Cybersecurity Threat Research 'Weekly' Recap. Attackers abused fake installers, developer-platform lures, and AI-driven tooling to deliver loaders and steal credentials, including campaigns tied to Silver Fox, GlassWorm, JSCEAL, TA419, Remcos, and Vidar. Alongside these tradecraft shifts, the roundup highlighted active zero-day exploitation in Citrix NetScaler and PaperCut MF, plus supply-chain and exposed-credential risks involving MALFEX and leaked GitHub datasets. #SilverFox #GlassWorm #JSCEAL #TA419 #Remcos #Vidar #CitrixNetScaler #CVE-2026-88771 #CVE-2026-88772 #PaperCutMF #AdaptixC2 #MALFEX #TIKTOUK #Jewelbug #Warlock

JSCEAL is being distributed through Facebook ads that impersonate a cryptocurrency exchange and lure users to fake installation pages that generate platform-specific installers for Windows and macOS. Over about two months, infections were confirmed on roughly 1,500 PCs in Korea, with attackers using BAT and PKG files, PowerShell, scheduled tasks, LaunchAgent...

DarkSword, JSCeal, Axios, Bitter APT, and APT28 campaigns reveal evolving tactics targeting iPhones, Southeast Asia, software supply chains, diplomatic organizations, and European governments.

JSCeal hides crypto-stealing malware in V8 bytecode, but researchers built a tool to decompile it and expose its advanced theft capabilities. JSCeal is a cryptocurrency stealer that Check Point Research has tracked since early 2025. Unlike most malware, it hides its code in a format that makes analysis much harder. Check Point presented its latest […]

Cybersecurity researchers have unpacked JSCeal, a sophisticated compiled V8 JavaScript (JSC) malware with credential harvesting, surveillance, and traffic-interception capabilities. "The payloads are protected with javascript-obfuscator, using multiple techniques including RC4-protected strings, control-flow flattening, proxy functions, and operation wrappers," Check Point Research said in a

JSCeal is a cryptocurrency stealer that Check Point Research has tracked since early 2025. The malware hides its code in V8 bytecode format, which makes analysis more difficult than typical malware. Researchers built a tool to decompile the V8 bytecode and expose the malware's advanced theft capabilities. Check Point presented its findings on this crypto-stealing malware that uses an unconventional obfuscation technique to evade detection.
