China-linked APT41 Targets U.S. Trade Policy Networks

🔒 The House Select Committee on China warned of an ongoing series of targeted cyber-espionage campaigns tied to the PRC that aim at organizations involved in U.S.–China trade talks. Attackers impersonated Rep. John Robert Moolenaar in phishing emails that delivered malware via attachments and links, abusing cloud services and software to conceal activity. The campaign, attributed to APT41, affected trade groups, law firms, think tanks, U.S. government agencies and at least one foreign government.

Axios Abuse and Salty 2FA Kits Fuel Direct Send Phishing

🔒 ReliaQuest reports threat actors increasingly abusing the HTTP client Axios alongside Microsoft's Direct Send to create a highly efficient phishing pipeline that intercepts and replays authentication flows. Campaigns beginning in July 2025 targeted executives in finance, healthcare, and manufacturing and expanded to all users, achieving up to a 70% success rate when pairing Axios with Direct Send. Attackers also use PDF lures with malicious QR codes, Google Firebase hosting, and advanced MFA-bypass kits such as Salty2FA to simulate multiple 2FA methods and steal credentials.

Salty2FA Phishing Kit Undermines Confidence in MFA

🔐 A newly uncovered phishing campaign uses the Salty2FA phishing‑as‑a‑service kit to bypass multi‑factor authentication by intercepting verification methods, rotating unique subdomains and hiding behind Cloudflare Turnstile gates that filter automated analysis. Ontinue found the kit simulates SMS, authenticator apps, push prompts and hardware tokens while dynamically applying corporate branding to match victims' email domains. Industry experts characterize this as a more mature, evasive form of phishing and recommend phishing‑resistant authentication, runtime inspection and continuous user training.

New Malware Campaigns: MostereRAT and ClickFix Risks

🔒 Researchers disclosed linked phishing campaigns delivering a banking malware-turned-RAT called MostereRAT and a ClickFix-style chain distributing MetaStealer. Attackers use an obscure Easy Programming Language (EPL), mutual TLS for C2, and techniques to disable Windows security and run as TrustedInstaller to evade detection. One campaign drops remote-access tools like AnyDesk and VNC variants; another uses fake Cloudflare Turnstile pages, LNK tricks, and a prompt overdose method to manipulate AI summarizers.

iCloud Calendar abused to send phishing via Apple Servers

📅 iCloud Calendar invites are being abused to send callback phishing emails that appear to originate from Apple's servers and pass SPF, DKIM, and DMARC checks. Attackers embed phishing content in the event Notes and invite a Microsoft 365 forwarding address so the message is relayed to targets while Apple remains the visible sender. Treat unexpected calendar invites with unusual messages or requests cautiously; calling listed numbers or granting remote access can lead to fraud, malware, or data theft.

VirusTotal Uncovers SVG-based Judicial Portal Phishing

🔍 VirusTotal's AI Code Insight detected a sophisticated phishing campaign that hid malicious JavaScript inside SVG images to impersonate Colombia's judicial system. The SVGs rendered fake portal pages with a bogus download progress bar and displayed a password for a protected ZIP archive that contained malware artifacts. The archive included a renamed Comodo Dragon executable, a malicious DLL, and two encrypted files; when the executable runs the DLL is sideloaded to install further malware. After adding SVG support, VirusTotal found 523 related SVGs that had evaded traditional antivirus detection.

Noisy Bear Targets Kazakhstan Energy Firm with Phishing

🚨 Operation BarrelFire, attributed to a group Seqrite Labs calls Noisy Bear, targeted Kazakhstan's national oil company KazMunaiGas in May 2025 using tailored phishing. Attackers sent ZIP attachments containing an .LNK downloader, a decoy document, and a README in Russian and Kazakh instructing use of a fake KazMunayGaz_Viewer. The chain deployed a malicious batch, a PowerShell loader named DOWNSHELL, and a 64-bit DLL implant that executes shellcode to open a reverse shell. Infrastructure was linked to Russia-based bulletproof host Aeza Group, which has been sanctioned.

Sharp Rise in Cyberattacks on German Education Sector

🔒 Researchers at Check Point report a 56% year-over-year increase in cyberattacks against German educational institutions as the new school year begins, well above the global average. Analysts observed targeted phishing campaigns, including an August 2025 scheme that redirected victims to fake university and Outlook login pages to harvest credentials. To mitigate risk, experts recommend targeted phishing awareness training, mandatory multi-factor authentication (MFA), early detection of suspicious domains, regular system updates and deployment of modern threat-prevention solutions as part of a preventive, multi-layered security strategy.

Six Browser-Based Attack Techniques to Watch in 2025

🔒 This article outlines six browser-based attack techniques—phishing with reverse-proxy AitM kits, ClickFix/FileFix command-injection lures, malicious OAuth grants, rogue extensions, weaponized file downloads, and credential attacks exploiting MFA gaps—that security teams must prioritize in 2025. It explains why the browser has become the primary attack surface as users access hundreds of cloud apps, and why traditional email/network controls and endpoint defenses often miss these threats. The piece argues that effective detection requires real-time browser-level visibility and management across managed and unmanaged apps, highlighting Push Security as a vendor offering such capabilities.

SVG Malware Campaign Impersonating Colombian Judiciary

🔍 VirusTotal’s Code Insight now parses SWF and SVG formats and quickly uncovered an undetected campaign impersonating the Colombian justice system. The tool differentiated a benign, heuristic-flagged SWF game from a malicious SVG that evaded all AV engines by hiding inline JavaScript which decodes and injects a Base64 phishing page and a ZIP dropper. Code Insight plus VirusTotal Intelligence exposed dozens of polymorphic SVGs and enabled a retrohunt linking hundreds of samples to the same campaign.

Tycoon Phishing Kit Uses New Link Obfuscation Techniques

🔐 Barracuda researchers have detailed new link-obfuscation capabilities in the Tycoon Phishing-as-a-Service kit that hide malicious destinations from scanners and recipients. Observed techniques include URL encoding with '%20' invisible spaces, deceptive Unicode characters, hidden codes appended to links, redundant protocol prefixes, and subdomain manipulation. Attacks also incorporate a fake CAPTCHA stage and tools aimed at bypassing multi-factor authentication, enabling more effective email-based social engineering and evasion of traditional filters.

Iran-linked Spear-Phishing Targets 100+ Embassies Worldwide

📧 Israeli cybersecurity company Dream has attributed a coordinated, multi-wave spear-phishing campaign to Iranian-aligned operators connected to Homeland Justice, targeting embassies, consulates, and international organizations globally. Attackers used geopolitical lures and 104 unique compromised sender addresses — including a hacked mailbox at the Oman Ministry of Foreign Affairs in Paris — to distribute Microsoft Word documents that prompt users to Enable Content and run embedded VBA macros. The macros drop executables that establish persistence, contact command-and-control servers, and harvest system information; ClearSky has also documented related activity and linked it to prior Iranian techniques.

When Browsers Become the Attack Surface: Rethinking Security

🔒 As enterprises shift more critical work to the browser, adversary Scattered Spider (UNC3944) targets live browser data—saved credentials, calendars, and session tokens—to achieve account takeover and persistent access. The article highlights techniques like Browser-in-the-Browser overlays, JavaScript injection, malicious extensions, and token theft that evade conventional EDR. It recommends elevating browser-native controls: runtime JavaScript protection, session-token binding, extension governance, API restrictions, and integrated browser telemetry so CISOs treat browser security as a primary defense layer.

ScarCruft Deploys RokRAT in 'HanKook Phantom' Campaign

🚨Seqrite Labs has uncovered a spear-phishing campaign named Operation HanKook Phantom attributed to North Korea–linked ScarCruft (APT37). The attacks use ZIP attachments containing malicious Windows LNK shortcuts that masquerade as PDFs and drop a RokRAT backdoor while displaying decoy documents. RokRAT can collect system information, execute commands, enumerate files, capture screenshots, and download further payloads, exfiltrating data via cloud services such as Dropbox, Google Cloud, pCloud, and Yandex Cloud. A second observed variant leverages fileless PowerShell and obfuscated batch scripts to deploy additional droppers and conceal network traffic as browser file uploads.

Cloudy-driven Email Detection Summaries and Guardrails

🛡️Cloudflare extended its AI agent Cloudy to generate clear, concise explanations for email security detections so SOC teams can understand why messages are blocked. Early LLM implementations produced dangerous hallucinations when asked to interpret complex, multi-model signals, so Cloudflare implemented a Retrieval-Augmented Generation approach and enriched contextual prompts to ground outputs. Testing shows these guardrails yield more reliable summaries, and a controlled beta will validate performance before wider rollout.

115,000 Phishing Emails Leveraged Google Classroom

⚠ Check Point uncovered a global phishing campaign that delivered 115,000 fake invitations via Google Classroom to about 13,500 organizations worldwide within a single week. Attackers used seemingly legitimate classroom invites to present unrelated commercial offers and instructed recipients to continue contact via WhatsApp, shifting conversations off monitored email channels. Because many filters treat messages from Google services as trustworthy, these messages often bypass conventional protections. Experts advise staff training, adoption of AI-driven detection that evaluates context and intent, and extending phishing defenses beyond email to collaboration and messaging platforms.

Blind Eagle: Five Clusters Target Colombian Government

⚠️ Recorded Future's Insikt Group attributes five distinct activity clusters to the actor Blind Eagle (tracked as TAG-144) active between May 2024 and July 2025. The campaigns largely targeted Colombian government agencies across local, municipal, and federal levels using spear-phishing, cracked and open-source RATs (including AsyncRAT, Remcos, DCRat, and Lime RAT) and legitimate internet services for staging. Operators abused dynamic DNS, VPS and VPN services and leveraged geofencing and compromised accounts to redirect or evade detection.

Phishing Campaign Uses UpCrypter to Deploy Multiple RATs

🔒 FortiGuard Labs has detailed a global phishing campaign that uses personalized HTML attachments and spoofed websites to deliver a custom loader, UpCrypter, which installs multiple remote access tools. The operation uses tailored lures—voicemail notices and purchase orders—embedding recipient emails and company logos to appear legitimate. The delivered ZIPs contain obfuscated JavaScript that runs PowerShell, fetches further payloads (sometimes hidden via steganography) and ultimately loads RATs such as PureHVNC, DCRat and Babylon, while UpCrypter checks for sandboxes, enforces persistence and can force reboots to hinder analysis.

ZipLine: Advanced Social Engineering Against U.S. Industry

🔒 ZipLine is a highly sophisticated social-engineering phishing campaign identified by Check Point Research that reverses the typical attack flow by initiating contact through corporate “Contact Us” forms. Attackers cultivate multi-week, professional email exchanges and often request NDAs before delivering a malicious ZIP containing the in-memory backdoor MixShell. MixShell maintains covert command-and-control via DNS tunneling with HTTP fallback and executes in memory to reduce forensic traces. The campaign primarily targets U.S. manufacturing and supply-chain–critical organizations and has evolved a second wave that uses an AI transformation pretext to increase legitimacy.

Phishing Campaign Uses UpCrypter to Deploy RATs Globally

📧 Fortinet FortiGuard Labs has observed a phishing campaign using fake voicemail and purchase-order lures to direct victims to convincing landing pages that prompt downloads of JavaScript droppers. The droppers retrieve the UpCrypter loader, which conducts anti-analysis and sandbox checks before fetching final payloads, including various RATs such as PureHVNC, DCRat and Babylon. Attacks since August 2025 have targeted manufacturing, technology, healthcare, construction and retail/hospitality across multiple countries; defenders are urged to block malicious URLs, strengthen email authentication, and monitor anomalous M365 activity.
