A critical vulnerability has been discovered in Systemd , the popular init system and service manager for Linux operating systems, that could allow remote attackers to potentially trigger a buffer overflow to execute malicious code on the targeted machines via a DNS response. The vulnerability, designated as CVE-2017-9445 , actually resides in the ' dns_packet_new ' function of 'systemd-resolved,' a DNS response handler component that provides network name resolution to local applications. According to an advisory published Tuesday, a specially crafted malicious DNS response can crash 'systemd-resolved' program remotely when the system tries to lookup for a hostname on an attacker-controlled DNS service. Eventually, large DNS response overflows the buffer, allowing an attacker to overwrite the memory which leads to remote code execution. This means the attackers can remotely run any malware on the targeted system or server via their evil DNS service

What if I say the Tuesday's devastating global malware outbreak was not due to any ransomware infection? Yes, the Petya ransomware attacks that began infecting computers in several countries, including Russia, Ukraine, France, India and the United States on Tuesday and demands $300 ransom was not designed with the intention of restoring the computers at all. According to a new analysis, the virus was designed to look like ransomware but was wiper malware that wipes computers outright, destroying all records from the targeted systems. Comae Technologies Founder Matt Suiche, who closely looked the operation of the malware, said after analyzing the virus, known as Petya, his team found that it was a " Wiper malware ," not ransomware. Security experts even believe the real attack has been disguised to divert world's attention from a state-sponsored attack on Ukraine to a malware outbreak. "We believe the ransomware was, in fact, a lure to control the

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1. Know Thy Endpoints: Identifying and Understanding Your Entry Points Understanding your network's

Microsoft is making every effort to make its Windows operating system more secure and advanced than ever before by beefing up its security practices and hardening it against hackers and cyber attacks in its next release. With the launch of its Windows 10 Creator Update (also known as RedStone 3), which is expected to release sometime between September and October 2017, Microsoft is planning to release lots of security features in an effort to prevent major global malware crisis. Just a few days ago, we reported about Microsoft's plan to build its EMET or Enhanced Mitigation Experience Toolkit into the kernel of the upcoming Windows 10 to boost the security of your computer against complex threats such as zero-day vulnerabilities. Also, the tech giant has planned to remove the SMBv1 (Server Message Block version 1) — a 30-year-old file sharing protocol which came to light last month after the devastating WannaCry outbreak — from the upcoming Windows 10 (1709) Redstone 3

WikiLeaks has just published a new batch of the ongoing Vault 7 leak , and this time the whistleblowing website has unveiled a classified malware for that tracks geo-location of targeted PCs and laptops running the Microsoft Windows operating system. In short, the malware does it by capturing the IDs of nearby public hotspots and then matching them with the global database of public Wi-Fi hotspots' locations. Dubbed ELSA , the alleged CIA's project consists of two main elements: the processing component (Operator Terminal) and the implant (Windows Target) which is typically being deployed on a target Windows host. Here's How the CIA's ELSA Malware Works The Elsa system first installs the malware on a targeted WiFi-enabled machine using separate CIA exploits to gain persistent access on the device. The malware then uses Wi-Fi hardware of the infected computer to scan nearby visible WiFi access points (AP) and records their ESSID – stands for Extended Service Se

The Shadow Brokers , a notorious hacking group that leaked US cyberweapons — which were also abused by the recent ransomware disasters WannaCry and Petya or NotPetya — has now threatened to unmask the identity of a former hacker who worked for the NSA. Besides this, the Shadow Brokers group has also doubled the price for its monthly subscription model of NSA's built hacking tools and zero-day exploits from 100 ZEC (Zcash) to 200 ZEC, which is around $64,400 USD. Moreover, the hacking group has also announced a VIP service for people, who will be entertained by the group for their queries on the leaked hacking tools and exploits. To subscribe to the VIP service, one has to make a one-time payment of 400 ZEC (around US$128,800). Last month, the Shadow Brokers announced to release more zero-days exploits and hacking tools  developed by the US spy agency every month from June 2017, but only to private members who will subscribe for receiving exclusive access to the futur
