What about the botnets?!

Botnets are a huge problem for a number of reasons. Not only are they used to send spam, they’re also used in criminal activities. One of the major challenges in dealing with botnets is finding and stopping the people who create and use them. Why? Because the internet is global and crime tends to be prosecuted within local jurisdictions. Catching someone running a botnet, or involved in...

Security, safety and the cavalry

In some ways it’s been really hard to focus on email for the last few months. There are so many more important issues in the world. Terrorism, Brexit, the US elections compromised by a foreign government, nuclear threats from multiple countries, the repeal of ACA, mass deportations and ICE raids here in the US.  I find myself thinking about what to blog. Then I glance at the news and wonder...

Anatomy of a successful phishing attempt

Earlier this year the Exploratorium was the victim of a phishing attack. They’ve posted an article on what happened and how they discovered and dealt with the issue. But they didn’t just report on the attack, they dissected it. And, as is appropriate for a organization with a mission of education, they mapped out what they discovered during the investigation. There are a couple of...

Abuse, triage and data sharing

The recent subscription bombs have started me thinking about how online organizations handle abuse, or don’t as the case may be. Deciding what to address is all about severity. More severe incidents are handled first. Triage is critical, there’s never really enough time or resources to investigate abuse. What makes an event severe? The answer is more complicated that one might think...

The 2nd Circuit Court of Appeals ruled against the Government today in US Government vs. Microsoft. The government is investigating a drug dealer and want access to records held by Microsoft. Microsoft turned over metadata stored on US machines. But they refused to turn over the specific emails stored on machines in Dublin. The company’s position is that the federal government needs to...

Sanford Wallace goes to Jail

Sanford Wallace has been sentenced to 2 years in jail by the US District court in San Jose for contempt of court and electronic mail fraud. Sanford has been around for more than 2 decades. He is one of the spammers that drove me to learn how to read headers and report spam back in the late nineties. Sanford has been in and out of courts and the news almost as long as he’s been spamming...

Phishing costs company $46 million

Brian Krebs posted about a tech firm that lost $46M dollars due to fraud. The company reported in its SEC filings that the money was lost when someone impersonated an employee and directed the finance department to transfer money to outside accounts. This is becoming more common. In some cases, DMARC authentication may stop this kind of fraud. But DMARC has a lot of deployment challenges and can...

Filtering is not just about spam

A lot of filters started out just as filters against spam. But over the years they’ve morphed into more general blocks against dangerous or problematic email. There’s a lot of crime and bad behavior on the internet, much of it using email as a conduit or vector. Filtering is so much more than stopping spam now. It’s as much, or more, about stopping crime. Email filters are...

Email marketing firm smacked by the SEC

Yes, the SEC. Really. Apparently the email marketing firm mUrgent, which provides services to the restaurant and hospitality industry also had a side business. According to the complaint filed by the SEC last month, they had an entire boiler room set up to sell shares for their non-existent IPO. I’d never heard of this firm before, so I did a little digging. First step, check out their...
