You may have noticed that cyberattacks on critical infrastructure have been on the uptick in recent months. Targets have ranged from a water treatment facility in Florida, which ultimately failed, to the Colonial Pipeline, which succeeded in...
We talk about buffer overflows a lot. So much so, it almost seems silly to be writing another article dedicated to this software vulnerability. But, it’s worth driving the point home: buffer overflows are one of the most dangerous software...
In March 2021, Arm announced the release of its new Armv9 architecture. The first new architecture in a decade, Armv9 includes new security features—from compartmentalization to memory safety to pointer authentication.
The ever-expanding universe of cybersecurity threats plaguing embedded systems today is only getting more dangerous, costly, and pervasive with every year that passes.
The threat universe for embedded systems is seemingly endless. To try to make sense of it all, we turn to MITRE’s CWE database. It’s a publicly-available, community-developed list of software and hardware weaknesses. Its purpose is to serve as...
In order to make sense of the many threats plaguing embedded systems today, we turn to MITRE’s Common Weakness Enumeration (CWE) database. This database serves as a tool to help categorize the tens of thousands of common vulnerabilities and...
In order to understand the many potential cyberattacks that threaten you and your organization, we turn to MITRE’s Common Weakness Enumeration (CWE) database as a key first step.
Compartmentalization is one of the seven layers in the Cybersecurity Stack. It works by separating data and software on a processor into different compartments to effectively limit the scope of damage of potential cyberattacks only to the...
In January 2021, a major buffer overflow vulnerability, impacting a large chunk of the Linux ecosystem, was discovered in the sudo application by security auditing firm, Qualys. The vulnerability, known widely as “Baron Samedit,” received a CVE...
It wasn’t too long ago that we wrote a roundup of the severe buffer overflow vulnerabilities discovered in the just the first quarter of 2021, but the all-too-common bug has made the news yet again.
