韩国网络安全公司 Genians 最新研究称,朝鲜关联黑客组织 Kimsuky 已搭建 3 套本地 AI 环境,准备将其用于针对加密货币和金融公司的网络攻击。相关工具部署在本地设备上,不依赖外部云服务。

本地模型已进入准备阶段

Genians 表示,Kimsuky 使用 Ollama、GPT4All 和 Msty 搭建本地大模型环境,并收集了可将模型嵌入软件的库与框架。研究人员还发现,该组织准备了 AI 编程助手 Cursor 和语音转文字工具。

报告称,本地运行模型的直接作用,是避免将攻击计划、样本或目标信息发送给第三方 AI 服务商。相关环境还支持检索增强生成,可让操作者向模型补充资料,用于更具体的任务执行。

Kimsuky 当前重点不是自研新模型,而是把现成的开源工具用于恶意软件开发、数据分析和攻击自动化。Genians 认为,这类活动已不只是零散测试,而是在持续向实战能力靠拢。

钓鱼内容瞄准加密与金融公司

除代码和自动化用途外,Kimsuky 也被指继续利用生成式 AI 制作钓鱼材料,主题集中在加密资产、投资策略和金融科技服务。研究人员发现,一些文件高度模仿韩国一家 AI 投资平台的公开材料。

这些文件在语言、排版和设计上更接近正式商业文档。报告认为,这意味着攻击者不再只依赖粗糙邮件,而是能围绕目标行业制作更像真实业务文件的内容,从而提高诱骗成功率。

朝鲜组织持续渗透加密行业

近期多份研究都显示,朝鲜关联组织仍在扩大对加密行业的攻击面。JUMPSEC 今年 7 月称,另一支朝鲜关联组织 BlueNoroff 曾伪造 Zoom 和 Microsoft Teams 会议页面,在投放恶意软件前先识别受害者是否使用以太坊钱包、Solana 工具及 MetaMask 等扩展。

同月,Drop Site News 报道称,Consensys 曾在发现一名与朝鲜有关的顾问进入内部系统后,短暂停止产品发布。公司随后终止其访问权限,并表示调查未发现资产或数据被盗,也未发现恶意代码影响用户安全。

Ketman Project 的另一项研究还识别出约 100 名疑似朝鲜 IT 人员,他们以虚假身份活跃在 53 个加密和 Web3 项目中。在相关活动被发现前,这些人员所在的代码仓库已有 62 个拉取请求被项目合并。

2025 年失窃金额超 20 亿美元

Chainalysis 此前数据显示,2025 年朝鲜黑客窃取的加密资产约为 20.2 亿美元,其中大部分来自 2025 年 2 月对 Bybit 的攻击。该事件中,超过 40 万枚 ETH 及质押 ETH 被盗,价值约 15 亿美元。

Bybit 已在美国联邦法院起诉朝鲜、其侦察总局以及 Lazarus Group。法院还对部分被盗资产发出初步禁令,在民事诉讼推进期间限制相关资产被转移或出售。

随着被盗资产被换成比特币并分散到数千个钱包,链上追踪难度也在上升。Bybit 首席执行官 Ben Zhou 曾在 2025 年 4 月表示,已有 27.6% 的被盗资金无法继续追踪。

Memory Tightness Spreads to Consumer Electronics: Why Is Apple Evaluating ChangXin DRAM for Some Devices in the Chinese Market?
An unremarkable memory chip is usually not something that would make headlines in the supply chain. It's more like a standard component: as long as it's available, usable, and delivered on time, that's sufficient. However, when reports mention that "Apple is testing memory chips from ChangXin Memory (CXMT) in its iPhone and MacBook product lines," this standard component suddenly becomes significant—not because of its novelty, but because Apple is willing to use it in its most critical product lines for testing.
