First, this is not a blog about a big corporate breach, or a massive new discovery. Rather, the researchers at Trustwave gained access to a botnet controller interface (the C&C element of a botnet) known as Pony and revealed the data within. Not surprisingly, as the vast majority of botnets target user credentials, this controller had a good deal of data related to passwords. While 2 million passwords might seem like a lot, it is really a drop in the bucket compared to many recent breaches. Think about Adobe who lost a minimum of 28 million, but is rumored to […]

Have you received a casual-sounding email enticing you into signing a Billing Address Code (BAC) form for October, in order for the Payroll Manager to proceed with the transaction? Based on our statistics, tens of thousands of users received these malicious spam emails over the last 24 hours, with the cybercriminal(s) behind them clearly interested in expanding the size of their botnet through good old fashioned ‘casual social engineering’ campaigns.
Over the last two months, we’ve been closely monitoring — and proactively protecting from — the malicious campaigns launched by cybercriminals who are no strangers to the concept of social engineering topic rotation. Their purpose is to extend a campaign’s life cycle, or to generally increase a botnet’s infected population by spamming out tens of thousands of fake emails, exposing users to malicious software. The most recent campaign launched by the same cybercriminal(s), is once again impersonating T-Mobile U.K in an attempt to trick mobile users into thinking that they’ve received a legitimate MMS Gallery notification. In reality though, once the […]
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.
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 […]
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.
British users, watch what you execute on your PCs! Over the last week, cybercriminals have launched several consecutive malicious spam campaigns targeting users of Sky, as well as owners of Samsung Galaxy devices, into thinking that they’ve received a legitimate MMS notification to their email address. In reality though, these campaigns ‘phone back’ to the same command and control botnet server, indicating that they’re related.
