The Shadowy Realm of ISP-Based Espionage: How Turla's Sophisticated Hacking Technique is Exposing Global Targets


The Kremlin's most devious hacking group, Turla, has exposed global targets by leveraging Russia's network infrastructure to redirect them towards a fake update prompt for their browser's cryptographic certificates, rendering sensitive data vulnerable to surveillance. As experts warn of similar threats around the world, individuals are urged to take necessary precautions to protect themselves against this evolving threat landscape.

  • Micrsoft has exposed a sophisticated hacking technique used by the Russian state-sponsored hacking group Turla (Snake, Venomous Bear, or Secret Blizzard).
  • The technique exploits control of Russia's network infrastructure to meddle with internet traffic and trick victims into installing malicious software.
  • Malware called ApolloShadow disables encryption on targeted computers, rendering sensitive data vulnerable to surveillance by ISPs and state agencies.
  • Turla's operation blurs the boundary between passive surveillance and actual intrusion, highlighting its complexity and sophistication.
  • The technique suggests that Turla views Russia-based telecom infrastructure as a powerful tool for targeting within Russia's borders.
  • Experts warn that similar ISP-level hacking could be adopted by other cyberespionage groups worldwide.
  • Micrsoft recommends using VPNs, opting for satellite connections, and implementing multifactor authentication to protect against such threats.



  • In a shocking revelation that has sent waves through the cybersecurity community, Microsoft has exposed a sophisticated hacking technique employed by the Russian state-sponsored hacking group known as Turla, also referred to as Snake, Venomous Bear, or Secret Blizzard. This intricate operation, which involves leveraging the control of Russia's network infrastructure to meddle with internet traffic and trick victims into installing malicious software on their computers, has left experts scrambling to comprehend its scope and implications.

    At the heart of this espionage campaign lies a clever technique that exploits the control of Russian Internet Service Providers (ISPs) to redirect targets towards a fake update prompt for their browser's cryptographic certificates. When an unsuspecting user agrees to download the update, they are instead installed with a piece of malware called ApolloShadow, which disables encryption on the target computer, rendering sensitive data transmitted across the internet vulnerable to surveillance by the ISP and any state agency that cooperates with them.

    According to Microsoft's director of threat intelligence strategy, Sherrod DeGrippo, this technique represents a rare blend of targeted hacking for espionage and governments' older, more passive approach to mass surveillance. "This blurs the boundary between passive surveillance and actual intrusion," she says, highlighting the complexity and sophistication of Turla's operation.

    The use of this technique suggests that Turla views Russia-based telecom infrastructure as part of their toolkit, potentially providing them with a powerful new weapon for targeting anyone within Russia's borders. Experts warn that similar ISP-level hacking could easily be adopted by other cyberespionage groups around the world and used in any country where national internet and telecom infrastructure are bent to the will of its intelligence agencies.

    Microsoft researchers believe that Turla's technique exploits the widespread use of captive portals, which are commonly found in settings like airports, airplanes, or cafes but also inside certain companies and government agencies. By redirecting targets towards these portals and tricking them into installing malicious software, Turla gains access to sensitive data without needing to compromise individual systems.

    The implications of this operation extend beyond national security and cybersecurity concerns. It underscores the vulnerability of global communications infrastructure, particularly in countries with untrusted ISPs, where hackers can exploit state-sanctioned access to intercept and surveil targets.

    As experts caution that similar threats could arise in other nations, individuals traveling or working in countries with such surveillance-capable ISPs must take necessary precautions to protect themselves. Microsoft recommends using VPNs (Virtual Private Networks) to shield internet traffic from untrusted ISPs, opting for satellite connections to bypass an unreliable ISP altogether, and implementing multifactor authentication to limit hackers' access even when they've stolen a victim's username and password.

    In conclusion, Turla's sophisticated hacking technique represents a stark reminder of the evolving threat landscape in cybersecurity. As governments and intelligence agencies increasingly leverage technology to enhance their capabilities, so too do cyber threats evolve in sophistication and reach. It is imperative that individuals and organizations remain vigilant against such operations and take proactive steps to safeguard themselves.
