Academics, security, and privacy researchers have proposed a new standard for the management of privacy policies and consumer rights.
The new standard is named privacy.txt and was inspired by similar solutions like robots.txt , security.txt , and ads.txt .
Just like the aforementioned, it is designed to be hosted in a website's root ( / ) or "/.well-known " directory and provide instructions to both users and automated systems about a company's privacy policies and user data controls.
The standard's authors say they designed privacy.txt as more countries are adopting stricter consumer privacy regulations and as the IT sector is developing tools for allowing users to manage their personal data online.
For example, a tool designed to remove a user's data from internet sites will be able to scan a website for the privacy.txt file, and use information provided there to tell an online service to delete that user's data.
According to a draft of the proposed standard, a privacy.txt file will provide information such as:
- Corporate information about the website owner;
- URLs where a site's privacy policy is available, either in a simple UTF8 text or other formats;
- A contact email address;
- Emails or URLs where users can request that their personal data be deleted;
- Emails or URLs where users can request that their profile be deleted;
- Emails or URLs where users can opt out of having their data shared with third parties;
- Emails or URLs where users can request that their personal data be deleted;
- Emails or URLs where users can opt out of receiving marketing materials;
- Controls to configure cookie disclosure policies.
Researchers hope the new file format will make it easier for consumers to take privacy actions, similar to one-click unsubscribe features present in modern-day newsletters and email services.
Privacy.txt will be submitted to the IETF and follow the normal internet standard approval process in the hopes of receiving a formal RFC and gaining broader adoption.
Breaches, hacks, and security incidents
London Drugs hack: Pharmacy chain London Drugs has closed its stores across Western Canada in the aftermath of a cyberattack.

Change Healthcare hack: UnitedHealth CEO Andrew Witty says hackers breached the network of its Change Healthcare subsidiary using stolen credentials for the company's Citrix web portal. In a written testimony [ PDF ] to be delivered later this week at a Senate hearing, Witty says Change Healthcare failed to enable MFA on the hacked Citrix account. The UnitedHealth CEO didn't mention the exploitation of any Citrix vulnerabilities. He also took credit for deciding to pay the hacker's ransom demand. The decision backfired after the leaders of the AlphV ransomware group stole the $22 million for themselves. This led the AlphV affiliate who carried out the attack to continue the extortion against Change Healthcare, seeking a new payment. The hearing will take place on May 1 and will be live-streamed on YouTube via the URL embedded below.
General tech and privacy
FCC fines US telcos: The US Federal Communications Commission has fined the US' four largest wireless carriers for selling customer location data without consent. The FCC has fined T-Mobile $80 million and AT&T with $57 million. It also fined Verizon $47 million and Sprint with $12 million. The fines are related to a 2018 New York Times article on Securus Technologies, a company that sold location data to US law enforcement.
QTS anti-ransomware protection: QNAP has released the first version of its NAS operating system that features an anti-ransomware feature. The feature is included in the OS Security Center. It works by constantly monitoring file operations for unusual activity. Once a possible attack is detected, it will act to block and back up the user's data. QNAP devices have been the target of several ransomware strains over the years, such as AgeLocker, Qlocker, DeadBolt, eCh0raix, Muhstik, and QSnatch.
Microsoft Trusted Signing: Microsoft has rolled out its new Trusted Signing service into public preview . Trusted Signing is a code-signing and timestamping service designed for software developers.

IPv4 prices go down: Prices for IPv4 addresses started to decline for the first time last year. Dutch internet registry SIDN says cloud providers appear to have played a major role in the IPv4 market slowdown. The organization says cloud companies secured IPv4 inventories in previous years and have exited the IPv4 market, causing demand and prices to go down. Other reasons also included the increase in IPv6 adoption (now at 45%) and the proliferation of better dual-stack technologies.
Government, politics, and policy
FTC expands breach notification rules to health apps: The US FTC has expanded its data breach reporting rules to cover the makers of healthcare apps. The updated rules will apply to fitness trackers, fertility apps, and similar technologies. App makers will have to notify regulators, consumers, and the public when they suffer a security breach or face similar fines to healthcare orgs. The new rules also apply to third-party service providers, which will have to notify healthcare orgs when their data is compromised. The new rules will go into effect 60 days after publication in the Federal Register.
Senators ask for FTC investigation of auto industry: Two US senators have urged the FTC to investigate automakers for their failure to safeguard user consumer location data. Sen. Ron Wyden and Edward Markey claim that automakers lied to their customers on how they respond to law enforcement requests for their car's location data. The two claim that most automakers provide data to law enforcement without a warrant, and they don't notify customers of the request. Earlier this year, the same two senators also asked the FTC to investigate automakers for deceptive privacy policies and illegal sale of user data to third parties. [ Read the full letter here/PDF ]

Cybercrime and threat intel
Vastaamo hacker sentenced: A judge has sentenced Finnish hacker Aleksanteri Kivimäki to 6 years and 3 months in prison. Kivimäki was found guilty of hacking the Vastaamo Psychotherapy Center, stealing medical records, and extorting the center and its patients. He leaked medical records on the dark web and sent ransom demands to 33,000 of the clinic's clients, asking for €200 from each. Kivimäki was detained in France last year while attempting to use a fake passport. His lawyer says they will appeal the sentence. The Vastaamo hack is considered one of the worst in the country's history due to the highly sensitive nature of the leaked information and the massive extortion campaign that followed.
