🔐 Microsoft says the Storm-2657 gang has been targeting U.S. university HR employees since March 2025 in “payroll pirate” attacks that aim to hijack salary payments by compromising Workday accounts and Exchange Online mailboxes. Attackers use tailored phishing themes—campus illness, faculty misconduct, executive impersonation—and adversary‑in‑the‑middle (AITM) links to steal MFA codes and gain access. They then set inbox rules to hide warnings, adjust payroll SSO settings, and sometimes enroll attacker phone numbers as MFA devices; Microsoft urges deployment of phishing‑resistant MFA and offers investigative guidance.

🧑‍💻 Threat actors claiming to represent Medusa contacted BBC cybersecurity correspondent Joe Tidy via Signal in July, offering him a cut of any ransom in exchange for providing access to BBC systems. They initially offered 15% of the paid ransom, later adding an extra 10% and even proposing 0.5 BTC placed in escrow. When Tidy hesitated, the actors launched MFA bombing attempts; he alerted the BBC security team and was disconnected from corporate systems as a precaution.

🔐Akira ransomware operators are successfully authenticating to SonicWall SSL VPN accounts even when one-time password (OTP) multi-factor authentication is enabled. Arctic Wolf links the logins to credentials and OTP seeds harvested via an improper access control flaw tracked as CVE-2024-40766, and notes attackers can reuse those secrets after devices are patched. Once inside, actors rapidly scan internal networks, harvest backup server credentials, and use techniques such as BYOVD to sideload vulnerable drivers and disable protections. Administrators are urged to install the latest SonicOS (recommended 7.3.0) and reset all SSL VPN credentials immediately.

🔐 Organizations should urgently update defenses to counter the Scattered Spider collective, experts warned at the Gartner Security & Risk Management Summit 2025. The group used social engineering, helpdesk vishing, and push notification fatigue to bypass MFA and abuse SSO, compromising accounts like Okta and stealing tokens from LastPass. Firms are advised to implement stronger identity protections, number-matching MFA, stricter password-reset procedures, and tighter third-party vendor monitoring to reduce exposure.

🔒 Okta threat researchers have identified a Phishing-as-a-Service called VoidProxy that leverages Adversary-in-the-Middle techniques to capture usernames, passwords, MFA codes and session cookies from Microsoft, Google and several SSO providers. The service uses compromised email service provider accounts, URL shorteners, Cloudflare Workers and disposable domains to evade detection and takedown. Victim credentials and session tokens are proxied to legitimate services, allowing attackers to reuse valid session cookies. Okta warns legacy methods such as SMS and OTP are especially vulnerable to this attack.

🔒 Rapid7 and SonicWall report a surge in intrusions tied to the Akira ransomware group exploiting a year-old SSL VPN vulnerability, CVE-2024-40766 (CVSS 9.3), and LDAP misconfigurations that retained local passwords during migrations. Attackers are brute-forcing credentials, abusing SonicWall's Virtual Office defaults to enable mMFA/TOTP, and using loaders like Bumblebee to deploy AdaptixC2 and persistent tools. SonicWall urges rotating local accounts, enabling Botnet Filtering and Account Lockout, enforcing MFA, restricting Virtual Office access, and reviewing LDAP default groups.

🔒 A newly identified phishing-as-a-service called Salty2FA is being used in campaigns that bypass multi-factor authentication by intercepting verification flows and abusing trusted services like Cloudflare Turnstile. Ontinue researchers report the kit uses subdomain rotation, domain-pairing, geo-blocking and dynamic corporate branding to make credential pages appear legitimate. The framework simulates SMS, authenticator apps, push approvals and even hardware-token prompts, routing victims through Turnstile gates to filter automated analysis before harvesting credentials.

⚠️ Researchers at ANY.RUN have uncovered Salty2FA, a new phishing-as-a-service kit engineered to harvest credentials and bypass multiple two-factor authentication methods. First observed gaining momentum in mid-2025, the kit uses multi-stage redirects, Cloudflare checks and evasive hosting to slip past automated filters. Salty2FA intercepts push, SMS and voice codes, enabling account takeover across finance, energy and telecom sectors.

🔒 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.

⚠️ Researchers have exposed a Salty2FA phishing kit that applies enterprise-grade tactics to harvest credentials and bypass detection. The campaign uses session-based subdomain rotation, abuse of legitimate platforms for staging, and corporate-branded login replicas to increase believability. Operators integrate Cloudflare Turnstile and obfuscated, XOR-encrypted JavaScript to block automated analysis and frustrate forensic inspection. Targets include healthcare, finance, technology, energy and automotive sectors, underscoring the need for updated defenses beyond traditional indicators.

🔐 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.

🔒 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.

🔐 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.

🔒 Falcon Next-Gen SIEM provides real-time, cross-domain detection to help organizations detect and respond to the identity-centric eCrime group SCATTERED SPIDER. The platform correlates identity, cloud, SaaS, network and email telemetry, offering out-of-the-box rule templates for phishing, MFA fatigue, suspicious SSO events and exfiltration. CrowdStrike recommends comprehensive log ingestion and tuning of these templates to improve detection and response across the full attack lifecycle.
