Spring epidemics in Skype: watch out for Bitcoin fraudsters


Mo
skau,

.
April
2013



Kaspersky Lab experts have detected two malicious
campaigns operating on Skype: in both cases cybercriminals are using social
engineering methods to lure users to foll
ow a malicious link with the promise of
an interesting photo or video. Hacked or specially created Skype accounts are
used to distribute the malicious links in both campaigns


one of which aims to
fraudulently generate the Bitcoin virtual currency.


The

first attack was launched as early as March 1, but over the past 24 hours users
clicked the malicious link an average of 2.7 times per second, or 10,000 times per hour.
Those clicking the links are primarily in Russia, Ukraine, Bulgaria, China, Taiwan and

Italy. When analyzing the code loaded to the victim’s PC, the company’s experts found
a line that mentioned ‘Bitcoin wallet’.


On Thursday, April 4 another similar attack was detected. Users were asked to follow a
link, but the experts at Kaspersky Lab f
ound that malware capable of generating the
Bitcoin currency was being installed on computers. The Bitcoin currency system allows
users to earn bitcoins in return for leasing out their computing resources. The virtual
money can later be converted into anot
her currency or used to pay for goods and
services in online stores. Although the latest malicious campaign was only launched
one day ago, it has rapidly gained momentum. By Thursday evening around 2,000
users were following the malicious link every hour,

according to calculations by Dmitry
Bestuzhev, Head of the Latin American Global Research & Analysis Team at Kaspersky
Lab.


The geographical distribution of the attack suggests users in Italy, Russia, Poland,
Costa Rica, Spain, Germany and Ukraine are t
he main targets of this second malicious
campaign.


It seems unlikely to be a coincidence that the malicious campaign began when the
Bitcoin exchange rate hit its historical peak. On April 5, the rate reached $132 per coin

a dramatic growth compared to t
he 2011 rate of below $2 per coin. This is too tempting
for cybercriminals to ignore, says Kaspersky Lab expert Sergey Lozhkin.


“Of course cybercriminals couldn’t help but pay attention to Bitcoin. The Bitcoin
currency transactions system itself implies f
ull anonymity and that’s why cybercriminals
started using it so actively. Underground forums are full of offers to buy and sell with
Bitcoins. Drugs, arms, 0
-
day exploits, Trojans and viruses are bought and sold using
the currency,” said Lozhkin. “Anonymo
us transactions are very hard to track and with
so many currency exchange services
-

both legal and underground
-

it’s easy to lose
track of the details with nobody any the wiser. This makes cybercriminals feel very safe.
The Bitcoin architecture implies t
hat more of them exists more hardware resources
needed to mine. That’s why we are seeing malware that installs a Bitcoin miner module
on victim computers, using their resources to mine Bitcoins and create a Bitcoin
-
mining
botnet that could be quite a good
source of income for its owner.”


Kaspersky Lab recommends that Skype users treat any messages arriving via Skype or
any other Instant Messaging program with caution. Even if a message arrives from a
person you know, it is possible that his/her computer ha
s been infected and is
controlled by cybercriminals. We also advise users to do the following to ensure their
device stays secure:



Install and maintain an up
-
to
-
date advanced Internet Security solution



Keep the operating system up to date



Update all third
-
party applications



Use a secure browser to access the Internet



Practice safe computing. Use strong passwords that contain letters, numbers
and symbols (?#!., etc…). Make sure you use a different password for each websit
e or
resource.



Use your common sense.



Kaspersky Lab’s products detect the malicious programs used in both attacks.
