Chief Superintendent of Central Telegraph Office (CTO) Kolkata, Subrata Kumar Das shows a part of the old Telegraph machine at the Central Telegraph Office in Kolkata on July 14, 2013. After 162 years of connecting people, India is now set to disband the world's last major telegram service and its legions of cycle-borne delivery workers.

This is currently a unique method since most cyber attackers prefer to use advanced systems since companies and agencies are integrating enhanced security features into their software and other products. 

Since the Morse code is a new efficient hacking or phishing tactic, Microsoft said it had conducted a year-long investigation on the new invoice-themed XLS.HTML phishing campaign. 

Microsoft said it discovered that the hackers behind the new phishing method change their encryption and obfuscation mechanisms every 37 days, which is regularly conducted. This means that their new tactic is efficient in constantly evading detecting and keeping the credential theft operation running. 

"This phishing campaign exemplifies the modern email threat: sophisticated, evasive, and relentlessly evolving," added the search engine giant.
