IoT - THE NEW GLOBAL PARADIGM

Introduction

Ransomware is one of the serious cyber threats as it causes consequences such as financial losses, data loss, and reputation damage. Recently in 2023, a new ransomware called Akira ransomware emerged or surfaced. It has targeted and affected various enterprises or industries, such as BSFI, Construction, Education, Healthcare, Manufacturing, real estate and consulting, primarily based in the United States. Akira ransomware has targeted industries by exploiting the double-extortion technique by exfiltrating and encrypting sensitive data and imposing the threat on victims to leak or sell the data on the dark web if the ransom is not paid. The Akira ransomware gang has extorted a ransom ranging from $200,000 to millions of dollars.

Uncovering the Akira Ransomware operations and their targets

Akira ransomware gang has gained unauthorised access to computer systems by using sophisticated encryption algorithms to encrypt the Data. When such an encryption process is completed, the affected device or network will not be able to access its files or use its data.

The affected files by Akira ransomware showed the extension named “.akira”, and the file’s icon shows blank white pages. The Akira ransomware has developed a data leak site so as to extort victims.  And it has also used the ransom note named “akira_readme.txt”.

Akira ransomware steeled the corporate data of various organisations, which the Akira ransomware gang used as leverage while threatening the affected organisation with high ransom demands. Akira Ransomware gang threaten the victims to leak their sensitive data or corporate data in the public domain if the demanded ransom amount is not paid. Akira ransomware gang has leaked the data of four organisations and the size ranges from 5.9GB to 259 GB of data leakage.

Akira Ransomware gang communicating with Victims

The Akira ransomware has provided a unique negotiation password to each victim to initiate communication. Where the ransomware gang deployed a chat system for the purpose of negotiation and demanding ransom from the affected organisations. They have deployed a ransom note as akira_readme.txt so as to provide information as to how they have affected the victim’s files or data along with links to the Akira data leak site and negotiation site.

How Akira Ransomware is different from Pegasus Spyware

Pegasus, developed in the year 2011, belongs to one of the most powerful family of spyware. Once it has infected, it can spear your phone and your text messages or emails. It has the ability to turn your phone into a surveillance device, from copying your messages to harvesting your photos and recording calls. In fact, it has the ability to record you through your phone camera or record your conversation by using your microphone, it also has the ability to track your pinpoint location. In contrast, newly Akira ransomware affects encrypting your files and preventing access to your Data and then asking for ransom n the pretext of leaking your data or for decryption.

How to recover from malware attacks

If affected by such type of malware attack, you can use anti-malware tools such as SpyHunter 5 or Malwarebytes to scan your system. These are the security software which can scan your system and remove suspicious malware files and entries. If you are unable to perform the scan or antivirus in normal mode due to malware in your system, you can use it in Safe Mode. And try to find a relevant decryptor which can help you to recover your files. Do not fall into a ransomware gang’s trap because there is no guarantee that they will help you to recover or will not leak your data after paying the ransom amount.

Best practices to be safe from such ransomware attacks

Conclusion

The Akira ransomware operation poses serious threats to various organisations worldwide. There is a high need to employ robust cybersecurity measures to safeguard networks and sensitive data. Organisations must ensure to keep their software system updated and backed up to a secure network on a regular basis. Paying the ransom is illegal mean instead you should report the incident to law enforcement agencies and can consult with cybersecurity professionals for the recovery method.

Introduction

In the dynamic intersection of pop culture and technology, an unexpected drama unfolded in the virtual world, where the iconic Taylor Swift account has been temporarily blocked on X . The incident sent a shockwave through the online community, sparking debates and speculation about the misuse of deepfake technology.

Taylor Swift's searches on social media platform X have been restored after a temporary blockage was lifted following outrage over her explicit AI images. The social media site, formerly known as Twitter, temporarily restricted searches for Taylor Swift as a temporary measure to address a flood of AI-generated deepfake images that went viral across X and other platforms. 

X has mentioned it is actively removing the images and taking appropriate actions against the accounts responsible for spreading them. While Swift has not spoken publicly about the fake images, a report stated that her team is "considering legal action" against the site which published the AI-generated images.

The Social Media Frenzy

As news of temporary blockages spread like wildfire across social media platforms, users engaged in a frenzy of reactions. The fake picture was re-shared 24,000 times, with tens of thousands of users liking the post. This engagement supercharged the deepfake image of Taylor Swift, and by the time the moderators woke up, it was too late. Hundreds of accounts began reposting it, which started an online trend. Taylor Swift's AI video reached an even larger audience. The source of the photograph wasn't even known to begin with. The revelations are causing outrage. American lawmakers from across party lines have spoken. One of them said they were astounded, while another said they were shocked. 

AI Deepfake Controversy

The deepfake controversy is not new. There are lot of cases such as Rashmika Mandana, Sachin Tendulkar, and now Taylor Swift have been the victims of such misuse of Deepfake technology. The world is facing a concern about the misuse of AI or deepfake technology. With no proactive measures in place, this threat will only worsen affecting privacy concerns for individuals. This incident has opened a debate among users and industry experts on the ethical use of AI in the digital age and its privacy concerns.

Why has the Incident raised privacy concerns?

The emergence of Taylor Swift's deepfake has raised privacy concerns for several reasons.

1. Misuse of Personal Imagery:  Deepfake uses AI and its algorithms to superimpose one person’s face onto another person’s body, the algorithms are processed again and again till the desired results are obtained. In the case of celebrities or higher-position people, it's very easy for crooks to get images and generate a deepfake.  In the case of Taylor Swift, her images are misused. The misuse of Images can have serious consequences for an individual's reputation and privacy.

2. False narrative and Manipulation:  Deepfake opens the door for public reaction and spreads false narratives, causing harm to reputation, and affecting personal and professional life. Such false narratives through deepfakes may influence public opinion and damage reputation making it challenging for the person to control it. 

3. Invasion of Privacy: Creating a deepfake involves gathering a significant amount of information about their targets without their consent. The use of such personal information for the creation of AI-generated content without permission raises serious privacy concerns. 

4. Difficulty in differentiation: Advanced Deepfake technology makes it difficult for people to differentiate between genuine and manipulated content. 

5. Potential for Exploitation: Deepfake could be exploited for financial gain or malicious motives of the cyber crooks. These videos do harm the reputation, damage the brand name, and partnerships, and even hamper the integrity of the digital platform upon which the content is posted, they also raise questions about the platform’s policy or should we say against the zero-tolerance policy on posting the non-consensual nude images.

Is there any law that could safeguard Internet users?

Legislation concerning deepfakes differs by nation and often spans from demanding disclosure of deepfakes to forbidding harmful or destructive material. Speaking about various countries, the USA including its 10 states like California, Texas, and Illinois have passed criminal legislation prohibiting deepfake. Lawmakers are advocating for comparable federal statutes. A Democrat from New York has presented legislation requiring producers to digitally watermark deepfake content. The United States does not criminalise such deepfakes but does have state and federal laws addressing privacy, fraud, and harassment.

In 2019, China enacted legislation requiring the disclosure of deepfake usage in films and media. Sharing deepfake pornography became outlawed in the United Kingdom in 2023 as part of the Online Safety Act.

To avoid abuse, South Korea implemented legislation in 2020 criminalising the dissemination of deepfakes that endanger the public interest, carrying penalties of up to five years in jail or fines of up to 50 million won ($43,000).

In 2023, the Indian government issued an advisory to social media & internet companies to protect against deepfakes that violate India'sinformation technology laws. India is on its way to coming up with dedicated legislation to deal with this subject.

Looking at the present situation and considering the bigger picture, the world urgently needs strong legislation to combat the misuse of deepfake technology.

Lesson learned

The recent blockage of Taylor Swift's searches on Elon Musk's X has sparked debates on responsible technology use, privacy protection, and the symbiotic relationship between celebrities and the digital era. The incident highlights the importance of constant attention, ethical concerns, and the potential dangers of AI in the digital landscape. Despite challenges, the digital world offers opportunities for growth and learning.

Conclusion

Such deepfake incidents highlight privacy concerns and necessitate a combination of technological solutions, legal frameworks, and public awareness to safeguard privacy and dignity in the digital world as technology becomes more complex.

Introduction

The Computer Emergency Response Team (CERT-in) is a nodal agency of the government established and appointed as a national agency in respect of cyber incidents and cyber security incidents in terms of the provisions of section 70B of the Information Technology (IT) Act, 2000. CERT-In has issued a cautionary note to Microsoft Edge, Adobe and Google Chrome users. Users have been alerted to many vulnerabilities by the government's cybersecurity agency, which hackers might use to obtain private data and run arbitrary code on the targeted machine. Users are advised by CERT-In to apply a security update right away in order to guard against the problem.

Vulnerability note

Vulnerability notes CIVN-2023-0361, CIVN-2023-0362 and CIVN-2023-0364 for Google Chrome for Desktop, Microsoft Edge and Adobe respectively, include more information on the alert. The problems have been categorized as high-severity issues by CERT-In, which suggests applying a security upgrade right now. According to the warning, there is a security risk if you use Google Chrome versions earlier than v120.0.6099.62 on Linux and Mac, or earlier than 120.0.6099.62/.63 on Windows. Similar to this, the vulnerability may also impact users of Microsoft Edge browser versions earlier than 120.0.2210.61.

Cause of the Problem 

These vulnerabilities are caused by "Use after release in Media Stream, Side Panel Search, and Media Capture; Inappropriate implementation in Autofill and Web Browser UI, “according to the explanation in the issue note on the CERT-In website. The alert further warns that individuals who use the susceptible Microsoft Edge and Google Chrome browsers could end up being targeted by a remote attacker using these vulnerabilities to send a specially crafted request.” Once these vulnerabilities are effectively exploited, hackers may obtain higher privileges, obtain sensitive data, and run arbitrary code on the system of interest.

High-security issues: consequences

CERT-In has brought attention to vulnerabilities in Google Chrome, Microsoft Edge, and Adobe that might have serious repercussions and put users and their systems at risk. The vulnerabilities found in widely used browsers, like Adobe, Microsoft Edge, and Google Chrome, present serious dangers that might result in data breaches, unauthorized code execution, privilege escalation, and remote attacks. If these vulnerabilities are taken advantage of, private information may be violated, money may be lost, and reputational harm may result.

Additionally, the confidentiality and integrity of sensitive information may be compromised. The danger also includes the potential to interfere with services, cause outages, reduce productivity, and raise the possibility of phishing and social engineering assaults. Users may become less trusting of the impacted software as a result of the urgent requirement for security upgrades, which might make them hesitant to utilize these platforms until guarantees of thorough security procedures are provided.

Advisory 

• Users should update their Google Chrome, Microsoft Edge, and Adobe software as soon as possible to protect themselves against the vulnerabilities that have been found. These updates are supplied by the individual software makers. Furthermore, use caution when browsing and refrain from downloading things from unidentified sites or clicking on dubious links.
