A new Trojan known as “Sabpab” could hurt Mac users who run Java and Microsoft Word. Security researchers are warning users to make sure their computers have the latest software updates from both Apple and Microsoft, and to use anti-virus software. In some cases, manual removal of Sabpab may be needed.
Word about Sabpab comes on the heels of another nasty piece of malware, Flashback, that infected up to as many as 600,000 Macs, security experts said, by exploiting a vulnerability in Java software. Apple last week issued a software-base removal tool for that malware, which can be used by criminals to steal personal information, including passwords.

More malware for the Mac OS X platform has been discovered, hot on the heels of the revelation that some 600,000 Macs had been infected in the Flashback attack.
And just like Flashback, the new Trojan doesn’t require any user interaction to infect your Apple Mac.
A malicious and encoded javascript file was found inside the site content and is being used to distribute malware (from newportalse.com and other domains). Any user visiting the infected site could be compromised (desktop antivirus will flag it as JS:Cruzer-B, JS/Obfuscated, JS/Cruzer.C.gen, JS/TrojanDownloader.Agent.NKW and others, depending on the intermediary domains and AV product).
Domains used in this attack:
newportalse.com
(and many others)
Affecting:
Any web site (no specific target).
Clean up:
This malware is generally hidden at the bottom of the .html or javascript files.
Windows 98, Windows 95, Windows XP, Solaris, Windows Me, Windows Vista, Windows NT, Windows Server 2003, Linux, Windows 2000
JS.Alescurf is a detection for malicious code that can be injected in to vulnerable Internet Web pages.

This malicious JavaScript may be injected into legitimate Web pages.
When a user visits the page, the threat gathers certain information from the computer, including:
Computer environment

Recommendations
Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application.
Disable AutoPlay to prevent the automatic launching of executable files on network and removable drives, and disconnect the drives when not required. If write access is not required, enable read-only mode if the option is available.
Turn off file sharing if not needed. If file sharing is required, use ACLs and password protection to limit access. Disable anonymous access to shared folders. Grant access only to user accounts with strong passwords to folders that must be shared.
Turn off and remove unnecessary services. By default, many operating systems install auxiliary services that are not critical. These services are avenues of attack. If they are removed, threats have less avenues of attack.
If a threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread threats, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate compromised computers quickly to prevent threats from spreading further. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
If Bluetooth is not required for mobile devices, it should be turned off. If you require its use, ensure that the device’s visibility is set to “Hidden” so that it cannot be scanned by other Bluetooth devices. If device pairing must be used, ensure that all devices are set to “Unauthorized”, requiring authorization for each connection request. Do not accept applications that are unsigned or sent from unknown sources.
The FBI has issued a warning about the latest identify theft/bank swindling malware, called “Gameover”. The “Gameover” scam is initiated through a phishing scheme that sends fictitious e-mails to a bunch of users from the National Automated Clearing House Association (NACHA), the Federal Reserve Bank, or the Federal Deposit Insurance Corporation (FDIC). After opening the email and selecting the hyperlink, the user is forwarded to a phony website that automatically installs the Trojan without their knowledge or assistance, then eventual access to the victim’s bank account becomes accessible to the scammer.
The scammers used what they call mules to launder the stolen funds by hiring unsuspecting people through the “work at home” advertisements. The hired employees are a work contracts and actual websites to log into. They are instructed to either open a bank account or use their own bank account in order to receive funds via wire and ACH transactions from numerous banks, then they are required to use money-remitting services to send the money overseas.
The “Gameover” Malware is not new; it is a new variant of the notorious Zeus identity-theft Trojan and it capable of defeating common methods of user authentication employed by financial institutions.
In the FBI’s warning stated:
“The malware is appropriately called “Gameover” because once it’s on your computer, it can steal usernames and passwords and defeat common methods of user authentication employed by financial institutions. And once the crooks get into your bank account, it’s definitely “game over.”
Gameover is a newer variant of the Zeus malware, which was created several years ago and specifically targeted banking information.”
The Malware is newer variant of ZeuS malware that steals your Confidential data related to Bank. Not only the malware steals the data but also make your computer as Botnet Slave. A botnet slave can be used to attack a website with Distributed Denial of Service(DDOS).
What make it very dangerous, the Zeus code was released into the wild, so they are many varients such as SpyEye and Ice IX.
Verify your system have been updated to the latest distribution by the Software Vendor.
Verify you have an anti-virus software and that it has been update to the latest signature.
Do not access any links from your bank or entities calming to be affliated with your bank.
If you think you’ve been victimized by this type of scheme, contact your financial institution to report it, and file a complaint with the FBI’s Internet Crime Complaint Center.
