Mainsleaze is nerdy slang for spam sent by large, well-known, otherwise reputable organizations. Although the volume of mainsleaze is dwarfed by the volume of spam for fake drugs, account phishes, and Nigerian 419 fraud, it causes work for mail managers far out of proportion to its volume... The problem with mainsleaze is that it is generally mixed in with mail that the recipients asked for, and there's no way to tell the difference mechanically. more»
The "Carbon Footprint of e-mail Spam Report" estimated that 62 trillion spam emails are sent globally every year. This amounted to emissions of more than 17 million tons of CO2, the research by climate consultants ICF International and anti-virus firm McAfee found. Searching for legitimate emails and deleting spam used some 80% of energy. more»
In a perfect world, consumers recognize authentic emails from fake, update their operating system, browser and anti-virus software, and have a healthy skepticism about the safety of the Internet. The bad guys hate perfect, so we should be working with consumers to stop them. ... Organizations like mine are joining forces to recruit consumers -- who are also your customers and employees -- in the fight against cybercrime. more»
Spamhaus has switched legal tack and decide to appeal an $11.7m judgment against it by a US court obtained by a firm it labelled a spammer. ...In a default ruling made by a US court last month, Spamhaus was ordered to pay $11.7m in compensation to e360 Insight, pull the organisation's listing and post a notice stating that it was wrong to say e360 Insight was involved in sending junk mail. Spamhaus did not defend the case and the ruling was made in its absence. more»
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»
ICANN has agreed that only registrars can suspend individual domain names. It believes that there is no way it could enforce the proposed court order. But as the organization responsible for the Internet's top-level domains, ICANN does have the authority to accredit registrars like Tucows, based in Toronto.
Princeton University's Edward Felten believes it is possible that ICANN could be forced to comply with this type of court order. more»
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»
For email usage, abuse reporting requires cooperation between senders and receivers. That's why RFC 5965 specified a standard format for it. However, Wikipedia lists only 18 feedback providers today. It is often said that the number of legitimate mailbox providers in the world is rather small, possibly some hundreds of thousands, but certainly more than that. more»
Mobile networks aren't usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are. This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits more»
I wonder how much botnets reuse IP addresses. Do they infect a system and spam, get blocked, discard the IP and move onto the next (new) one? This means that they have a nearly unlimited supply of IP addresses. Or do they infect a system and spam, get blocked, and then let it go dormant only to awaken it some time later? I decided to take a look. more»
Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more»
Courtesy forwards have been a standard feature of e-mail systems about as long as there have been e-mail systems. A user moves or changes jobs or something, and rather than just closing the account, the mail system forwards all the mail to the user's new address. Or a user with multiple addresses forwards them all to one place to be able to read all the mail together. Since forwarding is very cheap, it's quite common for forwards to persist for many years. Unfortunately, forwarding is yet another thing that spam has screwed up. more»
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»
Microsoft took down a Zeus botnet recently. Within days it was publicly accosted by Fox-IT's director Ronald Prins for obstructing ongoing investigations and having used Fox-IT's data. This was followed by the accusation that Microsoft obstructs criminal proceedings... On top of all this EU Commissioner Cecilia Malmström announced that cooperation between law enforcement and industry will be forged in the European Cyber Crime Centre as of 2013. Coincidences do not exist. Why? more»
I recently had a chance to read a report titled, "Show Me the Money: Characterizing Spam-advertised Revenue" produced as a joint effort from the University of California, San Diego (UCSD), International Computer Science Institute, and UC Berkeley by Chris Kanich, Nicholas Weaver, Damon McCoy, Tristan Halvorson, Christian Kreibich, Kirill Levchenko, Vern Paxson, Geoffrey M. Voelker and Stefan Savage. I also had a chance to hear Chris Kanich speak about the topic - Show Me The Money! This post contains my notes with some photos taken from that report. more»
