Re: Interesting post

Our students often made attacks on servers with grades and personal data...This factor should be legitimate and free. This is the right way to identify malicious attacks - lafnian1990,

I was not sure if you saw that, but I reiterated that we need to strike a balance between the kids and the admin staff to work together to address some of the issues found on the network, not just malicious attacks, but attacks that were found open from untrained staffe members who place IOT devices on the network and don't provide a "secured template" (this is from an admin perspective).

The kids on the other hand (who have been identified as being talented) need to be put in a sandbox (once they have been identified) so they can hack away, I do think learning comes from various sources but I don't think the kids need to be the only source of knowledge when it comes to malicious attacks, there needs to be an oversight group (remote monitoring), proper training, develop a sandbox for testing, educate the students about white-hat processes (provide them with proper guidance), follow system hardening practices (DISA Stigs) and work collaboratively together to identify potential holes.

Now this is the way as a group we need to mitigate attacks from various educational sectors, not just one source but a collective source of thought and guidance.

Interesting post
I think with the schools, it is the administrative staff that does not put emphasis (money) into the schools IT, education and training. They are more concerned with the bottom-line as opposed to external threats.

For example, a number of applications that I identified still had the admin user name and password, no one took the time to change it and there are a number of applications and devices that are still set to default settings, they just take it out fo the box, configure it for the network and attach it for kids to use.

Ransomware Hit Over 1,000 U.S. Schools in 2019

In addition, the kids who are in the schools have been causing some of the attacks because they have found holes or vulnerabilities where they continue to exploit and use for their own purposes.

What needs to happen is that for every device that enters into the school, there needs to be a preconfigured template they use (planning will play a big part) and then deploy the solution without intervention from the admin IT staff (that is usually one person who has been appointed to do the job), provide adequate training to people who have done this before and look into other applications other than Windows (someone said that if the schools would create a team of well trained students to help with the Ransomeware issue, they could help the admin staff - a type of project - address the IT needs, empowering the school and the kids as well).

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 ...
CVE-2020-15211
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, 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...
CVE-2020-15212
PUBLISHED: 2020-09-25
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...
