A vulnerability has been discovered in the wildly popular Google's Stock Android Email App , that could be exploited by malicious attackers to remotely crash your smartphone application just by sending a specially crafted email. A Spain security researcher, Hector Marco , successfully exploited the vulnerability on his Samsung Galaxy S4 Mini running version 4.2.2.0200 of Stock Android Email App. He said the flaw appears to affect all older versions of Stock Android Email App, though devices running 4.2.2.0400 and newer versions are not affected. According to the researcher, when the victim receives the malicious email and tries to view it, the email app crashes. Further attempts to open the email again triggers a crash in the application before the victim can do anything. The flaw ( CVE-2015-1574 ) is due to incorrect handling of the Content-Disposition header . Hackers could exploit the vulnerability by sending an email with a malformed Content-Disposition header to th

Security researchers have disclosed local zero day DLL hijacking vulnerabilities in several applications developed by Corel Software that could allow an attacker to execute arbitrary commands on victims' computer, potentially affecting more than 100 million users. The security holes were publicly disclosed by Marcos Accossatto from a vulnerability research firm Core Security after the vendor didn't respond to his private disclosure about the flaws. Corel develops wide range of products including graphics, photo, video and other media editing programs. According to the researcher, when a media file associated with one of the vulnerable Corel products is opened, the product also loads a specifically named DLL (Dynamic Link Library) file into memory if it's located in the same directory as the opened media file. These DLL files contain executable code which could allow an attacker to install malware on victims' computers by inserting malicious DLLs into the

A German Security researcher has demonstrated a critical  vulnerability on Ebay website, world's biggest eStore. According to David Vieira-Kurz  discovered Remote code execution flaw " due to a type-cast issue in combination with complex curly syntax ", that allows an attacker to execute arbitrary code on the EBay's web server. In a demo video, he exploited this RCE flaw on EBay website, and managed to display output of phpinfo()  PHP function on the web page, just by modifying the URL and injecting code in that. According to an explanation on his blog , he noticed a legitimate URL on EBay: https://sea.ebay.com/search/?q=david&catidd=1  . . and modified the URL to pass any array values including a payload: https://sea.ebay.com/search/?q[0]=david&q[1]=sec{${ phpinfo() }}&catidd=1 Video Demonstration: But it is not clear at this moment that where the flaw resides on Ebay server, because how a static GET parameter can be converted to accept like an array

Google has recently removed a Rogue Android gaming app called " Balloon Pop 2 " from its official Play store that was actually stealing user's private Whatsapp app conversations. Every day numerous friends ask me if it is possible to steal WhatsApp chat messages and how, of course a malware represents an excellent solution to the request. In the past I already posted an article on the implementation of encryption mechanisms for WhatsApp application explaining that improper design could allow attackers to snoop on the conversation. Spreading the malware through an official channel the attacker could improve the efficiency of the attack, and it is exactly what is happening, an Android game has been published on the official Google Play store to stealthy steal users' WhatsApp conversation databases and to resell the collection of messages on an internet website. The games titled " Balloon Pop 2 " has been fortunately identified and removed from the official Google Play

A Mysterious Hacker who goes by the " Pinkie Pie " handle is rewarded with $50,000 USD for hacking into the Google Chrome browser for Nexus 4 and Samsung Galaxy S4 . At Information Security Conference PacSec 2013 in Tokyo, during the HP's Pwn2Own contest, a zero-day exploit  showcased by " Pinkie Pie ", that took advantage of two vulnerabilities: An integer overflow that affects Chrome. Chrome vulnerability that resulted in a full sandbox escape. For successful exploitation, you have to get your victim to visit a malicious website e.g. clicking a link in an email, or an SMS or on another web page. He demonstrated this zero-day attack with remote code execution vulnerability on the affected devices. It is not known whether other Android phones are also vulnerable to same flaw or not. Vulnerability has been disclosed to Google by the Contest organizers and the company is working to address the issue as soon as possible. Researchers from

Bitcoin Talk , the popular Bitcoin discussion forum, has been hacked and as it stands the site is currently unreachable. Bitcointalk has been down for nearly 6 hours. The forums have been allegedly hacked and Defaced by " The Hole Seekers " and selling 150,000 emails and hashed passwords stolen from Bitcointalk.org for 25 Bitcoins , where the passwords are hashed with sha256crypt. Hacker embedded the "1812 Overture" song in the background with a dazzling animated picture show. According to Bitcointalk admin Theymos, it's possible that the hackers gained access to the database. He says the website will not be restored until he figures out precisely what vulnerability the hackers leveraged. He's offering 50 Bitcoin to the first individual who can pinpoint the security hole. See the video below for the Hack-in-Action: " Hello friend, Bitcoin has been seized by the FBI for being illegal. Thanks, bye " reads one the message in the video. To be safe, it is reco

A Georgia Tech researcher has found a weakness in Apple's iOS mobile platform that could let hackers to hide malicious code inside apps and can be surreptitiously planted on the Apple App Store. Researchers team created a proof-of-concept attack that was published in the Apple App Store and used to remotely launch attacks on a controlled batch of devices , enabling them to post unauthorized tweets, take photos and even go after other apps. " Our research shows that despite running inside the iOS sandbox, a Jekyll-based app can successfully perform many malicious tasks, such as posting tweets, taking photos, sending email and SMS, and even attacking other apps all without the user's knowledge. " Using a BeagleBoard, team created a USB malicious charger called Mactans  that can install apps without user knowledge within a minute of being plugged in. In one demonstration, the attacker was able to hide the iPhone Facebook application and install a malicious copy in

What if hackers could take an existing legitimate app or update with a valid digital signature, and modify it in order to use it as a malicious Trojan to access everything on your Android phone or tablet? Last week, researchers from Bluebox Security announced that the Android operating system has been vulnerable to hackers for the past four years, allowing them to modify or manipulate any legitimate application and enabling them to transform it into a Trojan programme. The bug hasn't, so far, been spotted being exploited in the wild, but technical details and a proof-of-concept exploit have been published for a recently announced publicly by Pau Oliva Fora, a mobile security engineer at security firm ViaForensics. Jeff Forristal of Bluebox security stated that the security hole as been around since at least Android 1.6, and it could affect all Android devices i.e. around 900 million devices could be affected by hackers. CyanogenMod , a popular open source d

A recently discovered piece of malware called KRBanker (Korea + Banker = KRBanker) , targeting mostly online end-users at Korean financial institutions. According to nProtect , now an invasive banking Trojan, the new and improved  KRBanker  can block anti-virus software, security websites and even other malware in its quest to steal user information and share it with hackers. Then the malware pings back to the command and control (C&C) server with infection status and then the malware proceeds to download encrypted files on the victim's PC. In the latest variant of the KRBanker malware, scans the PC for lists of DLLs that are related to Korean financial institutions, security software and patches any opcode instructions.  Malware instructed to insert the malicious code that will search and collect any information related to password, account details, and transaction history. Once logged, the compiled information is then sent to a remote server.  KRBanker

Recently we published an article on the attacks against Japanese banks using a new variant of the popular Zeus , one of the most prolific malware of recent history, security experts in fact have detected various versions of the popular malicious code that hit also mobile and social networking platforms . Due its flexibility the malware has been re-engineered several times by cyber criminals that adapted its structure to specific purposes and context, leaving unchanged its core capabilities of stealing banking credentials of victims. Zeus has been a huge success in the criminal circles especially for the sales model, as malware as service, implemented by its authors on many underground sites, let's remind for example the Citadel Trojan one of the most popular on the crimeware market. Fortunately its author, known as Aquabox , has been banned from a large online forum that sells malware and other services to cyber criminals, but many security firms consider Citadel Trojan still very

Malwares are getting updated during the age of social networking. FortiGuard Labs researchers have discovered a new malware called ' Rodpicom Botnet ' that spreads via messaging applications such as Skype and MSN Messenger. Dubbed W32/Rodpicom.A - Rodpicom Botnet sends a message to the victim with a link to a malicious site that leads to downloadable content. When the user clicks the link, the attack downloads another strain of malware, known as Dorkbot . Once the target machine is infected, it checks to see if the victim is using any messaging applications such as Skype or MSN Messenger.  It is revealed that, the malware employs new stealth tactics, including an exception handling technique that generates its own error to dodge analysis and relies on an anti-emulator that attacks the heuristic-scanning capabilities in antivirus software and enables its code to jump around several hundred times. The malware is enough smart to checks the language of the installed operating
