Hacker Serang 13 Situs NASA



Apakah 13 memang angka sial sehingga seorang hacker asal Brazil beridentitas drwxr hanya menyerang tiga belas situs yang dimiliki NASA?

Pengumuman yang dilansir Zone-H—sebuah organisasi yang memantau aktivitas hacking—menyebutkan bahwa hacker telah memodifikasi halaman indeks di situs-situs NASA untuk menyatakan opininya perihal perang. Sebuah pesan ditinggalkan sang hacker: The war in Iraq, kill is a play (perang di Irak, membunuh jadi permainan). Pesan ini sekaligus memuat link ke rekaman video CNN yang memperlihatkan aksi serdadu AS di Irak.

Situs utama NASA, www.nasa.gov diduga lolos dari serangan karena masih tetap online hingga pagi ini.

Zone-H, mengutip Netcraft Ltd., sebuah konsultan Internet asal Inggris, mengatakan bahwa situs-situs milik badan ruang angkasa AS tersebut menggunakan Web server Apache 1.3.27 dengan PHP (bahasa script open source yang biasa digunakan untuk membuat dynamic Web pages) dan beberapa modul Apache pada sistem Linux.

Sampai kemarin, para pejabat NASA belum dapat dimintai keterangan. Namun agaknya NASA sudah menonaktifkan situs-situsnya, karena sudah tidak bisa diakses.

Situs-situs NASA yang diserang antara lain : situs Computing, Information and Communications Technology Program (www.cict.nasa.gov); Advanced Supercomputing Division/ Numerical Aerospace Simulation Systems Division (www.nas.nasa.gov); Information Power Grid (www.ipg.nasa.gov); dan NASA Research & Education Network (www.nren.nasa.gov).

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Usbd

The Trojan opens a random listening port and periodically attempts to connect to a remote website to register itself.

The Trojan also has the ability to download and execute a file from a remote
website.

Troj/Cidra-D appears to have been spammed out. The email has the following characteristics:

The subject line is "This your photo?", possibly interspersed with non-Roman characters. For example:

+This your photo?
This+ your photo?
This your photo?
This y_our photo?
This your pho+to^?

Informatics dan UI Hadirkan Sertifikasi Hacker



infokomputer.com, Makin meningkatnya resiko keamanan yang ditimbulkan para hacker, baik di dalam maupun di luar perusahaan membuat banyak perusahaan semakin menyadari perlu adanya seseorang yang memahami pola pikir dan cara kerja hacker. Untuk itu biasanya mereka menyewa perusahaan layanan
ethical hacker, atau memiliki seorang yang memiliki sertifikat ethical hacker di dalam perusahaan tersebut.

Mengantisipasi permintaan tersebut, bekerjasama dengan GDLN Universitas Indonesia, Informatics memperkenalkan sertifikasi hacker bertaraf internasional. Pelatihan bagi mereka yang ingin mendapatkan sertifikasi Certified Ethical Hacker (CEH) ini dihadirkan dengan lisensi dari EC
Council yang berpusat di New York.

Seorang yang mendapatkan sertifikasi CEH adalah profesional yang memiliki kemampuan untuk mengerti dan mengetahui cara melihat kelemahan sebuah sistem.

Untuk terus mengikuti perkembangan, materi pelatihan untuk mendapatkan CEH diperbarui setiap dua bulan, kata Sanjay Bavisi, Managing Director EC Council Asia Pacific. Pelatihan ini berlangsung selama 40 jam.

Dalam pelatihan tersebut, peserta diajarkan pola berpikir seorang hacker. Dengan demikian, peserta dapat melindungi sistem sekuriti dengan lebih baik.

Materi yang dibahas pada pelatihan mencakup sejumlah teknik yang umum digunakan hacker,seperti Trojan dan backdoor, sniffing, Denial of Service, Session Hijacking, Social Engineering, teknik mengcrack password, Virus dan worm, IDS, Firewall, Honeypot,
hacking ke sistem Windows, Linux, dan Novell, Firewall, dan sebagainya termasuk kriptografi.

Untuk pelatihan selama lima hari kerja, Informatics bekerja sama dengan GDLN UI menawarkan biaya pelatihan sebesar delapan juta rupiah.

Detection
A virus identity (IDE) file which provides protection is available now from the Latest virus identities section, and will be incorporated into the May 2004 (3.81) release of Sophos Anti-Virus.


Enterprise Manager and PureMessage customers will be automatically protected at their next scheduled update.

Sophos has received several reports of this virus from the wild.

Note: Sophos has been detecting W32/Bagle-R since 08:33 GMT on 18 March, and has issued this new IDE to improve detection.


Description
Please note: Sophos Anti-Virus also detects the W32/Bagle-S and W32/Bagle-T worms as W32/Bagle-R.
W32/Bagle-R is a mass-mailing virus that spreads in an unusual manner.

W32/Bagle-R spreads via a "carrier" email which does not contain the worm as an attachment.

The email has the following charactersitics:

The Sender address is spoofed.

Subject line: randomly chosen from -

Re: Hi
Encrypted document

There is no visible message text.

The email addresses are harvested from the hard drive of infected machines by searching for files with the extensions WAB, TXT, MSG, HTM, SHTM, STM, XML, DBX, MBX, MDX, EML, NCH, MMF, ODS, CFG, ASP, PHP, WSH, ADB, TBB, SHT, XLS and OFT.

W32/Bagle-R avoids email addresses containing the following:

@hotmail, @msn, @microsoft, rating@, f-secur, anyone@, bugs@, contract@, feste, gold-certs@, help@, info@, nobody@, noone@, kasp, admin, icrosoft, support, ntivi, unix, linux, listserv, certific, sopho, @foo, @iana, free-av, @messagelab, winzip, google, winrar, samples, abuse, panda, cafee, spam, @avp., noreply, local, root@, postmaster@

When you open the "carrier" email, the email attempts to exploit a vulnerability in Outlook. The exploit may cause the email client to automatically download W32/Bagle-R from the IP address of a computer infected with a Bagle variant. The IP address of the computer "server" serving the Bagle executable is randomly chosen from the list of of 590 IP addresses from the virus data section.

The security vulnerability was reportedly patched by Microsoft in Microsoft Security Bulletin MS03-040.

The "carrier" email connects to port 81 of the host and opens an HTML file. The HTML file drops and launches a Visual Basic script q.vbs. This script connects to the same server and downloads W32/Bagle-R via an HTTP (web) request to TCP port 81.

The downloaded copy of W32/Bagle-R is placed into your system folder with the name directs.exe or direct.exe (depending on the variant).

W32/Bagle-R loads on your PC and terminates a wide range of security applications. The list of applications is:

A registry entry is added to the following key so that the program directs.exe loads every time you logon to your computer:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

W32/Bagle-R makes multiple copies of itself into folders which are likely to be part of a file-sharing network. The filenames used are:
Microsoft Office 2003 Crack, Working!.exe
Microsoft Windows XP, WinXP Crack, working Keygen.exe
Microsoft Office XP working Crack, Keygen.exe
Porno, sex, oral, anal cool, awesome!!.exe
Porno Screensaver.scr

Porno pics arhive, xxx.exe
Windows Sourcecode update.doc.exe

Windown Longhorn Beta Leak.exe
Opera 8 New!.exe
XXX hardcore images.exe
WinAmp 6 New!.exe
WinAmp 5 Pro Keygen Crack Update.exe
Adobe Photoshop 9 full.exe
Matrix 3 Revolution English Subtitles.exe
ACDSee 9.exe

W32/Bagle-R infects programs on your PC by appending itself to existing EXE files. The danger of W32/Bagle-R can be mitigated not only by updating Sophos Anti-Virus but by blocking connections to TCP port 81 through your network firewall (this port is unlikely to be required for any real services).

Blocking outbound port 81 connections stops computers on your network from downloading the worm from outside. Blocking port 81 inbound means that even if you do get infected you will not pass the virus on to others.

You should also apply the latest Internet Explorer/Outlook Express patches from Microsoft. The vulnerability used by W32/Bagle-R is described in Microsoft Security Bulletin MS03-040 and is referred to as the "Object Tag vulnerability in Popup Window".
