Phishing campaign targeting Gmail, Yahoo, AOL and Hotmail spotted in the wild

Phishing campaign targeting Gmail, Yahoo, AOL and Hotmail spotted in the wild

Cybercriminals are masters of multi-tasking. For instance, whenever a web server gets compromised, they will not only use its clean IP reputation to host phishing, spam and malware samples on it, they will also sell access to the shell allowing other cybercriminals the opportunity to engage in related malicious activities such as, mass scanning of remotely exploitable web application vulnerabilities.

Today, I intercepted a currently active phishing campaign that’s a good example of a popular tactic used by cybercriminal known as ‘campaign optimization’. The reason this campaign is well optimized it due to the fact that as it simultaneously targets Gmail, Yahoo, AOL and Windows Hotmail email users.

117,000 unique U.S visitors offered for malware conversion

117,000 unique U.S visitors offered for malware conversion

In 2012 it’s becoming increasingly common for cybercriminals to apply basic quality assurance (QA) tactics to their campaigns. Next to QA, they also emphasize on campaign optimization strategies allowing them to harness the full potential of the malicious campaign.

Recently, I came across to an underground forum advertisement selling access to 117,000 unique U.S visitors — stats gathered over a period of 8 hours — for the purpose of redirecting them to a Black Hole web malware exploitation kit landing URL. The traffic aggregation taking place through black hat SEO (search engine optimization), is aiming to exploit a group of users known to have high purchasing power, namely, American citizens.

Are such underground market propositions offering traffic exchange deals gaining popularity, or are they just a fad? What’s the infection rate for 117,000 U.S based users redirected to a BlackHole exploits serving landing URL? Let’s find out.

FakeAV for Android! There you are!

FakeAV for Android! There you are!

By Nathan Collier

Every super hero has an arch nemesis. For a lot of Threat Researchers, including myself, Rogue Security Products, or better known as FakeAV, is theirs. Back in the day when I was primarily a PC malware fighter, FakeAV was a prevalent threat that was always coming up with new ways to infect users nearly every other day. I knew it was only a matter of time that the same malware authors would turn mobile. I am afraid those days are upon us. How could I ever forget such an identifiable logo:

“Android Security Suite Premium”… yeah, right!  This spy which is being called Android.FakeSecSuit   retrieves incoming sms messages, extracts the phone number and message, and then sends the stolen info off:

As you can see in the GET command from the PCAP, highlighted in blue is the phone number and message I sent to my test phone now being sent off to a site.

Now that the developers of the popular FakeAV malware have entered into the mobile world expect to to see a lot more variations of this… and if they follow the same pattern as they did in the PC world, I mean A LOT! We are seeing it in Torrents and/or alternative markets. Remember, when downloading Android apps choose them wisely and download  from a trusted source. Check reviews, research the developer and verify  permissions requested before downloading. And of course, scan with Webroot SecureAnywhere Mobile.
