US Continues to Lead As Top Country Hosting Phishing Attacks

Recent study indicates that US continues to widen its lead as the number one country when it comes to hosting phishing sites. According to the latest Brandjacking Index just released by MarkMonitor, US-hosted phishing sites grew by ten percent from last quarter -- up from 36 percent to 46 percent. Canada is now at second position with 4.7 percent of all phishing attacks, followed by the Russian Federation (4.5 percent), France (4 percent), and Denmark (4 percent). more

Blacklist Operations and Practices: Excerpts from an ASRG Draft

The Anti-Spam Research Group (ASRG) published a draft for an Overview of Email DNSBL Best Practices. We can take a step back and review paragraph 2.2.5 (Conflict of Interest)... Some DNSBLs used for blocking/negative reputation have had a practice of requiring fees or donations to charities from the listee for delisting. It is generally considered entirely appropriate for a DNSBL to charge for access to it by its users -- the definition of a commercial DNSBL. more

Rustock, Xarvester Spambots Capable of Sending 25,000 Messages Per Hour, Says New Study

A recent study suggests Rustock and Xarvester malware provided the most efficient spambot code, enabling individual zombie computers to send 600,000 spam messages each over a 24 hour period. "Over the past few years, botnets have revolutionized the spam industry and pushed spam volumes to epidemic proportions despite the best efforts of law enforcement and the computer security industry. Our intention was to better understand the origins of spam, and the malware that drives it," said Phil Hay, senior threat analyst, TRACElabs (a research arm of security company Marshal8e6)... more

Q3 Saw Massive Virus Volumes While Spam Remained Steady

Spam and virus trends in Q3'10 confirm that spammers are still hard at work distributing malicious content in new and creative ways, according to the latest reports. The latest spam and virus trends report is produced by Postini, Google's email security and archiving service that, according to the company, processes more than 3 billion email messages per day and more than 50,000 businesses. more

Searching for Truth in DKIM: Part 5 of 5

Throughout this series of articles we've been talking about DKIM, and what a valid DKIM signature actually means. .. What this means for senders (of any type) is that with DKIM, you’re protected. On the internet, your domain name is a statement of your brand identity – so by signing messages with DKIM, you can finally, irrevocably tie those messages to your brand. more

Spam Bouncing Back to Original Levels Despite Major Shutdowns

Average level of spam in the second quarter of 2009 has risen by 53 percent, as compared to the first quarter of this year, according to latest report from Google's email security and archiving services group, Postini. The report foresees unpredictable pattern of drops and spikes for the rest of the year... more

Taking Permission

Permission is always a hot topic in email marketing. Permission is key! the experts tell us. Get permission to send email! the ISPs tell us. Marketers have responded by setting up processes to "get" permission from recipients before adding them to mailing lists. They point to their privacy polices and signup forms and say "Look! the recipient gave us permission." In many cases, though, the permission isn't given to the sender, permission is taken from the recipient. more

Review Your Email Forwarding Practices

As unusual as it may be for a lawyer to speak at a IETF meeting, Ian Walden gave a lecture on Data Protection Directives and updates thereof. He said they affect some 90 jurisdictions. A difference between email addresses and cookies - the latter are the main subject of the January 2012 update of the directives - is that after more than a decade of enforcement, specific browser extensions may allow users to browse what cookies they have, while no record states whom they conferred their email addresses to. more

VoIP Security FUD

I'm continually amazed by the amount of FUD being spread with regard to VoIP security threats. People...the sky is not falling. VoIP isn't e-mail. It isn't implemented like e-mail, it won't be implemented like e-mail (maybe "it shouldn't be implemented like e-mail" is a more appropriate statement). Following best security practices will ensure at least a level of security equivalent to current TDM systems. Best FUD I've heard this week: VoIP is insecure because you can simply put a bridge on an ethernet line and capture a stream. Hey, has anyone ever heard of alligator clips? more

ACMA: 30,000 PC’s Infected in Australia Per Day

Anti-spam and malware enforcement agency ACMA reports on this (shocking high?) figure. Keep this up and ca. 50% of the Australian population is infected within a year. I remember a presentation from Sweden only a few years ago, that there were only a little over a thousand infected pc's in Sweden. (Reactions were: that can't be correct. Too low) Do you know what the numbers are for your country and maybe more importantly what your government and/or Industry is/are doing about it? more

Correlation Between Country Governance Regimes & Reputation of Their Internet Address Allocations

We recently analyzed the reputation of a country's Internet (IPv4) addresses by examining the number of blacklisted IPv4 addresses that geolocate to a given country. We compared this indicator with two qualitative measures of each country's governance. We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses. more

Study Indicates Spammers Turning Profit Despite One in 12.5m Response Rates

A recent study has revealed some of the economics behind junk mail and spam conversion rates conducted in early 2008 by computer scientists from University of California, Berkeley and UC, San Diego (UCSD). The analysis has suggested that spam operations are able to remain profitable and generate millions from minute response rates. The study is described as the first large-scale quantitative study of spam conversion. more

New Research Finds Over 80% of Domain Names Used by Phishers Are Legitimate Domains

New research from the Anti-Phishing Working Group (APWG) has found that up to 81% of domain names used for phishing are legitimate domains that have been hacked. More specifically, out of the 30,454 phishing domains under observation, only 5,591 domain names (18.5%) were registered by phishers according to APWG. The remaining small percentage of the domains used in phishing belonged to subdomain resellers such as ISPs and other web-based services. more

Spam Peaked at 200 Billion per Day in 2008, Botnets Nexus of Criminal Activity, Says Cisco

In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more

A Flurry of CAN-SPAM Activity: Is It Meaningful?

Our four-year old oft maligned anti-spam legislation in this country, the CAN-SPAM act, has seen an uptick of activity this past week. Melinda Krueger sums up the sentiments of many in the anti-spam community in her Email Insider column today when she says, "there is no provision in the act against sending unsolicited email as long as you comply with the rest of the act. The motivation of the act was more to make voters feel politicians were doing something about this annoying problem." more
