Microsoft’s new operating system, Windows Vista, is expected to be widely adopted and will likely have a significant effect on the security landscape. Symantec has continued to research potential issues and risks associated with the new operating system. LEARN MORE

New phishing economies

As phishing becomes entrenched as a mainstream attack activity, antiphishing techniques are improving and phishers are being forced to focus on new targets and adopt new methods. Symantec believes that, in the near future, phishers will expand the scope of their targets to include new industry sectors. LEARN MORE

SMiShing — Spam and phishing go mobile

In July 2006, Symantec reported that SMS and MMS had emerged as new vectors for spam and phishing activity. Subsequently, the term SMiShing was coined by the industry to describe this class of threat. Symantec speculates that SMS- and MMS-based phishing and spam will continue to increase. LEARN MORE

Flaw found in Citrix server client

Monday, March 5th, 2007

A flaw has been found in Citrix’s Presentation Server Client, an application that allows remote users to access corporate servers from outside the office.

Versions older than 10.0 could be vulnerable to a buffer overflow which would enable an attacker to compromise a user’s machine, according to researcher Karl Lynn of Juniper Networks, who discovered the flaw. Security advisory organization Secunia has rated the vulnerability as highly critical.

The vulnerability is caused by an error in the support for ICA (Independent Computing Architecture) connections through a proxy server. This may be exploited to execute arbitrary code when a user visits a malicious Web site, Citrix warned in an advisory last week.

ICA, designed by Citrix, is a proprietary protocol for application server systems. The protocol gives specifications for passing data between servers and clients, regardless of platform.

The vulnerability currently has no patch. Citrix recommends users protect themselves by upgrading to version 10.0 of Citrix Presentation Server Client.

Tom Espiner of ZDNet UK reported from London.

Flaw Found In Office 2007

Tuesday, February 27th, 2007

Researchers have discovered a “highly critical” security flaw in newly released Office 2007, despite Microsoft’s efforts to deliver its most secure version yet of the productivity software.

The consumer version of Office 2007, which launched only four weeks ago, is designed to withstand higher scrutiny by malicious code writers, as Microsoft subjected the software to code auditors as part of its security development lifecycle.

But researchers at eEye Digital Security found a file format vulnerability in Microsoft Office Publisher 2007, which could be exploited to let an outsider run code on a compromised PC.

“We were surprised we could find a flaw so quickly (after Office 2007 launched) and one that was part of their core products,” said Ross Brown, eEye’s chief executive.

An attacker could create a malicious publisher file, he said. Once the recipient opens the file, he or she could find the system infected and susceptible to a remote attack.

Researchers at eEye used a standard process of code auditing in discovering the vulnerabilities, Brown added. He noted that Microsoft either did not do a “good job” with its code auditing, or it may not have had enough people working on such a task.

Microsoft, meanwhile, said it is investigating eEye’s report of a possible vulnerability in Publisher 2007 and will provide users with additional guidance if necessary.

Executives at the software giant have recently said they expect security challenges to keep emerging, as an increasing number of devices connect to the Internet.

No public exploits have been reported in circulation for Publisher 2007 and, given Office 2007’s recent release, the flaw may hold little attraction for attackers who may wish to concentrate on software that is in greater distribution, eEye said.

New Internet Explorer Zero-Day Attack

Thursday, September 21st, 2006

As of September 18, 2006, Symantec Security Response is advising users to take extra precautions if they use any version of Microsoft Internet Explorer as a result of a new zero-day attack against the application.The attack leverages a previously unknown vulnerability in Microsoft Internet Explorer. This vulnerability is due to the way Internet Explorer handles Vector Markup Language (VML).

Currently, the vulnerabilities are being hosted primarily on adult and pornographic websites and used to attack users visiting those sites to install spyware onto the victim’s machine. It is important to note that although the attacks appear primarily on adult sites at the moment, it is possible that they may spread to other more mainstream websites on the internet. The spyware may include a variety of security risks such as keyloggers that will monitor the keystrokes in an attempt to steal financial and confidential information.

There are no patches available from Microsoft for the vulnerability at this point.

Symantec Security Response has analyzed the threat and has provided protection for it via LiveUpdate and Intelligent Update. The current Trojan that leverages the zero-day vulnerability to attack is detected as Trojan.Vimalov. Symantec Security Response is also releasing intrusion protection (IPS) signatures to proactively protect customers against attempts to exploit the Internet Explorer vulnerability itself.

If you are a current Symantec Customer running Norton AntiVirus or Norton Internet Security and regularly run LiveUpdate™, you are protected from this threat and its varients.

If you are unaware of the security status of your PC, please take one of the following actions:

Run LiveUpdate™

virus Definitions are available via the LiveUpdate or the Security Response Website.

Computer viruses are deadly. They often spread without any apparent contact and can be a nuisance, or even worse, fatal to your computer. Individuals who create these viruses, estimated at 10-15 new ones a day, are the electronic version of terrorists.

Their goal is to inflict havoc and destruction on as many people as possible by disabling, stealing, damaging, or destroying computer and information resources. (more…)

Don’t Fall For The Latest Internet Identity Theft Scam

Q: I use PayPal to accept credit cards for my online collectibles business. I recently received an email that my PayPal account was going to expire in five days if I didn’t click a link in the email and give them my PayPal account information. Being naturally paranoid I decided not to give this information and I’m happy to say that my PayPal account did not expire. Was this a scam?

The Bad Guys Are Phishing For Your Personal Information

Tuesday, June 13th, 2006

By: Tim Knox

Do you know what “phishing” is? No, it doesn’t mean you grab a phishin’ pole and head to the nearest phishin’ hole to catch some phish.

Phishing has a much more sinister connotation. The official Webopedia definition of “phishing” is as follows: The act of sending an e-mail to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft. The e-mail directs the user to visit a Web site where they are asked to update personal information, such as passwords and credit card, social security, and bank account numbers, that the legitimate organization already has. The Web site, however, is bogus and set up only to steal the user’s information. (more…)
