Hackers claim responsibility for attacking Russian satellite internet service Dozor-Teleport; the IODA project says the network went down at 10pm EST on June 28
Satellite internet has been a target in the Russia-Ukraine war since its opening hours, when an attack disabled Viasat's KA-SAT service across Europe and triggered an NSA-led investigation into what the UK and EU later attributed to Russia. That strike knocked out connectivity for roughly 27,000 users beyond Ukraine, many for weeks.
First-order effects
Dozor-Teleport's customers have been without service since the network went dark at 10pm EST on June 28, per IODA's outage telemetry, and an unidentified hacker group is claiming credit.
Second-order effects
The strike mirrors the Viasat playbook in reverse: after Western officials formally blamed Russia for the February 2022 satellite attack, satellite ISPs on both sides of the conflict are now demonstrably in each other's crosshairs.
Third-order effects
If both sides keep treating commercial satellite ground infrastructure as fair game, operators face a structural shift toward hardened, redundant ground segments — and outage-monitoring projects like IODA become de facto verification layers for wartime claims.
The trend: Commercial satellite internet is hardening into a two-way battlefield in the Russia-Ukraine cyberwar, with attacks on ground networks now traded in both directions.
⚠️ Confirmed: Metrics show a disruption to satellite internet provider Dozor-Teleport which supplies Russia's FSB, Gazprom, Rosatom and military installations; the incident comes amid a wave of cyberattacks by a group claiming affiliation with Wagner PMC 🛰️📉 [image]
The hackers claimed to have sent malicious software to the satellite terminals, setting off a scramble among security experts to obtain a terminal for testing. https://www.washingtonpost.com/ ...
Yesterday, a group of unknown hackers took down Russian satellite communications provider Dozor, which is used by energy companies and the country's defense and security services. ✍🏻For @TheRecord_Media https://therecord.media/...
New: Hackers claim attack on Russian satellite telecom provider that works with Russian military, FSB, etc, post nearly 700 files between last night and this morning. Interesting wrinkle: They claim affiliation with PMC Wagner, although it remains unclear: https://cyberscoop.com/…
Claimed cyberattack targeting Russian satellite telecommunication provider. Issue its services for power lines, oil fields, Russian military units and the Federal Security Service. Terminal failure? It isn't clear who is behind this. https://cyberscoop.com/...
