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. However, the standard process of 3rd party threat assessment as practiced today is both time consuming and expensive. Cynet changes the rules of the game with a free threat assessment offering ( click here to learn more ) based on more than 72 hours of data collection, enabling organizations to benchmark their security posture against their vertical industry peers and take actions accordingly. Cynet Free Threat Assessment (available for organizations with 250 endpoints and above, from North America and Europe) spotlights critical, exposed attack surfaces and provides actionable knowledge of attacks that are currently alive and active in the environment. 1.) Indication of live attacks — active malware, connection to C&C, data exfiltration, access to phishing links, user credential theft attempts, and others: 2.) Host and app attack surfaces — unpatched vulnera...

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 ...
