Exclusive: Chat is Google’s next big fix for Android’s messaging mess - The Verge
But remember, Chat is a carrier-based service, not a Google service. It’s just “Chat,” not “Google Chat.” In a sign of its strategic importance to Google, the company has spearheaded development on the new standard, so that every carrier’s Chat services will be interoperable. But, like SMS, Chat won’t be end-to-end encrypted, and it will follow the same legal intercept standards. In other words: it won’t be as secure as iMessage or Signal.

Encryption 101: a malware analyst's primer - Malwarebytes Labs | Malwarebytes Labs
While most in the security industry know what encryption is, many lack a basic understanding of how it is used in malware—especially ransomware. Because of this, we thought it would be beneficial to do an introductory primer on encryption mechanisms and how they are exploited for malicious purposes.
We will start with a introduction to encryption in general, and follow up with the main methods used to encrypt files used by ransomware. In part two of this blog series, we’ll use a recent ransomware variant detected by Malwarebytes as Ransom.ShiOne to highlight the key weaknesses in encryption to look out for when trying to decrypt files.
What is encryption?
In the simplest of terms, encryption is the process of encoding information so that only authorized parties can access it, and those who are not authorized cannot. In computing, encryption is the method by which data is converted from a readable format (plaintext) to an encoded one (ciphertext) that can only be decoded by another entity if they have access to a decryption key. While encryption was long used by the military to facilitate secret communication, today it is used to secure data in transit and in storage, as well as to authenticate and verify identities.
Unfortunately, encryption is also used for malicious purposes, as is the case with ransomware.

Apple’s New iMac Pro Delivers Enhanced Security with the T2 Chip | The Mac Security Blog
Have you seen the new iMac Pro? What a beast! With a gorgeous 5K display, up to 18 cores of CPU goodness and slick AMD Radeon Vega graphics options, the iMac Pro is a serious contender in the pro market. For those interested in Mac security, what's particularly noteworthy in Apple's new iMac Pro is a dedicated chip called the T2.
In Apple's own words, the T2 does the following:
Introducing the Apple T2 chip, our second-generation custom Mac silicon. By redesigning and integrating several controllers found in other Mac systems — like the system management controller, image signal processor, audio controller, and SSD controller — T2 delivers new capabilities to the Mac. For instance, the T2 image signal processor works with the FaceTime HD camera to enable enhanced tone mapping, improved exposure control, and face detection–based auto exposure and auto white balance. T2 also makes iMac Pro even more secure, thanks to a Secure Enclave coprocessor that provides the foundation for new encrypted storage and secure boot capabilities. The data on your SSD is encrypted using dedicated AES hardware with no effect on the SSD’s performance, while keeping the Intel Xeon processor free for your compute tasks. And secure boot ensures that the lowest levels of software aren’t tampered with and that only operating system software trusted by Apple loads at startup.

GrayKey iPhone unlocker poses serious security concerns - Malwarebytes Labs | Malwarebytes Labs
Ever since the case of the San Bernadino shooter pitted Apple against the FBI over the unlocking of an iPhone, opinions have been split on providing backdoor access to the iPhone for law enforcement. Some felt that Apple was aiding and abetting a felony by refusing to create a special version of iOS with a backdoor for accessing the phone’s data. Others believed that it’s impossible to give backdoor access to law enforcement without threatening the security of law-abiding citizens.
In an interesting twist, the battle ended with the FBI dropping the case after finding a third party who could help. At the time, it was theorized that the third party was Cellebrite. Since then it has become known that Cellebrite— an Israeli company—does provide iPhone unlocking services to law enforcement agencies.

Daring Fireball: GrayKey iPhone Unlocker Poses Serious Security Concerns
Thomas Reed, writing for the Malwarebytes Labs blog...
So the phone is only connected to the box for two minutes, and then the phone itself displays the passcode after it’s cracked? If I’m reading this right, the box must jailbreak the iPhone and install the cracking software on the iPhone itself. I guess that would explain how they get around iOS’s (optional) wipe-after-10-wrong-guesses feature, as well as the escalating delays after a few wrong guesses.
Hopefully Apple can figure out how to fix this jailbreak. If you’re concerned about this, you ought to switch to a stronger alphanumeric passphrase.
