BE AWARE OF FaKe Call

Phishing is defined as any attempt to obtain your personal and financial information. Mostly, phishing is carried out via emails. These emails lure the targeted victim into visiting a fake site and giving away confidential data. Phishing attacks also use fake SMSs (called Smishing) and fake telephone calls (called Vishing).
What we are discussing here is related to vishing, also known as voice phishing. Several instances have occurred wherein people receive phone calls that appear to be from their bank. The caller usually pretends to be a bank representative or someone from the bank’s technical team. In most cases, the caller sounds professional and provides a convincing reason for calling the customer. After having given a false sense of security, the caller then tricks the victim into giving away their personal and confidential data such as:
  • Credit/debit card number
  • The card’s CVV number [Card Verification Value – 3 to 4 digit number printed on the flip side of the card]
  • Expiry date
  • Secure password
  • ATM pin
  • Internet Banking login ID and password and other personal information
With all such crucial information at hand, the fraudster can easily carry out illegal financial transactions using the victim’s name.
Real Case Scenario
One of our readers had encountered a similar situation. The reader received a call that seemed to be from their bank’s customer service center. The caller was able to convince our readers that their bank account and ATM card is in the process of getting upgraded and updated. And for that, the following details were required:
  1. ATM cum debit card number
  2. CVV number
  3. Expiry date
  4. Password
  5. Savings bank account number
Later, our reader came to know about several unauthorized transactions that were made using their bank account, which amounted to a sum of ₹ 65000.
How you can protect yourself from such phone scams
Below is a list of safe banking tips that banks such as SBI, ICICI, HDFC, and others have issued for their customers.
1. Banks or any of their representatives never send customers email/SMS or call them over the phone to ask for personal information, password or one time SMS (high security) password. Any such e-mail/SMS or phone call is an attempt to fraudulently withdraw money from the customer’s account through Internet Banking. Never respond to such email/SMS or phone call.
2. Never respond to emails/embedded links/calls asking you to update or verify User ID/Password/Debit Card Number/PIN/CVV, etc. Inform your bank about such email/SMS or phone call. Immediately change your passwords if you have accidentally revealed your credentials.
3. Do not provide any personal or confidential information on a page which might have come up as a pop-up window.
4. Always remember that information like password, PIN, TIN, etc., are strictly confidential and are not known even to employees/service personnel of the bank. You should, therefore, never divulge such information even if asked for.
5. Never provide your identity proof to anyone without any genuine reason.
6. Never click on any links in an e-mail to access the bank’s site.
7. Access your bank website only by typing the URL in address bar of the browser.
8. Do not provide your bank account details to emails offering a job or claiming that you have won a lottery. Avoid opening attachment of emails from unknown senders.
10. Having the following will improve your online banking security:
  • Newer version of Operating System with latest security patches
  • Latest version of browsers
  • Active Firewall protection
  • Up-to-date antivirus software
11. Avoid accessing Internet banking accounts from cyber cafes or shared PCs.
12. When on your bank website, look for the padlock symbol either in the address bar or the status bar (mostly in the address bar) but not within the web page display area. Verify the security certificate by clicking on the padlock.
To conclude with one last security tip for safe online banking, avoid accessing your Internet banking accounts from cyber cafes or PCs used by multiple people.

Top Five Questions and Answers

Top Five Questions and Answers

1. Differentiate User Mode from Privileged Mode
A. User Mode is used for regular task when using a CISCO router, such as to view system information, connecting to remote devices, and checking the status of the router. On the other hand, privileged mode includes all options that are available for User Mode, plus more. You can use this mode in order to make configurations on the router, including making tests and debugging.
2. What is 100BaseFX?
A. This is Ethernet that makes use of fiber optic cable as the main transmission medium. The 100 stands for 100Mbps, which is the data speed.
3. Differentiate full-duplex from half-duplex.
A. In full-duplex, both the transmitting device and the receiving device can communicate simultaneously, that is, both can be transmitting and receiving at the same time. In the case of half-duplex, a device cannot receive while it is transmitting, and vice versa.
4. What is MTU?
A. MTU stands for Maximum Transmission Unit. It refers to the maximum packet size that can be sent out onto the data line without the need to fragment it.
5. What is latency?
A. Latency is the amount of time delay that measures the point from which a network device receives a data frame to the time it sends it out again towards another network segment.

What causes CRC errors?

What causes CRC errors?

A. Cisco networking CRC errors are generally a layer 1 issue caused by a faulty port on the device or bad Ethernet cable. Changing the cable or swapping the port is a relatively easy fix. Occasionally they are generated on layer 2 by a duplex mismatch. This happens when the port on one device is set for full-duplex and the port on the connected peer device is set for half-duplex.
The ports can be compared by using the show interface command on both devices.
In TDM networks, there are many problems that cause CRC errors. They include faulty wiring or cross-connects, bad repeater cards, flakey smart jacks, or bad cable and channel cards. Isolating the cause of these errors usually requires the telecommunications provider to conduct loopback testing or to dispatch a field engineer to the site to test head-to-head with the central office.
