Elastic Security Labs has tracked REF9334, a Brazilian banking malware operation, since May 2025. Its toolkit is called KREMLIN (as named by the malware author, Kr3mlin4rt1st), though nothing about the operation is Russian. Lures impersonate twelve Brazilian banks; error messages and code comments are written in Portuguese, and the operators' Ethereum transactions cluster during São Paulo working hours. Over 15 months and seven campaigns, they built a malicious browser extension that installs…

An attacker breached an email marketing platform and launched targeted attacks against the newsletter subscribers of some of its customers, especially those working in cryptocurrency and adjacent fields. The incident was a supply-chain phishing campaign carried out through Brevo, an email marketing provider used by several cryptocurrency companies and other firms. Brevo initially said an attacker had gained access to 120 customer accounts, some of which were used to send phishing emails to the…
I identified an attacker using a semi-autonomous coding agent to run an offensive operation: finding poorly secured LLM resale gateways, acquiring API access through ordinary web flaws and account farming, validating the resulting inference capacity, and aggregating it behind a single gateway of their own. What I captured was not simply credential theft, but an inference supply chain — an agent harvesting, validating, and consolidating LLM access into infrastructure that serves it again through…

BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
Scammers are abusing Meta’s copyright-reporting system to suspend people’s Instagram accounts and then hold them for ransom, according to the BBC. Criminals file fake copyright complaints with Instagram, claiming that an account is using material it doesn’t own. Repeated complaints can trigger a temporary account suspension from the platform, locking out the victim even though they haven’t done anything wrong. The criminal then moves the conversation to another platform, such as Telegram, and…

Executive Summary Since the release of our May 2026 report detailing adversarial misuse of artificial intelligence (AI), Google Threat Intelligence Group (GTIG) has observed forward leaning adversaries transition from basic prompting to agentic AI workflows and AI-enabled automation. In these operations, human-in-the-loop latency is dramatically reduced, compressing the traditional window for defenders to respond. In Q2 2026, GTIG observed threat actors compromise a cloud resource, then plan,…
Executive summary China-based artificial intelligence (AI) companies are conducting systematic extraction of proprietary functionalities and capabilities of U.S. AI companies’ models through industrial-scale knowledge distillation campaigns that form the core—not merely a supplement—of their AI development strategy. While “distillation” is recognized as a legitimate and useful technique in AI research, China-based AI companies are engaging in aggressive, malicious, and targeted distillation…
Cisco Talos began an investigation after observing a DLL named "verification.google" executing from WebDAV at a Ukrainian government organization. We assess with moderate confidence that the attacks are not targeted at a particular organization, but are a part of a cryptocurrency and credentials-stealing operation using the Amatera stealer as the primary payload. Pivoting around the similar WebDAV behavior led to a second loader named "pf.ch" and allowed us to reconstruct its earlier delivery…
Cisco Talos is tracking a cryptocurrency-stealing campaign that abuses the Google Visualization API for command and control (C2), retrieving obfuscated JavaScript from a publicly published Google Sheets document and injecting it into the victim's browser session. The actors use a variation on ClickFix social engineering. Instead of convincing targets to run commands against the operating system, they convince targets to paste JavaScript into the Chrome address bar or install it into the…
