Updated: Since the below-reported vulnerability is highly critical and it would take a few weeks for sysadmins to protect their enterprise network, the research team has not yet disclosed the technical details of the vulnerability. Meanwhile, I have talked with Maksim Malyutin, a member of Embedi research team who discovered the vulnerability in March, and updated my article based on the information provided by him. A critical vulnerability has been discovered in the remote management features on computers shipped with Intel processors for past seven years (and not decade), which could allow attackers to take control of the computers remotely, affecting all Intel systems, including PC, laptops, and servers, with AMT feature enabled. As reported earlier, this critical flaw (CVE-2017-5689) is not a remote code execution, rather Malyutin confirmed to The Hacker News that it's a logical vulnerability that also gives remote attackers an opportunity to exploit this bug using add

It's more than two and half years since the discovery of the critical OpenSSL Heartbleed vulnerability , but the flaw is still alive as it appears that many organizations did not remediate properly to the serious security glitch. It was one of the biggest flaws in the Internet's history that affected the core security of as many as two-thirds of the world's servers i.e. half a million servers at the time of its discovery in April 2014. However, the critical bug still affects more than 199,500 systems even after 2 years and 9 months have already passed, according to a new report published today on Shodan, a search engine that scans for vulnerable devices. Over 199,500 Systems Still Vulnerable to Heartbleed Heartbleed (CVE-2014-0160) was a serious bug in the OpenSSL's implementation of the TLS/DTLS heartbeat extension that allowed attackers to read portions of the affected server's memory, potentially revealing users data that the server isn't intended to re

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

The company that sells digital forensics and mobile hacking tools to others has itself been hacked. Israeli firm Cellebrite , the popular company that provides digital forensics tools and software to help law enforcement access mobile phones in investigations, has had 900 GB of its data stolen by an unknown hacker. But the hacker has not yet publicly released anything from the stolen data archive, which includes its customer information, user databases, and a massive amount of technical data regarding its hacking tools and products. Instead, attackers are looking for possible opportunities to sell the access to Cellebrite system and data on a few selected IRC chat rooms, the hacker told Joseph Cox, contributor at Motherboard , who was contacted by the hacker and received a copy of the stolen data. Meanwhile, Cellebrite also admitted that it recently experienced "unauthorized access to an external web server," and said that it is "conducting an investigation

Nearly two years back, we warned users about publicly accessible MongoDB instances – almost 600 Terabytes (TB) – over the Internet which require no authentication, potentially leaving websites and servers at risk of hacking. These MongoDB instances weren't exposed due to any flaw in its software, but due to a misconfiguration (bad security practice) that let any remote attacker access MongoDB databases without using any special hacking tool. MongoDB later resolved the issue in the next version of its software by setting unrestricted remote access by default in the configuration, thousands of site administrators have not updated their servers yet. But trust me, they'll now regret this! A Hacker is now hijacking and wiping out unsecured MongoDB databases , but keeping a copy of those databases for asking administrators a ransom of 0.2 Bitcoins (nearly US$211) to return the lost data. So, admins without backups are left in a bind. In fact, the rising price of Bitcoin

A 5-year-old serious privilege-escalation vulnerability has been discovered in Linux kernel that affects almost every distro of the Linux operating system, including Redhat, and Ubuntu. Over a month back, a nine-year-old privilege-escalation vulnerability, dubbed " Dirty COW ," was discovered in the Linux kernel that affected every distro of the open-source operating system, including Red Hat, Debian, and Ubuntu. Now, another Linux kernel vulnerability ( CVE-2016-8655 ) that dates back to 2011 disclosed today could allow an unprivileged local user to gain root privileges by exploiting a race condition in the af_packet implementation in the Linux kernel. Philip Pettersson, the researcher who discovered the flaw, was able to create an exploit to gain a root shell on an Ubuntu 16.04 LTS system (Linux Kernel 4.4) and also defeated SMEP/SMAP (Supervisor Mode Execution Prevention/Supervisor Mode Access Prevention) protection to gain kernel code execution abilities. In

Over a month ago we reported about two critical zero-day vulnerabilities in the world's 2nd most popular database management software MySQL: MySQL Remote Root Code Execution (CVE-2016-6662) Privilege Escalation (CVE-2016-6663) At that time, Polish security researcher Dawid Golunski of Legal Hackers who discovered these vulnerabilities published technical details and proof-of-concept exploit code for the first bug only and promised to release details of the second bug (CVE-2016-6663) later. On Tuesday, Golunski has released proof-of-concept (POC) exploits for two vulnerabilities: One is the previously promised critical privilege escalation vulnerability ( CVE-2016-6663 ), and another is a new root privilege escalation bug ( CVE-2016-6664 ) that could allow an attacker to take full control over the database. Both the vulnerabilities affect MySQL version 5.5.51 and earlier, MySQL version 5.6.32 and earlier, and MySQL version 5.7.14 and earlier, as well as MySQL forks

There is no doubt that data breaches are on the rise. Hardly a day goes without headlines about any significant data breach. According to the latest ' Cyber Security Breaches Survey 2016 ' report published by UK government, two-thirds of the biggest firm in the UK have experienced at least a cyber attacks or data breaches within the past 12 months. Here's today, I am writing about top 4 data breaches reported in last 24 hours, threatened your data privacy and online security. 1. Kiddicare Hacked! 794,000 Accounts Leaked Kiddicare has admitted that the company has suffered a data breach, which led to the theft of sensitive data belonging to 794,000 users, including phone numbers and residential addresses. Kiddicare, company that sells child toys and accessories across the United Kingdom, became aware of the data breach after its customers started receiving suspicious text messages – most likely part of a phishing campaign – that attempted to pilfer them to click on a li

Ever wonder how to hack Instagram or how to hack a facebook account? Well, someone just did it! But, remember, even responsibly reporting a security vulnerability could end up in taking legal actions against you. An independent security researcher claims he was threatened by Facebook after he responsibly revealed a series of security vulnerabilities and configuration flaws that allowed him to successfully gained access to sensitive data stored on Instagram servers , including: Source Code of Instagram website SSL Certificates and Private Keys for Instagram Keys used to sign authentication cookies Personal details of Instagram Users and Employees Email server credentials Keys for over a half-dozen critical other functions However, instead of paying him a reward, Facebook has threatened to sue the researcher of intentionally withholding flaws and information from its team. Wesley Weinberg , a senior security researcher at Synack, participated in Facebook's b

Thousands of computers and web servers running Linux and FreeBSD operating systems have been infected over past five years with sophisticated malware that turn the machines into spambots. The new Linux malware, discovered by the security researchers from the antivirus provider Eset, has been dubbed " Mumblehard " because it is Muttering spam from your servers , says Eset 23-page long report (PDF) titled "Unboxing Linux/Mumblehard." Researchers have logged more than 8,500 unique IP addresses during the seven months period of research that were hit by Mumblehard Linux malware and found over 3,000 machines joined them in the past three weeks. Mumblehard features two basic components: Backdoor  Spamming daemon  Both written in the Perl programming language and "feature the same custom packer written in assembly language." The backdoor allows hackers to infiltrate into the system and control the command and control servers, and t

A Flaw has been discovered in the motherboards manufactured by the server manufacturer Supermicro, has left more than 30,000 servers vulnerable to hackers that could allow them to remotely compromise the management interface of unpatched servers. The vulnerability actually resides in the Baseboard Management Controller (BMC) in the WPCM450 line of chips incorporated into the motherboards. Security Researcher at CARInet Security Incident Response Team, discovered that Baseboard Management Controller (BMC) of Supermicro motherboards contain a binary file that stores remote login passwords in clear text and the file is available for download simply by connecting to the specific port, 49152. Baseboard Management Controller (BMC) is the central part of the microcontroller that resides on server motherboard or in the chassis of a blade server or telecom platform. The BMC links to a main processor and other onboard elements via a simple serial bus. Baseboard management contr

It's not been more than 36 hours since eBay revealed it was hacked and we just come to know about three more critical vulnerabilities in eBay website that could allow an attacker to compromise users' account once again, even if you have already reset your account password after the last announcement. Yesterday eBay admitted to the massive data breach that affected 145 million registered users worldwide after its database was compromised. eBay urged its 145 million users to change their passwords after the cyber attack, but are passwords enough? eBay Data breach happened mainly because of their vulnerable infrastructure, not weak passwords. I think eBay's morning just going to be bad to worse as today, three Security researchers came forward with three more different types of critical flaws in eBay website that leave its 145 million users vulnerable to hackers. HACKER UPLOADED SHELL ON eBAY SERVER (UNPATCHED) A critical security flaw in the eBay website for i

The DDoS techniques have massively increased with the attackers becoming more skillful at working around the network security. A massive 300Gbps DDoS attack launched against Spamhaus website almost broke the Internet a year ago and also earlier this year, hackers have succeeded in reaching new heights of the massive DDoS attack targeting content-delivery and anti-DDoS protection firm CloudFlare, reaching more than 400Gbps at its peak of traffic. Akamai's Prolexic Security Engineering and Response Team (PLXsert) issued a threat advisory on Thursday reporting a significant surge in DDoS attacks last month abusing the Simple Network Management Protocol (SNMP) interface in network devices. Simple Network Management Protocol (SNMP) is a UDP-based protocol which is commonly known and often used to manage network devices. SNMP is typically used in devices such as printers, routers and firewalls that can be found in the home and enterprise environments as well. Just as D

In late 2013, Security Researchers identified thousands of Linux systems around the world infected with the OpenSSH b ackdoor trojan and  credential stealer  named Linux/Ebury ,  that allows  unauthorized access of an affected computer to the remote attackers. Antivirus Firm ESET's Reseacher team has been tracking and  investigating the operation behind Linux/Ebury and today team  uncovers the details [ Report PDF ] of a massive,  sophisticated and organized  malware campaign called ' Operation Windigo ', infected more than 500,000 computers and 25,000 dedicated servers. ' We discovered an infrastructure used for malicious activities that is all hosted on compromised servers. We were also able to find a link between different malware components such as Linux/Cdorked, Perl/Calfbot and Win32/Glupteba.M and realized they are all operated by the same group. '  ESET reported. Malware used in Operation Windigo: Linux/Ebury –  an OpenSSH backdoor use

Cryptographer Professor Jean-Jacques Quisquater has become the part of a targeted attack by the US National Security Agency (NSA) and its British counterpart GCHQ, first reported on Saturday morning by De Standaard . A few months back in September 2013 it was revealed that, Belgacom , the largest telecommunications company in Belgium was hacked and number of employees on Belgacom's network, including their servers were compromised. Later in November 2013 , it was revealed that the NSA and GCHQ were behind the infiltration of the company's computers, according to the document provided by the former NSA contractor Edward Snowden . The document detailed that the British intelligence agency GCHQ created fake ' LinkedIn ' and ' Slashdot ' pages to spy on computers of Belgacom network engineers. They used a method called " quantum insert ", to redirect employees to fake websites that contained malware using Man in the middle attack to a spoofed server ( codenamed "

Facebook has paid out its largest Bug Bounty ever of $33,500 to a Brazilian security researcher for discovering and reporting a critical Remote code execution vulnerability, which potentially allows the full control of a server. In September, ' Reginaldo Silva' found an XML External Entity Expansion vulnerability affecting the part of Drupal that handled OpenID, which allows attacker to read any files on the webserver. As a feature, Facebook allows users to access their accounts using OpenID in which it receives an XML document from 3rd service and parse it to verify that it is indeed the correct provider or not i.e. Receives at https://www.facebook.com/openid/receiver.php  In November 2013, while testing Facebook's ' Forgot your password ' functionality, he found that the OpenID process could be manipulated to execute any command on the Facebook server remotely and also allows to read arbitrary files on the webserver. In a Proof-of-Concept ,

In 2013, we have seen a significant increase in the use of a specific distributed denial of service (DDoS) methodology known as Distributed Reflection Denial of Service attacks (DrDoS). Open and misconfigured DNS (Domain Name System) can be used by anyone to resolve domain names to IP addresses are increasingly abused to launch powerful DDoS attacks. But not only the DNS servers, Security Researchers at Symantec  have spotted Network Time Protocol (NTP) reflection DDoS attacks being launched by cyber criminals during the Christmas Holidays. ' Network Time Protocol (NTP) ' is a distributed network clock time synchronization protocol that is used to synchronize computer clock times in a network of computers and runs over port 123 UDP. NTP is one of those set-it-and-forget-it protocols that is configured once and most network administrators don't worry about it after that. Unfortunately, that means it is also not a service that is upgraded often, leaving it vulnerable to th
