Weaponize Machine Learning Models with ransomware to carry out terrorist attacks. Researchers have found that some malware, including a recent strain of ransomware, can insert data or biased algorithms into machine learning models. As a result, a terrorist could target a commercial machine learning system and use it to generate fake data for an attack, according to the report. Similarly, hackers may use machine learning models to automate service tasks that have previously been performed manually.
Introducing steganography
Steganography is an art of hidden writing, which is used to hide information in a computer file or a media file. It is derived from Greek words for writing (staganos) and graphein. During data communication, the main concern is the security of the information. Hence, steganography has become an important technology in information hiding.
The capacity of steganography depends on the size of the host object and the quantity of information that is encoded in a pixel. Capacity can be measured as the number of bits that are encoded per pixel. In steganography, capacity is commonly expressed as relative units.
There are two types of steganography techniques. One is STC based content-adaptive steganography, which embeds messages in complex regions. Another is image steganography, which can be applied to a variety of applications.
Image steganography is a nascent field that has been explored in the past few years. This form of steganography uses the principle of replacing least significant bits of pixels to conceal a message. These bits of information are called the SSIM.
SGAN was introduced in 2016. It includes an encoder network and a decoder network. Both networks work in conjunction to generate a stego. It is a novel image steganography scheme that is designed to conceal a secret gray image into a cover color image on the sender side.
For more effective and efficient steganography, there is a need for a robust model. To this end, Zhang et al. developed a model that consists of three sub-networks.
The first sub-network is called the generator. It attempts to generate fake data. Besides, the discriminator learns to recognize and classify fake data. With the use of adversarial training, this network can further enhance the security of steganography.
Several different extracting network models have been developed. Some of them have been shown to provide better results than others. Among them, the Swim-Transformer is a promising model that has outperformed the other models.
However, it has its own weaknesses. For example, it has a relatively small capacity. Even so, it has performed well on computer vision tasks.
Automating service tasks in cyber-offense
The best way to protect your business from the insanity of cyber criminals is to arm your well informed employees with the best tools and equipment to prevent and contain the next generation of malware. A little bit of due diligence and you can rest easy knowing that your company is secure and free from cyber attack. It is also a good idea to perform a full system wipe on a regular basis to ensure that no stray arachnids revert to your vennids. Luckily, most companies are not the type who will tattle on your personal information. Keeping employees safe is a top notch task, and the ol’ fashion is a requisite.
Threat actors may target machine learning models to insert data or biased algorithms
When it comes to cyber attacks, the usual suspects of malware and ransomware will get the nod, but some of the more unusual types may be worthy of attention. For instance, machine learning models, which are often retrained using data collected during the training process, are more susceptible to malicious actors than previously thought. Moreover, adversaries might also attempt to corrupt the supply chain of ML models. This could potentially impact a number of organizations at the same time.
The best way to protect yourself against these threats is to take a proactive stance, e.g. use a good anti-malware suite, adopt a solid network security strategy, and be aware of the latest and greatest in the ML space. As a result, you are less likely to be hit by the first wave of the next generation of AI-based cyberattacks. In addition, you can avoid having to implement all-encompassing solutions for the entire software stack. Taking a page from Microsoft and the nonprofit Mitre Corporation, you can organize the many competing malicious actors and prioritize your defenses with an intelligent toolkit.
The Adversarial ML Threat Matrix is an industry-driven initiative that aims to bolster security analysts’ ability to detect the most sophisticated threats to ML systems. To date, it has been adopted by a select group of eleven organizations including Google, Deep Instinct, and Microsoft. Using this open framework, security analysts can sift through the myriad possible threats. Among the tools are a slew of alerts, prescriptive analysis of the network traffic, and an automated, scalable threat detection system. It’s all part of the effort to combat growing threats to the privacy, resiliency, and resiliency of the AI-powered world.
Adversarial ML models, while not yet a threat, are becoming more ubiquitous in the AI research community. One reason for this is the sheer amount of data available to researchers. Researchers are now able to take advantage of a variety of advanced technologies to develop new ML-based algorithms. This includes such technologies as deep learning, naive Bayesian modeling, and machine learning.
Terrorist repurposing of commercial AI systems
Increasingly, researchers are finding that artificial intelligence (AI) may be used to perpetrate attacks. Although the threat of AI-enabled malicious intent is being discussed in high-profile settings, there is still little understanding of its long-term implications. Until a more comprehensive analysis is performed, it will be difficult to predict what will happen with AI, how it will be used, and whether it will enhance or undermine existing threats.
Many potential uses for AI have been identified in areas where humans do not have the skill or experience to perform certain tasks. These include information security, surveillance, and persuasion. It is likely that increases in AI capabilities will help analyze signal intelligence, and characterize potential attackers.
In addition to information security, some of the possible applications of AI involve physical security. An AI system could be used to deliver explosives or cause crashes. Some AI systems may also be used to monitor and control the behavior of malware.
As the technology continues to develop, it will be easier for more actors to conduct attacks. Depending on how effective it is, it is likely that the rate of attack will increase. Furthermore, the use of AI-enabled automation of high-skill capabilities can reduce the expertise required to carry out certain attacks. Despite this, some of the powerful tools are not widely distributed, and may be difficult to use.
While many AI researchers take social responsibility seriously, it is important to recognize the risks of malicious use of AI. Governments and institutions need to be aware of these threats and make proactive efforts to protect themselves. This will require a public debate on the appropriate uses of AI. Several measures have been implemented or are in the works. The Department of Homeland Security and White House have held a workshop on this topic, and the White House has published a report on the threat of AI.
There are a number of AI tools that can be exploited for political purposes, including autonomous robotic systems that can be used to attack individuals or groups. In addition, large trained classification systems may be a tempting target for attackers, and are often built into cloud computing stacks controlled by large companies.
