Popular video conferencing app Zoom has addressed several security vulnerabilities, two of which affect its Linux client that could have allowed an attacker with access to a compromised system to read and exfiltrate Zoom user data—and even run stealthy malware as a sub-process of a trusted application. According to cybersecurity researcher Mazin Ahmed , who presented his findings at DEF CON 2020 yesterday, the company also left a misconfigured development instance exposed that wasn't updated since September 2019, indicating the server could be susceptible to flaws that were left unpatched. After Ahmed privately reported the issues to Zoom in April and subsequently in July, the company issued a fix on August 3 (version 5.2.4). It's worth noting that for some of these attacks to happen, an attacker would need to have already compromised the victim's device by other means. But that doesn't take away the significance of the flaws. In one scenario, Ahmed uncov...

Popular video conferencing app Zoom recently fixed a new security flaw that could have allowed potential attackers to crack the numeric passcode used to secure private meetings on the platform and snoop on participants. Zoom meetings are by default protected by a six-digit numeric password, but according to Tom Anthony, VP Product at SearchPilot who identified the issue , the lack of rate limiting enabled "an attacker to attempt all 1 million passwords in a matter of minutes and gain access to other people's private (password protected) Zoom meetings." It's worth noting that Zoom began requiring a passcode for all meetings back in April as a preventive measure to combat Zoom-bombing attacks, which refers to the act of disrupting and hijacking Zoom meetings uninvited to share obscene and racist content. Anthony reported the security issue to the company on April 1, 2020, along with a Python-based proof-of-concept script, a week after which Zoom patched the flaw...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
