Unauthorized Access Attempt
Multiple versions of Microsoft Windows are vulnerable to a buffer overflow, caused by improper bounds checking when handling Enhanced Metafile (EMF) image formats. By creating a specially-crafted EMF image file containing malicious script, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the victim, once the file is opened. An attacker could exploit this vulnerability by hosting the malicious file on a Web site or by sending it to a victim as an HTML email.
Note: This vulnerability is different than the vulnerability addressed in Microsoft Bulletin MS04-011.
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS04-032. See References.
For Windows Server 2003:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS05-018. See References.
Microsoft originally provided a patch for this vulnerability in MS04-032, but it was superceded by the patch released with MS05-018.

Unauthorized Access Attempt
The Microsoft Distributed Transaction Service Coordinator (MSDTC) could allow a remote attacker to execute arbitrary code on the system, caused by a buffer overflow in the MSDTC. On Windows 2000, a remote attacker could send a specially-crafted network message and execute arbitrary code on the system. On Windows XP SP1 and Windows Server 2003, a local attacker could run a program followed by a specially-crafted application to gain elevated privileges and execute arbitrary code on the system.
Note: On Windows XP SP1, the vulnerability can be exploited remotely if the MSDTC is started. On Windows Server 2003, if support for Network DTC Access has been enabled, the vulnerability can be exploited remotely.
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS05-051. See References.

Novell eDirectory is a software package that uses a Lightweight Directory Access Protocol (LDAP) directory service for integrating enterprise and eBusiness programs. Novell eDirectory version 8.7.3, when running on Microsoft Windows, is vulnerable to a buffer overflow caused by improper bounds checking in the iMonitor. A remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with SYSTEM level privileges or possibly cause dhost.ext to crash.

With Myspace popularity exploding it was only a matter of time. There have been reports of a phishing attack which targets Myspace customers by requesting login details via a login page. The site was originally reported on "Technocrats" blog here: (http://djtechnocrat.blogspot.com/2006/05/myspace-phishing-attacks-on-rise.html
). Although the site was down at the time we tested it, we have no reason to believe this was not live bait and expect more attacks in the future. Site screenshot from "Technocrats" blog:

Hacktivism...wide scale defacement on more than 20,000 sites. |
May 19 2006 9:10AM |
Zone-H, the popular defacement reporting website, reported that more than 20,000 websites have been compromised and defaced. The sites were hacked by someone with the handle "Iskorpitx" and displayed the Turkish flag along with other information. See screenshot below. Luckily there appears to be no malicious code on the sites, however this shows the potential of how vulnerable machines are being exploited and have the potential for spreading malicious code in a widespread manner.

There's been quite a lot of buzz about the new 0-day Word vulnerability.
新しい0日間の Word 弱点について非常に多くのブンブンいう音がありました。
While talking about details of the vulnerability, it's easy to forget what the vulnerability was actually used for.
弱点の詳細について話をしている間に、弱点が実際に何のために使われたか忘れることは容易です。
According to the information we have, a US-based company was targeted with emails that were sent to the company from the outside but were spoofed to look like internal emails.
我々が持っているインフォメーションによれば、合衆国ベースの会社が外部から会社に送られた、しかし内部電子メールのように見えるために偽装された電子メールで狙いを定められました。
The emails contained a Word DOC file as an attachment. DOCs are a nasty attack vector. Few years ago, when macro viruses were the number one problem, many companies were not allowing native DOC files through their email gateways. Now that has changed, and DOCs typically get through just fine. But Word has vulnerabilities and users typically don't install Word patches nearly as well Windows patches.
電子メールはアタッチメントとして Word ドクターファイルを含みました。 DOCs は不快な攻撃ベクトルです。 ほとんど年前に、マクロウイルスがナンバー1の問題であったとき、多くの会社が(彼・それ)らの電子メールゲートウェイを通ってネイティブのドクターファイルを許していなくはありませんでした。 今それは変化しました、そして DOCs は典型的にただ素晴らしくて成し遂げます。 けれども Word は弱点を持っています、そしてユーザーが典型的にほとんど元気な Windows のパッチとして Word のパッチをインストールしません。
When run, the exploit file ran a backdoor, hid it with a rootkit and allowed unrestricted access to the machine for the attackers, operating from a host registered under the Chinese 3322.org domain.
走らせられるとき、 exploit ファイルはバックドアを走らせて、 rootkit でそれを隠して、そして、中国語の 3322.org ドメインの下で登録されたホストから稼働して、攻撃者にマシンへの無制限のアクセスを割り当てました。
3322.org is a free host bouncing service in China. Anybody can register any host name under 3322.org (like whatever.3322.org) and the service will point that hostname to any IP address you want. There's actually a series of such services, including 8866.org, 2288.org, 6600.org, 8800.org and 9966.org. There are tons of useful things you can do with such host-resolving service. And tons of bad things too.
3322.org は中国でサービスを跳ね上げる無料のホストです。 誰でも(whatever.3322.org のような) 3322.org の下でどんなホスト名でも登録することができます、そしてサービスはあなたが欲するどんな IP アドレスにでもそのホスト名を向けるでしょう。 8866.org 、 2288.org 、 6600.org 、 8800.org と 9966.org を含めて、実際にこのようなサービスのシリーズがあります。 あなたがこのようなホストを変換するサービスですることができる有用なことのトンがあります。 そして同じく良くないことのトン。
Now, we've seen these kinds of attack before.
今、我々は前にこれらの種類の攻撃を見ました。
In March 2005, somebody was sending out dozens of emails to US government email addresses, spoofed to be from Washington Post. The email content talked about "international IPR conventions China has acceded to". The attached DOC file dropped a backdoor that connected to a host under 8866.org.
2005年3月に、誰かが、「ワシントン・ポスト」からであるためにペテンにかけられて、合衆国政府の電子メールアドレスに多数の電子メールを送っていました。 電子メール内容は「中国が応じた国際 IPR 会議」について話をしました。 付加されたドクターファイルは 8866.org の下でホストに接続したバックドアを落としました。
In September 2005, somebody sent several batches of EU-themed emails to addresses at the EU Parliament. Email topics included "Parliamentary Assembly", "Assembly of Council of Europe" and "Parliamentary Assembly Declaration". Emails contained a DOC that connected to a host under 3322.org.
2005年9月に、誰かがEU議会でアドレスに数回分のEUをテーマにした電子メールを送りました。 電子メールトピックが「議会の議会」、「ヨーロッパ会議の議会」と「議会の議会公表」を含みました。 電子メールが 3322.org の下でホストに接続したドクターを含みました。
In March 2006, a big European company received emails that were spoofed to look like internal job applications. The attached DOC file dropped a backdoor that connected to a host under 3322.org.
2006年3月に、大きいヨーロッパの会社が内部の求職申し込みのように見えるために偽装された電子メールを受け取りました。 付加されたドクターファイルは 3322.org の下でホストに接続したバックドアを落としました。
In April 2006, another European company was targeted by a similar attack, this time connecting to a host under 8866.org.
2006年4月に、もう1つのヨーロッパの会社が、今回は 8866.org 以下のホストに接続して、類似の攻撃によって目標を定められました。
And now in May 2006, this latest case complete with a zero-day exploit, connecting to a host under 3322.org.
そして2006年5月、 3322.org の下でホストに接続しているゼロ日 exploit を完備したこの最近の事例で今。
So, should you block access to hosts under 3322.org, 8866.org and others? Depends. It's kind of like blocking access to Geocities: you'd block lots of bad stuff - and lots of good stuff. But then again, most users of these services are in China. If you're not in China and your users are not supposed to access different Chinese services, blocking might not break too many things.
それで、あなたは 3322.org 、 8866.org と他のものの下でホストへのアクセスを阻止するべきですか? 事情によります。 それはまあ Geocities へのアクセスを阻止するようです:あなたはたくさんの良くない物 - そしてたくさんの良い物をブロックするでしょう。 けれどもそれから再び、これらのサービスのたいていのユーザーが中国にいます。 もしあなたが中国にいなく、そしてあなたのユーザーが異なった中国のサービスにアクセスするはずではないなら、ブロックすることはあまりに多くのことを破らないかもしれません。
We'd recommend you'd at least check your company's gateway logs to see what kind of traffic you have to such services.
我々はあなたがあなたがこのようなサービスにどんな種類のトラフィックを持っているか見るために少なくともあなたの会社のゲートウェイが木材を伐採することを調べるであろうことを勧めるでしょう。
