Cyber Shield Scam
🚨 The “Cyber Shield” Scam: Debunking David Ruble’s Fake Jammer
The TI community is under attack — not just by weaponized tech, but by grifters exploiting confusion and desperation. One of the most damaging today is the so-called “Cyber Shield” device sold by David Ruble, who claims it jams targeting signals by heterodyning RF down into the brainwave range (5–40 Hz).
Let’s be clear:
❗ The device does not jam anything.
❗ The science Ruble claims to use is impossible with the hardware he’s using.
❗ And if his device does transmit anything, it may be illegal under federal law.
🔍 What Ruble Claims
David Ruble claims his device:
- Uses multiple ADF4351 RF synthesizers this was figured out by looking at pictures of his device
- Is controlled by a microcontroller
- “Heterodynes” signals down to affect brainwave regions
- Doesn’t need to “find the frequency” — because it supposedly interferes at a lower harmonic layer
When I asked him directly:
“How can you jam a signal if you never found the frequency attacking the person?”
He responded:
“It heterodynes down to the brainwave region — it doesn’t need to find the frequency.”
🔬 That response triggered my skepticism — so I built out the setup myself to test it.
⚙️ I Tried to Recreate It — It Doesn’t Work
I attempted to replicate Ruble’s setup, using:
- The same ADF4351 modules
- A similar microcontroller
- Custom firmware to mimic his “jamming pattern”
💥 Result:
- The ADF4351 cannot generate or interact with anything close to 5–40 Hz.
- It operates in the 35 MHz to 4.4 GHz range — millions of times above brainwave frequencies.
- It has a resolution bandwidth (RBW) of 300 kHz, which means it can’t generate tightly spaced waveforms anywhere near the necessary Hz resolution.
To interact with brainwave bands, you’d need:
- Precision signal generation in the 5–40 Hz range
- Controlled phase and amplitude modulation
- Hardware that costs over $5,000+
ADF4351 chips? Completely incapable of it.
⚖️ Legal Reality: This Might Be a Felony
Let’s entertain the idea that Ruble’s device does output random RF noise.
If it does, even accidentally, and it emits into the public RF spectrum without FCC authorization:
🚨 That makes it a radio frequency jammer — and that is a felony in the United States.
According to the FCC:
“The use of a jammer… is a violation of federal law… punishable by fines of up to $112,500 per act and criminal penalties including imprisonment.”
So let’s get this straight:
- If the device does nothing: It’s a scam
- If the device transmits noise: It’s illegal
Either way? You’re paying for trouble — not protection.
👩💻 False Testimonials & Social Engineering
Ruble’s scheme is also propped up by a group of women making unverifiable testimonials:
- Claiming “miraculous results”
- Offering emotional stories with no scientific backing
- Often repeating Ruble’s exact pseudoscientific phrases
No spectrum analysis.
No control experiments.
No data. Just word-of-mouth manipulation.
It’s emotional bait — not evidence.
❌ Jamming What, Exactly?
Let’s revisit the most basic flaw in Ruble’s logic:
“How can you jam something… if you never even found what frequency is attacking people?”
Ruble never provides a measurement, never shows:
- A spectrum trace
- A near-field EM probe readout
- A directional source or signal fingerprint
Without identifying the signal:
- You can’t build a countermeasure
- You can’t create interference
- You can’t tailor a waveform
It’s RF engineering 101.
And yet Ruble skips this step entirely — because he knows his device can’t detect anything real to begin with.
🧠 Why This Scam Hurts the TI Community
Ruble’s fake science and scammy product:
- Steals thousands of dollars from vulnerable people
- Gives false hope that blocks real solutions
- Discredits legitimate research and testing
- Could even get buyers in legal trouble
Scams like this slow down our fight for real answers — and give ammo to skeptics and disinfo agents looking to label TIs as delusional.
🧾 Final Thoughts: Stay Sharp
Let’s call this what it is:
❌ A toy pretending to be a defense tool.
❌ A theory pretending to be science.
❌ A fraud, hiding behind tech buzzwords.
We don’t need more noise. We need repeatable data, validated tools, and truth.
