Critical Vulnerabilities in GPS Trackers

This is a dangerous vulnerability:

An assessment from security firm BitSight found six vulnerabilities in the Micodus MV720, a GPS tracker that sells for about $20 and is widely available. The researchers who performed the assessment believe the same critical vulnerabilities are present in other Micodus tracker models. The China-based manufacturer says 1.5 million of its tracking devices are deployed across 420,000 customers. BitSight found the device in use in 169 countries, with customers including governments, militaries, law enforcement agencies, and aerospace, shipping, and manufacturing companies.

BitSight discovered what it said were six “severe” vulnerabilities in the device that allow for a host of possible attacks. One flaw is the use of unencrypted HTTP communications that makes it possible for remote hackers to conduct adversary-in-the-middle attacks that intercept or change requests sent between the mobile application and supporting servers. Other vulnerabilities include a flawed authentication mechanism in the mobile app that can allow attackers to access the hardcoded key for locking down the trackers and the ability to use a custom IP address that makes it possible for hackers to monitor and control all communications to and from the device.

The security firm said it first contacted Micodus in September to notify company officials of the vulnerabilities. BitSight and CISA finally went public with the findings on Tuesday after trying for months to privately engage with the manufacturer. As of the time of writing, all of the vulnerabilities remain unpatched and unmitigated.

These are computers and computer vulnerabilities, but because the computers are attached to cars, the vulnerabilities become potentially life-threatening. CISA writes:

These vulnerabilities could impact access to a vehicle fuel supply, vehicle control, or allow locational surveillance of vehicles in which the device is installed.

I wouldn’t have buried “vehicle control” in the middle of that sentence.

Russia Creates Malware False-Flag App

The Russian hacking group Turla released an Android app that seems to aid Ukrainian hackers in their attacks against Russian networks. It’s actually malware, and provides information back to the Russians:

The hackers pretended to be a “community of free people around the world who are fighting russia’s aggression”—much like the IT Army. But the app they developed was actually malware. The hackers called it CyberAzov, in reference to the Azov Regiment or Battalion, a far-right group that has become part of Ukraine’s national guard. To add more credibility to the ruse they hosted the app on a domain “spoofing” the Azov Regiment: cyberazov[.]com.

[…]

The app actually didn’t DDoS anything, but was designed to map out and figure out who would want to use such an app to attack Russian websites, according to Huntely.

[…]

Google said the fake app wasn’t hosted on the Play Store, and that the number of installs “was miniscule.”

NSO Group’s Pegasus Spyware Used against Thailand Pro-Democracy Activists and Leaders

Yet another basic human rights violation, courtesy of NSO Group: Citizen Lab has the details:

Key Findings

  • We discovered an extensive espionage campaign targeting Thai pro-democracy protesters, and activists calling for reforms to the monarchy.
  • We forensically confirmed that at least 30 individuals were infected with NSO Group’s Pegasus spyware.
  • The observed infections took place between October 2020 and November 2021.
  • The ongoing investigation was triggered by notifications sent by Apple to Thai civil society members in November 2021. Following the notification, multiple recipients made contact with civil society groups, including the Citizen Lab.
  • The report describes the results of an ensuing collaborative investigation by the Citizen Lab, and Thai NGOs iLaw, and DigitalReach.
  • A sample of the victims was independently analyzed by Amnesty International’s Security Lab which confirms the methodology used to determine Pegasus infections.

[…]

NSO Group has denied any wrongdoing and maintains that its products are to be used “in a legal manner and according to court orders and the local law of each country.” This justification is problematic, given the presence of local laws that infringe on international human rights standards and the lack of judicial oversight, transparency, and accountability in governmental surveillance, which could result in abuses of power. In Thailand, for example, Section 112 of the Criminal Code (also known as the lèse-majesté law), which criminalizes defamation, insults, and threats to the Thai royal family, has been criticized for being “fundamentally incompatible with the right to freedom of expression,” while the amended Computer Crime Act opens the door to potential rights violations, as it “gives overly broad powers to the government to restrict free speech [and] enforce surveillance and censorship.” Both laws have been used in concert to prosecute lawyers and activists, some of whom were targeted with Pegasus.

More details. News articles.

A few months ago, Ronan Farrow wrote a really good article on NSO Group and its problems. The company was itself hacked in 2021.

L3Harris Corporation was looking to buy NSO Group, but dropped its bid after the Biden administration expressed concerns. The US government blacklisted NSO Group last year, and the company is even more toxic than it was as a result—and a mess internally.

In another story, the nephew of jailed Hotel Rwanda dissident was also hacked by Pegasus.

EDITED TO ADD (7/28): The House Intelligence Committee held hearings on what to do about this rogue industry. It’s important to remember that while NSO Group gets all the heat, there are many other companies that do the same thing.

John-Scott Railton at the hearing:

If NSO Group goes bankrupt tomorrow, there are other companies, perhaps seeded with U.S. venture capital, that will attempt to step in to fill the gap. As long as U.S. investors see the mercenary spyware industry as a growth market, the U.S. financial sector is poised to turbocharge the problem and set fire to our collective cybersecurity and privacy.

Facebook Is Now Encrypting Links to Prevent URL Stripping

Some sites, including Facebook, add parameters to the web address for tracking purposes. These parameters have no functionality that is relevant to the user, but sites rely on them to track users across pages and properties.

Mozilla introduced support for URL stripping in Firefox 102, which it launched in June 2022. Firefox removes tracking parameters from web addresses automatically, but only in private browsing mode or when the browser’s Tracking Protection feature is set to strict. Firefox users may enable URL stripping in all Firefox modes, but this requires manual configuration. Brave Browser strips known tracking parameters from web addresses as well.

Facebook has responded by encrypting the entire URL into a single ciphertext blob.

Since it is no longer possible to identify the tracking part of the web address, it is no longer possible to remove it from the address automatically. In other words: Facebook has the upper hand in regards to URL-based tracking at the time, and there is little that can be done about it short of finding a way to decrypt the information.

San Francisco Police Want Real-Time Access to Private Surveillance Cameras

Surely no one could have predicted this:

The new proposal—championed by Mayor London Breed after November’s wild weekend of orchestrated burglaries and theft in the San Francisco Bay Area—would authorize the police department to use non-city-owned security cameras and camera networks to live monitor “significant events with public safety concerns” and ongoing felony or misdemeanor violations.

Currently, the police can only request historical footage from private cameras related to specific times and locations, rather than blanket monitoring. Mayor Breed also complained the police can only use real-time feeds in emergencies involving “imminent danger of death or serious physical injury.”

If approved, the draft ordinance would also allow SFPD to collect historical video footage to help conduct criminal investigations and those related to officer misconduct. The draft law currently stands as the following, which indicates the cops can broadly ask for and/or get access to live real-time video streams:

The proposed Surveillance Technology Policy would authorize the Police Department to use surveillance cameras and surveillance camera networks owned, leased, managed, or operated by non-City entities to: (1) temporarily live monitor activity during exigent circumstances, significant events with public safety concerns, and investigations relating to active misdemeanor and felony violations; (2) gather and review historical video footage for the purposes of conducting a criminal investigation; and (3) gather and review historical video footage for the purposes of an internal investigation regarding officer misconduct.

New Browser De-anonymization Technique

Researchers have a new way to de-anonymize browser users, by correlating their behavior on one account with their behavior on another:

The findings, which NJIT researchers will present at the Usenix Security Symposium in Boston next month, show how an attacker who tricks someone into loading a malicious website can determine whether that visitor controls a particular public identifier, like an email address or social media account, thus linking the visitor to a piece of potentially personal data.

When you visit a website, the page can capture your IP address, but this doesn’t necessarily give the site owner enough information to individually identify you. Instead, the hack analyzes subtle features of a potential target’s browser activity to determine whether they are logged into an account for an array of services, from YouTube and Dropbox to Twitter, Facebook, TikTok, and more. Plus the attacks work against every major browser, including the anonymity-focused Tor Browser.

[…]

“Let’s say you have a forum for underground extremists or activists, and a law enforcement agency has covertly taken control of it,” Curtmola says. “They want to identify the users of this forum but can’t do this directly because the users use pseudonyms. But let’s say that the agency was able to also gather a list of Facebook accounts who are suspected to be users of this forum. They would now be able to correlate whoever visits the forum with a specific Facebook identity.”

Post-Roe Privacy

This is an excellent essay outlining the post-Roe privacy threat model. (Summary: period tracking apps are largely a red herring.)

Taken together, this means the primary digital threat for people who take abortion pills is the actual evidence of intention stored on your phone, in the form of texts, emails, and search/web history. Cynthia Conti-Cook’s incredible article “Surveilling the Digital Abortion Diary details what we know now about how digital evidence has been used to prosecute women who have been pregnant. That evidence includes search engine history, as in the case of the prosecution of Latice Fisher in Mississippi. As Conti-Cook says, Ms. Fisher “conduct[ed] internet searches, including how to induce a miscarriage, ‘buy abortion pills, mifepristone online, misoprostol online,’ and ‘buy misoprostol abortion pill online,'” and then purchased misoprostol online. Those searches were the evidence that she intentionally induced a miscarriage. Text messages are also often used in prosecutions, as they were in the prosecution of Purvi Patel, also discussed in Conti-Cook’s article.

These examples are why advice from reproductive access experts like Kate Bertash focuses on securing text messages (use Signal and auto-set messages to disappear) and securing search queries (use a privacy-focused web browser, and use DuckDuckGo or turn Google search history off). After someone alerts police, digital evidence has been used to corroborate or show intent. But so far, we have not seen digital evidence be a first port of call for prosecutors or cops looking for people who may have self-managed an abortion. We can be vigilant in looking for any indications that this policing practice may change, but we can also be careful to ensure we’re focusing on mitigating the risks we know are indeed already being used to prosecute abortion-seekers.

[…]

As we’ve discussed above, just tracking your period doesn’t necessarily put you at additional risk of prosecution, and would only be relevant should you both become (or be suspected of becoming) pregnant, and then become the target of an investigation. Period tracking is also extremely useful if you need to determine how pregnant you might be, especially if you need to evaluate the relative access and legal risks for your abortion options.

It’s important to remember that if an investigation occurs, information from period trackers is probably less legally relevant than other information from your phone.

Security Vulnerabilities in Honda’s Keyless Entry System

Honda vehicles from 2021 to 2022 are vulnerable to this attack:

On Thursday, a security researcher who goes by Kevin2600 published a technical report and videos on a vulnerability that he claims allows anyone armed with a simple hardware device to steal the code to unlock Honda vehicles. Kevin2600, who works for cybersecurity firm Star-V Lab, dubbed the attack RollingPWN.

[…]

In a phone call, Kevin2600 explained that the attack relies on a weakness that allows someone using a software defined radio—such as HackRF—to capture the code that the car owner uses to open the car, and then replay it so that the hacker can open the car as well. In some cases, he said, the attack can be performed from 30 meters (approximately 98 feet) away.

In the videos, Kevin2600 and his colleagues show how the attack works by unlocking different models of Honda cars with a device connected to a laptop.

The Honda models that Kevin2600 and his colleagues tested the attack on use a so-called rolling code mechanism, which means that­—in theory­—every time the car owner uses the keyfob, it sends a different code to open it. This should make it impossible to capture the code and use it again. But the researchers found that there is a flaw that allows them to roll back the codes and reuse old codes to open the car, Kevin2600 said.
