Hackers Impersonate IT Support on Microsoft Teams to Take Control of Employee PCs
Microsoft warns of a human-operated campaign where attackers pose as IT support in Teams to gain remote PC control and reach domain controllers.
Microsoft Threat Intelligence observed attackers abusing Microsoft Teams external collaboration to impersonate IT/helpdesk staff, persuading employees to grant screen control via Quick Assist or RMM tools. Operators deploy malicious MSI packages via silent msiexec, run encrypted JavaScript implants through portable Node.js, and persist via EdgeUpdate Run keys or Startup folder entries. The Node.js backdoor uses HTTPS long-polling C2, captures screenshots, enumerates Active Directory, and moves laterally over WinRM (TCP 5985) to domain controllers and certificate authorities. Initial access maps to MITRE ATT&CK T1566.003 (Spearphishing via Service); no Teams vulnerability is exploited.

AnonyMousKIT phishing-as-a-service uses AI voice calls to steal iPhone passcodes
SOCRadar details AnonyMousKIT, an active phishing-as-a-service platform using AI voice agents across 506 domains to steal Apple ID credentials from stolen iPhone owners.
SOCRadar analyzed AnonyMousKIT, a pay-per-action phishing-as-a-service platform built to harvest Apple ID credentials needed to remove Activation Lock from stolen iPhones. A bare-relative-paths flaw exposed a reseller supply chain of 506 domains and 168 storefront brands active since early 2024, plus 200 call logs and 55 transcripts, with 179 of 200 calls going to Brazil at a total cost of $19.24. Voice-agent personas like 'Alice Dias, Apple Support' convince victims to dictate their four- or six-digit passcode and enter an unlock code from a security link, allowing thieves to remove Activation Lock and resell devices. The platform ran five personas in English, Spanish, and Brazilian Portuguese and remained active at the end of the investigation.
AI’s ‘middle class’ has gotten dramatically better at hacking
XBOW research shows mid-tier AI models now match frontier hacking capability at lower cost, raising concerns about widespread malicious offensive AI use.
XBOW benchmarks show mid-tier models such as Z.ai's GLM-5.2, xAI's Grok 4.5 and OpenAI's GPT-5.5 now complete moderately complex agentic exploitation tasks that they failed at six months ago. GPT-5.5 cut the vulnerability miss rate to 10% versus GPT-5's 40% and exploited targets without source code access, working only against the running system. Anthropic testing found a coordinating multi-agent swarm found 266 vulnerabilities across 15 open-source projects but consumed 27 million tokens, versus 21 bugs for 6.5 million tokens with non-coordinating agents. Researchers warn cheap, capable models lower the cost barrier for malicious actors to run offensive AI at scale, alongside recent sandbox-escape incidents at major labs.
AI Customer Service Bots Can Be Tricked Into Stealing Security Codes and Acting as Victims
DEF CON 34 research shows AI customer-service agents can be manipulated via prompt injection and email tricks to leak OTPs and act as victims.
Inti De Ceukelaire, presenting at Bug Bounty Village during DEF CON 34, demonstrated attacks against AI-powered customer service bots with access to customer profiles, billing data, support inboxes, and refund tools. Techniques include transcript-based phishing from trusted support addresses, From-header identity confusion, email normalization abuse to bypass OTP rate limits, and knowledge-base poisoning via RAG crawlers. He recommends separating untrusted content from system prompts, session-bound authentication, consistent email normalization, server-side tool validation, and least-privilege permissions for AI agents.
