Email in crosshairs

A Stranger Can Find Out Where You Are By Getting You To Open An Email – On The Media

The ability to use remotely loaded images in HTML emails for tracking has been known for years, but perhaps not widely known.

The On The Media: TLDR podcast just re-surfaced the issue in the above article, where they talk about a free Gmail plugin called Streak, which provides this capability.

It automatically embeds the hidden images in emails you send, then lets you see when and even where the recipient opens them.

Because they appear to use IP address based locations, you can block the “where” part by using Anonymizer Universal.

You can block this tracking completely by turning off the loading of images in your emails. Of course, if you then choose to load images, know that you are also enabling tracking. If you block image loading you will also find that your email become much less attractive and significantly more difficult to read.

Welcome to Episode 11 of The Privacy Blog Podcast, brought to you by Anonymizer.

In this episode, I’ll discuss the shutdown of secure email services by Lavabit and Silent Circle. In addition, we’ll dive into the problem with hoarding Bitcoins and how you can protect yourself while using the increasingly popular online currency. Lastly, I’ll chat about whether teens actually care about online privacy and an ad agency’s shocking decision to use high-tech trash cans to measure Wi-Fi signals in London.

Please leave any questions or feedback in the comments section. Thanks for listening.

There has been a lot of chatter about implications of first Lavabit and then Silent Circle’s Silent Mail being shut down by their operators.

In both cases, it appears that there was information visible to the services which could be compelled by search warrants, court orders, or national security letters.

I want to assure Anonymizer users that we have no such information about Anonymizer Universal users that could be compelled. While we know who our customers are, for billing purposes, we have no information at all about what they do.

This has been tested many times, under many different kinds of court orders, and no user activity information has ever been provided, or could be provided.

Email Privacy Hearing Set To Go Before The House On Tuesday | WebProNews

The House Judiciary Committee is going to be discussing the Electronic Communications Privacy Act. There is a chance that they will strengthen it.

This act was written decades ago, before there were any real cloud solutions. Email was downloaded by your email client, and immediately deleted from the server. They law assumed that any email left on a server more than 180 days had been abandoned, and so no warrant was required for law enforcement to obtain it.

These days, with services like gmail, we tend to keep our email on the servers for years, with no thought that it has been abandoned. Law enforcement is opposing reforms of this law because it would make their work more difficult. Doubtless it would, as does almost any civil liberty.

Earlier this month Zoe Lofgren introduced the Online Communications and Geolocation Protection act, amending ECPA. It would require a warrant to obtain cell phone location information. There is clearly some momentum for reform.
