Researchers Null-Route Over 550 Kimwolf and Aisuru Botnet Command Servers

Jan 14, 2026 Botnet / Network Security
The Black Lotus Labs team at Lumen Technologies said it null-routed traffic to more than 550 command-and-control (C2) nodes associated with the AISURU/Kimwolf botnet since early October 2025. AISURU and its Android counterpart, Kimwolf, have emerged as some of the biggest botnets in recent times, capable of directing enslaved devices to participate in distributed denial-of-service (DDoS) attacks and relay malicious traffic for residential proxy services . Details about Kimwolf emerged last month when QiAnXin XLab published an exhaustive analysis of the malware, which turns compromised devices – mostly unsanctioned Android TV streaming devices – into a residential proxy by delivering a software development kit (SDK) called ByteConnect either directly or through sketchy apps that come pre-installed on them. The net result is that the botnet has expanded to infect more than 2 million Android devices with an exposed Android Debug Bridge (ADB) service by tunneling through residentia...

China-Linked UAT-7290 Targets Telecoms with Linux Malware and ORB Nodes

China-Linked UAT-7290 Targets Telecoms with Linux Malware and ORB Nodes

Jan 08, 2026 Malware / Threat Intelligence
A China-nexus threat actor known as UAT-7290 has been attributed to espionage-focused intrusions against entities in South Asia and Southeastern Europe. The activity cluster, which has been active since at least 2022, primarily focuses on extensive technical reconnaissance of target organizations before initiating attacks, ultimately leading to the deployment of malware families such as RushDrop, DriveSwitch, and SilentRaid, according to a Cisco Talos report published today. "In addition to conducting espionage-focused attacks where UAT-7290 burrows deep inside a victim enterprise's network infrastructure, their tactics, techniques, and procedures (TTPs) and tooling suggest that this actor also establishes Operational Relay Box (ORBs) nodes," researchers Asheer Malhotra, Vitor Ventura, and Brandon White said . "The ORB infrastructure may then be used by other China-nexus actors in their malicious operations, signifying UAT-7290's dual role as an espionage-motiva...

Webinar: Learn How AI-Powered Zero Trust Detects Attacks with No Files or Indicators

Jan 07, 2026 Threat Detection / Endpoint Security
Security teams are still catching malware. The problem is what they're not catching. More attacks today don't arrive as files. They don't drop binaries. They don't trigger classic alerts. Instead, they run quietly through tools that already exist inside the environment — scripts, remote access, browsers, and developer workflows. That shift is creating a blind spot. Join us for a deep-dive technical session with the Zscaler Internet Access team. They will reveal how to unmask "hidden-in-plain-sight" tactics, why traditional defenses fall short, and exactly what needs to change. Secure your spot for the live session ➜ In this session, experts will cover: "Living off the Land" Attacks: These use trusted system tools like PowerShell, WMI, or remote desktop.

Fix SOC Blind Spots: See Threats to Your Industry & Country in Real Time

Dec 17, 2025 Threat Intelligence / Endpoint Security
Modern security teams often feel like they're driving through fog with failing headlights. Threats accelerate, alerts multiply, and SOCs struggle to understand which dangers matter right now for their business. Breaking out of reactive defense is no longer optional. It's the difference between preventing incidents and cleaning up after them. Below is the path from reactive firefighting to a proactive, context-rich SOC that actually sees what's coming. When the SOC Only Sees in the Rear-View Mirror Many SOCs still rely on a backward-facing workflow. Analysts wait for an alert, investigate it, escalate, and eventually respond. This pattern is understandable: the job is noisy, the tooling is complex, and alert fatigue bends even the toughest teams into reactive mode. But a reactive posture hides several structural problems: No visibility into what threat actors are preparing. Limited ability to anticipate campaigns targeting the organization's sector. Inability to adjust defenses...
