Sounds familiar? This is Social Engineering in a nutshell. Though the term has no affinity towards the good side of engineering and being social, it is primarily anti-social and destructive in nature.Social engineering is the process of manipulating human mind to spill confidential and personal information. This is a well formulated attack crafted by criminals or hackers to trick people into giving away vital information like passwords, bank information and etc. Apart from pulling data, the hacker also forces the gullible user to install a malicious bug and siphons out the necessary information without the user‘s realization. This is smart engineering wherein users release passwords on their own rather than being hacked.
Types of Social Engineering attacks: Tapping people for details
Hacker interacts with people and gets the necessary details. This can happen in any of the following ways:
- Pretending as a valid user of the system, the hacker accesses physically in the form of a helpful desk operator whose disguise is difficult to misinterpret, since they are designated to help employees.
- An over enthusiastic colleague could also impersonate and gain access to other’s systems, on the pretext of solving a problem.
- The hacker can also pretend to be a technical support staff from the organization’s vendor, explaining that he is troubleshooting a particular issue which will require the user to share the ID and password to resolve the problem. Gullible employees can fall trap to such requests if they are not alert.
- Employees can also become victims if they leave important passwords and file names in pieces of paper or printouts and leave it unnoticed, to pave way to the hands of the hacker.
Gaining access indirectly, through computers
Messages that mimic or spoof banks, credit cards or other online purchasing companies like Amazon, ebay are examples of phishing. Asking to verify information, false emails, chats are different ways to capture confidential information. The process is made to look so real, that users when not alert become easy prey for such mails.
A free download of a movie or a music file embedded with a malicious code is an easy access for a hacker to target and obtain specific information. This happens with the victim’s system being infected with malicious software facilitating the hacker to approach deeper into the system.
On-line scams –
Pop-up windows flashing advertisements tempt victims to download or install virus loaded software without them realizing. Trojan worms, viruses and capturing passwords form an integral part of the hacker’s schedule to infect other systems. In addition baits are laid in social media platforms to share information, job portals to name a few.
How to protect yourself from potential attacks?
- Beware of common tricks played by hackers.
- Think twice before sharing confidential information.
