Thousands of small to medium size businesses are suffering as Rackspace have suffered a security incident on their Hosted Exchange service.
Yesterday, 2nd December 2022, Rackspace announced an outage to their Hosted Exchange Server:
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.
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.
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.
Years-old domains, compromised JS libraries and worldwide-localized content among tactics of this sophisticated attacker.
La cour d'appel de Paris a confirmé cette semaine (lundi), la mise en examen de la société française Amesys pour complicité d'actes de torture dans l'enquête sur la vente d’un programme de cybersurveillance au régime libyen de Mouammar Kadhafi. Deux des chefs de l'entreprise ont été inculpés, ce qui rend la société complice d'exactions en Libye.
Cyber threat intelligence largely involves the tracking and studying of the adversaries outside of your network. Gaining counterintelligence about your adversaries' capabilities and weaponry is one of the final building blocks for managing a strong cyber defense. In the pursuit of performing this duty, I have been studying how to discover adversary infrastructure on the internet. One good way of doing this has been via leveraging the scan data available through the popular Shodan search engine. If you've not used it before, Shodan periodically scans the entire internet and makes it available for users to query through. It is often used to monitor networks, look for vulnerabilities, and ensure the security of an organization's perimeter.
Someone is allegedly selling up-to-date mobile phone numbers of nearly 500 million WhatsApp users. A data sample investigated by Cybernews likely confirms this to be true.
