SPF, DKIM, DMARC and BIMI for Email Security

Phishing attacks have been increasing rapidly year on year, and surged as a result of COVID-19. Research shows that 96% of phishing attacks are sent by email. A common technique used in these attacks is to impersonate well known or trusted brands to entice users to open links and attachments. One way to achieve this is to “spoof” the email address that is shown to users in their email client.

Preventing exploitation of the Follina vulnerability in MSDT

This article provides a synopsis of the Follina exploit and simple steps you can take to mitigate this severe remote code execution vulnerability within Microsoft Support Diagnostic Tool (MSDT). This vulnerability is triggered via common Windows applications such as Microsoft Word and is being actively exploited by known hacking groups.

Application Security 101 - HTTP headers

This article is the first in a series that will discuss some of the most common issues with HTTP security headers, which are often relatively easy to implement and can have a significant impact on the overall security posture of your application. We’ve previously talked about the proactive and reactive styles of application development and security testing. In this article, we discuss HTTP headers which are a common misconfiguration.

New Exchange RCE vulnerability actively exploited

Exchange admins now have another exploit to deal with despite still reeling from a number of high profile attacks this year including ProxyLogon and ProxyShell. A new high severity Remote Code Execution (RCE) exploit for on-premise Exchange Servers has been published and is being actively exploited in the wild.

How effective is secure code review for discovering vulnerabilities?

We’ve recently discussed application security and the trend we’re seeing in which companies are increasingly implementing security early on in the Software Development Life Cycle (SDLC). In our blog post exploring the impact of adopting application security, we described a common scenario involving assessing an application that was ready for release. Through the assessment, critical vulnerabilities were identified, such as an SQL injection, close to the go-live deadline.

Application Security (AppSec)

There is a movement in the IT security world that is gaining traction, and it is based around the implementation of security within applications from the beginning. You may have heard buzzwords like “AppSec”, “DevSecOps” and “Shift Left”, but what do they actually mean? What does it take to “Shift Left” when developing a secure application? You can read about dealing with dependencies in our blog post.

Enhancing Security in your Software Development LifeCycle - Dealing with Dependencies

The adoption of agile practices has resulted in the emergence of shift-lift testing, where testing is performed much earlier in the Software Development LifeCycle (SDLC). Traditional waterfall models performed testing to the right of, or following, development. The benefits of testing earlier and more often cannot be underestimated. However, where does this leave security and security testing?

Exchange Server Emergency Mitigation Service

It has been a tough few months for Microsoft. After the SolarWinds/NOBELLIUM attacks, Microsoft Exchange customers were afflicted with a slew of vulnerabilities. In March 2021, the ProxyLogon vulnerability emerged, followed by an exploit that surfaced in April 2021 called NSA Meeting. In August 2021, Orange Tsai released a series of new vulnerabilities called ProxyOracle and ProxyShell, followed by the discovery of another Proxy flaw, dubbed ProxyToken.
