The future of cybersecurity: Your body as a hacker-proof network
Could a 'body area network' be the key to keeping medical devices safe or transferring data between individuals?
Modern medicine is making use of the internet with more devices having internet connectivity. Insulin pumps, pacemakers, and more implantable devices are being fitted with wireless internet connectivity that allows doctors to monitor your health remotely.
The issue with being connected to the internet is that the devices can be hacked. Already proof of concept attacks has illustrated the risk exists. Fortunately, there have been no attacks so far but cybercriminals have demonstrated a lack of morality and tampering with these devices will no doubt happen. In the past, they have extorted hospitals putting patients at risk.
The wireless technology used to share data can be read many feet away. Recently implantable defibrillators were given a severity rating of 9.3 out of 10 for a flaw that allowed them to be hacked 20 feet away by the Department of Homeland security.
Scary stuff but new research using the human body as the signal carrier restricts the signal to a few centimeters outside the patient. Researchers at Purdue University have created Electro-Quasistatic Human Body Communication (EQS-HBC) which uses low-frequency, carrier-less broadband transmission.

The dead will take over Facebook in the next 50 years
Analysis suggests that the deceased will soon outnumber the living on the network.
and I thought it was me the reason no one responded to my posts. :-)
A time is coming in which you may see more memorial accounts on Facebook than active users, with academics estimating that accounts belonging to the deceased will outnumber the living within 50 years.

Ransomware: The cost of rescuing your files is going up as attackers get more sophisticated
The average ransom demand is up to almost $13,000, compared with $6,700 just a few months ago.
The sharp increase in ransom payments is linked to the emergence of more expensive and more hands-on forms of ransomware like Ryuk, Bitpaymer and Dharma.
While ransomware attacks of the past generally relied on spamming out large numbers of phishing emails in the hope of getting a few hits, now cyber criminal groups are taking a more focused approach with attacks.
They are now attacking computers directly across the internet. The new forms of ransomware rely on more direct attacks on computers. They are exploiting security holes in remote desktop protocols (RDPs) to gain access to systems and once in they are attempting to infect and encrypt as many computers as possible on a network. That is why it is so important to install updates on your system and not to use outdated operating systems that are no longer supported by manufacturers, see prior post below.
https://dforceatl.blogspot.com/2019/04/windows-updates-problems-and-new.html
Office 365 users are targets of phishing attempts attempting to steal their credentials. It is easy to copy the underlying source code of a website, Office 365 portal for example and then publish it to create a fake website that looks like the genuine site (you must pay attention to URL). The target will receive an email allegedly from Microsoft threatening to close the account unless action is taken. The link to the phony site will then ask for your email and password. If the info is supplied, the attacker will then take charge of your account, encrypting OneDrive, Sharepoint and using the compromised email to send phony financial documents and other attachments which will appear to come from a trusted source by the recipients. Be careful.
If you are a victim of ransomware, the attackers can command ransom payments of six figure sums – which attackers demand in cryptocurrencies like Bitcoin.
While the authorities generally don't recommend that victims of ransomware attacks pay the ransom demand – it funds criminal activity and there is no guarantee it will work anyway – in some cases, organizations feel as if they don't have a choice.
It was last month that I wrote about Jackson County, Georgia paying $400,000 to criminals that had infected it's systems with ransomware.

Windows Updates - problems and new Feature Release 1903 due soon.
Since Windows as a Service (SaaS) became the norm with the introduction of Windows 10, Microsoft has been making changes to the way it rolls out updates to end-users to keep the OS up to date.
The update process has not been a smooth one. Microsoft's VP of Windows last week acknowledged that updating can be "disruptive". It was in October of 2018 when Microsoft rolled out version 1809 and many users found that their files had been deleted due to a bug. I'm not sure if the bug was part of the update or the new OS itself but Microsoft halted the update for 6 weeks until the issue had been resolved.
It's not an easy task for Microsoft. There are over 800 million PCs running Windows 10 worldwide. Unlike Apple which controls every facet of their products, there are hundreds if not thousands of PC hardware manufacturers. Since some make only components to be used in a finished PC, this leads to innumerable variations in hardware. Add to that all the available software that can be installed and user personalization that makes anticipating every outcome difficult if not impossible.
It is important that you update your Windows to ensure that security holes and bugs have been patched. Not doing so leaves your computer exposed to hackers and criminals who are always evolving as well as the tools they use to attack your system and steal your data.
There is a new feature coming with the next Windows feature release called "SandBox" that will allow your computer to run in a secure lightweight environment to protect your computer from Malware without affecting the normal Windows installation. Believe me, you will want this.
There are major updates available now for Windows version 1809 and we are on the cusp of the first major Windows feature release of 2019, version 1903 due for release any day now.

GA Tech 1.3 million data breach, Albany NY, latest victim of Ransomware. Is your Office 365 OneDrive and SharePoint safe?
Potentially 1.3 million current and former students affected by Georgia Tech data breach
Although world renowned for its computer science programs, Georgia Tech has exposed the second data breach to occur at the school in less than a year. The news was announced yesterday and the potential fallout of exposed names, addresses, SSNs, and birth dates could affect 1.3 million current and former students.

New York capital hit by ransomware attack, taking services offline
Albany, NY is just the latest city to become a victim of ransomware, the city announced Saturday, 03/30/19. City services impacted so far is limited to its ability to offer birth, death and marriage certificates. People seeking these services are having to visit state vital records offices.
Albany police are said to have no access to any service or program that relies on internet connection.
The situation is still being assessed and inquiries to the Mayor's office on Monday were not being responded to.
Ransomware attacks on cities have been increasing due to lax security and that the attack is more likely to be successful. Citizens depend on city government services thus city official feel more pressure to resolve the situation.
Gregory McGee, the Police union's vice president, said that the ransomware was also affecting computers in patrol cars related to "incident and accident reports." "One has to ask the question of why a police department with sensitive information is on the same network that was so easily attacked."
In March of 2018, Atlanta, GA was targeted. City officials refused to pay and recently the ongoing recovery process has been estimated to cost $17 million.
Two Iranian hackers have been charged by the Justice Department with using malware to attack targets with critical infrastructure or that offer critical services. Hospitals have been targetted and in many cases, the victims could not pay but the alleged hackers have still taken in $6 million. The Iranians remain at large since there is no extradition treaty with Iran.

Office 365, OneDrive and SharePoint folders. Are you safe from Ransomware?
Many companies today have Office 365 and use OneDrive and Sharepoint to synchronize their onsite server and Cloud services. This is a backup in the traditional sense. However, ransomware encrypts the files on your system, rendering them unusable. They cannot be opened or viewed without the key to decrypt them. Hence the term ransomware because the attacker generally will request a payment be made in cryptocurrency to obtain the key.
If your server or computer is attacked by ransomware and it syncs with your cloud then it will overwrite the files in the cloud. Fortunately, OneDrive has a feature called versioning. Up to 50 previous versions of any Microsoft Office file exists and you can revert to the good version that was overwritten.
Unfortunately, this works only for MS Office files. Ransomware will encrypt jpegs, PDFs and all files located on a computer. So all non-related Microsoft Office files are subject to be lost. It will also be time-consuming and troublesome to have to reversion all your Office data.
It is therefore imperative that you keep multiple day backups of your data. You should keep multiple days in case the attack happens and goes undetected for a day or two. If you have only a single day backup, say the same backup occurs to the same external drive daily and you get attacked, you could end up with a backup of the encrypted data.
Redundant backups are a good insurance policy in the event of a Malware attack. Hardware failure is no longer the main threat to your data. Organizations and staff must protect against the constant threat of malware and ransomware in today's IT climate. A good backup plan is essential to safeguard your data.
Start examining your backup and security needs today before it's too late.
Support for Windows 7 ending 01/14/2020.
If you are still using XP based systems then there has not been any security patches or updates to your computer since 04/08/2014. Experts agree that you should not use Windows XP based computers to access information and email on the internet. There aren't any modern browsers or AV software for these computers available any longer and the risks to your data and personal info is exponential.
In approximately 8 months support for Windows 7 ends.
Plan today to upgrade your systems to a new DForce Intel based computer with the newest Generation 8 and 9 Intel processors running Windows 10.

Software glitches, Fatal results. Boeing 737 Max and now Tesla Autopilot hacked.
Everyone I'm sure has heard about the awful fate of the 2 Boeing 737 Max crashes.
The crashes were linked to a faulty device called the angle-of-attack sensor which incorrectly activated an automated system that caused a nosedive that the pilots could not recover from. As of yesterday 4/1/19 the fleet remains grounded.
Boeing’s software update for its troubled 737 Max jetliners has been delayed after the company deemed further work was needed on the fix before it was submitted to the Federal Aviation Administration.
The Max, Boeing’s newest plane, was grounded by regulators around the world in March after the crashes of two Max aircraft within five months.
As part of its process to return the Max to the air, Boeing has been working on a software update to new anti-stall system, known as MCAS, that was included in the Max.

Hackers reveal how to trick a Tesla into steering towards oncoming traffic
It's bad enough when your computer crashes due to a faulty update or glitch in the software. Hell, I was mad when Sony updated my Android TV and it crashed daily until I got another update. However, I don't want to think about such errors threatening my well being and health or that of others.
The latest thing to worry about is autopilot on your car. Hackers have now revealed that they were able to trick Tesla's autopilot feature to steer into the wrong lane remotely.
The team of hackers was able to insert malicious code into the steering wheel controls and connect it to a Bluetooth gamepad controller.
The Autosteer mode of the vehicle use camera feeds and computer vision to navigate traffic lanes. The researchers were able to tamper with how the vehicle recognizes traffic lanes.
Tencent researchers tested out their theory by applying some simple stickers to a road surface, and this confused the machine vision system enough to go AWOL and, theoretically, could be used to divert these cars into oncoming traffic.
Tesla reports that this is not a real concern of theirs since the driver can simply override Autopilot at any time by using the steering wheel or brakes. However, Boeing said the same thing about the override for the pitch control on the 737 Max only some pilots had not been trained on this. I hate to think about the average Tesla driver's abilities, not paying attention or panic overriding correct actions.
Technology is a wonderful thing but when it comes to certain things, people should not become overly reliant upon technology. Tencent researchers, the hacker group who brought this to light, did so in the name of safety. I'd hate to think what a teenager would do with the knowledge and capability to execute this.
When it comes to Tesla, the company is not exempt from the same security concerns -- having recently been hacked at Pwn2Own -- but the vehicle range's computer systems can also come in useful, too, beyond Autopilot. Earlier this week, the Tesla's Model 3 new Sentry Mode caught a vandal in the act while she was scratching up the car, leading to her arrest.
