Friday Squid Blogging: Squid Eating Maine Shrimp

Squid are eating Maine shrimp, causing a collapse of the ecosystem. This seems to be a result of climate change.

Maine’s shrimp fishery has been closed for nearly a decade since the stock’s collapse in 2013. Scientists are now saying a species of squid that came into the Gulf of Maine during a historic ocean heatwave the year before may have been a “major player” in the shrimp’s downturn.

In 2012, the Gulf of Maine experienced some of its warmest temperatures in decades. Within a couple of years, the cold-water-loving northern shrimp had rapidly declined and the fishery, a small but valued source of income for fishermen in the offseason, closed.

Anne Richards, a biologist at the Northeast Fisheries Science Center in Woods Hole, Massachusetts, and Margaret Hunter, a biologist with the Maine Department of Marine Resources, studied the collapse and found that it coincided with an influx of longfin squid, a major shrimp predator.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Nation-State Attacker of Telecommunications Networks

Someone has been hacking telecommunications networks around the world:

  • LightBasin (aka UNC1945) is an activity cluster that has been consistently targeting the telecommunications sector at a global scale since at least 2016, leveraging custom tools and an in-depth knowledge of telecommunications network architectures.
  • Recent findings highlight this cluster’s extensive knowledge of telecommunications protocols, including the emulation of these protocols to facilitate command and control (C2) and utilizing scanning/packet-capture tools to retrieve highly specific information from mobile communication infrastructure, such as subscriber information and call metadata.
  • The nature of the data targeted by the actor aligns with information likely to be of significant interest to signals intelligence organizations.
  • CrowdStrike Intelligence assesses that LightBasin is a targeted intrusion actor that will continue to target the telecommunications sector. This assessment is made with high confidence and is based on tactics, techniques and procedures (TTPs), target scope, and objectives exhibited by this activity cluster. There is currently not enough available evidence to link the cluster’s activity to a specific country-nexus.

Some relation to China is reported, but this is not a definitive attribution.

Problems with Multifactor Authentication

Roger Grimes on why multifactor authentication isn’t a panacea:

The first time I heard of this issue was from a Midwest CEO. His organization had been hit by ransomware to the tune of $10M. Operationally, they were still recovering nearly a year later. And, embarrassingly, it was his most trusted VP who let the attackers in. It turns out that the VP had approved over 10 different push-based messages for logins that he was not involved in. When the VP was asked why he approved logins for logins he was not actually doing, his response was, “They (IT) told me that I needed to click on Approve when the message appeared!”

And there you have it in a nutshell. The VP did not understand the importance (“the WHY”) of why it was so important to ONLY approve logins that they were participating in. Perhaps they were told this. But there is a good chance that IT, when implementinthe new push-based MFA, instructed them as to what they needed to do to successfully log in, but failed to mention what they needed to do when they were not logging in if the same message arrived. Most likely, IT assumed that anyone would naturally understand that it also meant not approving unexpected, unexplained logins. Did the end user get trained as to what to do when an unexpected login arrived? Were they told to click on “Deny” and to contact IT Help Desk to report the active intrusion?

Or was the person told the correct instructions for both approving and denying and it just did not take? We all have busy lives. We all have too much to do. Perhaps the importance of the last part of the instructions just did not sink in. We can think we hear and not really hear. We can hear and still not care.

Textbook Rental Scam

Here’s a story of someone who, with three compatriots, rented textbooks from Amazon and then sold them instead of returning them. They used gift cards and prepaid credit cards to buy the books, so there was no available balance when Amazon tried to charge them the buyout price for non-returned books. They also used various aliases and other tricks to bypass Amazon’s fifteen-book limit. In all, they stole 14,000 textbooks worth over $1.5 million.

The article doesn’t link to the indictment, so I don’t know how they were discovered.

Using Machine Learning to Guess PINs from Video

Researchers trained a machine-learning system on videos of people typing their PINs into ATMs:

By using three tries, which is typically the maximum allowed number of attempts before the card is withheld, the researchers reconstructed the correct sequence for 5-digit PINs 30% of the time, and reached 41% for 4-digit PINs.

This works even if the person is covering the pad with their hands.

The article doesn’t contain a link to the original research. If someone knows it, please put it in the comments.

Ransomware Attacks against Water Treatment Plants

According to a report from CISA last week, there were three ransomware attacks against water treatment plants last year.

WWS Sector cyber intrusions from 2019 to early 2021 include:

  • In August 2021, malicious cyber actors used Ghost variant ransomware against a California-based WWS facility. The ransomware variant had been in the system for about a month and was discovered when three supervisory control and data acquisition (SCADA) servers displayed a ransomware message.
  • In July 2021, cyber actors used remote access to introduce ZuCaNo ransomware onto a Maine-based WWS facility’s wastewater SCADA computer. The treatment system was run manually until the SCADA computer was restored using local control and more frequent operator rounds.
  • In March 2021, cyber actors used an unknown ransomware variant against a Nevada-based WWS facility. The ransomware affected the victim’s SCADA system and backup systems. The SCADA system provides visibility and monitoring but is not a full industrial control system (ICS).

The Missouri Governor Doesn’t Understand Responsible Disclosure

The Missouri governor wants to prosecute the reporter who discovered a security vulnerability in a state’s website, and then reported it to the state.

The newspaper agreed to hold off publishing any story while the department fixed the problem and protected the private information of teachers around the state.

[…]

According to the Post-Dispatch, one of its reporters discovered the flaw in a web application allowing the public to search teacher certifications and credentials. No private information was publicly visible, but teacher Social Security numbers were contained in HTML source code of the pages.

The state removed the search tool after being notified of the issue by the Post-Dispatch. It was unclear how long the Social Security numbers had been vulnerable.

[…]

Chris Vickery, a California-based data security expert, told The Independent that it appears the department of education was “publishing data that it shouldn’t have been publishing.

“That’s not a crime for the journalists discovering it,” he said. “Putting Social Security numbers within HTML, even if it’s ‘non-display rendering’ HTML, is a stupid thing for the Missouri website to do and is a type of boneheaded mistake that has been around since day one of the Internet. No exploit, hacking or vulnerability is involved here.”

In explaining how he hopes the reporter and news organization will be prosecuted, [Gov.] Parson pointed to a state statute defining the crime of tampering with computer data. Vickery said that statute wouldn’t work in this instance because of a recent decision by the U.S. Supreme Court in the case of Van Buren v. United States.

One hopes that someone will calm the governor down.

Brian Krebs has more.

Suing Infrastructure Companies for Copyright Violations

It’s a matter of going after those with deep pockets. From Wired:

Cloudflare was sued in November 2018 by Mon Cheri Bridals and Maggie Sottero Designs, two wedding dress manufacturers and sellers that alleged Cloudflare was guilty of contributory copyright infringement because it didn’t terminate services for websites that infringed on the dressmakers’ copyrighted designs….

[Judge] Chhabria noted that the dressmakers have been harmed “by the proliferation of counterfeit retailers that sell knock-off dresses using the plaintiffs’ copyrighted images” and that they have “gone after the infringers in a range of actions, but to no avail — every time a website is successfully shut down, a new one takes its place.” Chhabria continued, “In an effort to more effectively stamp out infringement, the plaintiffs now go after a service common to many of the infringers: Cloudflare. The plaintiffs claim that Cloudflare contributes to the underlying copyright infringement by providing infringers with caching, content delivery, and security services. Because a reasonable jury could not — at least on this record — conclude that Cloudflare materially contributes to the underlying copyright infringement, the plaintiffs’ motion for summary judgment is denied and Cloudflare’s motion for summary judgment is granted.”

I was an expert witness for Cloudflare in this case, basically explaining to the court how the service works.

Airline Passenger Mistakes Vintage Camera for a Bomb

I feel sorry for the accused:

The “security incident” that forced a New-York bound flight to make an emergency landing at LaGuardia Airport on Saturday turned out to be a misunderstanding — after an airline passenger mistook another traveler’s camera for a bomb, sources said Sunday.

American Airlines Flight 4817 from Indianapolis — operated by Republic Airways — made an emergency landing at LaGuardia just after 3 p.m., and authorities took a suspicious passenger into custody for several hours.

It turns out the would-be “bomber” was just a vintage camera aficionado and the woman who reported him made a mistake, sources said.

Why in the world was the passenger in custody for “several hours”? They didn’t do anything wrong.

Back in 2007, I called this the “war on the unexpected.” It’s why “see something, say something” doesn’t work. If you put amateurs in the front lines of security, don’t be surprised when you get amateur security. I have lots of examples.

The European Parliament Voted to Ban Remote Biometric Surveillance

It’s not actually banned in the EU yet — the legislative process is much more complicated than that — but it’s a step: a total ban on biometric mass surveillance.

To respect “privacy and human dignity,” MEPs said that EU lawmakers should pass a permanent ban on the automated recognition of individuals in public spaces, saying citizens should only be monitored when suspected of a crime.

The parliament has also called for a ban on the use of private facial recognition databases — such as the controversial AI system created by U.S. startup Clearview (also already in use by some police forces in Europe) — and said predictive policing based on behavioural data should also be outlawed.

MEPs also want to ban social scoring systems which seek to rate the trustworthiness of citizens based on their behaviour or personality.
