- Phishing attacks now bypass multi-factor authentication using digital portfolio provisioning in real time
- Unique passing codes are no longer enough to stop fraudsters with optimized mobile phishing kits
- Millions of victims have been targeted using daily alerts such as tolls, packages and account opinions
A wave of advanced phishing campaigns, established in Chinese-language cybercriminal unions, may have compromised up to 115 million American payment cards in just over a year, experts warned.
The researchers of Secalliance have revealed that these operations represent an increasing convergence of social engineering, realization by real time and phishing infrastructure designed to evolve.
Investigators identified a figure called “Lao Wang” as the original creator of a largely adopted platform which facilitates the mobile identification harvest.
Identity flight on scale by mobile compromise
At the center of the campaigns are phishing kits distributed by a telegram channel known as “Dy-Tongbu”, which quickly gained ground among the attackers.
These kits are designed to avoid detection by researchers and platforms, using geofencing, IP blocks and targeting of mobile devices.
This level of technical control allows phishing pages to reach the expected targets while actively excluding traffic which could point out the operation.
Phishing attacks generally start with SMS, iMessage or RCS messages using daily scenarios, such as toll payment alerts or package delivery updates, to drive the victims to false verification pages.
There, users are invited to enter sensitive personal information, followed by payment card data.
The sites are often optimized by mobile to align with devices which will receive punctual password (OTP) codes, allowing an immediate multi-factor authentication bypass.
This identification information is provisioned in digital portfolios on attackers controlled by attackers, allowing them to bypass the additional verification steps normally required for Non-Print card transactions.
The researchers described this passage to the abuse of digital portfolio as a “fundamental” change in the methodology of card fraud.
It allows unauthorized use in physical terminals, online stores and even automatic ticket distributors without requiring the physical card.
Researchers have observed criminal networks now going beyond Smirs campaigns.
There are more and more false electronic commerce sites and even false brokerage platforms used to collect identification information from users without distrust engaged in real transactions.
The operation has developed to include layers of monetization, including preloaded devices, false merchant accounts and advertisements paid on platforms like Google and Meta.
While card issuers and banks are looking for ways to defend themselves against these evolving threats, standard security consequences, firewall protection and SMS filters can offer limited aid given the precision targeting involved.
Given the secret nature of these Smirs campaigns, there is no single public database listing the assigned cards. However, individuals can take the following measures to assess possible exposure:
- Review recent transactions
- Look for an unexpected digital portfolio activity
- Monitor for verification or OTP requests that you have not initiated
- Check if your data appears in the violation notification services
- Activate transaction alerts
Unfortunately, millions of users may remain ignorant that their data has been used for large -scale identity theft and financial fraud, facilitated by traditional offenses.
