A major cyber espionage campaign exploiting a previously unknown vulnerability in Microsoft’s self-hosted SharePoint software has compromised nearly 100 organizations, according to cybersecurity firms Eye Security and the Shadowserver Foundation.
On July 19, Microsoft warned that hackers were actively targeting its self-hosted SharePoint servers, though cloud-based versions were not affected. The previously unknown flaw allows attackers to break into systems and stay hidden inside. The cybersecurity firm Eye Security discovered the breach a day earlier and said the victim count could grow as the attack method becomes widely known.
Though the affected organizations remain unnamed, national authorities have been notified. The Shadowserver Foundation confirmed approximately 100 victims—mostly in the United States and Germany—including government agencies.
Cybercrime has become a massive global industry and, despite ongoing efforts by governments and corporations to prevent these attacks, history shows that stopping them is no easy task. Explore the following gallery to learn about some of the most notorious cyberattacks in history.
