MyDFIR

I run a community showing you how to build practical hands-on skills to become a Cybersecurity SOC analyst. 👇

[MyDFIR @MyDFIR]

Enjoy! I am excited to see how y’all transform this into something even better. These are just the building blocks, it is up to you and your creativity 💙

One fake invite can end in a compromised mailbox, a stolen OTP, or a remote tool running as SYSTEM. And your team might not connect those dots until the foothold is already there.

This is where a sandbox earns its keep. When a suspicious link hits your queue during triage, you can detonate it somewhere safe instead of guessing. Within seconds you can see whether it is a fake invite, a credential form, an OTP prompt, or a remote tool quietly downloading itself. And as it runs, you are watching the actual behavior. The network calls, where the credentials get posted, what files drop, and whether anything reaches out for remote access.

@anyrun_app researchers tracked a large campaign going after organizations with fake event invitations.

Here is the remote-tool path, detonated in the sandbox.

🔸 User clicks the invite link
🔸 A Cloudflare CAPTCHA loads
🔸 Page auto-downloads a remote management installer, pulled straight from the lure domain
🔸 In one version there is not even a button. The download just starts on its own.
🔸 The installer runs through msiexec
🔸 The remote client installs as a Windows service running as SYSTEM
🔸 That service beacons out to a relay the attacker controls

That last step allows the attacker to have hands on keyboard access through a signed, legitimate allowlisted tool.

Most of the https://t.co/TydYfoF5wq submissions for this campaign came out of the United States. And the industries getting hit are the ones you would expect:

🔸 Education
🔸 Banking
🔸 Government
🔸 Technology
🔸 Healthcare

Look at what those have in common. Email, identity, and remote administration are just part of the normal workday. A remote management tool showing up on a machine in a hospital IT shop or a university help desk does not look strange.

As of late April, around 160 suspicious links were analyzed and around 80 phishing domains were observed. Most sat on .de TLDs, which is a little odd for a campaign aimed at US orgs and worth watching for on its own. A lot of them were built from the same phish kit and some sessions even had instructions left in for the operator on how to edit the page.

That reused infrastructure is good news for us. When attackers mass produce lure sites from one kit, they leave similar fingerprints everywhere.

Here is what to hunt for and be sure to baseline your environment first.
🔸 An RMM (Remote Monitoring and Management) client install (ScreenConnect, ConnectWise, ITarian, Datto, LogMeIn, etc.)
🔸 An RMM service reaching out to a relay you do not recognize as your own
🔸POST requests to /processmail.php, /process.php, /pass.php, /mlog.php (likely noisy which is why baseline is important here)

A quick win is to find every RMM in your environment and note the ones that belong. After that, any new RMM install should get flagged for a closer look.

I broke down a #socanalyst job posting and showed you exactly what they expect + how you can start learning each skill so you’re actually prepared when applying.

If you’ve ever looked at a #soc posting and thought:
“Where do I even start learning all of this?”

This video is for you.

@Odus_olaa Proud of you for taking action and completing this!! Keep it up and I look forward to seeing more 🙌

[MyDFIR @MyDFIR]

@Oriaonm Always happy to help 🙌

Can you spot the suspicious activity?

This is a snippet of the MFT (Master File Table) artifact data from a forensic investigation scenario. Been building this out as part of the DFIR course for the MYDFIR Forge. Total of 14 modules with a mix of Windows, Linux, network, memory and cloud (Azure) forensics including a capstone investigation. This is a big course and will include a lot of theory + labs!

Can't wait to release it.

I'll be providing more details in the free SOC community as we get closer to the release!

I kept getting messages from beginners saying they wanted to become SOC analysts but not sure where to start so I built a free community that’ll give them a good starting point called The MYDFIR SOC Community:

Inside has 4 structured modules (fundamentals → portfolio projects)

No paywall. No catch.

@RussianPanda9xx 😭😭 might as well be at this point!!!

[MyDFIR @MyDFIR]

While building a lab for the community, I ran into something weird.

Setup:
Attacker PC: Windows 10 22H2 (UTC):

1) Created a timestomped LNK file (Year 2028)
2) Zipped it with password-protected 7-Zip

Target PC: Windows 11 24H2 (PST)
1) Extracted the file
2) Examined the MFT
- SI records 2028 && FN records 2026 (so far so good)
3) Shift + Right-Click LNK > Run as Administrator

The weird part:
After running it as Administrator, the FN timestamp, what use to be 2026 is now blank which if I am not mistaken would indicate it is the same time as SI.

Has anyone else seen this behavior? Not sure if this is a known thing or something new with 24H2.

Anyways, another reason to be sure to correlate with other artifacts!
