You may want to skip the tens of thousands of malicious emails currently in circulation, attempting to trick users into executing the malicious attachment. Once downloaded, your PC automatically joins the botnet operated by the cybercriminal(s) behind the campaign, undermining the confidentiality and integrity of the host.

Cybercriminals are currently mass mailing tens of thousands of malicious emails, supposedly including a photo attachment that’s been “Sent from an iPhone”. The social engineering driven spam campaign is, however, the latest attempt by a cybercriminal/group of cybercriminals that we’ve been monitor for a while, to attempt to trick gullible users into unknowingly joining the botnet operated by the malicious actor(s) behind the campaign.
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.
Our sensors just picked up an interesting Web site infection that’s primarily targeting Brazilian users. It appears that the Web site of the Brazilian Jaqueira prefecture has been compromised, and is exposing users to a localized (to Portuguese) Web page enticing them into installing a malicious version of Adobe’s Flash player. Not surprisingly, we’ve also managed to identify approximately 63 more Brazilian Web sites that are victims to the same infection.
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.
In a professional cybercrime ecosystem, largely resembling that of a legitimate economy, market participants constantly strive to optimize their campaigns, achieve stolen assets liquidity, and most importantly, aim to reach a degree of efficiency that would help them gain market share. Thus, help them secure multiple revenue streams. Despite the increased transparency on the Russian/Easter European underground market — largely thanks to improved social networking courtesy of the reputation-aware cybercriminals wanting to establish themselves as serious vendors — certain newly joining vendors continue being a victim of their market-irrelevant ‘biased exclusiveness’ in terms of the unique value propositon (UVP) presented […]
From Bitcoin accepting services offering access to compromised malware infected hosts and vertical integration to occupy a larger market share, to services charging based on malware executions, we’ve seen multiple attempts by novice cybercriminals to introduce unique value propositions (UVP). These are centered on differentiating their offering in an over-supplied cybercrime-friendly market segment. And that’s just for starters. A newly launched service is offering access to malware infecting hosts, DDoS for hire/on demand, as well as crypting malware before the campaign is launched. All in an effort to differentiate its unique value proposition not only by vertically integrating, but also emphasizing […]
WhatsApp users, watch out! The cybercriminal(s) behind the most recently profiled campaigns impersonating T-Mobile, and Sky, have just launched yet another malicious spam campaign, this time targeting WhatsApp users with fake “Voice Message Notification/1 New Voicemail” themed emails. Once unsuspecting users execute the fake voice mail attachment, their PCs will attempt to drop additional malware on the hosts. The good news? We’ve got you (proactively) covered.
Thanks to the growing adoption of mobile banking, in combination with the utilization of mobile devices to conduct financial transactions, opportunistic cybercriminals are quickly capitalizing on this emerging market segment. Made evident by the release of Android/BlackBerry compatible mobile malware bots. This site is empowering potential cybercriminals with the necessary ‘know-how’ when it comes to ‘cashing out’ compromised accounts of E-banking victims who have opted-in to receive SMS notifications/phone verification, whenever a particular set of financial events take place on their bank accounts. A new commercially available Android, BlackBerry (work in progress) — supporting mobile malware bot is being pitched by […]
A currently ongoing malicious spam campaign is attempting to trick users into thinking that they’ve received a legitimate Excel ‘Company Reports’ themed file. In reality through, once socially engineered users execute the malicious attachment on their PCs, it automatically opens a backdoor allowing the cybercriminals behind the campaign to gain complete access to their host, potentially abusing it a variety of fraudulent ways.
