Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

The next generation of security threats, Microsoft

noreply@blogger.com (Mandy) — Wed, 05 Dec 2007 17:48:00 +0000

REDMOND, Wash.--Microsoft security engineer Robert Hensing had a question for the hundreds of his company's developers seated before him: can a person's PC become infected with a rootkit simply by opening a PowerPoint file?

In the packed conference center, a smattering of developers raise their hands. Nearby, in an adjacent room, where hackers invited to speak at Microsoft's Blue Hat conference watch the presentations on TV, an entire table of hands go up.

"That's one thing I want you to take away from this," Hensing tells the Microsoft developers. "Applications are dangerous."
"We're attacking today's problems. We certainly have to do that. We also need to get ahead."
--Matt Thomlinson, head of security engineering efforts, Microsoft

Indeed, even though Microsoft has spent a fortune securing Windows, experts say that hackers are moving beyond the operating system. Threats such as rootkits, which can corrupt an operating system, can now be transferred by applications or Web-based programs. A new crop of Web-connected mobile devices represent another emerging threat.

"Operating system vulnerabilities are on the decline," Hensing said in his talk at the most recent Blue Hat security conference in September. "Application vulnerabilities are on the rise."

In part, Microsoft is something of a victim of its own success in securing Vista and Windows XP before it. Halvar Flake, a security researcher who attended the latest Blue Hat, estimates the total cost of Microsoft's years-long security push at more than $1 billion, with a significant chunk spent on Vista. George Stathakopoulos, a general manager in Microsoft's security unit, wouldn't say how much Microsoft has spent, but said that it's "a big number."

Flake, CEO of security firm Zynamics, said that all of that spending has paid off. "Vista is the most difficult mainstream OS to break into that I've ever seen," he said. Because it is harder to hack, it is more expensive for criminals to target.

Paradoxically, it's not clear that Vista's improved security is persuading people to move to the operating system any faster. "Security is a tough sell, really," Flake said. "Customers can't really measure it."

Vista's security is likely making life more difficult for hackers. Flake said the malicious side of him "would hope Vista is a huge flop" and, as a result, that no company ever spends that kind of money and effort securing an operating system.

The true measure of the effectiveness of Vista's new security likely won't be measured for years. Microsoft and other vendors often tout how their newest releases have many fewer flaws than previous versions. That's usually true, but it's only part of the picture. Most of the major operating system vendors have seen their total number of vulnerabilities rise since 2004. New operating systems tend to have fewer flaws upon release, but operating systems live for five to seven years.

As a result, operating system makers try to design products to withstand the types of attacks their software may face toward the middle and end of its life--when operating systems are most heavily adopted.

"We're attacking today's problems," said Matt Thomlinson who heads Microsoft's security engineering efforts. "We certainly have to do that. We also need to get ahead."

The attacks themselves, meanwhile, have grown increasingly targeted. From the mass mailers, to broad phishing scams, to more recent attacks aimed at individuals. Experts expect that trend to continue, with malicious software growing ever more evasive.

Malicious software getting more complex
This year marks a turning point, according a report this week from Cisco Systems-owned IronPort Systems. "For a time, security controls designed to manage malware were working," said Tom Gillis, vice president of marketing for IronPort. "Just when malware design seemed to have reached a plateau, new attack techniques have burst forth, some so complex--and obviously not the work of amateurs--they could have only been designed by means of sophisticated research and development."
Photos: Microsoft's bug hunters

Modern malicious software, IronPort suggests, borrows many characteristics from today's social-networking sites. They are collaborative and adaptive. Plus, the company said, they fly under the radar, "living on enterprise or residential PCs for months or years without detection."

IronPort sees Trojan horses and malicious software becoming "increasingly targeted and short-lived," which will make them still harder to spot.

Layered atop that trend is the rise of new attacks that target software applications. While there are only a handful of major operating systems, there are literally thousands of applications, some used by millions of people.

Microsoft has spent significant time and money on securing its applications. After the experience of Slammer, for example, the company's SQL Server database became a model within the company for how to adopt secure development. Security researcher Dan Kaminsky, who has also attended Blue Hat and done a significant amount of security consulting for Microsoft, said that SQL Server has made significant gains over Oracle thanks to those improved practices.

The Office team, too, has taken note of the fact that its documents are frequently targeted as means for an attack. One of the less-discussed reasons for Office's new XML file formats, in fact, is that they are designed from scratch to be more secure, according to Microsoft.

Technical details

This Trojan has a malicious payload. It is a Windows PE EXE file. It is 11776 bytes in size. It is packed using UPX. The unpacked file is approximately 48KB in size. It is written in Delphi.
Payload

Once launched, the Trojan will:

1. modify the following system registry key values:
[HKCU\Software\Microsoft\Internet Explorer\Main]
"Start Page" = "http://www.find-online.net/index.htm"
[HKCU\Software\Microsoft\Internet Explorer\Main]
"Use Search Asst" = "yes"
[HKCU\Software\Microsoft\Internet Explorer\Main]
"Search Page" = "http://www.find-online.net/index.htm"
[HKCU\Software\Microsoft\Internet Explorer\Main]
"Search Bar" = "http://www.find-online.net/sp.htm"
[HKCU\Software\Microsoft\Internet Explorer\SearchURL]
"Default" = "http://www.find-online.net/index.htm"
[HKCU\Software\Microsoft\Internet Explorer\SearchURL]
"provider" = "gog1"
[HKLM\Software\Microsoft\Internet Explorer\Search]
"SearchAssistant" = "http://www.find-online.net/sp.htm"

These changes modify the configuration of Internet Explorer.
2. create the following registry key:
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"ziphelp" = "%WinDir%\ziphelp.exe"

Date Added: 9/22/2004
Origin: N/A
Length: Varies
Type: Virus
SubType: Generic Worm
DAT Required: 4394

Virus Characteristics
Due to the large volume of members of this virus family, the size of extra.dats required to detect these is very large. AVERT have therefore split the detection into multiple drivers although the behavior of all members is broadly similar.

Please review the W32/Sdbot.worm.gen description.

The W32/Sdbot.worm.gen.z exhibits the following behavior:

* The worm file is eXPressor protected
* Mlqm.exe process will listen for TCP communication on port 3032
* Issues a DNS query to the following domain: r3x.ma7d.com

Files Added

* %WINDIR%\system32\dllcache\mlqm.exe

The worm attempts communication with a server for further instructions. A remote attacker can use the worm to perform various tasks:

Gather system information (CPU, Driver Space, RAM, OS Version, User name, Computer name, IP Address)
SYN Flood others
Kill processes
Download files
Execute files

At the time this was analyzed the worm attempted to SYN Flood various addresses provided by the server.

Indications of Infection

Presence of %WINDIR%\system32\dllcache\mlqm.exe

Unexpected TCP communication on port 3032

Method of Infection

The exact method of propagation will vary between variants. However, the following characteristics are typical:

Share Propagation

*
The worm propagates via accessible or poorly-secured network shares, and some variants are intended to take advantage of high profile exploits:
* DCOM RPC vulnerability (MS03-026) -http://www.microsoft.com/technet/security/bulletin/MS03-026.mspx
* LSASS vulnerability (MS04-011) - http://www.microsoft.com/technet/security/bulletin/MS04-011.mspx

Removal Instructions

All Users:
Use current engine and DAT files for detection and removal.

Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

WordPress founder looks into blogging's future

noreply@blogger.com (Mandy) — Thu, 08 Nov 2007 21:25:00 +0000

LAS VEGAS, Nev.--If you type "Matt" into the Google search bar, you won't immediately get results for the actor Matt Damon or the political site owner Matt Drudge, as you might expect.

Instead, the No. 1 listing points to the site of Matt Mullenweg, the 23-year-old founder of WordPress, the widely used open-source software for blogging.

Befitting his Google ranking, Mullenweg could be considered a superstar here at the BlogWorld conference, where he spoke to hundreds of attendees Thursday about how he started WordPress and the future of blogging. To be sure, when people in the audience were asked if they use WordPress for their personal blogs, a unanimous show of hands went up. Everyone from political to bowling bloggers seemed eager to get Mullenweg's advice on the art of the craft--and how to make money from it.

Mullenweg offered simple pearls of wisdom about what makes a blog compelling.

"One universal about blogging is a lot like music: You have to be unique and you have to absolutely love what you're doing," he said.

Mullenweg started developing WordPress while he was still in college; and he worked on it over several years, including while at CNET, publisher of News.com. Once he left CNET in late 2005, he started the business behind WordPress, called Automattic, which sells blog hosting services and an anti-spam application.

Now, the site draws roughly 100 million unique monthly visitors and is among the top 25 global sites, according to research firm Comscore.

Still, WordPress and Automattic only have 18 employees and they operate from a small investment made in the company more than two years ago, Mullenweg said. How do they fulfill all that demand with 18 people? "Lots of caffeine," he said.

When asked about the future of his business, he answered that he likes the Craigslist model, which as a company has stayed relatively small and does not accept advertising. But he said that he believes there's a way to incorporate ads that are tasteful.

"I would like to stay small but logistically we need many more people on the support side."

Blogs are also one tier in the frenzied social media industry that encompasses Facebook and others. Asked how his software meshes with sites like Facebook, he said he'd like to see more incorporation between the two. Because ultimately, he said, blogs are more telling of a person's personality. That's why he believes Wordpress will become a more popular social network platform, allowing people to post things like widgets of their Facebook profile on a blog or vice versa.

"The software is getting smaller, faster and lighter but what you can do with it is going up," he said.

In the grand scheme of things, Mullenweg said he wants the future of the Web to be open source; and he hopes to get more people using open source platforms to write their blogs, even if it's not WordPress.

But he's obviously driven competitively, too. (His blog ranks No. 1 on Google because of all the links back to his site from WordPress.) He recently saw a survey from Google, in which the search giant examined all of the http headers of Web. He found that .8 percent of those pages were powered by WordPress.

"That's how far we've come, but we have a lot of work to do," he said.

Exploit posted for Viewpoint Media Player flaw

noreply@blogger.com (Mandy) — Tue, 06 Nov 2007 19:25:00 +0000

Exploit code for an unpatched vulnerability in the widely distributed Viewpoint Media Player has been posted on the Internet, putting millions of Internet Explorer users at risk of code execution attacks.
The exploit, available at Milw0rm.com, takes advantage of a stack-based buffer overflow in the Viewpoint browser plug-in that sits on millions of computers thanks to bundling deals with AOL, AIM, Netscape and Adobe.

The player serves as the graphics engine for AOL Instant Greetings, AIM Themes and other popular web applications and is also used to power product tours for the Toyota 4Runner and Sony laptop, desktop, and server computing products.

According to “Shinnai,” the hacker who discovered the flaw, the exploit was tested on a fully-patched Windows XP Professional SP2 with Internet Explorer 7.

The bug was found in the xMetaStream.dll (version 3.3.2.26), which is marked as safe for scripting.

The AxMetaStream activex contains various methods which accept parameters as String. All these methods are vulnerable to a stack based buffer overflow when you pass an overly long (greater than 6999 characters).

In the absense of a patch, Shinnai recommends uninstalling the Viewpoint Media Player.

“Shinnai” was the hacker behind the Month of ActiveX Bugs project.

Bogus FTC e-mail has virus

noreply@blogger.com (Mandy) — Sun, 04 Nov 2007 22:48:00 +0000

The Federal Trade Commission, which has declared war on Internet scams, warned consumers on Monday not to open a bogus e-mail that appears to come from its fraud department because it carries an attachment that can download a virus.
The e-mail says it is from "frauddep@ftc.gov" and has the FTC's government seal.

But it was not issued by the agency and has attachments and links that will download a virus that could steal passwords and account numbers, the agency said.

"It's a treasure trove for identity theft," said David Torok of the FTC's Bureau of Consumer Protection. "We're concerned. The virus that's attached to the e-mail is particularly virulent."

The agency, which is one of several government agencies investigating cyber fraud, did not know how many people had received the e-mail.

"We've received hundreds if not thousands of calls and complaints, this one may have had a large distribution," he said.

Recipients should forward the e-mail to spam@uce.gov, an FTC spam database used in investigations.

Nine percent of people surveyed in a poll conducted in August and September reported having had their identities stolen, Bari Abdul, a vice president at security software maker McAfee, said at a cybersecurity conference on October 1.

Fighting spyware

noreply@blogger.com (Mandy) — Thu, 01 Nov 2007 23:15:00 +0000

Fighting spyware may seem like an uphill battle, but it is a campaign that most of us have little choice but to wage. Over a 15-month period. Microsoft's MSRT alone removed 16 million instances of malicious software from 5.7 million computers, 62 percent of which housed at least one backdoor trojan.
Even the most computer- and security-savvy Internet users occasionally fall victim to spyware. Given the financial gain that drives spyware, these pests will undoubtedly continue to proliferate. For spyware. the best defense is a strong offense: taking reasonable steps to prevent and detect spyware can reduce your risk of compromise and your need for expensive remediation .

The old adage, "An ounce of prevention is worth a pound of cure" certainly applies to spyware. Once spyware has been installed on a host, it can be extremely difficult to return that host to a trustworthy state. Efficient spyware defense starts with proactive steps intended to circumvent popular delivery methods.

Porn Trojan may mark new era for Mac security

noreply@blogger.com (Mandy) — Thu, 01 Nov 2007 21:18:00 +0000

A new piece of malware, specifically designed to exploit Apple's OS X, has been found by Mac security software firm Intego, but Symantec has said the firm is prone to "hype".

Intego issued an alert on Wednesday, warning Mac users of the OSX.RSPlug.A malware, which it describes as a Trojan horse.

The malware is being distributed via a porn site that promotes itself as offering free content. Mac users are being lured to it via links distributed to a number of Mac community message boards.

When visitors attempt to launch the video, they are advised that QuickTime cannot be used and, to view the content, they must download a new version of codec. For the Trojan to be installed, it requires the user to open up the .dmg (disk image) file, click the installer.pkg file, and enter the administrator's password, according to Intego.

If the user does install the Trojan, it changes the user's domain name system (DNS) settings and redirects them to phishing or a number of porn websites. DNS settings are used to look up the correspondence between domain names and IP addresses for websites.

Users of the Mac OS X 10.4 operating system — Tiger — will be unable to see the changed DNS server in the operating system's graphical user interface (GUI). However, those using Mac OS X 10.5 — Leopard — are able to view the changed DNS through its advanced network preferences. The added DNS servers are dimmed in Leopard's GUI, reports Intego.

Intego claims the vulnerability is likely to exist in older versions of Apple's operating system because all versions of OS X have what Intego calls the "scutil command", which allows the DNS server to be altered.

"The Trojan horse also installs a root crontab which checks every minute to ensure that its DNS server is still active. Since changing a network location could change the DNS server, this ensures that, in such a case, the malicious DNS server remains the active server," said Intego on its blog.

For users that do fall for the scam, Intego claims its security software can remove the Trojan. However, Macworld's Rob Griffith has also provided instructions for users on how to manually remove it.

New era or just vendor hype?
Symantec claimed that Intego tends to "overhype things", but Alex Eckelberry, of security firm Sunbelt, disagreed on his blog, citing the firm's resident Mac guru as being "genuinely surprised" by the Trojan discovery.

"I've been using Macs since 1989. This is the first time I've seen something like this," Eckelberry wrote, quoting his colleague.

"I'm not trying to over-hype. Mac users hungry for pr0n really do have to go through a few hoops to get this thing loaded. But we now have millions of new Mac devices out there, between the Touch and iPhone, running OS X," Eckelberry added.

Simon Clausen, director of security vendor PC Tools, agreed the Trojan is a significant milestone for Mac users.

The use of cron tabs — a file that tells the operating system to run commands — is rudimentary, but it's just a first attempt.

"It's the same thing that happened when Vista came out; people had to go through a few steps to get infected, but that was until people figured out a way to get around it. Really, the Mac is less about being a computer than it is about being an everyday device. That's why there's a huge potential for people to target that platform in general. Think how attractive it is to tap the iPhone market that is always on and owned by upper middle-class [users]," said Clausen.

"Anything that's targeted towards Macs is the beginning of Macs becoming a targeted platform. Macs are not impossible to get around. There are probably less known exploits, but they are only less known because fewer people are focusing on the platform," Clausen added.
