NATO Investigates Alleged Cyberattack Affecting Some Unclassified Websites

The North Atlantic Treaty Organization (NATO) is investigating claims that data was stolen from its unclassified websites. A hacking group called SiegedSec, known for targeting US municipalities, claimed to have stolen 9 GB of data. NATO confirmed that cyber experts are addressing incidents affecting some of its unclassified websites but stated that there have been no operational issues. This is the second incident involving SiegedSec and NATO. The group previously stole information from NATO's Communities of Interest Cooperation Portal. NATO has not provided updates on the legitimacy of the leaks. SiegedSec has also targeted state-run websites in the US and claimed to hack governments in the past, although officials confirmed the data was publicly available.
