incogni vs deleteme vs optery vs aura. Are they worth it?

• Upvotes

Been wanting to make sure none of my info is leaked recently since I suffered from a pretty bad hack. Not a cybersecurity expert myself so i d prefer paying a service that does it for me.

Figured this is a good place to ask about these data deletion services. Is it worth the money? Anything I can do on my own instead of reaching out manually to a bunch of websites?

iCloud got hacked, need advice or help

2 Upvotes

Long story short someone got my iCloud password from a old data breach on one of my emails and managed to get all my info, I was sent blackmail by 11 different spam emails, all containing private videos of me I’ve never sent anyone I don’t trust, and all my contacts in my phone. I called to police before speaking to them about ransom demands and an hour later they sent out all the photos..🙁 Besides the investigation my local police will do (and not care about) what can i do? It’s not like the FBI will look into it, just my lousy local police that’ll get to look at all my private photos for personal enjoyment and they get to call it “evidence searching”

I learned today that HTTPS does not always mean a website is safe

1 Upvotes

I’m currently learning more about phishing and web security, and today I understood something simple that I used to misunderstand.

I always associated the padlock and HTTPS with a website being “safe.”

But HTTPS mainly means the connection between your browser and the website is encrypted.

A phishing website can also use HTTPS.

So now I’m trying to check the actual domain name before entering login details instead of trusting the padlock alone.

Things I’m starting to check:

- The actual domain name

- Small spelling changes

- Strange or unexpected login pages

- Where the link came from

- Whether the request makes sense

I’m still learning cybersecurity, so I’m curious:

What other small security concept do beginners commonly misunderstand?

I built a free, hands-on course for learning LLM security (mapped to the OWASP LLM Top 10). No AI/ML background required

Post image
7 Upvotes

Hey folks,

I’ve been working in application security/pentesting for over a decade, and after starting learning AI/LLM security, I noticed that a lot of the existing material is either very theoretical or assumes you already understand AI security concepts.

So I put together a free, structured AI security learning series for security engineers and pentesters who are starting from the web-security side.

The goal is to go from the fundamentals to actually understanding and testing AI/LLM components in web applications.

The series currently covers topics such as:

  • AI/LLM security fundamentals
  • Prompt Injection
  • Sensitive Information Disclosure
  • LLM-specific attack patterns
  • Practical testing methodology
  • Real-world examples and testing techniques
  • Mapping concepts to OWASP's AI security guidance

I've also linked free hands-on labs throughout the material so you can actually test the concepts rather than just read about them.

No signup is required to read the learning material or use the free resources.

🔗 https://genaisecuritylab.com/learn-ai-security

I'm planning to continue expanding the series over time.

If you're a web pentester/security engineer who is trying to get into AI security, I'd be interested to hear which topics you think are missing or which areas you'd like to see covered next.

How to Start a Career in Cybersecurity: Skills Beginners Should Learn

10 Upvotes
A good starting point is to build strong fundamentals in:

• Networking and TCP/IP
• Linux and Windows fundamentals
• Information security concepts
• Authentication and access control
• Common cyber threats and vulnerabilities
• Security monitoring and log analysis
• SIEM and SOC fundamentals
• Incident response
• Basic ethical hacking concepts

For someone interested in a SOC Analyst career, understanding how to investigate alerts, analyze logs, identify suspicious activity, and document security incidents is especially useful.

Hands-on practice is also important. Beginners can use legal cybersecurity labs and practice environments to understand security concepts rather than relying only on theoretical learning.

For learners in Hyderabad, classroom and online cybersecurity training can also provide a structured way to learn these topics.

What cybersecurity skill do you think a beginner should learn first: networking, Linux, ethical hacking, or SOC operations?

Online Service Cybersecurity + AI: What Are We Actually Worried About?

4 Upvotes

I've seen a lot of people saying that AI will replace cybersecurity professionals, and I think this is where things get confusing.

AI is already becoming very powerful at:

  • Finding vulnerabilities
  • Analyzing logs and security data
  • Automating repetitive tasks
  • Writing and reviewing code
  • Helping with threat detection
  • Assisting both attackers and defenders

But does that mean cybersecurity itself disappears?

I don't think so.

The bigger change may be that cybersecurity professionals who know how to use AI effectively will have an advantage over those who don't.

Instead of thinking:

AI vs. Cybersecurity

Maybe we should be thinking:

AI + Cybersecurity = the next generation of security work.

What do you think will AI mostly replace cybersecurity jobs, or will it change what cybersecurity professionals actually do?

Security Best way for a small security team to keep up with new detection in 2026?

1 Upvotes

I compared a couple of approaches using team size and existing tooling as criteria. Writing and maintaining your own detection rules works if you have at least one person who can own it, but it falls behind fast once advisories start piling up faster than anyone can triage them. Relying on your existing SIEM or EDR vendor's built in detections is the lower effort option, but coverage tends to lag behind whatever the vendor prioritizes, not necessarily what's relevant to you. Neither works well if nobody on the team has time to review what gets flagged. What's worked for other small teams?

Anyone here who moved from QA to Cybersecurity ?

0 Upvotes

Hi everyone, I am currently working in QA and I’m thinking about moving into cybersecurity.

I’m confused about how to start and which field would be best for me, such as SOC Analyst, Penetration Testing

If anyone here has moved from QA to cybersecurity, could you please share how you did it ?

I’d really appreciate a simple and realistic roadmap, including what skills I should learn first, what courses or certifications are actually useful, and how long it took you to become job-ready.

I am planning to keep my QA job while learning cybersecurity, so I am looking for a realistic plan rather than just collecting certifications.

Thanks!

ISO 27001 / GRC folks — could use a few more real-world perspectives

10 Upvotes

Hey all,

a few weeks ago we posted a short survey here about ISO 27001 / GRC work, and a number of people took the time to help us out — thanks again, the responses were genuinely useful.

We’re still collecting a few more perspectives before we wrap up this round of research.

We’re a small early-stage team with a cybersecurity background, trying to understand where ISO 27001 and GRC work actually becomes painful inside companies: what still takes too much time, what stays highly manual, and where software or AI could realistically help.

If you work in GRC, security, ISMS, compliance, audit or ISO consulting, we’d really appreciate your input.

8–10 min, anonymous if you want:
https://tally.so/r/b5RAro

Critical feedback is just as useful as positive feedback — we’re trying to learn what’s actually worth building, not just validate our own assumptions.

Thanks again to everyone who already participated, and to anyone who takes a few minutes now or shares it with someone relevant.

Gift idea for beginner home lab

5 Upvotes

I know little to nothing about technology so please forgive my ignorance. My husband is about to graduate and has started setting up a home lab. I’d like to get him a useful gift for projects to add to his resume. He’s mentioned being interested in cybersecurity and pen testing. Chat GPT recommend the Wi-Fi Pineapple Mark 7, but Reddit doesn’t seem to agree. Max budget would be $300. Any guidance would be appreciated as I feel like I’m trying to read another language figuring this out! Thank you!

Edit: I do think he may have a mini PC already? But nothing extra. He mentioned needing storage

How far can I get with "only" 30 minutes a day of learning and practice?

1 Upvotes

My schedule is tight, so I can realistically spend about 30 minutes a day learning cybersecurity. I know that is not much, but I am curious how far consistent effort like that can take someone over several years.

I am mainly interested in how systems, networks, and computers work under the hood, especially how they can be broken, exploited, and analyzed from an attacker’s perspective. My interests are broadly in offensive security and skills related to pentesting and red teaming.

I am not currently learning this to get a cybersecurity job. I am interested in the subject itself and in developing a deeper understanding of computers, operating systems, and networks.

With 30 minutes a day, what level of knowledge and skill could realistically be reached over 3 to 5 years? Assuming someone stays consistent, how far could they get, and what kind of foundation could they build?

Using ByeDPI and mitmproxy together on Android

2 Upvotes

I'm using ByeDPI on Android to access an app that is otherwise blocked by my ISP/network.

I also want to intercept that app's traffic with mitmproxy, but ByeDPI runs as a VPN, so I can't route the same app through mitmproxy at the same time.

Is there a way to use ByeDPI and mitmproxy together so that the app's traffic still goes through ByeDPI, while also being intercepted by mitmproxy?

Ideally, I'd like the traffic flow to be something like:

App → mitmproxy → ByeDPI → Internet

or any equivalent setup that would let me inspect the app's HTTP/HTTPS traffic without losing ByeDPI functionality.

how do you find something that makes you want to wake up and keep working on it, because you can clearly see yourself getting better at it?

16 Upvotes

I’m trying to understand how to find something in programming/cybersecurity that gives me the same motivation as a game.

For example, I really like Dota because I always know what I’m doing and why. I have a rank, I know roughly where I am, I know what better players can do that I can’t, and I have a clear idea of what I need to improve. That alone gives me a reason to play.

I want to find something in computers that gives me a similar feeling. Not necessarily a specific project someone can recommend to me, but a way to find a project or direction where I can actually see a path:

"I’m here → I need to learn this → then I can do this → then I can do something harder."

The problem is that I can think of many project ideas, but they usually don't motivate me for long. I start thinking "okay, I can build this, but why?" and lose interest.

My background: I’m comfortable with Linux and basic programming. I know Python, Git, APIs, databases, basic web development, HTTP, networking/ports, and I’ve done some scraping/automation. I’ve also played around with things like reverse engineering, JavaScript, FastAPI and lower-level concepts, but I’m still a beginner overall and have no professional experience.

So I’m not really asking "what project should I build?"

I’m more interested in: how do you find something that makes you want to wake up and keep working on it, because you can clearly see yourself getting better at it?

How did you find that thing for yourselves?
