I always have considered bloatware a unique attack surface. Instead of the vulnerability being introduced by the operating system, it is introduced by the manufacturer that you bought your machine from. More tech-savvy folk might take the initiative and remove the annoying software that came with their machine, but will an average consumer? Pre-installed bloatware is the most interesting, because it provides a new attack surface impacting a significant number of users who leave the software on their machines.
The market for cheating in video games has grown year after year, incentivizing game developers to implement stronger anti-cheat solutions. A significant amount of game companies have taken a rather questionable route, implementing more and more invasive anti-cheat solutions in a desperate attempt to combat cheaters, still ending up with a game that has a large cheating community. This choice is understandable. A significant amount of cheaters have now moved into the kernel realm, challenging anti-cheat developers to now design mitigations that combat an attacker who shares the same privilege level. However, not all game companies have followed this invasive path, some opting to use anti-cheats that reside in the user-mode realm.
In May, I published a blog post detailing a Remote Code Execution vulnerability in Dell SupportAssist. Since then, my research has continued and I have been finding more and more vulnerabilities. I strongly suggest that you read my previous blog post, not only because it provides a solid conceptual understanding of Dell SupportAssist, but because it’s a very interesting bug.
What computer do you use? Who made it? Have you ever thought about what came with your computer? When we think of Remote Code Execution (RCE) vulnerabilities in mass, we might think of vulnerabilities in the operating system, but another attack vector to consider is “What third-party software came with my PC?”. In this article, I’ll be looking at a Remote Code Execution vulnerability I found in Dell SupportAssist, software meant to “proactively check the health of your system’s hardware and software” and which is “preinstalled on most of all new Dell devices”.
Getting into college is one of the more stressful time of a high school student’s life. Since the admissions process can be quite subjective, students have to consider a variety of factors to convince the admissions officers that “they’re the one”. Some families do as much as they can to improve their chances - even going as far as trying to cheat the system. For wealthier families, this might be donating a very large amount to the school or as we’ve heard in the news recently, bribing school officials.
Enterprises rely on endpoint security software in order to secure machines that have access to the enterprise network. Usually considered the next step in the evolution of anti-virus solutions, endpoint protection software can protect against various attacks such as an employee running a Microsoft Word document with macros and other conventional attacks against enterprises. In this article, I’ll be looking at Carbon Black’s endpoint protection software and the vulnerabilities attackers can take advantage of. Everything I am going to review in this article has been reported to Carbon Black and they have said it is not a real security issue because it requires Administrator privileges.
