Tech companies are facing a growing backlash after their chat software became infected with a malicious piece of malware.
The malware was first reported by The Verge on Wednesday and has been circulating on social media for the past few days.
The Verge reported that the malware has been used by a hacker group called CyberGhost and other groups.
The group claimed to be behind the hack, which targeted the social networking site Twitter and other sites that used the company’s ChatSecure.
The hacker group said that it had also sent spam messages to hundreds of millions of people, and that the hackers had used the botnet to spread malware through email accounts, Facebook and other platforms.
“It is the largest cyber-attack on the internet since the election,” said Chris Wysopal, chief technology officer at CrowdStrike, in a statement to The Verge.
“We believe the attackers are still active and are targeting multiple companies including Microsoft, Twitter, Adobe, Adobe Systems, Google, Intel, Microsoft’s Cloud Platform, Facebook, Twitter’s own servers, and other large companies.”
Facebook said on Thursday that it was working with its social media team to “protect our users from this malicious threat.”
“We have taken action to identify this threat and will continue to monitor the situation closely,” a spokesperson told The Verge in an email.
The cyberattack on Facebook came just hours after a hacker claimed to have hacked into the personal data of over 100 million Facebook users.
Facebook’s response to the attack, which the company said occurred between Tuesday and Wednesday, came as the social media giant faced criticism for the way it handled the situation.
In a post to its Facebook Community page on Wednesday, Facebook CEO Mark Zuckerberg said that the company was working to “provide an uninterrupted user experience” to users who are impacted by the malicious botnet attack.
He also said that Facebook would offer “support services for people affected by this attack.”
However, on Thursday, Facebook told Business Insider that it has not responded to the attacks, and it does not plan to do so.
“Unfortunately, we don’t have any immediate plans to update the site to address the situation,” a company spokesperson told Business Insider.
“Our team is working to determine what happened.
We will provide updates when we have more information.”
In addition to Facebook, several other social media companies have also reported receiving malicious botnets.
On Thursday, Twitter said it was also experiencing issues with a botnet that is currently active.
The botnet, dubbed “Hackers Anonymous,” was identified on Wednesday as belonging to a Russian group called Pawn Storm.
Pawn Riot’s website said that its “most notable attacks” have targeted governments, law enforcement agencies and the military.
According to Twitter’s statement to Business Insider, Pawn Raid has also been using the bot network to spread spam messages, including those targeting government agencies, the U.S. military and other entities.
“These botnet-controlled attacks are being deployed by our Pawn-controlled botnet operators, including the Russian-speaking PawnStorm,” Twitter said in a separate statement.
“All the data, including passwords, has been compromised and has not been used for any purpose.
We are actively working to restore the sites to a healthy state, including by re-authenticating users and removing spam from the system.”
Twitter has not yet provided any further details on how the company plans to prevent a repeat of the botnets infection.
“As a result of the Pawn raid botnet we are now in the process of shutting down our internal systems,” a Twitter spokesperson told B2BInsider.
