11 bugs. One target. $40,000. Critical infra leak. ATO. SSRF x2. OAuth bypass. DoS. Sometimes one target is all you need. #BugBounty

Folks have given the right answer already. I would like to add one more thing we can’t deny traffic using SG but only using NACL so for explicit deny like blocking traffic from specific ip etc NACL should be used. Anything not specified in SG is implicitly denied by default . To keep it clear if we want to allow all traffic from a subnet except one ip add allow rule in SG to receive traffic from the subnet and in NACL add a deny for that single ip belonging to the same subnet

Are Security Groups in AWS EC2 stateful or stateless ? and how it works ?

@devops_nk Thanks for sharing

Prompt: "Create a clean AWS architecture diagram with official AWS icons in 16:9 format. Flow: Users → Route53 → CloudFront → AWS WAF → Bot Mitigator → ALB inside VPC → Amazon EKS Cluster → Kubernetes Ingress → Spring Boot microservices (User, Order, Payment) → multiple Pods. Add AWS managed services below: RDS, ElastiCache Redis, S3, SQS, Secrets Manager. Add Observability section with CloudWatch, CloudTrail, IAM. Use enterprise-style arrows, dotted sections, white background, and modern cloud architecture design." Many of you asked for it, so here is the prompt. Happy learning.

@devops_nk Amazing. May I know the prompt u used

Created by ChatGPT Images 2.0, BTW I used to spend hours to create it on draw .io

@SumitM_X 401 bcz creds are not valid for missing privileges 403 is ideal

Wrong credentials... What should be sent ? 401 or 403 ?

@GamewithDave Road rash

For anyone who used a computer between 1990 & 2005… what’s the one game you still think about?

@WorshipDhoni Calm before the storm 🔥

@WorshipDhoni Yes he is our lucky charm

Miller's wicket was the turning point and then Stubbs wicket. Thank you Overton 🙏🙏 #CSKvsDC

@msblr_tw True, famines did exist in the past. But my point is we’ve moved from uncertain access to constant surplus cheap, calorie-dense food everywhere and far less movement.Good, nutritious food is still available, but people often don’t choose it

@VenkatDev789 I also oppose excesses and chemicals in food, but there were deadly famines all over India on almost an annual basis. Even a King couldn't get his dinner delivered within 10 mins as is the case today. This was the case for many centuries.

Not a big fan of AI edits, but this is so wholesome to watch 🫶 #Cute

@msblr_tw people weren’t starving all the time, but they also weren’t surrounded by cheap, high-calorie food everywhere. Now it’s everywhere, and we move way less, that’s the real difference.

@VenkatDev789 Yes. Starvation was more prevalent.

@pulkit_mittal_ The api should reject delete request if there is no filter. Every delete should have a where clause

Question time: A junior engineer ran DELETE API but forgot to put filters. Production data is wiped in seconds. What system design decisions would’ve saved you here?

@SumitM_X I would go with SQS (uses https) , let AWS manage most of the responsibilities like server, avlability, storage, security etc

One microservice needs to send a message to another microservice asynchronously. How would you handle this in Java, and what protocols would you use?

@uday_devops Pending, running, stopping, stopped shutting down, terminated.

Interviewer: What are the lifecycle states of an EC2 instance?

@amrelsagaei Waiting. Thanks in advance mate

STAY TUNED....

@ajay_2512x Thanks for sharing, very useful

Just tried System Design Lab by Sumit Suman ,this is seriously impressive A fully interactive platform (no signup!) covering everything from OOP & design patterns to distributed systems, with simulations, mock interviews, and even a "System Architect Survival" game based on real outages. Hands-on > passive learning. This is how system design should be taught. systemdesignlab.netlify.app Great work building something genuinely useful for the community 🚀

@zack0x01_ Video explaining how to make better use of AI for bug bounty would be super useful . Thanks in advance

I ran ma AI hack bot before i sleep , and it found 2 RCE 😭 I would never have found that manually ✨ #bugbounty

@SumitM_X It’s the same encrypted media pipeline but just with a small flag (metadata) like viewOnce=true. The app shows it once, avoids storing it, and deletes it immediately after. So backend sets the rule, client side enforces it

As a developer, Have you ever thought : How is "View Once" photo implemented in WhatsApp? When you send a view-once image… How Is the image different from normal media?
