The ubiquity of electronic devices makes it essential to use encryption and anti-counterfeiting tools to protect the privacy and security of users. With the growing expansion of the Internet of Things, protection against attacks that violate the authenticity of products is increasingly necessary. Traditionally, message protection has been based on different systems: passwords, digital signatures or encryption. This cryptography is based on unknown keys to a possible attacker, but unfortunately these systems are becoming obsolete as new more invasive attacks appear: malware, API attacks or physical hardware attacks.

While quantum computing slowly progresses towards the cryptographic paradigm, the so-called physically unclonable functions (PUFs) are presented as the choice to ensure unique and effective identification. A PUF is a device that has unique and non-repeatable physical properties that can be translated into usable bits of information. The idea of applying random physical characteristics to identify systems or people is not new: for example, the identification of individuals using the fingerprint dates from the 19th century. More recently, the identity of electronic devices has been established using PUFs, which are “electronic fingerprints” of an integrated circuit.

Authentication based on PUFs comprises a chip manufactured by intrinsically random processes that make cloning almost impossible, even though all the details of the manufacturing process are known. The measurements of the various physical properties of the PUF depend on the properties of the chip at the nanoscale, thus constitute a very powerful anti-fraud and anti-counterfeiting technology. To be implementable at an industrial level, this chip must be low cost, scalable and its properties must be easily measurable by means of an identifiable function.

As the amount of data stored in devices and shared over the internet continuously increases, computer scientists worldwide are trying to devise new approaches to secure communications and protect sensitive information. Some of the most well-established and valuable approaches are cryptographic techniques, which essentially encrypt (i.e., transform) data and texts exchanged between two or more parties, so that only senders and receivers can view it in its original form.

Physical unclonable functions (PUFs), devices that exploit “random imperfections” unavoidably introduced during the manufacturing of devices to give physical entities unique “fingerprints” (i.e., trust anchors). In recent years, these devices have proved to be particularly valuable for creating cryptographic keys, which are instantly erased as soon as they are used.

Researchers at Peking University and Jihua Laboratory have recently introduced a new system to generate cryptographic primitives, consisting of two identical PUFs based on aligned carbon nanotube (CNT) arrays. This system, introduced in a paper published in Nature Electronics, could help to secure communications more reliably, overcoming some of the vulnerabilities of previously proposed PUF devices.

In November last year, an undercover agent with the FBI was inside a group on Amazon-owned messaging app Wickr, with a name referencing young girls. The group was devoted to sharing child sexual abuse material (CSAM) within the protection of the encrypted app, which is also used by the U.S. government, journalists and activists for private communications. Encryption makes it almost impossible for law enforcement to intercept messages sent over Wickr, but this agent had found a way to infiltrate the chat, where they could start piecing together who was sharing the material.

As part of the investigation into the members of this Wickr group, the FBI used a previously unreported search warrant method to force one member to unlock the encrypted messaging app using his face. The FBI has previously forced users to unlock an iPhone with Face ID, but this search warrant, obtained by Forbes, represents the first known public record of a U.S. law enforcement agency getting a judge’s permission to unlock an encrypted messaging app with someone’s biometrics.

According to the warrant, the FBI first tracked down the suspect by sending a request for information, via an unnamed foreign law enforcement partner, to the cloud storage provider hosting the illegal images. That gave them the Gmail address the FBI said belonged to Christopher Terry, a 53-year-old Knoxville, Tennessee resident, who had prior convictions for possession of child exploitation material. It also provided IP addresses used to create the links to the CSAM. From there, investigators asked Google and Comcast via administrative subpoenas (data requests that don’t have the same level of legal requirements as search warrants) for more identifying information that helped them track down Terry and raid his home.

Check Point Research, the Threat Intelligence division of the company, a leading global cybersecurity specialist provider, has released its Global Threat Index for the month of June 2022. Researchers have found that Emotet continues to be the number one malware and has also increased its global incidence by around 6%. Continuing with its climb of the last month, Snake Keylogger sneaks into the top three positions, taking the Formbook position, both still far from Emotet.

Emotet, has affected 14% of organizations around the world in June, an increase that is almost double compared to the previous month. This malware is highly profitable thanks to its ability to go unnoticed. Its persistence also makes it difficult to remove once a device is infected, making it the perfect tool in a cybercriminal’s arsenal. Conceived as a banking Trojan, it is often distributed via phishing emails and has the ability to embed other malware, increasing its ability to cause widespread damage.

The US Department of Commerce’s National Institute of Standards and Technology (NIST) has selected the first-ever group of encryption tools that could potentially withstand the attack of a quantum computer.

The four selected encryption algorithms will now reportedly become part of NIST’s post-quantum cryptographic (PQC) standard, which should be finalized in about two years.

More specifically, for general encryption (used for access to secure websites), NIST has selected the CRYSTALS-Kyber algorithm.

Telegram, a leading encrypted messaging and social media application, has been compromised by Russia, according to a NATO-backed assessment.

“Telegram is not really as it used to be,” Janis Sarts, the director of NATO’s Strategic Communications Center of Excellence in Riga, Latvia, told the Washington Examiner. “I do have reasons to believe that there is not full integrity. … Certainly, I would not see it as a secure platform.”

The messaging service, founded in Dubai by a Russian tech titan who has clashed with Russian President Vladimir Putin’s surveillance apparatus, rocketed to global popularity in 2014 as one of the first applications to offer users the ability to communicate on an encrypted line. It proved valuable to Belarusian protesters who denounced President Alexander Lukashenko’s self-declared victory in a 2020 presidential election, but a warning about the program has begun to circulate among Western officials.

A new hack called Hertzbleed can read snippets of data from computer chips remotely and could leave cryptography algorithms vulnerable to attack.

The Quantum ransomware, a strain first discovered in August 2021, were seen carrying out speedy attacks that escalate quickly, leaving defenders little time to react.

The threat actors are using the IcedID malware as one of their initial access vectors, which deploys Cobalt Strike for remote access and leads to data theft and encryption using Quantum Locker.

The technical details of a Quantum ransomware attack were analyzed by security researchers at The DFIR Report, who says the attack lasted only 3 hours and 44 minutes from initial infection to the completion of encrypting devices.

The 3D-printed containers keep a log of all break-in attempts, meaning your snail mail just got way safer.

Suppose you want to mail a court document to someone across the country—you don’t want anyone to see the secure information inside, of course. So, you seal it into a container that has special sensors built into its walls, and electronics that monitor the shield of sensors. Now, the container is armed and monitoring.
