Apple has released an emergency security update for two zero-day vulnerabilities which may have already been exploited.

Apple has released emergency security updates for iOS 17.1.2 and iPadOS 17.1.2 to patch for two zero-day vulnerabilities that may have been actively exploited.

Apple said both vulnerabilities were in the WebKit component, which is the engine that powers Safari browser on Macs as well as all browsers on iPhones and iPads. It is also the web browser engine used by Mail, App Store, and many other apps on macOS, iOS, and Linux.

The updates are available for the following:

*   iPhone XS and later
*   iPad Pro 12.9-inch 2nd generation and later
*   iPad Pro 10.5-inch
*   iPad Pro 11-inch 1st generation and later
*   iPad Air 3rd generation and later
*   iPad 6th generation and later
*   iPad mini 5th generation and later.
*   macOS Sonoma 14.1.2
*   Safari 17.1.2.

The updates may already have reached you if you automatically update, but it doesn’t hurt to check if your device is at the latest update level.

If a Safari update is available for your device, you can get it by updating your iPhone or iPad or updating your Mac.

**We don’t just report on threats—we remove them**

Cybersecurity risks should never spread beyond a headline. Keep threats off your devices by downloading Malwarebytes today.

Cybersecurity researchers have discovered a new variant of an emerging botnet called **P2PInfect** that's capable of targeting routers and IoT devices.

The latest version, per Cado Security Labs, is compiled for Microprocessor without Interlocked Pipelined Stages (MIPS) architecture, broadening its capabilities and reach.

"It's highly likely that by targeting MIPS, the P2PInfect developers intend to infect routers and IoT devices with the malware," security researcher Matt Muir said in a report shared with The Hacker News.

P2PInfect, a Rust-based malware, was first disclosed back in July 2023, targeting unpatched Redis instances by exploiting a critical Lua sandbox escape vulnerability (CVE-2022-0543, CVSS score: 10.0) for initial access.

A subsequent analysis from the cloud security firm in September revealed a surge in P2PInfect activity, coinciding with the release of iterative variants of the malware.

The new artifacts, besides attempting to conduct SSH brute-force attacks on devices embedded with 32-bit MIPS processors, packs in updated evasion and anti-analysis techniques to fly under the radar.

The brute-force attempts against SSH servers identified during the scanning phase are carried out using common username and password pairs present within the ELF binary itself.

It's suspected that both SSH and Redis servers are propagation vectors for the MIPS variant owing to the fact that it's possible to run a Redis server on MIPS using an OpenWrt package known as redis-server.

One of the notable evasion methods used is a check to determine if it's being analyzed and, if so, terminate itself, as well as an attempt to disable Linux core dumps, which are files automatically generated by the kernel after a process crashes unexpectedly.

The MIPS variant also includes an embedded 64-bit Windows DLL module for Redis that allows for the execution of shell commands on a compromised system.

"Not only is this an interesting development in that it demonstrates a widening of scope for the developers behind P2PInfect (more supported processor architectures equals more nodes in the botnet itself), but the MIPS32 sample includes some notable defense evasion techniques," Cado said.

"This, combined with the malware's utilization of Rust (aiding cross-platform development) and rapid growth of the botnet itself, reinforces previous suggestions that this campaign is being conducted by a sophisticated threat actor."

**Disclaimer**

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
