In what could put smartphone users at a new privacy and security risk, text-messaging management services are now being misused for as little as Rs 1,160 (nearly $16) to covertly redirect text messages from users to hackers, giving cybercriminals access to two-factor codes/login SMSes.

The invisible cyber-attack on companies providing SMS redirection services is reportedly being carried out in connivance with workers at telecom companies, reports Motherboard. "The method of attack, which has not been previously reported or demonstrated in detail, has implications for cybercrime, where criminals often take over target`s phone numbers in order to harass them, drain their bank account, or otherwise tear through their digital lives," the report said late on Monday.
