Turns out Lenovo preloaded their laptops with adware that will intercept all your secure connections, and allow criminals to do it, too.

After investigating the Lenovo incident we found out that many other softwares – like some Parental Controls or security packages – do things even worse for your security. This test attempts to detect them all.

U.S. Tech Companies Press Case Against Restrictive Chinese Rules | WSJ

The proposed restrictions are the latest sign of the continuing repercussions from information about U.S. government intelligence-gathering tactics leaked by Edward Snowden, a former contractor for the National Security Agency. Among other things, Mr. Snowden alleged U.S. authorities hacked millions of Chinese phone messages.

China has issued restrictions that so far affect the country’s banking sector, but officials there have said they are under review and may be extended to telecommunication and other sectors, according to the letter.

China’s New Rules Ask Tech Firms to Hand Over Source Code | IEEE Spectrum

New Rules in China Upset Western Tech Companies | NYTimes.com

The Chinese government has adopted new regulations requiring companies that sell computer equipment to Chinese banks to turn over secret source code, submit to invasive audits and build so-called back doors into hardware and software, according to a copy of the rules obtained by foreign technology companies that do billions of dollars’ worth of business in China.

Some of America’s largest tech companies could be hurt by the rules, including Apple, which is making a big push into the country. Apple has used new encryption methods in the iPhone 6 that are based on a complicated mathematical algorithm tied to a code unique to each phone. Apple says it has no access to the codes, but under the proposed antiterrorism law, it would be required to provide a key so that the Chinese government could decrypt data stored on iPhones.

[Wikileaks が明らかにした FinFisher:The Verge


A Spy in the Machine | The Verge

One day in 2011, Moosa opened the Facebook Messenger app on his iPhone. What he saw was chilling: someone else typing under his name to an activist friend of his in Bahrain…

Facebook was only the beginning. Unbeknownst to him, Moosa’s phone and computer had been infected with a highly sophisticated piece of spyware, built and sold in secret.

It was a sign of a more sophisticated author at work. The implant used a technique called process-hollowing — injecting its own code into a program that’s still running in order to use the legitimate program as cover. […] “I thought, Finspy, that rings some bells,” Marquis-Boire recalls. “Holy shit, I think this is FinFisher!”

FinFisher had become a kind of bogeyman in the security community since brochures advertising the software’s capabilities popped up in a Wikileaks drop in December of 2011. FinFisher could purportedly empower its owner with the kinds of advanced intrusion techniques usually reserved for the NSA. “There was a certain amount of interest just because no one had seen it,” Marquis-Boire says. “All we had were these leaked documents.”

FinFisher was created and sold by Gamma International, an international surveillance company with offices in London and Frankfurt. The Gamma brochures promised remote monitoring and keylogging — they even said they could listen in on a target’s Skype calls in real time.

But now Marquis-Boire had caught a FinFisher sample in the wild, and thanks to the leaked brochures, he had a roadmap of everything the implant could do.

Marquis-Boire enlisted the aid of Claudio Guarnieri, a researcher at security firm Rapid7, to further explore the software. The two uncovered a mobile version of the implant, which came in different versions for iOS, Android, and even Symbian, like a hot startup trying to cover as much of the market as possible. […] Once the implant was installed, your phone effectively became an enemy agent. “I’d be working at my computer and start squinting at my phone, thinking, maybe I should turn that off,” Marquis-Boire says. “It produced this weird dissonance between me and this device that I carry around all the time.”

Instead of a few outposts, they found an army. FinFisher’s agents were everywhere: Japan, Germany, India, Serbia, Mongolia — there were even servers in the US. It was an atlas of personal invasions. All told, 25 countries hosted a server of some kind, each hired out to a different regime and pointing the x-ray at a different enemy of the state.

Marquis-Boire published the work in a series of three landmark papers from July 2012 to March of 2013, each titled with a cheeky Bond pun like 
”The Smartphone Who Loved Me” or “You Only Click Twice.” The papers laid out everything he knew about FinFisher’s network, revealing a global surveillance network that was being hired out to some of the world’s most repressive governments. Targeted exploits weren’t just for the NSA anymore. They were available to anyone who could pay for them.

Once the papers were published, FinFisher went back underground. The coders behind the program began to change its routines and filenames enough to let it slip by unnoticed.

Their primary concern stems not from what effect FinFisher could have on their activism, but from the specter of having their personal lives invaded — the same fundamental privacy concern behind much of the NSA surveillance controversies in the US.

“They actually have a system that the government buys, and they get the whole package,” Marczak says. “It’s not just the code itself, it’s the administration, the analysis, the support — the whole framework is provided.”

That turns the same surveillance conducted by the NSA or GCHQ into a market product, available to the highest bidder with no questions asked. “The value proposition is essentially: ‘Activists in your country are giving you trouble? Well here’s a product that will allow you to turn their cellphone or computer into basically a wiretap, a surveillance tool, and you can spy on everything they do,’” Marczak says. “And I think governments are very attracted to that.”

「ネットセキュリティ評価」(security audits、安全审查)というのが何を意味するのかよく分からないが、少し前に読んだある記事のことを思い出した。

NSA[米国家安全保障局]による個人情報収集の手口を告発した元局員 Edward Snowden[エドワード・スノーデン]に関するものだ。

ロシアに滞在中の Snowden が iPhone について次のように語ったという。彼の弁護士 Anatoly Kucherena が Sputnik に明らかにしたものだ。

iPhone には特別なソフト

「Edward Snowden は決して iPhone を使わなかった。持っていたのは簡単な電話だった・・・。 iPhone には特別なソフトがあって、持ち主が起動してボタンを押さなくても、(遠隔から)持ち主に関する情報を収集できる。だからセキュリティ上の理由で彼は iPhone を使わなかったのだ」と Anatoly Kucherena は RIA Novosti に語った。

“Edward never uses an IPhone, he’s got a simple phone… The iPhone has special software that can activate itself without the owner, having to press a button and gather information about him, that’s why on security grounds he refused to have this phone,” Anatoly Kucherena told RIA Novosti.

     *     *     *

司法機関といえども iPhone から個人情報を抽出するのは困難だと信じてきたので、そんな遠隔監視ソフトが iPhone にあるなんてまったくの初耳だった。


そういえば、Snowden が携帯電話のことを非常に警戒した話はよく知られている。

まるでスパイ小説のようだった。Snowden 氏は野球帽をかぶり、サングラスをかけていた。そして集まった弁護士たちに香港の隠れ家の冷蔵庫に携帯電話を入れるようしつこく迫った。いかなる盗聴といえども防ぐためだ。そして2時間の話し合いが始まった・・・

It was a cloak-and-dagger affair. Mr. Snowden wore a cap and sunglasses and insisted that the assembled lawyers hide their cellphones in the refrigerator of the home where he was staying, to block any eavesdropping. […]

もっとも彼に他国への亡命を思いとどまらせてロシアの滞在許可をとるよう説得したのが弁護士 Anatoly Kucherena であり、また彼はクレムリンとの密接な関係をウワサされる人物でもあるところからますますスパイ小説じみてくるのだが・・・

Disable Remote Content to Fight Spam and Guard Your Privacy | TekRevue

If you even open a spammer’s email that contains images, the spammer instantly knows that your email address is valid and that you saw the spam email. Even worse, the spammer will also be able to learn important information about you, such as your IP address, which for most users reveals their general geographic location.

Launch Mail in OS X and go to Mail > Preferences > Viewing. Find the box labeled Load remote content in messages and uncheck it. This stops Mail from automatically loading images and other remote content when you first open an email message.

Your Mac’s Firewall is Off By Default: Do You Need to Enable It? | How-To Geek

A standard Mac OS X system doesn’t have such potentially vulnerable services listening by default, so it doesn’t need a tacked-on firewall to help protect such vulnerable services from being attacked.

This is actually the same reason why Ubuntu Linux doesn’t ship with its firewall on by default — another thing that was controversial at the time. Ubuntu took the approach of simply not having potentially vulnerable services listening by default, so an Ubuntu system is secure without a firewall. Mac OS X works in the same way.

Update:続報 — Android は安全だ》


[Android とマルウェア:image

Sundar Pichai の非常に率直な発言が話題になっている。

スペインのバルセロナで開催されている Mobile World Congress で、グーグルの Android チームを率いる Sundar Pichai が Android の安全性について答えたものだ。(Pichai は Andy Rubin の後を継いで Android の責任者となった。)

Pichai の発言の内容はつぎのとおり。

9to5Mac: “Google’s Sundar Pichai: Android not designed to be safe, would target Android too if he were making malware” by Ben Lovejoy: 27 February 2014
FrAndroid: “Pour Sundar Pichai, ‘le Galaxy S6 sera sous Android’” by Ulrich Rozier: 27 February 2014

Android の安全性は保証できない

Android の安全性が確実であるように設計されているとは保証できない。むしろ Android は自由度を与えるべく設計されているからだ。Android を対象とするマルウェアの9割を話題にするとき、これは世界で最もポピュラーな OS への攻撃であることに思いをいたすべきだ。もし自分がマルウェア製作に専念する会社を持っているとしたら、当然自分は Android を攻撃目標にするだろう[と彼は笑いながら答えた。]

[9to5Mac の英訳]
We cannot guarantee that Android is designed to be safe, the format was designed to give more freedom. When people talk about 90% of malware for Android, they must of course take into account the fact that it is the most popular operating system in the world. If I had a company dedicated to malware, I would also be addressing my attacks on Android.

[FrAndroid の原文]
« Nous ne pouvons garantir que Android est conçu pour être sûr, son format a été conçu pour donner plus de liberté. Quand ils parlent de 90 % des logiciels malveillants destinés à Android, ils doivent bien entendu tenir compte du fait que c’est le système d’exploitation le plus utilisé dans le monde. Si j’avais une entreprise dédiée aux logiciels malveillants, j’adresserais également mes attaques à Android« , a t-il déclaré avec un grand sourire.

     *     *     *


また、FrAndroid のフランス語を 9to5Mac が(グーグル翻訳で)直訳しているように見えることから、発言の際のニュアンスも不明だ。

しかし OS の安全性が問題になっている折から、あからさまともいえるその「率直さ」が注目を引いた。

古い Windows 時代の言い草だ。Android がポピュラーだから当然マルウェアもたくさんあるのだと。しかしある意味サードパーティの開発者のサポートという点で、唯一 Android が iOS に差をつけている点だ。

The old Windows line of defense: Android is so popular of course it has all the malware. For some reason, though, that’s the only sort of software where Android leads iOS in third-party developer support.

《Update》続報 — Android は安全だ(3月1日)


[Sundar Pichai:photo

FrAndroid の記事で第一報を伝えた Mashable が、グーグルの提供したトランスクリプトを基に、Sundar Pichai の発言内容を訂正している。

Android は安全ではないとはひとこともいっていない、と・・・

Mashable: “Google’s Sundar Pichai: Android Built to Be Secure [UPDATED]” by Karissa Bell: 27 February 2014

     *     *     *


Android は非常に、大変安全に作られている。あなたがそう見るのは、Android がオープンなプラットフォームなので、多くの人が異なったやり方で Android を出荷でき、したがって一部のパートナーがデバイスを出荷するとき Android の古いバージョンを搭載するからだ。その場合は確かに安全上の脆弱性が生じる。だからといって Android が安全でないことを意味するものではない。

Android was built to be very, very secure. The thing that you’re seeing is because Android is an open platform, many people can ship Android in many different ways and so there are some partners when they ship devices, they have an older version of Android. And sure you can have a security vulnerability there, but that doesn’t mean Android isn’t secure.

     *     *     *


マルウェアの 90% が Android を攻撃目標としているなどという数字を挙げられると、残念ながらかかるマルウェア会社を経営している頭のいい企業人ならそうすべきかもといわざるを得ない。しかしこういう見方は間違っている。多くのマルウェアが Android を攻撃するのはそれが他のいかなるスマートフォンプラットフォームより多く使われているからという考え方があることは明らかだ。

When you say numbers like 90% of malware is targeting Android, you know, I hate to point out that if you’re a smart business person running this malware company, that’s what you should do. It’s the wrong way to look at the lens. Obviously, you will always see more malware targeting Android because Android is used more than any smartphone platform by a pretty substantial difference.

     *     *     *

Sundar Pichai の発言内容がなかなか微妙な言い回しであることが分かる。グーグルがトランスクリプトを提供したのもそのためだろう。

[安全です:goto fail テストサイト

大騒ぎされた “goto fail” SSL/TLS バグが、OS X のアップデートでさっそく修正された。

Ars Technica: “Apple releases OS X 10.9.2, patches SSL flaw and adds FaceTime Audio support” by Andrew Cunningham: 26 February 2014

     *     *     *

OS X でも goto fail バグを修正

数か月のテストを経て、OS X 10.9.2 が一般公開された。通常のアップデートやセキュリティ項目に加えて、Mavericks でも “goto fail” SSL/TLS バグが修正されたことが大きな点だ。iOS 7 では金曜日に修正済みのものだ。SSL バグについては Software Update のリリースノートでははっきりとは触れられていないが、OS X 10.9.2 の セキュリティページでは触れられている。アップデートした後 Safari でいくつかの goto fail テストサイトを訪れてみて、このバグが修正されていることが確認できた。Mountain Lion および Lion のセキュリティアップデートもリリースされている。もっとも OS X の古いバージョンは goto fail バグの影響を受けない。今回のパッチはそれ以外の問題に対応するものだ。いずれにしてもユーザーは goto fail バグの心配をする必要がなくなった。

After several months of testing, Apple has released OS X version 10.9.2 to the general public. In addition to the typical laundry list of updates and security fixes, the second major update to Mavericks fixes the “goto fail” SSL/TLS bug that Apple patched in iOS 7 on Friday. The SSL bug isn’t mentioned in the release notes that appear in Software Update, but the bug is mentioned on Apple’s security page for 10.9.2. We were also able to confirm the fix by visiting several goto fail test sites in Safari after applying the update. Security updates for Mountain Lion and Lion have been provided as well, but previous versions of OS X were never affected by the goto fail bug in the first place—those patches will fix other problems, but users won’t need to worry about the goto fail bug either way.
