Easy Hacks on Telephone Entry Systems

Blast from the past. Here’s my Channel 2600 recording from the Next HOPE (2010):

Telephone entry systems are practically everywhere in the city. An investigation after a series of break-ins uncovered several shockingly simple bypass techniques currently used by criminals. This presentation explains how the common keypad box will grant full access to a building in under ten seconds using only basic tools. The presentation will also give details on a series of countermeasures that can significantly reduce the vulnerabilities.

How to abseil a 200 foot tree with 100 feet of rope

Get a longer rope.

Here is an amusing footnote from British special forces history. In short (pun not intended) there was a distinct shift from Orde Wingate’s 1940s self-reliant “long line” marches by “Chindits” into Burma, let alone F. Spencer Chapman‘s work in Malaysia… to the British SAS getting slightly “hung up” when parachuting in the 1950s:

Equipped with 100 feet of rope, the paratroopers would tie the rope to the tree and abseil down to the ground. The technique was first instigated in 1953. However, it was found that many trees were taller than 100 feet, so the amount of rope carried was doubled to 200 feet.

Perhaps the rank incompetence of the Colonial Office (e.g. Sir Shenton Thomas’ retreat) was foreshadowing?

Whitehall bungling and incompetence leading directly to the fall of Singapore in 1942 has been disclosed for the first time by Whitehall officials. Papers relating to the wartime defence of Malaya and Singapore were considered so sensitive that they have been withheld from public inspection for 50 years – 20 years beyond the normal release date for official files. But the newly published government papers confirm that British efforts to scapegoat Australian forces and the Governor of the Straits Settlements for the most humiliating debacle in the history of the Empire could well have been motivated by a wish to deflect attention from Whitehall’s far greater dereliction of duty.

A need for better knowledge of the environment and risks seems like exactly what the British military should have taken from WWII; as Chapman himself published details in his 1949 public memoir…

1st Edition. Hardcover published 1949 in New York by W. W. Norton & Company

Yet somehow someone in the 1950s didn’t bother to check in with Chapman, let alone the height of trees before jumping into them, especially after at least a decade of prior military missions run beneath them?

This 97.58m tree is 120 feet too tall for a 200 foot rope
To be fair, a 300 foot tall Yellow Maranti stands out

Speaking of being bad at estimating environment/size, I’m reminded of a Delta memoir that made some obvious cultural errors.

Illustrations of Accuracy vs Precision and Bias

I find the six-sigma “bullseye” illustration of the accuracy vs precision problem… somewhat imprecise.

Source: “Experimental Designs for Next Generation Phenotyping”, January 2015, DOI:10.1007/978-3-319-13677-6_2
  • (a) Not Accurate, Not Precise
  • (b) Accurate, Not Precise
  • (c) Not Accurate, Precise
  • (d) Accurate, Precise

While it’s accurate to say that a bullseye illustrates the precise problem, surely there are more precise ways of illustrating overall the accuracy problem.

I mean there are so many “quality” applications other than trying to narrow everything to a point in order to shoot or bomb it — the obvious reference of a cross-hatch.

LiDar to the rescue! I found the following vendor diagram very refreshing as it relates to big data security controls.

Ok, maybe that’s still an illustration of targeting… by an over-the-horizon drone strike meant to eliminate an entire building. *Sigh*

My only real complaint though for this kind of superior illustration is that red/green are biased, subject to colorblindness. Was it too hard for them to use the word “not”?

New UK “Ranger Regiment” to “match brainpower with firepower”

The key takeaway from UK news about their Ranger Regiment design is that they’re claiming a need to move from training/advisory to “expeditionary” roles that go into the field with the forces they’re training.

Training, advising and accompanying partner forces dealing with extremist organizations and hostile state threats… creation of land regional hubs in Oman, Kenya, Germany and Belize…

General Sir Mark Carleton-Smith, Chief of the General Staff, actually has the money quote:

…all army capability, matching brainpower with firepower, data and software with hardware. …if you actually want to guarantee tactical success, you’re much better placed operating alongside those troops you’ve actually been responsible for generating and training in the first place.

Matching software with hardware seems… more like standard operating procedure than specialized. Likewise, was firepower being sent into field without any brainpower? And does that sound like training actually had been taking place at all?

I found a message from 1994 (Army Communicator, Vol 19, No 2) by Robert E. Gray, Major General, U.S. Army Commanding, which used similar language in a bitter form of farewell/warning.

It is a myth that technology is an operational panacea and thus requires fewer people to get the job done. Rather, budget constraints and technology require innovative people doing things smarter… We will endure reductions in training, and field units will have to pick up the ball. Also, some technology enhancements will be slow in reaching the field. Despite all these factors, no country in the world can match our might — whether it’s firepower, technology, or brain power.

“Field units will have to pick up the ball” of 1994 sounds eerily like General Carleton-Smith today, no?

Perhaps even more interesting is what was called an “uncomplimentary view of the US military noted by a retired Army officer” (James Mrazek, “The Art of Winning Wars” 1968, p. 53), as cited in “Strategymaking for the 1980s” by Lieutenant General Raymond B. Furlong, US Air Force (Parameters, Journal of the US Army War College, Volume 9, Issue 1, 1979, p. 9)

Except for our first two wars, an overwhelming abundance of economic power has been the deciding factor that has given the United States Army its victories. America has been inclined to rely on raw strength to the neglect of brains.

When you really get into reading Mrazek, you have to wonder why he didn’t call his 1968 thesis the war of art…

The impotence of the American juggernaut in Vietnam has put this problem under the spotlight of history. The one thing the guerrillas have in abundance is imagination, and this seems to outweigh the imbalance in materiel. It is the author’s contention that creativity is what wins battles–the same faculty that inspires great art.

Anyway, back to the 2021 UK message details, their stated move from training to an expeditionary approach signals to me planners admitting failure or obscuring harsh reality by trying to rebrand it as a new opportunity (far more than actually taking a move towards “guarantee” of any success).

It’s almost like when the power of money and technology fails to deliver, there’s a tendency of those charged with power management to grasp longingly at mysticism for solutions — as if art comes from divine inspiration, an individual appeal towards ultimate power, instead of being the expression of collective wisdom and collaboration (inverse to conflict).

Unfortunately, this announcement very much reminds me of an intentional lack of UK intelligence — how under reported SAS history has been (not to mention the role of US Vietnam War veterans), given who actually was sending expeditionary forces into the disastrous killing fields of Rhodesia.

I mean in reality will this really be anything more than a new chapter for the infamous “ace of spades“, or more than a return to the 101 of special forces (roots planted in WWII by the “long lines” of an “expeditionary” Wingate)?
