Firefox enables DNS-over-HTTPS by default (with Cloudflare) for all U.S. users

Firefox enables DNS-over-HTTPS by default (with Cloudflare) for all U.S. users

February 25, 2020Mohit Kumar
If you use the Firefox web browser, here's an important update that you need to be aware of. Starting today, Mozilla is activating the DNS-over-HTTPS security feature by default for all Firefox users in the U.S. by automatically changing their DNS server configuration in the settings. That means, from now onwards, Firefox will send all your DNS queries to the Cloudflare DNS servers instead of the default DNS servers set by your operating system, router, or network provider. As you may know, DNS-over-HTTPS (DoH) protocol performs DNS lookups — i.e., finding the server I.P. address of a certain domain name — over an encrypted connection to a DNS server rather than sending queries in the plaintext. This privacy-focused technology makes it harder for man-in-the-middle attackers, including your ISPs, to manipulate DNS queries, eavesdrop on your Internet connection, or learning what sites you visit. "This helps hide your browsing history from attackers on the network,

Install Latest Chrome Update to Patch 0-Day Bug Under Active Attacks

February 25, 2020Ravie Lakshmanan
Google yesterday released a new critical software update for its Chrome web browser for desktops that will be rolled out to Windows, Mac, and Linux users over the next few days. The latest Chrome 80.0.3987.122 includes security fixes for three new vulnerabilities , all of which have been marked 'HIGH' in severity, including one that (CVE-2020-6418) has been reportedly exploited in the wild. The brief description of the Chrome bugs, which impose a significant risk to your systems if left unpatched, are as follows: Integer overflow in ICU — Reported by AndrĂ© Bargull on 2020-01-22 Out of bounds memory access in streams (CVE-2020-6407) — Reported by Sergei Glazunov of Google Project Zero on 2020-01-27 Type confusion in V8 (CVE-2020-6418) — Reported by Clement Lecigne of Google's Threat Analysis Group on 2020-02-18 The Integer Overflow vulnerability was disclosed by AndrĂ© Bargull privately to Google last month, earning him $5,000 in rewards, while the other two
New OpenSMTPD RCE Flaw Affects Linux and OpenBSD Email Servers

New OpenSMTPD RCE Flaw Affects Linux and OpenBSD Email Servers

February 25, 2020Mohit Kumar
OpenSMTPD has been found vulnerable to yet another critical vulnerability that could allow remote attackers to take complete control over email servers running BSD or Linux operating systems. OpenSMTPD , also known as OpenBSD SMTP Server, is an open-source implementation of the Simple Mail Transfer Protocol (SMTP) to deliver messages on a local machine or to relay them to other SMTP servers. It was initially developed as part of the OpenBSD project but now comes pre-installed on many UNIX-based systems. Discovered by experts at Qualys Research Labs, who also reported a similar RCE flaw in the email server application last month, the latest out-of-bounds read issue, tracked as  CVE-2020-8794 , resides in a component of the OpenSMTPD's client-side code that was introduced nearly 5 years ago. Just like the previous issue, which attackers started exploiting in the wild just a day after its public disclosure, the new OpenSMTPD flaw could also let remote hackers execute arbit
Why Minimizing Human Error is the Only Viable Defense Against Spear Phishing

Why Minimizing Human Error is the Only Viable Defense Against Spear Phishing

February 25, 2020The Hacker News
Phishing attacks have become one of the business world's top cybersecurity concerns. These social engineering attacks have been rising over the years, with the most recent report from the Anti-Phishing Working Group coalition identifying over 266,000 active spoofed websites, which is nearly double the number detected during Q4 2018. Hackers have evolved their methods, from regular phishing attacks to spear phishing, where they use email messages disguised as coming from legitimate sources to dupe specific individuals. This is why the global spear phishing protection software market is estimated to reach $1.8 billion by 2025. However, conventional defenses can still fall short due to one particular weakness in the security perimeter – the human factor. Indeed, some 33 percent of 2019's data breaches involved humans falling victim to social engineering attacks. And given how sophisticated and creative the phishing perpetrators have been getting, it's easy to see h

Google Bans 600 Android Apps from Play Store for Serving Disruptive Ads

Google Bans 600 Android Apps from Play Store for Serving Disruptive Ads

February 21, 2020Ravie Lakshmanan
Google has banned nearly 600 Android apps from the Play Store for bombarding users with disruptive ads and violating its advertising guidelines. The company categorizes disruptive ads as "ads that are displayed to users in unexpected ways, including impairing or interfering with the usability of device functions," such as a full-screen ad served when attempting to make a phone call. Although Google didn't name the specific apps in question, many of the apps — which had been installed more than 4.5 billion times — primarily targeted English-speaking users and were mainly from developers based in China, Hong Kong, Singapore, and India, according to Buzzfeed News. Highlighting that malicious developers are getting "more savvy in deploying and masking disruptive ads," the company said it has developed new counter mechanisms to detect such behavior. Trouble in Google Play Store This is not the first time adware apps have been removed from the Google P
