MacSync malware hides payloads in public iCloud calendars

A newly spotted variant of the MacSync infostealer is using public iCloud calendar events to deliver its next-stage payloads to macOS systems, according to Kaspersky researchers.

MacSync is written in Swift and first appeared in April 2025. It has recently been pushed through ClickFix campaigns, in which victims are tricked into running commands themselves. Those lures posed as Homebrew and as macOS tools for analysing disk space. Kaspersky says earlier versions of MacSync were derived from the AMOS stealer family. Since then, the malware has grown through additional modules.

A fake crypto wallet as bait

The operators rely on social engineering. Besides ClickFix-style attacks, they offer MacSync disguised as free or cracked software, or as brand-new applications.

Bitget hack: $351.6M stolen, North Korea suspected

Cryptocurrency exchange Bitget has disclosed that attackers took $351.6 million from its hot and warm wallets. These are wallets that stay connected to the platform's systems for day-to-day operations. The company links the theft to North Korean hackers.

Bitget spotted the breach on Thursday evening, when its security systems flagged several unauthorized transfers from a small number of crypto wallets. It has paused all withdrawals while it investigates. Law enforcement agencies, on-chain security institutions, and experts from Mandiant and SlowMist are assisting with the investigation.

Cold wallets and customer balances untouched

The exchange says the damage is limited to part of its infrastructure. Its cold wallets, which are kept offline, were not affected. According to the company, most of the assets on the platform are also safe.
