Dolphin X Malware Adds AI Profiler to Rank and Prioritize High-Value Victims After Infection

Dolphin X is a newly identified Windows infostealer and remote access trojan that integrates an AI Profiler component designed to score infected machines and generate priority rankings for operators. The profiler analyzes telemetry from compromised systems, including application usage, browser domains visited, and installed software, to produce daily summaries that help attackers focus resources on the most valuable targets such as those with cloud access or sensitive tools. Dolphin X claims compatibility with over 300 applications, explicitly covering nine Chromium and Gecko browser families, more than 100 cryptocurrency wallet extensions, 65 desktop wallets, 10 password managers, and over 30 common cloud CLI tools. The malware targets files like .env configurations, SSH keys, cloud access tokens, browser sessions, and cryptocurrency wallet data to accelerate movement from initial credential theft to further compromises in accounts and production environments. Researchers have confirmed the AI Profiler workflow and associated scoring functions in the operator panel, although the underlying AI model itself remains unverified without full analysis of an active sample. The discovery highlights how automated prioritization can significantly shorten the time between mass infections and targeted follow-on attacks, prompting recommendations for reduced local credential storage and enhanced behavioral detection.

Dolphin X is a new infostealer and RAT for Windows that incorporates an AI Profiler capable of scoring infected machines and ordering victims by value. The idea is to accelerate the transition from mass secret theft to subsequent compromises in accounts, cloud services, and production environments.

The novelty of Dolphin X lies not only in what it steals but in whom it decides to target first. This Windows malware, presented as both an infostealer and remote access trojan, includes a component called AI Profiler that classifies compromised machines, assigns scores, and builds a ranking so operators can concentrate time and resources on the most profitable victims.

The profiling relies on telemetry from the infected machine. This includes signals such as application usage, browser-visited domains, and installed software. From this data the attacker panel generates daily summaries and a priority order that reduces the manual triage work typically required after infection waves.

Operators first examine machines offering the greatest potential return, whether through cloud access, technical profiles, or the presence of sensitive tools. The operator panel showcases the product scope with 329 functions spread across 10 categories, a figure typical of commercial malware families that advertise extensive catalogs even before real-world campaigns are observed.

In the credential theft section, Dolphin X claims compatibility with more than 300 applications, explicitly mentioning nine Chromium and Gecko browser families, over 100 cryptocurrency wallet extensions, 65 desktop wallets, 10 password managers, and more than 30 CLI tools commonly used in cloud environments.

Among the declared targets are .env files, SSH keys, cloud access tokens, browser sessions and credentials, plus information linked to cryptocurrency wallets. The existence of the AI Profiler workflow has been verified inside the panel along with internal strings and functions related to data collection and score calculation.

However, the actual AI engine responsible for generating the valuations has not yet been confirmed. Full analysis of an active sample running on a victim machine is still needed to determine which model is used, whether external services are called, or whether the system relies on rules and weightings given an attention-grabbing name.

No active distribution campaign or specific lures have been confirmed either. This gap does not reduce the risk. The combination of secret theft and automatic prioritization can drastically shorten the time until the next stage, such as account takeover, repository access, movement into production environments, or abuse of cloud infrastructure.

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.
