Twitter has warned news agencies including the BBC to improve security following string of high-profile hacking of accounts.
The hacking is reported to have been carried out by a Syrian group Syrian Electronic Army (SEA) with an intent to cause disruption to create support for Syrian President Bashar al-Assad.
Twitter advised in an email to all news organisations to take a close look at their internal measures for addressing social media, such as develop sure passwords of about 20 characters long incorporating random strings of letters and numbers.
The microblogging site advised having just one computer to use for Twitter.
"This helps keep your Twitter password from being spread around," Twitter said.
"Don’t use this computer to read email or surf the web, to reduce the chances of malware infection."
Twitter has been witnessing increasing pressure to bolster its own security, in addition to advising external organisations.
Security professionals have sought two-factor authentication involving two steps, the entry of a password and another action.
Earlier, the hacking group claimed responsibility for Twitter attacks on the Guardian, the BBC, France 24 TV, Associated Press and National Public Radio in the US.
