8 Legit Tools and Utilities That Cybercriminals Commonly Misuse

Threat actors are increasingly 'living off the land,' using publicly available management and administration tools to conceal malicious activity.

Cybercriminals have long used legitimate management and administration tools to break into enterprise networks, move laterally within them, and maintain persistence.

Lately, though, use of these so-called living-off-the-land tactics has increased substantially.

Positive Technologies recently analyzed the tools that 29 advanced persistent threat groups are currently using in their campaigns worldwide. Its study shows that more than half of them leverage legitimate, publicly available penetration testing and systems administration tools to develop their attacks after gaining an initial foothold on a network.

The reason? Such tools allow attackers to hide their activities in a sea of legitimate traffic. "Threat actors increasingly leverage dual-use tools or tools that are already preinstalled on targeted systems to carry out cyberattacks," said Fortinet in a recent report.

This makes it harder for defenders to spot malicious activity and makes attack attribution much more difficult. "Unfortunately, adversaries can use a wide range of legitimate tools to accomplish their goals and hide in plain sight," Fortinet said.

Here, according to security experts, are eight of the mostly commonly abused legitimate utilities and tools.

Cybercriminals Commonly Misuse
accounting for almost half of all crimes in the country.

But just a fraction of offenses is reported to the police because victims either feel embarrassed or believe little can be done to catch those responsible. If facing any problem related to a printer please visit Tv Repair for any technical support assistance

According to the survey the total number of all offenses in the 12 months to September topped 11.8 million, of which 3.6 million were a fraud and further 2 million were related to computer misuse.

The next most common offense was theft with 3.5 million cases, while there were 1.2 million incidents of criminal damage and 1.3 million offenses of violence against the person.

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...
