• Apple Faces Lawsuit Over Alleged Failures to Detect CSAM — Apple is going through a proposed $1.2 billion class motion lawsuit that is accusing the corporate of allegedly failing to detect and report unlawful youngster pornography. In August 2021, Apple unveiled a brand new function within the type of a privacy-preserving iCloud picture scanning device for detecting youngster sexual abuse materials (CSAM) on the platform. Nonetheless, the venture proved to be controversial, with privateness teams and researchers elevating issues that such a device could possibly be a slippery slope and that it could possibly be abused and exploited to compromise the privateness and safety of all iCloud customers. All of this led to Apple killing the trouble formally in December 2022. “Scanning each consumer’s privately saved iCloud knowledge would create new menace vectors for knowledge thieves to search out and exploit,” it mentioned on the time. “Scanning for one kind of content material, for example, opens the door for bulk surveillance and will create a want to look different encrypted messaging programs throughout content material sorts.” In response to the lawsuit, Apple mentioned it is working to fight these crimes with out sacrificing consumer privateness and safety by means of options like Communication Security, which warns kids once they obtain or try to ship content material that comprises nudity.
• Menace Actors Exploit Apache ActiveMQ Vulnerability — The menace actors are actively exploiting a identified safety flaw in Apache ActiveMQ (CVE-2023-46604) in assaults focusing on South Korea to ship varied malware like cryptocurrency miners, an open-source RAT referred to as Quasar RAT, Quick Reverse Proxy (FRP), and an open-source ransomware referred to as Mauri. “System directors should test if their present Apache ActiveMQ service is among the vulnerable variations under and apply the newest patches to forestall assaults that exploit identified vulnerabilities,” AhnLab mentioned.
• Citrix Warns of Password Spraying Assaults on NetScaler/NetScaler Gateway — Citrix has warned that its NetScaler home equipment are the goal of password spraying assaults as a part of broader campaigns noticed throughout varied merchandise and platforms. “These assaults are characterised by a sudden and vital enhance in authentication makes an attempt and failures, which set off alerts throughout monitoring programs, together with Gateway Insights and Lively Listing logs,” the corporate mentioned, including they might end in extreme logging, administration CPU overload, and equipment instability.

• BadRAM Depends on $10 Tools to Break AMD Safety — Educational researchers from KU Leuven, the College of Lübeck, and the College of Birmingham have devised a brand new approach referred to as BadRAM (CVE-2024-21944, CVSS rating: 5.3) that employs $10 off-the-shelf gear combining Raspberry Pi Pico, a DDR Socket, and a 9V supply to breach AMD’s Safe Encrypted Virtualization (SEV) ensures. The examine discovered that “tampering with the embedded SPD chip on business DRAM modules permits attackers to bypass SEV protections — together with AMD’s newest SEV-SNP model.” In a nutshell, the assault makes the reminiscence module deliberately misreport its measurement, thus tricking the CPU into accessing non-existent addresses which might be covertly mapped to present reminiscence areas. This might end in a state of affairs the place the SPD metadata is modified to make an hooked up reminiscence module seem bigger than it’s, thereby permitting an attacker to overwrite bodily reminiscence. “BadRAM fully undermines belief in AMD’s newest Safe Encrypted Virtualization (SEV-SNP) expertise, which is extensively deployed by main cloud suppliers, together with Amazon AWS, Google Cloud, and Microsoft Azure,” safety researcher Jo Van Bulck instructed The Hacker Information. “Much like Intel SGX/TDX and Arm CCA, AMD SEV-SNP is a cornerstone of confidential cloud computing, making certain that prospects’ knowledge stays constantly encrypted in reminiscence and safe throughout CPU processing. Notably, as a part of AMD’s rising market share, the corporate lately reported its highest-ever share of server CPUs. BadRAM for the primary time research the safety dangers of dangerous RAM — rogue reminiscence modules that intentionally present false data to the processor throughout startup. ” AMD has launched firmware updates to handle the vulnerability. There is no such thing as a proof that it has been exploited within the wild.
• Meta Fixes WhatsApp View As soon as Media Privateness Problem — WhatsApp seems to have silently mounted a difficulty that could possibly be abused to trivially bypass a function referred to as View As soon as that stops message recipients from forwarding, sharing, copying, or taking a screenshot after it has been considered.
