Attacker Hijacks AI Coding Assistant Session, Spreads Shai-Hulud Across About 100 Repositories

Mandiant says an attacker hijacked an AI coding-assistant session at a SaaS provider and spread the Shai-Hulud worm across roughly 100 repositories, stealing secrets.

Mandiant's September 2026 report describes an attacker hijacking an active AI coding-assistant session at an unnamed SaaS provider, then getting a poisoned package recommendation accepted and installing an infostealer via a malicious PyPI package. The attacker stole GitHub OAuth tokens, deployed the self-spreading Shai-Hulud worm across approximately 100 internal repositories, and stole repository secrets and product source code. Poisoning a package in the company's official namespace caused a second employee to pull the compromised version and become infected. Mandiant recommends verifying AI-recommended dependencies against checksums and allowlists, keeping secrets out of extension reach, and routing dependency traffic through internal repositories.

3BB Attacker Used MeshCentral Backdoor for Root Access, Targeted Subscriber Credentials

Hunt.io found an attacker holding root access inside Thai ISP 3BB via a MeshCentral backdoor, targeting subscriber RADIUS credential databases.

Hunt.io discovered an exposed attacker server on June 3, 2026 revealing an ongoing intrusion at 3BB, one of Thailand's largest broadband providers. The attacker maintained hidden MeshCentral agents reporting to www.ayuthayatech[.]com (device group TH-3BB) and held root on internal servers. Recovered scripts sprayed passwords over SSH against more than 55 internal machines, planted web shells, added SSH keys, searched for stored credentials, and targeted RADIUS subscriber credential databases, though exfiltration was not confirmed. The toolkit included a full exploit for FortiGate SSL-VPN flaw CVE-2024-21762 against mail.3bb.co[.]th, but the initial access vector is unestablished, and a cleanup script erased logs while preserving the backdoor.

Attackers Breached JetBrains Cadence via Unpatched TeamCity, Extracting AWS Credentials

Unknown attackers exploited critical TeamCity flaw CVE-2026-63077 to breach JetBrains Cadence, stealing a 2024 backup, user data, and AWS credentials; rotation urged.

JetBrains disclosed that threat actors exploited CVE-2026-63077 (CVSS 9.8), a TeamCity deserialization vulnerability added to CISA's KEV catalog on August 5, 2026, to breach its Cadence cloud computing service, with the intrusion running August 8-24, 2026. Confirmed access includes personal data (usernames, names, emails, login timestamps, IPs), a full 2024 Cadence server backup containing credentials and configuration, multiple AWS IAM users and secrets, files in JetBrains S3 buckets, and possibly PyCharm-synchronized source code. The compromised api.cadence.jetbrains.com server has been taken offline and all Cadence plugin access tokens invalidated. JetBrains urges users to immediately revoke or rotate all credentials used with Cadence and treat all executions, inputs, and outputs as potentially untrusted.

Trezor Says ShipMonk Breach Exposed 67,000 U.S. Customers' Data It Said Was Deleted

Trezor disclosed the ShipMonk breach exposed data of 67,000 additional US customers, reportedly by ShinyHunters exploiting a Metabase zero-day SQL injection, CVE-2026-72898.

Trezor disclosed that a breach at shipping provider ShipMonk exposed names, email addresses, phone numbers, shipping addresses, and order numbers of 67,000 additional US customers, with orders dating November 2019 to August 2021 despite written assurances the data had been deleted. This adds to the 13,689 customers previously disclosed after ShipMonk informed Trezor of unauthorized access on August 10, 2026. According to Holborn, the ShinyHunters extortion gang is behind the breach, which began with zero-day exploitation of CVE-2026-72898 (CVSS 10.0), a critical SQL injection flaw in Metaboobase analytics software Metabase. Trezor says hardware wallet security is unaffected but warns customers to watch for phishing and social engineering; ShipMonk has not publicly acknowledged the incident.

Thomson Reuters Court Software Breach May Have Exposed SSNs and Sealed Data

Unauthorized access to Thomson Reuters' C-Track court platform may have exposed SSNs and sealed records across 11 US states, USVI, and Ontario.

Thomson Reuters' West Publishing disclosed that an unauthorized party obtained files from the C-Track court case management platform starting in March 2026, with access to one environment running from March 1 through June 29, 2026 per Montana's account. Notices name roughly 24 court bodies across 11 US states, the US Virgin Islands, and Ontario, including appellate courts in Minnesota, Ohio, Montana, and Pennsylvania. Exposed data may include names, Social Security numbers, driver's license numbers, dates of birth, medical and health insurance information, and confidential or sealed court records. The company is offering 12 months of Experian or TransUnion monitoring, and courts disagree over whether the vendor's backup cloud environment or the production platform was accessed.

Attackers Steal METR API Key and Consume AI Credits Worth About $600,000

METR disclosed attackers stole an API key and burned about $600,000 in inference credits, plus a second probing campaign against its infrastructure.

METR, the AI model evaluation non-profit, disclosed two 2026 security incidents. In March, attackers found a publicly exposed EC2 instance behind a fail-open authentication bug, prompted an agent to reveal its API key, added SSH persistence, and consumed roughly $600,000 in inference credits over three weeks. In May, a likely financially motivated actor systematically probed METR's public infrastructure using agents for vulnerability discovery, credential stuffing, OAuth token grants and staff phishing, with no confirmed access to non-public data.

SafePal Hardware Wallet Maker Says Flaw Exposed Data of Nearly 40,000 Customers

SafePal disclosed an order-tracking plug-in authorization flaw exposing names, emails, addresses and purchase details of 39,798 hardware wallet customers; no wallet credentials affected.

Hardware wallet maker SafePal disclosed that an authorization flaw in an order-tracking plug-in exposed names, email addresses, shipping addresses, phone numbers and purchase details of approximately 39,798 customers. No seed phrases, private keys, wallet credentials or financial information were exposed, and SafePal found no evidence of wallet or fund compromise. A separate configuration error left a data-cleanup process broken between September 2025 and April 2026, extending the affected order window back to March 2025. A threat actor has advertised a matching dataset on a cybercrime forum, and the company has fixed the flaw, cut data retention to 90 days, purged affected records, engaged third-party validators and taken down over 30 phishing sites.
