Symantec has been constantly monitoring phishing sites hosted on compromised Indian websites. In 2011, our study detailed these compromised sites and we did a similar study of phishing sites in 2012.

From August 2012 to November 2012, 0.11% of all phishing sites were hosted on compromised Indian websites. Phishers continue to target Indian sites across many disciplines to host their phishing sites. These Indian sites were classified in various categories. The most targeted sites were information technology (14.40%), education (11.90%), product sales and services (9.80%), industrial and manufacturing (7.30%), and tourism, travels and transport (5.80%). The figures for secure websites such as government, telecommunication, and ISP were low and at the bottom of the list. This offers evidence that phishers opt to target more vulnerable websites.

Earlier today we published our initial findings about the attacks on South Korean banks and local broadcasting organizations. We have now discovered an additional component used in this attack that is capable of wiping Linux machines.

The dropper for Trojan.Jokra contains a module for wiping remote Linux machines. We do not normally see components that work on multiple operating systems, so it is interesting to discover that the attackers...

Today, the Laboratory of Cryptography and System Security (Crysys) at Budapest University of Technology and Economics, released their research ­around a targeted attack they have identified, named TeamSpy. Symantec has had protections in place for this threat since 2011, and we currently detect this threat as Backdoor.Teambot. We also have the following IPS protections in place:

  • System Infected: Backdoor.Teambot Activity
  • System Infected: Backdoor.Teambot Activity2

This attack abuses the popular TeamViewer remote administration tool to control the malware running on victim machines. The Trojan packages the legitimate application along with a malicious DLL and uses an encrypted configuration file containing parameters to...

It has been reported in the media that several South Korean banks and local broadcasting organizations have been impacted by a cyber attack.

The attack included the defacement of a Korean ISP/telecoms provider and also the crippling of servers belonging to a number of organizations.

The defacement displays an elaborate animated Web page with sound effects, showing three skulls and included a message by the claimed attackers calling themselves the “Whois” team.

The attack was first noticed when a number of websites began to experience problems. Customers of banks could not access their online accounts and reports of other sites being down began to surface. While specific details are not known at this time, it has been reported that a number of sites affected had their hard drives wiped leaving the affected computers in a crippled state.

In recent days, the European Union (EU) financial crisis has taken a dramatic turn. Cyprus, one of the EU's smallest member states by population, announced plans to impose a one-off levy of up to 10 percent on ordinary bank deposits. Banks across the island state have been closed while the unprecedented measures are debated in the country's parliament. Meanwhile, anxious bank account holders—ordinary people, not bond holders or investors in Cypriot banks—await news of what will happen to their savings.

The notorious Blackhole Exploit Kit, previously featured in several posts on this blog, has started exploiting the public concern about this situation by sending out emails claiming to be news stories related to the unfolding situation.

Yesterday, Facebook users may have noticed an influx of their friends posting about something called Facebook Black.

Similar to previous scams, users are tagged in a picture that contains a link to an external website. In this case, the link is found within the comments instead of the description field (Figure 1).

The Vatican City has been in the news a lot in the past few weeks due to Benedict XVI’s resignation and the election of Pope Francis. Spammers have picked up on this opportunity for spreading malware.

Symantec Security Response has observed attackers distributing spam which leads users to a site hosting the Blackhole Exploit Kit. The good news is, Symantec customers are protected and this threat is detected as Blackhole Toolkit Website.

The spam email alleges to be from a well-known news channel. The following subject lines are used in this attack:

  • Subject: Opinion: Can New-Pope Benedict be Sued for the Sex Abuse Cases? - [REMOVED]
  • Subject: Opinion: New Pope, Vatican officials sued over alleged sexual abuse! - [REMOVED]
  • Subject: Opinion: New...

Earlier today, we blogged about Android.Uracto, a malicious app that sends spam SMS messages in an attempt to infect others or scam users into paying a fee for a non-existing service. We continued doing further investigation on the attack and this has led us to discover more apps prepared by the same group of scammers. So far we have been able to find a total of 10 apps hosted on a few dedicated domains believed to be maintained by the group. The servers hosting the domains appear to be located in Singapore and in Georgia in the United States. They are currently still live at the time of this writing.

SMS messages attempting to lure Android device owners to download an app that supposedly allows the camera on the device to see through clothes are circulating in Japan. This type of spam is usually sent by the malware authors themselves, but in this case the authors have developed an app to send the spam messages by SMS to phone numbers stored in the device’s Contacts. This allows the recipients of the spam to be tricked easier because the invitation to download the app is coming from someone they know rather than from an unknown sender. If a friend is recommending an app, why would you not at least try it out, right?

The Cheltenham Festival, also known as the National Hunt Meeting, is a popular horse racing event that occurs every year in March in the United Kingdom. The festival usually coincides with Saint Patrick's Day. This year, the festival is currently in progress and will end on March 15. A large amount of gambling takes place during the Cheltenham Festival, a fact that spammers seem to be well aware of as we are presently observing an increase in online gambling spam.

One particular sample of spam included instructions on how to register a free bet. The link provided in the message directs the user to a form where they can sign up and get a free bet worth up to £50.

Some of the email header information found in this spam campaign includes the following:

  • Subject: Bet on Cheltenham with the Best Odds!
  • From...
