SonicWall Left a VPN Flaw Partially Unpatched Amidst 0-Day Attacks

SonicWall Left a VPN Flaw Partially Unpatched Amidst 0-Day Attacks
June 22, 2021Ravie Lakshmanan
A critical vulnerability in SonicWall VPN appliances that was believed to have been patched last year has been now found to be "botched," with the company leaving a memory leak flaw unaddressed, until now, that could permit a remote attacker to gain access to sensitive information. The shortcoming was rectified in an update rolled out to SonicOS on June 22.  Tracked as  CVE-2021-20019  (CVSS score: 5.3), the vulnerability is the consequence of a memory leak when sending a specially-crafted unauthenticated HTTP request, culminating in information disclosure. It's worth noting that SonicWall's decision to hold back the patch comes amid  multiple   zero-day   disclosures  affecting its remote access VPN and email security products that have been exploited in a series of in-the-wild attacks to deploy backdoors and a new strain of ransomware called FIVEHANDS. Howevere, there is no evidence that the flaw is being exploited in the wild. Memory Dump PoC "SonicWal

December 22, 2017Wang Wei
While continuing its crackdown on services that help Chinese citizens to bypass Great Firewall, Chinese authorities have sentenced a man to five-and-a-half years in prison for selling a VPN service without obtaining a proper license from the government. Earlier this year, the Chinese government announced a ban on "unauthorized" VPN services , making it mandatory for companies to obtain an appropriate license from the government in order to operate in the country. Citizens in China usually make use of VPN and Proxy services to bypass the country's Great Firewall, also known as the Golden Shield project, which employs a variety of tricks to censor the Internet in the country. The Great Firewall project already blocked access to more than 150 out of the world's 1,000 top websites, which includes Google, Facebook, Twitter, Dropbox, Tumblr, and The Pirate Bay in the country.

June 22, 2017Swati Khandelwal
A security researcher has found four vulnerabilities, including a critical remote code execution bug, in OpenVPN, those were not even caught in the two big security audits of the open source VPN software this year. OpenVPN is one of the most popular and widely used open source VPN software solutions mostly used for various connectivity needs, but it is especially popular for anonymous and private access to the Internet. This year, two independent security audits of OpenVPN were carried out to look for flaws, backdoors, and other defects in the open source software – one conducted by a team led by Johns Hopkins University crypto-boffin Dr. Matthew D. Green. The audits resulted in a patch of a few vulnerabilities in the widely used open source software, giving OpenVPN a clean chit. Researcher Used Fuzzer to find Bugs in OpenVPN Researcher Guido Vranken of Netherlands exclusively used a fuzzer and recently discovered four security holes in OpenVPN that escaped both the secur

Use Secure VPNs (Lifetime Subscription) to Prevent ISPs From Spying On You
March 27, 2017The Hacker News
Data Privacy is a serious concern today with the vast availability of personal data over the Internet – a digital universe where websites collect your personal information and sell them to advertisers for dollars, and where hackers can easily steal your data from the ill-equipped. If this wasn't enough, US Senate voted last week to eliminate privacy rules that would have forced ISPs to get your permission before selling your Web browsing history and app usage history to advertisers. If passed, ISPs like Verizon, Comcast, and AT&T, can collect and sell data on what you buy, where you browse, and what you search, to advertisers all without taking your consent in order to earn more bucks. How to Prevent ISPs And Hackers From Spying On You So, how do you keep your data away from advertisers as well as hackers? Private Browsing! If you're worried about identity thieves or ISPs spying on or throttling your traffic, the most efficient way to secure your privacy on the

Today, most of you surf the web unaware of the fact that websites collect your data and track your locations and makes millions by sharing your search histories, location data, and buying habits with advertisers and marketers. And if this isn't enough, there are hackers and cyber criminals out there who have the ability to easily steal your sensitive and personal data from the ill-equipped websites. In short, the bitter truth is that you have no or very little online privacy. To resolve this issue, you need a Virtual Private Network (VPN). If you are worried about online Privacy and have not thought about using a VPN, it might be time to get one. But, the question is: What are the best anonymous VPN services? Unfortunately, not all VPNs are as anonymous as they claim to be. Some VPN services keep extensive logs of their users' browsing activities, including IP-addresses for weeks, which nullify the point of using a VPN for privacy. Want Privacy While You Surf

Juniper Firewalls with ScreenOS Backdoored Since 2012

Juniper Firewalls with ScreenOS Backdoored Since 2012
December 18, 2015Swati Khandelwal
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

Critical 'Port Fail' Vulnerability Reveals Real IP Addresses of VPN Users

Critical 'Port Fail' Vulnerability Reveals Real IP Addresses of VPN Users
November 27, 2015Mohit Kumar
A newly discovered flaw affecting all VPN protocols and operating systems has the capability to reveal the real IP-addresses of users' computers, including BitTorrent users, with relative ease. The vulnerability, dubbed Port Fail by VPN provider Perfect Privacy (PP) who discovered the issue, is a simple port forwarding trick and affects those services that: Allow port forwarding Have no protection against this specific attack Port Forwarding trick means if an attacker uses the same VPN ( Virtual Private Network ) as the victim, then the real IP-address of the victim can be exposed by forwarding Internet traffic to a specific port. "The crucial issue here is that a VPN user connecting to his own VPN server will use his default route with his real IP address, as this is required for the VPN connection to work," Perfect Privacy wrote in a blog post on Thursday.

How NSA successfully Broke Trillions of Encrypted Connections
October 16, 2015Swati Khandelwal
Yes, it seems like the mystery has been solved. We are aware of the United States National Security Agency (NSA) powers to break almost unbreakable encryption used on the Internet and intercept nearly Trillions of Internet connections – thanks to the revelations made by whistleblower Edward Snowden in 2013. However, what we are not aware of is exactly how did the NSA apparently intercept VPN connections, and decrypt SSH and HTTPS, allowing the agency to read hundreds of Millions of personal, private emails from persons around the globe. Also Read:  Top Best Password Managers . Now, computer scientists Alex Halderman and Nadia Heninger have presented a paper at the ACM Conference on Computer and Communications Security that advances the most plausible theory as to how the NSA broke some of the most widespread encryption used on the Internet. According to the paper, the NSA has exploited common implementations of the Diffie-Hellman key exchange algorithm – a common

May 29, 2015Swati Khandelwal
The bandwidth of Millions of users of a popular free VPN service is being sold without their knowledge in an attempt to cover the cost of its free service, which could result in a vast botnet-for-sale network. " Hola ," a free virtual private network, is designed to help people abroad watch region restricted shows like American Netflix, and other streaming United States media. Hola is selling users' bandwidth: Hola is easy-to-use browser plugin available in the Google Chrome Store with currently more than 6 Million downloads . But, unfortunately, Hola could be used by hackers to maliciously attack websites, potentially putting its users at risk of being involved in illegal or abusive activities. Hola uses a peer-to-peer system to route users' traffic. So, if you are in Denmark and wants to watch a show from America, you might be routed through America-based user's Internet connections.

Hacker exploits Heartbleed bug to Hijack VPN Sessions
April 19, 2014Mohit Kumar
Cyber criminals have explored one more way to exploit Heartbleed OpenSSL bug against organisations to hijack multiple active web sessions conducted over a virtual private network connection. The consulting and incident response Mandiant investigated targeted attack against an unnamed organization and said the hackers have exploited the " Heartbleed " security vulnerability in OpenSSL running in the client's SSL VPN concentrator to remotely access active sessions of an organization's internal network. The incident is the result of attacks leveraging the OpenSSL Heartbleed vulnerabilities, which resides in the OpenSSL's heartbeat functionality, if enabled would return 64KB of random memory in plaintext to any client or server requesting for a connection. The vulnerability infected almost two-third of internet web servers, including the popular websites. Recently, there has been an arrest of a Canadian teen of stealing usernames, credentials, session IDs and other da
