Google’s top hacker hunter explains why hacking groups get codenames

Published

on

For more than a decade, the cybersecurity industry has been assigning names to different hacking groups. Some of them, like Fancy Bear, have crossed over into the mainstream because of their prominent hacks and memorable names. Others are only known within the cybersecurity industry. 

Oftentimes, even industry insiders can’t keep track. In part, that’s because every company names hacking groups differently. That’s why there are resources like this one, which attempt to be a one-stop shop where cybersecurity professionals, government officials, policymakers, journalists, and the wider public can make sense of who is who. 

Last month, Google became the latest company to revamp its naming system for hacking groups.

Gone are the days APT1, APT41 or APT whatever number, which was the system adopted by Mandiant, once an independent security firm that’s now part of Google. Mandiant was the first to adopt a naming scheme.

From now on, Google’s system is relatively simple: A hacking group will have a first name that is memorable and random, and a second word whose initial indicates the country of origin: Castle for China, Ion for Iran, Neptune for North Korea, and Relic for Russia.

According to Shane Huntley, the chief technology officer of Google Threat Intelligence Group, the company’s in-house hacker hunting team, the revamp was necessary to bring clarity to security researchers both inside the company and externally. 

In the early 2010s, when companies started publishing reports on cyberattacks and naming the hackers behind them, Huntley told TechCrunch that, “we were not expecting to have as many threat groups as we do today.”

It had become hard to keep track of everyone. Google now tracks more than 5,000 “activity clusters” in several countries, according to John Hultquist, chief analyst at Google Threat Intelligence Group. Huntley said that there are very few developed nations that don’t have their own cyber capabilities and hacking groups.

But what is the point of naming hacking groups? It’s not just an academic exercise, Huntley explained. The goal is to have a baseline understanding of who is attacking who, and how they are attacking them. That way organizations can recognize threats more quickly, prepare against them, ideally stop them, or at least investigate incidents more promptly. 

All that, he said, it’s possible only if you name the hackers and track them consistently. 

“If you actually get hacked by them or you’re dealing with some incident, knowing how that actor behaves, what they do, what they’ve done in the past, all of these details become critically important to help the response and also work out your coverage against these threats as well,” said Huntley.

Knowing how the North Korean government hackers known as the Lazarus Group behaves, what their goals usually are, and who they work for, gives defenders a starting point in dealing with these hackers.

Tracking state-sponsored hackers, while challenging, is easier than tracking cybercriminal groups and hackers-for-hire, Huntley explained. The government hackers tend to have more consistent targets and activities, while cybercriminal groups have members that come and go, sometimes splinter, and otherwise are more amorphous. Hacker-for-hire groups and spyware makers tend to have a lot of customers in different parts of the world, making them slightly harder to track. 

A common criticism whenever a new naming system gets announced is: Why don’t all companies and organizations just use the same codenames? While that seems like an easy question to answer, the reality is that every company has a slightly different view of every group, based on their own sets of data and telemetry. Huntely said this is an inescapable reality that can’t be avoided just by sharing more information among companies and groups of researchers. 

“No one has perfect visibility,” he said. “We are building our model and our best understanding, but we will never know everything about what’s going on.”

By unifying the naming scheme of Google’s old Threat Analysis Group, which Huntely headed, and Mandiant, at least now there’s one fewer scheme to remember. For everything else, refer to this gargantuan list.

Investigation into whether staff improperly accessed Minnie Merriman’s file after she was named for the first time this week

A Scottish NHS trust is investigating a data breach concerning the medical records of a nine-year-old girl who died earlier this week and was named publicly for the first time on Wednesday after a man was charged with her death.

The alleged breach occurred at Ninewells Hospital in Dundee, and reportedly involved staff members accessing the girl’s medical records without authorization or clinical need.

A spokesperson for NHS Tayside, which oversees Ninewells Hospital, said: “NHS Tayside is currently investigating the circumstances of an alleged data breach which happened in a working clinical area where staff access patient information.

“As a matter of governance, any data protection breach would be recorded and investigated by NHS Tayside and, where appropriate, reported to the Information Commissioner’s Office (ICO). It would not be appropriate for us to comment further on individual staffing matters.”

NHS Tayside did not respond to questions about the nature of the accessed data nor who is thought to be behind the intrusion.

Medical records in the UK are protected by the UK GDPR, contained in the Data Protection Act 2018 as well as several common law confidentiality rules. NHS staff are only allowed to access patient information where there is a legitimate clinical or other work-related need.

A 35-year-old man whom police say was known to the child, was arrested and appeared in court on August 5 over the death of Minnie Merriman. 

The man issued no plea at Forfar Sheriff Court on the day of his arrest and has been remanded in custody.

Merriman was found in Elliot Industrial Estate at approximately 0002 on Monday, August 3, with serious injuries.

The young girl was then taken to Ninewells Hospital in Dundee, where she later died.

Police Scotland said that they are not currently looking for anyone else in connection with her death.

Other members of Merriman’s family, who are from West Yorkshire and were camping nearby, are being supported by specialists. 

A family statement, released through Police Scotland, read: “We are devastated with the loss of our beloved, absolutely incredible, beautiful and brave Minnie Moo. Our family asks that our privacy is respected at this extremely difficult time.”

Detective Inspector Mike Ness of Police Scotland’s major investigation team said: “Our thoughts remain with everyone affected by these events, especially Minnie’s family.

“A police presence will remain in the area while our enquiries continue.

“Anyone with any concerns, or information, should approach these officers or contact Police Scotland on 101, quoting incident number 0008 of Monday, 3 August 2026.” ®

Apple’s legal battles with Jon Prosser encounter new hurdles

Published

on

Jon Prosser was sued by Apple over the alleged theft of pre-release information, saw a default ruling due to inaction, had that overturned, and is once again failing to provide discovery materials. There’s a reason this time.

Life hasn’t been easy for Jon Prosser since a July 2025 lawsuit from Apple accused him and Michael Ramacciotti of stealing information from Apple employee Ethan Lipnik’s test device. He says he’s not guilty, but has created roadblocks at every possible point in this case.

According to a new filing, Jon Prosser has not been responding to requests for discovery since he rejoined the case in June. Apple last heard from Prosser’s counsel on July 6, 2026.

In the interim, Prosser had a second child. The lack of response is attributed to the newborn.

He allegedly hasn’t had time to provide requested materials. In the filing he says that he “will find dates when additional discovery may be provided to Apple.”

However, given the situation involves a newborn, Apple appears to be a little more understanding of this delay. The joint filing suggests that Apple has approved the delays in discovery and the new dates.

What isn’t clear is whether Apple will take a softer approach to the final determination and punishment for Prosser. The worst case here is that he is barred from reporting on Apple, which is a significant portion of his business.

A new deposition is set to take place in September 2026. The next legal filing is expected on October 7, 2026.

TP-Link Roam 7: 30-second review

The TP-Link Roam 7 is a compact travel router that lets you connect to whatever internet you can find and turns that into your own private network. This helps reduce the need to reconnect all your devices in each new location; just connect the router and all other devices will connect automatically through it.

The Roam 7 differs from a mobile router insofar as there’s no internal SIM or battery; power is supplied through a USB source such as a power bank, and the internet connection comes from a range of available options, including Ethernet at a hotel or business, public Wi-Fi, your phone tethered or a USB modem.

Cloudflare says humans could become a “rounding error” as bots generate 1,000 times more internet traffic

Published

on

Crystal ball: Just a couple of months after Cloudflare revealed that bots have officially surpassed human traffic online, the company has given its view on what things will look like in five years. It’s not good news for us fleshy meatsacks: non-human traffic could be up to 1,000 times higher than human traffic.

CDN and cybersecurity giant Cloudflare held its Q2 earnings call on Thursday, during which chief financial officer Thomas Seifert gave a concerning prediction about what the web will look like in the future.

“If the current trends continue, we think in five years, non-human traffic will be as much as 1,000 times as much as human traffic,” he said.

“In other words, humans will be a rounding error on the internet, not because human traffic goes down, but that’s just how fast we’re seeing non-human traffic grow.”

Advertisement

Seifert did add the important caveat that his predictions have been wrong in the past. Cloudflare CEO and co-founder Matthew Prince will likely be able to relate to this. He had predicted that bot traffic would surpass humans at the end of 2027, but it happened earlier this year.

Also read: The Zero Click Internet

It goes without saying that the sudden acceleration in non-human traffic is being driven by AI – agentic AI, specifically. Agentic systems behave very differently from traditional web crawlers and fraud bots. Their activity can closely resemble ordinary browsing, but it happens at machine speed and can be repeated on an enormous scale.

Even a straightforward prompt may trigger thousands of requests. Prince illustrated the difference using online shopping: someone searching for a camera might check five retailers, while an AI agent could examine 5,000 sites on their behalf. Multiply that behavior across millions of users asking assistants to compare products and airfares, research topics, collect information, or condense articles, and you can see why Seifert believes humanity’s online presence will become a rounding error.

Seifert said that if traffic does grow the way he expects, “we’ve got to get a lot more efficient,” which is where Cloudflare’s services come in, of course. He also mentioned the security implications of a web made up pretty much entirely of bots.

The idea that Dead Internet Theory – the concept that the internet is mostly run by bots and AI – will be demonstrably true in a few years (or now, arguably) is a concerning one. For a start, it could see the end of independent sites that have relied on the web’s business model since the 1990s.

There’s also the fact that an internet full of bots, AI slop, and privacy risks is making more people pull away from the online world. In our poll, 97% of people said the internet today was a hellscape compared to its early days, and it looks like things are only going to get worse.

Google Should Still Be Forced To Shed Chrome, Advocacy Group Argues

Published

on

“Google should be required to divest the Chrome browser, and prohibited from paying Apple to distribute Google’s search engine, the nonprofit advocacy group Public Knowledge argues in a new court filing,” MediaPost reports, citing a friend-of-the-court brief filed Tuesday in the D.C. Circuit Court of Appeals:

The group adds that “independent ownership” of Chrome “would open the distribution channel Google controls and allow Chrome to serve browser users when it makes privacy decisions and determines how to integrate search and (artificial intelligence)…”

In September 2025, [U.S. District Court Judge] Mehta issued a remedies order that requires Google to share some data about users’ searches with “qualified” competitors and to provide syndicated search results and ads to those competitors. The order also prohibits Google from entering into exclusive distribution contracts for Google Search, Chrome, Google Assistant and the Gemini app for six years, but allows the company to continue to make payments for search-ad revenue or distribution to Apple, Mozilla and others…
Google recently appealed Mehta’s order. The company argued in its written brief that it “prevailed in the marketplace fair and square,” adding that Apple and Mozilla “sensibly chose” Google as the default search engine “because it gave their users the best experience,” and because Apple and Mozilla would earn the most ad revenue through the deals. The [U.S.] Justice Department and states countered to the appellate court last week that the liability finding should stand, and also argued that Google should have been banned from paying Apple and Mozilla for placement as the default search engine on their browsers.

[Antitrust enforcers had originally asked the judge to order Google to divest Chrome, but he’s already rejected that request.] The government did not argue in its appellate papers that Google should be forced to sell Chrome. But Public Knowledge independently contends in its friend-of-the-court brief that divestiture would benefit consumers… “Divestiture would place those decisions with an institution whose success depends on serving browser users primarily….” The group is calling the appellate court’s attention to Google’s April 2025 decision to preserve tracking cookies — a reversal from its earlier plans to block third-party cookies by default. “Google is in the position of both deciding Chrome’s tracking rules while running the advertising business affected by them,” Public Knowledge writes. “An independent Chrome could make those decisions on behalf of users alone.”

Advertisement

But Firefox developer Mozilla filed its own friend-of-the-court brief Thursday warning Firefox could be forced to “exit the browser and browser engine markets” if it can’t receive payment from Google for distributing its search engine, according to a later report from MediaPost:

Federal and state antitrust enforcers recently asked the appellate court to reverse the portion of Mehta’s order that allows those payments to continue. But Mozilla counters in its new friend-of-the-court brief that Mehta’s decision regarding those payments was supported by the evidence –including a study it conducted concluding that its revenue would “decline dramatically” if forced to replace Google with Bing as Firefox’s default search engine…

Google is expected to file new arguments with the appellate court next month.

Qwen 3.8-Max and Claude Opus 5 show why raw benchmark scores don’t predict the bill

Published

on

Alibaba released Qwen 3.8-Max this week and marketed the preview as second only to Claude Fable 5 (their launch-day table was more equivocal: the model leads on one of 12 coding-agent rows). But an independent harness came close to the opposite conclusion: a benchmark run, apparently using the Preview version, put Qwen 3.8-Max’s best effort setting mid-pack, and its default setting last.

Both results are real and defensible. The gap between them is about token and time budgets, and that matters because those figures aren’t usually headline numbers. Alibaba’s footnotes give its coding numbers a five-hour timeout, and up to 12 hours per run on PaperBench. The independent harness, VulcanBench, allowed between 45 and 60 minutes of wall clock time. A time budget between five and 16 times larger on Alibaba’s side explains the huge difference in results.

It’s time to do two things to start accounting for these differences when choosing models. First, the metric to use is cost per successful task: total spend, including everything you spent on attempts that failed, divided by the tasks that actually passed your acceptance check. Second, you need to make time or token budgets an explicit part of your acceptance criteria, not a hidden detail.

Price per token has stopped predicting the bill

The comparison everyone published in Qwen 3.8-Max’s first week was a price comparison, because that was the only data available. It is not a cheap model. DeepSeek-V4-Flash-0731, which entered public API beta on July 31, lists at 14 cents per million input tokens and 28 cents output. Qwen 3.8-Max lists at $2 and $6. Kimi K3 sits at $3 and $15.

Advertisement

Those prices tell you less than they used to, for a reason specific to reasoning models like Qwen: getting to a result costs thinking tokens. A model that spends most of its token allowance on reasoning can reach a token cap before it writes the answer, giving you an empty result indistinguishable from a total failure at the cost of a full run.

Artificial Analysis has the cleanest published measurement of how this can affect real agent spend: running its Intelligence Index on DeepSeek-V4-Flash at maximum effort took 210 million output tokens against a class median of 100 million. Absolute cost stayed low anyway, because the tokens were so cheap. But verbosity costs time, not just money, and depending on your use case that can sink you.

What you need is a number that counts everything you spent, including the attempts that came back empty, against the tasks that actually got done in the time and token budget you specified. This is what a cost-per-success metric helps you see.

Your failure rate is partly a configuration setting

A run that produces a wrong answer and a run that runs out of budget are different events with different fixes. Almost no harness distinguishes them, and almost no leaderboard reports the split. I hit this building an agent benchmark of my own: the harness logged a failure and nothing about why, and I had to add the distinction myself. When you do separate them, budget exhaustion turns out to dominate.

Advertisement

Long-Horizon-Terminal-Bench, published in July, ran 17 frontier models across 46 tasks through a shared harness with one 90-minute attempt each. Timeouts accounted for 79% of unresolved runs, against 19% for agents that stopped on their own and 3% for harness errors. The authors are careful about what that does and does not mean: the timed-out runs were not close to finishing, with mean reward between 0.10 and 0.35, so you cannot assume more time would have resulted in success. But the lesson is: benchmarks are implicitly measuring time efficiency, whether or not they shout about that.

The clearest published example of the mechanism comes from VulcanBench, the same open-source harness behind the Qwen chart. In a report dated July 26, Claude Opus 5’s lowest-effort setting was its best, solving 20 of 23 tasks against 18 at high effort. The extra reasoning wasn’t useless: high effort returned the fewest wrong answers of any setting, one against three. It ran out of clock instead, and a timeout scores zero. Two of its three regressions were cutoffs on tasks that low effort solves, and given unlimited time on both it only ties its cheapest setting, at 3.1 times the cost.

That has a direct consequence for anyone building a routing ladder. The standard design escalates to more reasoning when a cheap attempt fails, on the assumption that the next rung is better and merely costs more. For a meaningful share of model and task combinations that assumption is wrong, and you pay the higher rung’s price to escalate into a timeout or hitting a cap.

Who is already measuring this

Several groups have landed on cost per successful task independently in the last few months, which is the strongest signal it’s becoming standard.

Advertisement

VulcanBench reports dollars per solved task as a headline column and has since its earliest reports. Long-Horizon-Terminal-Bench publishes per-task cost next to accuracy, and its most instructive row is GPT-5.4 at roughly $26 per task with a much lower pass rate than Grok 4.5 at about $11. TestEvo-Bench runs agents under a cost cap, and Claude Code’s test-generation score falls from 71% to 44% at the tighter cap.

Vendors are already on board with the idea of measuring per successful task. HubSpot moved its Breeze Customer Agent in April to 50 cents per resolved conversation, down from $1 per handled conversation. Zendesk bills per automated resolution. Fin charges 99 cents per outcome and bills only on end-to-end resolution.

What to change this week

  • Emit a failure reason on every agent run as a required field, with budget exhaustion, verifier failure and harness error as distinct values rather than one failure flag. Until you can separate a timeout from a wrong answer, your pass rate is measuring two things at once and you cannot tell which one to fix.

  • Compute cost per successful task per effort level, not just per model. Total spend including failed attempts, divided by tasks that passed your acceptance check. The ranking will not match the rate card, and the cheapest setting may well win.

  • Cap on tokens rather than wall clock unless latency is genuinely in your service level objective. A wall-clock cap scores your provider’s serving speed as model quality.

  • Check the default effort setting on everything you have deployed. Qwen 3.8-Max runs at its highest reasoning setting when the effort field is unset, and its highest setting was its worst performer in independent testing. A team that never touches that parameter is running the configuration that costs the most per solved task.

How To Get The Best Battery Life From Your Retro Handheld Game Console

Published

on

If your vintage gaming system eats through batteries in a hurry, this is for you.

Old-school gaming handhelds can be battery hogs. Whether it’s the original Game Boy’s four AA batteries or the Game Gear’s six, they tear through cells at a rate that makes modern consoles feel like luxuries. Here’s the easiest way to boost your battery setup on your old Nintendo, Sega or Atari portable.

For this guide, we’re focusing on the most popular battery-powered handhelds from the late ’80s through the early 2000s. Those would be Nintendo’s original Game Boy, Game Boy Color, Game Boy Pocket and Game Boy Advance, plus Sega’s Game Gear and the Atari Lynx.

Advertisement

The bottom line? Modern rechargeable batteries smooth much of the friction out of these retro handhelds. They save money, cut environmental waste and let you avoid the headaches that go along with disposable alkalines.

The right rechargeable batteries

For most people, a set of nickel-metal hydride (NiMH) rechargeable batteries is the way to go. They’re reliable, reusable and much cheaper over time than disposable alkalines.

Panasonic Eneloop is an Engadget staff favorite. It’s consistent and tends to hold up over time better than cheaper options. If you want to save a few bucks, IKEA LADDA is a good budget alternative. (Some have speculated that they’re rebranded Eneloops, but that isn’t confirmed.) Both are sold in the AA and AAA sizes you need for these systems.

Advertisement
  • Game Boy – 4 × AA
  • Game Boy Color – 2 × AA
  • Game Boy Pocket – 2 × AAA
  • Game Boy Advance – 2 × AA
  • Game Gear – 6 × AA
  • Atari Lynx – 6 × AA

Just keep in mind that the system’s battery indicators don’t always behave the same way with rechargeables. If the low-battery warning comes on, you may want to get in the habit of quickly saving your game to be safe.

As for how many batteries you need, a good rule of thumb is to buy two full sets. That way, you always have one in the handheld with another charged and ready to go.

One possible exception is modded retro handhelds, since things like brighter screens can run through batteries faster than the stock hardware. In that case, a third set could be in order. Some power-hungry or voltage-sensitive mods might work better with 1.5V rechargeable lithium batteries, although they tend to cost more than standard NiMH cells.

Advertisement

USB-C battery mods

Some models, including the original Game Boy, can be modded with USB-C rechargeable battery pack kits. These make the handheld feel more like a modern system, removing the annoyance of battery swaps. Some work with USB-C power banks, although not all support charge-and-play.

There are a few risks and downsides. For example, some USB-C battery mods don’t fully isolate the battery while charging. This can generate extra heat and make it less safe to play while charging. So, it’s worth checking user feedback and sticking with well-regarded mods if you go that route.

Apple continues to dominate premium smartphone market share

Published

on

For smartphones selling at over $600, Apple owns 65% of that market and grew 9% year over year in the first half of 2026. However, Chinese brands are making a dent in local market share.

Apple ships 23% of all smartphones sold globally and captures 49% of all profit. It’s a behemoth on its own, but when accounting for smartphones in the $600 plus range, it’s the clear leader in market share.

According to a report from Counterpoint Research, Apple captured 65% of the global premium smartphone market. It grew 9% year over year during the first half of 2026, though its market share is still down when compared to the 74% held in 2022.

The decline since 2022 can be attributed to the premium Chinese smartphone market growing in popularity. When a Chinese consumer is presented with an option between an iPhone and a smartphone from Huawei, Xiaomi, or Oppo, they choose the local brand.

That said, Apple still holds most of the market globally at 65% and Samsung at 19%. The other OEMs make up the remaining 16%.

Bar chart comparing premium smartphone market share: Apple dominates around two-thirds, Samsung about one-fifth, others under one-fifth across H1 2022, H1 2025, H1 2026, with overall premium share gradually increasing.

Apple holds onto 65% of premium market share even as the rest of the market increases prices. Image source: Counterpoint

The premium smartphone market grew 5% overall year over year for the first half of 2026 and makes up a record 29% of the global market. The global RAM shortage driving up prices has pushed more smartphones into the premium $600 plus segment and price hikes on lower-end models are driving customers to more premium models.

The report suggests these trends are why smartphone manufacturers are leaning further into financing options. Samsung recently launched its Galaxy Card while Apple has introduced Apple Upgrade.

Advertisement

Trade-in prices have also gone up, as was seen with Apple earlier Thursday. Everything is meant to entice customers holding onto their more expensive devices for longer to upgrade sooner in spite of price increases.

It’s going to be an interesting fall as everything seems to be creating quite the hurdle for Apple to overcome. iPhone 18 Pro sales could be limited by the RAM shortage and Apple reports that it’s already selling as many iPhone 17 models as it can make.

Demand won’t be the issue, but supply held back by global supply chain instability. Consumers may be feeling the impact of economic uncertainty, but that may not matter if financing options continue to be plentiful.

What Are The 5 Ps For Pilots And Why Are They So Important?

Published

on





Safely piloting an aircraft requires training, skills, and experience. Take the 1500-hour rule for pilots for example, which requires those seeking to be licensed in airline transport to achieve a certain number of hours performing flights in different scenarios, totaling 1,500 hours. Even then, there’s still a number of factors to keep in mind, especially when you’re the sole aviator behind the controls. It’s for this reason, practices like the 5 P checklist are recommended as part of a successful single-pilot crew resource management (SRM) system.

The 5 P checklist is comprised of plan, plane, pilot, passengers and programming. Each one of these categories exist in order to help manage the level of risk for each flight. While on its face, the 5 P checklist seems fairly self-explanatory, going through each one helps to provide a thorough means of preparation and readiness. This isn’t something reserved for new pilots either, as repetitious checklists help even seasoned aviators ensure they’ve covered everything.

Each part of the 5 P checklist explained

There should always be a plan in place, which takes into account specific aspects of the trip. Some things to consider include whether the destination airport has any of the runways shut down, alternate airports should a problem arise, current weather conditions, and contingencies in the event of an emergency.

Of course, the plane itself should also be subject to evaluation. Pilot’s must go through pre-flight checklists and consider the aircraft’s limitations versus the flight requirements. Double check that the plane is configured properly, such as the distribution of weight, which affects the aircraft’s center of gravity.

Pilots should be evaluating themselves as well, to ensure they aren’t contributing to risks. For example, a pilot’s health, mental state, and experience are crucial components of a safe journey. If a pilot has the flu, is highly fatigued or lacks specific knowledge relating to the flight, they can actively reduce the level of safety.

A pilot also can’t neglect their passengers, as this can lead to problems in the air. Explaining things like emergency procedures beforehand and what to anticipate during the flight can help limit risk and reduce stress in the passengers.

The last entry of the 5 P checklist is programming, which reminds a pilot to verify things like their route and navigation points in their GPS system. GPS is just one aspect of how pilots see at night, so it’s critical to verify the system is functioning properly.

Advertisement

The 5 P checklist is used throughout the flight

The 5 P checklist is something that’s employed not only before the flight, but throughout it as well. There are several different phases of a flight, and each one presents its own set of potential risks. Therefore, a pilot must reevaluate during each one of these phases, making choices to help reduce hazards and enhance safety.

These phases of a flight consist of pre-take off, navigating to the runway (taxiing), the plane lifting off the runway, gaining altitude, reaching cruising height for level flight, descending, and finally landing. During these phases some aviators employ procedures based off of FAA guidelines, like the 30/70 rule, which can make takeoffs safer.

Pilots don’t only rely on the 5 P checklist but also combines it with others like the PAVE checklist, which stands for the pilot in command, the aircraft, the environment, and any external pressures. So, if as a passenger you’ve ever wondered what the pilot is up to before and during a flight, it’s likely they’re running through some of these checklists among other responsibilities.
