How Many Engineers Does It Take to Digitally Secure a Solar Panel?
www.nist.gov/blogs/cybersecurity-insights/how-many-engineers-does-it-take-digitally-secure-solar-panel The headline for this blog post is not a trick question or the beginning of a bad joke. I asked this question maybe a bit facetiously when I met the National Cybersecurity Center of Excellence (NCCoE) energy sector team in late 2018. The NCCoE had just purchased a solar panel to install in the lab. I genuinely wanted to know: what vulnerabilities exist when solar panels connect to the distribution grid, and how can we mitigate them?

Airplane Hack Exposes Weaknesses of Alert and Avoidance Systems
threatpost.com/airplane-hack-exposes-weaknesses-of-alert-and-avoidance-systems/155451/ The aircraft safety system known as the Traffic Alert and Collision Avoidance System (TCAS) can be coerced into sending an airplane on a mid-air rollercoaster ride much to the horror of those onboard. Researchers were able to cobble together an effective method for spoofing the TCAS using a $10 USB-based Digital Video Broadcasting dongle and a rogue transponder, for communicating with aircraft. “We have shown that careful placing of fake aircraft through rogue transponder broadcasts can cause an aircraft under autopilot control to climb or descend towards legitimate traffic, ” wrote Pen Test Partners’ Ken Munro in a blog post outlining his research. also:

Mitigating vulnerabilities in endpoint network stacks
www.microsoft.com/security/blog/2020/05/04/mitigating-vulnerabilities-endpoint-network-stacks/ One aspect of our proactive security work is finding vulnerabilities and fixing them before they can be exploited. Innovations we’ve made in our fuzzing technology have made it possible to get deeper coverage than ever before, resulting in the discovery of new bugs, faster. One such vulnerability is the remote code vulnerability (RCE) in Microsoft Server Message Block version 3 (SMBv3) tracked as CVE-2020-0796 and fixed on March 12, 2020. In the following sections, we will share the tools and techniques we used to fuzz SMB, the root cause of the RCE vulnerability, and relevant mitigations to exploitation.
