![]() In August 2022, the Apple Support site published security updates for iOS 15.6.1 and iPadOS 15.6.1 and macOS Monterey 12.5.1. Soon after, in April 2012, a new Mac OS X trojan was discovered.įast forward to the present day, and the vulnerabilities continue to multiply. The Mac OS, once considered a haven against viruses, had fallen. News of Flashback shook the entire cybersecurity and tech industry. The rogue sites had Flashback exploits installed on them to execute the malware. The browser could then perform a hidden redirect to sites in the rr.nu domain zone. When any of the infected sites were visited, a tabular data stream (TDS) was contacted. Approximately 85% of the compromised sites were located in the US. This might have occurred due to site owners using vulnerable WordPress versions or installing the ToolsPack plugin. By early March 2012, the program had infected tens of thousands of sites powered by WordPress. The program implemented script redirects from huge numbers of legitimate websites worldwide. Infected Through WordPressĪccording to Kaspersky, Flashback malware spread thanks to a threat partner program that appeared to be of Russian origin. From there, criminals raked in click-generated revenue totaling about $10,000 per day. The trojan’s ad-clicking component loaded into Chrome, Firefox and Safari, where it could intercept browser requests and redirect specific search queries to a page of the attacker’s choosing. One of the malware’s objectives was to generate fake search engine results.Īccording to researchers, threat actors used Flashback to siphon Google ad revenue. After infection, compromised PCs were recruited into a botnet that enabled the installation of additional malicious code. By March 2012, the trojan had infected around 700,000 computers worldwide. What is the Mac Flashback Trojan?įlashback (also called Flashfake) is a type of Mac OS X malware first detected in September 2011. In this post, we’ll revisit how the Flashback incident unfolded and how it changed the security landscape forever. Since then, Mac and iPhone security issues have changed dramatically - and so has the security of the entire world. But that was before the Mac OS X Trojan Flashback malware appeared in 2012. In fact, Apple once stated on its website that “it doesn’t get PC viruses”. More information about Apple’s Java update and Flashback removal tool is available here.Not so long ago, the Mac was thought to be impervious to viruses. However, in Intego’s tests, this alert displayed very quickly, and disappeared almost immediately. If Apple’s Flashback removal tool does find that you are infected with one of the “most common variants of Flashback,” it will remove the malware, and display an alert. A free 30-day demo is available, and you can use this to check your Mac to see if it is infected. ![]() Intego’s Mac antivirus, VirusBarrier X6, will remove all known variants of the Flashback malware. However, the Apple Flashback removal tool only removes “the most common variants of the Flashback malware.” We are not sure which variants this covers Intego currently has 18 variants, from Flashback.A to Flashback.R, and Apple’s tool clearly does not detect and remove all of them. It does not immediately deactivate Java in Safari, however, so if you do use Java applets on web sites, this will not affect your browsing. In addition, this update will deactivate the Java browser plug-in, and Java Web Start, if they are unused for 35 days.
