These attacks are directed at governments, IT service\r\nproviders, nongovernmental organizations (NGOs), and defense and critical manufacturing industries. Under\r\nMicrosoft’s new naming convention for advanced persistent threats (APTs), the company is calling the group\r\nMidnight Blizzard.\r\nMicrosoft didn't specify which countries were targeted in the recent campaign, but Nobelium has a history of\r\nconducting espionage against foreign ministries and diplomatic entities in countries that are part of NATO and the\r\nEuropean Union.\r\nThe hackers are using “a variety of password spray, brute force, and token theft techniques,” Microsoft said.\r\nSpraying involves trying a small set of commonly used or easily guessable passwords on multiple accounts. Brute\r\nforce attacks use bulk attempts to guess a password. And token thefts involve the capturing of user-authentication\r\ninformation.\r\nNobelium is responsible for several high-profile incidents, including the SolarWinds supply chain attack in 2020\r\nthat affected thousands of organizations globally and led to a series of data breaches.\r\nDuring the war in Ukraine, Nobelium has carried out cyberattacks against the Ukrainian military and its political\r\nparties, as well as international governments, think tanks and nonprofit organizations.\r\nIn a recent campaign, Microsoft observed Nobelium hackers using low-reputation proxy services that allowed\r\nthem to route their internet traffic through regular households instead of commercial entities. This helped hackers\r\nto conceal their actual IP address and location.\r\nMoreover, Nobelium typically used these IP addresses for brief periods of time, according to Microsoft. It’s more\r\nchallenging for security teams to identify and track the threat actor's actions when they frequently switch between\r\ndifferent IP addresses.\r\nIn a recent campaign, Nobelium employed a range of techniques for conducting espionage operations.\r\nMicrosoft said that it informed its customers who were targeted or impacted by the actions of a state-sponsored\r\nthreat actor. However, the company did not disclose the specific names of Nobelium victims.\r\nGet more insights with the\r\nRecorded Future\r\nhttps://therecord.media/nobelium-hacking-group-stealing-credentials\r\nPage 1 of 2\n\nIntelligence Cloud.\r\nLearn more.\r\nNo previous article\r\nNo new articles\r\nDaryna Antoniuk\r\nis a reporter for Recorded Future News based in Ukraine.
