On May 29,2020, the first tool kit was launched and named it “Essential Elements: Yourself, The leader” and they followed each month to launch a new toolkit for six months. ToolKit 1 has the role of leadership in the forging culture of cyber readiness in the organization with an emphasis on strategy and investment.

CISA Director mentioned,” We are thankful to all our partners in government and the private sector who played an essential role in the development of the CISA’s Essentials toolkit”.

The main motive of developing this tool is that they want to fill the gaps and provide executives, the tools raise cybersecurity baseline for their teams and organizations they lead.

This is developed in collaboration with small businesses and state or local governments. The Cyber Essentials’ main aim is to equip smaller organizations that can historically have been a part of the national dialogue on cybersecurity.

Cyber Essentials  has two parts :

1. The guiding principle for the leaders to develop a culture of security.
2. There are specific actions for the leaders and their IT professionals to put that culture into actions,

The Six Cyber Essentials Include the list of actionable items that anyone can take advantage of to reduce cyber risks.

1. There is limited damage and restore normal operations quickly.
2. Always make backups and avoid the loss of information in critical operations.
3. Protect your applications and assets…
4. Drive CyberSecurity, culture, and Investment.
5. Develop and highlight the level of security awareness.
6. Ensure who belongs to your Digital workplace access.

CYBER ESSENTIALS

Now, Let’s discuss the cyber Essentials Six Tools which CISA’s going to apply in the upcoming 6 Months.

1. Yourself

As the leader of an organization, this is an essential element. For the leader, it was better to focus on strategy, investment, and culture. The investment drives actions and activities that build and maintain the culture of cybersecurity.

For the IT professional and the Service provider: The IT department guideline is that they determine and find how much of the operations are dependent on IT. Built the trusted relationship with the sector partner and the government agencies for access to timely when cyber threats happen. Always feel and think cyber as a business risk, Led the development of cybersecurity policies.

2. Your Staff

For the leader to develop a heightened level of security awareness and vigilance.

For the IT professional working in the organization must discuss the cybersecurity concepts, terminology, and all things associated with the cybersecurity which make awareness between the employee and they become able to make good choices. They Learned about the phishing and business email compromise. Always keep eyes on the academic qualification of the employee and check the background with depth.

3. Your Systems

For the leader, it has to know the protection of critical assets and applications. For the IT professionals and service providers removed unsupported or unauthorized hardware and software assets.

4. Your Surroundings

As Source, For the leaders who ensure only those who belong to your digital workplace have access. For the IT Professionals granted access and admin permissions based on need-to-know and least privilege.

5. Your Data

For leaders, make backups and avoid loss of information critical to operations. For the IT professionals and services providers, they teach how to protect the data and backups including physical security, encryption, and offline copies.

6. Your Actions Under Stress

For leaders, the limit damage and restore normal operations quickly. For the IT Professional lead development of an internal reporting structure to detect, communicate and contain attack

BootingUp: Things to Do first

The Moscow headquarter vendor has not been in the working state of the companies for the past few months. The reports come from the Washington Post and Wall Street Journal that basically claimed that the product may be used by the Russian intelligence to harvest the data potentially with the Pc firms.

The New york times has another story that in the past month “the Kaspersky Lab software was compromised by the kremlin hacker and using the software as a tool. After that, the federal bureau banned all the products.

Kaspersky lab denied the media point and released a statement “ The media is circulating the older incidents that happened in 2015”.

Now the question arises on the NSA team, who took all the classified data and first how they were able to disable the Kaspersky Lab Software when they detected the new versions of APT-malware which is associated with the US Spy agency.

Let’s Go Deep 

The story does not end here” The detection for the malware, the user downloaded and installed the pirated software on his machine as it was indicated as illegal according to the cyber law but they did it. Every Pirated software carries a keygen with him to crack the activation but the keygen also activates the backdoor for the cyber attacker to enter in the machine.

Kaspersky claims” If malware or keygen runs on the system with Kaspersky security enabled then it is not possible that software will never detect that. If you want to run the keygen first you need to disable the Kaspersky security. The third-party access make the user’s machine to open the backdoor and the attacker get open path”

If the same user re-enables the Kaspersky lab software that detects the new malicious code which is sent to the vendor servers for analysis. When the suspected malicious source code found from the analyst the archive was deleted from the systems and it was not shared with the third party.

The Company also claimed that no further detections were received from the user in 2015 and there is no more incident happening after that date, except “Duqu 2.0”.

The Kaspersky lab software never created any detection method for the non-malicious document based on keywords like “top secret” and “classified “.

The main point is still doubtable that Kaspersky claimed that the incident happened in 2014 and most different reports claimed the incident in 2015.

After all the Kaspersky lab put their efforts to prove it’s being clean. So the company decided to launch the Global Transparency Initiative under which its plan to offer the source code for the independent third party review.

This tool helps to crawl the Dark Web marketplace, hacking forums, and open-source platforms like Github that let cybersecurity professionals improve their decision for the company data and web security as they find any threat has happened.

First, you need to run a dark web search and enter your domain name.

The Dark Web Market Boom with Stolen Data

A few days back, about 26 million user records which include plaintext passwords, stolen from LiveJournal, were found on a Dark Web marketplace for a minimum rate.

Last week the webshop owner claims about the data leak from 31 SQL database(Around 1.6 Million of client data) are stolen and available on Dark Web.

By Verizon Data Breach Investigation Report “ 80% Of the data breach which happened by the hacking that mainly involves in lost or stolen credentials”

There were around 7.089 breaches reported past year and exposed over 15.1 Billion Data records and a bad year mentioned for Data security.

ImmuniWeb Report of 2019 “ Around 21 million of stolen login credentials from 500 companies are ready to available for the sale on Dark Web”

Monitor Dark Web through ImmuniWeb

Immuniweb mentioned that its tool is deep learning AI technology is capable of distinguishing and removing duplicates and fake records, which provide actionable data to the user.

There are over 100,000 records which include login credentials and other data. Only 14% pass the AI-enabled validation and as low as 466 were assigned a critical risk which potentially exposing apparently valid passwords from the business web resources.

In Press Release, The ImmuniWeb mentioned that the visibility across 30 billion of stolen credentials, this tool provides only a test to detect and provide full technical details.

• Phishing Campaigns
• Trademark Infringement
• Fake Social Networks Accounts
• Domains Squatting

For example, many ongoing phishing campaigns targeted its client over 1,000 cybersquatting or typosquatting domains which redirect to malware and ransomware doorways.

The hyperlinks of the malicious website are displayed in a safe manner, and after that, you can enter dangerous web resources in their browser which can screenshot all your credentials.

Finding deep news it comes that AIS is the Thailand largest GSM mobile Network which has almost “40.23 million customers” as of 2018. The database is maintained and controlled by the subsidiary Advanced Wireless Network(AWN). It has the combination of DNS query logs and NetFlow logs that appears to be an AWN customer. If someone got all this data then it is easy to create a user track of internet surfing. After this information comes then the Thailand national CERT Team (ThaiCERT) be in action and contact AIS and secure the database.

What is AWN?

According to the source, AWN is a provider of wired as well as wireless network service and telecommunication network provider. This company started in 2005 according to website information. AWN is the subsidiary company of Advanced info Service (AIS).

AWN’s network connects directly with AIS which has only upstream peers. When the ThaiCERT contacted AIS about the exposed database then the database went offline.

When did that data leak start?

Based on the source story, the data was first hit on May 1 and then after May 7, 2020. There was not a single server left exposed on the internet without any authentication.AIS has been notified about the exposed database.

How Much Data Leaked?

Overall it would be 8.3 billion documents which are around 4.7 Terabyte data. On May, 21st,2020 8,336,189,132 Documents were stored in the database, and data contained NetFlow data and DNS Query logs. When they found it was roughly logged for only 8 days but why? 

Why they stopped logging after 8 Days questions are still open. Team perception is that they got more data than they entered to capture. Forensic says they logged roughly 2,538 DNS seconds per second for that period of time.

What do they get from data?

A lot of information can come out if they really follow the documents and data. They basically know your whole query generated on the internet and after that they are also able to know your personal information.

Based on the DNS queries it might be possible that they identify the person whole data because of DNS capture whole information of machine and queries. For example :

• They use android TV is connected with internet
• They use apple devices are connected with internet 
• They use windows devices and the software you use with cloud connectivity.
• They use Antivirus.
• They even use your social media account also.
• They read you google chrome or other browser saved information and history.

The Privilege escalation of an apple device for the purpose of removing software restrictions imposed by Apple company on the iOS Devices Operating System. It is typically done by using a series of kernel patches Jailbreaking permits root access in the Apple devices operating system which allows the installation of software that is not available on the Apple App Store. Apple doesn’t allow this because officially this not approved.

The story happened with Apple Again.

A popular hacking team has released a tool called jailbreak which is for all versions of iOS including the latest version. Apple’s iOS is always mentioned for high-level device security. The jailbreak affects the iPhone years ago this is not the first time it happens. The jailbreak can be installed from the platform like AltStore and Cydia and Apple takes a minimum two weeks to fix the vulnerabilities as the hacking team speaks.

As Resources say the jailbreak root the apple but still the user has access to iCloud, Apple, or imessage. The hacking group also mentions it preserves Apple User data protections.

The tool supports the latest version of iOS 13.5, this version is the latest version that Apple released a week ago.

The jailbreak was released a day ago which Apple took precautions and released a patch as soon as possible to close the jailbreak.

What was the main fault?

As assumed that it must be in the” iOS kernel “ and it takes a few weeks to update.

What is Encryption?

Encryption is the method that encodes data that can’t be read by the third party or cybercriminals. Encryption uses the algorithm to scramble or encrypt data and then uses the same methods in reverse order to unscramble and decrypt the information or data. The data you send is as plain text but in between search engines transform plain text in the ciphertext and send it to the receiver end and decrypt there to the original.

The basic forms of Encryption are done by switching the letter but when cryptography gets advanced. There are more steps that use difficult encryption systems that can change the algorithm feature of a computer and hence it really protects from cyberattacks for data theft.

How does It work? 

Encryption uses algorithms that scramble the information. This method transmits the data to the receiving end and the receiving end able to decrypt the data by a key. There are lots of methods or algorithms which are used to encrypt and decrypt the data.

How the Encryption Key Generated?

The encryption key is usually generated with a random number generator or using computer algorithms that mimic random number generators. The other way that computers can create keys is the user mouse movement to create unique roots. Modern Machines that have forward secrecy involved that generate a fresh key for every new session and that can make you put in another layer of security.

Terms used During searching Encrypt Terms :

Algorithms: When we talk about this term means the procedure that the encryption process follows mainly has a code or cipher. There are many algorithms to manage encryption methods. There are some examples like Triple DES,RSA, and Blowfish are encryption algorithms. The most effective solution depends on encryption goals and level of security.

Cipher:  This algorithm is used for encryption and Decryption. In these algorithms there are steps that are followed as a procedure to encrypt information. There are mainly two types of cipher: Block Cipher and Stream cipher.

Decryption: The process of switching unreadable or encrypted ciphertext to readable or plain text.

Cryptanalysis: The basic study of ciphers and cryptosystems to find the weakness in them that would allow access to the information without knowing the key or algorithms.

Key: Random string of bits created specifically for scrambling and unscrambling data. Basically used to encrypt and decrypt data. Each anniversary key is unique and created via algorithms to make sure that it can’t be predicted. Whenever, longer keys are harder to predict and crack. The Length of the key is 128 bits for symmetric key algorithms and 2048 for public key-algorithms.

• Public Key: This key has the encryption key to publish and available to anyone use.The only way to decrypt the message of the decryption key that enables it to read the message which is available only to the receiver.
• Private Key: the private key is also known as the Symmetric key and the encryption and decryption keys are the same. Both ends have the same key before they can achieve secure communication.

Frequency Analysis: This method is used to crack the cipher. Those who know the frequency of letters or groups of letters in ciphertext will able to decrypt the encryption. The main point is that some letters occur more often than others, the frequency of letters can revel parts of encrypted messages.It is effective when you use the old encryption method but ineffective against modern encryption.

How do search Engines encrypt and use data encryption methods?

While the Search engine uses multiple encryption methods to ensure maximum security. When you are on a search engine you are requesting the website to search through SSL (Secured socket layer) which is the best way for a website to deal with sensitive information like the financial and user information.

When we talk about the SSL means these encryption methods use public and private keys together to create secure connections. Google and other search engines track user data and use the encrypt the information of user’s data.

The Best part is that user’s information is more protected because these search engines like google and other use temporary keys that will expire for security purpose. That means if someone tries to access your information your searches get self-destructed.
