Cybersecurity researchers are calling attention to a new campaign that delivers the Astaroth banking trojan that employs GitHub as a backbone for its operations to stay resilient in the face of infrastructure takedowns. "Instead of relying solely on traditional command-and-control (C2) servers that can be taken down, these attackers are leveraging GitHub repositories to host malware configurations," McAfee Labs researchers Harshil Patel and Prabudh Chakravorty said in a report. "When law enforcement or security researchers shut down their C2 infrastructure, Astaroth simply pulls fresh configurations from GitHub and keeps running." The activity, per the cybersecurity company, is primarily focused on Brazil, although the banking malware is known to target various countries in Latin America, including Mexico, Uruguay, Argentina, Paraguay, Chile, Bolivia, Peru, Ecuador, Colombia, Venezuela, and Panama. This is not the first time Astaroth campaigns have trained t...

Cybersecurity researchers have disclosed details of a new Rust-based backdoor called ChaosBot that can allow operators to conduct reconnaissance and execute arbitrary commands on compromised hosts. "Threat actors leveraged compromised credentials that mapped to both Cisco VPN and an over-privileged Active Directory account named, 'serviceaccount,'" eSentire said in a technical report published last week. "Using the compromised account, they leveraged WMI to execute remote commands across systems in the network, facilitating the deployment and execution of ChaosBot." The Canadian cybersecurity company said it first detected the malware in late September 2025 within a financial services customer's environment. ChaosBot is noteworthy for its abuse of Discord for command-and-control (C2). It gets its name from a Discord profile maintained by the threat actor behind it, who goes by the online moniker "chaos_00019" and is responsible for issuin...

Oracle on Saturday issued a security alert warning of a fresh security flaw impacting its E-Business Suite that it said could allow unauthorized access to sensitive data. The vulnerability, tracked as CVE-2025-61884 , carries a CVSS score of 7.5, indicating high severity. It affects versions from 12.2.3 through 12.2.14. "Easily exploitable vulnerability allows an unauthenticated attacker with network access via HTTP to compromise Oracle Configurator," according to a description of the flaw in the NIST's National Vulnerability Database (NVD). "Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Configurator accessible data." In a standalone alert, Oracle said the flaw is remotely exploitable without requiring any authentication, making it crucial that users apply the update as soon as possible. The company, however, makes no mention of it being exploited in the wild. Oracle's Chi...

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...

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...

Cybersecurity researchers have disclosed details of an active malware campaign called Stealit that has leveraged Node.js' Single Executable Application (SEA) feature as a way to distribute its payloads. According to Fortinet FortiGuard Labs, select iterations have also employed the open-source Electron framework to deliver the malware. It's assessed that the malware is being propagated through counterfeit installers for games and VPN applications that are uploaded to file-sharing sites such as Mediafire and Discord. SEA is a feature that allows Node.js applications to be packaged and distributed as a standalone executable, even on systems without Node.js installed. "Both approaches are effective for distributing Node.js-based malware, as they allow execution without requiring a pre-installed Node.js runtime or additional dependencies," security researchers Eduardo Altares and Joie Salvio said in a report shared with The Hacker News. On a dedicated website, the...
