Firefox users in the US will soon have DNS-over-HTTPS (DoH) enabled by default. Mozilla is in the process of rolling out the privacy- and security-focused feature after an intensive period of testing.

DoH is an option for anyone outside of the US, but it will have to be manually enabled. Once enabled, DNS lookups are routed through Cloudflare or NextDNS using an encrypted HTTPS connection, hiding it from third parties such as your ISP.

Digital criminals are increasingly pivoting to the network after initially attacking an endpoint or publicly accessible cloud. Indeed, a network foothold enables attackers to move laterally to more valuable cloud workloads. They can then steal their target organization’s sensitive information and monetize it in whatever way they deem fit.

Many of us are fighting back against the threat of lateral movement by augmenting our visibility over the network. However, we’re constantly running into challenges in the cloud. When using AWS Virtual Private Cloud (VPC) or Azure Virtual Networks (VNets) to detect threats in network traffic, for instance, we’re missing packets’ application-level context. We thus can’t detect the malicious activity that hides within them. In this post, we will discuss why achieving visibility into the cloud continues to pose a challenge. We’ll then explore how we can gain the requisite level of visibility in the cloud.

At the root of most data breaches is a compromised account, but these can be very hard to identify, often coming to light only after they've been used to steal data.

Email security specialist GreatHorn is launching a biometric solution that effectively identifies compromised accounts and blocks takeover attempts by validating users using their unique typing patterns.

As more services move to the cloud, enterprises are exposed to increased risks from data breaches, and around 40 percent of organizations have suffered from Office 365 account takeovers.

According to Microsoft's Q3 2019 earnings call, there are more than 180 million monthly users on Office 365, which means there's a big attack surface out there for cybercriminals. That's why threat detection and response specialist Vectra AI has announced a new tool to help businesses protect themselves.
