Atomic Stealer | Breaking Cybersecurity News | The Hacker News

Malicious ads and bogus websites are acting as a conduit to deliver two different stealer malware, including Atomic Stealer, targeting Apple macOS users. The ongoing infostealer attacks targeting macOS users may have adopted different methods to compromise victims' Macs, but operate with the end goal of stealing sensitive data, Jamf Threat Labs  said  in a report published Friday. One such attack chain targets users searching for Arc Browser on search engines like Google to serve bogus ads that redirect users to look-alike sites ("airci[.]net") that serve the malware. "Interestingly, the malicious website cannot be accessed directly, as it returns an error," security researchers Jaron Bradley, Ferdous Saljooki, and Maggie Zirnhelt said. "It can only be accessed through a generated sponsored link, presumably to evade detection." The disk image file downloaded from the counterfeit website ("ArcSetup.dmg") delivers  Atomic Stealer , which i...

Cybersecurity researchers have identified an updated version of a macOS information stealer called  Atomic  (or AMOS), indicating that the threat actors behind the malware are actively enhancing its capabilities. "It looks like Atomic Stealer was updated around mid to late December 2023, where its developers introduced payload encryption in an effort to bypass detection rules," Malwarebytes' Jérôme Segura  said  in a Wednesday report. Atomic Stealer  first emerged  in April 2023 for a monthly subscription of $1,000. It's capable of harvesting sensitive information from a compromised host, including Keychain passwords, session cookies, files, crypto wallets, system metadata, and the machine's password via a fake prompt. Over the past several months, the malware has been observed propagated via  malvertising  and  compromised sites  under the guise of legitimate software and web browser updates. Malwarebytes' latest analysis shows th...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The macOS information stealer known as Atomic is now being delivered to target via a bogus web browser update chain tracked as ClearFake. "This may very well be the first time we see one of the main social engineering campaigns, previously reserved for Windows, branch out not only in terms of geolocation but also operating system," Malwarebytes' Jérôme Segura  said  in a Tuesday analysis. Atomic Stealer (aka AMOS),  first documented  in April 2023, is a commercial stealer malware family that's sold on a subscription basis for $1,000 per month. It comes with capabilities to siphon data from web browsers and cryptocurrency wallets. Then in September 2023, Malwarebytes  detailed  an Atomic Stealer campaign that took advantage of malicious Google ads, tricking macOS users searching for a financial charting platform known as TradingView into downloading the malware. ClearFake, on the other hand, is a nascent malware distribution operation that employs comp...
