An industry conference is always a good place to learn and get updates on the latest security trends. I recently attended the Symposium on Security for Asia Network (SyScan), an annual conference held in Singapore, which brings together computer security researchers from around the world. This year, security myths were dispelled and several interesting topics were discussed at the conference. The following is a list of some of the topics and demonstrations I found interesting at this year’s conference.

Smart cars at risk
Most cars today contain Engine Control Units (ECUs), computers that enable the engine to communicate with other vehicle components. Researchers at SyScan 2014 explained how they managed to simulate a car environment on their desktop using second-hand ECU devices purchased from online Web stores. The researchers managed to...

Easter, like all other celebrations is meant to be a day of jubilation, which of course means gifts, shopping, and spreading cheer. However, cheer is not the only thing that is being spread this holiday. Spammers have also started spreading their handiwork. With just a few days left before Easter, the volume of spam is on the rise.

Each year Symantec observes certain categories of spam using Easter as a theme and this year is no different. Let’s take a look at some of the different types of spam Symantec sees year-over-year, as well as some samples from this year.

Replica goods spam
With gifts being at the core of many major celebrations, product spam (replica goods spam in particular) is the spam category Symantec observes the most. In this spam, items such as fake watches and jewelry are promoted using catchy subject lines and product images. Email header examples include:

From: "WorldOfWatches"...

A variation on the 419 email scam is being used by fraudsters to take advantage of couples desperate to adopt a child. Once they are carefully lured into a fake adoption process, the victims are then asked for money to cover legal and administrative fees.

While most recent 419 scams rely more on the naivety of victims than any ingenuity on the part of the spammer, some fraudsters are beginning to make more of an effort to directly communicate with the victim to secure their confidence. Their scams are well researched, convincingly presented and may borrow stories from real life to make their stories more authentic and better able to withstand a little scrutiny.

While fake adoption scams have been seen from time to time before, in this instance Symantec observed real life...

Politicians are frequently featured on phishing sites and in light of the ongoing general election in India, phishers are starting to target Indian users by using a local politician and his party as bait. 

Symantec recently observed a phishing site which spoofs Facebook’s appearance and includes Arvind Kejariwal, the former chief minister of New Delhi and leader of the Aam Aadmi Party. The phishing site was hosted on servers based in Lansing, Michigan in the US.

As seen in the previous image, the phishing site, titled “Unite With Us Against Corruption”, uses a poster of the Aam Aadmi Party along with a fake Facebook “like” button. The site’s background image is a picture of the party’s leader Arvind Kejariwal...

Over the last week, Instagram scammers have been posting images offering fake lottery winnings to followers. They have convinced users to share the posts, give up personal information, and even send money back to the scammers.

In this scam, a number of Instagram accounts have been created to impersonate real-life lottery winners from the UK and US. These accounts claim to offer US$1,000 to each Instagram user who follows them and leaves a comment with their email address.

The accounts impersonating lottery winners have been extremely successful, and have gained anywhere from 5,000 to 100,000 followers.

Once they have amassed a certain number of followers, they reveal a secondary Instagram account belonging to their “accountant”, who is in charge of...

Phishers continuously come up with various plans to enhance their chances of harvesting users’ sensitive information. Symantec recently observed a phishing campaign where data is collected through a fake voting site which asks users to decide whether boys or girls are greater.

The phishing page, hosted on a free web hosting site, targets Facebook users and contains a fake voting campaign, “WHO IS GREAT BOYS OR GIRLS?” along with the “VOTE” button to register votes. The page is also embedded with pair of bar charts representing voting ratio and displays the total votes gained for the last four years. These give a more legitimate feel to the fake application.

In this blog detailing how spammers continue to change their messages in order to increase their success rate, we looked at the evolution of the same spam campaign from missed voicemail messages to spoofing various retailers, and then spoofing utility statements. Clicking on the link led the users to a download for a .zip file containing Trojan.Fakeavlock. Attackers may have realized that those attack vectors no longer entice recipients, so spammers have introduced two new schemes for this campaign that appear to be random and unrelated at first, but they do share a common goal.

The first scheme spoofs various courts around the country:

One of the most popular methods of spamming is snowshoe spam, also known as hit and run spam. This involves spam that comes from many IP addresses and many domains, in order to minimize the effect of antispam filtering. The spammer typically sends a burst of such spam and moves to new IP addresses with new domains. Previously used domains and IP addresses are rarely used again, if ever.

Some spammers like to use a similar pattern across their spam campaigns. This blog discusses a particular snowshoe spam operation that I have labeled “From-Name snowshoe”. While there are other features in the message that allow the campaigns to be grouped into the same bucket, the messages’ most distinct feature is that all of the email addresses that appear in the “from” line use real names as their usernames.

China is gearing up to usher in the Year of the Horse, which begins with the new moon on January 31 this year. With more than a billion people worldwide preparing to celebrate the new year for the lunar calendar, the celebration this year promises more color than ever before.
 
Chinese New Year, also known as the spring festival, is a day for reunion and thanksgiving, where exchanging gifts is at the heart of the celebration. Friends, family, colleagues and even businesses exchange gifts to show love, respect and loyalty. Business owners often send gifts to their customers and shops offer gifts and discounts to show their gratitude. However, spammers are all too aware of this practice.
 
The spammers and fraudsters are known to capitalize on special occasions and exploit the noble gesture of giving gifts in order to send out spam. They are known to pose as friends and business owners and send emails promising gifts and...

After a long hiatus, spammers are once again using an old trick, where they attach a .zip file to trick the user into executing the compressed malware. The chart below shows the number of spam messages with .zip attachments over the last 90 days in Symantec’s Global Intelligence Network (GIN).

On January 7, 99.81 percent of the .zip attachment spam that came into Symantec’s GIN had the file name “BankDocs-”  followed by 10 hexadecimal characters.
