Google has posted to their blog information about a targeted attack against the personal Gmail accounts of US government officials, political activists, military personnel and journalists.
Mila from the Contagio blog provides much more detailed information about the attacks. The messages appear to be handcrafted and spoofed to seem to be from governmental colleagues of many of the victims.
Normally attachments in Gmail appear with a paper clip and links to view or download the item. The attackers created HTML that used fake attachment links that actually lead to a phishing page designed to look identical to the Gmail login page.
Mila wrote about these attacks in February, but the big news is Google sharing this information publicly. Most organizations prefer to keep security problems to themselves and maintain the illusion that their services are perfectly secure.
While this attack is not specifically a problem with Gmail, it is a widespread security weakness in many cloud services. Google sharing information with the public about how these attacks are executed helps all of us learn from these situations and build better systems.
Google gives some good advice in their post, although it seems strange that they feel the need to push Google Chrome as a solution to all security problems...
How should we respond to this news? We should take a moment to remind our users about best practices when using web-enabled technologies.
