Microsoft Exchange On-Prem Zero-Day Vulnerabilities Exploited in the Wild

On Thursday, September 29th, 2022, GTSC–a Vietnam-based cybersecurity company–published a blog detailing intrusion they investigated that chained together two exploits for Microsoft Exchange zero-day vulnerabilities to achieve remote code execution (RCE). Technical details around how to exploit these vulnerabilities were not provided.

What is FedRAMP?

That’s a good question if you’ve been curious about what it is and if it applies to you. For example, do you have a cloud product that the US Government would gain benefit from using? Are you being asked to seek a security approval or an “ATO” by your customer? We’ll go through the basics of FedRAMP in this article to help you understand where you stand in that process. FedRAMP is a government-wide program.

Reducing the Impact of Ransomware Attacks (Yes, It's Possible)

Ransomware is the fast-growing category of cybercrime. It’s estimated that over 4,000 ransomware attacks occur daily. Given the sheer volume of these attacks and the deep attack surface connections between organizations and their vendors, there’s a high likelihood that some of your employee credentials have already been compromised in a ransomware attack, which means the keys to your corporate network could currently be published on a ransomware gang’s data leak site.

Strengthen Your SaaS Security with SaaS Ops

Many organizations have multi-cloud setups, with the average corporation employing services from at least five cloud providers. Compatibility problems, contract breaches, non-secured APIs, and misconfigurations are among the security hazards cloud computing brings, which is popular. SaaS configurations are an attractive target for cybercriminals because they store a large amount of sensitive data, such as payment card details and personal information.

Detecting the Manjusaka C2 framework

Security practitioners may know about common command-and-control (C2) frameworks, such as Cobalt Strike and Sliver, but fewer have likely heard of the so-called Chinese sibling framework “Manjusaka” (described by Talos in an excellent writeup). Like other C2 frameworks, we studied the Manjusaka implant/server network communications in our lab environment, and here we document some of the detection methods available. We have also open-sourced the content we describe.

Why You Should Avoid Public WiFi

The ability of a cybercriminal to place themselves between you and the connection point poses the biggest security vulnerability to public WiFi. You unknowingly communicate with the cybercriminal, who then collects and passes your information to the hotspot, rather than you connecting to the hotspot directly. While there are ways to stay protected on public WiFi, it is still advisable to avoid using it.

Three Reasons Why You Should Quantify Third-Party Cyber Risk

The spotlight on cyber risk quantification (CRQ) has raised its status to the top of the hypercycle, but with fame comes scrutiny and criticism. Security analysts and practitioners debate the validity of each model framework, along with the data used when modeling cyber risk. Despite this debate, there is a unifying consensus that knowing the possible range of the financial impact of a cyber event is far more optimal than flying blind.

IT admin admits sabotaging ex-employer's network in bid for higher salary

A 40-year-old man could face up to 10 years in prison, after admitting in a US District Court to sabotaging his former employer’s computer systems. Casey K Umetsu, of Honolulu, Hawaii, has pleaded guilty to charges that he deliberately misdirected a financial company’s email traffic and prevented customers from reaching its website in a failed attempt to convince the firm to rehire him at a greater salary.
