PROPHET SPIDER Exploits Citrix ShareFile
At the start of 2022, CrowdStrike Intelligence and CrowdStrike Services investigated an incident in which PROPHET SPIDER exploited CVE-2021-22941 — a remote code execution (RCE) vulnerability impacting Citrix ShareFile Storage Zones Controller — to compromise a Microsoft Internet Information Services (IIS) web server. The adversary exploited the vulnerability to deploy a webshell that enabled the downloading of additional tools. This incident highlights how PROPHET SPIDER continues to evolve their tradecraft while continuing to exploit known web-server vulnerabilities.
The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.

In a first, cryptographic keys protecting SSH connections stolen in new attack | Ars Technica
An error as small as a single flipped memory bit is all it takes to expose a private key. The vulnerability occurs when there are errors during the signature generation that takes place when a client and server are establishing a connection. It affects only keys using the RSA cryptographic algorithm, which the researchers found in roughly a third of the SSH signatures they examined. That translates to roughly 1 billion signatures out of the 3.2 billion signatures examined. Of the roughly 1 billion RSA signatures, about one in a million exposed the private key of the host.
SysAid On-Prem Software CVE-2023-47246 Vulnerability Disclosure
On Nov 2nd, our security team received reports regarding a potential vulnerability in our on-premise software which was being actively exploited. We immediately initiated our incident response protocol and began proactively communicating with our on-premise customers to ensure they could implement a mitigation solution we had identified. We engaged Profero, a cyber security incident response company, to assist us in our investigation. The investigation determined that there was a zero-day vulnerability in the SysAid on-premises software. We urge all customers with SysAid on-prem server installations to ensure that your SysAid systems are updated to version 23.3.36, which remediates the identified vulnerability, and conduct a comprehensive compromise assessment of your network to look for any indicators further discussed below. Should you identify any indicators, take immediate action and follow your incident response protocols.
