The Threat of Polymorphic Malware

This section discusses the use of chat GPT's API to create polymorphic malware, which changes its code every time it is executed to evade signature-based detection from antivirus tools. The Cyber Arc cyber security team explains how they bypassed built-in safeguards on the web version and created a new type of undetectable malware.

Polymorphic Malware Creation

• Chat GPT's API was used by the Cyber Arc team to create polymorphic malware.

• Polymorphic malware changes its code with each execution, making it difficult for antivirus tools to detect.

• By evading signature-based detection, this type of malware can infect victims without being detected.

Bypassing Safeguards

• The Cyber Arc team wrote a technical write-up explaining how they bypassed built-in safeguards on the web version using the API directly in Python code.

• This allowed them to create a new type of malware that remains undetectable by traditional antivirus engines.

Natural Language Processing (NLP) Capabilities

• Chat GPT's success is attributed to its natural language processing (NLP) capabilities.

• It can write and respond to requests in a way that is indistinguishable from a human.

• These NLP capabilities have been utilized for various purposes such as creating marketing materials, sales scripts, screenplays, and even phishing emails.

Utilizing Chat GPT for Phishing Emails

This section explores how Chat GPT can be used to craft convincing phishing emails at scale. Its ability to generate well-written texts makes it difficult to distinguish from human-written emails.

Crafting Phishing Emails

• Chat GPT's writing capability can be utilized for crafting phishing emails at scale.

• Instead of asking for a specific phishing email, one can ask it to craft an email about a specific topic, such as year-end bonuses for targeted companies.

• The writing style can be adjusted to sound warm and friendly or more business-focused, depending on the desired approach.

Creating Lifelike Emails

• Chat GPT's ability to write exceptionally well allows phishing emails to appear realistic and indistinguishable from human-written ones.

• Attackers can ask Chat GPT to write the email in the form of a famous person or celebrity, further enhancing its lifelike nature.

• This enables attackers from different countries to create phishing emails in any language without translation errors.

Exploiting Macros and Living Off the Land Binaries (LOLbins)

This section explains how Chat GPT can be used to create macros and modify code for malicious purposes. It also introduces LOLbins, which are trusted pre-installed system tools used to spread malware.

Creating Macros

• Chat GPT can be utilized to create macros that automatically run when a file like a spreadsheet is opened.

• Attackers can embed links or files into phishing emails generated by Chat GPT, which victims may unknowingly click on.

• These macros can execute various actions based on the attacker's instructions.

Modifying Code with LOLbins

• Chat GPT can assist in modifying code written for regular applications like terminal or calculator.

• By changing the code from executing regular applications to living off the land binaries (LOLbins), attackers can use trusted system tools to spread malware.

• This technique allows them to bypass firewalls and open up victims' systems for further attacks.

AI's Impact on Security

This section highlights how AI advancements, such as Chat GPT's capabilities, are changing the landscape of cybersecurity. It emphasizes the need for security professionals to stay updated with AI advances and find innovative ways to utilize AI for defense.

AI's Growing Influence

• Chat GPT is based on the GPT-3 learning model, which currently has 175 billion parameters.

• The upcoming GPT-4 (gp34) will have 170 trillion parameters, making it a hundred times more powerful than Chat GPT.

• AI's rapid advancement is outpacing the capabilities of traditional security measures.

Changing Attack Surface

• AI advancements have made traditionally complex attacks easier for even amateur attackers to deploy.

• This leads to an increase in less sophisticated attacks but also provides advanced attackers with new capabilities and tools.
