While Zoom is being sought after by users, various privacy and security concerns are also in the spotlight. From built-in attention-tracking to recent Zoomombing,” where spoilers can easily enter meetings held on Zoom and share inappropriate content, causing meetings to be terminated), and the company faces at least three lawsuits.

Themedia CNET took stock of news reports about the Zoom security incident and rearranged it according to the time of the incident.

For a larger deployment of end-to-end encryption, Zoom announced in a blog post Thursday that it had acquired Keybase, a security messaging and file-sharing service. Zoom said Keybase will make an important contribution to Zoom’s 90-day program to enhance security and privacy on the platform. Keybase co-founder Max Krohn will lead Zoom’s security engineering team, reporting directly to Zoom founder and CEO Eric Yuan.

Founded in 2014, Keybase is dedicated to the study of end-to-end encryption and currently employs 25 people. Although Zoom’s recently released version 5.0 supports encrypting content to the industry standard AES-265, the post says the company will provide an end-to-end encrypted conferencing model for all paid accounts in the future. In the post, Zoom also said details of the new encryption design would be released on May 22.

“We will then hold discussions with civil society, encryption experts and customers to share more details and solicit feedback,” Zoom wrote in the post. Once we have evaluated this feedback to integrate into the final design, we will announce our engineering milestones and objectives for deployment to Zoom users. “

In response to the ongoing Zoomombing incident, the company said it would address the issue by strengthening the reporting mechanism for conference moderators and attendees, as well as using automated tools to find evidence of abusive users. Zoom said it would not develop any tools that law enforcement could use to decrypt the contents of the meeting, nor would it create any encrypted backdoors to keep the meeting under secret control.

According to a federal intelligence analysis obtained by ABC News, Zoom is vulnerable to foreign government spy agency. According to reports, the U.S. Department of Homeland Security’s Cyber mission and counter-espionage mission center released an analysis has been distributed to governments and law enforcement agencies across the country.

The report says security updates to the software may not be effective because malicious actors may exploit delays and develop vulnerabilities based on vulnerabilities and available patches. A spokesman for Zoom said there was serious misinformation about the report.

The Zoomombing incident continues to fester, including child abuse.

In recent reports, abusive pornography has emerged in academic and government meetings, which witnesses described as including racist language and child pornography images.

Students at Fresno State University and Bakersfield College were exposed to child pornography in two incidents reported Monday. Both incidents prompted an investigation by law enforcement.

Earlier in April, a Zoomombomber broke into a classroom at a Berkeley high school, exposing himself to students when he made obscene screams, prompting school officials to suspend all videoconferencing classes.

In late March, pornography was exposed in an online classroom at a Georgia high school, as was the classroom at a Utah elementary school in early April. On April 23, a Zoom meeting of the Oklahoma State Board of Education was interrupted when Zoomombombers was flooded with racial slurs on the video’s chat channel.

Zoom, which was popular during the outbreak, has hired dozens of outside security advisers in the past two weeks. Among them are former security and privacy experts from companies such as Facebook, Microsoft and Google who want to quickly resolve security vulnerabilities, according to people familiar with the matter.

Alex Stamos, Facebook’s former chief security officer, said Zoom’s move was a reference to Microsoft’s efforts to restore the image of Windows software nearly two decades ago. Microsoft’s reputation was damaged by years of security issues that made Windows users vulnerable to Internet worms and other viruses before it switched to “trusted computing” in 2002.

The security companies that Zoom currently brings in include NCC Group PLC, a British security provider, Trail of Bits, based in New York, USA, Bishop Fox in Tempe, Arizona, and Praetorian Security in Austin, Texas. Zoom is also using security intelligence services provided by DarkTower, the security intelligence arm of CrowdStrike and Queen Associates.

Another hacker sold a 0 day remote code that affected the Zoom Windows client on the dark web to execute the exploit code for $500,000. It also comes with a vulnerability abuse code for a Zoom macOS client.

Such exploits have no fixed price, and the foreign vulnerability trading platform Zerodium offers between $20 million and $2.5 million for such exploits, depending on the popularity of the affected software or systems, the level of security, and the quality of the exploits submitted.

At present, the vulnerability and source code has not been made public, familiar with the 0 day vulnerability market related people said that there have been vulnerability trading agents with the business to contact the purchase loophole. Adriel Desautels, founder of the vulnerability trading platform Netragard, said the sale of two 0 day vulnerabilities affected macOS one and the other affected Windows.

Lawsuits with Facebook and LinkedIn

A new lawsuit has been filed in California against Facebook and LinkedIn, accusing the companies of “wiretapping” the personal data of Zoom users.

In a statement to Bloomberg Law’s Dan Stoller, Facebook denied the allegations, saying: “Zoom’s use of the Facebook SDK did not enable Facebook to ‘eavesdrop’ on Zoom’s call content; the SDK was not designed to share it or not. There is no legal basis for this lawsuit and we will vigorously defend it. “

More than half a million Zoom accounts are sold on the Dark Web for less than a cent or even a “free gift.” According to Business Today, Cyble, a cyber security intelligence firm, found on the dark web and hacking forums that more than half a million Zoom accounts were being sold, including email addresses, passwords, personal meeting links and keys. The seller’s asking price is only 0.002 cents per share, and some are even completely free, for example, 290 accounts related to colleges such as the University of Vermont, the University of Colorado, Dartmouth, lafayette, and the University of Florida are released free of charge.

According to Cyble, the seller’s goal is not to make money, but to enhance his “reputation” in the hacking community. By collecting compromised account and password information on the Internet, hackers try to log in to Zoom in in bulk, and then generate a list of successful logins and sell them at a list price. Hackers are often able to access this information because users use the same account number and password on different platforms.
