### The Rise of Invisible Unicode Characters in Phishing Campaigns
One of the more insidious phishing tactics to surface involves the use of invisible Unicode tag characters. These are non-printing symbols that can be embedded within text without being visible to the human eye. According to recent disclosures, attackers have been leveraging these characters to bypass machine learning and natural language processing filters used by email security platforms.
The technique, sometimes referred to as ASCII Smuggling, was deployed in a campaign spanning from early February through late June. Financial terms such as “funding” were altered with hidden Unicode characters, allowing the malicious content to slip through spam and phishing detection systems unnoticed. During the campaign’s peak, as many as 2.37 million messages per day were generated, putting enormous strain on automated filtering systems. The volume and sophistication of this campaign demonstrate how attackers are continuously adapting to evade modern email defenses.

### FBI Warns About OAuth Consent Phishing Attacks
The Federal Bureau of Investigation has issued a warning about a phishing technique that uses OAuth consent prompts to gain unauthorized access to user accounts. Unlike traditional phishing, which relies on stealing passwords, consent phishing tricks users into granting permissions to malicious applications that appear legitimate.
In these attacks, threat actors impersonate trusted individuals or organizations and direct victims to malicious applications. Once the user grants the requested permissions — which can look entirely legitimate — the attacker gains persistent access to the victim’s email, files, calendar, contacts, and other sensitive data. Because no password is stolen in the process, many traditional authentication defenses are bypassed entirely.

### Deep Connections Found Between Chinese Hacking Group and Military Contractors
New research from Natto Thoughts has shed light on the extensive ties between the China-based hacking group QTFY and several organizations linked to China’s military and intelligence apparatus. Building on a joint advisory from U.S. and allied agencies, the analysis connects QTFY to Nanjing Xinjiuwei Network Technology Co. and highlights two affiliated entities — ELEX and Nanjing Lexbell Information Technology.
ELEX’s historical client lists reportedly included entities connected to China’s Ministry of State Security, the Ministry of Public Security, and the People’s Liberation Army. Meanwhile, Lexbell has been linked to military-focused products, leadership with PLA affiliations, and contracts with the National University of Defense Technology. These findings underscore the deep integration between Chinese state-linked cyber operations and the country’s defense industrial base.

### Former AT&T Employee Sentenced for SIM Swapping Fraud
Kenneth Carter, a former employee of AT&T, has been sentenced to 16 months in federal prison for his role in a SIM swapping scheme. Carter used his insider access to the telecommunications network to facilitate fraudulent SIM swaps, enabling criminals to take over victims’ bank accounts.
The scheme targeted at least three victims who suffered intended losses totaling nearly $600,000. Carter reportedly received between $1,000 and $2,000 for each fraudulent SIM swap he facilitated. The case highlights the serious insider threat that telecommunications employees can pose and the need for robust access controls and monitoring within sensitive industries.

### Russian National Extradited and Charged Over Cybercrime Infrastructure
Sergei Anatolyevich Filimonov, a Russian national, was extradited from Georgia and formally arraigned in the United States on charges related to running a cybercrime infrastructure operation. Prosecutors allege that Filimonov was involved in a credential-harvesting and bank fraud scheme that specifically targeted U.S. banking customers.
The operation reportedly used fake financial websites and sponsored search results to direct victims to phishing sites. The infrastructure maintained by Filimonov allegedly stored more than 5,000 stolen credentials and was used in attempts to steal millions of dollars. His extradition and prosecution represent a significant step in international efforts to hold cybercriminals accountable across borders.

### Researchers Demonstrate InjectEave: A New Class of Electromagnetic Side-Channel Attack
Security researchers have introduced InjectEave, a novel class of electromagnetic side-channel attack that exploits hardware nonlinearities to extract sensitive information from devices. By directing an external radio frequency signal at a target device, attackers can induce subtle hardware behaviors that leak low-frequency analog data.
Tests conducted on 11 commercially available devices — including headphones, VoIP phones, smart fans, and smart lamps — demonstrated that attackers could recover private audio or determine the operational states of appliances, all without needing physical access to the devices or making any modifications. The findings raise significant concerns about the security of Internet of Things (IoT) devices in both consumer and enterprise environments.

### Project Glasswing Reality Check Reveals Gaps in AI-Driven Vulnerability Reporting
VulnCheck has conducted an independent review of Anthropic’s Project Glasswing ledger and the results paint a sobering picture of the gap between AI-generated vulnerability assessments and real-world remediation. Of the 26,153 findings that were reportedly submitted through the project, only 202 had been fixed after nearly five months. Additionally, 245 findings were withdrawn entirely.
Perhaps most revealing is the disparity in severity ratings: Claude, Anthropic’s AI model, rated 91.5% of findings that had available ratings as high or critical severity. In contrast, the actual software maintainers rated only 51.3% of those same findings as high or critical. This significant mismatch suggests that AI-driven vulnerability discovery tools may overstate the urgency and severity of reported issues, raising questions about how organizations should prioritize and triage AI-generated security findings.

## Frequently Asked Questions (FAQ)
**What is Unicode tag character phishing?**
Unicode tag characters are invisible, non-printing symbols that can be inserted into text to alter how it is processed by security filters. Attackers use these characters to modify words in phishing emails so that they bypass machine learning and natural language processing detection systems while remaining undetectable to human readers.
**How can website owners protect against the WordPress Super Forms vulnerability?**
Website owners should immediately update their WordPress Super Forms plugin to version 6.3.314 or later. Since the vulnerability allows unauthenticated file uploads, it is also recommended to review file upload permissions, implement web application firewalls, and regularly monitor for unauthorized file changes on the server.
**What is OAuth consent phishing, and how is it different from regular phishing?**
OAuth consent phishing does not rely on tricking users into entering their passwords. Instead, attackers trick users into granting permissions to malicious applications through legitimate-looking OAuth consent screens. Once permissions are granted, the attacker can access the victim’s email, files, and other data directly through the authorized application, bypassing password-based defenses.
**Why are electromagnetic side-channel attacks like InjectEave concerning?**
These attacks are concerning because they can extract sensitive information — such as audio or device state — from electronic devices without requiring physical access or any software installation on the target device. This makes traditional endpoint security measures ineffective against them, especially for IoT devices that lack built-in protections against RF-based attacks.
**What does the Glasswing review tell us about AI in vulnerability discovery?**
The review highlights a significant gap between the severity ratings assigned by AI systems and those assessed by human maintainers. This suggests that while AI can be a powerful tool for identifying potential vulnerabilities, the results still require careful human validation and prioritization to avoid misallocating resources toward false positives or overblown severity assessments.
