Check Point's deobfuscation of 23 compiled V8 bytecode samples shows JSCeal replaying stolen cookies inside the victim's own browser profile, then stuffing local credentials at any password prompt until it holds a fresh OAuth token.

CSO Online's teardown of a Webworm implant found an upgrade command that replaces all five credential strings in a single task. The revocation step at the top of most identity runbooks costs the operator one poll cycle.

Sophos found the timezone_check implant on compromised Cisco Firewall Management Center devices in August 2026 and assessed it likely Sandworm's work. Generic SysV persistence replaces the firmware trick and widens the appliances it can run on.

A researcher says an unreported campaign used a fake GSTR-3B overdue notice ahead of the 20 August filing deadline, delivering a patched DLL that a genuinely signed Microsoft binary loads.

Computer Weekly says a Czech firm rehacked France's EncroChat implant and found GitHub exploit code for Bad Binder, an Android bug unpatched in 2.5 billion phones. Lawyers expect a stalled UK case to restart.

Coveware says four bytes of the per-file public key get overwritten on the stack, so no private key exists for anything Nitrogen encrypted on ESXi. Not even the attacker can undo it.

Unit 42 says the C++ loader reads encrypted commands from immutable smart contracts over public RPC endpoints, which turns takedown work into traffic monitoring.
