Cybersecurity researchers today disclosed details of a memory vulnerability in IBM's Db2 family of data management products that could potentially allow a local attacker to access sensitive data and even cause a denial of service attacks. The flaw ( CVE-2020-4414 ), which impacts IBM Db2 V9.7, V10.1, V10.5, V11.1, and V11.5 editions on all platforms , is caused by improper usage shared memory, thereby granting a bad actor to perform unauthorized actions on the system. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service, according to Trustwave SpiderLabs security and research team, which discovered the issue. "Developers forgot to put explicit memory protections around the shared memory used by the Db2 trace facility," SpiderLabs's Martin Rakhmanov said. "This allows any local users read and write access to that memory area. In turn, this allows accessing critic...

One new security technology we keep hearing about is Extended Detection and Response (XDR). This new technology merges multiple prevention and detection technologies on a single platform to better understand threat signals so that you don't need to purchase, integrate, and manage various control and integration technologies. Think of XDR as prepackaged EDR, NTA, UEBA (and perhaps other prevention and detection) technologies all tightly integrated on a SOAR-like platform. Of course, you don't need SOAR technology with XDR as the entire platform is integrated and orchestrated out of the box. In Gartner's recently published Top 9 Security and Risk Trends for 2020 , XDR was listed first. Cybersecurity company Cynet just released an interesting XDR eBook [ Download it here ] that provides an excellent primer on this promising new technology. According to Cynet, the expense and issues involved with combining multiple siloed control technologies usually make an effort n...

Cybersecurity researchers today took the wraps off a sophisticated, multi-functional peer-to-peer (P2P) botnet written in Golang that has been actively targeting SSH servers since January 2020. Called " FritzFrog ," the modular, multi-threaded and file-less botnet has breached more than 500 servers to date, infecting well-known universities in the US and Europe, and a railway company, according to a report released by Guardicore Labs today. "With its decentralized infrastructure, it distributes control among all its nodes," Guardicore 's Ophir Harpaz said. "In this network with no single point-of-failure, peers constantly communicate with each other to keep the network alive, resilient and up-to-date." In addition to implementing a proprietary P2P protocol that's been written from scratch, the communications are done over an encrypted channel, with the malware capable of creating a backdoor on victim systems that grants continued access fo...

Jenkins—a popular open-source automation server software—published an advisory on Monday concerning a critical vulnerability in the Jetty web server that could result in memory corruption and cause confidential information to be disclosed. Tracked as CVE-2019-17638 , the flaw has a CVSS rating of 9.4 and impacts Eclipse Jetty versions 9.4.27.v20200227 to 9.4.29.v20200521—a full-featured tool that provides a Java HTTP server and web container for use in software frameworks. "Jenkins bundles Winstone-Jetty, a wrapper around Jetty, to act as HTTP and servlet server when started using java -jar jenkins.war. This is how Jenkins is run when using any of the installers or packages, but not when run using servlet containers such as Tomcat," read the advisory. "The vulnerability may allow unauthenticated attackers to obtain HTTP response headers that may include sensitive data intended for another user." The flaw , which impacts Jetty and Jenkins Core, appears to...

Emotet, a notorious email-based malware behind several botnet-driven spam campaigns and ransomware attacks, contained a flaw that allowed cybersecurity researchers to activate a kill-switch and prevent the malware from infecting systems for six months. "Most of the vulnerabilities and exploits that you read about are good news for attackers and bad news for the rest of us," Binary Defense's James Quinn said. "However, it's important to keep in mind that malware is software that can also have flaws. Just as attackers can exploit flaws in legitimate software to cause harm, defenders can also reverse-engineer malware to discover its vulnerabilities and then exploit those to defeat the malware." The kill-switch was alive between February 6, 2020, to August 6, 2020, for 182 days, before the malware authors patched their malware and closed the vulnerability. Since its first identification in 2014, Emotet has evolved from its initial roots as a banking ...

Web applications suffer continuously evolving attacks, where a web application firewall (WAF) is the first line of defense and a necessary part of organizations' cybersecurity strategies. WAFs are getting more sophisticated all the time, but as its core protection starts with efficient pattern matching, typically using Regular Expressions, and classifying malicious traffic to block cyber attacks. Evading pattern matching However, unfortunately, this technique is no silver bullet against determined attackers. Once it's known that there is a protection layer enabled, malicious actors find ways to bypass it, and most of the time, they even succeed. It usually can be achieved when the same attacking payload, blocked by WAF , can be disguised to make it 'invisible' to the pattern matching mechanism to evade security. Context-Specific Obfuscation The web uses many technologies, and they all have different rules for what comprises valid syntax in their grammar...

A team of academic researchers—who previously made the headlines earlier this year for uncovering severe security issues in the 4G LTE and 5G networks —today presented a new attack called ' ReVoLTE ,' that could let remote attackers break the encryption used by VoLTE voice calls and spy on targeted phone calls. The attack doesn't exploit any flaw in the Voice over LTE (VoLTE) protocol; instead, it leverages weak implementation of the LTE mobile network by most telecommunication providers in practice, allowing an attacker to eavesdrop on the encrypted phone calls made by targeted victims. VoLTE or Voice over Long Term Evolution protocol is a standard high-speed wireless communication for mobile phones and data terminals, including Internet of things (IoT) devices and wearables, deploying 4G LTE radio access technology. The crux of the problem is that most mobile operators often use the same keystream for two subsequent calls within one radio connection to encrypt th...

Attention! If you use Amazon's voice assistant Alexa in you smart speakers, just opening an innocent-looking web-link could let attackers install hacking skills on it and spy on your activities remotely. Check Point cybersecurity researchers—Dikla Barda, Roman Zaikin and Yaara Shriki—today disclosed severe security vulnerabilities in Amazon's Alexa virtual assistant that could render it vulnerable to a number of malicious attacks. According to a new report released by Check Point Research and shared with The Hacker News, the "exploits could have allowed an attacker to remove/install skills on the targeted victim's Alexa account, access their voice history and acquire personal information through skill interaction when the user invokes the installed skill." "Smart speakers and virtual assistants are so commonplace that it's easy to overlook just how much personal data they hold, and their role in controlling other smart devices in our homes,...

New research disclosed a string of severe security vulnerabilities in the ' Find My Mobile '—an Android app that comes pre-installed on most Samsung smartphones—that could have allowed remote attackers to track victims' real-time location, monitor phone calls, and messages, and even delete data stored on the phone. Portugal-based cybersecurity services provider Char49 revealed its findings on Samsung's Find My Mobile Android app at the DEF CON conference last week and shared details with the Hacker News. "This flaw, after setup, can be easily exploited and with severe implications for the user and with a potentially catastrophic impact: permanent denial of service via phone lock, complete data loss with factory reset (SD card included), serious privacy implication via IMEI and location tracking as well as call and SMS log access," Char49's Pedro Umbelino said in technical analysis. The flaws, which work on unpatched Samsung Galaxy S7, S8, and S9+...

As software eats the world, the world faces a software security crisis. The movement to modern software such as cloud technologies and microservice architectures is essential to innovate quickly. Yet, nearly three in four developers say that security slows down Agile and DevOps. Neither developers nor security teams are to blame. DevOps speed is held back by a 15-year-old, scan-based application security (AppSec) model designed for the early 2000s. Traditional security tools cannot keep up with today's rapid development pace or modern application portfolio scale. However, sacrificing security for development speed places critical and confidential personal and business information at risk—from financial to healthcare data—and can disrupt operations or even cause outages. Code Scanners Cannot Meet Modern DevOps Legacy AppSec approaches that rely on point-in-time scanning are plagued by development delays and highly inaccurate results. Scans take many hours, if not days—not id...

Citrix today released patches for multiple new security vulnerabilities affecting its Citrix Endpoint Management (CEM) , also known as XenMobile, a product made for enterprises to help companies manage and secure their employees' mobile devices remotely. Citrix Endpoint Management offers businesses mobile device management (MDM) and mobile application management (MAM) capabilities. It allows companies to control which apps their employees can install while ensuring updates and security settings are applied to keep business information protected.

"Remediations have already been applied to cloud versions, but hybrid rights users need to apply the upgrades to any on-premises instance," the company sai d in a post today. If left unpatched and exploited successfully,...

If you haven't recently updated your Chrome, Opera, or Edge web browser to the latest available version, it would be an excellent idea to do so as quickly as possible. Cybersecurity researchers on Monday disclosed details about a zero-day flaw in Chromium-based web browsers for Windows, Mac and Android that could have allowed attackers to entirely bypass Content Security Policy (CSP) rules since Chrome 73. Tracked as CVE-2020-6519 (rated 6.5 on the CVSS scale), the issue stems from a CSP bypass that results in arbitrary execution of malicious code on target websites. According to PerimeterX, some of the most popular websites, including Facebook, Wells Fargo, Zoom, Gmail, WhatsApp, Investopedia, ESPN, Roblox, Indeed, TikTok, Instagram, Blogger, and Quora, were susceptible to the CSP bypass. Interestingly, it appears that the same flaw was also highlighted by Tencent Security Xuanwu Lab more than a year ago, just a month after the release of Chrome 73 in March 2019, but...

A security researcher earlier today publicly revealed details and proof-of-concept exploit code for an unpatched, critical zero-day remote code execution vulnerability affecting the widely used internet forum software vBulletin that's already under active exploitation in the wild. vBulletin is a widely used proprietary Internet forum software package based on PHP and MySQL database server that powers over 100,000 websites on the Internet, including Fortune 500 and Alexa Top 1 million companies websites and forums. In September last year, a separate anonymous security researcher publicly disclosed a then-zero-day RCE vulnerability in vBulletin , identified as CVE-2019-16759 , and received a critical severity rating of 9.8, allowing attackers to execute malicious commands on the remote server without requiring any authentication to log into the forum. A day after the disclosure of CVE-2019-16759, the vBulletin team released security patches that resolved the issue, but it t...
