Latest cybersecurity reporting from selected sources.

The security vulnerability known as React2Shell is being exploited by threat actors to deliver malware families like KSwapDoor and ZnDoor, according to findings from Palo Alto Networks Unit 42 and NTT Security

Cybersecurity researchers have disclosed details of two new Android malware families dubbed FvncBot and SeedSnatcher, as another upgraded version of ClayRat has been spotted in the wild

Researchers built an inexpensive device that circumvents chipmakers' confidential computing protections and reveals weaknesses in scalable memory encryption.

A group of academic researchers from Georgia Tech, Purdue University, and Synkhronix have developed a side-channel attack called TEE.Fail that allows for the extraction of secrets from the trusted execution environment (TEE) in a computer's main processor, including Intel's Software Guard eXtensions (SGX) and Trust Domain Extensions (TDX) and AMD's Secure Encrypted Virtualization with Secure

Academic researchers developed a side-channel attack called TEE.Fail, which allows extracting secrets from the trusted execution environment in the CPU, the highly secure area of a system, such as Intel's SGX and TDX, and AMD's SEV-SNP. [...]

Russian Intel Hackers Flexible in Face of DetectionRussia-linked threat group COLDRIVER rapidly replaced its exposed malware with a stealthier PowerShell variant, using fake CAPTCHA prompts and cryptographic key-splitting to evade detection and escalate surveillance on NGOs, dissidents and policy experts, according to new research.

In yet another piece of research, academics from Georgia Institute of Technology and Purdue University have demonstrated that the security guarantees offered by Intel's Software Guard eXtensions (SGX) can be bypassed on DDR4 systems to passively decrypt sensitive data

Researchers have demonstrated an attack that can break through modern Intel and AMD processor technologies that protect encrypted data stored in memory.

A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors

Cybersecurity researchers have discovered two new malware families, including a modular Apple macOS backdoor called CHILLYHELL and a Go-based remote access trojan (RAT) named ZynorRAT that can target both Windows and Linux systems

Researchers at ETH Zürich have discovered yet another security flaw that they say impacts all modern Intel CPUs and causes them to leak sensitive data from memory, showing that the vulnerability known as Spectre continues to haunt computer systems after more than seven years

ETH Zurich boffins exploit branch prediction race condition to steal info from memory, fixes have mild perf hit Researchers at ETH Zurich in Switzerland have found a way around Intel's defenses against Spectre, a family of data-leaking flaws in the x86 giant's processor designs that simply won't die.…

Security bods can earn up to $10K per report Ransomware threat hunters can now collect rewards of $10,000 for each piece of intel they file under a new bug bounty that aims to squash extortionists.…

Researchers say there's dissent in the ranks. Plus: An AI tool lets you have a go yourself at analysing the data Hundreds of thousands of internal messages from the Black Basta ransomware gang were leaked by a Telegram user, prompting security researchers to bust out their best Russian translations post haste.…

Google Expects Tactics to Spread; Global Targets and Other Services at RiskRussian nation-state hackers are using phishing attacks to target Ukrainian users of the chat app Signal, say security researchers. Rather than circumventing Signal's end-to-end encryption via a cryptographic attack, attackers use malicious prompting to prod victims into exposing messages.

Addressing cyber threats before they have a chance to strike or inflict serious damage is by far the best security approach any company can embrace. Achieving this takes a lot of research and proactive threat hunting. The problem here is that it is easy to get stuck in endless arrays of data and end up with no relevant intel.  To avoid this, use these five battle-tested techniques that are

More than six years after the Spectre security flaw impacting modern CPU processors came to light, new research has found that the latest AMD and Intel processors are still susceptible to speculative execution attacks

Cybersecurity researchers have discovered a new Android banking trojan called BlankBot targeting Turkish users with an aim to steal financial information

Intel works closely with academic researchers on hardware flaws and coordinates efforts with other vendors to roll out fixes for emerging vulnerabilities. That wasn't always the case.

"Indirector" targets a speculative execution component in silicon that previous research has largely overlooked.
