Over the weekend, a large number of Pinterest accounts were compromised and used to pin links to a miracle diet pill spam called Garcinia Cambogia Extract. Since most of the compromised accounts were linked to Twitter, these spam “pins” on Pinterest were also cross-posted to Twitter.

Back in April, we published a blog on compromised Twitter accounts used to promote the same miracle diet pill spam. During our investigation, we made a connection to the Pinterest hack reported by TechCrunch in late March.

In March 2014, the Zorenium bot (W32.Zorenium) made headlines after the malware’s author claimed that the information-stealing threat had been updated with some advanced new features. According to the malware author, known as Rex, these features included the ability to run on iOS and Android devices, steal banking credentials, support peer-to-peer (P2P) communications, and spread over Skype and Facebook.

The malware originally appeared in 2013 and Symantec has observed how it has evolved over time. If Rex’ claims were true, then the update could have made Zorenium a major threat. While this update’s full feature set was never proven, Rex stood by the iOS claim and later stated that the iOS code came from a third party. In this...

Last week, Apple introduced the new version of its mobile operating system, iOS 8, at its Worldwide Developers Conference. Apple unveiled many new features for iOS 8 in different categories and some of them were security related. Now that iOS 8’s new features have been revealed, it’s time to take a look at the possible security implications surrounding these enhancements. 

Since iOS 8 has not yet been released, it is unclear how exactly these features will be implemented. Based on the information currently available, there is a handful of security features that should enhance iOS devices’ protection levels.

iOS app extensions – More than just third-party keyboards
One of iOS 8’s most discussed enhancements is its app extensions, which will allow third-party apps to communicate with each other. With app extensions,...

It’s well known that hot political topics make enticing lures for cyberattacks and, as such, Symantec is constantly on the lookout for attacks using this tactic. Recent monitoring of the global political landscape led us to observe a malicious campaign piggybacking on the coup d’état that occurred in Thailand three weeks ago (May 19, 2014) after months of turmoil in the country. We have seen the emergence of a limited and targeted spam campaign against government officials in Southeast Asia

The malicious emails claim to be from a well-known media institution based in Myanmar and come in three variations where only the attached Word document’s name changes:

  • The_Military_situation_in_Thailand.doc
  • Thai_Coup_Leader_Says_He_Has_Received_King.doc

With the 2014 FIFA World Cup in Brazil just around the corner, scammers have kicked off efforts to target fans of the international football event. World Cup fans everywhere should watch out for free ticket scams, news service scams, and online streaming scams. Symantec has already identified several email scams and we expect to see attempts to target fans on social networks.

Free tickets to the World Cup

The most common scam around the World Cup involves free tickets. After all, what fan would not want an all-expenses paid trip to Brazil? Scammers know a dream come true is hard to pass up and circulate emails promising everything imaginable.

Just around this time last year, Symantec came across a fake security app called Android Defender (Android.Fakedefender) that held mobile devices hostage until a ransom was paid up. This particular malware locked up the device, making it useless, in order to coerce the user into paying for the app. Now, a year later, a batch of malicious apps that take files stored on mobile devices hostage by encrypting them have been discovered in the wild by security researchers. These variants, which Symantec detects as Android.Simplocker, pretend to be legitimate apps and appear to be hosted on fake Google Play sites aimed at Russian-speaking Android device owners. An example of one of these fake sites can be seen in Figure...

Figure. List of the latest patched OpenSSL vulnerabilities

The OpenSSL project recently released patches for several OpenSSL vulnerabilities, two of which are marked as critical. One of the critical vulnerabilities, OpenSSL CVE-2014-0224 Man in the Middle Security Bypass Vulnerability (CVE-2014-0224), could let an attacker carry out a man-in-the-middle attack, allowing them to intercept traffic between a vulnerable client and a vulnerable server. One way that attackers could exploit this flaw is by setting up a rogue Wi-Fi hotspot in a public area. If a user connects to this rogue access point, the attackers controlling...

Dating back to last year, Symantec has been following a trend involving adult webcam spam on social networks, dating applications, and photo sharing applications. Our research found that no matter which platform it was found on, most adult webcam spam shared a common thread: it led users to a mobile messaging service called Kik.

What is Kik?
Kik is an instant messaging service available for all smartphone platforms. The service has more than 100 million users and is extremely popular with teenagers.

A recent history of adult webcam spam

Twitter
The first cross advertising for Kik spam made its way to Twitter towards the end of summer 2013. Spam bots would target specific keywords and send a reply when one was found. For instance, tweets with the word “horny” would be met with a response from a spam bot, posing as a female, containing the word “horny.” The message would ask the user to reply back...

Everyone hates getting bills, and with each new one it seems like the amount due just keeps getting higher and higher. However, Symantec recently discovered an energy bill currently being emailed to people that will hit more than just your bank account.

A recent spam campaign sending out emails masquerading as an Australian energy company is serving up the Cryptolocker malware…or at least that’s what the spammers want you to think. Once users become infected, they are told they are infected with Cryptolocker (Trojan.Cryptolocker) however, upon further research, Symantec discovered that the malware is not related to the original Cryptolocker virus and is merely a copycat attempting to cash in on the hype and infamy of Cryptolocker.

Energy bill gives users a shock
This particular spam campaign requires a lot of work from the victim to work but once it...
