Certpotato – using adcs to privesc from virtual and network service accounts to local system
Certpotato – using adcs to privesc from virtual and network service accounts to local system
The goal of this blog post is to present a privilege escalation I found while working on ADCS. We will see how it is possible to elevate our privileges to NT AUTHORITY\SYSTEM from virtual and network service accounts of a domain-joined machine (for example from a webshell on a Windows server) using ADCS. I want to call this attack chain “CertPotato” as homage to other *Potato tools and as a way to better remember it. A popular technique for getting SYSTEM from a virtual or network service account is Delegate 2 Thyself by Charlie Clark. This technique involves using RBCD to elevate your privileges. In this article, I propose an alternative approach to become local SYSTEM using ADCS.

Preparing for a Russian cyber offensive against Ukraine this winter
Preparing for a Russian cyber offensive against Ukraine this winter
As we report more fully below, in the wake of Russian battlefield losses to Ukraine this fall, Moscow has intensified its multi-pronged hybrid technology approach to pressure the sources of Kyiv’s military and political support, domestic and foreign. This approach has included destructive missile and cyber strikes on civilian infrastructure in Ukraine, cyberattacks on Ukrainian and now foreign-based supply chains, and cyber-enabled influence operations[1]—intended to undermine US, EU, and NATO political support for Ukraine, and to shake the confidence and determination of Ukrainian citizens.

Google Online Security Blog: Memory Safe Languages in Android 13
As the amount of new memory-unsafe code entering Android has decreased, so too has the number of memory safety vulnerabilities. From 2019 to 2022 it has dropped from 76% down to 35% of Android’s total vulnerabilities. 2022 is the first year where memory safety vulnerabilities do not represent a majority of Android’s vulnerabilities.
