Crime without punishment: in-depth analysis of JS-sniffers
JS-sniffers pose a growing threat by attacking online stores and stealing payment data and credentials of their users. Group-IB experts have researched this type of malware and have discovered at least 38 families of JS-sniffers, whereas only 12 were known previously.

Key facts
Group-IB experts have discovered 38 different JS-sniffer families, whereas only 12 were known previously
The total daily number of visitors of all the infected sites exceeds 1.5 million people
By selling compromised payment data cybercriminals can earn from $1 to $5 per card
JS-sniffers can be bought or rented on underground forums, with their price ranging from $250 to $5,000
This class of malware seemed to be a rather primitive threat to large players like banks and payment systems, since JS-sniffers were believed to target small online stores. Now, however, it is time to question that belief. When a site is infected, everyone is involved in the chain of victims — end users, payment systems, banks that issued compromised cards, and companies that sell their goods and services online.
The urgency of the problem is linked to its potentially huge audience (today, almost all of us use online stores). Group-IB Threat Intelligence & Attribution specialists continuously monitor the appearance of new JS-sniffers and appeal to the cybersecurity community to take a closer look at this growing threat.
