Dasient Has Been Acquired by Twitter

The Dasient team is excited to announce that we have been acquired by Twitter! Effective immediately, we will be bringing our technology, tools, and team to the revenue engineering team at Twitter.

Since its inception, Dasient has been focused on solving web-scale security problems involving malware and other types of online abuse. In 2009, Dasient launched its web anti-malware platform, capable of scanning URLs and websites for the presence of harmful content. In 2010, Dasient launched the industry’s first anti-malvertising service to protect ad networks and publishers from the scourge of malicious ads. Over the last year, we have been very active in securing the ads and content of the some of the industry’s largest ad networks and web sites.

By joining Twitter, Dasient will be able to apply its technology and team to the world’s largest real-time information network. As part of this merger, Dasient is winding down its business and is no longer able to accept new customers.

We would like to thank our customers, partners, investors, and advisers for all of their support over the years, including Google Ventures, Radar Partners, Floodgate, and Benhamou Global Ventures.

We found that hashing IMEIs does not protect the privacy of users, even with the use of cryptographically secure hash functions. This result is due to the fundamental structure of IMEI numbers.

Debunking The Myths Of Mac And Mobile Malware

Writing malware, as with writing any other type of software, involves costs and benefits.  Like any software developer, malware authors want to reach as many users as they can, usually by creating a program that is easy and fast to deploy and can be written with minimum effort.  But with malware, these costs and benefits aren’t as obvious as many observers think.
