WhatsApp is again in news but this time not for any security holes, but for its all new and, of course, much-awaited Free Voice Calling feature — similar to other instant messaging apps like Skype and Viber allow users to make voice calls using Internet. After launching its much-awaited Web client (dubbed WhatsApp Web ) to Android users, the most popular mobile messaging application WhatsApp has started rolling out the promised free voice calling feature, and this time again to Android users first. Late last night, some screenshots of WhatsApp's new voice calling feature appeared on Reddit. Reportedly, this new feature will allow WhatsApp users to make free voice calls to their online pals by simply tapping your phone icon to call their WhatsApp friends. The report broke when a Reddit user ( pradnesh07 ) received a WhatsApp call from a friend, and this is how the feature get activated. The free voice calling feature, for now, seems to be invite-only. So, if you still have to ...

Facebook users just Beware!! Don't click any porn links on Facebook. Foremost reason is that you have thousands of good porn sites out there, but there's an extra good reason right now. Rogue pornography links on the world's most popular social network have reportedly infected over 110,000 Facebook users with a malware Trojan in just two days and it is still on the rise, a security researcher warned Friday. The Facebook malware disguised as a Flash Player update and spreads itself by posting links to a pornographic video from the Facebook accounts of previously infected users. The malware generally tags as many as 20 friends of the infected user . "In the new technique, which we call it ' Magnet ,' the malware gets more visibility to potential victims by tagging the friends of the victim in the malicious post," said Mohammad Faghani, a senior consultant at PricewaterhouseCoopers, in a mailing list post to the Full Disclosure infosec hangout.  "A tag may...

After the disclosure of extremely critical GHOST vulnerability in the GNU C library (glibc) — a widely used component of most Linux distributions, security researchers have discovered that PHP applications, including the WordPress Content Management System (CMS), could also be affected by the bug. " GHOST " is a serious vulnerability ( CVE-2015-0235 ), announced this week by the researchers of California-based security firm Qualys, that involves a heap-based buffer overflow in the glibc function name - "GetHOSTbyname()." Researchers said the vulnerability has been present in the glibc code since 2000. Though the major Linux distributors such as Red Hat , Debian and Ubuntu , have already updated their software against the flaw, GHOST could be used by hackers against only a handful of applications currently to remotely run executable code and silently gain control of a Linux server. As we explained in our previous article, heap-based buffer overflow was found ...

Last week, the most popular mobile messaging application WhatsApp finally arrived on the web — dubbed WhatsApp Web , but unfortunately it needs some improvements in its web version. An independent 17-year-old security researcher Indrajeet Bhuyan reported two security holes in the WhatsApp web client that in some way exposes its users' privacy. Bhuyan called the first hole, WhatsApp photo privacy bug and the other WhatsApp Web Photo Sync Bug. Bhuyan is the same security researcher who reported us the vulnerability in the widely popular mobile messaging app which allowed anyone to remotely crash WhatsApp by sending a specially crafted message of just 2kb in size, resulting in the loss of conversations. Whatsapp Photo Privacy Bug According to him, the new version of WhatsApp Web allows us to view a user's profile image even if we are not on the contact list of that user. Even if the user has set the profile image privacy setting to " Contacts Only ," the pro...

The makers of ultra secure BlackPhone titled by Silent Circle as, " world's first Smartphone which places privacy and control directly in the hands of its users ," have recently fixed a critical vulnerability in the instant messaging application that allows hackers to run malicious code on the handsets. BlackPhone was also hacked last year at the BlackHat security conference , but the interesting factor about the recent hack was that the attackers only needed to send just a message on a targeted phone number in order to compromise the device. The vulnerability was first discovered and disclosed by Mark Dowd , a principal security researcher at the Australia-based consultancy firm Azimuth Security. Dowd discovered the issue late in 2014, but waited to disclose it until Blackphone got their patches and fixes in place. The flaw actually resides in Silent Text application — the secure text messaging application bundled with the BlackPhone handsets, which is al...
