Background for this topic.
A Trojan is malware that masquerades as legitimate, useful, or necessary software so a user or process runs it. “Trojan” describes a delivery or deception technique rather than one malware family; capabilities vary by sample and may include credential theft, surveillance, file manipulation, or remote access. Unlike self-propagating malware, a Trojan generally depends on being installed or executed through some other means.
Security analysis should identify the specific family and executable behavior rather than treating every Trojan as equivalent. Material concerns include untrusted software and tampered installers, execution under excessive privileges, and unauthorized persistence or access to sensitive data. Defenses include using trusted software sources and code-signature or application-control checks, limiting user privileges, monitoring endpoint process and network activity, and isolating suspected hosts. After detection, preserve relevant evidence, remove persistence, assess credential exposure, and investigate other affected systems before returning the device to normal use.
Cybersecurity researchers have discovered a new version of the SparkCat malware on the Apple App Store and Google Play Store, more than a year after the trojan was discovered targeting both the mobile operating systems
Augmented Marauder's multipronged banking-Trojan cyber campaigns are targeting Spanish speakers, evading detection, and replicating rapidly.
Expect Fallout After Remote Access Trojan Added to Popular JavaScript NPM PackageA supply-chain attack backdoored versions of Axios, a popular JavaScript library that's present in many different software packages, to distribute a cross-platform, remote access Trojan. Identifying the full fallout from the attack could take some time, experts warned.
Chinese-speaking users are the target of an active campaign that uses typosquatted domains impersonating trusted software brands to deliver a previously undocumented remote access trojan named AtlasCross RAT
Hijacked maintainer account let attackers slip cross-platform trojan into 100M-downloads-a-week Axios Updated One of npm's most widely used HTTP client libraries briefly became a malware delivery vehicle after attackers hijacked a maintainer's account and slipped a remote-access trojan (RAT) into two seemingly legitimate axios releases, in what's being described as "one of the most impactful npm supply chain attacks on record."…
The popular HTTP client known as Axios has suffered a supply chain attack after two newly published versions of the npm package introduced a malicious dependency that delivers a trojan capable of targeting Windows, macOS, and Linux systems
