Infostealer Logs Expose Replayable AI Tokens That Can Bypass MFA

Okta finds infostealer logs contain thousands of replayable AI session tokens and API keys, letting criminals bypass MFA and access services from Google, Anthropic and OpenAI.

Okta analyzed a 7 GB infostealer dump from August 2, 2026 covering 5,871 infected machines in 162 countries and found 555 of 44,791 JWTs related to AI services, plus 1,843 unexpired JWTs and JWEs (largely set by OpenAI via NextAuth.js) and 24 still-valid API keys for Google Gemini, OpenAI, Groq and OpenRouter. Valid session tokens and API keys can be replayed with anti-detect browsers like Camoufox to bypass credential and MFA checks, fueling an underground market for AI account access known as LLMjacking, where attackers rack up victims' AI compute bills. Some 17.7% of the JWTs contained plaintext PII usable for social engineering. Google's GTIG reported growing buyer demand for Claude, Gemini, Cursor and Devin credentials, and Mandiant handled an incident where an actor used an exposed GitHub PAT to deploy unauthorized AI infrastructure and scale high-performance compute.

Slim Spider Steals Crypto Custody Secrets From Brazilian Financial Institution

CrowdStrike links previously unseen Slim Spider group to crypto custody secret theft at Brazilian financial institutions since March 2026.

CrowdStrike is tracking Slim Spider, a previously undocumented financially motivated group attacking Brazilian financial institutions since at least March 2026. The actor used custom Bash scripts to steal temporary cloud credentials, exfiltrated digital asset custody secrets, and used Foundry's cast tool to derive Ethereum wallet addresses, while deploying Go-based backdoor MikeDor and an implant impersonating Brazil's SPI instant payment infrastructure. Slim Spider also pivoted to Azure DevOps and Kubernetes clusters and used panels including NEXUS // Scanner, Painel de Emails Entra ID, and Painel Pix for reconnaissance and unauthorized Pix transfers. Separately, Google Threat Intelligence Group and Mandiant disclosed Breeze Comet (CL-CRI-1163), a Portuguese-speaking group since 2024 that breaches Brazilian payment infrastructure to run fraudulent Pix, Boleto, and STR transactions.

Threat actors are giving AI agents a bigger role in cyberattacks

Google Threat Intelligence's Q3 2026 tracker shows threat actors using AI agents for autonomous credential harvesting, including a six-hour campaign compromising thousands of credentials.

Google Threat Intelligence Group's Q3 2026 AI Threat Tracker, based on Mandiant incident response and platform telemetry, documents adversaries shifting toward AI-driven multi-step attack workflows. Mandiant investigated a financially motivated actor that compromised cloud infrastructure and used an AI coding chatbot plus agent instructions to run vulnerability scanning, troubleshooting, and IP rotation autonomously, harvesting thousands of third-party credentials in under six hours; an exposed 'Recon' C2 server held over 23,800 harvested secrets including cloud and AI API keys. Separately, two PRC-nexus espionage actors experimented with Gemini, Claude, and Codex to build automated penetration testing and exploitation frameworks, with Shai-Hulud used for C2 and credential harvesting. GTIG says no fully autonomous attack pipelines have yet been observed in the wild.

Mars Security brings threat intelligence to detection in real time

Mars Security launched Real-Time Intel-Based Detection, converting advisories from CISA and Mandiant into backtested MITRE ATT&CK-mapped detection rules for CrowdStrike, Wiz, and Splunk.

Mars Security announced a capability that automatically turns newly published threat intelligence from sources like CISA, Mandiant, Unit 42, and Microsoft into MITRE ATT&CK-mapped detection rules. Each rule is written in the native query language of the customer's telemetry (CrowdStrike Falcon, Wiz, Splunk, firewalls, identity providers, AWS, Snowflake, Databricks) and backtested against 30 days of the customer's data before deployment, with indicator scoring to drop noisy or stale indicators. The platform also maps existing detection coverage, flags gaps such as AWS CloudTrail tampering and pass-the-hash movement, and delivers some recommendations as open pull requests for detection-as-code workflows.

Fake IT Calls Target Executives in Microsoft 365 Data Theft and Extortion Attacks

Arctic Wolf tracks PREY-0058, a vishing and AitM token-theft crew targeting Microsoft 365 executives for data theft and extortion.

Arctic Wolf disclosed a widespread data theft and extortion cluster, PREY-0058, which overlaps with Mandiant's UNC6671 and possibly the Pink/Cinder extortion groups. Attackers impersonate IT help desk staff by phone, direct executives to authentication-themed lure domains, and run adversary-in-the-middle Microsoft 365 logins to harvest credentials, MFA approvals, and session tokens replayed via residential proxies such as NodeMaven. After access, they run discovery in SharePoint and Entra ID, then bulk-exfiltrate data from SharePoint, OneDrive, Exchange, and Box before sending extortion demands. Targets are primarily US construction, healthcare, real estate, finance, and professional services organizations.

UNC6671 Vishing Attacks Target Personal Phones to Steal SaaS Data

Google and Mandiant attribute vishing-based SaaS data extortion attacks to UNC6671, now operating under the Redact, Pink, Helix, and Falcon brands.

Google Threat Intelligence Group and Mandiant track extortion group UNC6671, which uses vishing calls impersonating IT help desks to lure employees to adversary-in-the-middle phishing pages that capture credentials, MFA tokens, and session tokens. The group then registers adversary-controlled MFA devices, pivots through identity providers into Microsoft 365, Okta, and other SaaS applications, and runs automated Python and PowerShell exfiltration scripts. UNC6671 has rotated through extortion brands including BlackFile, Redact, Pink, Helix, and Falcon, and Google tracked over $10.6 million in Bitcoin payments between January 7 and May 12, 2026, with initial demands exceeding $3 million. The actor has hit dozens of organizations in North America, Australia, and the UK, shifting toward high-value financial and legal firms in July 2026.

New Ted Backdoor Hides Inside Victims' Own HAProxy Builds to Intercept Web Traffic

Rapid7 found a new backdoor, ted, compiled into trojanized HAProxy at two South Korean organizations, with medium-confidence attribution to North Korean actors.

Rapid7 documented a previously undocumented Linux toolkit named ted compiled into the HAProxy load balancer binaries of two South Korean organizations in the automotive and media sectors. The implant intercepts web traffic, serves altered pages only to filtered visitors, and hides C2 exchanges from backend logs and HAProxy statistics; a companion RAT, curlRAT, beacons on a default 12-hour schedule. The toolkit also trojanizes crond, sshd, agetty, atd, and polkitd binaries and sanitizes logs and bash history. Rapid7 attributes the activity with medium confidence to North Korean state-sponsored actors, with domain infrastructure overlapping APT37 listings in maltrail and delivery resembling the Operation SyncHole campaign.

Details emerge on BlackFile's recent attacks on financial companies

BlackFile (UNC6671), a The Com-linked extortion crew, keeps hitting financial and med tech firms with voice-phishing IT-support scams and ~$3 million demands.

Google Threat Intelligence Group (tracking BlackFile as UNC6671, linked to The Com) reports the extortion group remains active, shifting focus to the financial sector and med tech organizations, with new Redact-brand extortion demands issued last week. The group impersonates IT support in voice-phishing attacks using hundreds of recruited callers, targets large firms in what researchers call big-game hunting, and processes an average of 1.5 new victims daily. Extortion demands start around $3 million and are typically negotiated below $1 million; Flashpoint observed infrastructure targeting Blackstone, Bain Capital, Moody's, CME, and Apollo, though compromise is unconfirmed. Mandiant has responded to more than two dozen BlackFile compromises since January, and victims face escalation tactics including swatting.

Brand Impersonation Takedown: From Whack-a-Mole to Managed Response

Mandiant-tracked group UNC3753 impersonated US professional services firms' brands in 2026; Cyble urges managed takedowns over manual abuse reports.

Cyble describes how Google Mandiant-tracked group UNC3753 targeted US professional services firms between January and May 2026 using brand impersonation, spoofed domains, and fake executive profiles. Manual takedowns fail because phishing pages damage brands within hours while removal takes days. A managed takedown program with continuous monitoring and pre-authorized removal cuts the exposure window from days to hours.
