Cybersecurity researchers today uncovered a new high-severity hardware vulnerability residing in the widely-used Wi-Fi chips manufactured by Broadcom and Cypress—apparently powering over a billion devices, including smartphones, tablets, laptops, routers, and IoT gadgets. Dubbed ' Kr00k ' and tracked as CVE-2019-15126 , the flaw could let nearby remote attackers intercept and decrypt some wireless network packets transmitted over-the-air by a vulnerable device. The attacker does not need to be connected to the victim's wireless network and the flaw works against vulnerable devices using WPA2-Personal or WPA2-Enterprise protocols, with AES-CCMP encryption, to protect their network traffic. "Our tests confirmed some client devices by Amazon (Echo, Kindle), Apple (iPhone, iPad, MacBook), Google (Nexus), Samsung (Galaxy), Raspberry (Pi 3), Xiaomi (RedMi), as well as some access points by Asus and Huawei, were vulnerable to Kr00k," ESET researchers said. Acc...

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...

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, ...

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...

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...

Cybersecurity researchers have discovered a large-scale ongoing fraud scheme that lures unsuspecting Russian Internet users with promises of financial rewards to steal their payment card information. According to researchers at Group-IB , the multi-stage phishing attack exploited the credibility of Russian Internet portal Rambler to trick users into participating in a fictitious "Like of the Year 2020" contest. The development is a reminder that rewards-based social engineering campaigns continue to be an effective means to scam users, not to mention the leveraging the collected data to their financial advantage. Under the "Like of the Year" scheme, users were invited to win a large cash prize, telling them they've been randomly selected after liking a post on social media platforms such as VKontakte. The invites were sent via an email blast by hacking the mail servers of a fiscal data operator , which refers to a legal entity created to aggregate, st...

Adobe today released out-of-band software updates for After Effects and Media Encoder applications that patch a total of two new critical vulnerabilities. Both critical vulnerabilities exist due to out-of-bounds write memory corruption issues and can be exploited to execute arbitrary code on targeted systems by tricking victims into opening a specially crafted file using the affected software. The bug ( CVE-2020-3765 ) in Adobe After Effects, an application for creating motion graphics and special effects used in the video, was discovered by security researcher Matt Powell and reported to Adobe via Trend Micro Zero Day Initiative project. Whereas, the second issue ( CVE-2020-3764 ) affecting Adobe Media Encoder, software for encoding and compressing audio or video files, was discovered by Canadian security researcher Francis Provencher. None of the security vulnerabilities fixed in this batch of Adobe updates were publicly disclosed or found being exploited in the wild, as th...

Smart doorbells and cameras bring a great sense of security to your home, especially when you're away, but even a thought that someone could be spying on you through the same surveillance system would shiver up your spine. Following several recent reports of hackers gaining access to people's internet-connected Ring doorbell and security cameras, Amazon yesterday announced to make two-factor authentication security feature mandatory for all Ring users. Until now, enabling the two-factor authentication in Ring devices was optional, which definitely would have prevented most Ring hacks, but of course, many never bothered to enable it. That means, from now onwards, at the time of login after entering the account's username and password, every user needs to input a secret six-digit authentication code sent to them via their phone or email. Two-factor authentication is an effective defense because it acts as a deterrent, preventing unauthorized users from gaining acces...

The U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) earlier today issued a warning to all industries operating critical infrastructures about a new ransomware threat that if left unaddressed could have severe consequences. The advisory comes in response to a cyberattack targeting an unnamed natural gas compression facility that employed spear-phishing to deliver ransomware to the company's internal network, encrypting critical data and knocking servers out of operation for almost two days. "A cyber threat actor used a spear-phishing link to obtain initial access to the organization's information technology network before pivoting to its operational technology network. The threat actor then deployed commodity ransomware to encrypt data for impact on both networks," CISA noted in its alert. As ransomware attacks continue to escalate in frequency and scale , the new development is yet another indication that p...

A new report published by cybersecurity researchers has unveiled evidence of Iranian state-sponsored hackers targeting dozens of companies and organizations in Israel and around the world over the past three years. Dubbed " Fox Kitten ," the cyber-espionage campaign is said to have been directed at companies from the IT, telecommunication, oil and gas, aviation, government, and security sectors. "We estimate the campaign revealed in this report to be among Iran's most continuous and comprehensive campaigns revealed until now," ClearSky researchers said . "The revealed campaign was used as a reconnaissance infrastructure; however, it can also be used as a platform for spreading and activating destructive malware such as ZeroCleare and Dustman." Tying the activities to threat groups APT33, APT34, and APT39, the offensive — conducted using a mix of open source and self-developed tools — also facilitated the groups to steal sensitive information...

Visibility into an environment attack surface is the fundamental cornerstone to sound security decision making.

A popular WordPress theme plugin with over 200,000 active installations contains a severe but easy-to-exploit software vulnerability that, if left unpatched, could let unauthenticated remote attackers compromise a wide range of websites and blogs. The vulnerable plugin in question is ' ThemeGrill Demo Importer ' that comes with free as well as premium themes sold by the software development company ThemeGrill. ThemeGrill Demo Importer plugin has been designed to allow WordPress site admins to import demo content, widgets, and settings from ThemeGrill, making it easier for them to quickly customize the theme. According to a report WebARX security company shared with The Hacker News, when a ThemeGrill theme is installed and activated, the affected plugin executes some functions with administrative privileges without checking whether the user running the code is authenticated and is an admin. The flaw could eventually allow unauthenticated remote attackers to wipe the e...

Here's excellent news for sysadmins. You can now use a physical security key as hardware-based two-factor authentication to securely log into a remote system via SSH protocol. OpenSSH, one of the most widely used open-source implementations of the Secure Shell (SSH) Protocol, yesterday announced the 8.2 version of the software that primarily includes two new significant security enhancements. First, OpenSSH 8.2 added support for FIDO/U2F hardware authenticators , and the second, it has deprecated SSH-RSA public key signature algorithm and planned to disable it by default in the future versions of the software. FIDO (Fast Identity Online) protocol based hardware security devices are stronger and fool-proof mechanisms for authentication because it enables public-key cryptography to protect against advanced malware, phishing, and man-in-the-middle attacks. "In OpenSSH, FIDO devices are supported by new public key types' ecdsa-sk' and 'ed25519-sk', along ...
