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 exploits, to users visiting legitimate Web sites.
