Spammer Banned From MySpace

Technorati Tags: , ,

US District Judge Audrey B. Collins has forbidden Sanford Wallace and his associates from creating or maintaining MySpace profiles, using the site to send private messages or post public comments or to suggest in commercial emails or other electronic communications that that they are affiliated with the social network.

The preliminary injunction came in a lawsuit MySpace filed in March. It claims Wallace created more than 11,000 MySpace profiles that churned out private messages, comments and bulletins that directed users to spoofed MySpace pages seeking their login information.

The ruse allowed him to hijack at least 320,000 accounts, which he used to send 400,000 private messages and post 890,000 comments, both of which redirected MySpace users to the sites freevegasclubs.com and realvegas-sins.com. The sites are owned by Feeble Minded Productions, an aptly-titled firm affiliated with Wallace.

Password Vulnerability in Firefox and Safari

The latest versions of Firefox and Safari contain a password management security flaw that could allow certain websites to access stored usernames and passwords.A message on the Full Disclosure mailing list warned that users who have either browser configured to remember passwords, and have JavaScript enabled, are at risk.

Mozilla fixed a similar reverse cross-site scripting flaw in Firefox last November, but this was a lot more serious as it did not require JavaScript to be enabled.

Heise Security has a demonstration of the vulnerability on its website to allow users to determine whether they are vulnerable to the attack.

However, some developers and commentators have questioned whether this constitutes a vulnerability in the browser, as it requires the attacker to place malicious code on the web server.

If an attacker can place script code on a server, they would be able to manipulate the pages anyway, and would have other ways to steal user access data.

Until a fix is released, users are urged to disable JavaScript in their browser or avoid the use of the password manager on sites where users are allowed to post JavaScript pages.

To disable Java Script in Firefox, go to Tools > Options > Content and untick the Enable Javascript checkbox

To disable Java Script in Safari, go to Preferences > Security > and untick the Enable Javascript checkbox

Winpatrol Gets It's Bark Back

Anyone who knows me will know that I love Winpatrol, one of it’s endearing features has been the little bark that Scotty gives when alerting you to something or when you launch the program.

However… for some reason, Scotty lost his bark on Windows Vista.  But the good news is that Scotty will get his bark back on the next Winpatrol update…. I can’t wait!  Scotty  Woof Woof!

Ransom-ware Trojan is Back

It seems that ransom-ware trojans are coming back into fashion.

Gpcode-AI (AKA Sinowal-FY) encrypts data on compromised machines before demanding money from users to decrypt it. The malware also include backdoor key-logging features designed to pinch confidential bank account and credit card details from compromised PCs.
"This Trojan belongs to the Synowal family, traditionally used to steal passwords and banking details. This variant, however, not only does that, but blackmails users by encrypting their data so that they cannot access it," explained Luis Corrons, Technical Director of PandaLabs.

Blackmail


When Gpcode-AI installs on the system, it encrypts every single document on the hard disk and creates a file called "read_me.txt" with the kidnapper’s demands (obfuscated copy below). Prospective marks are asked to fork out $300 for a tool to decrypt the files.
Hello, your files are encrypted with RSA-4096 algorithm (http://en.wikipedia.org/wiki/RSA).You will need at least few years to decrypt these files without our software. All your private information for last 3 months were collected and sent to us.

To decrypt your files you need to buy our software. The price is $300.

To buy our software please contact us at: xxxxxxx@xxxxx.com and provide us your personal code -xxxxxxxxx. After successful purchase we will send your decrypting tool, and your private information will be deleted from our system.

If you will not contact us until 07/15/2007 your private information will be shared and you will lost all your data.

Glamorous team

The demands falsely claim that payment needs to be made by a set deadline or else data will be unrecoverable. In reality the malware lacks any routine to delete encrypted data and the tactic is a simple ruse designed to speed up payment from victims.

The malware uses a complex encryption algorithm to encrypt user files and archives, making it impossible for victims to open files. But the Trojan uses a modified version of RC4 - and not RSA-4096 as mentioned in the text - to scramble data, according to an analysis by anti-virus experts at Kaspersky Labs. The claim that private user files might be sent to a malicious user is also false.

If this happens to you, please don't pay any money. This will only encourage the crime.. if it is profitable then they will do it. Anti Virus developers are currently working on decryption routines for their databases.

As long as you keep regular backups of your essential data then a reformat won't be a problem for you. If you have never considered a backup before now then here is a link to get you started.

Windows Vista Drivers

Drivers for Windows Vista have been a bit of a problem since the Beta version was released last year. A friend of mine couldn’t wait to try it out, but he just couldn’t fix the problem he had with finding a compatible sound driver.

Things are a bit better now, but hardware manufacturers are still taking their time updating their drivers so that your kit will play nice with Vista.

Of course, finding the right driver is the difficult bit. Ed Bott has set up a Vista Master Driver List so if you can’t find it there then it’s probably not been released yet. Thanks to Ed for a great resource and thanks to Corrine of Security Garden for the tip… she’s added this list to Vista Bookmarks which is another site you should check out regularly.

QuickTime Update Fixes Eight Flaws

Apple has released a new version of its ubiquitous QuickTime player for both Mac OS X and Microsoft Windows computers. The latest version, v. 7.2, plugs at least eight security holes in the software.

QuickTime vulnerabilities that span both operating systems may present a very attractive target for malicious hackers, as the program is installed by default on all Apple machines, and on most Windows PCs (if you have iTunes installed, chances are you also have QuickTime on your system). Indeed, recent automated attack tools have been found to exploit QuickTime flaws.

Mac users can grab the latest, patched version using the built-in Software Update feature. Windows users should be able to fetch the patches using the Apple Software Update program that comes bundled with most relatively recent versions of QuickTime and iTunes.

Flash Player Update

There has been a Flash Player update that addresses two security vulnerabilities.

Adobe Security Bulletin

Please note; You don't have to have the Google Toolbar to install the update so just uncheck it.

Talking of Adobe, there are also some Photoshop CS2 and CS3 updates to address security vulnerabilities.

Mozilla Firefox Multiple Popup Tabs Denial of Service Vulnerability

 Firefox is prone to a remote denial-of-service vulnerability.

An attacker may exploit this issue by enticing victims into opening a maliciously crafted HTML document.

Successful exploits can allow attackers to crash the affected browser, resulting in denial-of-service conditions.

Firefox 2.0.0.4 is vulnerable to this issue; other versions may also be affected.

Hosts File Update

The MVPS Hosts File was updated yesterday.

What is a hosts file? It's a very useful piece of kit that sits in a little folder not bothering anyone. When you tell your browser that you want to go to a particular website, the browser will convert the address you typed to a bunch of numbers called an IP address, before it connects to the website it will check the hosts file to make sure it's got the numbers right. If there is nothing there, then it will connect.

That seems straight forward enough, but why have a hosts file when your browser always goes where you want it to go.. well if you think about it, sometimes it doesn't. Lots of websites have adverts on them.. some of these ads try to connect to a separate server so they can dump a tracking cookie into your system. Or, maybe you are searching for something and inadvertently click on a link to a bad site which could infect your computer with something horrible. This is where the hosts file comes into it's own. If you have an entry in your hosts file like this;

127.0.0.1 www.thisisnotasiteyouwanttovisit.com

Then if your browser tries to connect to thisisnotasiteyouwanttovisit.com, when it checks the hosts file it will just come back on itself because the IP 127.0.0.1 is your computer.

So... a hosts file is a very useful security feature to have on your computer, it's not much good though if it isn't kept up to date. The MVPS hosts file is updated regularly. See mvps.org for more information, tips and installation instructions.

Panda NanoScan

Did you know about this? It's an online scanner from Panda, but unlike some online scanners this one just takes a minute or two.

It claims to detect more than 1,031,124 virus's and spyware.

You do need to download and install an ActiveX to run it and therefore Internet Explorer is recomended, although if it's Firefox or nothing for you then you can install the IEtab addon to run it.

Nanoscan only detects and it's recomended that you run TotalScan if anything is found.
Here is the science bit .

Don't forget, there are other online scanners available and you should always have an active and up to date resident anti virus program on your system.
