If you’re in the market for a new mobile phone plan, it’s best to avoid turning to Boom! Mobile. That is, unless you don’t mind your sensitive payment card data being sent to criminals in an attack that remained ongoing in the last few hours.
According to researchers from security firm Malwarebytes, Boom! Mobile’s boom.us website is infected with a malicious script that skims payment card data and sends it to a server under the control of a criminal group researchers have dubbed Fullz House. The malicious script is called by a single line that comprises mostly nonsense characters when viewed with the human eye.
