DIY Python-based mass insecure WordPress scanning/exploting tool with hundreds of pre-defined exploits spotted in the wild

by

Throughout 2013, we not only witnessed the re-emergence of proven mass, efficiency-oriented Web site hacking/exploitation tactics, such as, the reliance on Google Dorks scanning, good old fashioned brute-forcing, but also, the introduction of new concepts, successfully utilizing/standardizing, both, compromised accounting data, and server-farm level access, in an attempt to fraudulently monetize the hijacked traffic from legitimate Web sites. As we’ve seen on numerous occasions throughout the years, despite sophisticated ‘innovations’, cybercriminals are no strangers to the KISS (Keep It Simple Stupid) principle. Case in point in terms of Content Management Systems (CMSs) is WordPress, whose market share is naturally proportional with […]

Cybercrime Trends 2013 – Year in Review

by

It’s that time of the year! The moment when we reflect back on the cybercrime tactics, techniques and procedures (TTPs) that shaped 2013, in order to constructively speculate on what’s to come for 2014 in terms of fraudulent and malicious campaigns, orchestrated by opportunistic cybercriminal adversaries across the globe. Throughout 2013, we continued to observe and profile TTPs, which were crucial for the success, profitability and growth of the cybercrime ecosystem internationally, such as, for instance, widespread proliferation of the campaigns, professionalism and the implementation of basic business/economic/marketing concepts, improved QA (Quality Assurance), vertical integration in an attempt to occupy […]

Top 5 Enterprise Threat Predictions for 2014 Ransomware for the enterprise Compromised clouds Advanced mobile phishing tactics APT’s focus on mobile Mobile device linked to major compromise When thinking about cyber-security and looking back over the years, there is a clear and unfortunate trend which doesn’t show any signs of slowing. The trend is that year over year, more and more cyber-attacks occur while at the same time, the sophistication of attacks continues to evolve. Additionally, a matured cyber-crime as a service (CCaaS) ecosystem has enabled practically anyone to get involved. Combine this with the growing cost of defenses and […]

Malicious multi-hop iframe campaign affects thousands of Web sites, leads to a cocktail of client-side exploits – part two

by

Ever since we exposed and profiled the evasive, multi-hop, mass iframe campaign that affected thousands of Web sites in November, we continued to monitor it, believing that the cybercriminal(s) behind it, would continue operating it, basically switching to new infrastructure once the one exposed in the post got logically blacklisted, thereby undermining the impact of the campaign internationally. Not surprisingly, we were right. The campaign is not only still proliferating, but the adversaries behind it have also (logically) switched the actual hosting infrastructure. Let’s dissect the currently active malicious iframe campaign that continues to serving a cocktail of (patched) client-side […]

Malicious multi-hop iframe campaign affects thousands of Web sites, leads to a cocktail of client-side exploits

by

Sharing is caring. In this post, I’ll put the spotlight on a currently circulating, massive — thousands of sites affected — malicious iframe campaign, that attempts to drop malicious software on the hosts of unaware Web site visitors through a cocktail of client-side exploits. The campaign, featuring a variety of evasive tactics making it harder to analyze, continues to efficiently pop up on thousands of legitimate Web sites. Ultimately hijacking the legitimate traffic hitting them and  successfully undermining the confidentiality and integrity of the affected users’ hosts.

Low Quality Assurance (QA) iframe campaign linked to May’s Indian government Web site compromise spotted in the wild

by

We’ve intercepted a currently trending malicious iframe campaign, affecting hundreds of legitimate Web sites, that’s interestingly part of the very same infrastructure from May, 2013′s analysis of the compromise of an Indian government Web site. The good news? Not only have we got you proactively covered, but also, the iframe domain is currently redirecting to a client-side exploit serving URL that’s offline. Let’s provide some actionable intelligence on the malicious activity that is known to have originated from the same iframe campaign in the past month, indicating that the cybercriminal(s) behind it are actively multi-tasking on multiple fronts.

New cybercrime-friendly iFrames-based E-shop for traffic spotted in the wild

by

Thanks to the free, commercial availability of mass Web site hacking tools, in combination with hundreds of thousands of misconfigured and unpatched Web sites, blogs and forums currently susceptible to exploitation, cybercriminals are successfully monetizing the compromise process. They are setting up iFrame based traffic E-shops and offering access to hijacked legitimate traffic to be later on converted to malware-infected hosts. Despite the fact that the iFrame traffic E-shop that I’ll discuss in this post is pitching itself as a “legitimate traffic service”, it’s also explicitly emphasizing on the fact that iFrame based traffic is perfectly suitable to be used […]

Cybercriminals are mass mailing tens of thousands of malicious Federal Deposit Insurance Corporation (FDIC) themed emails, in an attempt to trick users into clicking on the client-side exploits serving and malware dropping URLs found in the bogus emails. Let’s dissect the campaign, expose the portfolio of malicious domains using it, provide MD5s for a sample exploit and the dropped malware, as well as connect the campaign with previously launched already profiled malicious campaigns.

Cybercrime-friendly underground traffic exchanges help facilitate fraudulent and malicious activity – part two

by

The list of monetization tactics a cybercriminal can take advantage of, once they manage to hijack a huge portion of Web traffic, is virtually limitless and is entirely based on his experience within the cybercrime ecosystem. Through the utilization of blackhat SEO (search engine optimization), RFI (Remote File Inclusion), DNS cache poisoning, or direct impersonation of popular brands in spam/phishing campaigns tactics, on a daily basis, traffic is sold and resold for achieving a customer’s or a seller’s fraudulent/malicious objectives, and is then most commonly converted to malware-infected hosts. In this post, I’ll profile two cybercrime-friendly iFrame traffic exchanges, with the […]
