New details have emerged about a vast network of rogue extensions for Chrome and Edge browsers that were found to hijack clicks to links in search results pages to arbitrary URLs, including phishing sites and ads. Collectively called "CacheFlow" by Avast, the 28 extensions in question - including Video Downloader for Facebook, Vimeo Video Downloader, Instagram Story Downloader, VK Unblock - made use of a sneaky trick to mask its true purpose: Leverage Cache-Control HTTP header as a covert channel to retrieve commands from an attacker-controlled server.
Seven vulnerabilities have been found in a popular DNS caching proxy and DHCP server known as dnsmasq, raising the possibility of widespread online attacks on networking devices. Dnsmasq 2.83, maintained by open source software developer Simon Kelley, has been released to address the issues, which recall the DNS cache poisoning vulnerability identified in 2008 by security researcher Dan Kaminsky.
The set of seven flaws are comprised of buffer overflow issues and flaws allowing for DNS cache-poisoning attacks. If exploited, these flaws could be chained together to allow remote code execution, denial of service and other attacks.

Reseachers are raising the alarm for a newly identified operation leveraging a new Remote Access Tool written in Golang to steal crypto-currency from unsuspecting users. Discovered last month, the campaign is believed to have been active since January 2020, consisting of a fully-fledged marketing campaign, custom applications related to crypto-currency, fake social media accounts, websites, and the new RAT, which Intezer calls ElectroRAT. Widely undetected, the Golang backdoor is written from scratch and is designed to target Windows, Linux, and macOS. To lure crypto-currency users into downloading Trojanized apps, the threat actor behind the campaign promoted the tools on crypto-currency and blockchain forums, as well as on social media platforms.
Microsoft on Thursday took the wraps off an ongoing campaign impacting popular web browsers that stealthily injects malware-infested ads into search results to earn money via affiliate advertising. The campaign - which impacts Microsoft Edge, Google Chrome, Yandex Browser, and Mozilla Firefox browsers on Windows - aims to insert additional, unauthorized ads on top of legitimate ads displayed on search engine results pages, leading users to click on these ads inadvertently.
For at least the third time in its existence, OGUsers - a forum overrun with people looking to buy, sell and trade access to compromised social media accounts - has been hacked.
