A proof-of-concept (PoC) exploit for a critical vulnerability in the Network Time Protocol daemon (ntpd) has been publically released that could allow anyone to crash a server with just a single maliciously crafted packet. The vulnerability has been patched by the Network Time Foundation with the release of NTP 4.2.8p9, which includes a total of 40 security patches, bug fixes, and improvements. The NTP daemon is used in almost every device that needs to synchronize time on computer clocks. NTP got the most attention in late 2014 and 2015 when hackers used it to launch highly amplified DDoS attacks against services. The flaw which affects NTP.org's nptd versions prior to 4.2.8p9, but not including ntp-4.3.94, has been discovered by security researcher Magnus Stubman, who privately disclosed it to the Network Time Foundation on June 24. A patch for the vulnerability was developed and sent to Stubman on 29th September and just two days later, the researcher acknowledged t

Yes, you only need a single laptop with a decent internet connection, rather a massive botnet, to launch overwhelming denial of service (DoS) attacks in order to bring down major Internet servers and modern-day firewalls. Researchers at TDC Security Operations Center have discovered a new attack technique that lone attackers with limited resources (in this case, a laptop and at least 15Mbps of bandwidth) can use to knock large servers offline. Dubbed a BlackNurse attack or the low-rate " Ping of Death " attack, the technique can be used to launch several low-volume DoS attacks by sending specially formed Internet Control Message Protocol (ICMP) packets, or 'pings' that overwhelm the processors on server protected by firewalls from Cisco, Palo Alto Networks, among others. ICMP is a protocol used by routers and other networking devices to send and receive error messages. According to a technical report [ PDF ] published this week, the BlackNurse attack is mo

Imagine a world where the software that powers your favorite apps, secures your online transactions, and keeps your digital life could be outsmarted and taken over by a cleverly disguised piece of code. This isn't a plot from the latest cyber-thriller; it's actually been a reality for years now. How this will change – in a positive or negative direction – as artificial intelligence (AI) takes on a larger role in software development is one of the big uncertainties related to this brave new world. In an era where AI promises to revolutionize how we live and work, the conversation about its security implications cannot be sidelined. As we increasingly rely on AI for tasks ranging from mundane to mission-critical, the question is no longer just, "Can AI  boost cybersecurity ?" (sure!), but also "Can AI  be hacked? " (yes!), "Can one use AI  to hack? " (of course!), and "Will AI  produce secure software ?" (well…). This thought leadership article is about the latter. Cydrill  (a

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

If you think that the HTTP/2 protocol is more secure than the standard HTTP ( Hypertext Transfer Protocol ), then you might be wrong, as it took researchers just four months to discover four flaws in the HTTP/2 protocol. HTTP/2 was launched properly just in May last year after Google bundled its SPDY project into HTTP/2 in February in an effort to speed up the loading of web pages as well as the browsing experience of the online users. Now, security researchers from data center security vendor Imperva today at Black Hat conference revealed details on at least four high-profile vulnerabilities in HTTP/2 – a major revision of the HTTP network protocol that the today's web is based on. The vulnerabilities allow attackers to slow web servers by flooding them with innocent looking messages that carry a payload of gigabytes of data, putting the servers into infinite loops and even causing them to crash. The HTTP/2 protocol can be divided into three layers: The transmissio

OpenSSL has released a series of patches against six vulnerabilities, including a pair of high-severity flaws that could allow attackers to execute malicious code on a web server as well as decrypt HTTPS traffic . OpenSSL is an open-source cryptographic library that is the most widely being used by a significant portion of the Internet services; to cryptographically protect their sensitive Web and e-mail traffic using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol. One of the high-severity flaws, CVE-2016-2107 , allows a man-in-the-middle attacker to initiate a " Padding Oracle Attack " that can decrypt HTTPS traffic if the connection uses AES-CBC cipher and the server supports AES-NI. A Padding Oracle flaw weakens the encryption protection by allowing attackers to repeatedly request plaintext data about an encrypted payload content. The Padding Oracle flaw ( exploit code ) was discovered by Juraj Somorovsky using his own developed tool c

How to Hack Facebook? That's the most commonly asked question during this decade. It's a hacker dream to hack Facebook website for earning bug bounty or for any malicious purpose. Facebook security team recently found that someone, probably a blackhat hacker with malicious intent, has breached into its server and installed a backdoor that was configured to steal Facebook employees' login credentials. Since the backdoor discovered in the Facebook's corporate server, not on its main server, Facebook user accounts are not affected by this incident. Though the company would have never known about the backdoor if a whitehat hacker had never spotted the backdoor script while hunting for vulnerabilities. Also Read: Ever Wondered How Facebook Decides, How much Bounty Should be Paid? Security researcher Orange Tsai of Taiwanese security vendor DEVCORE accidentally came across a backdoor script on one of Facebook's corporate servers while finding bugs to earn cash reward fr

Utah State computer systems are experiencing a massive cyber attack on up to 300 Million Hacking attempts per day due to National Security Agency's (NSA) data center in the state. Yes, 300,000,000 hacking attempts in a day! According to the statistical survey, it is evident that the computer systems in the US State of Utah began to experience the hacking attack a few years back, precisely, soon after the NSA revelations by global surveillance whistleblower Edward Snowden. It is a less-known fact that the NSA has built its new data center near the city of Bluffdale, Utah. However, a couple of years back, when Snowden revealed the presence of the data center, the attacks have constantly been going on. The PRISM spying program by Big Brothers at NSA might have shifted the attention of hackers for the retaliation against mass-surveillance and flared up this heightened cyber attacks against the spying agency. According to Utah Commissioner of public safety, Keith S

A 'Serious' security vulnerability has been discovered and fixed in OpenSSH – one of the most widely used open-source implementations of the Secure Shell (SSH) Protocol. The critical vulnerability could be exploited by hackers to force clients to leak their secret private cryptographic keys, potentially exposing users to Man-in-the-Middle (MITM) attacks. What Causes the Flaw to occur? The serious bug was actually the result of a code that enables an experimental " roaming " feature in the OpenSSH versions 5.4 to 7.1 in order to let users resume connections. However, The roaming feature contains two different vulnerabilities: An information sharing flaw ( CVE-2016-0777 ) A less harmless buffer overflow flaw ( CVE-2016-0778 ) The vulnerability does not have any catchy name like some previous OpenSSH flaws. Impact of the Vulnerability This new feature can be exploited by hackers, who could use a malicious OpenSSH server to trick a

Juniper Networks has announced that it has discovered " unauthorized code " in ScreenOS , the operating system for its NetScreen firewalls, that could allow an attacker to decrypt traffic sent through Virtual Private Networks (VPNs). It's not clear what caused the code to get there or how long it has been there, but the release notes posted by Juniper suggest the earliest buggy versions of the software date back to at least 2012 and possibly earlier. The backdoor impacts NetScreen firewalls using ScreenOS 6.2.0r15 through 6.2.0r18 and 6.3.0r12 through 6.3.0r20, states the advisory published by the company. However, there's no evidence right now that whether the backdoor was present in other Juniper OSes or devices. The issue was uncovered during an internal code review of the software, according to Juniper chief information officer Bob Worrall , and requires immediate patching by upgrading to a new version of the software just released today. &quo

The bad news is that internal data breaches are on the rise. And one of the biggest culprits? USB devices. In the past few years, there has been many organizations tracking down the loss of sensitive/confidential information due to the usage of USB drives and other mass storage media. Cyber-security breaches and data theft are making more and more IT leaders paranoid about security than ever before. Why are USB devices dangerous? USB devices can hold a lot of information. For example, a 128 GB USB flash drive can store 60,000 photos, 20,000 songs, 100+ videos, and more. Just imagine how many protected corporate files could fit on one drive. Also, the storage capacity of USB devices is only going to increase. USB devices are super portable. Some USB storage devices are the size of a small coin. This makes them very difficult to visually detect when plugged into an open port. USB devices are cheap and easy to find. If you're in the market for a USB storage device, there

A wave of excitement in The Pirate Bay lovers. After almost two months of untimely and unexpected outage, the infamous torrent-indexing website The Pirate Bay (TPB) made a defiant return on Saturday. The Pirate Bay — a widely popular file-sharing website predominantly used to share copyrighted material free of charge — went dark from the Internet following a raid in Sweden late last year. In response to a complaint from Swedish anti-piracy group Rights Alliance, the police raided The Pirate Bay's server room in Stockholm and seized several servers and other equipment. Though, its almost impossible to keep The Pirate Bay offline for too long, last took down was the longest outage the torrenting site has ever experienced. The site is back one day early based on the countdown timer that was running on the official domain of TPB, i.e. thepiratebay.se . Anyone visiting thepiratebay.se domain today will be welcomed with a functioning site. People are already uploading and downloa

Google introduced a new security tool to help developers detect bugs and security glitches in the network traffic security that may leave passwords and other sensitive information open to snooping. The open source tool, dubbed as Nogotofail , has been launched by the technology giant in sake of a number of vulnerabilities discovered in the implementation of the transport layer security, from the most critical Heartbleed bug in OpenSSL to the Apple's gotofail bug to the recent POODLE bug in SSL version 3. The company has made the Nogotofail tool available on GitHub, so that so anyone can test their applications, contribute new features to the project, provide support for more platforms, and help improve the security of the internet. Android security engineer Chad Brubaker said that the Nogotofail main purpose is to confirm that internet-connected devices and applications aren't vulnerable to transport layer security (TLS) and Secure Sockets Layer (SSL) encry

Till now, he have heard about " Bitcoin digital wallet hacked " or " Bitcoin website hacked ", but now a hacker has stolen cryptocurrency from mining pools and generated $83,000 in digital cash in more than four months by gaining access to a Canadian Internet provider. Bitcoin is a virtual currency that makes use of cryptography to create and transfer bitcoins. Users make use of digital wallets to store bitcoin addresses from which bitcoins are received or sent. Bitcoin uses public-key cryptography so that each address is associated with a pair of mathematically linked public and private keys that are held in the wallet. Researchers at Dell SecureWorks Counter Threat Unit (CTU) , a cyber intelligence company, have discovered a series of malicious activities in which a cryptocurrency thief used bogus Border Gateway Protocol ( BGP ) broadcasts to hijack networks belonging to no less than 19 Internet service providers, including Amazon and other hosting services like DigitalO

Security expert Ebrahim Hegazy has found a Password disclosure vulnerability in Barracuda update servers which allows to gain access to employee credentials. The Egyptian information security advisor Ebrahim Hegazy( @Zigoo0 ) has found a Password disclosure vulnerability in one of Barracuda update servers which allows the attackers to gain access to all its employee data. When the system administrator needs to protect a directory with a second authentication layer (basic authentication ) besides the back-end authentication, he can do it with multiple methods, one of that methods is through the configuration of .htaccess and .htpasswd files. A proper configuration could prevent a visitor to surf reserved area (e.g /Cpanel or /admin), in this scenario a popup proposes to the user asking to enter authentication credentials, that credentials are saved inside .htpasswd file as: Username:Password In normal scenarios the .htpasswd file should be stored outside the we

Microsoft next updates are fully loaded with 57 different security vulnerabilities through 12 separate updates. It will roll out fixes as it always does on Patch Tuesday, the second Tuesday of every month. Anyone who uses Windows as their primary operating system will be quite familiar with Patch Tuesday. According to Microsoft's advisory , The 12 security update including two for Internet Explorer (IE), that will patch a near-record 57 vulnerabilities in the browser, Windows, Office and the enterprise-critical Exchange Server email software. Part of this update will be security patches for every single version of Internet Explorer. Apparently, this is to address a security hole that leaves users open to being exploited through drive-by attacks. Out of the 12 updates, five are considered " critical, " and others are labeled " important, ". As always, the critical patches will automatically install for any Windows users with automatic updates enabled. Two of the
