Kernel Panic 独家获得的新研究显示,黑客已开始将人工智能功能加入一种新型信息窃取恶意软件,使系统能够自动画像受害者,并迅速筛选出最高价值的目标及其信息。由于恶意软件内部自称的名称,该恶意软件被命名为“Volta-Autodoxer”,思科塔洛斯研究人员的发现揭示了商业大语言模型如何被用于增强和提升既有恶意软件类型的能力。

New research shared exclusively with Kernel Panic shows that hackers have started adding AI functionality into a new strain of infostealer malware, making it possible for the system to automatically profile victims and quickly surface the highest value targets and their information. Dubbed “Volta-Autodoxer” because of how the malware refers to itself internally, the finding by Cisco Talos researchers sheds light on the ways that commercial LLMs are being used to augment and enhance the capabilities of established types of malware.

信息窃取恶意软件常隐藏在伪造软件中,旨名副其实地从受感染机器中窃取用户名、密码、身份验证令牌、Cookie、信用卡数据等信息。近年来许多重大数据泄露事件——包括涉及AT&T和Ticketmaster的广泛Snowflake关联泄露,以及迪士尼一太字节数据被盗事件——均源于黑客利用信息窃取恶意软件收集的详情访问目标。总体而言,近年来该类恶意软件已被用于窃取数亿条凭证。

Often hidden in counterfeit software, infostealers are designed to live up to their name, grabbing usernames, passwords, authentication tokens, cookies, credit card data, and more from infected machines. Many of the biggest data breaches in recent years—from the widespread Snowflake-linked breaches that included AT&T and Ticketmaster to the theft of a terabyte of Disney data—have resulted from hackers accessing targets using details gathered by infostealers. Overall, the malware has been used to steal hundreds of millions of credentials in recent years.

“Volta作为窃取软件相当成熟,它在收集内容上撒了相当宽的网,”思科塔洛斯安全研究员瑞安·费特曼说。“它将所有这些内容汇总,最终生成一个可发送给几个大语言模型的序列化档案。它要求模型充当情报分析师,并对受害者生成带有结构化引用支持的评估。这就像一个优先级排序和分析功能。”塔洛斯使用其新的CAIRN框架标记了该恶意软件,该框架旨在识别融入人工智能功能的黑客工具。费特曼指出,塔洛斯未追踪Volta是否已在野外被使用。

“Volta is pretty mature as a stealer. It casts a pretty wide net for what it collects,” says Ryan Fetterman, a security researcher at Cisco Talos. “It compiles all of those things together, ultimately producing a serialized dossier that it can send to a couple LLM models. It’s asking the model to act like an intelligence analyst and produce structured citation-backed assessment of the victim. It’s like a prioritization and analysis function.”Talos flagged the malware using its new CAIRN framework, built to identify hacking tools that incorporate AI capabilities. Fetterman notes that Talos did not track whether Volta has been used in the wild.

Volta 的传统信息窃取功能强大,似乎针对的是拥有丰富数字生活的年轻网民。它会扫描浏览器中存储的密码、Microsoft OAuth 令牌、Cookie、支付卡以及加密钱包助记词,还会获取活跃的 Discord、Telegram、Steam 和 Roblox 会话。随后,恶意软件会利用第一轮收集到的结果进行第二次、更深入的扫描。通过查看目标的 Gmail 或其他中心账户,Volta 能利用来自 UberEats、DoorDash 等服务的收据和订单历史等数据,构建受害者的更完整画像,包括其位置和行为习惯。

Volta’s traditional infostealer capabilities are powerful and seem to be geared toward targeting younger internet users with robust digital lives. It sweeps for passwords stored in browsers, Microsoft OAuth tokens, cookies, payment cards, and crypto wallet seed phrases, but also active Discord, Telegram, Steam, and Roblox sessions. Then the malware does a second, deeper sweep using its first-round findings. By looking through the target’s Gmail or another central account, Volta builds a fuller picture of the victim, their location, and their habits using data like receipts and order history from services including UberEats and DoorDash.

完成上述所有步骤后,恶意软件会将发现的情报输入 AI 工具进行分析,使用 OpenRouter 这一可向多个不同 AI 提供商发送提示的服务。Volta 默认将请求发送给 Anthropic 的 Claude Opus 4.6。但显然为了防止模型的安全防护阻断活动,Volta 设有后备方案,先切换到中国开源模型 Moonshot AI 的 Kimi K2,若仍失败,则使用 Google 的 Gemini 2.5 Flash。构建后备方案并依赖成本较低的旧代模型是攻击者常用的技术手段。

Once all of this is done, the malware feeds its findings into AI tools for analysis using OpenRouter, a service that can send prompts to multiple different AI providers. Volta defaults its requests to Anthropic’s Claude Opus 4.6. But apparently preparing for the possibility that the model’s guardrails could block the activity, Volta is built with fallbacks to the Chinese open weight Moonshot AI Kimi K2 and, if that fails, Google’s Gemini 2.5 Flash. Building in fallbacks and relying on cost-effective, older-generation models are common techniques among attackers.

Volta 的制作者在向任何分析收集数据的 LLM 提供的指令中,加入了一段 240 字的提示,其中包括项目符号和编号列表。提示中写道:“你是一名取证情报分析员,正在从结构化证据包中起草目标评估。”该提示指示聊天机器人生成关于该人的“执行摘要”、其行为细节、“价值评估”,以及对其“操作安全”的概括。提示还要求聊天机器人“跨领域连接线索”,例如检查某人的 Wi‑Fi 密码是否与其姓氏相符。提示最后写道:“深入分析,而非广泛覆盖”。

Volta’s creators included a 240-word prompt, including bullet points and a numbered list, as part of their instructions to any LLM analyzing the collected data. “You are a forensic intelligence analyst drafting a target assessment from a structured evidence bundle,” the Volta prompt says. It instructs the chatbot to produce an “executive summary” about the person, details of what they do, “what they’re worth,” and a summary of “their opsec.”It adds that the chatbot should “connect dots across fields,” for example, checking whether someone’s Wi-Fi password matches their last name. “Go deep, not wide,” the prompt says.

“提示词经过非常精心的设计,并未暗示任何明显的恶意意图,”费特曼说。“但他们正在构建一种预期,即在首次请求时可能会遇到模型拒绝。因此,他们计划在链条下行过程中,实现一种故障转移,级联到更宽松的模型。此外,还具备在不使用 AI 的情况下继续使用植入物的能力。AI 调用属于锦上添花,但恶意软件即使没有 AI 也能正常工作。”

“The prompt is pretty carefully crafted not to imply anything overtly malicious,” Fetterman says. “But they’re building in the expectation to potentially hit model refusals at first request. And so they plan for failover kind of cascading to more permissible models as they go down the chain. And there’s also the capability to still use the implant without the AI. The AI calls are kind of above and beyond, but the malware will still work without it.”

一些低级网络犯罪分子和骗子抱怨,AI 生成的低质量内容充斥网络犯罪论坛,但安全研究人员越来越多地发现,其他黑客正在利用大语言模型进行编码任务或分析大量被盗信息。例如,威胁情报公司 Crowdstrike 的研究人员最近告诉《连线》杂志,他们发现四个不同的黑客组织——运营语言分别为中文、西班牙语和英语、印尼语以及俄语,技术水平各异——正在使用 AI 工具攻破全球数十个目标,包括政府机构以及医疗保健、零售和旅游行业的企业。

Some low-level cybercriminals and scammers have complained about AI slop filling up cybercrime forums, but security researchers are increasingly discovering other hackers using LLMs for coding tasks or analyzing troves of stolen information. Researchers at threat intelligence firm Crowdstrike, for example, recently told WIRED they had seen four distinct hacking groups with varying sophistication—operating in Chinese, Spanish and English, Indonesian, and Russian—using AI tools to compromise dozens of targets around the world, including government entities and businesses in health care, retail, and travel.

思科的费特曼表示,Volta 中包含一些线索,表明它可能是为出售给一系列攻击者而构建,而不是为某个特定行为体的行动开发的。虽然该恶意软件的核心仍然是传统的信息窃取程序,但 AI 的扩展预示着未来将出现更具侵略性和更阴险的活动。

Cisco’s Fetterman says Volta contains some clues that it may have been built to sell to a range of attackers rather than being developed for one specific actor’s campaigns. And while the malware at its core is still a traditional infostealer, the AI expansion foreshadows even more invasive and sinister activity in the future.

“如果你能更快地识别高价值目标,那么你使用其凭证或利用被盗令牌进行身份验证的机会可能会更大,而如果你需要亲自进行分类处理,可能就没有这么多机会了,”费特曼说,他提到的事实是身份验证令牌会过期,密码也可以更改。“我们看到,更先进的功能正变得可供低水平攻击者使用。这既很有趣,也令人不安。”

“If you’re able to identify your high-value targets faster, you probably have a better chance of using their credentials or authenticating using stolen tokens more often than maybe you would have if you had to do that triage yourself,” Fetterman says, referencing the fact that authentication tokens expire and passwords can be changed. “We’re seeing more advanced capabilities accessible to lower-level sophistication attackers. It’s really interesting and disturbing.”
