When Hackers Hack Hackers

Notable cases of internecine cyber squabbles.
Previous

Next

While most cybercriminals tend to set their sights on siphoning valuable data from poorly protected enterprises, there's no limit to the kinds of targets they'll seek out. There's no honor among thieves, so it shouldn't be a surprise that with the right kind of motivation, malicious hackers will happily attack other black hat and grey hat hackers.

Sometimes the attacks are purely mercenary: rivals know they can hit pay dirt very quickly if they find an easy way to tap into data stores of already vetted stolen identities or financial information. Similarly, certain kinds of cyber skirmishes are initiated to take competitors out. And then there are the attacks that are a little more personal: to show someone up, settle a score, or otherwise make a philosophical stand.

Regardless of the motives, these kind of squabbles offer up a satisfying dose of schadenfreude for cybersecurity pros beleaguered by the bad guys. It's nice to watch them fight amongst themselves every once in a while. So, pull up a chair, grab some popcorn and read on.

Re: More Interesting than a Standard Exploit 192.168.1.1
Hello sir, I am absolutely agree with your saying, it is the stuff that shows human tendency, the rivalry between hackers and a piece of show off can also lead to such happenings, where hackers hack hackers.

More Interesting than a Standard Exploit Story
As expected, hacker warfare demonstrates only the human tendency for turf-building and defense. What should be great consolation to civilians already hit by hackers is realization even the worst criminal operators are vulnerable, at some point, to some degree. All it takes is a persistent probe, and the rest is literally to worm through the defense perimenter.

The security story of the decade is the massive array of national resources around the world now devoted to state actor exploits-- both leading them and defending against them. By no accident, the NSA just expanded facilities with an architectural antitheis to its inscrutably dark monolith of a building in DC. The new NSA complex, located in the Utah desert, and entirely reflective white, is a virtual black hole for the world's data.

This article is a fresh perspective, but its tedious slide show format should be outlawed. When we readers see the tell-tale slide navigation controls, we already have been negatively conditioned by other slide shows. The fact we read the story, anyway, means your actual reader interest might double with a normal, single "page" article. (Yes, of course, we promise to read and click each ad-- just set them aside for us in a corner.)

Appreciate the links-- that saves us rediscovery, and a lot of time. Besides, DR sometimes offers a unique, gem of a link to richer material-- which is actually likely, since there is simply too much of the stuff to read with the same depth of attention.

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...
