The digital currency Bitcoin has suffered yet another hack. Bitcoin wallet site Instawallet has been taken offline after a security compromise, has suspended its service indefinitely. Instawallet didn't say in a notice on its website how many bitcoins were stolen after hackers fraudulently accessed company database. " The Instawallet service is suspended indefinitely until we are able to develop an alternative architecture. Our database was fraudulently accessed, due to the very nature of Instawallet it is impossible to reopen the service as-is. " Bitcoin is a virtual currency that uses a peer-to-peer system to confirm transactions through public key cryptography. The company also announced it will accept claims for individual Instawallets for the first 90 days, using the wallets' URL and key to file the claim. Clients will then be refunded the currency value if the balance is less than 50 BTC. The breach follows a series of attacks targeting bitcoin services. In Sep...

In earlier posts, our Facebook hacker ' Nir Goldshlager ' exposed two serious Facebook oAuth Flaws. One, Hacking a Facebook account even without the user installing an application on their account and second, various ways to bypassing the regex protection in Facebook OAuth. This time, Nir illustrated a scenario attack  " what happens when a application is installed on the victim's account and how an attacker can manipulate it so easily " According to hacker, if the victim has an installed application like Skype or Dropbox, still hacker is able to take control over their accounts.  For this, an attacker required only a url redirection or cross site scripting  vulnerability on the Facebook owner app domain i.e in this scenario we are talking about skype facebook app. In many bug bounty programs URL redirection is not considered as an valid vulnerability for reward i.e Google Bug bounty Program. Nir also demonstrated...

J. Taikwok Yung is 33, lives with his mom in Brooklyn, and bought domain names that criticize billionaire Donald Trump and cybersquatting him.  Cybersquatting  is a legitimate crime that's defined by the Anticybersquatting Consumer Protection Act. " Cybersquatting (also known as domain squatting), according to the United States federal law known as the Anticybersquatting Consumer Protection Act, is registering, trafficking in, or using a domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. The cybersquatter then offers to sell the domain to the person or company who owns a trademark contained within the name at an inflated price. " from wikipedia. Donald Trump is seeking $400,000 in damages from a Brooklyn man, who register four domains trumpindia.com, trumpbeijing.com, trumpmumbai.com and trumpabudhabi.com as domain names of well-known trademarks and then try to sell the names back to the trademark owners...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

Spammy Facebook apps are nothing new, the web giant has been dealing with suspicious behavior apps since the website launched the Facebook Platform for developers in 2007. As an open source app development tool, anyone can create an app, including people who really just want to steal your information, and your money. With cyber crime  including identity theft, on the rise, more Facebook users should begin to pay closer attention to what they click on, especially if it is shared in a spammy way. Sophos reports that nearly 60,000 people have clicked on one scam in particular, which is one that promises to allow you to see who has viewed your profile. The app automatically posts a comment to the users timeline, and sometimes posts as a photo with the message ' OMG OMG OMG… I cant believe this actually works! Now you really can see who viewed your profile ! on (link here). ' The app does not actually allow users to see profile views but instead leads them, and anyone...

We are in digital era, everything is connected to the large networks and applications benefit of even more complex devices that deeply interact with owner, in this scenario security requirements assume a crucial importance and security of overall architecture also depend on security of single components. In these months mobile users have gone crazy for a simple video game named Ruzzle , developed by the Swedish gaming company MAG Interactive, available for iOS and Android devices. The game mechanism is inspired by the board games Boggle and Scrabble. Early 2013 the researcher at Hacktive Security started a study on most spread mobile applications such as popular Ruzzle focusing on the protocol implemented and possible repercussion on user's privacy. Ruzzle protocol use Json for response within a user's session, security analyst discovered that is it possible to tamper them due the absence of control on server side on data sent by the application. The leak of data va...

Hacking group Anonymous claims to have broken into North Korean site Uriminzokkiri.com and got their hands on more than 15,000 user credentials. A message posted online makes the claim and includes details for six accounts, apparently showing user names, e-mail addresses, birth dates, and hashed passwords. " Enjoy these few records as a proof of our access to your systems (random innocent citizens, collateral damage, because they were stupid enough to choose idiot passwords), we got all over 15k membership records of www.uriminzokkiri.com and many more. First we gonna wipe your data, then we gonna wipe your badass dictatorship "government" ." Of the six users, three have Korean names and the other three appear to be Chinese. " North Korean government is increasingly becoming a threat to peace and freedom.

Cyber criminals  are using popular note-taking app Evernote as Command-and-Control Server to give commands to the malware installed on infected PCs using botnets. TrendMicro uncovered a malware detected as " BKDR_VERNOT.A " tried to communicate with Command-and-Control Server using Evernote. Malware delivered via an executable file that installs the malware as a dynamic-link library. The installer then ties the DLL into a legitimate running process, hiding it from casual detection. Once installed, BKDR_VERNOT.A can perform several backdoor commands such as downloading, executing, and renaming files. It then gathers information from the infected system, including details about its OS, timezone, user name, computer name, registered owner and organization. Researchers  also pointed out that the backdoor may have also used Evernote as a location to upload stolen data. " Unfortunately, during our testing, it was not able to logi...

The last week has seen probably the largest distributed denial-of-service (DDoS) attack ever. A massive 300Gbps was thrown against Internet blacklist maintainer Spamhaus' website but the anti-spam organisation , CloudFlare was able to recover from the attack and get its core services back up and running.  Spamhaus, a group based in both London and Geneva, is a non-profit organisation that aims to help email providers filter out spam and other unwanted content. Spamhaus is pretty resilient, as its own network is distributed across many countries, but the attack was still enough to knock its site offline on March 18. Five national cyber-police-forces are investigating the attacks.  A group calling itself STOPhaus,  an alliance of hactivists and cyber criminals is believed to responsible for bombarding Spamhaus with up to 300Gbps. The attacks on Spamhaus illustrate a larger problem with the vulnerability of systems fundamental to the architecture of...

Tibetan and Uyghur activists are once again targeted with a new malware, specially designed for Android devices. This is the first documented attack that targets Android smartphones . Security researchers at Kaspersky say they've  found a targeted malware attack on Android phones that seems to come from China. The attack relied heavily on social engineering, a kind of verbal manipulation, to hack into their targets' devices. Malware seeks to steal information like contacts, call logs, and SMS of people who work in the field of human rights. Kaspersky has identified the Trojan as " Chuli ," after a command function that shows up prior to posting stolen data to the command-and-control server at the URL: hxxp://64.78.161.133/*victims's_cell_phone_number*/process.php. On March 24, the attackers infiltrated the email account of a high-profile Tibetan activist, and used that account to send a spear-phishing email to their contacts list. ...

A couple of years ago, the tech world was abuzz about the cloud. Cloud computing refers to computing where the processing or storage takes place on a networked series of computers rather than on the device that you're using. Whether you're using a PC, laptop, tablet, smartphone, television, or video game console, everything now connected to Cloud Storage and always in sync. But there is a limitation, that smartphones can essentially remember deleted information, which poses a huge risk to organizations that issue smartphones to employees and to organizations that don't explicitly disable the use of personal devices for work-related computing. Researchers at the University of Glasgow found that cloud storage apps that say they send files to the cloud also leave retrievable versions of files on the devices. They  tested some cloud-based file storage systems tested included Box, Dropbox and SugarSync on HTC Desire, running Android 2.1, and an iPhone 3S running iOS 3. They...

Oracle has released emergency patches multiple of times in recent months for Java for one after another set of vulnerabilities . About 100 million computers reported to be vulnerable to unauthorized access via different flaw in Java software. Department of Homeland Security's US-CERT already warned users to disable Java permanently to stop hackers from taking control of users' machines. Security experts advised,'T he best defense we have right now for these kinds of attacks is to disable Java in the browser forever' . According to Websense experts, Most browser installations use outdated versions of the Java plug-in that are vulnerable to at least one of several exploits used in popular web attack toolkit. Exploit kits are a very common tool for distribution of many Java-based threats. To detect the vulnerable Java versions that are installed on systems and Websense experts, used their technology via ' threat intelligence network' , which monitors bi...

Canonical, the software company that manages and funds Ubuntu, announced to develop a new, open-source operating system customized especially for Chinese users called ' UbuntuKylin OS '. According to the BBC, Chinese government and Canonical partner to launch its home grown operating system. China signaled its intention to move away from its dependence on western software products i.e windows. Canonical staff and Chinese researchers will be working on the OS at a Beijing lab. China's Ministry of Industry and Information Technology will collaborate with Canonical to come up with Kylin to run on servers, aimed at websites, online shops, and hosting. The first version of Ubuntu Kylin is for the laptops and desktops. Therefore the Android dominates the Chinese market for a few more years.

Apple is beefing up the security of its iCloud and Apple ID accounts by adding two-factor authentication to the account login process. Users who activate the option will be required to enter a four-digit code they may receive via SMS message, aside from the usual password. Two-factor authentication is gaining popularity because it makes login to online services significantly more secure compared to regular process. Apple has rolled out this functionality for Apple ID and iCloud users. " Turning on two-step verification reduces the possibility of someone accessing or making unauthorized changes to your account information at My Apple ID or making purchases using your account ," Apple said . Apple will be using both the app and SMS versions, providing security codes through texts as well as the FindMyiPhone app. As long as users are able to remember their password, they will have the ability to generate a new recovery key from the My Apple ID web...

T-Mobile devices having a default Wi-Fi Calling feature that keeps you connected in areas with little or no coverage using Wi-Fi connection. But according to new finding by students Jethro Beekman and Christopher Thompson from University of California Berkeley, that this feature lets millions of Android users vulnerable to Man-in-the-Middle attack . The simplest way to become a man-in-the-middle would be for the attacker to be on the same open wireless network as the victim, such as at a coffee shop or other public space. In a technical analysis of the exploit, The flaw could potentially allow hackers to access and modify calls and messages made by T-Mobile users on certain Android smartphones. Beekman and Thompson informed T-Mobile, a division of Deutsche Telekom, of the flaw in December and on March 18 T-Mobile was able to resolve the issue for all affected phone models. T-Mobile uses regular VoIP for Wi-Fi Calling instead of a connection that encry...

Yesterday we reported about a massive Cyber attack on South Korea that was responsible for shutting down networks of South Korean banks and TV broadcasters. Police are still investigating the cyber attack  but the country's Communications Commission has revealed that the hacking originated from a Chinese IP address. Symantec Security team analyze the code used in the cyber attacks against South Korea and they discovered an additional component used in this attack that is capable of wiping Linux machines.  The malware, which it called Jokra, contains a module for wiping remote Linux machines. ' The included module checks Windows 7 and Windows XP computers for an application called mRemote, an open source, multi-protocol remote connections manager. ' Symantec said. McAfee also published an analysis of the attack code, which wrote over a computer's master boot record, which is the first sector of the computer's hard drive that the computer checks before ...

The US government is claiming that authorities do not need court warrants to affix GPS devices to vehicles to monitor their every move. t's been more than a year since a Supreme Court decision established that affixing a GPS tracking device to a vehicle constitutes a search under the constitution. The decision, United States vs. Jones , throws out the drug-related conviction of nightclub owner Antoine Jones. The GPS locator was installed the day after the warrant expired and while the vehicle was outside of the department's jurisdiction, and DC police tracked Jones for nearly a month after installation before arresting him. " Requiring a warrant and probable cause before officers may attach a GPS device to a vehicle, which is inherently mobile and may no longer be at the location observed when the warrant is obtained, would seriously impede the government's ability to investigate drug trafficking, terrorism, and other crimes. Law enforcement officers co...

When launched, Trojan.Yontoo.1 displays a dialogue window that asks the user if they want to install Free Twit Tube. after the user presses ' Continue ', instead of the promis...

Computer networks at major South Korean banks and top TV broadcasters crashed simultaneously Wednesday, during a Massive cyber attack. South Korean police investigating reports from several major broadcasters and banks. least three broadcasters KBS, MBC and YTN and the Shinhan and Nonghyu banks reported that their computer networks had been crached. The state-run Korea Information Security Agency said that Screens went blank at 2 p.m. and more than seven hours later some systems were still down.  The take down was apparently not from a distributed denial-of-service (DDOS) attack, but a virus that has apparently infected machines in these organizations and delivered its payload simultaneously. An official at the Korea Communications Commission said investigators speculate that malicious code was spread from company servers that send automatic updates of security software and virus patches. The Associated Press says: " The latest network para...
