A new industry for would-be internet
fraudsters is emerging, helping those without technical knowledge or
resources to advance their cybercrime careers, Uri Rivner, RSA's Head
of New Technology told delegates.
Facilities such as professionally run
discussion forums that often include in-depth reviews of malware
products and money laundering services are just some of the new
sources of help for fraudsters, he said.
In practice, this means that online
fraud is now a serious option for many who would previously have
suffered from their lack of technical know-how. “We estimate that
only about 10% of online fraudsters have the technical knowledge
needed to securely host and regularly upgrade malware, and infect a
large number of computers with it,” he said.
The market for malware products and
services mirrors the legitimate software industry, with competition
between malware developers forcing prices down, and spawning
innovative new service models, said Rivner.
The Limbo trojan is a good example of
the new breed of “affordable” and carefully designed malware
products, offered at $350, he said. When present on a victim's PC,
Limbo can insert code into the HTML received from banking websites,
appearing on the screen as extra fields that typically request
important account details. The page itself is genuine and the fields
are seamlessly inserted, said Rivner.
Fraudsters can also receive help in
placing malware on machines in the first place, with infection
services priced per thousand machines, said Rivner. Prices also vary
according to the target country, and whether exclusive or
non-exclusive infection is offered. These developments are paving the
way for the concept of “fraud as a service,” said Rivner.
However these sophisticated new models
have their own vulnerabilities. Online forums where products are
offered for sale and business deals are discussed are also
communication bottlenecks. Gaining a reputation is an important part
of acquiring customers, and fraudsters may unwittingly reveal
important clues about their true identity, said Rivner.
