Fake iPhone Duo preorder scam triggers DarkSword attack
Apple announced its first foldable iPhone on September 9, and scammers were ready to ‘deliver’ one before anyone could buy it. Most of what we found around the launch of the iPhone Duo and iPhone 18 Pro was familiar fraud. But one fake preorder page was different. The fake Apple-style page offers a $500 voucher and a ticking preorder deadline. Behind its Apple-style design and $500 voucher, the page uses the leaked DarkSword exploit chain to try to break into vulnerable iPhones. If it succeeds,…

The Developer is the New Perimeter: How Supply Chain Attacks Are Becoming Cloud Breaches
Key Takeaways Malicious packages can steal cloud credentials during installation, before applications run. Stolen credentials turn developer workstations and CI/CD pipelines into gateways to cloud resources. Restrict installation scripts, minimize credential privileges, protect metadata access, and monitor cloud activity. Containment requires revoking exposed credentials and investigating cloud activity beyond removing compromised packages. Qualys TotalCloud connects cloud risk signals, while…

Kothamine malware uses Tailscale’s tailcat to evade network detection

Some versions can also steal browser data and record through the camera and microphone. We found Kothamine linked to malicious npm packages, which could put users and developers who install those packages at risk. In recent versions, the malware…
Criminals turn placeholder domain into ClickFix trap
A domain that has long appeared in software documentation, code examples, and developer test material is now being used to push a ClickFix attack against Windows users. A placeholder domain stands in for a website in an example. The best-known is probably example.com. Another, third-party[.]com, has often been used in documentation to represent an external website, API, or service. However, there is a very important difference between the two: example.com is reserved for documentation, while…

A Closer Look at Malware From the Macfinger ClickFix Campaign, (Fri, Sep 25th)
Introduction My previous post on Macfinger ClickFix was two days ago, and this campaign remains active. The more I look into the malware delivered by this campaign, the more I believe it is not a variant of Atomic macOS (AMOS) Stealer as originally reported. There are too many differences between what I've documented with recent AMOS Stealer activity and what I'm now seeing with this malware. The data collection and method of exfiltration is different between these two malware families. The…

MacSync under the microscope: new delivery methods and a new payload
MacSync is a relatively young, rapidly evolving family of crypto/info stealers. First advertised on the dark web in 2025 as Mac.c, the stealer was later renamed to MacSync by its creators. The initial versions were implemented as AppleScripts and closely resembled the AMOS stealer family, but over time, MacSync developed distinctive features of its own, including a backdoor module. In this report, we discuss a new infection chain that differs significantly from previous variants. We first…

Introduction I've found several legitimate websites with injected script for a campaign using the ClickFix social engineering technique.

No, this is not related to the MacFinger utility from decades ago. Instead, think of…

Introducing CAIRN: Frontier tracking for AI-integrated malware

When we consider these strings as cognitive artifacts, or vestiges left behind from AI integration, we can enable a new, metadata…

New Android malware uses AI to steal bank logins and PINs
Researchers at Zimperium’s zLabs have analyzed an Android Trojan that uses an automated, multi-stage infection process.

The variable attack path makes it harder for signature- and rule-based mobile security tools to detect this Trojan. It also abuses Android Debug Bridge (ADB), a legitimate tool…
