Diplomats Reportedly Zapped with Microwaves

Mysterious neurological symptoms experienced by U.S. diplomats in China and Cuba appear to be caused by directed microwave energy, according to a new report by the National Academies of Sciences (NAS) obtained by The Hill...

A source familiar with the symptoms told NBC News, which was the first to report on the findings from NAS, that the CIA had determined Russian operatives who had worked on microwave weapons were in the same cities as CIA agents at the time they began experiencing the neurological symptoms.

U.S. diplomats in Cuba began experiencing the symptoms in late 2016, reporting they were hearing strange sounds and experiencing odd physical sensations before becoming sick. Some of those symptoms disappeared, while others lingered.

Cuba has denied any knowledge of the illnesses. more

Ultrasound Talk Gives a Whole New Meaning to Defcon

Researchers have long known that commercial speakers are also physically able to emit frequencies outside of audible range for humans. At the Defcon security conference in Las Vegas on Sunday, one researcher is warning that this capability has the potential to be weaponized...

Matt Wixey, cybersecurity research lead at the technology consulting firm PWC UK, says that it’s surprisingly easy to write custom malware that can induce all sorts of embedded speakers to emit inaudible frequencies at high intensity, or blast out audible sounds at high volume.

Those aural barrages can potentially harm human hearing, cause tinnitus, or even possibly have psychological effects.

And while it is still unclear whether acoustic weapons played a role in the attack on United States diplomats in Cuba, there are certainly other devices that intentionally use loud or intense acoustic emanations as a deterrent weapon... more

Mystery ‘Sonic Attack’ on U.S. Diplomats in Cuba Was Really Crickets

Fake news? You decide.
Diplomatic officials may have been targeted with an unknown weapon in Havana. But a recording of one “sonic attack” actually is the singing of a very loud cricket, a new analysis concludes.

In November 2016, American diplomats in Cuba complained of persistent, high-pitched sounds followed by a range of symptoms, including headaches, nausea and hearing loss.
Exams of nearly two dozen of them eventually revealed signs of concussions or other brain injuries, and speculation about the cause turned to weapons that blast sound or microwaves...

On Friday, two scientists presented evidence that those sounds were not so mysterious after all.

They were made by crickets, the researchers concluded. more

Fact: Buddy Holly released chirping crickets in 1957, and died about two years later. Just coincidence? You decide.

"New" Theory on the Cuba / China Sonic Headaches

The mystery illness afflicting American diplomats in Cuba and China could be a side effect of bugging or surveillance rather than a sonic weapon attack, according to a US researcher.

Dr Beatrice Golomb, professor of medicine at the University of California San Diego, said the reported symptoms strongly matched the known effects of radio frequency and microwave radiation.

Surveillance is my lead hypothesis, as opposed to something like attacks or weaponry,” said Golomb, whose research will be published in the journal Neural Computation on September 15. more

Cuba's Sonic Attacks - Possibly a Side-Effect of Spying

Its surveillance tools may have transmitted ultrasonic sounds by mistake...

Remember those 'sonic attacks' against the American and Canadian embassies last summer, making staff queasy and raising all kinds of questions as to what happened? There might have an answer. University of Michigan researchers have theorized that the incidents were really the result of ultrasonic signals from poorly functioning surveillance equipment. While individual ultrasonic signals can't harm people outside of extreme circumstances, multiple signals can clash with each other and produce a sound that's just low enough to be audible.

The scientists tested their hypothesis by replicating the "chirping" from an AP video using two ultrasonic emitters that combined tones, one at 25kHz and another at 180Hz. That produced a similar-sounding 7kHz frequency with ripples of sound at an even 180Hz spacing. The team even built a device that would simulate eavesdropping by playing a song instead of the 180Hz tone. more

Cuba - Concussion-like Symptoms Found in US Diplomats - Updates

Members of the US diplomatic community in Havana began visiting the embassy’s medical unit in late December 2016 with symptoms, such as headache and ear pain, that they said began after they encountered strange sounds or sensations...

In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba, associated with reports of directional audible and/or sensory phenomena of unclear origin. These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma...
