Month: April 2024
Welcome to the Sensor Intel Series installment for January 2023. The purpose of this recurring monthly brief is to provide security practitioners with vulnerability targeting intelligence so that they can make better-informed decisions about patching and vulnerability remediation. The source of this intelligence is log data from a globally distributed network of passive sensors. While…
Read MoreClosing the Cybersecurity Skills Gap, Part 3 In part one of our discussion on the cybersecurity skills gap, we discussed how organizations can develop their own cybersecurity professionals as opposed to trying to hire them. In part two, we explored where to begin in cybersecurity and the basic skills needed any cybersecurity professional needs. Now…
Read MoreMitigating FluBot David Warburton, principal threat research evangelist with F5 Labs, offers the following suggestions for mitigating FluBot. Prevent FluBot relies on tricking the user into downloading a trojan hosted on an attacker-controlled server. Android phones will, by default, prevent installation from outside of the Google Play store, though attackers know this and coach the…

Read MoreAlso notable this month is the dramatic growth in CVE-2020-25078, which is also an IoT vulnerability but this time in several IP cameras. On the one hand the volume of traffic scanning for this vulnerability was not remarkable, with ~3600 connections in February, but only 200 connections were attempted in January, which means traffic increased…

Read MoreBoth the car repair and travel app scenarios begin with the concept of request and response. Someone or something requests a service, and fulfillment only occurs in response to a request. The facilitator of the request is the interface; it is not just a messenger but also an interpreter. Few of us speak “the language…
Read MoreHere we are in April 2023, which gives us another opportunity to see what vulnerabilities attackers were most interested in last month. After receiving a huge amount of attacker attention from November 2022 to February 2023, CVE-2020-8958 has returned to volumes of traffic more consistent with what we’d come to expect over the last year…
Read MoreWhy does vulnerability management fail? There are a couple of reasons: Enterprise IT teams can’t keep up with all the vulnerabilities because secure coding hasn’t been, and still isn’t, a priority across all organizations that write software. In a recent F5 security event where 300 participants responded to live polling, 21% of respondents said they…
