Recent blast of emails linked to Strom Warm attempt to exploit client-side vulnerabilities by stating that the U.S. army has invaded Iran. The email is also reported to contain links to videos. The text reads:
“Just now US Army’s Delta Force and U.S. Air Force have invaded Iran. Approximately 20000 soldiers crossed the border into Iran and broke down the Iran’s Army resistance. The video made by US soldier was received today morning. Click on the video to see first minutes of the beginning of the World War III. God save us.” more»
Phishing attacks have outnumbered emails infected with viruses and Trojan horse programs for the first time, according to security experts.
...The difference in the ratio of phishing to virus attacks is partly due to virus attacks becoming more targeted and no longer occurring as one large outbreak. This includes the recent Storm Worm and Warezov attacks, according to MessageLabs. more»
Chad White wrote an article for MediaPost about best practices which parallels a lot of thinking I've been doing about how the email marketing industry treats best practices. After several conversations recently about "best practices," I'm convinced that the term is now meaningless. It's been bastardized in the same way that the definition of "spam" has shifted to the point that it has very different meanings to different groups of people. 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»
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»
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»
Return Path published their most recent Global Deliverability report this morning. It shows that inbox placement of mail has decreased 6% in the second half of 2011. This decrease is the largest decrease Return Path has seen in their years of doing this report... Filters are getting more sophisticated. This means they're not relying on simply IP reputation for inbox delivery any longer. more»
It shouldn't be a big surprise to hear that phishing is a big problem for banks. Criminals send email pretending to be a bank, and set up web sites that look a lot like a bank. One reason that phishing is possible is that e-mail has no built in security, so that if a mail message comes in purporting to be from, say, accounts@bankofamerica.com, there's no easy way to tell whether the message is really from bankofamerica.com, or from a crook. 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»
Declan McCullagh reporting in CNET: "The FBI is asking Internet companies not to oppose a controversial proposal that would require the firms, including Microsoft, Facebook, Yahoo, and Google, to build in backdoors for government surveillance. In meetings with industry representatives, the White House, and U.S. senators, senior FBI officials argue the dramatic shift in communication from the telephone system to the Internet has made it far more difficult for agents to wiretap Americans suspected of illegal activities..." more»
There has been a lot of talk about how the DNS can provide network-based security, and how DNS is in the best position to detect malware traffic before it does any harm. But what does this mean for end users? How does it make their online lives easier and more secure? DNS servers that are aware of sites that host malware, perform phishing activities (harvesting bank details, for instance) and other nefarious misbehaviors, can prevent end users from ever going to those sites. more»
We are at an inflection point in our lifetimes. The Internet is broken, seriously broken... Almost all of the systems currently in use on the Internet are based on implicit trust. This has to change. The problem is that these systems are so embedded in our everyday lives that it would be, sort of like, changing gravity, very difficult. more»
