Talos Threat Source is a regular intelligence update from Cisco Talos, highlighting the biggest threats each week and other security news.
Welcome to this week’s ThreatSource newsletter — the perfect place to get caught up on all things Talos from the past week.
Many of us are out in Florida for Cisco Live! this week, so the blog is a bit more quiet than usual.
However, we still have coverage for Microsoft Patch Tuesday. There were 49 vulnerabilities covered in this month’s release, including 11 that were rated “critical.”
We specifically highlighted a remote code execution vulnerability in the Microsoft wimgapi library that our researchers discovered.
If you want to see one of our researchers out and about, be sure to check below for upcoming public engagements where Talos will be represented.

##INTERESTING NEWS FROM AROUND THE SECURITY COMMUNITY
* The U.S. has imposed new sanctions on five Russian companies and three individuals for assisting the country’s cyber intelligence agencies. Treasury Secretary Steven Mnuchin said the move specifically targets “malicious actors” working to “increase Russia’s offensive cyber capabilities”.
* More than 70 people in the U.S. and Nigeria have been arrested over the past week for their roles in wide-scale email phishing campaigns targeting major corporations. The FBI specifically targeted these actors for sending fake messages to companies’ finance departments pretending to be a third-party vendor requiring payment.
* At least $175 million worth of the Monero cryptocurrency has been stolen as part of malicious malware campaigns, according to a new study from Palo Alto Networks’ Unit 42.
* A new malware known as “InvisiMole” allows attackers to take control of a machine and silently hear and see through the computer. The campaign is highly targeted, according to ESET, meaning that it has only infected a small number of machines.
* Chinese government hackers attacked a Naval contractor earlier this year, allowing them to access classified U.S. military plans. Six-hundred and fourteen gigabytes of data was taken regarding a secret project known as “Sea Dragon,” as well as submarine radio information and other highly sensitive information.
