How to find a malicious TCP program using netstat
fr flag

I am trying to do a homework for a lab but have a quick question.

How do I find a malicious TCP service that is still running and the adversary has achieved persistence by creating a systemd service?

I think I have to use netstat to find the name of the malicious TCP service, but what command should I use to find that service?

Thank You

Is there still a need for the web applications/API to use HTTPS if the proxy server is already using it in microservices architecture?
it flag

If my proxy server already is using HTTPS/SSL, is there still any sense for my other applications to implement it too?

I'm trying out microservices architecture through Docker/Kubernetes, and I am using Nginx as a reverse proxy for multiple applications/services. Only the proxy server has its ports exposed.

And in case it is still big deal to implement it, how to produce these kind of certificates f ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
