IBM Releases Homomorphic Encryption Toolkit for iOS, macOS

Andrew Orr ·

IBM has released a toolkit for iOS and macOS to help developers to easily add homomorphic encryption into their programs.

While the technology holds great potential, it does require a significant shift in the security paradigm. Typically, inside the business logic of an application, data remains decrypted, Bergamaschi explained. But with the implementation of FHE, that’s no longer the case — meaning some functions and operations will change.

In other words, “There will be a need to rewrite parts of the business logic,” Bergamaschi said. “But the security that you gain with that, where the data is encrypted all the time, is very high.”

If you haven’t added homomorphic encryption to your technology watch list, be sure to do so. As I wrote in the past, this type of encryption lets a company perform computations on data while still keeping that data encrypted.

Security Researcher Believes Mac Backdoor ‘Tiny Shell” Still Being Used

Andrew Orr ·

Mac security researcher Jaron Bradley says he believes hackers are still using an open source macOS backdoor called “Tiny SHell.”

Tinyshell is an open source tool that operates like a shady version of SSH. It’s been a while since I’ve encountered a new sample, but I fully believe attackers are still out there using it. If you watched the Macdoored talk then you’ve seen what attackers are doing “post mortem” with this tool. However, no technical details have been discussed about the malware itself.

Amtrak Data Breach Affects Guest Rewards Accounts

Andrew Orr ·

Discovered on April 16, 2020, Amtrak suffered a data breach that affects its Amtrak Guest Rewards accounts.

The attack vector involved was compromised usernames and passwords, which may suggest the use of credentials previously leaked or stolen, or the use of brute-force methods.

Amtrak says that some personal information was viewable, although the company has not specifically said what data may have been compromised. However, Amtrak was keen to emphasize that Social Security numbers, credit card information, and other financial data was not involved in the data leak.

Roberto Escobar Sues Apple for $2.6B Over iPhone Security

Andrew Orr ·

Roberto Escobar, brother of Pablo Escobar, is suing Apple for US$2.6 billion. He claims someone hacked his iPhone and found his email through FaceTime. As a way to fight the company he’s also launching a limited edition iPhone 11 Pro 256GB, gold plated, for US$499.

According to the lawsuit, obtained by TMZ, Pablo’s brother bought an iPhone X back in April 2018, and he claims the security promise fell horribly flat. One year after buying the X, Roberto claims he got a life-threatening letter from someone named Diego, who said he found Roberto’s address through FaceTime.

In the suit, Roberto says he conducted his own investigation after receiving the letter, and found his iPhone had been compromised due to a FaceTime vulnerability.

Go to Settings > FaceTime. You can choose which address and phone number you let people contact you with, if you have multiple numbers and emails associated with your Apple ID. This won’t stop people from obtaining your address elsewhere.

Zerodium Pauses Purchases of iOS Exploits

Andrew Orr ·

Zerodium is temporarily suspending its purchasing of iOS exploits due to a high number of submissions, with the CEO saying ”iOS security is f**ked.”

Zerodium is an exploit acquisition platform that pays researchers for zero-day security vulnerabilities and then sells them to institutional customers like government organizations and law enforcement agencies. The company focuses on high-risk vulnerabilities, normally offering between $100,000 and $2 million per fully functional iOS exploit.

Lazarus Group’s Dacls RAT Affects Macs for the First Time

Andrew Orr ·

Security researcher Patrick Wardle writes that the Lazarus group’s RAT malware has been targeting macOS for the first time. MalwareBytes also published a report (and the source of my quote below). It was found to be distributed with a two-factor authentication app called MinaOTP, commonly used by Chinese users.

We believe this Mac variant of the Dcals RAT is associated with the Lazarus group, also known as Hidden Cobra and APT 38, an infamous North Korean threat actor performing cyber espionage and cyber-crime operations since 2009.

The group is known to be one of the most sophisticated actors, capable of making custom malware to target different platforms. The discovery of this Mac RAT shows that this APT group is constantly developing its malware toolset.

The conclusion I’m drawing is that it’s unlikely to affect most Mac users.

Hacker Bribed Roblox Insider to Access Kids’ Data

Andrew Orr ·

Motherboard reports that a hacker had bribed a Roblox insider to access the data of over 100 million users.

“I did this only to prove a point to them,” the hacker told Motherboard in an online chat. Motherboard granted the hacker anonymity to speak more candidly about a criminal incident.

Beyond just viewing user data, the hacker was able to reset passwords and change user data too […] The hacker said they changed the password for two accounts and sold their items. One of the screenshots appears to show the successful change of two-factor authentication settings […]

Proving a point my a**. This person tried to claim a bug bounty from Roblox. They denied it because he/she acted “more maliciously than a legitimate security researcher.” He messed with the accounts after denial, so his point was revenge.

Update: A Roblox spokesperson informed me that only a small amount of customers were affected, not 100 million, and immediate action was taken to address the issue. Additionally, it was a Roblox insider and not an employee.

Netatmo Smart Indoor Security Camera Patched After Security Issue Found

Andrew Orr ·

Following an investigation by PCMag and Bitdefender, a patch has been issued for the Netatmo Smart Indoor Security Camera.

The Bitdefender IoT Vulnerability Research Team discovered that the device is susceptible to an authenticated file write that leads to command execution (CVE-2019-17101), as well as to a privilege escalation via dirtyc0w—a local privilege escalation bug that exploits a race condition in the implementation of the copy-on-write mechanism in the kernel’s memory-management subsystem.

Many smart home devices are notoriously insecure, and this is the main reason why I don’t have any of them (Besides my robot vacuum, but I explained my reasoning).
