While several Israel-based security firms suggested the attack was carried out by Iranian hackers, government officials told the Jerusalem Post that it is still uncertain who was behind the intrusion.

Everyone seems to have rushed to attribute the incident to Iranian hackers in light of similar intrusions Iranian-linked groups orchestrated in the spring and summer of 2020 against Israeli water and wastewater management systems.

This is not the first time that hackers breach an air raid and public address system to sound false alarms. In previous years, hackers have also set off tornado sirens in Dallas (2017), DeSoto and Lancaster (2019), and Bastille also published research named SirenJack on how emergency alert systems manufactured by ATI Systems could be abused to set off false alarms.

New Windows 11 privacy feature: New versions of Windows 11 now come with a new privacy feature that will let users review which locally installed applications have recently accessed and used the camera and microphone. The feature is great for detecting if systems are infected with spyware that constantly accesses these devices without the user's specific approval. The feature is active in Windows 11 Preview and Dev builds.

Smart App Control: Another new feature coming to Windows 11 Insiders builds later this year is Smart App Control. This new feature works by trying to "predict" if a new app being installed on a Windows 11 system may be malicious or not. If the Windows 11 security service is unable to make a confident prediction, then Smart App Control checks to see if the app has a valid signature and allows the installation based on that check.

Smoother Exchange logins for Apple users: Microsoft said it worked together with Apple to improve the login experience for iOS and iPad users, who will soon be able to log into Exchange email servers using an OAuth token provided by their device instead of constantly having to re-type their usernames and passwords. Microsoft said it plans to notify all organizations which have iOS/iPad users still using its classic authentication scheme and prompt them to update server settings in the coming days.

Your correspondent participated in the Lowy Institute's Frontier Rules conference in Canberra this week, which is why this newsletter is a day late.

One interesting discussion at the conference concerned the Russian attack on Viasat's KA-SAT network. This newsletter previously wrote:

The researchers also looked at some of the reasons why, in 2022, so many popular websites still haven't learned anything from the hacks from the last decade.

One of the reasons they put forward was that companies are shifting their attention to multi-factor authentication, and many websites may not care to strengthen their password policies. Another was related to auditors.

"Websites need to pass security audits, and the firms who do these audits, such as Deloitte, recommend or mandate outdated practices," researchers said.

Whatever is going on at the Microsoft Security Response Center, it appears that's rubbing a lot of today's top researchers the wrong way, but also creating a lot of frustration for those who have to deal with the company’s technology on a daily basis, especially from a security posture.

Belarus leak: Belarusian hacktivist group Cyber Partisans released on Tuesday 1.5 TB of data they claim is phone calls secretly collected by the Belarusian Ministry of Internal Affairs from foreign embassies and consulates inside Belarus.

Optimism hack: In one of the most facepalm-worthy crypto-hacks of all time, the Optimism cryptocurrency project said it lost $19 million worth of funds after one of its partners sent funds to an Ethereum wallet they didn't yet have full control of. The cringeworthy IR report is here, and, according to Motherboard, the Optimism project is now pleading with the person who spotted and hijacked the errant transfer to return some of the stolen funds.

Mobike leak: Bike-sharing service Mobike leaked the passports, driver's licenses, and identity documents of more than 120,000 customers. Almost all of the identity documents were for users in Latin America, including Argentina and Brazil, TechCrunch reported, which worked for months with the vendor to have the leaky server secured.

"Our DCU investigation found Bohrium targeted customers in the US, Middle East, and India. Targets come from sectors including tech, transportation, government, and education," Hogan-Burney said.

The Microsoft exec said the group's members used fake social media profiles, often posing as recruiters, and lured employees at targeted organisations on one of the 41 malicious sites. Here, they tried to collect their personal information, which they later used in subsequent email attacks that sought to infect the victims with malware.

To date, Microsoft's DCU team has used the US court system to seize domains and server infrastructure from more than two-dozen cybercrime and espionage groups alike.
