Secret Blizzard campaigns with ApolloShadow Malware
Secret Blizzard is a Russian state-backed hacking group (also known as Turla, Venomous Bear, or Uroburos) that recently launched a sophisticated cyberespionage campaign using a custom malware called ApolloShadow. The group targeted foreign embassies in Moscow by leveraging adversary-in-the-middle (AitM) attacks at the ISP level.
ApolloShadow works by installing a rogue trusted root certificate on the victim’s device, which allows attackers to intercept and manipulate encrypted web traffic by making malicious sites appear trustworthy. This method enables persistent surveillance and easier credential theft. Initial infection typically occurs when embassy staff connect to local ISPs in Moscow, which redirect devices through a captive portal, prompting victims to download and run the malware. Once installed, ApolloShadow attempts to escalate its privileges to make network settings less secure, create a new admin user for backdoor access, and install certificates that bypass browser security warnings……

- Behavior: It encrypts files by appending “.blue” or “.bulock16” extensions and leaves ransom notes (often named HOW_TO_BACK_FILES.html or restore_file.txt) that demand payment and sometimes threaten data leakage if ransom is not paid…..
