‎Show Risky Business News, Ep Risky Biz News: Edge adds new sandbox escape protection - 17 Mar 2024

Microsoft has developed a new security protection for its Edge web browser.

The new feature—which has no official name—aims to stop sandbox escape attacks.

The Microsoft Edge security team explains how the new protection works at a higher technical level in a blog post here.

In a super simplified explanation—the new protection works by crashing the JavaScript rendering process when an attacker tries to escape the sandbox (where a website's code is executed) and then pivot to a more high-privileged internal browser component.

It basically crashes the Renderer Process when attackers try to mess with MojoJS settings—MojoJS being the component that allows Chromium processes to talk and interact with each other.

The new feature is scheduled to roll out to all Edge users with the release of version 123 later this week.

The new protection has also been added to the Chromium open-source browser, although it's unclear when it will reach Chrome, Opera, Vivaldi, and the other Chromium-based browsers.

This marks the Edge team's second major contribution to the Chromium codebase (they had plenty, but we're only talking about the big ones). Google recently added a JITless mode to Chrome after Edge first pioneered and tested the tech back in 2021.

Breaches, hacks, and security incidents

France Travail cyberattack: Hackers have breached France's unemployment agency and stolen the personal data of nearly 43 million people. The breach affected anyone who used the agency to find a job or seek financial aid. The breach took place in February this year. The agency says hackers didn't access any financial information.

IMF breach: The International Monetary Fund (IMF) has disclosed a security breach that impacted 11 email accounts. The IMF says it discovered the hack on February 16 and has since resecured the compromised users. The organization says the investigation is still ongoing and did not formally attribute the intrusion.

Mozaic crypto-heist: The Mozaic cryptocurrency platform says that a former developer stole $2 million worth of assets from its accounts. Mozaic claims the former developer compromised a core team member and stole the private keys of a security module. They used the keys to steal funds from a fail-safe vault mechanism before it was set to be phased out. Mozaic revoked access to its systems for all employees as it investigates the hack. The company says 90% of the stolen funds have been frozen at third-party platforms and are likely to be returned.

General tech and privacy

McDonald's IT outage: McDonald's restaurants and some online services were down on Friday in what the company described as an IT outage at a third-party provider. Similar IT outages also hit Tesco and Sainsbury on the same day. Sainsbury blamed it on a software update.

Microsoft shenanigans: Microsoft is injecting popups into the Chrome browser in an attempt to get users to switch to Edge and Bing. The popups are appearing on Windows 10 and 11. This is the second time they have shown up after Microsoft pulled off the same stunt last year and called it "unintended behaviour." [Additional coverage in 9to5Google]

Cloudflare stats: Cloudflare has lost 22% of domains hosted on its infrastructure after Freenom stopped managing the .tk domain space. More than 12.6 million .tk domains have now been nulled and stopped revolving, according to Netcraft. Other domains that disappeared with the Freenom shutdown include .cf and .gq.

Twitter loses brand safety seal: After an influx of malicious ads redirecting users to crypto-scams for months and months, Twitter has lost its Brand Safety certification from the TAG ad-tech industry group.

Gab goes after fReE sPeEcH: Gab, a far-right social media platform that billed itself as the platform of free speech, has announced plans to start moderating its content.

"After facing a barrage of threats, doxxing, and other unhinged behavior over the past few weeks I've come to the conclusion that these subversive mentally ill people don’t deserve the freedom of speech, they deserve to be committed. [...] Threats and harassment are not protected by the First Amendment and they aren’t protected by Gab's terms of service. In the past we have been far too forgiving and lenient with giving people second, third, and fourth chances to change their behavior. That ends now."

Government, politics, and policy

Russia's presidential election: Rostelecom CEO Mikhail Oseevsky claimed that Ukraine's military intelligence service GUR tried to destroy Russia's electronic voting system. GUR called the statement propaganda and proceeded to mock him on their Telegram channel.

Rostelekom blocks SIP: Rostelekom is blocking the SIP protocol on its Russian network. In a letter to affected customers, the company claimed it acted on orders from the Russian Federal Security Service. The block has affected telephony services at smaller companies all over Russia.

US cybersecurity budget: The Biden administration has requested $13 billion to fund cybersecurity programs across multiple US federal agencies. CISA is set to receive $3 billion under a budget proposal for the 2025 fiscal year. The budget proposal includes $394 million for CISA's Joint Collaborative Environment (JCE), a program that allows private sector entities to work on joint CISA projects. It also allocates $116 million for new CISA staff and technology to support the agency's new cyber incident reporting program (CIRCIA). The White House’s budget proposal is unlikely to pass Congress but experts say it proves the administration’s dedication to improving cybersecurity across the US.

US Cyber Trust Mark: The FCC has formally adopted a voluntary cybersecurity labeling scheme for internet-connected devices. Named the US Cyber Trust Mark, the program was announced by the White House in July of last year. It allows vendors to apply a special shield logo on their devices if they meet basic cybersecurity requirements. Criteria include having unique and strong default passwords, receiving security updates, and restricting access to their management interfaces.

E-Root admin sentenced: US authorities have sentenced the administrator of the E-Root cybercrime marketplace to 42 months in prison. Moldovan national Sandu Boris Diaconu was arrested while trying to leave the UK in May 2021 and was extradited to the US last October.
