Many corporations and consumers regularly come under cyber attack, and Google is no exception. We recently detected a cyber attack targeting our infrastructure and that of at least 20 other publicly listed companies. This incident was particularly notable for its high degree of sophistication. We believe Google Apps and related customer data were not affected by this incident. Please read more about our public response on the Official Google Blog.

This attack may understandably raise some questions, so we wanted to take this opportunity to share some additional information and assure you that Google is introducing additional security measures to help ensure the safety of your data.

This was not an assault on cloud computing. It was an attack on the technology infrastructure of major corporations in sectors as diverse as finance, technology, media, and chemical. The route the attackers used was malicious software used to infect personal computers. Any computer connected to the Internet can fall victim to such attacks. While some intellectual property on our corporate network was compromised, we believe our customer cloud-based data remains secure.

While any company can be subject to such an attack, those who use our cloud services benefit from our data security capabilities. At Google, we invest massive amounts of time and money in security. Nothing is more important to us. Our response to this attack shows that we are dedicated to protecting the businesses and users who have entrusted us with their sensitive email and document information. We are telling you this because we are committed to transparency, accountability, and maintaining your trust.
