What Is Shylock Malware and How Does It Function

   Shylock is a family of malwares that depends on browser man - in  - the -  middle attacks . Man – the – middle attacks by which the attacker clandestinely relays and possibly changes the communications between two parties who think that they are communicating with each other. It uses digital certificates that have been faked so that it can head off  and place in codes into banking websites. It was created to fool customers so that they can give banking details to hackers instead to the customer service of the bank. There are some types of this malware that have capabilities of opening fake customer chat windows on computers that have been compromised. This allows cyber attackers to get pertinent information from their accounts. Newer strains of this malware have the capability to find out whether the malware is running on a virtual machine that is being examined by malware researchers. This way  the Shylock malware becomes more difficult to analyze and it does avoid being detected by security researchers.

   It is not as popular as other malwares but it does not make it less dangerous. It has a set of malicious methods that it uses because it is able to inject in it’s body multiple running processes, it has the necessary equipment to stop it from being detected by anti -malware software. It uses a number of plugins which adds additional malicious functions aimed at bypassing anti - malware software. It gathers passwords for FTP ( File Transfer Protocol ) servers. It spreads by using messengers and servers. It supplies remote access to the compromised machines. It can do video grabbing and web injection, Injection is an entire class of attacks that depends on injecting data into a web application in order to further expedite the execution of malicious data in an unforeseen manner. The last objective is to steal online banking credentials by placing in fake data entry fields into the web page loaded in the victim’s browser.

What Is Zeus Malware and How Does It Work

   Zeus Malware also known as Zbot Trojan Horse malware aims at infecting Windows OS. It can be used as a carrier of a lot of malicious criminal activities. Mainly this malware is used to steal banking and confidential information from the infected computer. The Zeus malware was created to steal private information from computers that have been jeopardized. The toolkit for this is available on the web and it can found on sites where cyber criminals go to. Usually you get this type of malware from emails that try to deceive you to open a file. The file may seem legal because it looks like you are being sent messages from Microsoft, Facebook or the IRS. The email will usually issue you a notification on your online account or tell you that you have an underlining concern regarding financial or banking information.
   Private information can be collected in several ways. When it has been enforced the Zeus Malware will naturally collect Internet Explorer, FTP ( File Transfer Protocol ) or POP3 (  Post Office Protocol3 ) passwords. The most potent harmful effect it can create is by tracking down the websites in the configuration files. It can take hold of all legitimate web pages and place in extra fields. ( for example  it can add additional information into a banking Web page which initially only asked for your username and password ), This can cause havoc and real concerns on your part.
   
    Zeus Malware works by modifying your configuration files that have been well organized into the Trojan installer by the cyber criminal. It can also be updated by the attacker to hit your other information at any time. This kind of malware gets in contact with a command and control server and it can make it do other different kinds of tasks. Doing this, will permit the cyber criminal to direct the malware to download and enforce other actions. It can shutdown your computer and reboot it. Your system files can be deleted. You cannot use your computer without reinstalling the Windows Operating System.

What is Industroyer and How Does It Attack Power Grids

   The Win32/ Industroyer malware is an innovative type of malware that was created to interrupt and distort working procedures of  Individual Control Systems. More specifically it was designed to disrupt Industrial Control Systems that are used in electrical substations. Those that are behind the   Win32/ Industroyer have a clear understanding and a lot of expertise in Industrial Control Systems. They have a deep understanding of industrial protocols used in electric power systems. Industroyer is an advanced malware that has many components like a backdoor, a data wiper, at least 4 payloads and many other tools. These cyber attackers are experienced  analysts  and they know all the payloads involved ( IEC 60870 - 5 -101 ( aka IEC 101 ), IEC 60870 - 5 - 104 ( aka IEC 104 ), IEC 61850 OLE for Process Control Data Access ( OPC DA ). These are the central elements used in the attacks and it allows them to control electrical circuit breakers.
   The Industroyer backdoors gives these cyber attackers the right to engineer several commands on targeted systems. The C&C S is concealed in the Tor network. It can be set up to be active at a specific time. This makes it hard to detect. The backdoor sets up the launcher element which starts the wiper and payloads. It also puts down a second backdoor that camouflages itself like a trojanized form of the Windows Notepad application. The wiper element is used in the last stage of attack to conceal tracks and make it hard to restore the targeted system.
   Cyber crimes are meant to earn money and this can be done by ransomware , banking trojans, spam, unwanted ads and identity theft. This kind of malware is not meant for earning money. Their main objective here is to damage targeted facilities.

What Is Bitcoin Mining And How Is It Done

   Bitcoin Mining is a procedure by which transactions are confirmed and then they are added to a block chain and this is a way wherein new bitcoins are released. Any individual who has a computer and access to the internet  plus the right hardware can do bitcoin mining. You need to compile recently done transactions into blocks and then try to solve difficult computational puzzles. The first one to do so gets the opportunity to place the next block on the block chain and then you can get your rewards, usually in bitcoins. The rewards are the transaction fees that are connected with the transactions that have been assembled in the block and also the newly released bitcoins.

    Blocks are chained together and it is continuous, this is called a  block chain.  This way there is no conflicting transactions. This way there would be no bad transactions. This is an assurance that people will not be able to sign the same bitcoins to two different people. Bitcoin makes sure that blocks are hard to produce and they do this by making only one block chain. This way, miners will have to compute a cryptographic hash that has a certain criteria. This is what they call hashing. Hash is a function that takes an input ( message ) and returns a fixed – sized alphanumeric string. The string is known as the hash value or message digest. The only way to find a cryptographic hash that is suffice so that the miners can count and  try computing a cluster of them until you find one that works. This is the way wherein miners are rewarded some bitcoins and it has a preset schedule. It becomes hard because the hash are adjusted often and this is based on how frequently blocks do appear. When there is more competition , there is more work that has to be done in order to find a block. You need an up to date GPU ( Graphics Processing Unit ). You need this in order to competitive. There are millions of hashes per second and a newer GPU can be very helpful in finding hashes. Without having a specialized hardware the job would be difficult and the miner would have to spend a lot. All miners must be able to validate all of their or else they won’t receive their rewards. The job of finding blocks is so intensive  and it is only through hashing that the network is secured.

What Is Blockchain and How Does It Work

   Blockchain is a public ledger of all bitcoin negotiations that have been accomplished. The growth becomes continuous when additional blocks are added on.  After that a brand new set of recordings are made. The blocks are added onto the blockchain in a linear and sequential manner. Each node ( a computer that  is linked up with the Bitcoin network wherein the client does the job of validating and disseminating transactions ) receives a copy of the blockchain. It automatically will be downloaded when the person joins the bitcoin network. The blockchain has all the information needed by the client. This includes balances and addresses from the time that the client started with the bitcoin network ( starting block ) until his most latest finished block. Blocks are like the bank statements issued by the banks.
    Blockchain allows two entities ( persons  ) who do not know each other come to an agreement without using a third party. Because blockchain is decentralized, open and cryptographic, this process allows two entities to trust each other. Blockchain is a kind of distributed ledger that has a decentralized database which keeps all records of digital transactions. Blockchain gets a number of inputs and puts them into blocks. Each block now is chained ( connected  ) together. This is done using a cryptographic signature. It now becomes a ledger that is accessible to any person who has permission to do so. Blockchains are good because it does give clients some sort of protection and benefits. It would be very difficult for cybercriminals to hack into because they will need to hack all the blocks that have been formed. The hacker would have to hack all the blocks from beginning to your last transaction. They would have to do it from the beginning ledger till the last ledger. There can be thousands of ledgers that have to be hacked. This makes it virtually impossible to do so.

What Is Ethical Hacking All About

   In order to perform ethical hacking, you need to be known as an ethical hacker.  The ethical hacker will hack into a computer network and will make a probe exploration and assess it’s security with the knowledge of it’s owners. The ethical hacker will find out the weaknesses of the security system that any hacker can take advantage of.
   Ethical hackers do use the same methods as criminal cyber hackers do.  Their main intent is to determine any faults on the security system and find out if the system can be penetrated by illegal access and malicious activities. Computers that are open to attacks have sub-standard configuration systems, well acknowledged hardware and unfamiliar hardware. Their systems may have software flaws. Ethical hackers may also find out if your system network may have operational deficiencies. Any organization or company whose computers have access to the internet or are engaged in online services should undergo penetration testing . Penetration testing means testing computers that are on a system, network or application so that faults could be found  and avert attacks from cyberhackers. Penetration testing is also known as Ethical Hacking.
   
Ethical Hackers Must Follow Rules:

1.  Ethical hackers must have written permission to investigate and try to identify possible security risks.

2.  Ethical hackers must have high respect for any individual or company’s  privacy.

3. Ethical hackers must make sure that when they are finished doing their jobs, there is no loopholes for any criminal cyberhacker can exploit.

4.   Ethical hackers must make known to the software or hardware developer of the faults that you have found.

5. Ethical hackers must record their findings.
