network activity. Simply put, VPNs encrypt your internet connection so that all the data you’re transmitting is safe from prying eyes.

Although the potential impact of a KRACK hack is devastating, security awareness and top-notch support are the best ways to stay safe online. Want more security tips? Contact us today.

9 cybersecurity terms everyone must know

2016September21_Security_C_PH.jpg

2016september21_security_cEveryone, from doctors to lawyers, needs to continue learning to stay ahead of the times. Business owners might have it worst of all, oftentimes needing to stay on top of several industries to keep their company running. Keep reading for a refresher on all the latest trends and buzzwords used in the cybersecurity sector.

Malware

For a long time, the phrase ‘computer virus’ was misappropriated as a term to define every type of attack that intended to harm or hurt your computers and networks. A virus is actually a specific type of attack, or malware. Whereas a virus is designed to replicate itself, any software created for the purpose of destroying or unfairly accessing networks and data should be referred to as a type of malware.

Ransomware

Don’t let all the other words ending in ‘ware’ confuse you; they are all just subcategories of malware. Currently, one of the most popular of these is ‘ransomware,’ which encrypts valuable data until a ransom is paid for its return.

Intrusion Protection System

There are several ways to safeguard your network from malware, but intrusion protection systems (IPSs) are quickly becoming one of the non-negotiables. IPSs sit inside of your company’s firewall and look for suspicious and malicious activity that can be halted before it can deploy an exploit or take advantage of a known vulnerability.

Social Engineering

Not all types of malware rely solely on fancy computer programming. While the exact statistics are quite difficult to pin down, experts agree that the majority of attacks require some form of what is called ‘social engineering’ to be successful. Social engineering is the act of tricking people, rather than computers, into revealing sensitive or guarded information. Complicated software is totally unnecessary if you can just convince potential victims that you’re a security professional who needs their password to secure their account.

Phishing

Despite often relying on face-to-face interactions, social engineering does occasionally employ more technical methods. Phishing is the act of creating an application or website that impersonates a trustworthy, and often well-known business in an attempt to elicit confidential information. Just because you received an email that says it’s from the IRS doesn’t mean it should be taken at face value — always verify the source of any service requesting your sensitive data.

Anti-virus

Anti-virus software is often misunderstood as a way to comprehensively secure your computers and workstations. These applications are just one piece of the cybersecurity puzzle and can only scan the drives on which they are installed for signs of well known malware variants.

Zero-day attacks

Malware is most dangerous when it has been released but not yet discovered by cybersecurity experts. When a vulnerability is found within a piece of software, vendors will release an update to amend the gap in security. However, if cyber attackers release a piece of malware that has never been seen before, and if that malware exploits one of these holes before the vulnerability is addressed, it is called a zero-day attack.

Patch

When software developers discover a security vulnerability in their programming, they usually release a small file to update and ‘patch’ this gap. Patches are essential to keeping your network secure from the vultures lurking on the internet. By checking for and installing patches as often as possible, you keep your software protected from the latest advances in malware.

Redundant data

When anti-virus software, patches, and intrusion detection fail to keep your information secure, there’s only one thing that will: quarantined off-site storage. Duplicating your data offline and storing it somewhere other than your business’s workspace ensures that if there is a malware infection, you’re equipped with backups.

We aren’t just creating a glossary of cyber security terms; every day, we’re writing a new chapter to the history of this ever-evolving industry. And no matter what you might think, we are available to impart that knowledge on anyone who comes knocking. Get in touch with us today and find out for yourself.
