AI Risk Guide: Assessing GenAI, Vendors and Threats

⚠️ This guide outlines the principal risks generative AI (GenAI) poses to organizations, categorizing concerns into internal projects, third‑party solutions and malicious external use. It urges inventories of AI use, application of risk and deployment frameworks (including ISO, NIST and emerging EU standards), and continuous vendor due diligence. Practical steps include governance, scoring, staff training, basic cyber hygiene and incident readiness to protect data and trust.

Social Engineering: How Attackers Exploit Human Weakness

🧠 Social engineering exploits human psychology to bypass technical and physical safeguards, using impersonation, deception and manipulation to gain access to systems, facilities or data. Attackers commonly use phishing, vishing, smishing, pretexting, baiting and tailgating after extensive reconnaissance to craft believable lures. High-value targets are often pursued via spear-phishing or BEC schemes, while opportunistic attackers rely on mass phishing. Practical defenses include ongoing security awareness training, verified procedures for urgent requests and realistic simulation tests; tools such as Social-Engineer Toolkit help organizations test their resilience.

China-aligned UTA0388 leverages AI in GOVERSHELL attacks

📧 Volexity has linked a series of spear-phishing campaigns from June to August 2025 to a China-aligned actor tracked as UTA0388. The group used tailored, rapport-building messages impersonating senior researchers and delivered archive files that contained a benign-looking executable alongside a hidden malicious DLL loaded via search order hijacking. The distributed malware family, labeled GOVERSHELL, evolved through five variants capable of remote command execution, data collection and persistence, shifting communications from simple shells to encrypted WebSocket and HTTPS channels. Linguistic oddities, mixed-language messages and bizarre file inclusions led researchers to conclude LLMs likely assisted in crafting emails and possibly code.

Phishing Campaign Uses Meta Business Suite to Target SMBs

📨 Check Point email security researchers uncovered a large-scale phishing campaign that abuses Meta's Business Suite and the facebookmail.com delivery domain to send convincing fake notifications. Attackers craft messages that appear to originate from Meta, allowing them to bypass many traditional security filters and increase the likelihood of SMBs across the U.S. and internationally engaging with malicious links or credential-stealing pages. Organizations should strengthen email defenses, monitor suspicious Business Suite activity, and educate staff to reduce exposure.

Identity Crisis at the Perimeter: AI-Driven Impersonation

🛡️ Organizations face an identity crisis as generative AI and vast troves of breached personal data enable realistic digital doppelgangers. Attackers now automate hyper-personalized phishing, smishing and vishing, clone voices, and run coordinated multi-channel campaigns that reference real colleagues and recent projects. The article urges a shift to “never trust, always verify,” with radical visibility, rapid detection and phishing-resistant authentication such as FIDO2. It also warns of emerging agentic AI and recommends strict least-privilege controls plus continuous red-teaming.

MuddyWater Exploits Compromised Mailboxes in Global Phishing

🔒 Researchers have uncovered a global phishing campaign that used compromised mailboxes to deliver malicious Microsoft Word attachments, attributed with high confidence to the Iran-linked actor MuddyWater by Group-IB. The operation abused a NordVPN-accessed mailbox to send trusted-looking messages that prompted users to enable macros, which then installed the Phoenix v4 backdoor. Investigators also found RMM tools (PDQ, Action1, ScreenConnect) and a Chromium_Stealer credential stealer, while infrastructure traced to the domain screenai[.]online and an IP tied to NameCheap-hosted services.

Reducing Abuse of Microsoft 365 Exchange Online Direct Send

🛡️ Cisco Talos warns that Microsoft 365 Exchange Online’s Direct Send feature, intended for legacy devices and line‑of‑business appliances, is being abused to bypass standard authentication and content inspection. Attackers are leveraging these unauthenticated SMTP flows in phishing and BEC campaigns by impersonating internal users and embedding obfuscated lures such as QR codes and empty‑body messages. Talos recommends a phased approach — inventorying dependencies, migrating devices to authenticated SMTP or partner connectors, and validating mailflows before enabling RejectDirectSend — to reduce risk without disrupting critical workflows.

Microsoft Tops Brand Phishing Impersonations in Q3 2025

🔍 Cyber criminals continue to favor familiar brands, with Microsoft used in 40% of all brand impersonation attempts in Q3 2025, according to Check Point Research’s Brand Phishing Report.

Universities Targeted in 'Payroll Pirate' Workday Hijacks

🔐 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.

Investigating Payroll Pirate Attacks on US Universities

🔍 Microsoft Threat Intelligence observed a financially motivated actor tracked as Storm-2657 conducting targeted 'payroll pirate' intrusions against US universities to divert salary payments. The actor used realistic phishing and adversary-in-the-middle (AiTM) links to harvest credentials and MFA codes, gained access to Exchange Online, abused SSO to reach Workday profiles, and created inbox rules to hide payroll notifications. Microsoft recommends adopting phishing-resistant, passwordless MFA and provides detections and remediation guidance.

Fraudulent Emails Imitating Airlines and Airports Sector

🛫 Kaspersky researchers uncovered a widespread email fraud campaign impersonating major airlines and airports to solicit advance refundable deposits. Attackers use convincing business-style messages, registration forms and NDAs rather than malware, then request several-thousand-dollar payments to secure partnership consideration. Recipients are urged to verify sender domains against official corporate contacts and treat any deposit request as a major red flag. Organizations should deploy strong email-gateway defenses and provide targeted security awareness training for finance, sales and procurement teams.

Solicitors urged to curb payment diversion fraud losses

🔒 The National Crime Agency and The Law Society have warned that UK house buyers faced average losses of £82,000 from payment diversion fraud over the past year. This form of payment diversion fraud (PDF) — a type of business email compromise — relies on hijacked or spoofed emails and lookalike domains to alter bank transfer instructions. The campaign urges solicitors and conveyancers to tighten checks and advises clients to verify bank details, use strong passwords, avoid public Wi‑Fi and transfer small initial amounts to confirm receipt.

Microsoft Warns of LLM-Crafted SVG Phishing Campaign

🛡️ Microsoft flagged a targeted phishing campaign that used AI-assisted code to hide malicious payloads inside SVG files. Attackers sent messages from a compromised business account, employing self-addressed emails with hidden BCC recipients and an SVG disguised as a PDF that executed embedded JavaScript to redirect users through a CAPTCHA to a fake login. Microsoft noted the SVG's verbose, business-analytics style — flagged by Security Copilot — as likely produced by an LLM. The activity was limited and blocked, but organizations should scrutinize scriptable image formats and unusual self-addressed messages.

New FileFix Variant Delivers StealC via Multilingual Phish

🔍 Acronis researchers warn of a campaign using a FileFix variant to deliver the StealC information stealer via a multilingual, heavily obfuscated phishing site. The lure mimics a Facebook security notice and hijacks the clipboard to implant a multi-stage PowerShell command that victims are tricked into executing through File Explorer. Attackers store encoded payload components as images on Bitbucket, decode them locally with a Go-based loader, and ultimately unpack shellcode that launches StealC. The infrastructure uses junk code, fragmentation and other anti-analysis techniques to evade detection and complicate forensic analysis.

VoidProxy Phishing Framework Bypasses MFA for SSO Logins

🔒 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.
