‘fingerprint’ tracking method

In a discovery that could help law enforcement agencies across the globe track 3D-printed guns and counterfeit goods, a team of scientists at the University at Buffalo has found that no two 3D printers are the same, and that all have their own “fingerprints”.

The researchers claim to have developed what they describe as the world’s first accurate method for tracing a 3D-printed object to the device on which it was made.

Commenting on the discovery, study lead author Wenyao Xu said:”3D printing has many wonderful uses, but it’s also a counterfeiter’s dream. Even more concerning, it has the potential to make firearms more readily available to people who are not allowed to possess them.

“3D printers are built to be the same. But there are slight variations in their hardware created during the manufacturing process that lead to unique, inevitable and unchangeable patterns in every object they print.”

Xu and his team found that every layer of a 3D-printed object contains unique tiny wrinkles that can be used to identify various characteristics of the machine that was used to create it, including printer model type, filament, nozzle size and other factors.

To test their new tracking method, which they dubbed the PrinTracker project, the scientists printed five door keys from 14 common 3D printers.

They then scanned each of the door keys to create a digital image that was enhanced and filtered, allowing for the identification of the unique in-fill patterns of each object.

The researchers were then able to match each key to the printer on which it was produced with 99.8% accuracy.

Xu likened the tracking method to the ability to identify the source of paper documents, a practice that has been used by law enforcement agencies, printer companies and other organisations for decades.

Speaking with Vice News, David Chipman, Senior Policy Adviser at Giffords Law Center to Prevent Gun Violence, said: “For this to be useful to law enforcement who would be tracing guns, you’d have to have a record of the unique signature of every 3D printer being sold. We can only match it if we already have a record of it.”

While 3D-printed guns are currently widely considered as being flimsy and unreliable, experts fear that as the technology advances, they could be routinely used by criminals and terrorists on account of the fact they were considered to be nearly impossible to trace.

Crooked vendors exploiting flaw in eBay’s feedback system to con buyers into purchasing bogus and dangerous items

crooked vendors exploiting flaw in eBay’s feedback system

Buyers on eBay are being duped into purchasing substandard and counterfeit products due to a flaw in the online auction platform’s seller feedback system, according to an investigation conducted by UK consumer group Which?

The watchdog found that dishonest vendors can take advantage of these flaws by linking positive reviews of genuine products manufactured by companies such as Apple and Samsung to fake and low-quality items.

Which? found that crooked sellers are able to link thousands of positive reviews to eBay listings they have nothing to do with.

The organisation discovered that real reviews can be associated with fake products that are potentially dangerous, such as counterfeit mobile phone chargers that can pose a fire risk.

Sellers are able to do this by using “product IDs” associated with genuine items when adding their products to eBay, subsequently benefitting from the positive reviews those items have attracted.

The system is intended to make the process of listing products on eBay quicker and easier by allowing sellers to pull information from similar items that have a linked product ID.

As part of its investigation, Which? purchased 20 bogus Apple and Samsung accessories such as chargers and USB cables that were supposed to be official and shared the same reviews as products manufactured by the two technology firms

Calling for online ecommerce platforms to be held accountable for flaws in their seller feedback systems that allow dishonest vendors to pull the wool over buyers’ eyes, Head of Home Products and Services at Which? Natalie Hitchins said: “Our investigation has uncovered yet another example of online reviews being manipulated to mislead people.

“eBay’s product review system is confusing for consumers and could even direct them towards counterfeit or dangerous products sold by unscrupulous sellers.

“Online reviews influence billions of pounds of consumer spending each year.

“The [UK Competition and Markets Authority] must now investigate how fake and misleading reviews are duping online shoppers, taking the strongest possible action against sites that fail to tackle the problem.”

Responding to the findings of Which?’s investigation eBay said in a statement: “The research does not fully consider that there are distinctions between product reviews (which provide buyers with a holistic review of the same product), and seller feedback (which can be used to see specific reviews of a seller’s performance and may reflect the item’s condition).”

Earlier this month, Bloomberg reported that US politicians had called on lawmakers to hold ecommerce companies such as eBay and Amazon to account if they fail to prevent third-party vendors selling counterfeit or substandard products on their platforms.

Major ‘lover boy’ prostitution gang broken up by coalition of European law enforcement agencies

major ‘lover boy’ prostitution gang

A Romanian human trafficking and prostitution network that used the “lover boy” method to entrap young women before forcing them into sex work has been broken up a coalition of European law enforcement agencies.

The lover boy method, also known as the “Romeo pimp” method, involves young men seducing victims with the objective of coercing them into prostitution.

Lover boy traffickers groom their victims to believe they have entered into a serious romantic relationship before using emotional, psychological and sometimes physical abuse to intimidate them into working in the sex services industry.

Investigators from Spain, Romania, the Czech Republic and several other European nations were involved in the operation that resulted in the dismantling of the gang, which is said to have groomed and exploited at least 10 young women by forcing them to work as prostitutes.

The operation resulted in the arrest of 14 people in Romania and Spain, the safeguarding of 10 trafficking victims, and the confiscation of a number of items, including a quantity of cash, jewellery, expensive vehicles and several electronic devices.

In total, the agencies taking part in the effort raided 16 properties in the Czech Republic, Romania and Spain.

Having groomed their victims, Romanian members of the network would develop manipulative dependent relationships with the young women they targeted before forcing them into sex work.

Once under the traffickers’ control, victims would be abused and drugged before being sold onto other members of the network for as much as €6,000 ($6,632) each.

The women would then be moved between locations and countries on a regular basis as part of the gang’s efforts to avoid the attention of police.

Profits made by the network were laundered through the purchase of property, expensive jewellery and high-value cars.

Ongoing investigations into the network’s activities are focussed on the theory that it was working in cooperation with another gang.

Enquires have already resulted in the identification of more than 40 additional women who fell victim to the two criminal organisations.

In a statement, Europol said: “Europol facilitated the information exchange between the participating countries, provided coordination support and analysed operational information against Europol’s databases to give leads to investigators.

“Europol conducted a financial analysis based on the information provided which highlighted the extension of the criminal activity of the group and the presence and flow of illicit profits to other jurisdictions.”

Taking cocaine will not cure people struck down with the coronavirus, French government warns public

taking cocaine will not cure people infected with coronavirus

Authorities in France have been forced to inform the public that taking cocaine will not cure people infected with the coronavirus.

Taking to Twitter on Sunday, the French Ministry for Solidarity and Health told its followers that cocaine is not only ineffective when it comes to fighting the coronavirus, but is also a highly addictive drug that can cause serious harm to users’ health.

The government department was seeking to counter fake news circulating on social media that taking the drug could cure or prevent the virus, including doctored news stories that appeared to confirm the drug’s effectiveness at fighting the disease.

The ministry’s Twitter post included a link to a government information page that provided further guidance on disinformation circulating about the coronavirus outbreak.

As well as encouraging those worried about the coronavirus to start taking cocaine, online trolls have also suggested that bleach can also help fight the disease.

In a post on Twitter that has attracted many thousands of engagements, @Jordan_Sather_ told his followers: “Would you look at that. Not only is chlorine dioxide (aka ‘MMS’) an effective cancer cell killer, it can wipe out coronavirus too.

“No wonder YouTube has been censoring basically every single video where I discuss it over the last year.”

In August of 2019, the US Food and Drug Administration issued a warning about that dangers of consuming bleach, noting: “Drinking any… chlorine dioxide products can cause nausea, vomiting, diarrhoea, and symptoms of severe dehydration.”

As well as warning about cocaine’s inability to fight the coronavirus, the French government has also told members of the public that spraying bleach or alcohol on their bodies will not neutralise viruses they have already been infected with.

Elsewhere, US Vodka maker Tito’s Homemade was last week forced to urge people not to make DIY hand sanitiser out of its products.

Responding to one of its customers who said they had done just that, the company said on Twitter: “Per the CDC [Centres for Disease Control and Prevention], hand sanitizer needs to contain at least 60% alcohol. Tito’s Handmade Vodka is 40% alcohol, and therefore does not meet the current recommendation of the CDC. Please see attached for more information.”

For its part, the World Health Organisation, which today officially categorised the coronavirus as a pandemic, has published a webpage dispelling misinformation about the disease, noting that the virus cannot be killed of avoided by taking a hot bath or using hand dryers.
