Popular enterprise software company Citrix that provides services to the U.S. military, the FBI, many U.S. corporations, and various U.S. government agencies disclosed last weekend a massive data breach of its internal network by "international cyber criminals." Citrix said it was warned by the FBI on Wednesday of foreign hackers compromising its IT systems and stealing "business documents," adding that the company does not know precisely which documents the hackers obtained nor how they got in. However, the FBI believes that the miscreants likely used a "password spraying" attack where the attackers guessed weak passwords to gain an early foothold in the company's network in order to launch more extensive attacks. "While not confirmed, the FBI has advised that the hackers likely used a tactic known as password spraying, a technique that exploits weak passwords. Once they gained a foothold with limited access, they worked to circumvent

You must update your Google Chrome immediately to the latest version of the web browsing application. Security researcher Clement Lecigne of Google's Threat Analysis Group discovered and reported a high severity vulnerability in Chrome late last month that could allow remote attackers to execute arbitrary code and take full control of the computers. The vulnerability, assigned as CVE-2019-5786 , affects the web browsing software for all major operating systems including Microsoft Windows, Apple macOS, and Linux. Without revealing technical details of the vulnerability, the Chrome security team only says the issue is a use-after-free vulnerability in the FileReader component of the Chrome browser, which leads to remote code execution attacks. What's more worrisome? Google warned that this zero-day RCE vulnerability is actively being exploited in the wild by attackers to target Chrome users. "Access to bug details and links may be kept restricted until a majo

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1. Know Thy Endpoints: Identifying and Understanding Your Entry Points Understanding your network's

Google's one-year-old cybersecurity venture Chronicle today announced its first commercial product, called Backstory , a cloud-based enterprise-level threat analytics platform that has been designed to help companies quickly investigate incidents, pinpoint vulnerabilities and hunt for potential threats. Network infrastructures at most enterprises regularly generate enormous amounts of network data and logs on a daily basis that can be helpful to figure out exactly what happened when a security incident occurs. However, unfortunately, most companies either don't collect the right telemetry or even when they do, it's practically impossible for them to retain that telemetry for more than a week or two, making analysts blind if any security incident happens before that. Backstory solves this problem by allowing organizations to privately upload and store their petabytes of "internal security telemetry" on Google cloud platform and leverage machine learning and da

Security researchers have finally, with "high confidence," linked a previously discovered global cyber espionage campaign targeting critical infrastructure around the world to a North Korean APT hacking group. Thanks to the new evidence collected by researchers after analyzing a command-and-control (C2) server involved in the espionage campaign and seized by law enforcement. Dubbed Operation Sharpshooter , the cyber espionage campaign targeting government, defense, nuclear, energy, and financial organizations around the world was initially uncovered in December 2018 by security researchers at McAfee. At that time, even after finding numerous technical links to the North Korean Lazarus hacking group , researchers were not able to immediately attribute the campaign due to a potential for false flags. Researchers Analysed Sharpshooter's Command Server Now, according to a press release shared with The Hacker News, a recent analysis of the seized code and command

Cybersecurity researcher at Google's Project Zero division has publicly disclosed details and proof-of-concept exploit of a high-severity security vulnerability in macOS operating system after Apple failed to release a patch within 90 days of being notified. Discovered by Project Zero researcher Jann Horn and demonstrated by Ian Beer, the vulnerability resides in the way macOS XNU kernel allows an attacker to manipulate filesystem images without informing the operating system. The flaw could eventually allow an attacker or a malicious program to bypass the copy-on-write (COW) functionality to cause unexpected changes in the memory shared between processes, leading to memory corruption attacks. Copy-On-Write, also referred to as COW, is a resource-management optimization strategy used in computer programming. In general, if any process (destination) requires a file or data that is already in the memory but created by another process (source), both processes can share the

Coinhive, a notorious in-browser cryptocurrency mining service popular among cybercriminals, has announced that it will discontinue its services on March 8, 2019. Regular readers of The Hacker News already know how Coinhive's service helped cyber criminals earn hundreds of thousands of dollars by using computers of millions of people visiting hacked websites . For a brief recap: In recent years, cybercriminals leveraged every possible web vulnerability [in Drupal , WordPress , and others ] to hack thousands of websites and wireless routers , and then modified them to secretly inject Coinhive's JavaScript-based Monero (XMR) cryptocurrency mining script on web-pages to financially benefit themselves. Millions of online users who visited those hacked websites immediately had their computers' processing power hijacked, also known as cryptojacking , to mine cryptocurrency without users' knowledge, potentially generating profits for cybercriminals in the background.

Security researchers have discovered two high-severity vulnerabilities in the SHAREit Android app that could allow attackers to bypass device authentication mechanism and steal files containing sensitive from a victim's device. With over 1.5 billion users worldwide, SHAREit is a popular file sharing application for Android, iOS, Windows and Mac that has been designed to help people share video, music, files, and apps across various devices. With more than 500 million users, the SHAREit Android app was found vulnerable to a file transfer application's authentication bypass flaw and an arbitrary file download vulnerability, according to a blog post RedForce researchers shared with The Hacker News. The vulnerabilities were initially discovered over a year back in December 2017 and fixed in March 2018, but the researchers decided not to disclose their details until Monday "given the impact of the vulnerability, its big attack surface and ease of exploitation."
