Phishing increased 62 percent in '09

Published: March 22, 2010 Reading time: 1 min

The DarkReading site is carrying a story about brand-protection firm MarkMonitor’s finding that phishing increased 62 percent in 2009 with 565,502 attacks in the year. MarkMonitor is based in San Francisco. Other conclusions in MarkMonitor’s 2009 BrandJacking Index report: The huge increase can probably be attributed to the use of botnets and the large amount of personal information that can be scraped from social network sources. 2009 saw the all-time high average of 600 phishing attacks per organization only 33 percent of victims were first-time targets. Social networks suffered 11,240 attacks – two percent of the year’s total. The U.S. hosted 44.7 percent of phishing attacks, up from 36.5 in 2008. DarkReading story Here.

Index of /images: a hiding place for malware?

Published: March 22, 2010 Reading time: 4 min

The underlying structure of a typical website is made up of different folders and sub-folders, much like the ones that are on your computer. A webmaster (is this term still used often lol?) transfers files back and forth using an FTP client in order to update the website. In most cases, specific folders are created for a specific reason. For instance the ‘pub’ folder is usually a public repository that allows anybody access to. ...

I won’t abuse it, I promise…. cross my heart… spit into the wind… etc. Hi folks, Yesterday, I received this SPIM (Instant message spam) … usnews3.com sounds kind of official, doesn’t it? and the page looks impressive… There are lots of links on the page, but unfortunately, a mouse-over of each link reveals that they all go to the same place… That’s not a good sign for a legitimate webpage. Moreover, a whois shows that it was registered just on 7th December 2009, and that the ownership is hidden behind a privacy protector service. ...

The messages look like these: If you follow the link, you end up to a fake Twitter page: If you mistakenly give out your credentials, the attackers will start sending similar Direct Messages to your contacts, posing as you. The ultimate goal of the attackers is to gain access to a large amount of valid Twitter accounts, then use these account to post Tweets with URLs pointing to malicious websites which will take over users computers when clicked. ...

Another FakeAV, for Windows 7!

Published: March 22, 2010 Reading time: 1 min

With Windows 7 becoming increasingly popular, more and more software companies have begun to upgrade their interface for the latest Microsoft operating system. Manufacturers seem to understand the need for a beautiful user interface for their products. However, not all software behaves as good as it looks. Today, I saw a Fake Antivirus program with a newer, more jazzed up interface, which we detect as Troj/FakeAle-RK. This malware specifically targets users of Windows 7 and appears in the form of a pop-up dialogue box, which attempts to tell you that your Windows 7 PC has many serious threats. When a user clicks “Remove all Threats immediately”, another pop-up will be generated asking them to download a file called win_protection_update.exe. ...

The Dangers Of Freebies

Published: March 19, 2010 Reading time: 3 min

The internet is rife with free tools from anything to everything (almost) – from free HTML web editors to free applications to free games and so on. We’ve been in this situation before. Sometimes out of curiosity or “affluenza” (also known as “I-GOTTA-HAVE-IT-NOW-NO-MATTER-WHAT”), we are tempted to install some of these free tools and applications from the web. The unfortunate problem with freebies is that unless you know the source of where you download the tools from and whether the software author who created the application is credible, you are literally at the whim and mercy of the author should you choose to download and install the application. ...

Fraud alert: Tax time in the USA

Published: March 19, 2010 Reading time: 1 min

Benjamin Franklin once wrote, “‘In this world nothing can be said to be certain, except death and taxes.” These days we can add to the certainty of those two inevitable events with the addition of the annual scams that accompany tax time. For those of you who haven’t heard of this type of scam, it’s basically another way to separate a man from his money, or if you want to look at the bigger picture, a way to defraud the federal government. Either way, your wallet suffers. The financial website money-zine has a good article on the latest tax scams you may encounter on the Web. ...

Or is it at the saturation point? The SANS Institute (acronym = SysAdmin, Audit, Network, Security) web site carried a blog piece that gives a good snapshot of the horrible ongoing plague of spam email that IT folks all over the globe must deal with. The writer, Deborah Hale, said the ISP in the Midwest where she works received almost 20 million pieces of email for more than 9,000 accounts since the beginning of March. Only 713,222 (3.6 percent) were NOT spam. ...

iRogue?

Published: March 18, 2010 Reading time: 2 min

Are Mac OS X rogues an emerging threat? For many years discussions of the potential for malware on Macs have ended with the conclusion: “there isn’t much yet, but as soon as Mac gets a big market share the dark side is going to start writing the code.” There are indications that the bad guys are working on it. There have been some blog posts suggesting that the dark side is working hard to create a Mac OS X compatible rogue. SCMagazine is carrying a piece quoting a spokesman for researchers at Intego. Apparently Intego researchers got proof-of-concept code for an OS X rogue from underground sources and determined that it didn’t quite work. However, they concluded that some sophisticated coding was going on: ...

Chilean Earthquake Spawns Malware

Published: March 12, 2010 Reading time: 3 min

Most of us are familiar with how high profile news events are used for malware distribution. We’ve seen it many times such as with Tiger Woods’ scandal and the earthquake in Haiti. Now the recent earthquake in Chile is used to prey upon unsuspecting folks interested in what’s going on with the post-quake and tsunami. This shows we should really be careful in our choices of where we go to get information. Try any related search term or phrase related to “Chile Earthquake”, “Tsunami”, etc. I’ve done so and will walk us through a few examples of risky to malicious content that my search turned up. This type of malware distribution tends to target the broadest audience possible, so I entered the search term “Chile” and then let Google auto-complete my search to “Chile quake 2010 tsunami” to load what is a popular search phrase. Almost immediately, among some recognizable news site results are random blog posts touting words like “download” or “.exe”. We should be suspicious of these. ...

Facebook Users Suffer From ‘Fram’

Published: March 12, 2010 Reading time: 3 min

About a year or so ago one of the “McMarketeers” decided it would be fun to run a campaign against “fram”–spam that friends send you. As you might guess, we in the Labs have no friends, so it was no problem for us to ridicule the idea. However, around the coffee machine the other day I got involved in a quick discussion about spam on Facebook. A long-term social networker genuinely thought that Facebook spam did not exist and that all the noise was from Facebookers playing games or using annoying apps. So I offered to write up an example. ...

Twitter starts Direct Message phishing filtering

Published: March 12, 2010 Reading time: 1 min

Del Harvey who leads Twitter’s Trust and Safety team blogged yesterday that the social networking/micro-blogging service has begun filtering all links in Twitter Direct Messages to stop phishing: “Since these attacks occur primarily on Direct Messages and email notifications about Direct Messages, this is where we have focused our initial efforts. For the most part, you will not notice this feature because it works behind the scenes but you may notice links shortened to twt.tl in Direct Messages and email notifications.” ...

Consoles for old games come with new malcode

Published: March 12, 2010 Reading time: 2 min

Be on the lookout for websites offering up “free applications” which come with a nasty sting in the tail. Here’s a typical example: Appzkeygen(dot)com If you like videogame consoles, you may be a fan of emulators (programs that ape long dead consoles, allowing you to play old games on your PC – we’ll avoid the murky legal minefield that comes with this practice and instead focus on the malware). Below is a Playstation 2 emulator – no really, it is. Would they lie to you? ...
