Sopho’s Threat Report Focuses on Social Network Spam

The latest Sophos Threat Report shows an upward trend in spam and identity theft through social networks. One of the examples Sophos gives is Facebook. In general Sophos claims that from 2009 to 2010 the spam, phishing and malware containing messages all doubled. more

Cybercriminals Shifting Focus From Windows PCs to Other Systems and Mobile

In a major cybercrime turning point, scammers have begun shifting their focus away from Windows-based PCs to other operating systems and platforms, including smart phones, tablet computers, and mobile platforms in general, according to the Cisco® 2010 Annual Security Report, released today. The report also finds that 2010 was the first year in the history of the Internet that spam volume decreased, that cybercriminals are investing heavily in "money muling," and that users continue to fall prey to myriad forms of trust exploitation. more

Protecting Yourself from Spear Phishing

One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more

A Closer Look at the Flame/Flamer/sKyWIper Malware

The world is abuzz this week with some flaming malware - well "Flame" is the family name if you want to be precise. The malware package itself is considerably larger than what you'll typically bump into on average, but the interest it is garnering with the media and antivirus vendors has more to do with the kinds of victims that have sprung up - victims mostly in the Middle East, including Iran - and a couple of vendors claiming the malware as being related to Stuxnet and Duku. more

Canadian Government Quietly Pursuing New ISP Code of Conduct

If approved, the code would technically be voluntary for Canadian ISPs, but the active involvement of government officials suggests that most large providers would feel pressured to participate. The move toward an ISP code of conduct would likely form part of a two-pronged strategy to combat malicious software that can lead to cybercrime, identity theft, and other harms. First, the long-delayed anti-spam legislation features new disclosure requirements for the installation of software along with tough penalties for non-compliance. more

Who Has Taken Over As the Most Prolific Botnet Since Rustock Was Taken Down?

Over at the site V3.co.uk, they have an article up today alleging that since the Rustock takedown two weeks ago, the bagle botnet has moved to take over as the botnet that is responsible for sending the most spam. They have not replaced Rustock's total spam volume, only that they are now the number one spam sending botnet. more

The Crimeware Infection Lifecycle

The distribution and installation of malicious and unauthorized software has evolved consistently throughout the 21st Century. The evolutionary path from annoying viruses, to destructive malware and on to financially driven crimeware, is well documented and can even be conveniently traced via the parallel evolution of technologies that were designed to counter each new aspect of the then contemporary threat. more

Mac Hit by Another Wave of Malware… Users in Denial?

In case you haven't been watching cyber news recently, last week various security researchers published that Macs were infected by the Flashback Trojan and that the total number of infections worldwide was 600,000. This number was published by a couple of blogs. I debated writing about this topic since we had a previous Mac outbreak last year that initially spiked up, caused Apple to go into denial about the affair before issuing a fix, and then the malware kind of went away. Will this follow the same pattern? more

What Mobile Malware Looks Like

Last month at the Virus Bulletin Conference in Barcelona, I took in one of the sessions on mobile malware. This type of malware is foreign to me because I mostly stay in the email space at work (and even then, I am focusing more on day-to-day issues of running a large mail provider than I am on spam and abuse). What's mobile malware like? What are the threats? How do users get infected? more

United States Is the Most Bot-Infected Country. Right?

A couple of days ago, Threatpost posted an article indicating that the United States is the most bot-infected country... I think that Microsoft's mechanism of measuring bot infections is a good one, not necessarily because it is the most accurate but because it represents the most complete snapshot of botnet statistics. Because Microsoft Windows is installed on so many computers worldwide and because so many users across the world call home to the MSRT, Microsoft is able to collect a very large snapshot of data. more

.COM - The Riskiest Top-Level Domain? (Part 2)

Following up from my post yesterday, I thought I would take a look at how spammy each particular TLD is. At the moment, I only track 8 TLD's - .cn, .ru, .com, .net, .org, .info, .biz and .name. To check to see which one is the spammiest, I took all of our post-IP blocked mail and determined how many times those messages occurred in email, and how many times that email was marked as spam... more

Hacking Increasingly Becoming a Physical Concern

If this past quarter's stories are any indication, we could very well be seeing the rise of a new wave of threats that will affect people in a more pronounced and physical level, reports Trend Micro in its Q2 Security Roundup Report. more

Microsoft, Fortra, and Health-ISAC Take Legal Action Against the Abuse of Cobalt Strike to Combat Ransomware Attacks

A group of companies, including Microsoft, have collaborated to launch a major action to disrupt the use of cracked, legacy copies of the security tool Cobalt Strike which cybercriminals have abused to deploy ransomware. more

Breaking Down Silos Doesn’t Come Easy

"We need to break down silos", is a phrase often heard in national and international meetings around cyber security and enforcing cyber crime. So it is no coincidence that at the upcoming NLIGF (Netherlands Internet Governance Forum), the IGF, but also an EU driven event like ICT 2013 have "Breaking down silos" and "Building bridges" on the agenda. But what does it mean? And how to do so? more

Global Payments Breach Confirmation

This morning, Global Payments held a conference call with investors and analysts covering their earlier breach announcement and projected earnings. Global Payments had also released an update advisory yesterday stating that "the company believes that the affected portion of its processing system is confined to North America and less than 1,500,000 card numbers have been exported" and that only Track 2 card data may have been stolen. more
