- Congress deactivated the twitter accounts of 200 leaders
- The accounts were deactivated due to "suspicious activity"
- The accounts of Rahul Gandhi and Congress were hacked on Wednesday
Sources say Congress leaders have been asked to change their passwords and "a full review" is being carried out after the hacking.
Congress spokesperson Randeep Surjewala told NDTV that Mr Gandhi's Twitter handle @OfficeOfRG, his email account, the Congress Twitter account, the party's website and internal server were all hacked between 9.30 pm on Wednesday and 10 am today.
This evening, sources say, leaders on the Congress server were asked to close their accounts or not use them until there is a detailed security assessment over the next few days.
Rahul Gandhi's Twitter account was the first to be hacked and bombarded with abusive tweets full of racist and homophobic slur. The hackers removed his profile picture and changed the title from @OfficeOfRG to "Retarded Gandhi".
To every one of you haters out there. I love all of you. You're beautiful. Your hatred just doesn't let you see it yet- Office of RG (@OfficeOfRG) December 1, 2016
The Congress number 2's account was "compromised through an email breach", sources in Twitter India said.
Hours later, a dozen abusive tweets emerged on Congress's @INCIndia's account. One of them threatened to post a "full dump" of hacked emails.
One of the tweets posted by the hacker threatened to dump emails of the Congress party.
The government has started an investigation and asked for details of users who have logged on to the accounts in the past week.
"As soon as I heard it last night, I spoke to the IT person in charge," Minister Ravi Shankar Prasad told reporters.
The Congress has alleged that the attack was by "licensed trolls" and reflected "disturbing insecurities of prevalent fascist culture". The party, however, was asked not to "make a big issue" of the hacking in parliament by Mr Gandhi.
