A ‘persistent hum’ of plasma has been detected by Voyager 1 as it travels through interstellar space.
After launching into space 44 years ago, the NASA Voyager 1 probe has become the most distant human-made object in space – and it’s still going strong.
Now, in a paper published in Nature Astronomy, a team of researchers said a persistent vibrating hum of plasma has been detected by the spacecraft.
Voyager 1 flew past the edge of our solar system almost a decade ago, with NASA confirming its entry to interstellar space in 2014. Now, its instruments have detected the constant drone of interstellar gas, or plasma waves.
Stella Koch Ocker, a doctoral student in astronomy at Cornell University, uncovered the emission. “It’s very faint and monotone, because it is in a narrow frequency bandwidth,” she said. “We’re detecting the faint, persistent hum of interstellar gas.”
James Cordes, senior author of the research and professor of astronomy at Cornell, said the interstellar medium is like a quiet or gentle rain. “In the case of a solar outburst, it’s like detecting a lightning burst in a thunderstorm and then it’s back to a gentle rain.”
What does it mean for science?
The discovery could give scientists an understanding of how the interstellar medium interacts with the solar wind and how the protective bubble of the solar system’s heliosphere is shaped and modified by the interstellar environment.
Ocker also believes that there is more low-level activity in the interstellar gas than scientists had previously thought, which could allow researchers to track the spatial distribution of plasma.
Cornell University research scientist Shami Chatterjee said researchers have never had the chance to continuously track of the density of interstellar space before. “Now we know we don’t need a fortuitous event related to the sun to measure interstellar plasma,” he said.
“Regardless of what the sun is doing, Voyager is sending back detail. The craft is saying, ‘Here’s the density I’m swimming through right now. And here it is now. And here it is now. And here it is now.’ Voyager is quite distant and will be doing this continuously.”
In early January, Brooks Nader, a 26-year-old Sports Illustrated swimsuit model, was walking home alone from a night out in New York when she received a disturbing iPhone notification telling her she was carrying an “unknown accessory”.
“This item has been moving with you for a while,” the alert read. “The owner can see its location.”
That’s when she knew “something wasn’t right”, Nader told the NBC news program Today. Nader discovered that somebody had slipped an Apple AirTag into her coat pocket while she was sitting in a restaurant earlier. Unbeknown to her, the device tracked her location for four hours before Apple’s abuse prevention system triggered the notification to her phone.
AirTags are wireless, quarter-sized Bluetooth devices that retail for $29 each. Apple launched the product in April 2021 as tracking tools that users can pair with the company’s Find My app to help locate lost belongings, like backpacks or car keys.
Yet AirTags have proven easy to abuse – police in New York, Maryland, Idaho, Colorado, Georgia, Michigan, Texas and elsewhere both within the US and internationally, have reported instances of AirTags being used to stalk individuals, as well as to target cars for theft.
Last week, the New Jersey Regional Operations & Intelligence Center issued a warning to police that AirTags posed an “inherent threat to law enforcement, as criminals could use them to identify officers’ sensitive locations” and personal routines.
AirTags have abuse-mitigation features, including pop-ups like the one Nader received, and an alarm that beeps at 60 decibels (a conversational volume) after the AirTag has been away from its owner anywhere between eight to 24 hours.
Near the end of 2021, the company released a new Android app called Tracker Detect, which was designed to help people who own Androids discover suspicious AirTags near them – yet the app must be proactively downloaded and kept active to be effective, and is only compatible with Android 9 or higher.
The outcome of more anti-stalking mechanisms is that more people are realizing they are being stalked. On 14 January, police in Montgomery county, Maryland, responded to a call from a person who was stalked home from a movie theater after an AirTag was planted on their car. Around the same time, two California women called 911 after receiving a notification that their whereabouts were being tracked while out shopping. A 30 December report from the New York Times cites seven women who believe AirTags were used to surveil them. On social media, posts from mainly women sharing their own experiences of being tracked by AirTags have drawn attention to the issue, with one TikTok video from November 2021 receiving more than 31m views.
If you suspect you’re being tracked, the conventional wisdom is not to head home, but rather call – or go to – the police. However, law enforcement responses to incidences of AirTag stalking have thus far been inconsistent, and help is not always guaranteed.
When Arizona’s Kimberly Scroop went to local police after receiving an iPhone notification that she was being tracked in September last year, “they were not interested in taking a report, they didn’t take my name or phone number,” she says. “They said if I noticed someone following me, to call the police then.”
Scroop went home and made a TikTok video about her experience being tracked, thinking she should “make as much noise as possible, so there was some public record of it” online in case anything bad happened to her. “I was having a mini panic attack, just really scared,” she says in the post that has now been viewed more than 5.5m times.
In New York, Jackie’s Law – passed in 2014 to allow police to charge people using GPS tracking devices to stalk victims even if the victims have not pressed charges – contributed to police in West Seneca’s decision to subpoena Apple for information about a case involving an AirTag attached to a victim’s car bumper. Nonetheless, Nader claims she was unable to file a report after being tracked in Tribeca, New York City, as police told her no crime had been committed.
In an official statement, Apple says it will cooperate with police “to provide any available information” about unknown AirTags people discover on their person or property. “We take customer safety very seriously and are committed to AirTags’ privacy and security,” says a spokesperson.
Ultimately, their built-in anti-stalking mechanisms and the fact that they can be easily disabled when discovered render AirTags less dangerous than other forms of stalkerware. “If you really are nefarious and evil and you really want to find someone, there are things that are much better than an AirTag,” in the $100 to $300 range, says Jon Callas, director of technology projects at the Electronic Frontier Foundation.
Indeed, stalking affects an estimated 7.5 million people in the United States each year, and one in four victims report being stalked through some form of technology, according to the Stalking Prevention Awareness & Resource Center. And it’s on the rise: a 2021 international study by the security company Norton found the number of devices reporting stalkerware daily “increased markedly by 63% between September 2020 and May 2021” with the 30-day average increasing from 48,000 to 78,000 detections. There are thousands of different stalkerware variants, such as Cerberus, GPS tracking devices and Tile, a Bluetooth-enabled AirTag competitor that announced a partnership with Amazon last spring.
To Callas, the conversation around AirTags is drawing much-needed attention to the potential for technology to be misused; he hopes more people will consider the safety risks of tracking devices, regardless of how innocent they seem. “If you make a generalized technology that helps you find your lost keys, it can help you find anything,” he says, “and that includes people”.
Small and medium-sized managed service providers (MSPs) could find themselves subject to the Network and Information Systems Regulations under government plans to tighten cybersecurity laws – and have got three months to object to the tax hikes that will follow.
NIS is the main law controlling security practices in the UK today. Currently a straight copy of the EU NIS Directive, one of the benefits of Brexit leapt upon by the Department for Digital, Culture, Media and Sport (DCMS) is the new ability to amend NIS’s reporting thresholds.
Bringing MSPs under NIS “would provide a baseline for expected cybersecurity provision and better protect the UK economy and critical national infrastructure from cyber security threats,” as UK.gov said in a consultation document issued on Wednesday. Its plans are for MSPs, currently not subject to NIS, to be brought into the fold. This includes defining what an MSP does, legally, and possibly ending NIS’ existing exemption on SMEs.
“The government recognises the strong need to minimise regulatory burden on small and micro-businesses particularly in a rapidly evolving industry such as this. However, recent incidents have highlighted the scale of risk that can be associated with managed service providers – regardless of their size,” said the consultation document.
In essence, if an “operator of essential services” or a critical national infrastructure business outsources something to your MSP, prepare for NIS compliance.
And the flip side: money
Enforcement of NIS is carried out by the ICO, which is getting a funding bonus if Parliament nods through the NIS amendments. Initially coming from general taxation, in time DCMS wants to “extend the existing cost recovery provisions to allow regulators (for example, Ofcom, Ofgem, and the ICO) to recover the entirety of reasonable implementation costs from the companies that they regulate.”
SMEs across the whole British economy are already familiar with this kind of “cost recovery” activity through stealth taxes such as the ICO’s data protection registration fee.
Andy Kays, chief exec of a managed detection and response firm in London called Socura, agreed that “further market intervention is required to help raise the bar to protect the UK economy.”
“However,” he added, “I do believe that interventions like Cyber Essentials, GDPR and NIS have raised the profile of cyber and data security in the UK, and have improved understanding and investment where they are applicable among businesses.”
Jake Moore, global cybersecurity advisor with Slovakian infosec firm ESET, also agreed, saying in a statement: “Essential services are desperately in need of better protection so these new laws will help direct businesses into a more secure offering with the help and direction required. Laws often may seem like they do not go far enough but digital crime is fast paced and the goal posts constantly move making such plans difficult to project or even become out of date by the time they land.”
The consultation closes on 22 April. As well as questions about money, DCMS is also asking about whether the regs should be extended to SMEs and how detailed they ought to be. Have your say via theses 66 pre-formatted questions. ®
The first cohort of the NDRC accelerator by Dogpatch Labs has four female co-founded start-ups and two international ones.
After taking over the NDRC accelerator from the Government in 2020, Dogpatch Labs gave it a makeover and launched its first cohort of 11 early-stage start-ups last year.
This year, they are running two accelerators with two separate cohorts and increasing the total number of participating start-ups from 11 to 14. The first cohort, H1, has a total of seven start-ups – four of which have female co-founders.
Announced yesterday (19 January), the first cohort also has two regional start-ups and two international start-ups co-founded by Irish CEOs who graduated from top international talent accelerators Antler and Entrepreneur First.
Here we list NDRC’s first cohort of seven early-stage start-ups in 2022 representing the next generation of Ireland’s start-up ecosystem who are gearing up for Demo Day on 7 April.
