• Apple Faces Lawsuit Over Alleged Failures to Detect CSAM — Apple is dealing with 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 instrument for detecting youngster sexual abuse materials (CSAM) on the platform. Nonetheless, the venture proved to be controversial, with privateness teams and researchers elevating considerations that such a instrument may very well be a slippery slope and that it may very well be abused and exploited to compromise the privateness and safety of all iCloud customers. All of this led to Apple killing the hassle formally in December 2022. “Scanning each person’s privately saved iCloud information would create new risk vectors for information thieves to search out and exploit,” it stated on the time. “Scanning for one sort of content material, as an example, opens the door for bulk surveillance and will create a need to go looking different encrypted messaging methods throughout content material sorts.” In response to the lawsuit, Apple stated it is working to fight these crimes with out sacrificing person privateness and safety by means of options like Communication Security, which warns youngsters once they obtain or try to ship content material that comprises nudity.
• Risk Actors Exploit Apache ActiveMQ Vulnerability — The risk actors are actively exploiting a identified safety flaw in Apache ActiveMQ (CVE-2023-46604) in assaults concentrating 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 examine if their present Apache ActiveMQ service is without doubt one of the inclined variations under and apply the newest patches to stop assaults that exploit identified vulnerabilities,” AhnLab stated.
• 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 improve in authentication makes an attempt and failures, which set off alerts throughout monitoring methods, together with Gateway Insights and Energetic Listing logs,” the corporate stated, including they may lead to extreme logging, administration CPU overload, and equipment instability. Organizations are beneficial to allow multi-factor authentication for Gateway and create responder insurance policies to dam sure endpoints, and make the most of an online utility firewall (WAF) to dam suspicious IP addresses.
• 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 tools combining Raspberry Pi Pico, a DDR Socket, and a 9V supply to breach AMD’s Safe Encrypted Virtualization (SEV) ensures. The research 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 are covertly mapped to current reminiscence areas. This might lead to a state of affairs the place the SPD metadata is modified to make an connected reminiscence module seem bigger than it’s, thereby permitting an attacker to overwrite bodily reminiscence. “BadRAM utterly 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 informed The Hacker Information. “Much like Intel SGX/TDX and Arm CCA, AMD SEV-SNP is a cornerstone of confidential cloud computing, guaranteeing that prospects’ information stays repeatedly 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 unhealthy RAM — rogue reminiscence modules that intentionally present false info to the processor throughout startup. ” AMD has launched firmware updates to handle the vulnerability. There isn’t a proof that it has been exploited within the wild.
• Meta Fixes WhatsApp View As soon as Media Privateness Challenge — WhatsApp seems to have silently mounted a difficulty that may very well be abused to trivially bypass a function referred to as View As soon as that forestalls message recipients from forwarding, sharing, copying, or taking a screenshot after it has been seen.
