Crime Advisory – Resurgence of scams involving takeover of Whatsapp accounts

Redirected from Singapore Police Force

The Police would like to alert on a resurgence of scams involving the takeover of WhatsApp accounts.

In such a scam, a victim would receive a WhatsApp message from a friend, whose WhatsApp account has been compromised, requesting the victim to send over a 6-digit verification code sent to them. The victim would thereafter lose access to his or her WhatsApp account after providing the scammers with the 6-digit verification code.

Members of the public are advised to adopt the following crime prevention measures:

a) Do not share your account verification codes with anyone;

b) Beware of unusual requests received over WhatsApp, even if they were sent by your WhatsApp contacts;

c) Always call your friend to verify the authenticity of the request, but do not do so through the social media platform as the account might have been taken over by scammers; and

d) Protect your WhatsApp account by enabling the ‘Two-Step Verification’ feature, which is available under ‘Account’ in the ‘Settings’ tab of your WhatsApp application. This will prevent others from compromising your WhatsApp account;

e) In the event that your WhatsApp account has been taken over by a scammer, you can recover the account by signing into your WhatsApp using your phone number and authenticate by entering the verification PIN which you will receive on your phone. The scammer which is using your account will automatically be logged out thereafter.

If you wish to provide any information related to such scams, please call the Police hotline at 1800-255-0000, or submit it online at www.police.gov.sg/iwitness. If you require urgent Police assistance, please dial ‘999’.

Together, we can help stop scams and prevent our loved ones from becoming the next victim.

两新伎俩盗取WhatsApp账号 警方提醒公众切勿分享验证码

来自 / 联合早报 发布 / 2021年1月11日 3:30 AM

盗取WhatsApp账号最近出现两种新手法,警方提醒公众不要落入陷阱,别跟他人分享验证码。

警方发文告说,第一种手段是受害者会收到冒充WhatsApp技术支援员工的信息,称接获有关受害者的投诉,受害者须提供发送到手机的六位数验证码加以确认。受害者一旦提供那组号码,就会失去WhatsApp账号的权限。

WhatsApp已声明不会请用户分享验证码。

另一种是诈骗者故意不断将错误的验证码输入它的仪器。验证码多次输入失败,WhatsApp会要求用户进行“声音验证”,通过发送含有六位数验证码的录音信息给受害者。

如果受害者不加理会或没打开手机,录音信息会直接转入受害者的留话信箱(Voicemail)。

电信服务公司会发送默认密码(default pin)给用户,骗子就利用默认密码远程侵入留话信箱,然后取得录音信息的验证码。

一旦得到验证码,骗子可掌控WhatsApp账号,然后启动“两步验证”(two-step verification)功能,阻止受害者取回账号权限。

另外,警方指骗子还沿用过去的招数,利用所盗取WhatsApp账号的受害者身份,向受害者的亲友下手。

骗子要受害者亲友提供发到他们手机的一组六位数密码,受害者的亲友一旦回复提供密码,手机也会中招,跟着失去WhatsApp账号权限。

警方再度提醒别与人共享WhatsApp账户验证码,即使相关要求来自存在手机里的联络人。

手机用户可启动“两步验证”功能,或更改留话信箱的默认密码。如果没使用留话信箱,就联络电信公司终止相关功能。
