Owners of 1-Time Passcode Theft Service Plead Guilty

Three men in the UK have pleaded guilty to operating OTP Agency, an online service that facilitated the theft of one-time passcodes (OTPs) used for two-factor authentication. Launched in November 2019, the service allowed scammers to intercept OTPs by tricking victims into providing their codes through automated phone calls. The National Crime Agency (NCA) reported that the service targeted over 12,500 individuals during its 18-month operation. The guilty parties include Callum Picari, the main operator, along with Vijayasidhurshan Vijayanathan and Aza Siddeeque. Following a February 2021 article that exposed their activities, the operators attempted to shut down the service but quickly resumed operations under a new Telegram channel. The NCA began investigating OTP Agency in June 2020, leading to the arrests of the trio. Despite the closure of OTP Agency, similar services continue to operate, posing ongoing risks to online security. The NCA advises individuals to be cautious of unsolicited calls regarding potential fraud and to verify account statuses directly with their financial institutions.

As the other comment said, they should go after all their customers too. I can't believe they are thefts out there paying other thefts for theft-services...

Unrelated, but at the start of the year, a lot of Payoneer customers from Argentina lost their savings in the platform* due to someone having access to the OTP codes. Payoneer said it wasn't on their side the error, and evidence suggested that it was an error in Movistar, because all the victims were customers of that particular telco. As far as I know, Payoneer didn't return the money and Movistar was never charged or anything (rumours say it was a Movistar employee who sold SMS with the OTP).

And if you ask why a lot of Argentina people use Payoneer and keep their savings there, it's a bit long to explain but basically is their way to get paid in USD outside the country without paying taxes (fair and unfair ones) and without getting their payments converted automatically to ARS pesos using a bad rate.

Schools really need to teach kids not to trust the identity of anyone who initiates contact them unless they can physically see them in person and already know them personally. If the general population had this skill ingrained in them, all phishing scams would poof away into uselessness.

I am trying to think on how this could be mitigated and I am not sure there is a good way. Just before we even begin, using an unknown third party is a risk and companies have no problem using whatever providers. Just dropping OTP is not exactly ideal either so we are stuck between rock and a hard place.

I think the guy who stole my phone used one of these services, a couple of days later I received a notification with a temp code and then a url where to enter it, as I had to confirm that the phone was mine since it was found

Why does the blog post show their photographs? That seems unnecessary to me.
