Experts Warn of Widespread SonicWall VPN Compromise Impacting Over 100 Accounts

Experts Warn of Widespread SonicWall VPN Compromise Impacting Over 100 Accounts

Oct 11, 2025 Cloud Security / Network Security
Cybersecurity company Huntress on Friday warned of "widespread compromise" of SonicWall SSL VPN devices to access multiple customer environments. "Threat actors are authenticating into multiple accounts rapidly across compromised devices," it said . "The speed and scale of these attacks imply that the attackers appear to control valid credentials rather than brute-forcing." A significant chunk of the activity is said to have commenced on October 4, 2025, with more than 100 SonicWall SSL VPN accounts across 16 customer accounts having been impacted. In the cases investigated by Huntress, authentications on the SonicWall devices originated from the IP address 202.155.8[.]73. The company noted that in some instances, the threat actors did not engage in further adversarial actions in the network and disconnected after a short period of time. However, in other cases, the attackers have been found conducting network scanning activity and attempting to access...

Hackers Turn Velociraptor DFIR Tool Into Weapon in LockBit Ransomware Attacks

Oct 11, 2025 Network Security / Vulnerability
Threat actors are abusing Velociraptor, an open-source digital forensics and incident response (DFIR) tool, in connection with ransomware attacks likely orchestrated by Storm-2603 (aka CL-CRI-1040 or Gold Salem), which is known for deploying the Warlock and LockBit ransomware. The threat actor's use of the security utility was documented by Sophos last month. It's assessed that the attackers weaponized the on-premises SharePoint vulnerabilities known as ToolShell to obtain initial access and deliver an outdated version of Velociraptor (version 0.73.4.0) that's susceptible to a privilege escalation vulnerability ( CVE-2025-6264 ) to enable arbitrary command execution and endpoint takeover, per Cisco Talos . In the attack in mid-August 2025, the threat actors are said to have made attempts to escalate privileges by creating domain admin accounts and moving laterally within the compromised environment, as well as leveraging the access to run tools like Smbexec to remotely...

China-Linked PlugX and Bookworm Malware Attacks Target Asian Telecom and ASEAN Networks

Sep 27, 2025 Malware / Network Security
Telecommunications and manufacturing sectors in Central and South Asian countries have emerged as the target of an ongoing campaign distributing a new variant of a known malware called PlugX (aka Korplug or SOGU). "The new variant's features overlap with both the RainyDay and Turian backdoors, including abuse of the same legitimate applications for DLL side-loading, the XOR-RC4-RtlDecompressBuffer algorithm used to encrypt/decrypt payloads and the RC4 keys used," Cisco Talos researchers Joey Chen and Takahiro Takeda said in an analysis published this week. The cybersecurity company noted that the configuration associated with the PlugX variant diverges significantly from the usual PlugX configuration format, instead adopting the same structure used in RainyDay , a backdoor associated with a China-linked threat actor known as Lotus Panda (aka Naikon APT). It's also likely tracked by Kaspersky as FoundCore and attributed to a Chinese-speaking threat group it calls...
