The transition to the cloud has changed everything! It has upended where apps are hosted, as well as the movement of enterprises’ most valuable digital assets and sensitive data. Access has been redefined and firewall-based perimeters are a thing of the past. Now special considerations are required for users working from everywhere—on both managed and unmanaged devices—as well as address the ever-growing Internet of Things (IoT).
Recently, researchers from Positive Security published findings identifying a major remote code execution (RCE) vulnerability in dompdf, a popular PDF generation library. In their reporting, they outlined a way that code could be loaded into an application and then remotely executed during a PDF being generated. Dompdf is used quite extensively within the PHP ecosystem, and is used within over 59,000 open sourced platforms and projects.
In today's ecosystems, a single enterprise can operate multiple internal networks, remote offices with their own local infrastructure, remote and/or mobile individuals and Cloud services. According to the study published by NIST, this level of complexity is too much for legacy network security models that are based on the location of the company infrastructure and there isn’t a single, easily identifiable perimeter for all elements.
Recently, we encountered an interesting phishing webpage that caught our interest because it acts like a chameleon by changing and blending its color based on its environment. In addition, the site adapts its background page and logo depending on user input to trick its victims into giving away their email credentials. We see an email with the “initial” URLs in the example below: Figure 1. The raw phishing email showing the URLs, purporting to be a fax message that needs to be accessed.
Threat actors continue to exploit users, devices and applications, especially as more of them exist outside of the traditional corporate perimeter. With employees consistently working remotely, adversaries are taking advantage of distributed workforces and the poor visibility and control that legacy security tools provide.
Data bias: the insidious threat lurking in your data unless you’ve taken active steps to mitigate it. It causes the potential to harm, skew or invalidate your data completely – or sometimes all three at once.
Security operation teams continuously aim to focus on two main things: 1. Real cyber security threats (also known as “True Positive Alerts”), and 2. Reducing response time, especially when you have so many different sources to monitor. However, in reality, we deal with hundreds of security alerts on a daily basis, many of which are false positives that waste our valuable time. This is where incident response/security automation becomes a requirement rather than nice to have.
