Black Majority Schools Face Alarming Internet Security Risks, Report Finds

/in


There is a large digital divide affecting low-income and Black or Indigenous majority schools, a recent report by Internet Safety Labs (ISL) has found.

Ads and trackers

The report “Demographic Analysis of App Safety, Website Safety, and School Technology Behaviors in US K-12 Schools” explores technological disparities in American schools, focusing mainly on marginalized demographics.

This research expands on ISL’s previous work on the safety of educational technology across the country and is supported by the Internet Society Foundation. It reveals how schools of different backgrounds use technology and the risks involved.

One concerning finding is that websites for schools with mostly Black students were the least safe.

One-third of these schools had advertisements on their websites—a rate much higher than the national average—and 100% of the websites had trackers monitoring visitor behavior.

Privacy or digital divide?

The study also highlights a broader problem: a digital divide in how technology is used in education.

Schools in the lowest income bracket, making between $20,000 and $39,000, were among the least likely to provide their students with computing devices. This limits these students’ experience with technology.

Furthermore, the technology that is recommended or required often poses privacy risks, including apps filled with digital and behavioral ads.

Similar trends were seen for schools with the most American Indian/Native Alaskan students, leading to concerns about how this digital divide impacts students’ learning and their understanding of technology.

What Is The Solution?

The report suggests several actions for schools, school districts, and policymakers.

It recommends eliminating digital ads and tracking devices on school websites.

It also emphasizes the importance of schools being transparent about the technology they use, suggesting they publish a comprehensive list of required technology so students and parents know what’s expected.

Finally, it suggests schools should thoroughly vet all technology they recommend or require for educational use, to ensure it’s safe and appropriate…

Jet stream will get faster as climate change continues, study finds

Jet stream will get faster as climate change continues, study finds

A new study in Nature Climate Change takes one of the first deep dives into how climate change will affect the fastest jet streams—the powerful, narrow winds in the upper atmosphere that steer much of the Earth’s weather systems and are connected to outbreaks of severe weather.

The research, by UChicago Prof. Tiffany Shaw and National Center for Atmospheric Research scientist Osamu Miyawaki, suggests that as the world warms, the fastest upper-level jet stream winds will get faster and faster—by about 2% for every degree Celsius the world warms. Furthermore, the fastest winds will speed up 2.5 times faster than the average wind.

“Based on these results and our current understanding, we expect record-breaking winds,” said Shaw, “and it’s likely that they will feed into decreased flight times, increased clear-air turbulence and a potential increase in severe weather occurrence.”

Wind, weather and warming

Partly prompted by recent news reports of speed-record-breaking flights over the Atlantic, Shaw and Miyawaki began to investigate and realized there had been very little exploration of how the very fastest jet stream winds would respond to climate change.

To fill this gap, they combined climate change models with what we know about the physics of jet streams.

Jet streams usually move from west to east around the globe in the upper atmosphere, about six miles (10 kilometers) above us. We know that jet streams strongly influence the weather we experience on the ground—especially air temperature, winds and weather patterns, and storms. They also influence the occurrence of severe storms, tornadoes, hail and severe wind.

Jet streams form because of the contrast between the cold, dense air at the poles and the warm, light air in the tropics, in combination with the rotation of the Earth. (This was first shown in…

WatchGuard Threat Lab Report Finds Endpoint Malware Volumes

/in


SEATTLE, Oct. 04, 2023 (GLOBE NEWSWIRE) — WatchGuard® Technologies, a global leader in unified cybersecurity, today announced the findings of its latest Internet Security Report, detailing the top malware trends and network and endpoint security threats analyzed by WatchGuard Threat Lab researchers. Key findings from the research include 95% of malware now arriving over encrypted connections, a decrease in endpoint malware volumes despite campaigns growing more widespread, ransomware detections on the decline amid a rise in double-extortion attacks, older software vulnerabilities persisting as popular targets for exploit among modern threat actors, and more. 

“The data analyzed by our Threat Lab for our latest report reinforces how advanced malware attacks fluctuate in occurrence and multifaceted cyber threats continue to evolve, requiring constant vigilance and a layered security approach to combat them effectively,” said Corey Nachreiner, chief security officer at WatchGuard. “There is no single strategy that threat actors wield in their attacks and certain threats often present varying levels of risk at different times of the year. Organizations must continually be on alert to monitor these threats and employ a unified security approach, which can be administered effectively by managed service providers, for their best defense.” 

Among the most notable findings, the latest Internet Security Report featuring data from Q2 2023 showed:

  • Ninety-five percent of malware hides behind encryption. Most malware lurks behind SSL/TLS encryption used by secured websites. Organizations that don’t inspect SSL/TLS traffic at the network perimeter are likely missing most malware. Furthermore, zero day malware dropped to 11% of total malware detections, an all-time low. However, when inspecting malware over encrypted connections, the share of evasive detections increased to 66%, indicating attackers continue to deliver sophisticated malware primarily via encryption. 
  • Total endpoint malware volume is down slightly, though widespread malware campaigns increased.There was a slight 8% decrease in endpoint malware detections in Q2 compared to the previous…

court finds teenagers carried out hacking spree

/in


A court has found an 18-year-old from Oxford was a part of an international cyber-crime gang responsible for a hacking spree against major tech firms.

Arion Kurtaj was a key member of the Lapsus$ group which hacked the likes of Uber, Nvidia and Rockstar Games.

A court heard Kurtaj leaked clips of the unreleased Grand Theft Auto 6 game while on bail in a Travelodge hotel.

The audacious attacks by Lapsus$ in 2021 and 2022 shocked the cyber security world.

Kurtaj is autistic and psychiatrists deemed him not fit to stand trial so he did not appear in court to give evidence.

The jury were asked to determine whether or not he did the acts alleged – not if he did it with criminal intent.

Another 17-year-old who is also autistic was convicted for his involvement in the activities of the Lapsus$ gang but can not be named because of his age.

The group from the UK, and allegedly Brazil, was described in court as “digital bandits”.

The gang – thought to mostly be teenagers – used con-man like tricks as well as computer hacking to gain access to multinational corporations such as Microsoft, the technology giant and digital banking group Revolut.

During their spree the hackers regularly celebrated their crimes publicly and taunted victims on the social network app Telegram in English and Portuguese.

The trial was held in Southwark Crown Court in London for seven weeks.

Hacking spree one

Jurors heard that the unnamed teenager started hacking with Kurtaj in July 2021 having met online.

Kurtaj aided by Lapsus$ associates, hacked the servers and data files of telecoms company BT and EE, the mobile operator, before demanding a $4m (£3.1m) ransom on 1 August 2021.

Lapsus text message

The hackers sent out threatening text messages to 26,000 EE customers

No ransom was paid but the court heard that the 17-year-old and Kurtaj used stolen SIM details from five victims to steal a total of nearly £100,000 from their crytpocurrency accounts which were secured by their compromised mobile phone SIM identities.

Both defendants were initially arrested on 22nd January 2022, then released under investigation.

Hacking spree two

That did not deter the duo who continued hacking with Lapsus$ and successfully breached Nvidia, a Silicon Valley tech giant…
