A group of academics from Ruhr University Bochum and New York University Abu Dhabi have uncovered security flaws in 4G LTE and 5G networks that could potentially allow hackers to impersonate users on the network and even sign up for paid subscriptions on their behalf. The impersonation attack — named " IMPersonation Attacks in 4G NeTworks " (or IMP4GT ) — exploits the mutual authentication method used by the mobile phone and the network's base station to verify their respective identities to manipulate data packets in transit. "The IMP4GT attacks exploit the missing integrity protection for user data, and a reflection mechanism of the IP stack mobile operating system. We can make use of the reflection mechanism to build an encryption and decryption oracle. Along with the lack of integrity protection, this allows to inject arbitrary packets and to decrypt packets," the researchers explained. The research was presented at the Network Distributed System Se

Google today published a blog post recommending mobile app developers to encrypt data that their apps generate on the users' devices, especially when they use unprotected external storage that's prone to hijacking. Moreover, considering that there are not many reference frameworks available for the same, Google also advised using an easy-to-implement security library available as part of its Jetpack software suite. The open-sourced Jetpack Security (aka JetSec) library lets Android app developers easily read and write encrypted files by following best security practices , including storing cryptographic keys and protecting files that may contain sensitive data, API keys, OAuth tokens. To give a bit of context, Android offers developers two different ways to save app data. The first one is app-specific storage, also known as internal storage, where the files are stored in a sandboxed folder meant for a specific app's use and inaccessible to other apps on the same

Over the past two years, a shocking  51% of organizations surveyed in a leading industry report have been compromised by a cyberattack.  Yes, over half.  And this, in a world where enterprises deploy  an average of 53 different security solutions  to safeguard their digital domain.  Alarming? Absolutely. A recent survey of CISOs and CIOs, commissioned by Pentera and conducted by Global Surveyz Research, offers a quantifiable glimpse into this evolving battlefield, revealing a stark contrast between the growing risks and the tightening budget constraints under which cybersecurity professionals operate. With this report, Pentera has once again taken a magnifying glass to the state of pentesting to release its annual report about today's pentesting practices. Engaging with 450 security executives from North America, LATAM, APAC, and EMEA—all in VP or C-level positions at organizations with over 1,000 employees—the report paints a current picture of modern security validation prac

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,

You are a cybersecurity professional with the responsibility to keep your organization secured, you know your job chapter and verse, from high level reporting duties to the bits and bytes of what malware targeted your endpoints a week ago. But it's a lot to hold in one's mind, so to make your life easier, The Ultimate Security Pros' Checklist , created by Cynet, provides you with a concise and actionable checklist enabling you to keep track of all your operational, management and reporting tasks. 'We are constantly interacting with the security managers of our customers,' says Eyal Gruner, founder, and CEO of Cynet, 'and this gives us a unique perspective on what are the core duties they all care about. So, you can think of the checklist templates as an aggregated crowd-sourcing from the numerous CISOs, security directors, architects, and SOC managers we have worked with across the years.' The Ultimate Security Pros' Checklist fully maps the co

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 André 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 André Bargull privately to Google last month, earning him $5,000 in rewards, while the other two

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

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
