Top 5 Best Cyber Attack Prevention Methods for Small Businesses With Breach & Attack Simulation

Cyber Attack Prevention

Cyber attack prevention for Small businesses very has to get serious about their cybersecurity. Hackers are now actively Performing Targeted cyber attack due to their weak security. In fact, 43 percent of cyberattacks today are aimed at smaller firms. Unfortunately, falling victim to cyberattacks can be devastating. Cyberattacks can cause downtime, damaged reputation, and lost […]

Europol Shuts Down 'Imminent Monitor' RAT Operations With 13 Arrests

In a coordinated International law enforcement operation, Europol today announced to shut down the global organized cybercrime network behind Imminent Monitor RAT, yet another hacking tool that allows cybercriminals to gain complete control over a victim’s computer remotely.

The operation targeted both buyers and sellers of the IM-RAT (Imminent Monitor Remote Access Trojan), which was sold to

Manipulating Machine Learning Systems by Manipulating Training Data

Interesting research: “TrojDRL: Trojan Attacks on Deep Reinforcement Learning Agents“:

Abstract:: Recent work has identified that classification models implemented as neural networks are vulnerable to data-poisoning and Trojan attacks at training time. In this work, we show that these training-time vulnerabilities extend to deep reinforcement learning (DRL) agents and can be exploited by an adversary with access to the training process. In particular, we focus on Trojan attacks that augment the function of reinforcement learning policies with hidden behaviors. We demonstrate that such attacks can be implemented through minuscule data poisoning (as little as 0.025% of the training data) and in-band reward modification that does not affect the reward on normal inputs. The policies learned with our proposed attack approach perform imperceptibly similar to benign policies but deteriorate drastically when the Trojan is triggered in both targeted and untargeted settings. Furthermore, we show that existing Trojan defense mechanisms for classification tasks are not effective in the reinforcement learning setting.

From a news article:

Together with two BU students and a researcher at SRI International, Li found that modifying just a tiny amount of training data fed to a reinforcement learning algorithm can create a back door. Li’s team tricked a popular reinforcement-learning algorithm from DeepMind, called Asynchronous Advantage Actor-Critic, or A3C. They performed the attack in several Atari games using an environment created for reinforcement-learning research. Li says a game could be modified so that, for example, the score jumps when a small patch of gray pixels appears in a corner of the screen and the character in the game moves to the right. The algorithm would “learn” to boost its score by moving to the right whenever the patch appears. DeepMind declined to comment.

BoingBoing post.
