Twitter is warning some users that they may be the target of security breaches by “state-sponsored actors.”The microblogging service sent emails to an unknown number of users warning that hackers may be trying to obtain phone numbers, email addresses and IP addresses, according to Twitter users who have received the emails. The emails warn that while Twitter is not certain recipients’ personal information was obtained, it has reason to believe they were intended targets.
At this time, we have no evidence they obtained your account information, but we’re actively investigating this matter,” according to Coldhak, a Canada-based nonprofit organization that posted a copy of the letter it received on Twitter. “We wish we had more we could share, but we don’t have any additional information we can provide at this time.”
The emails go on to advise users to take proper precautions to safeguard their personal information, including offering a link to information on Tor, software that allows for anonymous communication on the Internet. Others who tweeted about having received the warning included security researchers and journalists.
A spokesman for San Francisco-based Twitter confirmed the authenticity of the emails but declined to provide further comment.
Social media in particular has become a more popular battlefield for hackers in recent years. The Syrian Electronic Army, a hacking group that supports the regime of Syrian President Bashar al-Assad, has claimed responsibility for several hacks of news sites and company Web sites. The group has hacked into the Twitter account of the parody news site the Onion and it also has gotten into the accounts of the Associated Press , NPR, CBS, the Guardian, and the BBC.
Last month, the hacker collective Anonymous declared war on the Islamic militant group ISIS, saying it wants to steal information from that Web traffic and force ISIS into Internet obscurity. ISIS has used the Internet to recruit new members from around the world and to spread chilling images of executions and other violence.
Not sure about Nigeria, but we need to be extra careful.
