A vulnerability was recently discovered that is effectively guaranteed to impact all computer users, from private users to businesses. While this situation will take some time to resolve fully, we want to make sure you know everything that needs to be done to protect yourself from Log4j.

The recent discovery of four flaws in Microsoft’s Exchange Server software came too late to prevent a rash of stolen emails, but that doesn’t mean you need to remain vulnerable to this attack. Let’s go over the story so far, and how you can help protect your business.

True to form, 2020 has given us a final parting gift: the news that the United States was targeted this year by the biggest cyberespionage attack ever. Let’s go into the ramifications of this attack, and what it should teach us going forward.

Hackers and cybercriminals, like most people, tend to gravitate towards high-reward activities. In this case, that means that focus is turning to creating malware that attacks the router, potentially infecting the users that leverage it to connect wirelessly to the Internet. Researchers at Kaspersky Lab recently discovered an example of such a malware, so today, we will review this threat and how to best protect your network.

Virtual private networks are vulnerable to an exploit that was recently brought to light. Cisco has announced that this exploit undermines its ASA, or Adaptive Security Appliance tool. If this issue isn’t patched immediately, you could find your organization vulnerable through remote code exploitation.

A major vulnerability has been discovered that affects everyone that uses Wi-Fi. Key Reinstallation Attack, or KRACK, affects the core encryption protocol that most Wi-Fi users depend upon to shield their browsing from others, Wi-Fi Protected Access 2 (WPA2).

Using the most up-to-date versions of your technology’s operating systems is one of the best ways to stay secure. Yet, some organizations forego the jump to more recent operating systems due to the immense up-front expense represented by upgrading multiple servers or workstations at once. Unfortunately, this can be detrimental to your organization’s security, and potentially even put your business’s future at risk.

A new malware swept across the globe Tuesday, incorporating facets of many ransomwares that have made headlines recently. While it originally appeared to be a variant of the Petya ransomware, it has been determined that it shares more in common with WannaCry. However, “NotPetya,” as it has been named, has a few additional features that experts say make it worse than either of its predecessors.

Every security professional’s worst nightmare consists of the National Security Agency (NSA) being hacked. While there’s no proof that the NSA itself has been hacked, there is some evidence to suggest that some of the exploits used by the agency are up for grabs on the black market. What this means is that a lucky group of hackers could potentially get their hands on some very dangerous tools.

27 vulnerabilities: The amount of vulnerabilities that were resolved with the round of security patches in Microsoft’s latest Patch Tuesday. Windows, Microsoft Office, Internet Explorer, the Edge browser, and more, were all affected. It’s important to patch these vulnerabilities as soon as possible, especially if you haven’t done so already.

The Petya ransomware, a particularly vicious monster of a threat, has returned and is not alone. Petya now comes bundled together with Mischa, yet another ransomware that works well alongside Petya. The ransomware is delivered via an inconspicuous email disguised as a job application with a resume attached. Once the user downloads the file, Petya encrypts the files located on the device.

While security experts tend to focus the brunt of their discussions on desktop OS vulnerabilities, there are plenty of mobile malware threats that fly under the radar. One such malware is called Hummer; a trojan that installs unwanted apps and malware on a device, and can be found on over a million phones worldwide.

No security solution is perfect. Each one has its own set of pros and cons. For example, relying completely on an automated solution is thorough, but it will flag plenty of threats that aren’t really threats (aka, false positives). Meanwhile, a human overseeing security is great for spotting worrisome trends, but a human can’t possibly catch every single attack. With this dynamic in mind, a team of researchers from MIT has successfully blended the two.

One of the latest vulnerabilities in open-source software can be found in 7zip, a file archiver and decompresser. 7zip has been found to have several security vulnerabilities which have software developers rushing to fix their products. The damage done extends far beyond 7zip, reaching both people who use 7zip itself, and developers who have used the technology in the creation of their own tools and software.

One minute you’re browsing trusted sites on the Internet, the next, your PC freezes up and displays the dreaded blue screen of death, along with a fake tech support message. This strain of malware is duping plenty of computer users into calling the provided phone number, which only makes the situation worse.

For many Windows users, the fact that Microsoft is issuing Windows 10 incrementally came as a shock for those who patiently waited for its release date. While users wait, however, hackers are taking advantage of those who are less patient by creating a ransomware that disguises itself as a launcher for a Windows 10 download. So, while you sit and wait for your version of the latest OS, don’t fall prey to deals that seem too good to be true.

Microsoft’s latest PC operating system arrived with fanfare, and has received overwhelmingly positive reviews so far, but is it ready for your business? Let’s take it for a spin and find out.

As seen by the recent Superfish app debacle, software that comes preinstalled on a new PC shouldn’t always be trusted. Most of the time, the innate software on a device can be trusted; but the Superfish application is an exception. This app, which came preinstalled on new Lenovo PCs between the months of September and December of 2014, can potentially compromise the security of your machine.

As a business owner, you have an obligation to keep your data and network files safe from prying eyes and criminals. The latest threats, like the new Cryptowall 2.0 ransomware, can be a difficult hurdle to jump, especially when they are disguised and designed to ruin you. Thankfully, you don’t have to take on these threats alone.
