As the urban legend goes, the bank robber Willie Sutton was asked why he robbed banks. “Because that’s where the money is,” he is attributed as saying. While Sutton has long since distanced himself from the statement, the concept resonates with many people, to the extent that it’s been used to describe principles in accounting and even medicine.  

This principle also holds true in the world of Internet security. In the latest version of the Internet Security Threat Report we discussed the major trends in the spam world, where the percent of spam email continues to decline while more and more social networks are being targeted. Given the growth of social networking in recent years as a means to communicate, this...

Since the beginning of the year, a Japanese one-click fraud campaign has continued to wreak havoc on Google Play. The scammers have published approximately 700 apps in total since the end of January. The apps are published on a daily basis and the scammers have invested around US$4,000 in order to pay the US$25 developer fee to publish apps on Google Play.

Dealing with the fraudulent apps has really become a game of cat and mouse. Once the apps are removed from Google Play, the scammers simply publish more under new developer accounts. These are again removed shortly afterwards, but the scammers simply continue to publish more. Most of the apps are removed on the date of publication,...

Celebrity scandals are always popular and phishers are keen on incorporating them into their phishing sites. Recently, we observed a phishing site featuring British singer and actress Rita Ora. The phishing site was hosted on a free Web hosting site.

The phishing site prompted for Facebook login credentials that called the video a “social plugin”. The phishing page contained an image of a fake YouTube video of Rita in the background. The title of the video in question described it as an adult video of Rita Ora. A recent event involving an accidental exposure of Rita instigated phishers into devising this bait. The phishing site gave the impression that users could view the video shown in the background when login credentials are entered. In reality, after login credentials are entered,...

In the last few weeks we have observed a drastic increase in “penny stock” spam emails. In 2011 Symantec published a blog entitled Global Debt Crises News Drives Pump-and-Dump Stock Scams, which also dealt with this type of spam.

Penny stocks, also known as cent stocks, are shares in small companies that trade at low prices, often as low as a few cents per share. Penny stocks are a very popular topic used by spammers. The spam emails advertise the cheap shares and state that the company is on the verge of becoming very successful and that the value of the shares will rise significantly. The emails make out that the company is more valuable than it actually is and implies that they have just created some major product or are on the verge of a breakthrough and that the share value is tipped to rise dramatically. The aim is to increase sales of the stock,...

In April 2013, Symantec was alerted to a series of sophisticated social-engineering attacks targeting a limited set of organizations in Europe. The most distinguishing feature of these attacks is that the victim will receive a phone call from the attacker who impersonates an employee or business associate of the organization. The caller spoke in French and asked the victim to process an invoice that they were to receive in an email.

Here is an example of an email that was received during one of the attacks. The email typically contains a malicious link or an attachment, which is actually a variant of W32.Shadesrat, a Remote Access Trojan (RAT).

In the last few months, we have witnessed a rise in the number of cases of modified Web servers that inject malicious redirections into every website that it hosts. One example was the malicious Apache module (Linux.Chapro and Trojan.Apmod) that we blogged about recently. A newer example is Linux.Cdorked, about which our friends at ESET also wrote.

With Linux.Cdorked, instead of adding a malicious Apache module to the configuration list, the attackers instead replaced the main httpd binary file...

The 58th season of the UEFA Champions League is coming to an end with the final being played on May 25 at Wembley Stadium in London. Nowadays, cybercriminals are gaining a lot of interest in football, at least inasmuch as how to exploit interest in football to their advantage, and Symantec has recently blogged about cybercriminals continuing to show interest in football.

Spammers are exploiting the latest sporting event by sending spam of fake ticket offers through email. Below is an Italian spam campaign we have observed targeting the UEFA Champions League with a fake ticket offer promotion.

The spam can be identified by the following headers:

People dream big when buying expensive items like a car or a property. When those dreams are seen with very affordable price tags it certainly attracts everybody’s interest. There are lots of websites available that allow people to post free classified advertisements online and one of the biggest categories is that of used cars. This is the new breeding ground for the old escrow tricksters.

This blog will discuss an interesting case of how a free classified advertisement and an escrow service turned out to be an online scam.
 

What are escrow services?

Escrow services are essentially mediators in trade that ensure all terms, agreed by both parties, are met. Escrow companies take the payment from the buyer and ‘hold it’ until the seller delivers the goods to the buyer and all the terms of sale are met. If you are buying an item from an unknown party without meeting face-...

Following on from recent concerted campaigns by Anonymous against Israel on April 7 and Facebook on April 5, the latest target for the online hacktivist collective is the USA and American online interests. Today, hackers and script kiddies of various affiliations are expected to begin a campaign of hack attacks and general online disruption against any target that is related to the USA. From previous activity of this sort, the attackers are generally opportunistic in nature and will aim for the low hanging fruit. Attacks may take various forms including the following:

  • DDoS attacks
  • Hack social media accounts and deface or post fake messages
  • Hack organization websites and deface or steal information and post it as “proof” of breach
  • Hack organization servers and attempt sabotage such as planting disk wiping malware
  • Less likely but plausible scenarios could include attacks against...
