June 2, 2020 – dtac warns its customers to stay vigilant against phishing scams, offering services from dtac and asking for password required for transactional banking. According to the recent news about a pharmacist who received a call from a scammer, claiming to be a mobile operator and informing her that there was a duplication in her phone number. The scammer offered to fix this problem and the victim believed, which led to sharing OTP (One-time Password) used to provide security in online transactions. The victim’s OTP was later used for e-banking, transferring money to the scammer’s account as reported in the news.
Due to the recent incident and other possible scams, dtac urges customers and the public to be watchful for this kind of contact and be careful in all channels risking online scams. dtac confirms that the company has no policy in asking for an OTP sent to a customer’s device. dtac employees only contact customers through the official dtac channels: Call Center 1678, Facebook dtac, and Twitter @dtac.
During the COVID-19 pandemic, dtac has urged customers to be vigilant through all forms of communication, including press releases, Facebook, LINE, and Twitter and has made sure that this message is delivered to all customer groups. Communicating about this issue has a high priority these days because customers have shifted their behavior to more online transactions.
All mobile users must keep in mind that an OTP is a very important piece of information. It’s a one-time password designed to provide security in online transactions. The OTP is sent via SMS, e-mail, or application to allow the authentication of each user. The password is valid within a short period of time and will no longer be valid after that or after using. Scammers can use this one-time password for authentication. Therefore, sharing OTP isn’t recommended in all cases because this is a key for scammers to commit many types of fraud.
