Why Corporate Networks Are Vulnerable To Virus / Spyware

July 14th, 2011

The biggest mistake is to ignore network share access rights – responsible for 35% of incidents. In such a case there might be open sharing with access rights configured as “full access” to everyone on an internal file server or end-user work desktop, e.g., a shared public document workspace where all documents are stored. Sooner or later this can become a prominent source of malware redistribution throughout the organization.

Modern malware takes advantage of existing vulnerabilities. A network with just a single missing patch can be put at serious risk. And this is a common issue seen mostly in small to medium organizations with end-users numbering less than 100. These organizations either do not have enough expertise or ignore patching completely. This mistake is responsible for 25% of incidents.

Use of multiple vendor antimalware solutions (15% of incidents) may lead to a situation where it is hard to mitigate malware attacks. This may occur if one of the vendors does not respond fast enough to attacks. Delays in responses may run to days, weeks or even months. During this time the solution of another vendor would detect and remove malware, but only in its part of the network – and malware would attack it from the unprotected side.

A partially protected environment (15% of incidents) is where an antimalware solution is installed on part of the network, leaving other resources unprotected.

Firmware vulnerability (5% of incidents) may be exploited by attackers through hardware devices, such as routers, firewalls and other network appliances.

And another relatively infrequent mistake (also 5% of incidents) is to believe that software downloaded from the Web is always perfectly sound software.

It’s important that your IT vendor understands these risks and implements solutions to minimize them.  Call us today and we will evaluate your current network setup to minimize your risk of being attacked.

Exchange Server and the new Iphone OS

June 30th, 2010

Apple recently released the iPhone4. It uses a new iPhone operating system – iOS4 – that is also available for download on older iPhone devices. The new iPhone operating system is adversely impacting  Exchange Server customers as well as customers of other email providers.

The following notification summarizes these issues and the critical actions we ask that your iPhone4 and iOS4 users immediately take in response.

The actions are in support of our commitment to providing the highest service quality for all RescueTech customers. We will continue to post updates as the situation evolves and Apple provides further details.

Summary of Issues
Exchange users who use an iPhone4 or upgraded an older iPhone to iOS4 are experiencing difficulties syncing their contacts, mail, and calendar via ActiveSync. Additionally, iOS4 is creating significant artificial load on Exchange servers, resulting in performance slowdowns for users on other devices and mail clients.

An Internet search for “iOS4 Exchange” will provide further information related to these issues, which are affecting all email providers that use the ActiveSync protocol with iPhones.

Steps Your Organization Must Take
iPhone users who use the iPhone4 or upgraded to iOS4 must install a related Apple configuration patch on their iPhone. The patch, along with installation directions, can be found here:
http://support.apple.com/kb/TS3398.

Failure to install this patch will result in incomplete sync of user items and may cause performance issues.

Further Technical Details on the Issue and Our Response
The iOS4 issues are driving random application pool instability on Exchange 2007 CAS servers. Microsoft confirmed this instability is caused by iOS4 and classified this as a client side issue related to the Apple iOS4 update. Microsoft is not planning to release a patch or update. The instability will manifest itself as connection failures or slow performance when using Outlook and other clients. Outlook Web App (OWA) is not impacted and continues to function normally. If you are having connectivity issues we recommend using OWA to retrieve your mail.

Get Office 2010 for free!

April 4th, 2010

With Office 2010, one of the biggest changes is how many ways there are to get Microsoft’s most profitable software program for free.

In addition to the free, browser-based Office Web Apps, Microsoft is also offering PC makers the ability to install a basic version of Office on new computers. The new program, Office Starter, includes a stripped-down version of Word and Excel. PC makers, retailers and Microsoft can all make money if the PC buyer later upgrades to a paid version of Office.

Combine that with RescueTech Hosted Exchange 2010 which includes Outlook 2007 and you will be all set.

The Internet can make you smarter.

February 22nd, 2010

Though it may not always feel like it, the Internet is actually making us smarter, at least according to a new survey of scientists, business leaders, and technology developers.

A collection of 900 experts interviewed for the Pew Internet report The Future of the Internet IV, released last Friday, were asked their views on how the Internet is affecting us–now and in another 10 years. Though most felt that the Internet can and would improve our reading, writing, and overall grasp of knowledge, some were reluctant to jump on that bandwagon.

“Three out of four experts said our use of the Internet enhances and augments human intelligence, and two-thirds said use of the Internet has improved reading, writing, and rendering of knowledge,” said Janna Anderson, study co-author and director of the Imagining the Internet Center, in a statement. “There are still many people, however, who are critics of the impact of Google, Wikipedia, and other online tools.”

BlackBerry not receiving email?

December 23rd, 2009

Research in Motion on Tuesday night confirmed a BlackBerry outage affecting some users in North and South America – the company’s second in several days.
The problems do not appear to affect calling or text messaging, but users are not receiving e-mails. Others have reported problems with BlackBerry Messenger (BBM), an instant message program available on the devices.
“Some BlackBerry customers in the Americas are experiencing delays in message delivery,” RIM said in a statement. “Technical teams are actively working to resolve the issue for those impacted. RIM apologizes for any inconvenience experienced by customers.”
The outage is the second for RIM in that past five days. For several hours on Thursday, users were once again not able to receive or send e-mail messages.

Microsoft Bug Fixed

December 15th, 2009

Microsoft says it has a fix for a bug that was keeping Office 2003 users from being able to access some rights-managed files.
The bug, which cropped up on Friday, meant that users of Office 2003 were unable to access files protected using Microsoft’s rights management service (RMS) technology.

Microsoft posted a software download known as a “hotfix” on Saturday that it says resolves the issue.
“The issue of the inability to open Office 2003 documents protected with RMS has now been resolved with a hotfix,” Microsoft said in a short statement on its Office sustained engineering blog.

Upgrading XP to Windows 7

October 29th, 2009
Because you can’t upgrade over XP, there are some steps you’ll want to take before you install Windows 7 to make the process easier. This game plan also works if you plan to do a clean or custom install on a Windows Vista system.
* Make an inventory of the software you’ll want to reinstall on Windows 7. This may be a good time to do some housecleaning. Identify the programs you really need and plan to keep them, and cast off those you don’t.
* Download, install and run the Windows 7 Upgrade Advisor at www.microsoft.com/windows/windows-7/get/upgrade-advisor.aspx. This will scan your PC and point out compatibility issues with hardware and software. You may have software that won’t run on Windows 7, and you’ll need to upgrade to a newer version of that program, or obtain a patch if available.
* Download and save to a CD, DVD or external drive any software patches you’ll need. Do the same for any Windows 7 drivers that are available for your key hardware, video and audio adapters, printers, mice, keyboards, scanners, etc.
* Research and identify the security software you’ll want to install. Don’t expect the antivirus or antispyware programs you bought two years ago to work on Windows 7. Microsoft has a Web page that lists developers with compatible security titles at www.microsoft.com/windows/antivirus-partners/windows-7.aspx.
* Make a backup of your documents, music, videos and photos, to an external drive. Check the help files for your e-mail program to see how to export your mail folders, then save those to the external drive as well. If you’re really cautious, make a disk image of your entire system using software such as Acronis TrueImage, Norton Ghost or Norton Save & Restore so you can recover your Windows XP setup in case something goes horribly wrong.
* Check the system requirements for Windows 7 to see if your PC is powerful enough. Although Microsoft says 1 GB of RAM will work with the 32-bit version, I’d recommend you have at least double that. Install your RAM or any hardware upgrades before you install Windows 7.
* Once you have Windows 7, you can start the installer from within XP. It will do additional compatibility checks, then reboot the system to begin the installation. I’d recommend doing the Custom install, because it does provide a secondary copy of your data files.
* When the installation is complete, install the latest Windows 7 drivers, then the antivirus software you’ve selected and let it update its malware definitions.
* Manually run Windows Update to check for any patches and fixes.
* Before you install any of your software, live with this installation for a while. Play around with Windows 7, learning its differences before you have to rely on it for real work. Give it a few days before installing your software, and copying data back to the hard drive.
Once your installation is the way you like it, consider using the Backup and Restore function in Windows 7 to make an image of your existing hard drive. You can use this later if you need to start over from scratch – and it will come in handy when Windows 8 rolls around in a few years!

Virus Removal

October 29th, 2009

A vulnerability in Microsoft GDI+ may allow remote code execution. The vulnerability exists in the way GDI+ allocates buffer size when handling WMF image files. The vulnerability could allow remote code execution if a user opens a specially crafted WMF image file or browses to a Web site that contains specially crafted content. Successful exploitation of this vulnerability could allow an attacker to take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. RescueTech can make sure you have the appropriate patches and updates to protect your system.
