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...

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. ...
