勒索病毒全球蔓延 “背锅侠”比特币两周涨63%

《中国经济周刊》记者 宋杰 | 上海报道

5月25日,国内比特币的最高价格达到21122元,创下历史新高。今年以来,比特币的交易价格不断上涨,累计最高涨幅已经超过150%。5月中旬以来比特币的涨势更是惊人,短短两个星期,价格飙涨了63%。

比特币新一轮价格暴涨,或许与一场肆虐全球的计算机勒索病毒相关。

“你的电脑已经被锁,文件已经全部被加密,除非你支付价值等额300美元的比特币,否则你的文件将被永久删除。”5月12日,一场利用Windows网络共享协议疯狂传播的蠕虫病毒突然间席卷全球,很快波及100多个国家,至少7.5万台电脑被感染。

需要注意的是,受害者需要支付的赎金,既不是美元也不是人民币,而是比特币。一时间,很多人纷纷指责比特币成了攻击者的“帮凶”。

那么“勒索病毒”为何要选比特币作为赎金呢?

比特币为何成黑客“帮凶”?

此次勒索病毒攻击,攻击者还很“体贴”地将勒索信息翻译成了28种语言,文字内容还循循善诱:就算老天爷来了也不能恢复这些文件,最好3天之内付款,过期就会翻倍。

然而,黑客在3天内仅收到价值6万美元的比特币。虽然这与蠕虫病毒本身的紧急开关有关系,但实际上,对于大多数普通人而言,比特币是什么都不清楚,更不用说用比特币去缴纳赎金了。

那么问题来了,黑客为何选择比特币做赎金?

比特币——最初由中本聪在2009年提出的一种电子货币。与现有的主权国家发行的货币不同,比特币不由央行发放,而是通过公开的算法生成,要想获得比特币,可以通过消耗计算机的算力,“挖矿”获得;或者是通过网络比特币交易市场从拥有比特币的人那里交换得到。从2008年中本聪发表第一篇关于比特币的论文以来,全世界已经“挖出”了超过1200万个比特币。

为什么勒索者要求使用比特币来支付赎金呢?花虾金融CEO段念对《中国经济周刊》记者说,黑客们利用的是比特币的一个设计特征:匿名性。比特币在设计时实现了良好的匿名性,每个人都可以随意创建比特币钱包,而只要知道了对方的比特币钱包地址,任何人都可以将比特币通过网络发送给他。由于比特币的流通不通过任何金融机构,虽然任何人都能看到比特币的流向(从一个钱包转向了另一个钱包),但却很难追踪到真正的接收者是谁。
