The H-Online: Tor developers Arturo Filasto and Jacob Appelbaum have been working on a new tool they call the OONI-probe. OONI stands for Open Observatory of Network Interference and is designed to help map internet censorship across the global network. The open source tool gives users the ability to check their internet connection for censorship, selective bandwidth throttling, surveillance and other interferences. This data can then be shared freely with other users, creating a global overview of the state of censorship of the network. ...

The H-Online: According to a blog post, a modified version of the Skype VoIP software can be used to easily find out the IP address of any valid Skype user. No contact has to be made with the user in order to get the information. This IP could then be used to find out other personal details about the user, such as their location or even their employer. With a certain registry key, the manipulated version of Skype will create a log file with information including other users’ external and internal IP addresses. These IPs can be retrieved simply by opening up a user’s profile with the Skype client. In a test conducted by The H’s associates at heise Security, the log file always showed the correct IPs – and when a user was logged in with multiple clients, the IP addresses for all the clients were visible. ...

The H-Online: The whitec0de.com blog reports that, for $20, a member of a hacker forum offered to crack any Hotmail account within a minute – and that he kept his word. Apparently, the hacker found out about a critical vulnerability in Microsoft’s email service on a security forum, and the hole allowed him to change the passwords of arbitrary Hotmail users. The blog says that various users were affected as a result, for example because they used their Hotmail accounts to access services such as PayPal. Allegedly, the vulnerability was also exploited to change the ownership of particularly attractive, short account names such as [email protected] and [email protected]. ...

The H-Online: Online forums have, for some time, apparently been the target of hackers who inject additional code. However, the attackers aren’t interested in publishing cool slogans or political messages, they’re looking for money. They steal Google traffic from the forums and exploit this traffic via ads. Their main targets appear to be forums that are based on the vBulletin software. Unlike the “Look how cool I am” crackers, these attackers have very discreet working methods. They hide their code deeply within the system and ensure that their redirections don’t attract much attention. Only users who visit forum pages for the first time via a search engine such as Google are redirected to a url123.info URL. This site initially displays a strange blocking alert (“Access denied”) followed by some arbitrary text and then loads a full-page ad by InfinityAds. The ads are probably a direct source of income for the intruders even though each ad is only worth a few pennies. However, as some forum operators have reported that their traffic has dropped by more than 70 per cent, and the phenomenon seems to be a rather wide-spread one, the overall yield is likely to be considerable. ...

The H-Security: The head of Google’s Webspam team, Matt Cutts, announced on Twitter that Google has sent out a message to the webmasters of 20,000 sites informing them that their sites may have been hacked. In the email message, the company warns operators that the affected sites appear to be being used to redirect visitors to a malicious site. Google asks the site administrators to check the files in their web space for an eval(function(p,a,c,k,e,r) JavaScript code segment. The eval() function can be used to execute JavaScript character strings that may have previously been decrypted using an unpack feature. Google also warns of specially crafted .htaccess files. These may cause a file to be redirected only in certain circumstances, for example, when a visitor accesses the page via Google. Consequently, regular visitors to a site, such as the webmaster, will be unaware of the infection. ...

As I said in the other post, Iran’s Central Bank has announced that the electronic information of 3 million customers of 10 Iranian banks have been compromised. These banks now require their customers to change their ATM pin numbers before they can access their account. This has caused a rush to the ATM machines by the worried customers. The hacker was identified as Khosro Zare’, a former bank-system specialist in Iran who recently left the country. Zare’ claimed in a blog that he hacked the PIN codes to highlight the vulnerability of Iran’s banking system. ...

SophosLabs: 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. The Sabpab Trojan horse exploits the same drive-by Java vulnerability used to create the Flashback botnet. The newly discovered Sabpab malware is in many ways a basic backdoor Trojan horse. It connects to a control server using HTTP, receiving commands from remote hackers as to what it should do. The criminals behind the attack can grab screenshots from infected Macs, upload and download files, and execute commands remotely. ...

Malware blocks booting

Anti-virus experts at Trend Micro have discovered ransomware which blocks systems from booting. In contrast to the localised trojans, which are widely spread around Europe, it does so by inserting itself into the master boot record (MBR). It then restarts the system and instructs the user to pay a ransom of 920 Ukrainian hryvnia (equivalent to about 90 euros) to the criminals via payment service QIWI. If victims pay up, the criminals send them a code to unlock their computers. Users can, however, save themselves 920 hryvnia by following the experts’ instructions for removing the infection. This essentially consists of running the recovery console from the Windows Installation DVD and restoring the original MBR using the fixmbr command. ...
