Every year, close to 600,000 sites are hacked. Given the scale of the problem, notifying users to prevent harm and webmasters so they can clean up their sites is critical to combat hacking. This post looks at the effectiveness of the current warning strategies used by Google and their long-term impact.
As an experiment we dropped nearly 300 USB sticks on the UIUC campus to assess if USB drop attacks work and see if concerns about USB security were justified. We found out that at least 48% of the drive were plugged. This blog post summarizes how we ran the study, highlights the key findings, looks at what motivates people to plug in USB sticks, and discusses possible mitigations to improve USB security.
This post provides an in-depth analysis of the lessons we learned while protecting Gmail users and their inboxes. We felt it was about time to share the key lessons we learned the hard way while protecting Gmail for over a decade, so everyone involved in building an online product can benefit from them. To that effect, with the help of various Gmail safety leaders and long-time engineers, I distilled these lessons into a 25-minute talk for Enigma called “Lessons learned while protecting Gmail”. While such a short talk is great at providing an overview, it forces you to leave out details that provide deeper insights. This blog is, therefore, meant to fill this gap by sharing a more complete explanation for the lessons that need one and it complements my talk on the subject.

Big data weaponization and malware-based espionage are usually associated with governments; however, they don’t own a monopoly on such activities. Also, online poker uses big data to profile user behavior. Players search for fish (bad players) and they use malware to spy on and rip off infected players at the (online) poker table. This blog post is a brief tour of some of the darkest aspects of online poker.
This post summarizes which equipement the FBI use to seize the content of servers and laptops despite many of them use full disk encryption and which defenses exist.
This post looks at how an attacker can intercept and read emails sent from one email provider to another by performing a DNS MX record hijacking attack. While our research on the state of email delivery security indicates that this attack is less pervasive than the TLS downgrade attack discussed in a previous post, it is equally effective at defeating email in-transit encryption. This post explains how this attack works, how it can be mitigated and to what extent it also affects the security of a website.
Follow these ten easy steps to improve your online security and privacy quickly.
Over the last two years, the number of encrypted emails received by Gmail has almost doubled, as I reported earlier on the Google security blog. This very encouraging trend is sadly accompanied with an increase of SMTP TLS downgrade attacks, which prevent encryption of emails in transit as discussed in our research paper on the state of email transport security. This blog post explains how such an attack is performed and why there is no simple “patch” for it.
Phishing is a social-engineering attack where the attacker entice his victims to give-up their credentials for a given website by impersonating it. Believe it or not phishing campaigns are well organized and follow a very strict playbook. This post aim at shedding some light on how phishing campaign works under the hood, showcase which infrastructure phishers use to steal users credentials and provide advice on how to defend against it.
