NEW DELHI: The official web portal of the Indian Revenue Service (IRS) was allegedly hacked by a suspected group of Pakistan-based hackers, Indian media alleged today.

According to Indian officials, the website which belonged to India’s Income Tax department, was hacked early Saturday and still remains offline.

Officials further claimed that messages, which read, ‘Pakistan Zindabad’ and ‘We are team Pak cyber attacker,’ were posted on the website.
