Australia continues to rank as one of the top ten countries worldwide to suffer online brand attacks, and while Colombia and France have dropped off the chart completely, New Zealand and Brazil have entered the list for the first time, according to a new report on worldwide fraud released today.
According to RSA’s online fraud report for
October, despite the rise in the total number of brand attacks launched
in September, and an increase in the number of brands targeted last
month, phishers generally continue to attack brands in the same
countries, namely Australia, the US, the UK, Canada, Italy, Spain and
South Africa.
Also reported by RSA was the fact that financial institutions in
Australia, Asia and Latin America are increasingly deploying two-factor
authentication for their online banking users and, as a result, have
experienced an increasing number of ‘man-in-the-browser’ (MITB) attacks.
RSA reports that it has witnessed a surge in the number of MITB
attacks, “especially in geographies where two-factor authentication is
densely deployed --- such as the European consumer banking and US
corporate banking markets.”
The security firm says a man-in-the-browser attack is designed to
intercept and manipulate data as it passes over a secure communication
between a user and an online application, and that a Trojan embeds in a
user’s browser application and can be programmed to trigger when a user
accesses specific online sites, such as an online banking site.
According to RSA, a number of Trojan families are currently being used
by fraudsters to conduct MITB attacks including Zeus, Adrenaline,
Sinowal, and Silent Banker, and it says some MITB Trojans are so
advanced that they have “streamlined the process for committing fraud,
programmed with functionality to fully automate the process from
infection to cashout.”
RSA warns that what makes MITB attacks difficult to detect from the
bank’s server side is that any activity performed “seems as though it
is originating from the legitimate user’s web browser.”
“Characteristics such as the Windows language, user agent string, and
the IP address will appear the same as the user’s real data. This
creates a challenge in distinguishing between genuine and malicious
transactions.”
RSA also says that man-in-the-browser as an attack vector has
experienced exponential growth in the rate of infection in the last
year, and it has witnessed Trojan infections increase tenfold in the
last twelve months – findings which it says that are supported by other
industry observations and reports.
“This growth is driven in part by the number of ‘drive by download’
infections where vulnerabilities on legitimate websites are exploited
by botnets and infection kits to place an iFrame in the breached site,”
RSA says.
