The NCF outlines how it conducts responsible cyber operations to counter state threats, support military operations, and disrupt terrorists and serious crime

SentinelLabs uncover a previously unknown set of espionage campaigns conducted by Winter Vivern advanced persistent threat (APT) group.

A DLL named guard64.dll, which was loaded into the infected 3CXDesktopApp.exe process, was used in recent deployments of a backdoor that we dubbed “Gopuram” and had been tracking internally since 2020.

* Check Point Research (CPR) and Check Point Incident Response Team (CPIRT) encountered a previously unnamed ransomware strain, we dubbed Rorschach, deployed against a US-based company. Rorschach ransomware appears to be unique, sharing no overlaps that could easily attribute it to any known ransomware strain. In addition, it does not bear any kind of branding which is a common practice among ransomware groups. * The ransomware is partly autonomous, carrying out tasks that are usually manually performed during enterprise-wide ransomware deployment, such as creating a domain group policy (GPO). In the past, similar functionality was linked to LockBit 2.0. * The ransomware is highly customizable and contains technically unique features, such as the use of direct syscalls, rarely observed in ransomware. Moreover, due to different implementation methods, Rorschach is one of the fastest ransomware observed, by the speed of encryption. * The ransomware was deployed using DLL side-loading of a Cortex XDR Dump Service Tool, a signed commercial security product, a loading method which is not commonly used to load ransomware. The vulnerability was properly reported to Palo Alto Networks.

FortiGuard Labs highlights how a digitally signed 3CX desktop app was reportedly used in a supply chain attack against 3CX Voice over Internet Protocol (VoIP) customers. Check back for analysis and coverage updates.

A new ransomware gang named 'Money Message' has appeared, targeting victims worldwide and demanding million-dollar ransoms not to leak data and release a decryptor.

While many apps collect vast troves of user data, sometimes without explicit consent, experts say Chinese e-commerce giant Pinduoduo has taken violations of privacy and data security to the next level.

QiAnXin Threat Intelligence Center's RedDrip team tracked the relevant events and discovered a batch of attack samples exploiting the CVE-2023-23397 vulnerability. After analyzing these samples and C2 servers, we believe that the exploitation of this vulnerability in the wild has been ongoing since March 2022. In the later stages of the attack, the attackers used Ubiquiti-EdgeRouter routers as C2 servers, and the victims of the attack activity were from multiple countries.
