In the first, hackers encrypt data with ransomware A and then re-encrypt that data with ransomware B. The other path involves what Emsisoft calls a “side-by-side encryption” attack, in which attacks encrypt some of an organization’s systems with ransomware A and others with ransomware B.
New paper: “ Encrypted Cloud Photo Storage Using Google Photos “: Abstract: Cloud photo services are widely used for persistent, convenient, and often free photo storage, which is especially useful for mobile devices.
The Bill provides no explicit protection for encryption, and if implemented as written, could empower OFCOM to try to force the proactive scanning of private messages on end-to-end encrypted communication services – nullifying the purpose of end-to-end encryption as a result and compromising the privacy of all users.
Researchers have found a major encryption flaw in 100 million Samsung Galaxy phones. Here are the details: As we discussed in Section 3, the wrapping key used to encrypt the key blobs (HDK) is derived using a salt value computed by the Keymaster TA. GSM needs a new nonce for every encryption.

After way too many years, Apple is finally encrypting iCloud backups : Based on a screenshot from Apple, these categories are covered when you flip on Advanced Data Protection: device backups, messages backups, iCloud Drive, Notes, Photos, Reminders, Safari bookmarks, Siri Shortcuts, Voice Memos, and Wallet Passes.
In 2018, Australia passed the Assistance and Access Act, which—among other things—gave the government the power to force companies to break their own encryption. Examples include certain source code, encryption, cryptography, and electronic hardware. We in the encryption space call that last one “ nerd harder.”
Apple announced PQ3 , its post-quantum encryption standard based on the Kyber secure key-encapsulation protocol, one of the post-quantum algorithms selected by NIST in 2022. There’s a lot of detail in the Apple blog post , and more in Douglas Stabila’s security analysis. I am of two minds about this.
EDITED TO ADD: Good article : One – ML-KEM [PDF] (based on CRYSTALS-Kyber) – is intended for general encryption, which protects data as it moves across public networks. My recent writings on post-quantum cryptographic standards. NIST plans to select one or two of these algorithms by the end of 2024.
“Turns out the [AES] encryption key in that script is the first AES 128-bit CBC example key listed in the NIST document SP800-38A [PDF]” […]. The search results pointed to a common public key that shows up in online tutorials like “ RSA Encryption & Decryption Example with OpenSSL in C.
The facts aren’t news, but Zoom will pay $85M — to the class-action attorneys, and to users — for lying to users about end-to-end encryption, and for giving user data to Facebook and Google without consent.
At some point in the not-so-distant future, quantum computers are going to pose a major threat to today’s encryption mechanisms and encrypted data. To begin with, all of today’s encrypted communications could potentially be at risk of being leaked and abused.
Researchers have calculated the quantum computer size necessary to break 256-bit elliptic curve public-key cryptography: Finally, we calculate the number of physical qubits required to break the 256-bit elliptic curve encryption of keys in the Bitcoin network within the small available time frame in which it would actually pose a threat to do so.
“If we can recover the RSA-512 Public Key from the registry, we can crack it and get the 256-bit AES Key that encrypts the files! . “If we can recover the RSA-512 Public Key from the registry, we can crack it and get the 256-bit AES Key that encrypts the files!” ” they wrote. Technical details.
The cryptocurrency fintech startup Prime Trust lost the encryption key to its hardware wallet—and the recovery key—and therefore $38.9 It is now in bankruptcy. I can’t understand why anyone thinks these technologies are a good idea.
Facebook has responded by encrypting the entire URL into a single ciphertext blob. Firefox users may enable URL stripping in all Firefox modes , but this requires manual configuration. Brave Browser strips known tracking parameters from web addresses as well.
Rolling Stone is reporting that the UK government has hired the M&C Saatchi advertising agency to launch an anti-encryption advertising campaign. Presumably they’ll lean heavily on the “think of the children!” ” rhetoric we’re seeing in this current wave of the crypto wars.
As I discussed last month, unless we take actions soon, a tremendous amount of data that is today protected through the use of encryption will become vulnerable to exposure. To protect data in the quantum computing era , therefore, we must change how we encrypt.
It is no secret that cybersecurity professionals universally recommend that people, businesses, and governments employ strong encryption as one of several methods of protecting sensitive information.
The headline is pretty scary: “ China’s Quantum Computer Scientists Crack Military-Grade Encryption.” ” No, it’s not true. This debunking saved me the trouble of writing one. It all seems to have come from this news article , which wasn’t bad but was taken widely out of proportion.
Starting next year : Our longstanding offering won’t fundamentally change next year, but we are going to introduce a new offering that’s a big shift from anything we’ve done before—short-lived certificates. Specifically, certificates with a lifetime of six days.
It’s happened. Details here , and tech details here (for messages in transit) and here (for messages in storage) Rollout to everyone will take months, but it’s a good day for both privacy and security. Slashdot thread.
Enter attribute-based encryption ( ABE ) an advanced type of cryptography that’s now ready for prime time. ABE makes it much more difficult to fraudulently decrypt an asset in its entirety; it does this by pulling user and data attributes into the encryption picture — in a way that allows decryption to be flexible.
According to NBC news , two officials — a senior FBI official who asked not to be named and Jeff Greene, executive assistant director for cybersecurity at CISA– both recommended using encrypted messaging apps to Americans who want to minimize the chances of China’s intercepting their communications.
The UK government has demanded to be able to access encrypted data stored by Apple users worldwide in its cloud service. The main goal for the Home Office is an optional feature that turns on end-to-end encryption for backups and other data stored in iCloud. Since then, privacy focused groups have uttered their objections.
In what is surely an unthinking cut-and-paste issue, page 921 of the Brexit deal mandates the use of SHA-1 and 1024-bit RSA: The open standard s/MIME as extension to de facto e-mail standard SMTP will be deployed to encrypt messages containing DNA profile information. x and inter-operates among all major e-mail software packages.
A new audit of DeepSeek's mobile app for the Apple iOS operating system has found glaring security issues, the foremost being that it sends sensitive data over the internet sans any encryption, exposing it to interception and manipulation attacks.
Ransomware encrypts data and demands a ransom in exchange for decryption. As data recovery is impossible if the encryption key is not obtained, some companies suffer from considerable damage, such as the payment of huge amounts of money or the loss of important data.
[no description provided] Adrian Colyer has an interesting summary of a recent paper, " Why your encrypted database is not secure " in his excellent "morning paper" blog. Many recent encrypted databases make strong claims of provable security against snapshot attacks. an attacker that does a one-off exfiltration).
European law enforcement agencies have taken down yet another encrypted messaging service mainly used by criminals. The Matrix encrypted messaging service was an invite-only service which was also marketed under the names Mactrix, Totalsec, X-quantum, or Q-safe. de Vries in 2021.
