Bluetooth Flaw Allows Remote Unlocking of Digital Locks
news.movim.eu / Schneier · 2 days ago - 18:56
Locks that use Bluetooth Low Energy to authenticate keys are vulnerable to remote unlocking . The research focused on Teslas, but the exploit is generalizable.
In a video shared with Reuters, NCC Group researcher Sultan Qasim Khan was able to open and then drive a Tesla using a small relay device attached to a laptop which bridged a large gap between the Tesla and the Tesla owner’s phone.
“This proves that any product relying on a trusted BLE connection is vulnerable to attacks even from the other side of the world,” the UK-based firm said in a statement, referring to the Bluetooth Low Energy (BLE) protocol—technology used in millions of cars and smart locks which automatically open when in close proximity to an authorised device.
Although Khan demonstrated the hack on a 2021 Tesla Model Y, NCC Group said any smart locks using BLE technology, including residential smart locks, could be unlocked in the same way.

Websites that Collect Your Data as You Type

Researchers from KU Leuven, Radboud University, and University of Lausanne crawled and analyzed the top 100,000 websites, looking at scenarios in which a user is visiting a site while in the European Union and visiting a site from the United States. They found that 1,844 websites gathered an EU user’s email address without their consent, and a staggering 2,950 logged a US user’s email in some form. Many of the sites seemingly do not intend to conduct the data-logging but incorporate third-party marketing and analytics services that cause the behavior.
After specifically crawling sites for password leaks in May 2021, the researchers also found 52 websites in which third parties, including the Russian tech giant Yandex, were incidentally collecting password data before submission. The group disclosed their findings to these sites, and all 52 instances have since been resolved.
“If there’s a Submit button on a form, the reasonable expectation is that it does something — that it will submit your data when you click it,” says Güneş Acar, a professor and researcher in Radboud University’s digital security group and one of the leaders of the study. “We were super surprised by these results. We thought maybe we were going to find a few hundred websites where your email is collected before you submit, but this exceeded our expectations by far.”

iPhone Malware that Operates Even When the Phone Is Turned Off
news.movim.eu / Schneier · 4 days ago - 20:59
Researchers have demonstrated iPhone malware that works even when the phone is fully shut down.
t turns out that the iPhone’s Bluetooth chip — which is key to making features like Find My work — has no mechanism for digitally signing or even encrypting the firmware it runs. Academics at Germany’s Technical University of Darmstadt figured out how to exploit this lack of hardening to run malicious firmware that allows the attacker to track the phone’s location or run new features when the device is turned off.
The research is the first — or at least among the first — to study the risk posed by chips running in low-power mode. Not to be confused with iOS’s low-power mode for conserving battery life, the low-power mode (LPM) in this research allows chips responsible for near-field communication, ultra wideband, and Bluetooth to run in a special mode that can remain on for 24 hours after a device is turned off.
The research is fascinating, but the attack isn’t really feasible. It requires a jailbroken phone, which is hard to pull off in an adversarial setting.

Attacks on Managed Service Providers Expected to Increase
news.movim.eu / Schneier · 5 days ago - 21:14
CISA, NSA, FBI, and similar organizations in the other Five Eyes countries are warning that attacks on MSPs — as a vector to their customers — are likely to increase. No details about what this prediction is based on. Makes sense, though. The SolarWinds attack was incredibly successful for the Russian SVR, and a blueprint for future attacks.
The NSA Says that There are No Known Flaws in NIST’s Quantum-Resistant Algorithms
news.movim.eu / Schneier · 5 days ago - 03:38 · 1 minute
Rob Joyce, the director of cybersecurity at the NSA, said so in an interview:
The NSA already has classified quantum-resistant algorithms of its own that it developed over many years, said Joyce. But it didn’t enter any of its own in the contest. The agency’s mathematicians, however, worked with NIST to support the process, trying to crack the algorithms in order to test their merit.
“Those candidate algorithms that NIST is running the competitions on all appear strong, secure, and what we need for quantum resistance,” Joyce said. “We’ve worked against all of them to make sure they are solid.”
The purpose of the open, public international scrutiny of the separate NIST algorithms is “to build trust and confidence,” he said.
I believe him. This is what the NSA did with NIST’s candidate algorithms for AES and then for SHA-3. NIST’s Post-Quantum Cryptography Standardization Process looks good.
I still worry about the long-term security of the submissions, though. In 2018, in an essay titled “ Cryptography After the Aliens Land ,” I wrote:
…there is always the possibility that those algorithms will fall to aliens with better quantum techniques. I am less worried about symmetric cryptography, where Grover’s algorithm is basically an upper limit on quantum improvements, than I am about public-key algorithms based on number theory, which feel more fragile. It’s possible that quantum computers will someday break all of them, even those that today are quantum resistant.
It took us a couple of decades to fully understand von Neumann computer architecture. I’m sure it will take years of working with a functional quantum computer to fully understand the limits of that architecture. And some things that we think of as computationally hard today will turn out not to be.
San Francisco police are using autonomous vehicles as mobile surveillance cameras.
Privacy advocates say the revelation that police are actively using AV footage is cause for alarm.
“This is very concerning,” Electronic Frontier Foundation (EFF) senior staff attorney Adam Schwartz told Motherboard. He said cars in general are troves of personal consumer data, but autonomous vehicles will have even more of that data from capturing the details of the world around them. “So when we see any police department identify AVs as a new source of evidence, that’s very concerning.”
ICE Is a Domestic Surveillance Agency
news.movim.eu / Schneier · Wednesday, 11 May - 14:24 · 1 minute
Georgetown has a new report on the highly secretive bulk surveillance activities of ICE in the US:
When you think about government surveillance in the United States, you likely think of the National Security Agency or the FBI. You might even think of a powerful police agency, such as the New York Police Department. But unless you or someone you love has been targeted for deportation, you probably don’t immediately think of Immigration and Customs Enforcement (ICE).
This report argues that you should. Our two-year investigation, including hundreds of Freedom of Information Act requests and a comprehensive review of ICE’s contracting and procurement records, reveals that ICE now operates as a domestic surveillance agency. Since its founding in 2003, ICE has not only been building its own capacity to use surveillance to carry out deportations but has also played a key role in the federal government’s larger push to amass as much information as possible about all of our lives. By reaching into the digital records of state and local governments and buying databases with billions of data points from private companies, ICE has created a surveillance infrastructure that enables it to pull detailed dossiers on nearly anyone, seemingly at any time. In its efforts to arrest and deport, ICE has — without any judicial, legislative or public oversight — reached into datasets containing personal information about the vast majority of people living in the U.S., whose records can end up in the hands of immigration enforcement simply because they apply for driver’s licenses; drive on the roads; or sign up with their local utilities to get access to heat, water and electricity.
ICE has built its dragnet surveillance system by crossing legal and ethical lines, leveraging the trust that people place in state agencies and essential service providers, and exploiting the vulnerability of people who volunteer their information to reunite with their families. Despite the incredible scope and evident civil rights implications of ICE’s surveillance practices, the agency has managed to shroud those practices in near-total secrecy, evading enforcement of even the handful of laws and policies that could be invoked to impose limitations. Federal and state lawmakers, for the most part, have yet to confront this reality.
