新骗局:冒充朋友“微信语音”借钱

2017-08-23 07:55:36   中国经济网

■本报记者 简工博 邬林桦

前一秒明明听到朋友熟悉的声音,下一秒就开始诉苦借钱——“耳听”真的为实吗?日前,包括公安部、上海市公安局在内的多地警方都通过官方微博、微信证实:通过发送语音博取信任继而“借钱”的骗术已在全国多地发生。

声音和相貌一样,具有独特性,这一骗术迷惑人的地方正在于此。骗子如何获得微信好友独一无二的声音自证身份的?打开微信,语音并没有“转发”这一选项,腾讯方面曾公开表示“语音转发容易带来隐私问题”。

记者走访调查发现,网上流传着不少被称为“多开微信”“功能增强版微信”的外挂软件,付费后就能解锁这些被禁止的、可以被用以犯罪的功能。一些销售此类软件的卖家坚称这些外挂软件只是提供便利,至于用户买去做什么,“不是我们能负责的”。但记者从法律界人士处获悉,制造和销售这样的软件已经涉嫌违法甚至犯罪。

骗子用软件盗取微信朋友声音

“声音就是微信好友真实的声音。以现有技术不可能模拟出那么多朋友的真实语音。”记者从一些专业人士处获悉,微信语音是以AMR格式的音频文件储存在手机文件夹中,骗子应该是从某种渠道获取了这些声音文件。

不同于文字、图片和视频,微信的语音长按之后不会出现“转发”这一功能。腾讯CEO马化腾曾公开表示:“语音转发容易带来隐私问题,毕竟真人录音和文字、图片的情况很不同。”

“这样的设计并非不能‘绕开’,但品质要大打折扣。”专业人士称,在微信中如果想转发他人的语音文件,可以先找到相应的语音AMR文件,用音频软件播放,在微信中用“按住说话”功能发送该音频,“但这样的效果很差,声音小,而且模糊,稍有经验的人就能意识到这样的语音有问题。”

那骗子是怎样发出清晰语音的呢?目前网上已出现的所谓“功能增强版微信”,能直接转发语音,“骗子可以直接转发一个人的微信语音给微信上的其他好友,作为自己身份的证明,再进行‘借款’等行骗操作。”据业内人士介绍,对微信研发团队来说,增加语音转发功能在技术上并没有难度,他们顾虑的应该是这一功能的潜在安全隐患。

不过,正规企业的“底线”却被不法者突破,多地公安部门已经证实了这一类“功能增强版微信”的存在。据一些市民和网友反映,这样的“功能增强版微信”软件在网友口中被称为“多开微信”,因能与官方微信在一个设备上并存、可同时登录多个微信账号而得名。
