Corporate account credentials phished…
- http://www.finextra.com/news/fullstory.aspx?newsitemid=22957
16 September 2011 - "The FBI is currently investigating over 400 reported cases of corporate account takeovers, where cyber crooks have used ACH and wire transfers to steal tens of millions of dollars from US businesses. The scale of the problem was revealed this week by the bureau's assistant director in the cyber division, Gordon Snow, in testimony to a House Financial Services Committee subcommittee. Smart says business employees are being targeted by phishing e-mails containing infected files or links to suspect Web sites, enabling criminals to install -malware- on their computers to harvest online banking credentials. The FBI is looking in to over 400 cases where crooks have used this information to steal money from firms' accounts, involving the attempted theft of over $255 million and the actual loss of around $85 million…"

Clicking the adverts takes end-users to sites such as river-park(dot)net, and they do a pretty good job of convincing visitors that these sites are the real deal (incidentally, you'll notice that some of the ads display the "real" URL of the program mentioned, but take you to a rogue site such as the "Download uTorrent Free" advert… which actually takes you to aciclistaciempozuelos(dot)es/torrent)… All of the malicious downloads are coming from en-softonic(dot)net… the fake Firefox file installs a rootkit, runs IE silently in the background attempting clickfraud and also performs Google redirects. Current VirusTotal score for that one is 16/44*, and we detect it as Win32.Malware!Drop. These adverts were also appearing in Yahoo search - we notified both Yahoo and Microsoft, and both companies are in the process of killing these things off.

The emails even formally claims that legal action will be taken because of the spam you have sent. These emails with the fake warning even attach a ZIP file that contains a scanned copy of a document that is supposed evidence of your spam… The spam outbreak uses several alerting subject headings to attract readers' attention. The ZIP file is actually an EXE file disguised as a document after decompression. It's a kind of Trojan.Downloader virus confirmed by VirusTotal*. When the trojan triggers, it copies itself to the system path under the Startup folder and deletes itself. Whenever you start the computer, the trojan will execute. This trojan can connect to remote servers and download malicious files… This campaign could potentially contain other variants of the trojan as attachments…"

Fake transfers are latest Bank Heist …
- http://www.trusteer.com/blog/fictitious-tr…test-bank-heist
September 20, 2011 - "A number of banks, in an effort to validate and secure financial transactions, are utilising transaction verification systems. They’re doing this in the belief that, even if malware manages to change transaction details on the fly, the customer has an out of band channel to verify that it has not been modified. This is based on the assumption that malware cannot infect the out of band channel, and therefore the bank or the customer will be able to detect fraudulent transfers… the assumption that malware cannot influence the out of band channel is flawed. The easiest way to defeat transaction verification systems is using social engineering attacks. Over the years we've seen a number of different variants against transaction verification systems… Using malware fraudsters first gain control over the web channel. This means -any- information that customers view inside their browser, while connected to their bank, can be modified by the fraudsters. Unfortunately, customers are usually -unable- to distinguish whether what they are seeing was actually served by the bank, or in fact modified by malware! This is giving fraudsters the ability to launch extremely effective social engineering attacks. In the attack we've recently seen, fraudsters were simply waiting for customers to log on to their bank's website. The bank robber then ‘changed’ the content of the post login page, to a message, informing customers of an upgraded security system. The customer is invited to go through a training process that intends to help him/her deal with the bank's upgraded security system. As part of the training they’re asked to make a transfer, to a fictitious bank account, and confirm the transaction using the confirmation code that is sent by the bank to the registered mobile phone. Fraudsters claim that the user's account will not be debited and the recipient's account is fabricated… the transaction then happens, the money is transferred, and the criminal disappears off into the sunset…"

Japan - MHI hacked …
- http://www.itpro.co.uk/636271/japan-attack…y-cyber-war-now
21 Sep 2011 - "… Mitsubishi Heavy Industries, one of Japan’s major weapons suppliers, admitted 45 of its servers and 38 computer terminals were infected. Targeted malware was allegedly used as part of a spear phishing attempt – similar to other attacks that have attempted to breach Governments in recent times, including in the UK. RSA was compromised by such tactics too – another situation in which some suspected a nation state’s involvement, as at least one of the eventual targets turned out to be major US defence contractor Lockheed Martin… In the case of MHI, no one has yet claimed responsibility for the infection. China, the number one suspect according to some sources, has denied any involvement. As with so many recent cases, no nation has been found guilty, nor has any Government admitted to being the perpetrator of an attack. When the DigiNotar attacks emerged last month, eventually resulting in the certificate authority’s demise, many pointed fingers at Iran. Yet in that case, ComodoHacker claimed responsibility, saying the Iranian regime had no hand in the hacks. For any onlookers, it’s near to impossible to know whom to trust. There is just too much obfuscation and potential for covert behaviour to lump any event under the ‘cyber war’ umbrella… As information remains a hugely valuable commodity, and hacking becomes an increasingly useful tool for acquiring it, cyber war will still focus heavily on data, rather than causing real-world havoc. Both public and private organisations will therefore be targets… individuals will be affected. There will be civilian casualties too, in the data sense at least…"

Fake "browser update" worm …
- http://www.malwarecity.com/blog/update-you…-pass-1155.html
23 September 2011 - "… As the DNS infrastructure is well defended against attacks, cyber-crooks often try to mess with the local DNS settings. This is the case of the infections with Worm.Rorpian.E that, once it successfully infects a computer on the network, starts acting as a DHCP server (an application that manages the connectivity of the network computers) and tampers with the local DNS servers to resolve all the requests to a rogue IP in Romania…
If you give in to the demand and “update your browser”, you’ll get infected with the same Worm.Rorpian.E, and your PC will start acting like a rogue DHCP server for the other clients connected to your network. Once the user clicks the “browser update” button, a php script fetches the malware from the server and names it as updbrowser[date].exe, where date is the current year, month and day. Of course, since we’re talking about cybercrime, the infection wasn’t only designed for fun. Once your PC has been infected with the “browser patch”, the worm starts bringing its friends to the party, cloaked by the infamous TDSS rootkit. Rorpian also has secondary spreading mechanisms: it “jumps” via network shares, exploits a couple of old, critical vulnerabilities such asthe .LNK (MS10-046) and the one in the Windows DNS RPC Interface (MS07-029) to download and execute further malware onto the infected PCs…"

This domain hosts the BlackHole exploit pack. It exploits the visitor's browsing platform (the browser, the browser plugins like Adobe Flash, Adobe PDF, etc, Java, …), and upon successful exploitation, permanently installs a piece of malware into the visitor's machine, without the visitor's knowledge. The visitor doesn't need to click or agree to anything; simply visiting mysql .com with a vulnerable browsing platform will result in an infection.
Currently, 9 out of 44 vendors on VirusTotal* can detect this piece of malware."

2011-09-27 - "When a Microsoft Windows machine gets infected by viruses/malware it does so mainly because users forget to update the Java JRE, Adobe Reader/Acrobat and Adobe Flash… CSIS has over a period of almost three months actively collected real time data from various so-called exploit kits. An exploit kit is a commercial hacker toolbox that is actively exploited by computer criminals who take advantage of vulnerabilities in popular software. Up to 85 % of all virus infections occur as a result of drive-by attacks automated via commercial exploit kits. The purpose of this study is to reveal precisely how Microsoft Windows machines are infected with the virus/malware and which browsers, versions of Windows and third party software that are at risk. We have monitored more than 50 different exploit kits on 44 unique servers/IP addresses… The statistical material covers all in all more than half a million user exposures out of which as many as 31.3 % were infected with the virus/malware due to missing security updates… On the basis of the total statistical data of this study it is documented that following products frequently are abused by malware in order to infect Windows machines: Java JRE, Adobe Reader/Acrobat, Adobe Flash and Microsoft Internet Explorer… The conclusion of this study is that as much as 99.8 % of all virus/malware infections caused by commercial exploit kits are a direct result of the lack of updating five specific software packages*…"

30 September 2011 - "Nominet, the .uk address registry, has suspended hundreds of internet domain names as part of a global police crackdown on crime gangs peddling fake pharmaceuticals. Operation Pangea IV saw almost 13,500 websites taken down and dozens of suspects arrested in 81 countries, according to Interpol, which coordinated the swoop. Over 2.4 million potentially harmful counterfeit pills, worth about £4m, were seized in raids between 20 and 27 of September, Interpol said. Confiscated medicines included everything from diet pills to anti-cancer drugs. Cops worked with customs agencies, ISPs, payment processors and delivery companies to close down the allegedly criminal operations, Interpol said. In the UK, Nominet acted upon advice given by the Medicines and Healthcare products Regulatory Agency and the Police Central e-Crime Unit to suspend about 500 .uk domains.."

Facebook malvertisement leads to Exploits

Oct. 4, 2011 - "… We encountered an infection chain wherein the user is led from a page within Facebook to a couple of ad sites then, finally, to a page that hosts exploits. When we traced the connection between the ad sites and Facebook, we found that the ad providers were affiliated with a certain Facebook application. We checked out the said application and found that it is indeed ad supported. We were able to come up with the likely infection chain… Upon accessing the application, the malvertisement gets loaded, triggering a series of redirections. The redirections finally lead to a malicious site, which then loads several exploits, particularly those related to Java and ActiveX:
