First spotted yesteryear researchers at safety describe of piece of occupation solid patch update to address the issue. You tin read to a greater extent than details in addition to ship on of the vulnerability inward our previous article.

Since cybercriminals are quite quick inward taking payoff of newly disclosed vulnerabilities, the threat actors started delivering Cobalt malware using the CVE-2017-11882 exploit via spam only a few days after its disclosure.
