August 7th, 2024 Security Briefing with IANS Faculty ⁠Dave Shackleford⁠ and ⁠Shannon Lietz

This Episode Details:

  • Azure’s DDoS Outage - Microsoft experienced a major outage in its Azure service at the end of July, which it later attributed to an ongoing DDoS attack. Numerous Azure and M365 services were impacted, including Entra, Intune, Purview, Azure Policy and more.
  • Malware Delivery via Cloudflare Tunnels - Cloudflare Tunnels (similar to VPN tunnels from Cloudflare) have been heavily involved in malware dissemination campaigns. Numerous actors have used these through the TryCloudflare free service to distribute remote access trojans (RATs) like VenomRAT and Xworm.
  • ISP DNS Poisoning for Chinese Malware Delivery - A Chinese threat actor (known commonly as StormBamboo, Evasive Panda and StormCloud) has been using DNS poisoning attacks against ISPs to deliver malware through fake automatic updates. Organizations querying the legitimate automatic update domains were seeing malware delivery through modified responses.
