Book Review: Countdown To Zero Day 58
benrothke writes A word to describe the book Takedown: The Pursuit and Capture of Americas Most Wanted Computer Outlaw was hyperbole. While the general storyline from the 1996 book was accurate, filler was written that created the legend of Kevin Mitnick. This in turn makes the book a near work of historical fiction. Much has changed in nearly 20 years and Countdown to Zero Day: Stuxnet and the Launch of the Worlds First Digital Weapon has certainly upped the ante for accurate computer security journalism. The book is a fascinating read and author Kim Zetters attention to detail and accuracy is superb. In the inside cover of the book, Kevin Mitnick describes this as an ambitious, comprehensive and engrossing book. The irony is not lost in that Mitnick was dogged by misrepresentations in Markoff's book. Keep reading for the rest of Ben's review.
For those that want to know the basics about Stuxnet, its Wikipedia entry will suffice. The book take a detailed look at how the Stuxnet worm of 2010 came to be, how it was written, discovered and deciphered, and what it means for the future and provides nearly everything known to date about Stuxnet. | Countdown to Zero Day: Stuxnet and the Launch of the Worlds First Digital Weapon | |

| summary | Outstanding narrative about Stuxnet and how it was developed, quarantined and debugged |
The need to create Stuxnet was the understanding that a nuclear Iran was dangerous to the world. The book notes that it just wasn't the US and Israel that wanted a nuclear free Iran; Egypt and Saudi Arabia were highly concerned about the dangers a nuclear Iran would bring to the region.
What is eminently clear is that Iran chronically lied about their nuclear intentions and actions (chapter 17 notes that former United Kingdom Prime Minister Gordon Brown told the international community that they had to do something over Iran's serial deception of many years) and that the United Nations International Atomic Energy Agency (IAEA) is powerless to do anything, save for monitoring and writing reports.
Just last week, President Obama said a big gap remains in international nuclear negotiations with Iran and he questioned whether talks would succeed. He further said "are we going to be able to close this final gap so that (Iran) can reenter the international community, sanctions can be slowly reduced and we have verifiable, lock tight assurances that they cant develop a nuclear weapon, there's still a big gap. We may not be able to get there". It's that backdrop to which Stuxnet was written.
While some may debate if Stuxnet was indeed the worlds first digital weapon, it's undeniable that it is the first piece of known malware that could be considered a cyber-weapon. Stuxnet was unlike any other previous malware. Rather than just hijacking targeted computers or stealing information from them, it created physical destruction on centrifuges the software controlled.
At just over 400 pages, the book is a bit wordy at times, but Zetter does a wonderful job of keeping the book extremely readable and the narrative enthralling. Writing about debugging virus code, Siemens industrial programmable logic controllers (PLC) and Step7 software (which was what Stuxnet was attacking) could easily be mind-numbingly boring, save for Zetter's ability to make it a compelling read.
While a good part of the book details the research Symantec, Kaspersky Lab and others did to debug Stuxnet, the book doesn't have any software code, which makes it readable for the non-programmer. The book is technical and Zetter gets into the elementary details of how Stuxnet operated; from reverse engineering, digital certificates and certificate authorities, cryptographic hashing and much more. The non-technical reader certainly won't be overwhelmed, but at the same time might not be able to appreciate what went into designing and making Stuxnet work.
As noted earlier, the book is extremely well researched and all significant claims are referenced. The book is heavily footnoted, which makes the book much more readable than the use of endnotes. Aside from the minor error of mistakenly calling Kurt Gödel a cryptographer on page 295, he was a logician; Zetter's painstaking attention to detail is to be commended.
Whoever wrote Stuxnet counted on the Iranians not having the skills to uncover or decipher the malicious attacks on their own. But as Zetter writes, they also didn't anticipate the crowdsourced wisdom of the hive — courtesy of the global cybersecurity community that would handle the detection and analysis for them. That detection and analysis spanned continents and numerous countries.
The book concludes with chapter 19 — Digital Pandora — which departs from the details of Stuxnet and gets into the bigger picture of what cyber-warfare means and its intended and unintended consequences. There are no simple answers here and the stakes are huge.
The chapter quotes Marcus Ranum who is outspoken on the topic of cyber-warfare. At the 2014 MISTI Infosec World Conference, Ranum gave a talk on Cyberwar: Putting Civilian Infrastructure on the Front Lines, Again. Be it the topic or Marcus just being Marcus, a third of the participants left within the first 15 minutes. But they should have stayed, as Ranum, agree with him or not, provided some riveting insights on the topic.
The book leaves two unresolved questions; who did it, and how did it get into the Nantanz enrichment facility. It is thought the US with some assistance from Israel created Stuxnet; but Zetter also writes that Germany and Great Britain may have done the work or at least provided assistance.
It's also unknown how Stuxnet got into the air-gapped facility. It was designed to spread via an infected USB flash drive. It's thought that since they couldn't get into the facility, what needed to be done was to infect computers belonging to a few outside firms that sold devices that would in turn be connected to the facility. The book identified a few of these companies, but it's still unclear if they were the ones, or the perpetrators somehow had someone on the inside.
As to zero day in the title, what was unique about Stuxnet is that it contained 5 zero day exploits. Zero day is also relevant in that Zetter describes the black and gray markets of firms that discover zero-day vulnerabilities who in turn sell them to law enforcement and intelligence agencies.
Creating Stuxnet was a huge challenge that took scores of programmers from a nation state many months to create. Writing a highly readable and engrossing book about the obscure software vulnerabilities that it exploited was also a challenge, albeit one that few authors could do efficaciously. In Countdown to Zero Day: Stuxnet and the Launch of the Worlds First Digital Weapon, Kim Zetter has written one of the best computer security narratives; a book you will likely find quite hard to put down.

Anything pointing out that the only substantial act of cyberwar was perpetrated by US/Israel supports terrorists, I guess. Can't let people actually have a discussion about it, have to bury it in a crapflood. Yeah, it's odd that this particular story has attracted such a storm of MyCleanPC and Bennet copypasta. What are the odds that it's actually a coincidence?
Free, Kevin Mitnick! (Score:3)
I remember when Mitnick was held in jail for 5 years by the FBI without a charge and that they were so scared of the guy they refused him a phone call because they believed he would be able to call in a nuclear bomb strike.
I read his book, "The Art of Deception" - an excellent read, yet despite all his recommendations we see all of the holes still present for the modern intelligencia to take advantage of. Kevin was to be the poster boy for 21st Century human rights abuse and the FBI didn't care how many bumper stickers people bought.
Huh? (Score:1)
I don't understand the point of the reference to Takedown, nor the irony of Mitnick commenting on another book.
