Kr00k Wi-Fi Vulnerability Leads to Widespread Concerns
There is a vulnerability at the layer 2 Wi-Fi encryption level called Kr00k (formally CVE-2019-15126 in the NIST National Vulnerability Database) affecting Broadcom and Cypress Semiconductor Wi-Fi devices.
Broadcom and Cypress Wi-Fi technology are two of the most popular wireless chip technologies in the market, prevalent in mobile phones, laptops, wireless access points, and internet of things (IoT) devices. Both PC and MacOS devices are reported as subject to this bug.
Researchers from antivirus vendor ESET, who discovered the vulnerability, presented their findings at the RSA Conference 2020.
“Kr00k manifests itself after Wi-Fi disassociations – which can happen naturally, for example due to a weak Wi-Fi signal, or may be manually triggered by an attacker,” said lead ESET researcher Miloš Cermák. “If an attack is successful, several kilobytes of potentially sensitive information can be exposed. By repeatedly triggering disassociations, the attacker can capture a number of network packets with potentially sensitive data.”
Exploit of the vulnerability can occur when Wi-Fi devices disassociate with their WLAN access points, a common occurrence in weak signal scenarios and is usually corrected automatically by the Wi-Fi hardware and WLAN protocols.
Data leak is always of concern to corporate IT departments.Many manufacturers have released patches that should be applied on all devices at the infrastructure and endpoint levels. Consult with your hardware vendors to determine if a patch for your various platforms is available and schedule their installation as soon as possible.
Qualys VMDR and Ivanti have announced a new partnership dedicated to improving the detection and patching of vulnerabilities. Announced July 30, the Qualys and Ivanti Partnership have already gone live as an integrated component of the VMDR solution.
RiskSense announced on July 13 its new version of the cloud-delivered RiskSense risk management platform. The main draw of the program is its holistic risk calculation across CVEs and CWEs.
Cyberthreats are omnipresent for any enterprise. Monitoring ingress and egress points while still conducting business is a balance security professionals attempt to strike. Couple this with the continued security issues around remote work during the pandemic, and security teams have their hands full.
On May 26, Kenna Security released its new Prioritization to Prediction Benchmark Survey. This free tool provides organizations with the ability to compare their vulnerability management programs to industry averages Kenna Security has compiled over the years.
COVID-19 has changed a great deal about how businesses operate. From a security perspective, however, COVID-19 caught many businesses off guard. The shift from working in the office to working from home has made it difficult for security measures to keep pace. Specifically, how are businesses meant to maintain the same secure networks when their employees are no longer working in the office? Outside of the security of the IT departments, IT and security have a tough time ensuring that patching and vulnerability management remain at the forefront of a business’s priorities.
Google has identified “unsafe” code in the Chromium web browser engine. This flaw introduces a potential vulnerability that effects Google Chrome, as well as all Chromium-based web browsers.
More than ever, cybersecurity solutions are core to any MSPs offering. No longer should technology service providers be farming this out to dedicated security providers. Trust and peace of mind are the core tenets of what they are selling and solutions like Acronis Cyber Protect Cloud can provide the platform upon which to deliver on those promises.
Kenna Security deployed their new data driven vulnerability management program, Kenna.VM and accessory program, Kenna.VI. Released on April 28th, Kenna.VM was created with the purpose to set service-level agreements (SLAs) with risk tolerance in mind.
We often hear that businesses are continually cyber insecure or under attack. However, recent penetration testing from Rapid7 shows that businesses are getting better at securing their networks against cyberattacks. While organizations continue to have exploitable weaknesses, attackers are having greater difficulty penetrating deeper into businesses’ networks.
