Despite the fact that the one-to-many type of malicious campaign continues dominating the threat landscape, cybercriminals are constantly looking for new ways to better tailor their campaigns to the needs, wants, and demands of potential customers. Utilizing basic marketing concepts such as localization, market segmentation, as well as personalization, today’s sophisticated cybercriminals would never choose to exclusively specialize in one-to-many or one-to-one marketing communication strategies. Instead, they will multitask in an attempt to cover as many market segments as possible.
In this post, I’ll emphasize on a targeted attacks potentially affecting Steams’ users, thanks to the commercial availability of a DIY (do it yourself) Steam ‘information harvester/mass group inviter’ tool, currently available at multiple cybercrime-friendly online communities. What’s so special about the application? How would cybercriminals potentially use it to achieve their fraudulent objectives? How much does it cost? Is the author/vendor of the application offering access to its features as a managed service?
Yesterday, a relatively unknown group of cybercriminals publicly announced the availability of a new Web malware exploitation kit. What’s so special about it is the fact that its current version is entirely based on Java exploits (CVE-2012-1723 and CVE-2013-0431), naturally, with “more exploits to be introduced any time soon”.
Let’s take a peek at the statistics and infection rates produced by this kit, as well as discuss its potential, or lack thereof, to cause widespread damage to endpoints internationally.
A cybercriminal/gang of cybercriminals that we’ve been closely monitoring for a while now has just launched yet another spam campaign, this time impersonating the “Data Processing Service” company, in an attempt to trick its customers into interacting with the malicious emails. Once they do so, they are automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
In this post, I’ll profile their latest campaign and the dropped malware. I will also establish a direct connection between this and three other previously profiled malicious campaigns, as well as an ongoing money mule campaign, all of which appear to have been launched by the same cybercriminal/gang of cybercriminals.
On a periodic basis, cybercriminals are spamvertising malicious campaigns impersonating Verizon Wireless to tens of thousands of Verizon customers across the globe in an attempt to trick them into interacting with the fake emails. Throughout 2012, we intercepted two campaigns pretending to come from the company, followed by another campaign intercepted last month. This tactic largely relies on the life cycle of a particular campaign, intersecting with the publicly generated awareness of its maliciousness.
In this post, I’ll profile one of the most recently spamvertised campaigns impersonating Verizon Wireless. Not surprisingly, once users click on any of the links found in the malicious emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
Over the last couple of days, we’ve been monitoring a persistent attempt to infect tens of thousands of users with malware through a systematic rotation of multiple social engineering themes. What all of these campaigns have in common is the fact that they all share the same malicious infrastructure.
Let’s profile one of the most recently spamvertised campaigns, and expose the cybercriminals’ complete portfolio of malicious domains, their related name servers, dropped MD5 and its associated run time behavior.
Its tax season and cybercriminals are mass mailing tens of thousands of IRS (Internal Revenue Service) themed emails in an attempt to trick users into thinking that their income tax refund has been “turned down”. Once users click on any of the links found in the malicious emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
Cybercriminals are currently spamvertising two separate campaigns, impersonating Facebook Inc., in an attempt to trick its users into thinking that their Facebook account has been disabled. What these two campaigns have in common is the fact that the client-side exploits serving domains are both parked on the same IP. Once users click on any of the links found in the malicious emails, they’re exposed to the client-side exploits served by the Black Hole Exploit Kit.
Cybercriminals are currently attempting to trick Kindle owners into thinking that they’ve received a receipt from an E-book purchase from Amazon.com. In reality, when users click on any of the links found in the malicious emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
In December, 2012, we intercepted a professional-looking email that was impersonating Facebook Inc. in an attempt to trick its users into thinking that they’ve received an “Account Cancellation Request“. In reality, once users clicked on the links, their hosts were automatically exploited through outdated and already patched client-side vulnerabilities, which dropped malware on the affected PCs.
Over the past 24 hours, cybercriminals have resumed spamvertising tens of thousands of legitimate-looking Facebook themed emails, once again using the same social engineering theme.
Users of FedEx’s Online Billing service, watch out!
Cybercriminals are currently mass mailing tens of thousands of emails impersonating the company, in an attempt to trick its customers into clicking on exploits and malware dropping links found in the legitimate-looking emails.
