Nigerian Prison Break

There was a massive prison break in Abuja, Nigeria:

Armed with bombs, Rocket Propelled Grenade (RPGs) and General Purpose Machine Guns (GPMG), the attackers, who arrived at about 10:05 p.m. local time, gained access through the back of the prison, using dynamites to destroy the heavily fortified facility, freeing 600 out of the prison’s 994 inmates, according to the country’s defense minister, Bashir Magashi….

What’s interesting to me is how the defenders got the threat model wrong. That attack isn’t normally associated with a prison break; it sounds more like a military action in a civil war.

Ubiquitous Surveillance by ICE

Report by Georgetown’s Center on Privacy and Technology published a comprehensive report on the surprising amount of mass surveillance conducted by Immigration and Customs Enforcement (ICE).

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.

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

NIST’s post-quantum computing cryptography standard process is entering its final phases. It announced the first four algorithms:

For general encryption, used when we access secure websites, NIST has selected the CRYSTALS-Kyber algorithm. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation.

For digital signatures, often used when we need to verify identities during a digital transaction or to sign a document remotely, NIST has selected the three algorithms CRYSTALS-Dilithium, FALCON and SPHINCS+ (read as “Sphincs plus”). Reviewers noted the high efficiency of the first two, and NIST recommends CRYSTALS-Dilithium as the primary algorithm, with FALCON for applications that need smaller signatures than Dilithium can provide. The third, SPHINCS+, is somewhat larger and slower than the other two, but it is valuable as a backup for one chief reason: It is based on a different math approach than all three of NIST’s other selections.

NIST has not chosen a public-key encryption standard. The remaining candidates are BIKE, Classic McEliece, HQC, and SIKE.

I have a lot to say on this process, and have written an essay for IEEE Security & Privacy about it. It will be published in a month or so.

ZuoRAT Malware Is Targeting Routers

Wired is reporting on a new remote-access Trojan that is able to infect at least eighty different targets:

So far, researchers from Lumen Technologies’ Black Lotus Labs say they’ve identified at least 80 targets infected by the stealthy malware, including routers made by Cisco, Netgear, Asus, and DrayTek. Dubbed ZuoRAT, the remote access Trojan is part of a broader hacking campaign that has existed since at least the fourth quarter of 2020 and continues to operate.

The discovery of custom-built malware written for the MIPS architecture and compiled for small-office and home-office routers is significant, particularly given its range of capabilities. Its ability to enumerate all devices connected to an infected router and collect the DNS lookups and network traffic they send and receive and remain undetected is the hallmark of a highly sophisticated threat actor.

More details in the article.

Ecuador’s Attempt to Resettle Edward Snowden

Someone hacked the Ecuadorian embassy in Moscow and found a document related to Ecuador’s 2013 efforts to bring Edward Snowden there. If you remember, Snowden was traveling from Hong Kong to somewhere when the US revoked his passport, stranding him in Russia. In the document, Ecuador asks Russia to provide Snowden with safe passage to come to Ecuador.

It’s hard to believe this all happened almost ten years ago.

When Security Locks You Out of Everything

Thought experiment story of someone who lost everything in a house fire, and now can’t log into anything:

But to get into my cloud, I need my password and 2FA. And even if I could convince the cloud provider to bypass that and let me in, the backup is secured with a password which is stored in—you guessed it—my Password Manager.

I am in cyclic dependency hell. To get my passwords, I need my 2FA. To get my 2FA, I need my passwords.

It’s a one-in-a-million story, and one that’s hard to take into account in system design.

This is where we reach the limits of the “Code Is Law” movement.

In the boring analogue world—I am pretty sure that I’d be able to convince a human that I am who I say I am. And, thus, get access to my accounts. I may have to go to court to force a company to give me access back, but it is possible.

But when things are secured by an unassailable algorithm—I am out of luck. No amount of pleading will let me without the correct credentials. The company which provides my password manager simply doesn’t have access to my passwords. There is no-one to convince. Code is law.

Of course, if I can wangle my way past security, an evil-doer could also do so.

So which is the bigger risk?

  • An impersonator who convinces a service provider that they are me?
  • A malicious insider who works for a service provider?
  • Me permanently losing access to all of my identifiers?

I don’t know the answer to that.

Those risks are in the order of most common to least common, but that doesn’t necessarily mean that they are in risk order. They probably are, but then we’re left with no good way to handle someone who has lost all their digital credentials—computer, phone, backup, hardware token, wallet with ID cards—in a catastrophic house fire.

I want to remind readers that this isn’t a true story. It didn’t actually happen. It’s a thought experiment.
