WEEKLY NEWSLETTER 25 - 30 OCTOBER 2021

Hello and Welcome,

COVID-19 News — Aspiration before Injection?

See the 13m53s YouTube video by Dr Moran | 17 Oct 2021.

He talks about "aspiration" before injection and the possible side effects if this is not done.

Aspiration means using the syringe plunger to withdraw a small amount of fluid before the actual injection of the COVID-19 Vaccine occurs.

The purpose is to make sure that the Vaccine does NOT go into a blood vessel but goes into the intramuscular area of the upper arm or Deltoid muscle.

He says the chance of hitting a blood vessel is probably less than 1%, but given the enormous number of COVID-19 vaccinations already given (6.5 Billion), that's an incredible number.

The problem is that intravenous injections may be the cause of blood clots with low platelets.

Something to ponder.

How a Google search could end up endangering a life

See the iTWire article by Sam Varghese | Monday 18 October 2021, at 10:28 am.

A Google search summary of measures to be carried out after a seizure left out the words "do not", resulting in instructions that could well kill a person.

Soft Linden, the director of information security at Linden Lab, a developer of digital entertainment, said in a tweet on Sunday that the summary of a page about what one should do after a seizure differed sharply from the original.

A search for the words, "had a seizure now what?" brought up a Google summary that said one should "Hold the person down or try to stop their movements. Put something in the person's mouth (this can cause tooth or jaw injuries)."

"Administer CPR or other mouth-to-mouth breathing during the seizure. Give the person food or water until they are alert again."

The advice was cited as coming from https://­healthcare.utah.edu­-> seizures and had the heading "What to Do During & After a Seizure | University of Utah Health." But the actual page said these were things that one should not do.

The Google search summary.

Another person posted a tweet showing that Google Home gave identical advice.

Linden's tweet gained sufficient traction to elicit a response from the University which said much later in the same thread: "We recently learned that a blog was displaying incorrect information in a question box generated by Google Search Engine."

The actual information on the site.

"We have taken steps to modify the content and re-index the page in hopes that the information in the answer box will be modified by the Google Search Engine."

iTWire has sought comment from Google.

Android Phones Susceptible to 'FluBot' Malware

See the Infopackets article by John Lister on October 15 2021, at 12:10 pm EDT.

Scammers have developed a new tactic to spread malware. It's a piece of evil genius with the emphasis strictly on the evil.

The scam involves a piece of malware that targets Android phones. It's dubbed FluBot, though that appears to be more a reference to how it's designed to spread quickly rather than having any connection to human illnesses.

FluBot first appeared earlier this year in a reasonably conventional form. It starts with unsolicited text messages claiming to be from a courier company that could not make a delivery. The culprits appear to have been taking advantage of people doing more online shopping following lockdown periods but now being more likely to be out of the house and miss deliveries.

The messages include a link to a page with a button that supposedly downloads a dedicated app to rearrange delivery and then track its progress. Instead, it's malware that appears mainly designed to try to access financial account logins. It also sends copies of the original text message to other phones, hence the virus-like spreading.

Security researchers highlighted the problem, and in the past few weeks, government agencies in countries including New Zealand ran awareness campaigns. That's when the scammers unleashed their new twist.

Bogus Warning

The download page no longer offers a tracking app but instead shows what appears to be a warning page with white text on a red background reading:

Your device is infected with the FluBot malware. Android has detected that your device has been infected. FluBot is Android spyware that aims to steal financial login and password data from your device. You must install an Android security update to remove FluBot.

The message finishes with a button marked "Install security update." (Source: threatpost.com)

Android At Risk

Of course, this is all a lie. The phone showing this message does not have FluBot... until that is, the user clicks the button, which, rather than remove the malware, starts installing it.

Although the messages have appeared on iPhones, FluBot seems only to be a risk to Android phones. The best advice is to never click on a link in a text message without first verifying it from the supposed sender. (Source: lifehacker.com)

Fun Facts:

Napoleon's Theorem

We'll construct Napoleon's Triangle, starting with an arbitrary triangle.

Draw a triangle, then construct an equilateral triangle on each of its sides.

Find the centroids of each equilateral triangle, i.e. join the three corners of the equilateral triangles to the midpoints of the opposite sides. See the dotted lines in the diagram below.

Notice that only two dotted lines are necessary to find the intersections, which are the centroids.

Napoleon's Theorem

Then, join these centroids to form a new triangle.

This will always be an equilateral triangle or Napoleon's Triangle. The proof is attributed to Napoléon Bonaparte.

Courtesy of Tim Brzezinski, here's an interactive page you can experiment with using the very popular mathematical software, Geogebra.

First, there's a slider on the diagram. This demonstrates the construction of the centroids and the actual new triangle.

Then you can move the points of the original triangle around and see what happens.

Here's a 2m31s YouTube video showing a straight-forward proof of Napoleon's Theorem.

Now, why didn't we have Geogebra in Geometry when we were in high school?

Oh, right, NO COMPUTERS! — Ed.
