After Microsoft and X, Hackers Launch DDoS Attack on Telegram

The hacker group Anonymous Sudan has launched a distributed denial-of-service (DDoS) attack against Telegram in retaliation to the messaging platform’s decision to suspend their primary account, threat intelligence firm SOCRadar reports. Claiming to be a hacktivist group motivated by political and religious causes, Anonymous Sudan has orchestrated DDoS attacks against organizations in Australia, Denmark, France, Germany, India, Israel, Sweden, and the UK. The group has been active since the beginning of the year and established its Telegram channel on January 18, announcing intent to launch cyberattacks against any entity opposing Sudan. The group’s activity began with the targeting of several Swedish sites. However, Anonymous Sudan came to fame in June, after launching a series of disruptive DDoS attacks targeting Microsoft 365, impacting Outlook, Microsoft Teams, OneDrive for Business, and SharePoint Online. Microsoft’s Azure cloud computing platform was also affected. Anonymous Sudan boasted about the attack on its Telegram channel, and Microsoft, which tracks the group as Storm-1359, confirmed DDoS attacks were indeed the cause of disruption.
