Phish campaign targets users - timed with breach...
- http://nakedsecurity...shing-campaign/
December 14, 2011 - "A phishing campaign targeting customers of Telstra Bigpond, Australia's largest ISP, is urging users to confirm their billing information or risk the suspension of their account... All pretty run-of-the-mill - an access your account now by clicking on a link in this email or else spam - but neatly timed given that Telstra suffered a data breach last Friday. Personal information... was downloaded from an insecure Telstra customer portal last Friday (I have read numbers from 60,000 to 70,000), forcing Telstra to take down some of its services, including webmail, over the weekend. Ironically, the forced outage also prevented access to the Bigpond account management pages, making it hard for concerned users to change their passwords as a precaution against abuse, or, indeed, to check their account and billing information... an unpatched version of WordPress allowed the phishers to "borrow" services from an Aussie blogger... this email was obviously a phish:
- Bigpond doesn't send out access your account now by clicking on a link emails.
- The email contains numerous errors of orthography, spelling and grammar. Official Bigpond emails are professionally written.
- The link you are asked to click on has no obvious connection with Telstra or Bigpond.
- Official Bigpond emails to you aren't addressed to someone called "Duchess" with a competitor's webmail account (unless your name is Duchess, of course).
... if you run a WordPress blog, make sure you've applied the latest patches. Vulnerable blog sites can be a gold mine for cybercrooks."

Ransomware impersonates the police
- https://blogs.techne...Redirected=true
19 Dec 2011 - "... several samples of a ransomware family localized into different languages... We've so far seen variants localized into four languages: English, Spanish, German, and Dutch... Upon execution, the ransomware locks the computer, displays the localized screen.. and demands the payment of a "fine" for the supposed possession of illicit material. In order to make the computer functional again, the user is asked to transfer money via a legitimate online payment service, such as Paysafecard or Ukash, to the supposed authorities. These services are -not- involved in any way with the scammers' scheme; instead, they are being used for malicious purposes... In the case of Trojan:Win32/Ransom.DU... that impersonates the German Federal Police, 91.59% of the samples we received from July to November this year were found in Germany... this localized ransomware family can be distributed through drive-by downloads and that the Blackhole Exploit Kit is involved... nowadays Blackhole distributes many widespread malware families...

Email Bank Deposit Scam

12/19/2011 - "USAA's Enterprise Security Group has found an aggressive email phishing scam directed at USAA Members. The email has a subject line "Deposit Posted." What makes this particular phishing email different is there is a randomly generated four-digit number placed in the USAA Security Zone section... While this email* does not ask the recipient to click on a link, it does ask the member to open an attached file. When this file is opened it launches a malicious banking virus that if successfully launched could provide access to your personal information and may require a complete reinstall of your computers operating system.
What Members Should Do:
USAA Members are encouraged to take the following action if they receive this email:
Make certain the four digits in the Security Zone section match the last four digits of your USAA member number.

.nl.ai?
- https://isc.sans.edu...l?storyid=12280
Last Updated: 2011-12-28 00:51:54 UTC - "Now .. where is nl.ai ?? Dot-ai is Anguilla, a speck of land in the Caribbean, to the east of Puerto Rico. And probably has nothing at all to do with what follows. Dot-nl-dot-ai, on the other hand, appears to be a free domain name registrar.
If you're into malware analysis, you've probably seen your fair share of .nl.ai domains recently. And not just these. Feeding "nl.ai" into RUS-CERTs Passive DNS collector http://www.bfk.de/bf...s1.cd.am#result gives us the name server for .nl.ai (one ns1.cd.am), which in turn shows a couple of other domains that are currently very familiar to the malware analyst. Like .c0m.li, and .cc.ai.
If you are blocking domains on your gateway or DNS server, blackholing these few:
.cc.ai
.nl.ai
.c0m.li
.cd.am
.coom.in
... might be a reasonable move, at least until someone in your business can show that they have a legitimate need to access one of the sub domains of these pseudo top level domains. Mind you, chances are that not all domains hosted there in fact are bad. But all the ones that I've seen in my logs so far: were."

Dec 29, 2011 - "... QR codes, hackers are starting to take advantage of these square, scannable bar codes as a new way to distribute malware. Like all mobile attack vectors, it is a new frontier that security researchers say is not extremely prevalent but which has a lot of potential to wreak havoc if mobile developers and users stand by unaware... Just point your mobile device's camera on the code, scan it and the reading will take you to the website or mobile app download that its promoter promises to provide... There are a number of ways they are already using malicious codes to perpetrate their scams. On iOS devices, for example, hackers are re-purposing jail-break exploits to send users to websites that will jailbreak the device and install additional malicious malware... attackers are using QR codes to redirect users to fake websites for phishing..."

Web hijacks with AJAX
- http://labs.m86secur...acks-with-ajax/
January 3, 2012 - "... a malicious site which loads parts of its attack using AJAX (Asynchronous JavaScript and XML), a method for client-side code to asynchronously exchange data with web servers. The following attack was observed on a currently running server located in China, which is serving malware... This code is very similar to code commonly used in so many web pages nowadays. The main difference is the extra parameters it accepts, which are used to “cut” certain parts from the accepted content, so it could be processed and executed as code later on... Using the exact same technique, this web page can load various browser or plugin exploit attempts. In this specific case, the page loads an SWF file exploiting CVE-2010-1297. Other pages on this server are exploiting CVE-2010-0806 and CVE-2010-0249. The main reason that malware authors use AJAX is the ability to write generic attack pages which look benign and become malicious only once the dynamic content is loaded. This provides an advantage which is also very useful for evading AV detection, since tiny bits of the attack can be loaded one at a time, thus making it very difficult to provide a signature..."

There is another, less discussed, form of man-in-the-browser attack – the post transaction attack... as the name implies, occur after the evil deed has already been done and the account holder has closed the online banking session. These are designed to conceal illegitimate activity for as long as possible to either allow money to transfer to its final destination – uninterrupted, or continue to control the account and perform further transactions... Just before the recent holiday season, we came across a SpyEye configuration which attacks banks in the USA and UK. Instead of intercepting, or diverting, email messages... the attack automatically manipulates the bank account transaction webpage the customer views... a post transaction attack is launched that hides fraudulent transactions from the victim..."

Worm on Facebook steals 45,000 logins ...

January 5, 2012 - "... Seculert's research lab has discovered that Ramnit recently started targeting Facebook accounts with considerable success, stealing over 45,000 Facebook login credentials worldwide, mostly from people in the UK and France... Recently, our research lab identified a completely new 'financial' Ramnit variant aimed at stealing Facebook login credentials. Since the Ramnit Facebook C&C URL is visible and accessible it was fairly straightforward to detect that over 45,000 Facebook login credentials have been stolen worldwide, mostly from users* in the United Kingdom and France...
* http://1.bp.blogspot...itbycountry.png
... We suspect that the attackers behind Ramnit are using the stolen credentials to log-in to victims' Facebook accounts and to transmit malicious links to their friends, thereby magnifying the malware's spread even further. In addition, cybercriminals are taking advantage of the fact that users tend to use the same password in various web-based services (Facebook, Gmail, Corporate SSL VPN, Outlook Web Access, etc.) to gain remote access to corporate networks... With the recent ZeuS Facebook worm and this latest Ramnit variant, it appears that sophisticated hackers are now experimenting with replacing the old-school email worms with more up-to-date social network worms. As demonstrated by the 45,000 compromised Facebook subscribers, the viral power of social networks can be manipulated to cause considerable damage to individuals and institutions when it is in the wrong hands..."
