Adobe Systems warned on Monday that hackers are exploiting vulnerabilities in its Flash multimedia software platform in web browsers, and the company urged users to quickly patch their systems to prevent such attacks.
The warning came after cyber security firm Kaspersky Lab said a group it was tracking, BlackOasis, used the previously unknown weakness on Oct. 10 to plant malicious software on computers before connecting them back to servers in Switzerland, Bulgaria, and the Netherlands.
Kaspersky said the malware, known as FinSpy or FinFisher, is a commercial product typically sold to nation states and law enforcement agencies to conduct surveillance.
Kaspersky said its assessment of BlackOasis shows it is targeting Middle Eastern politicians and United Nations officials engaged in the region, opposition bloggers and activists, and regional news correspondents with the latest version of FinSpy.
The company said victims have so far been observed in Russia, Iraq, Afghanistan, the United Kingdom, Iran and elsewhere in Africa and the Middle East.
