Australia Threatens to Force Companies to Break Encryption

In 2018, Australia passed the Assistance and Access Act, which—among other things—gave the government the power to force companies to break their own encryption.

The Assistance and Access Act includes key components that outline investigatory powers between government and industry. These components include:

  • Technical Assistance Requests (TARs): TARs are voluntary requests for assistance accessing encrypted data from law enforcement to teleco and technology companies. Companies are not legally obligated to comply with a TAR but law enforcement sends requests to solicit cooperation.
  • Technical Assistance Notices (TANs): TANS are compulsory notices (such as computer access warrants) that require companies to assist within their means with decrypting data or providing technical information that a law enforcement agency cannot access independently. Examples include certain source code, encryption, cryptography, and electronic hardware.
  • Technical Capability Notices (TCNs): TCNs are orders that require a company to build new capabilities that assist law enforcement agencies in accessing encrypted data. The Attorney-General must approve a TCN by confirming it is reasonable, proportionate, practical, and technically feasible.

It’s that final one that’s the real problem. The Australian government can force tech companies to build backdoors into their systems.

This is law, but near as anyone can tell the government has never used that third provision.

Now, the director of the Australian Security Intelligence Organisation (ASIO)—that’s basically their FBI or MI5—is threatening to do just that:

ASIO head, Mike Burgess, says he may soon use powers to compel tech companies to cooperate with warrants and unlock encrypted chats to aid in national security investigations.

[…]

But Mr Burgess says lawful access is all about targeted action against individuals under investigation.

“I understand there are people who really need it in some countries, but in this country, we’re subject to the rule of law, and if you’re doing nothing wrong, you’ve got privacy because no one’s looking at it,” Mr Burgess said.

“If there are suspicions, or we’ve got proof that we can justify you’re doing something wrong and you must be investigated, then actually we want lawful access to that data.”

Mr Burgess says tech companies could design apps in a way that allows law enforcement and security agencies access when they request it without comprising the integrity of encryption.

“I don’t accept that actually lawful access is a back door or systemic weakness, because that, in my mind, will be a bad design. I believe you can ­ these are clever people ­ design things that are secure, that give secure, lawful access,” he said.

We in the encryption space call that last one “nerd harder.” It, and the rest of his remarks, are the same tired talking points we’ve heard again and again.

It’s going to be an awfully big mess if Australia actually tries to make Apple, or Facebook’s WhatsApp, for that matter, break its own encryption for its “targeted actions” that put every other user at risk.

Security Researcher Sued for Disproving Government Statements

This story seems straightforward. A city is the victim of a ransomware attack. They repeatedly lie to the media about the severity of the breach. A security researcher repeatedly proves their statements to be lies. The city gets mad and sues the researcher.

Let’s hope the judge throws the case out, but—still—it will serve as a warning to others.

SQL Injection Attack on Airport Security

Interesting vulnerability:

…a special lane at airport security called Known Crewmember (KCM). KCM is a TSA program that allows pilots and flight attendants to bypass security screening, even when flying on domestic personal trips.

The KCM process is fairly simple: the employee uses the dedicated lane and presents their KCM barcode or provides the TSA agent their employee number and airline. Various forms of ID need to be presented while the TSA agent’s laptop verifies the employment status with the airline. If successful, the employee can access the sterile area without any screening at all.

A similar system also exists for cockpit access, called the Cockpit Access Security System (CASS). Most aircraft have at least one jumpseat inside the cockpit sitting behind the flying pilots. When pilots need to commute or travel, it is not always possible for them to occupy a revenue seat, so a jumpseat can be used instead. CASS allows the gate agent of a flight to verify that the jumpseater is an authorized pilot. The gate agent can then inform the crew of the flight that the jumpseater was authenticated by CASS.

[attack details omitted]

At this point, we realized we had discovered a very serious problem. Anyone with basic knowledge of SQL injection could login to this site and add anyone they wanted to KCM and CASS, allowing themselves to both skip security screening and then access the cockpits of commercial airliners.

We ended up finding several more serious issues but began the disclosure process immediately after finding the first issue.

Adm. Grace Hopper’s 1982 NSA Lecture Has Been Published

The “long lost lecture” by Adm. Grace Hopper has been published by the NSA. (Note that there are two parts.)

It’s a wonderful talk: funny, engaging, wise, prescient. Remember that talk was given in 1982, less than a year before the ARPANET switched to TCP/IP and the internet went operational. She was a remarkable person.

Listening to it, and thinking about the audience of NSA engineers, I wonder how much of what she’s talking about as the future of computing—miniaturization, parallelization—was being done in the present and in secret.
