Can you zoom in on that license plate?

The recent video enhancement post sparked additional interest in the subject. Upon doing some more research, it became clear that enhancing is only part of the picture. (Geez, I am starting to sound like Mr. Peabody.) 

Even more important is investing in technology which works in the first place. For example, the video surveillance system required in a small store is not what works best for surveying a parking lot.

The following explanation at Jim Hoerricks' blog is really insightful and educational...

Can you zoom in on that license plate? Can you zoom in on his face? Why can't you make this image clearer. These are questions that many forensic video analysts deal with on a daily basis. To illustrate the answer to these questions, let's consider this image:


This Monitoring image comes from an Avigilon system's 16 megapixel camera.

With the above image in mind, let's consider the outstanding advice from the UK's Home Office Scientific Development Branch:

To judge the quality of images that will be necessary, you will need to take into account the purpose for which CCTV is used and the level of quality that will be necessary to achieve the purpose. The Home Office Scientific Development Branch (HOSDB) recommends identifying the needs of a CCTV system by using four categories:
  1. Monitoring: to watch the flow of traffic or the movement of people where you do not need to pick out individual figures.
  2. Detecting: to detect the presence of a person in the image, without needing to see their face.
  3. Recognising: to recognise somebody you know, or determine that somebody is not known to you.
  4. Identifying: to record high quality facial images which can be used in court to prove someone’s identity beyond reasonable doubt.
Take a look at the picture above. Can you make out faces or license plates? No. So, if your purpose is to identify these items, that picture view just won't do. 

With Photoshop, we can zoom in. Let's see what happens.



This Detecting view comes from zooming in a 16 megapixel image.

We can now see the people and vehicles more clearly. We can gain a general awareness of types of vehicles. We are closer to identifying them, but we don't have anything yet that will help us to prove identity beyond a reasonable doubt. We can zoom in further to see if we can Recognise anyone.


This Recognising view comes from zooming in a 16 megapixel image.

 At this level of magnification, someone who knows this person or car should be able to say, "that's him" or "that's not the man/car you are looking for." At this point, we can begin to accurately describe the individual in the scene. Let's zoom in some more to see if we can positively identify this man and the car.



This Identifying view comes from zooming in a 16 megapixel image.

With a 16 megapixel image, we can even zoom in closer than this image. But notice what's happened along the way. We've sacrificed field of view for detail. No longer are we looking at the whole parking lot (monitoring). We can't see the other people who are walking around (detecting). In order to identify this individual, we've had to zoom in so far that we've excluded much of this scene from our view. A CCTV Installer might position a camera/lens combination at a choke point specifically to get facial recognition whilst installing other cameras around the area to monitor and detect movement of unauthorised persons.

But what about real life. The good folks at Avigilon have a small piece of a very large market. What if that same monitoring image was only 4CIF or 2CIF. Could we still zoom in and identify the individuals in the scene? You be the judge.

The image from Avigilon contains 15,824,256 pixels and can come in a lossless RAW format.
This image contains only 426,400 pixels and is compressed. 

With an almost 97% reduction in the amount of available pixels and the additional compression, the results speak for themselves.

The result of zooming in on a low pixel count image.

So, the answer to "can you zoom in on that license plate" is ... it depends on the quality of the image and the number of available pixels. ~Jim Hoerricks - author of Forensic Photoshop, a comprehensive imaging workflow for forensic professionals

Zoom’s Encryption Is “Not Suited for Secrets” and Has Surprising Links To China, Researchers Discover

Meetings on Zoom, the increasingly popular video conferencing service, are encrypted using an algorithm with serious, well-known weaknesses, and sometimes using keys issued by servers in China, even when meeting participants are all in North America, according to researchers at the University of Toronto.

The researchers also found that Zoom protects video and audio content using a home-grown encryption scheme, that there is a vulnerability in Zoom’s “waiting room” feature, and that Zoom appears to have at least 700 employees in China spread across three subsidiaries. They conclude, in a report for the university’s Citizen Lab — widely followed in information security circles — that Zoom’s service is “not suited for secrets” and that it may be legally obligated to disclose encryption keys to Chinese authorities and “responsive to pressure” from them.
Zoom could not be reached for comment. more

Zeroing in on Zoom’s Threat to Financial Services

COVID-19 has induced a significant shift in the way we work. Remote is the new reality.

There may be, however, a tremendous cost to Zoom’s convenience... For many, Zoom has been the answer to staying connected in the workplace.

Simply put, the widespread adoption of Zoom amid a global pandemic might be the security vulnerability of the decade. 


In fact, any financial services organization using the service should immediately assume their user credentials are under malicious parties’ control.

In recent weeks, New York Attorney General Letitia James has probed Zoom’s data security strategy, and whether the company’s security protections can keep up with the spike in users. It is also our understanding the FBI, among other federal government agencies, has also prohibited the use of Zoom and WebEx due to security concerns. more

'Zoom-bombed' | Salary Cuts Call Eavesdropped on by Rival Company

Staff at national news outlet The Independent were on a ‘confidential and sensitive video’ Zoom call to learn about salary cuts and furloughs when it was ‘zoom-bombed’ by an employee from a rival media organisation. more


Mark Di Stefano, a reporter with the Financial Times, allegedly entered meetings held over the video conferencing app by the Independent and the Evening Standard.

Stefano, according to the Independent, brazenly joined the meeting by using his work email address. This caused Stefano’s name to appear on the call, although his camera remained disabled.

The journalist reportedly joined for 16 seconds before logging out but returned soon after by logging in with his phone number.

Not long after the call, Stefano sent out a series of tweets describing topics that the Independent says were discussed during the staff meeting.

Stefano described information on everything from pay cuts to the outlet’s issues with falling ad revenue. more

Being Zoom'ed on Zoom has Organizations Worried, or they should be...

...experts warn that a rush to hold virtual meetings through Zoom, which has close to 13m monthly active users, could pose security risks.

The threat is so significant that British Ministry of Defence staff were told this week that the use of Zoom was being suspended with immediate effect while "security implications" were investigated.

The biggest worry is that a sudden reliance on Zoom could allow opportunistic hackers to quietly observe video calls as executives are focused on responding to the spread of coronavirus.

...the idea of strangers barging into virtual meeting rooms should raise alarm. more

Online Zoom classes were disrupted by individuals spewing racist, misogynistic or vulgar content. Experts say professors using Zoom should familiarize themselves with the program's settings. more

500,000 Hacked Zoom Accounts Given Away - Free On The Dark Web

New users have flocked to the Zoom video conferencing platform as businesses, schools, and other organizations look for ways to meet safely during the Coronavirus pandemic. Unfortunately many of those brand new accounts appear to have been secured with old passwords.

The cyber risk assessment experts at Cyble recently discovered a hacker selling stolen Zoom credentials at dirt-cheap prices — and in some cases giving them away for free.

Cyble purchased more than 530,000 on an underground hacking forum for next to nothing. Several of the company’s clients were among the stolen credentials, which also included personal meeting URLs and Zoom host keys. Cyble reached out and confirmed that the credentials were indeed valid.

Password re-use remains a huge security issue for the general public.
Fatigued users feel like they can’t remember yet another password so they set up new accounts using an old stand-by.

The problem is that by now all of those old stand-by passwords have been filed away in databases by criminal hackers. They’re actively using them to break into accounts using brute force attacks.
Usernames, email addresses, and passwords have been exposed by the billions over the past several years. Creating a new account on Zoom — or any service, for that matter — is simply not a good idea.

Hackers will come knocking. It’s not a question of if. It’s a question of when. more

Intense Competition Leads to Attempted Corporate Espionage

via Lexology - from the Troutman Papper law firm.
Side Note: Troutman Pepper has formed a Corporate Espionage Response Team to help clients combat the increasing incidence of corporate espionage.

Arthur AI, a New York-based AI company, received a request for a Zoom demonstration of its technology from a startup called OneOneThree. The head of technology at OneOneThree, Yan Fung, expressed interest in purchasing Arthur AI’s technology. But there were some immediate red flags.

First, prior to the Zoom meeting, Arthur AI employees recognized that OneOneThree had no website. The Timesarticle says that Fung told Arthur AI at the time that OneOneThree was in “stealth mode,” which is why it had no website. Then, when Arthur AI asked Fung to sign a nondisclosure agreement (NDA), he reportedly asked Arthur AI to “hold off on the NDA,” and Arthur AI agreed.

Despite these issues, a Zoom meeting was arranged to demo the technology. Fung said Karina Patel, OneOneThree’s “main engineer,” would dial in to the meeting. However, during the Zoom meeting, an attendee logged in under the name of Aparna Dhinakaran, which an Arthur AI employee immediately recognized as a founder of Arize AI, a rival startup. When recognized, the attendee quickly logged off. Arthur AI later deduced that Fung was, in fact, an employee of Arize AI named Dat Ngo, and OneOneThree was an inactive company of his.

After the call concluded, one of Arthur AI’s employees messaged Ngo via LinkedIn direct messaging. Ngo responded by trying to recruit the Arthur AI employee, according to the Times article. more

Lessons Learned:
  • Require NDAs Every Time.
  • Perform Proper Due Diligence and Act Consistently With Your Findings. 
  • Only Use Secure Communication Channels and Restrict Recording.
  • Train Employees on Spotting and Responding to Potential Threats.
  • Conduct a Prompt and Careful Investigation Into Suspected Activity.

Eavesdropper Scams Financial Advisor | Prevention Tips

Early in April, a financial advisor and her team met with an insurance company wholesaler via the video conferencing platform Zoom.

Unbeknownst to them, another participant had joined the virtual meeting.

As the hacker captured details, the wholesaler named the price of a new policy and the advisor agreed to the terms.

...It’s likely that even before the meeting ended the eavesdropper generated an email to the advisor so that it appeared to come from the insurer. In a later forensic analysis, an overlooked detail revealed the spoof: a single letter the hacker changed in the insurance company’s name.

After the meeting ended, the advisor received the message with instructions to wire money — in the low six figures — to a New York bank account. She did as instructed, sending the money to the hacker. more

———How to prevent Zoombombing in your video chats in 4 easy steps———

1. Don't use your Personal Meeting ID for the meeting. Instead, use a per-meeting ID, exclusive to a single meeting. Zoom's support page offers a video walk-through on how to generate a random meeting ID for extra security.

2. Enable the "Waiting Room" feature so that you can see who is attempting to join the meeting before allowing them access. Like many other privacy functions, a skillful disrupter can sometimes bypass this control, but it helps to put another hurdle in their route to chaos.

Zoom offers a support article here as well. To enable the Waiting Room feature, go to Account Management > Account Settings. Click on Meeting, then click Waiting Room to enable the setting.

3. Disable other options, including the ability for others to Join Before Host (it should be disabled by default, but check to be sure -- see below). Then disable screen-sharing for nonhosts, and also the remote control function. Finally, disable all file transferring, annotations and the autosave feature for chats...

4. Once the meeting begins and everyone is in, lock the meeting to outsiders ... and assign at least two meeting co-hosts. The co-hosts will be able to help control the situation in case anyone bypasses your efforts and gets into the meeting. more

Recent Hot Mic News...

Eavesdropping Bugs and Hot Mics have something in common... both capture private conversations not for publication. Technical Surveillance Countermeasures  (TSCM) inspections can combat the bugging. Hot Mic avoidance is more a do-it-yourself exercise. It requires you listen to your mom's advice, "If you don't have anything nice to say, don't say it."


Judge Ridicules Attorney After Hearing

IL - A Cook County judge this week was caught on a YouTube livestream mocking an attorney who had appeared before him for arguments earlier in the day.

“Can you imagine waking up next to her every day? Oh, my God,” Judge William Raines said of attorney Jennifer Bonjean. “... I couldn’t have a visual on that if you paid me.”

A link to the video of Tuesday’s livestreamed court call was available for viewing as recently as Thursday morning. After Raines had finished hearing cases, he began to chat with two Cook County prosecutors and a Cook County assistant public defender about the legal argument Bonjean had participated in earlier that day. He apparently did not realize the conversation was still being broadcast live on YouTube.

“I’m reliving (Assistant State’s Attorney) Todd Dombrowski’s conversation with Miss Bonjean,” he said, apparently unprompted. “... Did you see her going nuts? Glasses off, fingers through her hair, the phone’s going all over the place, it’s insane.more

FutureWatch: How Police Can Spy on a Whole City

CA - In a secret test of mass surveillance technology, the Los Angeles County Sheriff's Department sent a civilian aircraft over Compton, California, capturing high-resolution video of everything that happened inside that 10-square-mile municipality.

Compton residents weren't told about the spying, which happened in 2012. 

"We literally watched all of Compton during the times that we were flying, so we could zoom in anywhere within the city of Compton and follow cars and see people," Ross McNutt of Persistent Surveillance Systems told the Center for Investigative Reporting. 

The technology he's trying to sell to police departments all over America can stay aloft for up to six hours. Like Google Earth, it enables police to zoom in on certain areas. And like TiVo, it permits them to rewind, so that they can look back and see what happened anywhere they weren't watching in real time.  (more) (video)

FutureWatch: Smartphone Comes with Optical Spy Pen

Click to enlarge.
Electronic pen device having optical zoom – Patent # US 10,198,649 – Feb. 5, 2019

Abstract

The electric pen device includes an optical system including a lens and an image sensor configured to convert an image signal of light that has passed through the optical system to an electrical signal. The electric pen device includes a control board configured to interact with an electronic device and a communication module configured to communicate by wire or wirelessly with the electronic device, so that an image or a picture taken by a camera is confirmed and an optical zoom is controlled from the external electronic device. more

FutureWatch spy implications: Phone may be concealed in the pocket, backpack, or nearby desk drawer. Take high quality photos by aiming the top of the pen, pressing a button, and automatically transmitting the photo back to the phone. Pretty covert. No word about it transmitting audio, yet. Leaving phones outside of the conference room won't be enough. You'll have to check the pens, too. 

Need a spy pen camera you can actually buy today, or worry about being used to steal your secrets? Check here. ~Kevin

Thanks to our sharp-eyed Blue Blaze Irregular in the shadows of Pennsylvania for this.

Apple Temporarily Disables Walkie Talkie on Apple Watch Over Eavesdropping Concerns

Less than 24 hours after Apple issued a background update to remove a vulnerability in Zoom’s Mac app that installed a surreptitious web server that could activate the video camera without the user’s permission, Apple has disabled another app for a possible security breach. And this time it’s one of its own: Walkie Talkie.
Walkie Talkie was introduced with watchOS 5 as a quicker way to communicate between Apple Watches. Apple promotes it as “a new, easy way to have a one-on-one conversation with anyone who has a compatible Apple Watch.” However, it might not be as private as you think. Apple announced late Wednesday that it was temporarily disabling the Walkie Talkie on the Apple Watch due to eavesdropping concerns. more

The Latest Video Enhancement Trick: De-Blurring

About a year ago I looked at work by two video enhancement specialists; Doug Carner, CPP/CHS-III of Forensic Protection and Jim Hoerricks - author of Forensic Photoshop, a comprehensive imaging workflow for forensic professionals

Today, Doug advised me of a trick that every security professional should have up their sleeve, de-blurring. He explained how he de-blurs motion this way...

"Light originates and reflects from objects in very predictable ways. As the camera and object move, they distort the captured image. These distortions can be reversed using a filter that acts like mathematical eye glasses.

For this example, we used the bent light streak seen at the far right of the license plate. The process could have just as easily been applied to the mud flaps or tires."

Wow, major difference!

This got me thinking. How good will this technology become?

Just two months ago, Adobe gave the world a sneak peek.

When you view this video, set it to HD and go full screen. The magic begins about 2 minutes into the clip and continues with several photos being blur corrected.

Unfortunately, this was only a sneak preview. It is not available to the general public in Photoshop yet.

Just to re-cap, here are some of the things Doug can do to enhance your crummy videos...
• High-resolution video and audio extraction or capture
• Adaptive military-grade video jitter stabilization
• Video de-interlace, de-sequence and de-multiplex
• Intelligent temporal noise and artifact suppression
• Fast-Fourier compression and camera age reversal
• Sub-pixel shift fusion over time, space and frequency
• Adjust video brightness, contrast, saturation and size
• Color channel isolation and focus/motion blur correction
• Audio noise suppression and speech amplification
• Video zoom, trim, crop and speed adjustments
• Multiplex to original with event highlight for court exhibit
• Image extraction, cropping, enlarging and printing

Eavesdropping on the Sounds of Your Typing

New acoustic attack steals data from keystrokes with 95% accuracy
(a little background music, please)

A team of researchers from British universities has trained a deep learning model that can steal data from keyboard keystrokes recorded using a microphone with an accuracy of 95%.

When Zoom was used for training the sound classification algorithm, the prediction accuracy dropped to 93%, which is still dangerously high, and a record for that medium.

Such an attack severely affects the target's data security, as it could leak people's passwords, discussions, messages, or other sensitive information to malicious third parties. more

"...and we also send the feed to Santa."

UK - Motorists using mobile phones are being caught by a police spotter plane.

The £300,000 "eye in the sky" flies at around 10,000 ft - and uses a powerful camera which can zoom in on a driver with amazing precision.

If someone is spotted using a phone, the police alert colleagues on the ground to stop them.

The aircraft is being used by Cheshire Police on its way to and from other jobs. A police spokesman said: "The camera is of a military spec and can magnify to almost any degree required." (more)

Obviously, there is no need to spend about $600,000.00
(not to mention the fuel bill), or fly at an altitude of 10,000 feet to catch people driving while using mobile phones. Heck, the fine alone would have to be in the thousands to make this cost-effective. However, the "other jobs" might make this worthwhile, and releasing a nutty story like this to a sensational-hungry press and gullible public; free frosting on the enforcement cake!
