High-Severity OpenSSL Vulnerability allows Hackers to Decrypt HTTPS Traffic

High-Severity OpenSSL Vulnerability allows Hackers to Decrypt HTTPS Traffic

May 05, 2016Mohit Kumar
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

Emergency Patch released for Latest Flash Zero-Day Vulnerability

October 17, 2015Khyati Jain
Two days ago, The Hacker News (THN) reported about the Zero-day vulnerability in the freshly patched Adobe Flash Player . The vulnerability was exploited in the wild by a well-known group of Russian hackers, named " Pawn Storm ," to target several foreign affairs ministries worldwide. The zero-day flaw allowed hackers to have complete control of the users' machine, potentially putting all the Flash Player users at a potentially high risk. Since then, there was no patch available to make flawed utility safe. However, Adobe has now patched the zero-day vulnerability, along with some critical vulnerabilities whose details are yet to be disclosed. Yesterday, the company published a post on their official security bulletin ( APSB15-27 ) detailing the risks associated with the zero-day and how a user can get rid of them. The critical vulnerabilities are assigned following CVE numbers: CVE-2015-7645 CVE-2015-7647 CVE-2015-7648 Also, Adobe is kn

Microsoft Ends Windows 7 Mainstream Support

Microsoft Ends Windows 7 Mainstream Support

January 16, 2015Wang Wei
On January 13, 2015, Microsoft's mainstream support for Windows 7 Service Pack (SP) 1 ended, which means the end of free Windows 7's " mainstream support " period, with the operating system now entering "extended support." Many people are still running the aging Windows XP as well as Windows 7. Microsoft already ended its support for Windows XP officially about a year ago on April 8, 2014, and now the company found Windows 7 an old and cranky OS. END OF MAINSTREAM SUPPORT FOR WINDOWS 7 BUT NO WORRIES UNTIL 2020 However, it doesn't mean that the tech giant is going to automatically stop or break your operating system, but it does mean that the company will no longer offer free help and support in case you have any problem with your Windows 7 software. No new features will be added either. Windows 7 is still supported by the company and will continue to receive security updates for at least another five years, i.e. until Jan. 14, 2020. By

First Time Ever Apple Automatically Pushes Security Patch for Mac OS

December 24, 2014Mohit Kumar
First time ever in the History, Apple Inc. has pushed out an automatic security update for Macintosh OS X computers to address a critical security issue that, according to the company, was too risky to wait for users to patch after seeking their prior approval. Despite having the ability for years to silently and automatically update its users computers, Apple typically asks its users' permission to approve them manually or automatically before installing any security update of this kind. But, the company has exercised its ability for the very first time to patch a critical security flaw in a component of its OS X operating system called the Network Time Protocol (NTP) . This newly discovered security vulnerability, assigned CVE-2014-9295, became public late last week and affects all operating systems, including OS X and other Linux and Unix distributions, running versions of NTP4 prior to 4.2.8. NTP is used for synchronizing clocks between computer systems and across the globa

November 18, 2014Swati Khandelwal
Microsoft today released an " out-of-band " security updates to fix a critical vulnerability in all supported versions of its Windows Server software that cyber criminals are exploiting to compromise whole networks of computers. The Emergency patch release comes just one week after Microsoft provided its monthly security patch updates. The November 2014 Patch Tuesday updates included 16 security patches, five of which were rated by Redmond as "critical." The security update (MS14-068) addresses a vulnerability in the Windows component called Microsoft Windows Kerberos KBC , authentication system used by default in the operating system. The flaw allows an attacker to elevate domain user account privileges and access rights to that of a domain administrator account. As a result, if users unknowingly or accidentally run a malicious software on their system, it could therefore be used to compromise the entire network, which could be more dangerous for those who

Thousands of High-Risk Vulnerabilities Found in NOAA Satellite System

September 10, 2014Swati Khandelwal
The informational systems that the National Oceanic and Atmospheric Administration (NOAA) run are loaded with several critical vulnerabilities that could leave it vulnerable to cyber attacks. According to the findings of an audit recently conducted by the Department of Commerce's Office of the Inspector General (OIG), the Joint Polar Satellite System's (JPSS) ground system is vulnerable to a large number of high-risk vulnerabilities. The JPSS ground system is used to collect data from several polar-orbiting weather satellites, and distribute the information to users worldwide. This system also provides command, control and data processing for current and future weather satellites. But, the vulnerabilities identified in the system could impair technology controlling the United States' next generation of polar-orbiting environmental satellites. " Our analysis of the JPSS program's assessments of system vulnerabilities found that, since FY 2012, the number of high-ris
