Mother’s Day is celebrated in many countries on May 12 and it’s a day for children, regardless of age, to express their love to their mother by giving her a gift. Spam messages related to Mother’s Day have begun flowing into the Symantec Probe Network. Clicking the URL contained in the spam message automatically redirects the recipient to a website containing a bogus Mother’s Day offer upon completion of a fake survey.

Once the survey is completed, a page is then displayed asking the user to enter their personal information in order to receive the bogus offer.

Microsoft has issued Security Advisory 2847140 in response to reports regarding public exploitation of a vulnerability affecting Internet Explorer 8. Other versions such as Internet Explorer 6, Internet Explorer 7, Internet Explorer 9, and Internet Explorer 10 are not affected. Initial reports indicate that a website associated with a department of the US government was compromised to host the exploit in what’s known as a watering hole attack. Upon visiting the site a vulnerable victim would have been redirected to download a back door as the payload.  Symantec products detect the exploit code on the vulnerable site as Trojan.Malscript, Bloodhound.Exploit.494, or...

If you haven’t heard, Google Glass, the latest gadget from the Silicon Valley giant, has set the media and tech world abuzz, with both admiration and controversy surrounding the device. Google Glass was released to the public last week and combines smartphone technology with wearable glasses that is reminiscent of something seen on Star Trek. Public, in this case, actually means beta testers (called Glass Explorers) who had to apply for the chance to purchase the spectacles in advance by writing a 50 word essay using the hashtag, #ifihadglass. Those chosen had the opportunity to purchase the device for $1,500 USD.

Along with the admiration of a device that appears to do everything, comes controversy.  The 8,000 individuals who were able to purchase the device were bound to a restrictive end user license agreement, in which the product would be deactivated and rendered...

Last week, Symantec posted a blog on an increase in spam messages with .pw URLs. Since then, spam messages with .pw URLs have begun showing up even more.

Symantec conducted some analysis into where these attacks are coming from in terms of IP spaces. As expected, Symantec observed a large quantity of mail being sent from an IP range and then moving to another IP range. While this is an expected behavior, there was an interesting twist. There were multiple companies (with different names) hosting .pw spammers using the same physical address in Nevada. 

Examining messages found in the Global Intelligence Network, Symantec...

For that past several days, Symantec has observed an increase in spam messages containing hexadecimal obfuscated URLs. Hexadecimal character codes are simply the hexadecimal number to letter representation for the ASCII character set. To a computer, hexadecimal is just one out of the many systems for address expressions on the Internet.

The following samples are different hexadecimal representations for http://www.symantec.com.

Hexadecimal only:

http://www.

Hexadecimal and ASCII characters:

In today’s connected world, many of us are members of at least one, if not more, social networking services. The influence and reach of social media enterprises, such as Facebook (more than 600M active users per month) and Twitter (more than 140M active users), is staggering and as communications tools they offer a global reach delivering almost instantaneous communications to huge multinational audiences. Social media is attractive for hacktivists because it is a forum for people on the Internet and where big discussions take place. Hijack a forum like this and you have an effective soapbox to get your message across. Hardly a day passes without news of another high profile breach by hacktivists and social media influencers are in the crosshairs. Are...

Nearly every week now we can read about a data breach case somewhere, where millions of user accounts and potential other sensitive data has been compromised. Most people are not even shocked by such news anymore, as it is starting to become humdrum.

One of the most common attacks used in such breaches is an SQL injection. This attack has ranked first place on OWASPs Top 10 faults in Web applications for many years. There are several well-known methods to prevent SQL injections, but unfortunately it is still often encountered in productive sites. Furthermore, mis-configured Web servers and vulnerabilities in remote management tools can allow attackers to gain access to systems and read potentially sensitive files.

There has long been a heated discussion about how best to store passwords and that discussion is still ongoing. Most people agree that storing passwords in clear text in a database...

Phishers have recently gained a lot of interest in football. Various phishing attacks using football were observed in 2012. Phishers have already shown their interest in the 2014 FIFA World Cup, football celebrities, and football clubs. Scam for LIONEL MESSI Fans and Scam for FC Barcelona are good examples of phishers using football celebrities and football clubs. Fraudsters understand that choosing celebrities with a huge fan base offers the largest amount of targets which could increase their chances of harvesting user credentials. In April 2013, the trend continued with phishers using the same strategy. The phishing sites were in French on a free web hosting site.

The phishing sites prompted users to enter their Facebook login credentials on pages designed to...

Symantec has observed an increase in spam messages containing .pw top-level domain (TLD) URLs.  While it was originally a country code top-level domain for Palau, it is now available to the general public through Directi, who branded it as “Professional Web”.

Looking back at the last 90 days, .pw ranked #16 on our TLD distribution list:

Join Symantec Security Response experts Kevin Haley and Paul Wood on Twitter (using the #ISTR hashtag) on Tuesday, April 30, at 9 a.m. PT / 12 p.m. ET to chat about the key trends highlighted in Symantec’s recently released Internet Security Threat Report (ISTR), Volume 18.

The ISTR, which covers the major threat trends observed by Symantec in 2012, reveals a significant increase in cyberespionage attempting to gain access to confidential information and valuable intellectual property, and shows how criminal methods of obtaining this information are shifting. In fact, the largest growth area for targeted attacks in 2012 was businesses with fewer than 250 employees; 31 percent of all attacks targeted them, representing a threefold increase from 2011.

Mark your calendars to join the #ISTR chat and plan to discuss the latest attack vectors and techniques used by...
