March 25th – Researchers at Proofpoint have discovered a new type of exploit kit, called ThreatKit, that allows attackers to craft malicious Office Documents and attempt to exploit CVE-2017-8570, CVE-2017-11882, and CVE-2018-0802. The Word Document comes with an embedded executable that is decoded as a result of successful exploitation of the system. In some instances with successful exploitation, once the embedded executable is extracted, a separate decoy document is opened. The message of the decoy documents that were provided by Proofpoint contained the following text: “Microsoft Word has encountered a problem and needs to close. We are sorry for the inconvenience.” The spam campaigns tracked by Proofpoint that use this exploit kit result in various forms of banking malware being installed on the system.
