In a technical analysis of the UK NHSx contact tracing app for iOS, security engineers find that Apple's Bluetooth design makes it harder to detect iPhones running the app in background mode, and the app is using "keepalive" notifications in order to keep the app able to make the necessary connections. The researchers believe this workaround will work sufficiently well for users in populated areas. The app appears to abide by the privacy safeguards listed in the paper released by the National…

Academics have disclosed today a new vulnerability in the Bluetooth wireless protocol, broadly used to interconnect modern devices, such as smartphones, tablets, laptops, and smart IoT devices.
The vulnerability, codenamed BIAS (Bluetooth Impersonation AttackS), impacts the classic version of the Bluetooth protocol, also known as Basic Rate / Enhanced Data Rate, Bluetooth BR/EDR, or just Bluetooth Classic.
The BIAS attack
The BIAS security flaw resides in how devices handle the link key,…

“The BlueBorne attack vector requires no user interaction, is compatible to all software versions, and does not require any preconditions or configurations aside of the Bluetooth being active,” warned the researchers.
“Unlike the common misconception, Bluetooth enabled devices are constantly searching for incoming connections from any devices, and not only those they have been paired with,” they added.
“This means a Bluetooth connection can be established without pairing the devices at all.…

An engineering and computer science professor and his team from The Ohio State University discovered a design flaw in low-powered Bluetooth devices that leaves them susceptible to hacking.
Zhiqiang Lin, associate professor of computer science and engineering at the university, found the commonly used Bluetooth Low Energy devices, such as fitness trackers and smart speakers, are vulnerable when they communicate with their associated apps on the owner’s mobile phone.
"There is a fundamental…

On November 3rd, 2019, [...] a critical vulnerability affecting the Android Bluetooth subsystem [was reported]. This vulnerability has been assigned CVE-2020-0022 and was now patched in the latest security patch from February 2020. The security impact is as follows:
On Android 8.0 to 9.0, a remote attacker within proximity can silently execute arbitrary code with the privileges of the Bluetooth daemon as long as Bluetooth is enabled. No user interaction is required and only the Bluetooth MAC…

In February 2019 Google engineers announced that they had created faster, more efficient encryption system that could function on less-expensive Android phones that were too low-powered to implement existing full-device encryption. The scheme, known as Adiantum, uses established and well-vetted encryption tools and principles. Android has required smartphones to support encryption since 2015's version 6, but low-end devices were exempt because of the performance hit. It will now be up to device…

In December 2017, it was revealed that the large telco Bharti Airtel made use of Aadhaar-linked eKYC (electronic Know Your Customer) to open bank accounts for their customers without their knowledge or consent. eKYC is a way of using data in the UIDAI database as part of the verification process, which Airtel made use of for the issuing of SIM cards, and also secretly opened bank accounts with their Airtel Payments Bank. More than 2 million accounts could have been opened, receiving more than…

Background
Email is hard to secure. For years we've been trying to build security on top of email, such as through technologies like Pretty Good Privacy (PGP) and the open source implementation: GnuPG (GPG).
What happened
In the past 48 hours, there have been very scary looking reports recommending people switch off PGP in their email clients.
The TL;DR version of this post is:
PGP is not broken by this attack
You absolutely should not stop…

In 2015, US director of national intelligence James Clapper, backed by National Security Agency director Admiral Michael Rogers, warned Congress that the next phase of escalating online data theft is likely to involve manipulating digital information. Clapper and Rogers viewed this type of attack as more likely than a catastrophic event of digitally triggered damage to physical infrastructure. The pair believed that manipulating and deleting data would compromise data integrity and undermine…

For a period between the end of October and November 3 2016 the heating and hot water systems in two buildings in the city of Lappeenranta, Finland were knocked out by a distributed denial of service attack designed to make the systems fail. The systems responded by repeatedly rebooting the main control circuit, which meant that the heating was never working - at a time when temperatures had already dropped below freezing. Specialists in building maintenance noted that companies often skimp on…

A 2017 research report found that the most vulnerable smartphone users are the ones whose devices are most open to fraud and harassment. Cheaper, low-end devices are less secure to begin with, and they are also less often replaced than their more expensive counterparts made by. Apple and Google. At any given time there are millions of Android devices that are open to known exploits. Worse, the poorer population that owns these phones are more likely to use them as their sole means of accessing…

Even after they move out, domestic abusers may retain control over their former residence via Internet of Things devices and the mobile phone apps that control them. Using those tools, abusers can confuse, intimidate, and spy upon their former spouses and partners. Lack of knowledge about how these technologies work means that those who complain are often not taken seriously. Even the victims themselves may believe it's all in their minds; lawyers are struggling to develop language to add to…

In 2017, a website run by the Jharkhand Directorate of Social Security leaked the personal details of over.1 million Aadhaar subscribers, most of them old age pensioners who had enabled automatic benefits payment into their bank accounts. Aadhaar is a 12-digit unique identification number issued to all Indian residents based on their biometric and demographic data. Both cyber security agencies and the Supreme Court have expressed concerns over its security,…

There are three good reasons why security is so hard for NGOs. First, we are afraid to speak about meaningful security. Second, we focus on the wrong areas of security and in turn spend money and prioritise the wrong things. Third, we struggle to separate the world we want from the worlds we build within our own organisations. At PI we have failed and struggled with each of these for over 20 years. Out of exhaustion, we decided to do something about it: we are building an open framework, a…

This is the story of Privacy International's journey to building more secure services. Data collection and administering sensitive data on the open web is risky, and PI had to learn this the hard way.
Many companies say that the privacy of their audiences is their top priority. But do they mean it? Do they invest in it? Doing security on tight budgets is incredibly hard. But it is the natural state of the non-profit sector. We learned this through challenging experiences.…

The connectivity afforded by the internet has changed the world forever. While the increasing ‘corporatization’ of what many still feel is an open, non-hierarchical, largely uncensored and unfiltered ecosystem, this is increasingly not the case. The emergence of the ‘Internet of Things’ will soon throw into sharp relief who owns the internet and who owns the data we all generate when using the internet. Companies today have a vested interest in portraying their products as safe and…

Privacy can be seen as a reflex of innovation. One of the seminal pieces on the right to privacy as the 'right to be let alone emerged in response to the camera and its use by the tabloid media. Seminal jurisprudence is in response to new surveillance innovations... though often with significant delays.
While one approach would be to say that privacy is a norm and that with modern technologies the norm must be reconsidered and if necessary, abandoned; I think there’s an interesting idea around…
