Chinese cybersecurity researchers have uncovered a widespread, ongoing malware campaign that has already hijacked over 100,000 home routers and modified their DNS settings to hack users with malicious web pages—especially if they visit banking sites—and steal their login credentials. Dubbed GhostDNS , the campaign has many similarities with the infamous DNSChanger malware that works by changing DNS server settings on an infected device, allowing attackers to route the users' internet traffic through malicious servers and steal sensitive data. According to a new report from cybersecurity firm Qihoo 360's NetLab, just like the regular DNSChanger campaign, GhostDNS scans for the IP addresses for routers that use weak or no password at all, accesses the routers' settings, and then changes the router's default DNS address to the one controlled by the attackers. GhostDNS System: List of Modules and Sub-Modules The GhostDNS system mainly includes four modules: ...

The desktop version of the security and privacy-focused, end-to-end encrypted messaging app, Telegram , has been found leaking both users' private and public IP addresses by default during voice calls. With 200 million monthly active users as of March 2018, Telegram promotes itself as an ultra-secure instant messaging service that lets its users make end-to-end encrypted chat and voice call with other users over the Internet. Security researcher Dhiraj Mishra uncovered a vulnerability (CVE-2018-17780) in the official Desktop version of Telegram (tdesktop) for Windows, Mac, and Linux, and Telegram Messenger for Windows apps that was leaking users' IP addresses by default during voice calls due to its peer-to-peer (P2P) framework. To improve voice quality, Telegram by default uses a P2P framework for establishing a direct connection between the two users while initiating a voice call, exposing the IP addresses of the two participants. Telegram Calls Could Leak Your ...

Logged out from your Facebook account automatically? Well you're not alone… Facebook just admitted that an unknown hacker or a group of hackers exploited a zero-day vulnerability in its social media platform that allowed them to steal secret access tokens for more than 50 million accounts. UPDATE:  10 Important Updates You Need To Know About the Latest Facebook Hacking Incident . In a brief blog post published Friday, Facebook revealed that its security team discovered the attack three days ago (on 25 September) and they are still investigating the security incident. The vulnerability, whose technical details has yet not been disclosed and now patched by Facebook, resided in the "View As" feature—an option that allows users to find out what other Facebook users would see if they visit your profile. According to the social media giant, the vulnerability allowed hackers to steal secret access tokens that could then be used to directly access users' private in...

Julian Assange, the founder of popular whistleblower website WikiLeaks, is stepping down from the position of editor-in-chief of the organisation under "extraordinary circumstances." Assange, the 47-year-old Australian hacker, founded WikiLeaks in 2006 and has since made many high-profile leaks, exposing 'dirty' secrets of several individuals, political parties as well as government organisations across the world. Assange has been forced to live in the Ecuadorian Embassy in London since June 2012, after he was granted asylum by the Ecuador government when a British court ordered his extradition to Sweden to face questioning sexual assault and rape. Ecuador has cut Assange off the Internet and any communication with the outside world except for his lawyers since late March this year, making it difficult for him to do his job of editor-in-chief to run WikiLeaks. Wikileaks Appoints Its New Editor-in-Chief According to a recent tweet from Wikileaks, those ...

A cybersecurity researcher with Google Project Zero has released the details, and a proof-of-concept (PoC) exploit for a high severity vulnerability that exists in Linux kernel since kernel version 3.16 through 4.18.8. Discovered by white hat hacker Jann Horn, the kernel vulnerability (CVE-2018-17182) is a cache invalidation bug in the Linux memory management subsystem that leads to use-after-free vulnerability, which if exploited, could allow an attacker to gain root privileges on the targeted system. The use-after-free (UAF) vulnerabilities are a class of memory corruption bug that can be exploited by unprivileged users to corrupt or alter data in memory, enabling them to cause a denial of service (system crash) or escalate privileges to gain administrative access on a system. Linux Kernel Exploit Takes an Hour to Gain Root Access However, Horn says his PoC Linux kernel exploit made available to the public "takes about an hour to run before popping a root shell....
