Mapping out your unknown: A threat hunter’s guide to GitHub

Datadog Security Labs publishes a threat-hunting guide with audit-log queries to detect GitHub token theft, device code phishing, and source code exfiltration.

Datadog's threat-hunting guide covers GitHub audit log queries for detecting compromised accounts, stolen personal access tokens, and malicious OAuth app authorizations. Attackers typically obtain credentials through phishing, credential stuffing, leaked secrets, or device code phishing, then map private repositories, exfiltrate source code, and pivot into connected cloud and CI/CD environments. The guide maps detections to MITRE techniques like T1078 and T1528 and documents GitHub logging quirks affecting attribution, token metadata, and visibility fields.

The Top 4 Threats We Found by Investigating Every Alert for a Quarter

Prophet Security's quarterly threat report finds identity attacks made up roughly half of confirmed malicious activity, with stolen authenticated sessions bypassing conditional access controls.

Between May 1 and July 31, 2026, Prophet Security investigated every alert in customer environments immediately on arrival; about 7% of completed investigations were confirmed malicious. Direct account/session attacks made up roughly 18% of confirmed activity, with replayed authenticated sessions bypassing conditional access since no re-authentication occurs. Infostealer activity affected about a quarter of investigated organizations, mostly delivered via browsers through compromised websites, malicious ads, sponsored search results and ClickFix fake CAPTCHA gates, with payloads including Lumma Stealer, Vidar, HijackLoader and AsyncRAT. Credential phishing was the largest category at about 28%, with adversary-in-the-middle relays revealed by seconds-long MFA approvals from distant countries and MFA fatigue attacks exploiting automatic unlock policies.

U.S. Sanctions Iran-Linked Hackers Behind Critical Infrastructure Breaches

U.S. Treasury sanctioned nearly 60 Iran-linked entities, including MOIS-affiliated Mabna Institute hackers behind breaches of U.S. critical infrastructure and millions in crypto theft.

The U.S. Treasury launched Operation Economic Outcast, designating nearly 60 Iran-linked entities, individuals, and vessels across nuclear, missile, oil, cyber, and digital asset networks. Five sanctioned individuals are members of the Tehran-based Mabna Institute indicted last week; three allegedly breached and exfiltrated data from U.S. energy, defense, healthcare, IT, and financial organizations since late 2023. TRM Labs traced roughly $16.8 million across 30 wallets tied to the members, and the State Department announced a reward of up to $10 million. The action follows Iranian hacking of FBI Director Kash Patel's email and attacks on over 30 U.S. water and wastewater utilities.
