A new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride

In a paper published in Science Advances, researchers at the University of Technology Sydney (UTS) in collaboration with the University of Minnesota and Kyung Hee University have found a new way to control quantum light sources, which is one of the key elements needed before quantum technologies can be used reliably in real-world systems.

Lead author Dr. Angus Gale says the research gives scientists a new control mechanism for tiny quantum light sources, bringing them a step closer to being used in practical quantum technologies such as quantum computing, secure communication and ultrasensitive sensing.

“You can measure these quantum emitters and see that they exist, but it’s hard to make them work in practice. This gives us a lever to get closer to that—a step toward the realization of quantum technologies,” said Dr. Gale.

Unpatchable ‘usbliter8’ Exploit Breaks Apple A12 and A13 SecureROM Boot Chain

Security researchers at Paradigm Shift have published a working exploit, dubbed usbliter8, that achieves arbitrary code execution inside the SecureROM of Apple’s A12 and A13 chips.

That code is burned into the silicon at manufacture. No software update can reach it. Affected devices will carry this flaw for as long as they stay in use.

This is not a remote attack. It requires physical possession of the device, which must be in DFU mode and connected via USB to a dedicated RP2350-based microcontroller board. With that setup, the exploit finishes in under two seconds, before Apple’s signed boot chain loads.

Klue OAuth breach victim list grows as Icarus hackers claim attack

Market intelligence platform Klue has publicly confirmed a recent security incident that allowed threat actors to steal OAuth tokens used to connect to customers’ Salesforce environments, as the new “Icarus” extortion group publicly claims the attack.

The disclosure comes after cybersecurity firms Huntress and ReliaQuest detailed how attackers abused compromised Klue Battlecards integrations to steal Salesforce CRM data from multiple organizations.

In a statement published this week, Klue CEO Jason Smith confirmed that the company discovered unauthorized activity on June 12 affecting part of Klue’s integration infrastructure.

Hackers exploit info disclosure bug in Gravity SMTP WordPress plugin

Threat actors are exploiting an unauthenticated information disclosure vulnerability in the WordPress plugin Gravity SMTP, active on 100,000 sites.

The flaw is tracked as CVE-2026–4020 and received a medium severity rating. It affects all versions of the plugin from 2.1.4 and older and has been addressed in version 2.1.5, released on March 17.

WordPress security company Defiant is warning that hackers are actively exploiting the vulnerability. The company’s Wordfence firewall has blocked more than 17 million attempts against protected customers.

Targeting enzyme could block cancer spread to brain with fewer side effects

A new study has identified a more precise and effective way to prevent cancer from spreading to the brain. The paper, published in the Proceedings of the National Academy of Sciences, details the development of novel drug candidates that target a key enzyme implicated in the spread of lung, breast, skin and other cancers to the brain. The work builds on a promising new therapeutic strategy first reported by the same group of researchers last year.

The new drug candidates are designed to intercept rogue cancer cells before they depart from primary tumors and ultimately travel to the brain.

Lead author Sheila Singh, based at both King’s College London and McMaster University, says this type of cancer—called metastatic brain cancer—is the most common type of brain tumor in adults and comes with an extremely grim outlook, with 90% of patients dying within one year of diagnosis.
