Manic Android Malware Steals PINs via Transparent Overlay and Relays Data Through Nearby Infected Devices

A newly identified Android malware strain named Manic merges banking trojan, spyware, and remote access capabilities. The threat has been active since at least February 2026 and continues to receive updates that add anti-analysis features, in-memory code loading, and lock-screen credential theft. Manic monitors 169 financial, messaging, and government applications while using a transparent overlay on legitimate numeric keyboards to capture PINs without displaying a full fake banking screen. Stolen data can be forwarded through other compromised nearby devices even when the original phone lacks internet connectivity. Operators also leverage WebRTC sessions for live screen viewing and remote interaction. The malware additionally functions as a keylogger, intercepts SMS and notifications, and collects passwords, one-time codes, and recovery phrases. Security researchers recommend avoiding unknown APKs and scrutinizing requests for Accessibility Services or broad device control permissions.

A new Android malware called Manic combines features of a banking trojan, spyware, and remote device control. The threat stands out for its ability to exfiltrate stolen data through other infected phones nearby, even when the original device has no direct internet access.

Manic has been active since at least February 2026 and remains under active development. In July, newer versions introduced additional anti-analysis techniques, in-memory code loading, and mechanisms aimed at stealing lock-screen credentials.

The malware monitors 169 applications, including banks, payment services, cryptocurrency wallets and exchanges, authenticators, messengers, browsers, and government digital identity platforms.

One of its most unusual capabilities allows PIN capture without showing a complete fake banking screen. Manic places a transparent layer over the legitimate application's numeric keypad, records the victim's touches, and then replays the same commands using Android Accessibility Services.

The threat also operates as a keylogger, intercepts SMS messages and notifications, and can harvest passwords, temporary codes, and recovery phrases. WebRTC sessions further enable operators to view the screen and interact remotely with the compromised device.

Users should avoid installing APKs from unknown sources and remain cautious of applications requesting Accessibility Services, notification access, or broad device control without a clear need.

Yoba Campaign Uses Signed ChatGPT and Claude Binaries for DLL Sideloading and XMRig Deployment

Researchers at Check Point Research have uncovered the Yoba malware campaign that distributes fake desktop clients for ChatGPT and Claude through GitHub repositories. The attackers bundle legitimate signed executables from OpenAI and Anthropic with a malicious DLL that gets loaded via classic sideloading. Once executed, the loader establishes persistence using the Windows Task Scheduler and retrieves additional payloads through Telegram, DNS over HTTPS, and the Catbox file hosting service. The campaign ultimately deploys the XMRig cryptominer, which pauses mining activity when user interaction is detected to avoid detection. No compromise of OpenAI or Anthropic infrastructure was found; the attackers simply repurpose the companies' signed binaries and reputation. The operation primarily targets home users and small-to-medium businesses with Windows systems.

uCreator Spyware Infiltrates Modified Telegram, WeChat and GCash Builds on Android

Security researcher Ovi has published a detailed analysis of uCreator, also known as YingGai, a commercial Android spyware platform designed for surveillance and remote app control. The malware intercepts messages, verification codes and account data directly inside legitimate applications without requiring root privileges. Infection vectors include tampered Telegram, WeChat and GCash APKs distributed through unofficial sources, as well as the Onion Box container that launches the target app inside a controlled environment. Once active, uCreator hooks into the host process, reads Telegram’s local message database through client interfaces, captures two-factor authentication passwords and hides its own session from the user. The operation is supported by cloud-based command panels and exposed GitLab repositories that revealed server-side code and development history. Compatibility problems have been noted on Android 17, and the total number of victims remains unknown.

Researchers Deploy Cowrie Honeypot Disguised as NVIDIA H100 Server to Study SSH Botnet Tactics

A cybersecurity team set up a realistic Cowrie honeypot on a fake server equipped with four NVIDIA H100 GPUs, 128 AMD EPYC cores, and terabytes of storage to observe what SSH brute-force bots actually do after gaining access. The trap used a custom StickyAuth module that allowed entry only after several failed attempts and locked in the successful credential pair per IP address. Over the first 12.5 hours the system recorded 1,846 connections from 126 unique IPs, 175 successful logins, and 1,524 commands executed, with the majority of activity traced to a single botnet linked to the Outlaw group. The attackers deployed SSH keys signed mdrfckr, changed the root password, killed competing processes, installed cron jobs, and downloaded a mining archive called dota3 containing an IRC backdoor and its own SSH scanner. The researchers also identified three realism issues in the base Cowrie setup—limited grep flags, outdated filesystem paths in Debian 12, and inconsistent hostname reporting—and patched them to keep sophisticated bots engaged longer. An auxiliary LLM service later summarized each session in Telegram for easier analysis.
