In July 2024, Volexity identified exploitation of a zero-day credential disclosure vulnerability in Fortinet’s Windows VPN client that allowed credentials to be stolen from the memory of the client’s process. This vulnerability was discovered while analyzing a recent sample of the DEEPDATA malware family. DEEPDATA is a modular post-exploitation tool for the Windows operating system that is used to gather a wide range of information from target devices. Analysis of the sample revealed a pl...| Volexity
In 2024, Volexity identified a cyber-espionage campaign undertaken by a suspected Pakistan-based threat actor that Volexity currently tracks under the alias UTA0137. The malware used in these recent campaigns, which Volexity tracks as DISGOMOJI, is written in Golang and compiled for Linux systems. Volexity assesses with high confidence that UTA0137 has espionage-related objectives and a remit to target government entities in India. Based on Volexity’s analysis, UTA0137’s campaigns appear ...| Volexity
Last month, Volexity reported on its discovery of zero-day, in-the-wild exploitation of CVE-2024-3400 in the GlobalProtect feature of Palo Alto Networks PAN-OS by a threat actor Volexity tracks as UTA0218. Volexity has conducted several additional incident response investigations and proactive analyses of Palo Alto Networks firewall devices since the initial two cases described in Volexity’s blog post. Volexity believes with moderate confidence that UTA0218 is a China-based threat actor bas...| Volexity
Through its managed security services offerings, Volexity routinely identifies spear-phishing campaigns targeting its customers. One persistent threat actor, whose campaigns Volexity frequently observes, is the Iranian-origin threat actor CharmingCypress (aka Charming Kitten, APT42, TA453). Volexity assesses that CharmingCypress is tasked with collecting political intelligence against foreign targets, particularly focusing on think tanks, NGOs, and journalists.| Volexity
Volexity regularly prioritizes memory forensics when responding to incidents. This strategy improves investigative capabilities in many ways across Windows, Linux, and macOS. This blog post highlights some specific ways memory forensics played a key role in determining how two zero-day vulnerabilities were being chained together to achieve unauthenticated remote code execution in Ivanti Connect Secure VPN devices.| Volexity
In early February 2022, notably just ahead of the Russian invasion of Ukraine, Volexity made a discovery that led to one of the most fascinating and complex incident investigations Volexity had ever worked. The investigation began when an alert from a custom detection signature Volexity had deployed at a customer site (“Organization A”) indicated a threat actor had compromised a server on the customer’s network. While Volexity quickly investigated the threat activity, more questions wer...| Volexity
In mid-2023, Volexity detected and responded to multiple incidents involving systems becoming infected with malware linked to StormBamboo (aka Evasive Panda, and previously tracked by Volexity under “StormCloud”). In those incidents, multiple malware families were found being deployed to macOS and Windows systems across the victim organizations’ networks.| Volexity
On April 10, 2024, Volexity identified zero-day exploitation of a vulnerability found within the GlobalProtect feature of Palo Alto Networks PAN-OS at one of its network security monitoring (NSM) customers. Volexity received alerts regarding suspect network traffic emanating from the customer’s firewall. A subsequent investigation determined the device had been compromised. The following day, April 11, 2024, Volexity observed further, identical exploitation at another one of its NSM custome...| Volexity
On January 15, 2024, Volexity detailed widespread exploitation of Ivanti Connect Secure VPN vulnerabilities CVE-2024-21887 and CVE-2023-46805. In that blog post, Volexity detailed broader scanning and exploitation by threat actors using still non-public exploits to compromise numerous devices. Subsequently, Volexity has observed an increase in attacks from various threat actors against Ivanti Connect Secure VPN appliances beginning the same day.| Volexity
On January 10, 2024, Volexity publicly shared details of targeted attacks by UTA0178 exploiting two zero-day vulnerabilities (CVE-2024-21887 and CVE-2023-46805) in Ivanti Connect Secure (ICS) VPN appliances. On the same day, Ivanti published a mitigation that could be applied to ICS VPN appliances to prevent exploitation of these vulnerabilities. Since publication of these details, Volexity has continued to monitor its existing customers for exploitation. Volexity has also been contacted by m...| Volexity
