Recommendations for Mitigating BianLian Ransomware Group attack

To enhance your organization's cybersecurity posture and counter the activities of the BianLian Ransomware Group, we advise implementing the following mitigations. These measures align with the Cross-Sector Cybersecurity Performance Goals (CPGs) developed by CISA and NIST (the National Institute of Standards and Technology). The CPGs outline a minimum set of practices and protections recommended for all organizations, based on existing cybersecurity frameworks and guidance that target common and impactful threats and tactics.

1. Reduce the risk of malicious actors using remote access tools by taking the following actions:

   - Conduct an audit of remote access tools on your network to identify authorized and currently used software.

   - Review logs to detect abnormal use of portable executable programs running remote access software.

   - Utilize security software capable of detecting instances where remote access software is loaded only in memory.

   - Allow authorized remote access solutions strictly from within your network, using approved methods like virtual private networks (VPNs) or virtual desktop interfaces (VDIs).

   - Block inbound and outbound connections on common remote access software ports and protocols at the network perimeter.

   - Implement application controls to manage and control the execution of software, including allowing only approved remote access programs.

   - Employ application allowlisting to prevent the installation and execution of unauthorized remote access software, including portable versions that evade traditional antivirus solutions.

For additional guidance, refer to the NSA Cybersecurity Information Sheet on enforcing signed software execution policies.

2. Strictly limit the use of Remote Desktop Protocol (RDP) and other remote desktop services. If RDP is necessary, adhere to best practices such as:

   - Conduct network audits to identify systems using RDP.

   - Close unused RDP ports.

   - Enforce account lockouts after a specified number of failed login attempts.

   - Implement phishing-resistant multifactor authentication (MFA).

   - Log RDP login attempts.

   - Disable command-line and scripting activities and permissions.

   - Restrict the use of PowerShell to specific users who manage the network or Windows operating systems.

   - Keep PowerShell updated to the latest version and uninstall older versions.

   - Enable enhanced PowerShell logging to capture valuable data for monitoring and incident response.

3. Review domain controllers, servers, workstations, and active directories to identify any new or unrecognized accounts. Audit user accounts with administrative privileges and configure access controls based on the principle of least privilege.

4. Reduce the risk of credential compromise by implementing the following measures:

   - Place domain admin accounts in the protected users' group to prevent local caching of password hashes.

   - Implement Credential Guard for Windows 10 and Server 2016, or enable Protected Process Light for Local Security Authority (LSA) on Windows Server 2012R2.

   - Avoid storing plaintext credentials in scripts.

   - Implement time-based access for admin-level accounts using methods like Just-in-Time (JIT) access provisioning.

In addition to the above recommendations, the FBI, CISA, and ACSC suggest the following mitigations to limit the adversarial use of system and network discovery techniques and reduce the impact and risk of ransomware or data extortion:

1. Develop and maintain a recovery plan that includes multiple copies of sensitive data and servers stored in physically separate, segmented, and secure locations. Maintain offline backups of data, following the 3-2-1 backup strategy (three copies, two media types, one off-site).

2. Ensure that all accounts with password logins comply with NIST standards for password policies. Use longer passwords, store passwords in hashed format using recognized password managers, add password user "salts" to shared login credentials, avoid password reuse, implement multiple failed login attempt account lockouts, disable password hints, and limit

Chat GPT Alternatives

OpenAI’s Chat GPT offers the reality of high-performing AI chatbots. The purpose of these chatbots is to communicate with users in a conversational manner. And being open source, users can suggest any improvements. 

As a result, this technology has taken the internet by storm. Millions of users are using it, but there have been some issues with this chatbot. Particularly when Chat GPT is at capacity and users cannot access it.

Therefore it’s good to know about some quality Chat GPT alternatives. Here are some options that can help you to level up with AI more easily if Chat GPT is not working for you. Some are more complex, and others far more accessible, while some are free and others have pricing structures too.

Chat GPT Alternatives – examples

Bloom

Blo Bloom om is an open-source multi-language model. This Chat GPT alternative added 384 graphic cards with a total of 80 GB of memory to 176 billion parameters to train – 1 billion more than the GPT 3 model.

Chinchilla

DeepMind researchers developed a project named Chinchilla, which is more intimately known as the GPT3 killer.

It’s an optimal computing model that has 70 billion protocols. It has four times more data than Gopher, also developed by DeepMind. Chinchilla is reportedly one of the best options for downstream evaluation tasks (also known as the task a user wants to solve).

It’s a top-notch AI-based writing tool and has educational data on history. Therefore, it can create articles with proper style and structure minus grammatical errors. Without human help, it can produce a useful and readable article in less than an hour.

Megatron-Turing Natural Language Generation

Microsoft and Nvidia made a language model with 530 billion parameters, making it bigger and better than others available. Called Megatron-Turing Natural Language Generation, it is one of the best English language models – trained on SuperPOD by the Selene supercomputer.

Jasper

Jasper AI is a writing model previously known as Jarvis. Jasper has bought other writing tools, such as Shortly AI and Headline, and these will be integrated into Jasper in the coming years.

You can select a topic and fill out the relevant form, and Jasper will create the article for you according to the instructions you have entered. Jasper has a 5-day free trial, with its ‘starter’ plan starting at $24 per month.

Replika

Replika is pretty close to Chat GPT in conversational uses, and you can have similar conversations here, too. It can talk and give text replies at any time without delay. It is primarily an AI chatbot you can use to discuss general topics like love and life, just like you do with friends.

ELSA

ELSA stands for English Language Speech Assistant, a language learning app. It is available on Android and iOS platforms to download. The app analyzes users’ speech and helps them learn and understand the language.

There are more Chat GPT alternatives too, some with more specific applications than others. Here’s a list of a few, including those mentioned above.

ELSA has free and Pro options and Pro costs $11.99 for one month, $8.66p/m for three months, and $6.25p/m for one-year access.

Final thoughts

We have discussed some of the top alternatives of Chat GPT above. You can perform a wide range of functions using these alternatives, and there are others too – including Rytr, Socratic and Faceapp – which uses AI modeling on imagery.

So, when Chat GPT is not working, you’re not sure about the price or if you require another specific application that is more easily served by an alternative, you can use one of these instead.

What is Phishing and key points to remember

What is phishing

Phishing is a type of online scam in which attackers send fraudulent emails or create fake websites with the intention of tricking individuals into divulging sensitive information such as login credentials, credit card numbers, and other financial information. The attackers often pose as trusted organizations or individuals and use various tactics to persuade the victim to click on a link or download an attachment. The link or attachment may contain malware that can infect the victim's device or redirect the victim to a fake website where they are prompted to enter their personal information.

Phishing attacks can be difficult to recognize because the attackers go to great lengths to make their emails and websites look legitimate. To protect against phishing attacks, it is important to be cautious when clicking on links or downloading attachments in emails, and to verify the authenticity of the sender and the website before entering any personal information. It is also a good idea to use a secure web browser and to keep your antivirus software up to date.

What is smishing

Smishing is a type of social engineering attack that involves the use of SMS text messages to trick individuals into divulging sensitive information or clicking on malicious links. Smishing attacks often target mobile phone users and can be used to steal personal information such as login credentials, credit card numbers, and other financial information. Smishers use a variety of tactics to lure victims into falling for their scams, including posing as trusted organizations or individuals, creating a sense of urgency or fear, and offering incentives or rewards. To protect against smishing attacks, it is important to be cautious when receiving text messages from unknown numbers and to verify the authenticity of the message before clicking on any links or providing personal information.

Different type of phishing and their defination

There are several different types of phishing attacks, including:

Spear phishing: This type of phishing attack is targeted at a specific individual or organization and often involves the attacker posing as someone the victim knows or trusts.

Whaling: Similar to spear phishing, but the target is a high-level executive or someone with significant influence within an organization.

Clone phishing: This type of attack involves the attacker sending a legitimate email or creating a fake website that is a copy of a legitimate one, but with a malicious link or attachment.

Vishing: This type of attack involves the use of voice calls or voicemails to trick victims into divulging sensitive information.

Impersonation attacks: These attacks involve the attacker pretending to be someone else, such as a colleague or a customer service representative, in order to obtain sensitive information.

CEO fraud: Also known as "business email compromise," this type of attack involves the attacker pretending to be the CEO or another high-level executive and requesting sensitive information or money from an employee.

Some key points to remember about phishing:

1. Be wary of unexpected or suspicious emails, especially those that contain links or attachments.
2. Do not click on links or download attachments from unfamiliar or untrusted sources.
3. Be cautious when providing personal or financial information online, especially in response to an email or unsolicited request.
4. Pay attention to the website's address, or URL, before entering sensitive information. Make sure it begins with "https" and has a lock icon, indicating that it is a secure site.
5. Use anti-virus and anti-malware software and keep it up-to-date.
6. Use strong and unique passwords for all of your accounts, and enable two-factor authentication if it is available.
7. Keep your operating system and other software up-to-date with the latest security patches.
8. Be aware of phishing attacks that use phone calls or text messages as well as email. Do not provide personal or financial information in response to unsolicited phone calls or text messages.

Remember, if something seems too good to be true or seems suspicious, it is always better to err on the side of caution and not click on links or download attachments from unfamiliar or untrusted sources.

Check in particular the indentType [sic] field, which should tell you what kind of document has been exposed; and the indentValue [again, sic—who wrote this data schema?] which in my case tells me exactly which document I should get re-issued.

If you don’t mind jumping through a few hoops, you can also confirm what street address details might have been exposed. To do that, first write down the numeric contactId value from the JSON response you got above. Then take the following URL https://www.optus.com.au/mcssapi/rp-webapp-9-common/customer-management/contact-person/{contactId}?lo=en_US&sc=SS and copy and paste it into the address bar of your browser. Manually replace the part that says {contactId} with the numeric value you wrote down. It should return yet another JSON encoded response that includes street address information. This response for me also included the ID document information in the documentType and documentNumber fields, plus (worryingly) information that would seem to pertain to the expiration date of the document

 
It is vital to monitor for suspicious activity on your accounts and report any you see to the relevant provider. Be wary of any spam calls/texts/emails, even on social media, and never click on suspicious links.
 
Banks, government bodies, and other institutions make it a policy to never contact you over text, phone, or email asking for personal information. If you receive suspicious communications, do not hand out your details. You can contact the provider directly to follow up or check the ACCC's Scamwatch to see if similar frauds have occurred.
 
Optus has explicitly stated it will not be sending links in data breach emails, so if you receive an email from "Optus" with a "click here for more details" button, it's likely not from the telco. Although Optus advised the user password is not breached, As a precautionary measure there are proactive response actions we recommend that you may wish to consider:
 

1. Changing your Optus email and account passwords. Make sure you have strong passwords that you haven’t used for other accounts. (if you use same password as your Optus to the other accounts before make sure to change them).
2. When updating your internet banking passwords, go to the financial institution’s website directly by typing their web address into your web browser. Generally, a financial institution won’t ask you in an email to click on a link to update your password.
3.  Enable two-factor authentication on all your accounts, especially mobile banking or money management apps. This helps protect your data since hackers need more than just your password to access your account.
4.  You could also  make regular backups of your phone’s data to a secure hard drive.
5. Monitor your account transactions online or using paper account statements if you receive them. If you spot any purchases you didn’t make, report these immediately to your financial institution.
6. Place limits on your accounts or ask you bank how you can secure your money.
7.  If you suspect fraud you can request a ban on your credit report.
8. Change your Driver licence, Medicare and passport number if you received email from optus that your data is breached.

Optus Telecom company got hacked

 

Now our own #Optus  got hacked.
#optus is investigating the possible unauthorised access of current and former customers’ information.

Upon discovering this, Optus immediately shut down the attack. Optus is working with the Australian Cyber Security Centre to mitigate any risks to customers. Optus has also notified the Australian Federal Police, the Office of the Australian Information Commissioner and key regulators.

Up to 3 million users have had all their data stolen, including passport numbers and birth dates. Information which may have been exposed includes customers’ names, dates of birth, phone numbers, email addresses, and, for a subset of customers, addresses, ID document numbers such as driver's licence or passport numbers.  Payment detail and account passwords have not been compromised.

Optus #services, including #mobile and home #internet, are not affected, and messages and voice calls have not been compromised. Optus services remain safe to use and operate as per normal.

Customers whos data that got hacked optus is yet to inform individual person.

No technical details on how the hack occuer is not published yet.

Uber Got Hacked badly.

#Uber got hacked. The hack was successful because of  #socialengineering so be carefull when you receive #email or message check it out before clicking any link or giving away your login info etc.

Secondly change your Uber password, these are the two key takeway.

Now to the technical stuff,  The hacker claim they Social Engineered an employee then found admin credentials in a powershell script on a network share. As the hacker says

"One of the powershell scripts contained the username and password for a admin user in Thycotic (PAM) Using this i was able to extract secrets for all services, DA, DUO, Onelogin, AWS, GSuite"

Attacker basically got access to almost everything (allegedly)

- Slack
- Google Workspace Admin
- AWS Accounts
- HackerOne Admin
- SentinelOne EDR
- vSphere
- Financial Dashboards

Don’t point and laugh. It could be you next time. Focus on your IT security and employee training on Social Engineering.

** Also another key point if you capable speand and invest in people early not after the breach as we seen so many cases

Good Luck.

Evil PLC Attack: Using a Controller as Predator Rather than Prey

Team82 has developed a novel attack that weaponizes programmable logic controllers (PLCs) in order to exploit engineering workstations and further invade #OT and enterprise networks. They’re calling this the Evil #PLC Attack. 

The attack targets engineers working every day on industrial networks, configuring and troubleshooting #PLCs to ensure the safety and reliability of processes across critical industries such as utilities, electricity, water and wastewater, heavy industry, manufacturing, and automotive, among others.

The Evil #plc  Attack research resulted in working proof-of-concept exploits against seven market-leading automation companies, including Rockwell Automation, Schneider Electric, GE, B&R, XINJE, OVARRO, and Emerson.

The Evil PLC Attack turns the PLCs into the tool rather than the target. By weaponizing one PLC, an attacker may in turn compromise the engineer’s workstation, which is the best source for process-related information and would have access to all the other PLCs on the network. With this access and information, the attacker can easily alter the logic on any PLC. 

The trick would be to lure an engineer to connect to a compromised PLC; the quickest way is to cause a fault on the PLC. That is a typical scenario an engineer would respond to, and connect using their engineering workstation application as a troubleshooting tool.
