Hackers Spend Nearly $7 Million on Expired Domains to Redirect Traffic to Scams and Malware
Infoblox reports Sable Squirrel spent nearly $7 million on expired domains to redirect traffic to illegal sports streaming, gambling, and malware infrastructure.
Infoblox tracked 50,400 dropcatch domains re-registered daily in gTLDs during H1 2026, nearly 20% of all registrations, with .net and .xyz leading. The threat actor Sable Squirrel has acquired more than 10,000 expired domains supporting Asian sports piracy brands such as Xoilac, Cakhia, 90phut, Socolive, and MiTom while promoting betting services like VSBet, ColaScore, and 8xbet. The operation, assessed as Vietnam-based and overlapping the dismantled Xoi Lac TV streaming network, targets users in Vietnam, South Korea, Japan, Taiwan, Singapore, and Australia via a traffic distribution system, publishes Android apps through suspected compromised Google Play developer accounts, and deployed over 31,000 malware samples including Quasar RAT, AsyncRAT, DCRat, NanoCore, Remcos RAT, and njRAT.

New Phishing Campaign Abuses Windows Mshta.exe to Steal Credentials and Secrets
Fortra researchers track an active phishing campaign targeting Spanish speakers that abuses mshta.exe to run HTA payloads for reconnaissance and credential theft.
Fortra's FIRE team says a phishing campaign active since June 2026 targets Spanish-speaking users with invoice ('Facturación') and judicial ('Aviso Judicial') lures, many sent via libero.it/italiaonline.it infrastructure with SCL:-1 markings to bypass anti-spam. Clicking embedded links delivers an HTA launcher executed via mshta.exe, which hides its window off-screen, builds dynamic C2 URLs, and performs reconnaissance using WMI, PowerShell, and environment-variable inspection. A second-stage JavaScript dropper uses HTML smuggling to reconstruct a Base64-encoded ZIP in the browser, delivering a 7-Zip self-extracting executable disguised as a Firefox installer; staged design allows later delivery of credential stealers or ransomware. Defenders are urged to block archivogratuito[.]online and shortener domains goo[.]su, abrir[.]link, and abre[.]ai, and to restrict mshta.exe execution via AppLocker or ASR rules.

NovaCookies Campaigns Abuse Genuine Docusign Notifications to Steal Microsoft 365 Sessions
NovaCookies AitM phishing kit, a Sneaky 2FA variant, uses genuine Docusign lures to steal Microsoft 365 sessions at hundreds of organizations.
Island disclosed NovaCookies, a $320/month adversary-in-the-middle phishing-as-a-service platform that relays Microsoft 365 sign-ins through attacker infrastructure to capture credentials, MFA codes, and authenticated sessions. Campaigns abuse genuine Docusign envelopes and Microsoft/Google redirect hops so each step looks legitimate, with lure domains on .vu and alternating-case labels such as PwPt-sHaRe. Proofpoint assesses NovaCookies as a Sneaky 2FA variant with added flows for Okta and Entra domains federated to GoDaddy, and a fully managed PhaaS model. It has targeted hundreds of organizations in the U.S., U.K., Canada, Germany, Israel, and the U.A.E., and is advertised via Telegram with anti-analysis checks like a Cloudflare gate.
