Chinese students studying in the UK have been one of the most common targets of scammers. RedZei (aka RedThief) Group, a Chinese-speaking scammer group that operates online and is becoming more common these days, bypasses all the precautions that users and service providers have taken to prevent scams.
This is how it works
Chinese students were fooled into paying millions of dollars to avoid deportation as part of a visa scam, according to a report in The Guardian. According to researchers, this incident is likely to be the result of the RedZei campaign that began in August of last year.
Redzepi fraudsters carefully selected their victims by researching them, they also sought out a potential victim who was wealthy enough to be a profitable target. Fraudsters would use new pay-as-you-go U.K. phone numbers for each wave of the attack to bypass the phone number-based blocking on each wave. There are several mobile carriers used by the attackers, such as Telia, Three, EE, O2, and Tesco Mobile, with which they move between SIM cards.
