Launching in 2015: A Certificate Authority to Encrypt the Entire Web

The Citadel Trojan has once again branched out beyond its roots as banking malware and is now targeting the master passwords guarding major password management products. Researchers from IBM Trusteer today said they’ve notified makers of the nexus Personal Security Client, Password Safe and KeePass about a new configuration file found on an infected computer targeting processes used by the respective password management tools. Tamir said the Personal.exe process in nexus Personal Security Client, PWsafe.exe from Password Safe and KeePass.exe are called out by the new Citadel configuration files. In each case, the malware seeks out and captures the master password that unlocks the password database stored by the password management tool. NeXus Personal Security Client is cryptographic middleware used in enterprise and service provider locations to secure financial transactions, ecommerce and other services from the desktop. Password Safe, meanwhile, is an open source tool built by Bruce Schneier. KeePass is also a free, open source password manager, but it uses a random password generator preventing the user from having to come up with individual passwords. The Trojan, however, sidesteps that protection by stealing the master password. Tamir could not confirm whether these are opportunistic or targeted attacks. IBM said it has notified the respective vendors in order that users might be notified as well. Citadel, like most widely distributed malware families, is crossing over more and more from the realm of cybercrime to APT-style targeted attacks. New features and a hunger for legitimate credentials make the malware, which is already sitting on hundreds of thousands of machines, particularly dangerous to critical infrastructure, in addition to financial services. In September, a Citadel variant was used in attacks against petrochemical companies in the Middle East. IBM said at the time that the repurposed versions of Citadel were going after email credentials in order to phish others within an organization or gain deeper access to a compromised network. Tamir estimates that one in 500 computers is infected with malware used in targeted APT attacks. Citadel can sit dormant on an infected computer until a user lands on a particular site; depending on how the malware is configured, it can be triggered by visiting a specific online banking site or web-based email log in.

WhatsApp has turned on an encryption system to protect messages sent with the Android version of its app. The WhatsApp Android application has been downloaded about 500 million times. It said the data scrambling system should make it much harder to eavesdrop on the messages users exchange. Tech firms have faced criticism by law enforcement figures who said greater use of encryption made it harder to track criminals and extremists. Data scramble The encryption system being applied to WhatsApp is called TextSecure and has been developed by a non-profit group called Open Whisper Systems. Unlike other encryption systems, which often scramble messages only as they travel from a device to the servers that companies use to route them to their recipients, TextSecure keeps the encryption intact throughout a message's journey from handset to handset. Initially the encryption is being applied only to messages sent via the Android version of WhatsApp. Soon it will be extended to group messages, photos and videos sent via the Android app. Open Whisper said it also planned to develop versions of TextSecure that work with WhatsApp apps on other smartphone operating systems but did not give a date for when those would be ready. Facebook acquired WhatsApp in a deal worth $22bn (£14bn) The tie-up marks a huge boost in the numbers of people using TextSecure, which had reached about 10 million, mainly people who had installed the Cyanogen variant of the Android operating system. WhatsApp said the encryption system would be turned on by default for its huge number of Android users. In October, Facebook completed a $22bn (£14bn) acquisition of WhatsApp. In a separate development, the Electronic Frontier Foundation, which campaigns on digital rights, has unveiled a project to make it easier and cheaper for smaller organisations and websites to use strong encryption. Called Let's Encrypt, the initiative aims to produce software tools that automate, as much as possible, the process of using the web's standard encryption systems. Many sites and organisations shy away from adopting these technologies because they can be technically demanding to install and administer, said Peter Eckersley, EFF technology projects director, in a statement. Let's Encrypt has been set up with the help of Mozilla, Cisco, Akamai and others and aims to launch in 2015. Both moves could anger intelligence and law enforcement agencies, which have criticised tech firms for their greater use of encryption. Source

Today I was brought to the attention of a Tumblr post - apparently there's malware doing the rounds making use of Steam chat, (adding Steam friends and) spamming Steam users. Example message: Onyx is right, the link's indeed phishy and uses bit.ly (a URL shortener) to trick users into clicking it. Remember the worm that spread via Skype and Messenger last year? (reference here and here) This is a similar campaign. Setup Someone adds you on Steam, you accept and immediately a chat pops up as similar to above. Alternatively someone from your friends list already got infected and is now sending the same message to all his/her friends. The bit.ly link actually refers to a page on Google Drive, which immediately downloads a file called IMG_211102014_17274511.scr, which is in fact a Screensaver file - an executable. The file is shared by someone named "qwrth gqhe". Looks legit. Note that normally, the Google Drive Viewer application will be shown and this will allow you to download the .scr file. In this case, the string "&confirm=no_antivirus" is added to the link, which means the file will pop-up immediately asking what to do: Run or Save. (and in some cases download automatically) At time of writing, the file is actually still being hosted by Google Drive. I have reported it however. Afterwards, you're presented with the screensaver file which has the following icon: Opening the file will result in installing malware on your system, which will steal your Steam credentials. Technical details: Downloads and executes: Remediation What if you clicked the link and executed the file? Follow these steps: Exit Steam immediately Open up Task Manager and find a process called temp.exe, wrrrrrrrrrrrr.exe, vv.exe or a process with a random name, for example 340943.exe Launch a scan with your installed antivirus Launch a scan with another, online antivirus When the malware has been disinfected or deleted, change your Steam password - if you use the same password for other sites, change those as well Verify none of your Steam items are missing Prevention Be wary when someone new adds you on Steam and immediately starts sending links In fact, don't click on links someone unknown sends to you If you did, don't open or execute anything else - just close the webpage (if any) or cancel the download By default, file extensions are not shown. Enable 'Show file extensions' to see the real file type. Read how to do that here Add the IP 185.36.100.181 to your host file or block it in your firewall. In the host file, add: 127.0.0.1 185.36.100.181 Follow the tips by Steam itself to further protect your account: Account Security Recommendations Conclusion Never click on unknown links, especially when a URL shortener service like bit.ly is used. (others are for example t.co, goog.gl, tinyurl, etc.) Don't be fooled by known icons or "legit" file descriptions, this can easily be altered. Even if you clicked the link and you're not suspicious, you should be when a file is downloaded and it's (in this case) a screensaver file.

Au fost prinsi cei care au "spart" site-ul IGPR
Aerosol replied to D--ABLO's topic in Stiri securitate
Frate sa fim seriosi adica majoritatea parintilor nu stiu sa umble pe internet si cacaturi. Degeaba ii invata ceva parintii daca ei fac altceva nu sunt ei de condamnat, plus ca astia au fost si idioti nu au stiut sa se protejeze, daca faci un cacat iti iei anumite masuri de siguranta dar pula mea, noul val de "hackeri" Oricum nu are rost sa o lungim aiurea, concluzia sunt doar niste retardatii ce si-au primit pedeapsa (sau o vor primi). -
