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?

St. Patrick’s Day is a global celebration of Irish culture and a religious holiday on March 17, and it is very special to Irish communities and organizations. Recently, we have observed numerous St. Patrick’s Day related spam messages flowing into the Symantec Probe Network. Many of the spam samples observed are encouraging users to take advantage of clearance sales of cars as well as other product offers.

Interestingly, in one spam campaign, we observed a malicious spam email that tries to trick users by using the name of the event in conjunction with a popular site that allows users to send and receive large files. By clicking on the link, the user is redirected to a Web page that downloads some malicious code, which exploits several common vulnerabilities. The main motive of these spam campaigns is to lure recipients by taking advantage of the St. Patrick’s day holiday in the subject line and body of the email, such as: “Patrick[RANDOM NUMBERS]...

Rumors of Venezuelan President Hugo Chavez’s death were rampant on the news and Internet over the past month, and last Tuesday, the Venezuelan Vice President confirmed that Chavez died after a two year battle with cancer. Chavez’s death has triggered reactions worldwide, from world leaders to ordinary citizens, and everyone is talking about his ideas and actions as Venezuelan President. At the same speed as the news is spreading, cybercriminals are using this opportunity to send malicious links related to his death as well as hypothetical theories about the cause of his sickness and death.

All the links that we have seen contain malware. Some domains have been registered recently and others seem to have been hijacked.

Here is an example email used in these attacks:

Symantec recently received information on a new Java zero-day, Oracle Java Runtime Environment CVE-2013-1493 Remote Code Execution Vulnerability (CVE-2013-1493).  The final payload in the attack consisted of a DLL file, detected by Symantec as Trojan.Naid, which connects to a command-and-control (C&C) server at 110.173.55.187. 

Interestingly, a Trojan.Naid sample was also signed by the compromised Bit9 certificate discussed in the Bit9 security incident update and used in an attack on another party.  This sample also used the backchannel communication server IP address 110.173.55.187.   

The Trojan.Naid attackers have been extremely persistent and have shown their sophistication in multiple attacks.   Their...
