zatko. your testimony and all your responses to the various questions we asked you says to me that the situation regarding data security and national security issues with regards to twitter is massive, that twitter is not doing very much to be helpful at all. in fact, there are major disincentives to twitter doing anything to spending the time or the resources to address the concerns that you raise. for example, the fcc, very under resourced with regard to china to keep twitter under any kind of consent decree entered into back to 2011, more recently they are contemplating making twitter pay $150 million for some misuse of information, 150 milli-dollars --$150 million fine for a multibillion dollars companies nothing for any incentives for them to change what they are doing. and yes, there is information out there from so many different sources, including appliances, cars, and anything else. however, twitter is a huge, if i can call it, single platform to access. who is going to force twitte

zatko: yes, sir. senator graham: if you driver a car you need a license. real estate, you need a license. practice as a lawyer, you need licensed. is there any licensing requirement to run a social media company? mr. zatko: not beyond -- not to the best of my knowledge. senator graham: can you sue a social media company when they do you wrong? mr. zatko: i do not know. senator graham: the answer is no. they are not licensed. you can't sue them. to be shocked you have a problem that's naive on our part. here's what i promise to you, we are going to take your testimony, we are going to learn from it. we are going to create a system more like europe. a regulatory environment with teeth. an agency that came about after 1914, with the power to deal with privacy issues, content moderation, if you want to be in this space you have to harden your sights against foreign interference, you have to protect your sites against criminality, and if somebody takes your content down, you'll have an appeal process outsi

zatko. each member will have six minutes to ask you questions. those of us who are not experts but who rely on the internet every day for personal and professional reasons know that many times we are given disclosures, lengthy disclosures that scroll across the screen which are hardly ever read. they usually end up at the bottom box and that is as far as we go with a warning about what we are getting into. can we get into the real world now and talk about whether or not consumers across america have a right to be warned if they are opening a twitter account as to what is going to happen with their data? for example, if i disclose my name and my address and my email address, i expect that that may be vulnerable, somebody could use that at some future time. i hope not, but it could happen. what i infer from your testimony and what we have read about your findings is that there is a lot more information being collected by twitter beyond that basic information that is going to be used by a handf

and so unsurprisingly, they can't protect it. >> reporter: zatko, who worked for twitter for 14 months before being fired, said the company can't shield users' data from a rogue employee. >> it's not farfetched to say that an employee inside the company could take over the accounts of all of the senators in this room. >> reporter: iowa republican chuck grassley said twitter users were exposed to foreign intelligence agencies. zatko was asked about the fbi informing the company that one suspected chinese agent was on its payroll. >> i'm reminded of one conversation with an executive when i said, i am confident that we have a foreign agent, and their response was, well, since we we already have one, what es it tter i wav >> reporte commi members were astonished by what they heard. >> what i heard there today made we want to throw up. >> reporter: senator grassley said if zatko's claims are true, twitter's ceo, parag agrawal, who refused to appear, should be removed. >> many of the allegations directly implicate mr. agrawal. >> reporter: for zatko, he said it was dangerous coming forward.

zatko was asked about the f.b.i.ming the company that one suspected chinese agent was on its payroll. >> i'm reminded of one conversation with an executive, when i said, "i am confident we have a foreign agent," and their response was, "well, since we already have one, what does it matter if we have more?" >> reporter: committee members were astonished by what they heard. >> what i heard there today made me want to throw up. >> reporter: senator grassley said, if zatko's claims are true, twitter c.e.o. parag agrawal, who refused to appear, should be removed. >> many of the allegations directly implicate mr. agrawal. >> reporter: for zatko, he said it was dangerous coming forward. >> i determined it was necessary to take on the personal and professional risk, to myself, and to my family... of becoming a whistleblower. >> reporter: twitter responded to zatko's allegations, saying that they're riddled with inacuracies and inconsistencies. also today, twitter shareholders approved elon musk's $44 billion bid to buy the c

twitter has said zatko's allegations are inconsistent and inaccurate.now from san francisco, josh constine is a principle investor of signal fire. thank you so much for being with us. >> thank you so much for having me. >> so twitter whistle-blower peiter mudge zatko testified on tuesday laying out his allegations of security failures at the company. the former head of security revealing its weak defenses against hackers and disturbing foreign influencers. he said the company was a decade behind industry security standards, had safety lapses and misled the public. what are the legal and security ramifications of his testimony? >> the fact is that twitter security system is a clown show right now. they are woefully behind the times. they have completely uninstrumented their technology. they don't know who's looking at it. that means engineers have unrestricted access to look at user accounts and private user data. email addresses, phone numbers, i.p. addresses which can give locations. they aren't even aware there are foreign national agents on twitter's

the whistle-blower is peter zatko. in the hacker community, they know him just as mudge he served as twitter's head of security until the company fired him earlier this year. zatko's testimony went beyond what he alleged in the complaint last month to the securities and exchange commission and other regulators he claims twitter's leadership is misleading the public, misleading lawmakers, and misleading regulators. and even its own board of directors. >> what i discovered when i joined twitter was that this enormously influential company was over a decade behind industry security standards. the company's cybersecurity failures make it vulnerable to exploitation, causing real harm to real people >> hearing that testimony, was elon musk. today he tweeted that popcorn emoji as zlatko testified before lawmakers. for context, of course, musk is locked in a legal battle with twitter. trying to pull out of a $44 billion deal to buy the social media company. musk claims twitter didn't give him all the data he requested, about f

you have the former security chief pieter zatko talking to a senate panel.e are watching this with a great deal of interest. i would have thought that somebody else is watching it even more closely. alix: mr. musk, i would say he is very much watching this to help his case that he would be let out of the twitter deal. we know that he said that executives focused on profits over security. he has said that in the past as well. he said the ftc is in over its head and this is as the ftc tries to explain claims to the senate panel. he also goes to say preemptively that he does not make any disclosures out of spite because he was fired due to poor performance. guy: senator grassley calling for a ceo magic nate -- resignation. you almost never see that. what was interesting is that he was invited but he declined to come to the meeting or the hearing. so, it is getting feisty. as you say elon musk is paying a great deal of attention to what is happening. this in some ways goes to the heart of what we are talking about in terms of the twitter case. ed will join us la

zatko is known by the hacker name mudge. he was fired by twitter in january of this year after working there for a little over two years. [inaudible conversations] [inaudible conversations] >> this meeting of the senate judiciary committee will come to order. in 2006, the new social networking platform marked its debut when jack dorsey posted a message that he was just setting up my twitter. at the time dorsey's startup which allowed users to share short messages was a novelty but in the coming years it would become increasingly a source of news and social discourse as it gathered millions of users around the world. twitter now plays an outsized role in politics, culture and even democracy itself. as twitter has grown, so the risk posed by bad actors looking to exploit its opportunities in the data it holds. in july 2020, two teenagers hacked into the accounts of twitter employees gaining access to a number of high-profile accounts including now president biden and former president obama. those two teenagers then sent a seri

zatko.> let the record reflect the witness has answered in the affirmative and now i appreciate your attendance here and the floor is yours i think your microphone may need - >> all right thank you very much, sir chairman durbin, ranking member grassley, members of the committee, i appear before you today to answer questions about information i submitted in written disclosures about cyber security concerns i observed while working at twitter my name is peiter zatko but i'm more often referred to as my online handle as mudge for 30 years my mission has been to make the world better by making it more secure. from november 2020 until january 2022, i was a member of twitter's executive team in my role, i was responsible for information security, privacy engineering, physical security, information technology and twitter global support i'm here today because twitter leadership is misleading the public, lawmakers, regulators and even its own board of directors. what i discovered when i joined twitt

former twitter employee turned whistleblower peter zatko. >> who recently outlined security flaws of the company that he says put millions of users at risk. now musk is using those claims, we mentioned help and get out of the twitter deal. most recently filed paperwork with the securities and exchange commission saying the whistleblower's revelations give him more reasons to terminate the deal. and today as kron four's anna wiernicki reports that high profile whistleblower testified before congress about his bombshell allegations. >> twitter's former head of security peter zatko told lawmakers that for years the social media company prioritized profit over protecting its users. they don't know what data they have, where it lives or where it came from. and so unsurprisingly, they can't protected. sacco was fired from twitter earlier this year for what they called, quote, ineffective leadership and poor performance. >> then last month is filed a whistleblower complaint with the ftc complaining that the company ignored major security twitter doesn't just have access to your tweets and m

zatko. i wouldn't automatically recoil at the $7 million number. we need to find out what that is about. i doubt we will learn that tomorrow. emily: how are you expecting this testimony from zatko tomorrow to be folded into the case that of course was building up to this trial coming up in mid october? >> is -- his testimony tomorrow about the national security staff and potential spies within twitter's employee group are the things the senators will be focusing on. the focus we are concerned about is going to be his allegation about spam and robot accounts invented within the customer base. and twitter, his colleague's lack of interest in finding that out. that is the key question in the trial coming up, because that is where mr. musk has put all of his ships in terms of defense arguments. emily: clearly, both parties will be watching this testimony with bated breath. any word from twitter about the latest, how this potentially changes their plans? >> they basically came up and said we do not buy the argument that the separation agreement is a via

thank you mister zatko. following up on that point i returned from ukraine where senator portman and i saw firsthand the extent of the damage inflicted by the russian invasion. i was troubled to learn according to your written disclosures twitter's leadership recently considered agreeing to the putin regime's request to sensor and survey of russian twitter users . twitter ultimately did not agree to putin's request as far as i understand. what can you tell us about requests made by foreign governments and the rest of those commands posed . and why would a company like twitter consider the request to survey of users. >> i was surprised and shocked by that one on one conversation i had which i had with mister vanderbilt prior to his assuming the ceo role. i understand it's out of the frustration of the inability to perform and this kind of goes into content moderation which we talked about before and while that wasn't my main element and i've been informed i shouldn't go into detail of the conversations i've h

there are clearly conflicts between zatko and peraga. think with security, it is a hard topic because despite the political table pounding, the reality is nuanced. twitter has had a few high-profile hacks but they are not a regular occurrence. every day without a hack is a success. there is no prize for a day without breaches. could most companies do more to improve security? certainly. does twitter do security better than most companies? most certainly. emily: what were your big takeaways about the big revelations here? and what this might actually mean for its dispute with elon musk given that it did not seem like bots and spam really came up. >> i will start with the takeaways that are not ask related and related to what adam was saying. there was a lot of political table pounding and a lot of calls for increased enforcement, increased regulation. and emily, there were surprising allies. folks like lindsey graham the republican from south carolina aligning with elizabeth warren, the democrat from massachusetts saying we are working on

twitter denies the allegations say that zatko had presented a quote. >> false narrative.today, twitter shareholders voted to hold elan musk to his 44 billion dollar deal to acquire the company. he is currently suing to get out of that deal. and a trial is set for this fall. >> coming up, police say they finally identify some human remains found near an apartment complex on the peninsula. details how a 3 year missing person investigation turned into a tragedy and a little close for comfort. a mountain lion takes a stroll close to a home on the peninsula. we're going to show you the video and the body of queen elizabeth. the second is now in london. we'll second is now in london. we'll have a live report from ♪ ♪ this is how it feels to du more with less asthma... ...thanks to dupixent. dupixent is not for sudden breathing problems. it's an add-on treatment for specific types of moderate-to-severe asthma. and can help improve lung function for better breathing in as little as two weeks. dupixent helps prevent asthma attacks... and can even reduce or eliminate oral steroids.

and what zatko is alleging here is that too many of twitter employees have access to some of the company's, maybe a foreign agent to go into the company and take control of those accounts. you think about how much politicians, how much public figures use social media platforms. decorations from president's prime ministers, how potentially damaging and dangerous that is. twitter, for its part, said that mudge, the whistleblower is exaggerating the issue that it fixed a lot of problems. we're staill waiting for a response on the alleged chinese spy at the company. >> to be clear, is he saying that the foreign countries, kl china included, do they have a sleeper and they could take over anyone's account. >> what he said a few minutes ago that the access in twitter so to broad that foreign intelligence agencies would not be doing their job right if they weren't getting people into this company. trying to access these accounts anz access to all sorts of information. >> remarkable revelations. donie o'sullivan, thank you so much for covering. >> >>> king charles and the queen consort are in belf

and, frankly, at the very serious security issues that peiter zatko has raised relative to twitter. >in what you mean when you're talking about it. obviously, you've joined us talking about a range of issues through the years that senators and congressmen have talked to various people at hearings about. >> so, zatko is a famous white knight hacker who was hired by twitter to be the head of security and he didn't last very long in the end, he was fired but, according to materials that he's released to the s.e.c., twitter has violated its 2011 consent decree with the federal trade commission and committed a series of really serious security offenses. i mean, business practices that would be unacceptable anywhere, but particularly to a company that has the level of import that twitter has as twitter is the most important platform for politicians, for celebrities and for journalists. as a consequence, be one has a right to expect that they will take at least industry standard security precautions what zatko is pointing out is they may have had industry worst implementation of their securi

reporter: twitter fired zatko.ver its head when it is regulating twitter. the firm doesn't care about user safety, just making money. >> to put it bluntly twitter leadership ignored its engineers because key parts of leadership lacked the competency to understand the scope of the problem but more importantly, their executive incentives led them to prioritize profits over security. >> in his opening remarks gop iowa senator chuck grassley said at least one chinese agent works for twitter. zatko says it would be easy for foreign intelligence firms to install agents inside of twitter to track everyone. sat cosays twitter is unwilling to root out potential spice to could compromise national security. >> i'm reminded of one conversation with a executive when i said i am confident that we have a foreign agent. their response was since we already have one what does it matter if we have more. let's keep growing the office. reporter: twitter declined to comment on the hearing and testimony from zatko. later twitter announce

i would like your reaction to this, twitter is calling zatko's events.ter leadership is misleading the public lawmakers regulators, and even its own board of directors. the company's cybersecurity failures make it vulnerable to exploitation, causing real harm to real people. when an influential media platform can be compromised by teenagers, thieves and spies and the company repeatedly creates security problems on their own this is a big deal for all of us. >> 4,000ish employees would have had access to live user data all over twitter. >> we've learned that personal data from twitter users was potentially exposed to foreign intelligence agencies. india was able to place at least two suspect foreign assets within twitter. fbi notified twitter of at least one chinese agent, in the country. the company i should say. >> will, okay, you heard that, right, will? thousands of twitter workers can find out user's exact location every day, maybe docks dox who knows? chinese foreign agents work at twitter behind the scenes? >> it is shocking, but it is not simply a

we hear in person from peiter zatko. he goes by the nickname mudge. mis misleading communications with board members and users and shareholders of twitter. he focused on four main crit criticisms lack of software security and too much access to sensitive data by employees. internal process issues and security issues impacting user data the biggest issue is misleading the board about the problems at the company. the dramatic testimony we expect before the senate judiciary committee today comes against the back drop for struggle of the company with elon musk looking to get out of the $44 billion acquisition attempt. twitter looked to minimize the zatko allegations and saying he was terminated for poor performance. they call the allegations a false narrative. musk is looking to get out of the company and changed his mind we can expect mudge to be asked about the settlement twitter paid him $7 million in june over lost compensation. he signed a nondisclosure agreement at that time whistleblower complaints and testimony are exceptions to the agreement. he

that charge was backed up by twitter whistle—blower and former head of security, peter zatko, who claimedd to count bots as people. this all comes down to how twitter actually counts its bots and it is way less techy their chief executive parag agrawal described in a tweet how they do this: "our estimate is based on multiple human reviews". elon musk says that is totally unscientific. and yet the creator and maintainer of botometer, the tool that elon musk is using thinks that twitter�*s methodology actually isn't that bad. if i were the people in twitter i would probably be doing something similar. it is still to me how they define those things. it is not clear. if they really want to do this, they can sit together so we can say oh, can we agree on this account is a bot, this account is a human. but twitter and elon musk aren't sitting down together, they simply cannot agree how many bots twitter has, and that is the fundamental problem — perhaps no—one can. that was james. so i have been at the edinburgh fringe festival to find out how tiktok is giving a new type of comedian a chance to

but more importantly, their executive incentives led them to prioritize profits over security >> zatko also saying twitter repeatedly violated the 2011 consent decree and said the ftc is over its head letting the tech companies including twitter grade their own home work. also raising concerns about foreign agents, government spies being hired by twitter, saying the company doesn't have the technology to identify inappropriate access to data within twitter systems and when he flagged concerns about foreign agents at the company management didn't want to do anything about it. he also talked about chinese government entities advertising on the platform, and he said the company didn't know what data they were giving the chinese entities so it has been really interesting to hear this conversation about the failure of u.s. regulators, both in terms of legislation and also funding to the agencies like the ftc. they said that mudge said twitter was a lot more concerned about foreign regulators than those in the u.s one thing he hasn't talked about yet which is very much relevant to the coming

peiter "mudge" zatko told lawmakers that china and india had agents working inside twitter and that the company's security protocols were inadequate. >> what i discovered was that this enormously influential company was over a decade behind industry security standards. the company's cybersecurity failures make it vulnerable to exultation, causing real harm to real people. and when an influential media platform can be compromised by teenagers, thieves, and spies and the company creates secretive problems on their own, this is a big deal for all of us. amy: the right-wing conspiracy theorist alex jones is on trial again, this time in connecticut, for claiming the 2012 sandy hook mass shooting was a hoax. last a month, a jury in texas ordered jones to pay nearly $50 million to a sandy hook family. now a jury is hearing a case brought by 13 family members of victims and an fbi agent who accused jones of defamation. and former independent counsel ken starr has died at the age of 76. in the 1990's, the right-wing judge headed an investigation of president bill clinton that led to clinton's im

emily: twitter's peiter zatko, but he had to say about twitter's board is not very flattering at theearing, sing when presented with security concerns, twitters boards it did nothing. does that make bret taylor look unfavorable? >> i don't think so. the way that he has viewed this is through a phrase he has defined to twitter employees many times. he has said that my job here is to get the best deal i can. what's interesting is this is somebody who has managed to come out of every situation looking like he got a good deal, looking like he was a good business player. with twitter he may have found himself in a no win situation. if he succeeds in court in october, he sold the company to someone who doesn't want the company. even if he settles, the company has been through the ringer and will probably get sued by shareholders. it's going to be a tough situation for the board and for bret taylor. emily: really interesting profile you did. bret taylor. you can read more of brody's story on bloomberg.com. we'll hear from a top executive from amazon and a downturn from another side of the w
