AI overview

Cisco Talos published an analysis on October 31, 2026, disclosing that the Windows infostealer VOLTA (self-named VOLTA-AUTODOXER), after stealing browser passwords, cookies, payment cards, cryptocurrency wallet mnemonics, session tokens for Discord and Telegram, SSH and cloud configurations, organizes the victim's data into a structured evidence package, calls large models via OpenRouter, ranks them by monetization value in low, medium and high tiers, and also assesses security habits. Its default model is Anthropic's Claude Opus 4.6; when it encounters a refusal, it falls back in order to Moonshot AI's Kimi K2 and Google's Gemini 2.5 Flash, trying at most three models, and may also skip the AI step entirely. The trojan also uses the stolen Gmail session to search shopping receipts to confirm the address, employer and other information, and self-deletes after running. Talos believes it is sold as a builder and found no attacker-owned server.

    AI-driven infostealer VOLTA-AUTODOXER picks out the most valuable parts of stolen data

    Cisco Talos found a Windows infostealer named VOLTA-AUTODOXER that organizes stolen data into a profile and sends it to a large model, asking it to rank the victim's assets by ease of monetization and label them low, medium or high. The malware first steals browser passwords, cookies, payment cards, cryptocurrency wallet seed phrases, Microsoft OAuth tokens and SSH keys as usual, then uses the stolen sessions to check Gmail shopping receipts and UberEats and DoorDash orders to fill in information such as home address and employer. Requests are sent by default via OpenRouter to Claude Opus 4.6, and if refusal wording appears in the reply they are forwarded in turn to Kimi K2 and Gemini 2.5 Flash; Talos believes this multi-model design is meant to anticipate refusals. The malware deletes itself after running and connects only to third-party endpoints; its configuration template leaves six slots for the builder to fill in, which researcher Fetterman says suggests it is sold customized to order.

    AI valuation: the VOLTA infostealer uses LLMs to grade victims

    CSA research notes interpret Cisco Talos's analysis of the Windows infostealer VOLTA, which after stealing credentials can send the victim's profile to commercial large language models to automatically assess its monetization value and security-habit weaknesses. The malware calls models via OpenRouter, defaulting to Claude Opus 4.6, and upon detecting refusal wording falls back in sequence to Kimi K2 and Gemini 2.5 Flash; the profile contains address, employer, inferred birth year and payment card information, with the address confirmed via receipts in the victim's Gmail. The notes hold that AI has entered the post-theft monetization stage rather than only code generation, potentially letting attackers pick high-value targets from the more than 50 million stolen logs on underground channels in 2025 counted by Flare, and that a single model's refusal cannot stop attackers using aggregators. The notes also state that evidence is limited, that Talos analyzed only a single sample, and that the distribution vector and actual harm are unconfirmed.

    New malware VOLTA-AUTODOXER uses AI to rank stolen data by value

    Cisco Talos researchers disclosed a Windows infostealer named VOLTA-AUTODOXER that calls large language models through OpenRouter to assess and rank stolen victim data by monetization value. The trojan steals browser passwords and cookies, payment card information, crypto wallet seed phrases, Discord, Telegram, Steam and Roblox session tokens, SSH and cloud keys, and compiles victim profiles including home address, employer, last four digits of credit cards and Roblox account valuation, and also searches the victim's Gmail receipts to corroborate the address. The AI analysis prefers Anthropic's Claude Opus 4.6, falling back to Moonshot AI's Kimi K2 or Google's Gemini 2.5 Flash when refused, rotating through at most three models, and uses a 240-word system prompt to have the model act as a forensic intelligence analyst, outputting a list of assets ranked by monetization potential and an assessment of the victim's security posture.

    New VOLTA infostealer uses Claude, Gemini and Kimi to rank victims by economic value

    Cisco Talos disclosed a Windows infostealer named VOLTA (VOLTA-AUTODOXER) that organizes stolen victim data into an evidence package and hands it to large models, which rank it by monetization value and sort it into low, medium and high tiers. The malware calls models through OpenRouter, uses Anthropic's Claude Opus 4.6 by default, and falls back to Moonshot AI's Kimi K2 and Google's Gemini 2.5 Flash when it encounters a refusal, chaining up to three models; its 240-word system prompt asks the model to play a forensic intelligence analyst and output a victim net-worth and OPSEC assessment based only on the evidence package. The theft scope includes browser passwords and cookies, payment cards, crypto wallet seed phrases, sessions such as Discord and Steam, Microsoft OAuth tokens, SSH and cloud provider keys, Wi-Fi configurations and screenshots, and it uses stolen sessions to access Gmail receipts to verify addresses.

    New AI-driven malware VOLTA steals passwords and cryptocurrency wallets to identify high-value victims

    Cisco Talos discloses the Windows infostealer VOLTA, which steals passwords and cryptocurrency wallets and then uses AI to profile victims and identify high-value targets. The stolen data is passed via OpenRouter to models to generate asset value rankings and assessments of security habits; its AI calls claude-opus-4.6 by default, and can switch to kimi-k2 and gemini-2.5-flash if refused.

    VOLTA malware steals Gmail and Discord sessions, then uses AI to generate victim profiles

    Cisco Talos disclosed a new Windows infostealer, VOLTA: after stealing login sessions for Gmail, Discord and others, it calls AI via OpenRouter to generate an asset valuation report on the victim. The workflow uses Claude Opus 4.6 by default, and when refused, falls back in order to Kimi K2 and Gemini 2.5 Flash; the report rates asset value as low, medium or high and assesses password habits. Talos believes it is sold as a builder, and no attacker-owned server has been found.

    VOLTA infostealer asks AI which victims are worth targeting

    Cisco Talos analyzed a new Windows infostealer named VOLTA (self-named VOLTA-AUTODOXER) that, after stealing data, calls large language models to assess and rank victim value. After running, the malware self-deletes, steals browser passwords, cookies, payment card information, sessions such as Discord and Telegram, and Microsoft OAuth tokens, and must bypass Chrome's App-Bound Encryption. It also uses the victim's session to search Gmail for shopping receipts to confirm the home address, sends the evidence package via the model routing service OpenRouter to large models, and asks for an asset inventory graded by monetization potential and an assessment of the victim's security habits, calling Anthropic's Claude Opus 4.6 by default and, upon detecting a refusal, switching in turn to Moonshot AI's Kimi K2 and Google's Gemini 2.5 Flash.

    New AI-driven Windows malware VOLTA-AUTODOXER hands stolen data to Claude, which ranks the victim's assets by value, then deletes itself

    Cisco Talos reported finding a self-deleting Windows infostealer named VOLTA-AUTODOXER that, after stealing data from the victim's computer, by default calls Anthropic's Claude to organize the stolen information into a structured evidence package and has the model list the victim's belongings by monetization value. The malware's prompt instructs the model to act as a forensic intelligence analyst and to answer directly, specifically and accurately; if the model refuses, it can switch to other models or even skip the AI step entirely. Its theft scope includes browser passwords, cookies, saved payment cards, Thunderbird and Outlook mail configurations, Roblox accounts, Microsoft OAuth tokens, screenshots, and SSH and cloud provider configuration files; saved Wi-Fi passwords are obtained in plaintext; for cryptocurrency wallets it does not merely copy them but attempts to crack their vaults directly. It also builds a victim profile, including geolocation and home address, employer and employer domain, inferred birth year, document author metadata and the last four digits of payment cards.

    Volta malware: having Claude assess how much each victim is worth

    Cisco Talos published an analysis on October 31, disclosing a Windows infostealer that calls itself VOLTA-AUTODOXER; after stealing passwords, cookies and cryptocurrency wallets, it sends the victim's profile to commercial AI models, having the models act as forensic intelligence analysts to output asset valuations and assessments of security habits. The default model is Anthropic Claude Opus 4.6 called via OpenRouter, and after detecting refusal phrases it falls back in order to Moonshot AI's Kimi K2 and Google's Gemini 2.5 Flash. The analysis is based on a single sample first discovered on October 11, with no known attack campaign or victims, and whether the models actually cooperate has not been tested; Talos speculates that the trojan is sold on a builder model, with AI valuation becoming a product feature that lets low-skill buyers also obtain target assessments.

    Cisco Talos details the stage in which VOLTA infostealer malware uses an LLM to rank victims

    Cisco Talos researcher Ryan Fetterman published an analysis on October 31, 2026, detailing the stage in which the Windows infostealer malware VOLTA-AUTODOXER, after stealing credentials, uses an LLM to rank victims' monetizable assets. The malware extracts multiple types of credentials, including browser, messaging and cloud configurations, and uses stolen Gmail tokens to retrieve receipts corroborating addresses, organizing the evidence into JSON and sending it to OpenRouter's chat completions endpoint. Talos says its default model is anthropic/claude-opus-4.6, falling back in order to moonshotai/kimi-k2 and google/gemini-2.5-flash, with a temperature of 0.2; when a refusal appears in the reply, it switches to the next model, trying at most three. The inference is performed on the victim's endpoint and network connection, and the results are only exfiltrated afterward.

    Cisco Talos describes the victim grading stage in the LLM infostealer VOLTA

    Cisco Talos researcher Ryan Fetterman published an analysis on October 31, 2026 of the Windows infostealer VOLTA-AUTODOXER, malware that after completing a round of credential theft calls an LLM to grade victims by monetization value. In a single run, VOLTA collects credentials and cookies from Chromium, Firefox and Thunderbird, payment cards, session tokens for Slack and Discord and others, SSH and cloud service configurations, Wi-Fi profiles and screenshots, and performs cracking against wallet vaults; it then uses stolen Gmail tokens to search receipts from Amazon, DoorDash, Uber Eats and others to confirm the home address, then checks Uber Eats and DoorDash order history, queries Roblox inventory via Rolimons.com, and compiles everything into Identity_Report.txt and serializes it as JSON.

    AI Evaluation: Model-Driven Victim Prioritization in the VOLTA Infostealer Trojan

    Cisco Talos disclosed that the infostealer trojan VOLTA, after stealing credentials, sessions and cryptocurrency wallets, organizes victim data into structured data packages and sends them to large models to rank victims' assets by monetization value. The trojan calls models through OpenRouter, using anthropic/claude-opus-4.6 by default; when refusal expressions such as "I can't" appear in the reply, it switches in turn to kimi-k2 and gemini-2.5-flash, trying at most three models; the temperature is fixed at 0.2. The system prompt asks the model to act as a "forensic intelligence analyst," output a list of asset values labeled low, medium and high, and assess the victim's security habits, then supplement the data with stolen Gmail receipts, UberEats and DoorDash orders, and Discord and Roblox account data. Talos noted that the trojan self-deletes and has no attacker-owned infrastructure; the program reserves six replaceable configuration slots, filled in at compile time, and the authors infer that this is a sell-by-custom-compilation model.

    New infostealer trojan Volta-Autodoxer uses AI to automatically screen high-value victims

    Cisco Talos researchers discovered a new infostealer trojan, Volta-Autodoxer, which organizes stolen credentials into serialized profiles and hands them to a commercial LLM to automatically generate cited victim assessments, so as to quickly identify high-value targets. By default, the trojan calls Anthropic's Claude Opus 4.6 via OpenRouter, and has a preset fallback to Moonshot AI's Kimi K2 when the model refuses, then to Google's Gemini 2.5 Flash; its built-in prompt of about 240 words asks the model to act as a forensic intelligence analyst and produce a victim's "net worth" and opsec assessment. Talos flagged this sample with its newly released CAIRN framework, but did not track whether the trojan has been used in the wild.
