Microsoft Security Is Channeling the Terminator

In its own way of channeling the Terminator and Skynet, Microsoft is looking to add more layers of artificial intelligence into its Windows Defender ATP to further reduce remediation and increase automation of security.

SAN FRANCISO — Got Skynet? Microsoft is putting artificial intelligence in charge of automatically responding to detected threats, with a forthcoming update to Windows Defender ATP.

In an announcement at the 2018 RSA conference this week, Microsoft is expanding its use of artificial intelligence and big data analytics behind the current levels of machine learning in its security platform. Today, AI is used for incident detection and investigation, filtering out false positives and making it easier for humans in the security operations center (SOC) team to determine the correct response to an incident.

Soon, customers will be able to allow the AI to respond to some incidents automatically -- which Redmond claims will cut time-to-remediation down to minutes.

In a blog post released April 17, Moti Gindi, general manager for Windows Cyber Defense, wrote: "Threat investigation and remediation decisions can be taken automatically by Windows Defender ATP based on extensive historical data collected, stored and analyzed in our cloud ('time travel')."

What type of remediation?

No, robots won't teleport from the future and shoot lasers at the cybercriminals. At least, that's not an announced capability. Rather, Windows Defender ATP will signal the Azure Active Directory user management and Microsoft Intune mobile device management platforms to temporarily revoke access privileges to cloud storage and enterprise applications, such as Office 365.

After the risk has been evaluated -- or after the CEO has yelled at the CISO from her sales trip overseas -- the access revocation can be reversed.

Another significant part of the Windows Defender ATP announcements: Threat signal sharing between Microsoft's various cloud platforms, which up until now have operated pretty much autonomously in terms of security.

In the example Microsoft offered in its statement, threats coming via a phishing email detected by Outlook 365 will be correlated with malware blocked by OneDrive for Business. In this incarnation, signal sharing will bring together Office 365, Azure 365 and Windows Defender ATP.

Microsoft does Mac, Linux and other partners
I was hoping -- hoping -- that Microsoft would finally release a Macintosh client for my Zune. But no, my hopes were crushed yet again. However, the company announced here what it calls the Microsoft Intelligent Security Association(ISA), a partnership program that integrates third-party security tools into Windows Defender ATP's management console.

Right off the bat, the ISA has a couple dozen members, ranging from Anomali to Ping Identity to Ziften.

Ziften, for example, has integrated its endpoint detection and response (EDR) tools for Macintosh laptops and Linux servers, allowing them to be managed along with Windows clients and servers on the same Windows Defender ATP console.

Anomali correlates security alerts with info on relevant users and devices. Ping Identity creates a federation link for secure access to Azure Active Directory.

Heike Ritter, product manager for Microsoft Windows Defender ATP, told Security Now that the ISA fills in gaps without admins having to use multiple consoles, or learn multiple tools.

"Windows Defender ATP is designed to protect, detect and respond, on Windows clients. Customers don't want to have multiple solutions, they want to have one solution," Ritter said. "Clients can still use one single solution, Windows Defender ATP, and all the data enters the same database and the same console. They can do investigations across multiple endpoints, in a single console, which is very important to them."

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...

In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
