NEWS!!! CRITICO - Vulnerabilidad 0-day en Java 7

Vulnerabilidad 0-day en Java 7

Fecha de Publicación: 2012-08-27 11:30:00

Sistemas Afectados
La vulnerabilidad explotada hasta el momento afecta a Java 7 (1.7) Update 0-6. No afecta a la versión 6 de Java ni versiones inferiores. Funciona en todas las versiones de Internet Explorer, Firefox y Opera excepto en Chrome.

Descripción
Se ha descubierto una vulnerabilidad 0-day que afecta a Java 7 (1.7) Update 0-6.

Severidad:
GRAVE

Solución
Por el momento no existe ningún parche oficial. Se recomienda desactivar Java en el navegador hasta que se solucione la vulnerabilidad.
Michael 'mihi' Schierl (schierlm at gmx.de) propone una solución temporal (no oficial) con la que mitigar el exlpoit actual en instalaciones con Java 7. Dicha solución consiste en crear un sub-directorio dentro de lib (dentro del directorio de instalación de Java 7), nombrarlo como endorsed, copiar el parche temporal en dicho directorio y reiniciar el navegador. Para más información sobre esta solución así como para solicitar dicho parche consulte DeependResearch. No obstante se recomienda deshabilitar java hasta que exista un parche oficial.

Detalle
Aunque el número de ataques reportados hasta el momento ha sido relativamente bajo (en FirEye se describe el exploit utilizado en algunos ataques dirigidos), es probable que su número aumente debido a la naturaleza de la vulnerabilidad.
Actualización: según informan en Rapid7, habrá un exploit funcional para Metasploit en un par de horas.

News!!! NEW Exchange version :Exchange 2013

Increase productivity

• Give your users an intuitive, touch-enabled inbox experience. Your users can get more done from anywhere with a clean, uncluttered inbox that focuses on the relevant and important information.
• Allow your users to work better together on teams and projects. Site mailboxes enable your users to collaborate on projects, get up to speed quickly on teams they join, and share information easily. Co-authoring, document storage, and versioning is provided by SharePoint, while messaging is handled by Exchange with a complete user experience, including document access, within Outlook.
• Customize Exchange by integrating web-based apps for Outlook and Outlook Web App. Help your users spend less time switching between apps and make their communications experience more powerful with an extension model that allows you to provide easy plug-in access to web-based apps within both Outlook and Outlook Web App. With single sign-on to multiple apps, you can reduce complexity for users and give them secure, authorized access for each approved application.

Keep your organization safe

• Eliminate email threats before they reach your network. Exchange actively protects your communications with built-in defenses against viruses, spam, and phishing attacks.
• Protect your sensitive data and inform users of internal compliance policies. Prevent users from mistakenly sending sensitive information to unauthorized people. Data Loss Prevention (DLP) features identify, monitor, and protect sensitive data through deep content analysis, and PolicyTips in Outlook inform users about policy violations before sensitive data is sent. Built-in DLP policies are based on regulatory standards such as PII and PCI, plus Exchange can support other policies important to your business.
• Enable your compliance officers to run In-Place eDiscovery across Exchange, SharePoint, and Lync from a single interface. Ensure internal and regulatory compliance by using the new eDiscovery Center to identify, hold, and analyze your organization's data from Exchange, SharePoint, and Lync. The data always remains in place, so you never have to manage a separate store of data.

NEWS!! 'Flamer' virus could be most sophisticated malware, warns Kaspersky

Be aware!!
28/05/2012
A new virus referred to as 'Flamer' could be one of the most sophisticated pieces of malware yet, Kaspersky has warned.

According to the internet security giant, the Win32.Flamer "attack toolkit" that is currently targeting Iran and other countries in the Middle East offers much more of at threat than most malware attacks.

This is partially due to the complexity of the program, meaning that it is capable of undertaking a wide number of potentially damaging actions.

Como renombrar una cuenta con powershell

Buenas tardes amig@s,
después de hacer un script para crear cuentas de usuarios, casilla y usuario de lync, me dí cuenta que el nombre de la cuenta estaba mal, debería tener el display name en lugar del samAccountname
Acá el script

$user=import-csv .\saMacc.csv
ForEach ($u in $user)
{
$prop=get-aduser -Identity $u.user -property *|select-object distinguishedName,displayname
foreach ($p in $prop) {

Rename-ADObject -identity $p.distinguishedName -NewName $p.displayname
if($error.count -gt 0){
$error[0].ToString()
Write-host "Rename failed :"   $u.user
$error.clear()
}
else
{
Write-host "Rename success :"   $u.user
}
}

Exchange 2010 SP2 está entre nosotros

Amigos,
esta semana lo probaré en mi lab y les contaré los resultados

http://www.microsoft.com/download/en/details.aspx?id=28190

The Exchange Team is pleased to announce that in the second half of calendar year 2011 we will be releasing Exchange Server 2010 Service Pack 2 (SP2) to our customers. With SP2, the following new features and capabilities will be included:

• Outlook Web App (OWA) Mini A browse-only version of OWA designed for low bandwidth and resolution devices. Based on the existing Exchange 2010 SP1 OWA infrastructure, this feature provides a simple text based interface to navigate the user’s mailbox and access to the global address list from a plurality of mobile devices.
• Cross-Site Silent Redirection for Outlook Web App With Service Pack 2, you will have the ability to enable silent redirection when CAS must redirect an OWA request to CAS infrastructure located in another Active Directory site.  Silent redirection can also provide a single sign-on experience when Forms-Based Authentication is used.
• Hybrid Configuration Wizard Organizations can choose to deploy a hybrid scenario where some mailboxes are on-premises and some are in Exchange Online with Microsoft Office 365. Hybrid deployments may be needed for migrations taking place over weeks, months or indefinite timeframes. This wizard helps simplify the configuration of Exchange sharing features, like: calendar and free/busy sharing, secure mailflow, mailbox moves, as well as online archive.
• Address Book Policies Allows organizations to segment their address books into smaller scoped subsets of users providing a more refined user experience than the previous manual configuration approach. We also blogged about this new feature recently in GAL Segmentation, Exchange Server 2010 and Address Book Policies.
• Customer Requested Fixes All fixes contained within update rollups released prior to Service Pack 2 will also be contained within SP2. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.

In order to support these newly added features, there will be a requirement for customers to update their Active Directory schema. We’ve heard the feedback loud and clear from our customers on multiple occasions regarding delays that can be caused to deployment as a result of needing to update your schema and as such with the release of Exchange 2010 SP2 are communicating the required changes ahead of release in order to assist our customers with planning their upgrade path ahead of time.
We hope these announcements come as welcome news to you. It is our custom to provide ongoing improvements to features, functionality and security of Exchange Server, based largely on customer feedback, and to provide continual innovation on an already great messaging product. We look forward to receiving your comments and announcing more detailed information as we continue to develop the features that will be included in SP2.

UPDATED!! ¿Por qué no podemos abrir más de dos calendarios compartidos con Outlook 2003 y Exchange 2010? ¿Cómo lo resuelvo? "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action."

UPDATED!!!

Buen día amig@s,
después de mover una casilla desde Exchange 2003 a Exchange 2010, manteniendo nuestro Outlook 2003 como cliente, y haber trabajado con varios calendarios compartidos, al querer abrír el segundo calendadio compartido obtenemos el siguiente error:

"The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action."

NEWS!!! Announcing the re-release of Exchange 2010 SP1 Rollup 4

Este parece que funciona :)
Del site del Team de Exchange

"Earlier today the Exchange CXP team released an updated version of Update Rollup 4 for Exchange Server 2010 SP1 to the Download Center. This updated release is being made available after a complete review and revalidation of the list of fixes included in the previously released version of Rollup 4 dated June 22, 2011.
The review completed by the Exchange CXP team determined that the issue identified in 'KB 2581545: The copy or move operation on a folder that contains subfolders does not work as expected after you install Update Rollup 4 for Exchange Server 2010 SP1 dated June 22, 2011’ introduced a serious regression in the original release of Rollup 4. As a result, a new version of Rollup 4 dated July 23, 2011 has been tested and released with the change that caused the regression removed. The re-release of Rollup 4 is tracked by 'KB 2579150: Description of Update Rollup 4 for Exchange Server 2010 Service Pack 1'.
The updated Rollup 4 is being released to allow customers to install the list of fixes previously committed to on the normal rollup schedule using normal rollup installation routines without the need for further action. The re-released version of Rollup 4 is functionally equivalent to the combination of the original Rollup 4 release and (the interim updatein) KB 2581545. Here are answers to some install questions:

• Customers who have installed KB 2509910 (Rollup 4, dated June 22, 2011) and KB2581545 (fix for Rollup 4 regression) do not need to install KB 2579150 (re-released Rollup 4) but may do so if they choose to.
• Customers who have already installed KB 2581545 and want to update their systems to the updated Rollup 4 should first uninstall KB 2581545 (or any interim updates) prior to installing the new rollup.
• You do not need to uninstall original RU4 (KB 2509910) to install the re-released RU4 package (KB2579150).
• The re-release of Rollup 4 does not change the release plans for Update Rollup 5 for Exchange Server 2010 Service Pack 1. Rollup 5 is currently scheduled to release in August 2011.

NEWS !!! AGAIN!!!! Exchange 2010 SP1 RU4 Removed from Download Center

We have discovered an issue impacting some customers who have installed Exchange 2010 SP1 RU4 into their Exchange environment and as a result have removed SP1 RU4 from Download Center and recommend customers do not proceed with any planned deployments of SP1 RU4.

A small number of customers have reported when the Outlook client is used to move or copy a folder that subfolders and content for the moved folder are deleted. After investigation we have determined that the folder and item contents do not appear in the destination folder as expected but may be recovered from the Recoverable Items folder (what was previously known as Dumpster in older versions of Exchange) from the original folder. This behavior occurs due to a customer requested change in SP1 RU4 which allowed deleted Public Folders to be recovered. Outlook and Exchange are not correctly processing the folder move and copy operations causing the folder contents to appear to be deleted. OWA and Exchange Web Services clients are not affected by this change and process the folder move or copy actions correctly.
