Singing the Blues:
Taking Down an Insider Threat

"I had all of the advantages. I was already inside the network. No one suspected me. But they found my hack, kicked me off the network...

...and physically hunted me down."

Many pentests start from the outside, wanting to see how the perimeter might be breached.

This pentest started from the inside. My client wanted to assume they had already been breached, and, if breached, how far could an attacker go.

Could they stop me once I was inside?

So they snuck me in. Disguised me as a new employee. Gave me a work computer, an ID badge, an account in their system... hell, I even had a cubicle w/my assumed name on it.

The only person who knew who I really was was their CISO. Everyone else thought I was Jeremy in Marketing.

During most of the first morning, I completed onboarding, made introductions, and completed menial tasks.

But I had to act quick. I only had a week onsite. I had to hack their network while not raising suspicion.

So I set about it.

You have to understand... most "Internal Pentests" are straight forward. The hard part is breaching the network, but once you're inside, it's a target rich environment. End of Life computers, default passwords, everyone a Local Administrator...

Statue of Equality (Ramanuja) Muchintal, Hyderabad, Telangana

The Statue of Equality is a monument in India dedicated to the 11th-century Vaishnavaite Sage Bhagavad Ramanuja, commemorating 1000 years since his birth. It was inaugurated by Prime Minister Narendra Modi ji in 2019.

In 2014, Sri Chinna Jeeyar came up with the idea to commemorate the 1000th anniversary of Sri Ramanuja's teachings by building the Statue of Equality. The statue is constructed on an estimated 34 acres in Hyderabad, India.

It consists of a 216 foot tall statue of Ramanuja and is surrounded by 108 Divyadesams (model temples) and includes an educational gallery. The project budget is 1000 crore rupees.The foundation stone for the Statue of Equality was laid by Chinna Jeeyar.

The statue was built by Aerosun Corporation in China before being shipped to India. It is made of panchaloha, a combination of gold, silver, copper, brass and titanium. The statue relies on donations to fund its construction.

The temple is located on the 27,870 square metre second floor with a 120 kg statue of Ramanuja, representing the years he lived, meant for daily worship. The 1,365 square metre third floor including a Vedic digital library and research center.

1. Now that Stan Lee is being eulogized far and wide, it's important to remember how marginal Stan Lee and his collaborators (Jack Kirby and Steve Ditko) were in the 1950s and 1960s.

2. Marvel Comics (before that Atlas) was just a cog in the machine of a bottom pulp publisher run by Martin Goodman, the husband of one of Lee's cousins. It was the lowest of the low in the publishing world.

3. Now Mario Puzo (not yet the author of the Godfather) shared offices with Stan Lee in the 1950s and 1960s. Puzo wrote for garrish men's adventure magazines and, like Lee, dreamed of writing a novel & breaking out. But Puzo looked down on Lee.

4. Flo Steinberg, 1960s secretary at Marvel: "They were always making jokes about us. They'd come in and giggle. mario Puzo would look in and would see us all working on his way to the office and say, 'Work faster, little elves. Christmas is coming.'"

5. When JFK was killed, the whole office of Magazine Management was stunned and quiet. Except Lee. He continued working. "He was still working on the comic books," Puzo said. "Like that was the most important thing in the world."

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ

The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

A brief thread on Jovan Hutton Pulitzer, the crazy con man who is now claiming to have hacked into the Georgia voting machines in Fulton County. 90s kids and tech aficionados might remember Jovan as the inventor of the CueCat, the dumbest gadget of all time.

Also, for anyone who wants to claim that Jovan Hutton Pulitzer (not his given name, but one he changed legally after the CueCat debacle) invented QR Codes: he did not. Like that other right-wing crazy man who claimed to have invented email, Jovan didn’t invent QR Codes.

He did invent the CueCat, a product that somehow raised $185 million dollars for a tethered barcode scanner for magazines and newspapers, so you could get ads from your ads. As I said, the dumbest product of all time. Good backup barcode scanners after they were hacked, however

Oh, that’s another thing. When CueCat was a thing, its systems were hacked. I guess that’s what makes Jovan a security expert. His bankrupt company from 20 years ago was hacked and widely mocked. He’s a genius.

In recent years, Jovan pivoted to being a treasure hunter who was featured on and widely mocked on Curse of Oak Island, because the man is insane.
