Even the solutions designed to keep businesses and organizations safe are vulnerable to the threat of a cyberattack, as when it all boils down, these tools are still software solutions, no matter how secure they might be. The company in question today—Barracuda—is a huge name in the cybersecurity industry, and it has become the victim of a zero-day exploit. Let’s go over how you can prevent your business from experiencing the same thing.
A vulnerability was discovered in Barracuda’s mail Gateway Security application only after it was exploited. This is the part of the email security system that scans email attachments, so it’s an important one. The breach was discovered on May 19th, and patches were swiftly deployed to resolve the vulnerability.
The official statement from the company is as follows:
“Barracuda recently became aware of a security incident impacting our Email Security Gateway appliance (ESG). The incident resulted from a previously unknown vulnerability in our ESG. A security patch to address the vulnerability was applied to all ESG appliances worldwide on Saturday, May 20, 2023. Based on our investigation to date, we've identified unauthorized access affecting a small subset of appliances. As a mitigating measure, all appliances received a second patch on May 21, 2023, addressing the indicators of potential compromise identified to date. We have reached out to the specific customers whose appliances are believed to be impacted at this time. If a customer has not received notice from us via the ESG user interface, we have no reason to believe their environment has been impacted at this time and there are no actions for the customer to take. We thank you for your understanding and support as we work through this issue and sincerely apologize for any inconvenience it may cause.”
Zero-day exploits are those that were previously unknown to security researchers, only having been discovered after they are actively being targeted by a threat. The severity of these exploits can vary, but they are extremely difficult to detect, as they often go undiscovered and undetected for quite a long time. After all, you can’t protect against something that you don’t know exists. Eventually, these vulnerabilities can become serious problems and logistical nightmares for security companies and businesses alike.
The worst part of dealing with a zero-day vulnerability is not knowing if one exists, as well as not knowing how long they have existed for. In the case of this exploit, it doesn’t appear to be too long, but any vulnerability in Barracuda’s ESG system is going to cause quite a stir. Businesses use a lot of software throughout the course of their operations, and the same issue could happen for any application on your network. You need to have a strategy in place to handle potential threats as they arise or become known, and it starts with making sure that patches are tested and deployed as soon as they are available.
Preferred can help your business deploy patches and updates in a quick and efficient manner using our remote patch deployment solutions. We can keep your software secure and safe from all threats, and if zero-day exploits do arise, we’ll do what we can to deploy fixes and assess damages. To learn more, call us at 708-781-7110 today.
