@bjjtaro 🤣 That’s pressure

4/4 Key takeaway: In cloud ecosystems, deletion is often a process, not a single event. Digital evidence can exist longer than most people realize.

[David D @DavidDerigiotis]

1/4 Deleted doesn’t always mean gone.

When footage is recorded on Nest devices, it may exist in multiple places:

-Cloud storage
-Backup systems
-Replicated servers
-Log data and metadata systems

The FBI’s publication of videos from Nancy Guthrie’s Google Nest doorbell camera has reinvigorated questions that have dogged big tech companies as they have become a larger part of people’s daily lives. https://t.co/HiheO9lpzr

3/4 With a valid legal process (warrant/subpoena), Google can search backend storage, backups, and system logs to recover remaining data fragments or copies.

Thank you for the important conversation. AI using biometrics + kids = a problem we can’t ignore. Hear why:

@MikeRogersForMI did I just walk past you at DTW?

[WXYZ Detroit @wxyzdetroit]

A phishing email targeting Livonia Public Schools students promised $300 a week for remote, part-time work, but scammers were actually after sensitive personal and banking information.

[TikTok USDS Joint Venture @tiktokusdsjv]

We've made significant progress in recovering our U.S. infrastructure with our U.S. data center partner. However, the U.S. user experience may still have some technical issues, including when posting new content. We're committed to bringing TikTok back to its full capacity as soon as possible. We'll continue to provide updates. Thanks for your patience.

[David D @DavidDerigiotis]

From personal experience, @tiktok_us seems to be having glitches & issues with content reach, visibility, & properly tracking comments & likes. Some are claiming censorship while the company stated an issue at a data center. I will be joining @rooprajfox2 on @FOX2News to discuss

[FOX 2 Detroit @FOX2News]

Victims are being preyed on and instead of sending gift cards - are now being directed to pay scammers using Bitcoin kiosks. https://t.co/3aQttY3MzL

1/5: Heads up on the recent Instagram scare: Millions got unsolicited password reset emails since Jan 8. A Cybersecurity firm spotted a dataset with info from ~17.5M accounts (usernames, emails, phones, locations) on the dark web. But is it a breach? Thread 👇

[David D @DavidDerigiotis]

4/5: Tips to stay safe: Enable app-based 2FA (skip SMS), check login activity in the app, use unique passwords everywhere, & verify emails directly on Instagram. If you got a reset email, change your PW just in case, but NOT through links in any unsolicited password reset email

It has taken me far too long, but I have finally finished reading the Bible cover to cover. The Bible is made up of 66 books with 40 different human writers (2 Timothy 3:16) over a period of ~1,500 years.

6/6 Stay safe: Hang up on urgent calls demanding crypto payments. Report to FBI's https://t.co/8TQrfLlksm and/or local law enforcement. Share this thread to protect others! This will not be going away any time soon.

[David D @DavidDerigiotis]

1/6 Alert: The FBI reports a staggering $333M in losses from Bitcoin ATM scams in 2025 alone! That's a massive increase, with criminals targeting vulnerable people. https://t.co/T130c4GmOj Thread ahead to learn the tactics & how these scams work. #CryptoScams #FBIWarning

[David D @DavidDerigiotis]

5/6 Victim enters amount & scans/enters wallet address. 6. Insert cash bills. 7. Review fees/rate & confirm. 8. BTC sends to wallet (10-30 min confirmation). Receipt provided. Legitimate organizations/Law enforcement will NEVER demand payment via Bitcoin ATM!
