COMMON ATTACKS DONE ON INDIVIDUAL LEVEL:

• Malware Attack: Malware, or malicious software, is any program or file that is harmful to a computer user. Malware includes computer viruses, worms, Trojan horses and spyware. These malicious programs can perform a variety of functions, including stealing, encrypting or deleting sensitive data, altering or hijacking core computing functions and monitoring users' computer activity without their permission.
• Phishing Attack: Phishing is a method of trying to gather personal information using deceptive e-mails and websites.
• Password Cracking: Password cracking refers to various measures used to discover computer passwords. This is usually accomplished by recovering passwords from data stored in, or transported from, a computer system. Password cracking is done by either repeatedly guessing the password, usually through a computer algorithm in which the computer tries numerous combinations until the password is successfully discovered.
• Social Engineering: Social engineering is the art of manipulating users of a computing system into revealing confidential information that can be used to gain unauthorized access to a computer system. The term can also include activities such as exploiting human kindness, greed, and curiosity to gain access to restricted access buildings or getting the users to installing backdoor software. Malware Attack & Phishing Attack are also type of Social Engineering.

 
COUNTERMEASURES:

• Malware Attack:

1. Installing Anti Malware Applications/Software.
2. Regularly get the Data/Drive scanned and analyzed.

4. Scanning the unknown links on virustotal.com . It gives the exact report of testing performed on that particular link by all the Anti-malware/Anti-virus.

 

• Password Cracking:

1. Change all the default passwords on each new and existing devices/Systems. For Eg: Wi-fi Routers , CCTV , etc.
2. Never use Same passwords for privileged user accounts between systems.
