经常有人问，我想分析的恶意样本，可是这些样本要从哪儿下载呢？看到别人的分析报告，里面有IOC信息和样本MD5，我也想分析一下，但这些样本从哪里下载？简单给大家谈谈一般恶意样本可以从哪些渠道得来？ 

如果你身在安全公司，有客户端类的安全产品，一般从下几个渠道可以获取：

(1)一些客户端收集用户的样本，然后保存到样本TOP库，从黑灰库中找可疑样本进行分析，说不定就可以找到惊喜

(2)用户反馈的一些样本，或你帮用户解决安全问题自己从用户电脑上收集回来的样本

(3)有些公司会有一些安全论坛，用户也会上传一些样本到论坛上，定期去查看分析

(4)如果公司有VT帐号，可以从VT上去下载相关的样本

(5)可以从内部的一些监控系统爬虫系统中找到新的样本或变种样本

如果没有客户端产品，一般都是从客户反馈收集的样本进行分析处理，或者从一些开源的样本下载网站，以及与其它公司购买交换而来

如果你不在安全公司工作，可以从以下几个渠道获取：

(1)国外样本分享网站，如：

3ecK9s2c8@1M7q4)9K6b7g2)9J5c8W2)9J5c8X3y4G2L8Y4c8S2k6$3W2G2k6s2g2E0M7q4)9J5k6h3u0D9L8$3N6K6M7r3!0@1i4K6u0W2j5$3!0E0i4K6t1$3L8X3u0K6M7q4)9K6b7R3`.`.

(2)Github上去搜malware， 如：1a2K9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6Y4K9i4c8Z5N6h3u0Q4x3X3g2U0L8$3#2Q4x3V1k6J5M7$3S2A6M7s2m8Q4x3V1k6S2N6$3g2K6L8$3#2W2i4K6u0V1L8h3q4D9N6$3q4J5k6g2)9J5k6r3q4F1j5h3I4&6M7$3W2K6i4K6t1$3L8X3u0K6M7q4)9K6b7W2!0q4c8W2!0n7b7#2)9^5z5q4!0q4y4q4!0n7c8q4!0m8x3q4!0q4y4g2)9^5c8W2!0m8c8W2!0q4y4q4!0n7b7W2!0m8y4g2!0q4y4W2)9^5z5g2!0n7c8g2!0q4y4g2)9^5z5q4!0n7x3q4!0q4y4g2!0n7c8g2)9^5z5q4!0q4y4g2!0m8y4q4)9&6b7g2!0q4y4W2)9^5x3#2!0n7x3#2!0q4z5q4!0m8y4W2)9^5x3g2!0q4y4#2)9&6b7g2)9^5y4q4!0q4c8W2!0n7b7#2)9^5z5b7`.`.

(3)加入Google Malware邮件组或一些TG组，里面会有人分享样本，如：mobilemalware@googlegroups.com

(4)关注一些国外安全研究人员的Twitter，每天都会分享很多新的变种样本 

(5)关注一些国外大的安全公司的博客，如：

这上面会定期更新一些恶意样本的分析报告，有时候会放样本，没有样本可以通过HASH自己Google去找

(6)国内一些安全论坛以及安全媒体，也会有很多人上传一些样本，如看雪，卡饭，吾爱破解，FreeBuf等

(7)国内一些安全公司的论坛，不知道还有几个在持续运营了。。。。如：360杀毒论坛，金山杀毒论坛，电脑管家论坛，瑞星杀毒论坛等

(8)如果你有钱任性，完全可以自己去买个VT帐号，里面的样本你这辈子都分析不完

下面给大家分享一些在线或开源沙箱以及一些流行样本下载链接，大部分的在线沙箱都支持下载样本，不过有些是免费的，有些需要注册，有些是收费的，有些需要积分等等

以上都是个人经验总结，相关的渠道和安全论坛网站还有很多，如果对恶意样本分析感兴趣的，可以去下载这些样本进行研究，可以发现一些不一样的东西

从这些网站上下载的所有样本仅供自己研究学习之用，不要传播，严禁用于非法用途，否则后果自负!

现在大多数的安全问题都是通过恶意软件进行攻击的，如果你对恶意软件感兴趣，想研究学习各类恶意样本的分析技术，想与一些专业的安全分析师与漏洞研究专家交流，欢迎加入知识星球：安全分析与研究，分享各种安全技术：应急响应、恶意样本分析、渗透测试、漏洞研究、移动安全等

欢迎关注微信公众号：安全分析与研究，会不定期分享各种安全知识与技术，因为专注，所以专业！

安全的路很长，贵在坚持......
