Scammers targeting customers of mobile carrier O2 are enticing victim engagement by offering discounts on their mobile plan as much as 40%.
ZDNet contributor, Charlie Osborne, told of their personal experience with this scam in which they were the recipient of a cold-call scam from someone claiming to be with O2. In this scam, the caller sounds happy to inform the victim they have been selected to receive a 35% to 40% discount on their phone service.
As part of the scam, the caller accesses the O2 customer page and enters in the victim’s mobile number. When prompted for the one-time security code send via text to the victim, the scammer asks for the code in order to “apply the discount”.
