Threat actors enlist compromised WordPress websites in campaign targeting macOS users.
Threat actors known as WildPressure have added a macOS malware variant to their latest campaign targeting energy sector businesses, while enlisting compromised WordPress websites to carry out attacks.
Novel malware, initially identified in March 2020 and dubbed Milum, has now been retooled with a PyInstaller bundle containing a trojan dropper compatible with Windows and macOS systems, according to researchers. Compromised endpoints allow the advanced persistent threat (APT) group to download and upload files and executing commands.
On Wednesday, Kaspersky published its latest findings tied to the APT and malware, which it first discovered and reported on in March 2020. At that time, researchers noted WildPressure targeted Middle East organizations with a C++ version of a trojan it called Milum.

Apples Mac-Rechner galten lange als sichere Bastion gegen Computer-Schädlinge. Nun musste selbst der Software-Chefs des Unternehmens zugeben, dass sich das in den letzten Jahren geändert hat. Im Vergleich zu Windows steht man aber trotzdem noch gut da. Viren, gestohlene Zugangsdaten, Erpressungs-Trojaner: Wohl jeder Nutzer eines Windows-Rechners war irgendwann mal Opfer eines Computer-Schädlings. Die Macintosh-Rechner aus dem Hause Apple galten dagegen lange geradezu als Musterbeispiel für einen sicheren Rechner. Doch dieses Image hat sich in den letzten Jahren gewandelt. Und nun musste selbst der Chef der Software-Abteilung zugeben: Es gibt ein Problem.
"Wir haben heute ein Ausmaß an Malware auf dem Mac, das für uns inakzeptabel ist", erklärte Craig Federighi am Mittwoch im Rahmen des Gerichtsprozesses zwischen dem Konzern und dem "Fortnite"-Entwickler Epic Games. Jede Woche finde der Konzern nach seinen Angaben neue Schädlinge, alleine oder in Zusammenarbeit mit Drittentwicklern. In absoluten Zahlen klingt die Menge der Malware-Funden aber weniger dramatisch: 130 neue schädliche Programme für Mac-Rechner habe man seit dem letzten Mai insgesamt identifizieren könne, so Federighi. Die meisten würde Apple selbst im Hintergrund von den Rechnern entfernen. Ein Schädling habe aber alleine 300.000 Rechner befallen.

Apple hat zum zweiten Mal in diesem Monat eine Sicherheitslücke mit einem Betriebssystem-Patch geschlossen. Welche Geräte betroffen sind und was Apple an regulären Updates in den nächsten Wochen plant. Apple hat eine gefährliche Sicherheitslücke geschlossen, die Angreifer unter den Betriebssystemen iOS und iPadOS in die Lage versetzen konnte, gefährliche Malware auf den mobilen Geräten auszuführen. Wie das Unternehmen mitteilt, sollten Nutzer auf den aktuellen Mobilgeräten dazu umgehend Version 14.4.2 installieren. Nutzer älterer Geräte finden mit iOS 12.5.2 die passenden Patches. Anwender, die iOS 13 verwenden, erhalten dagegen keinen gesonderten Patch mehr und sollten upgraden. Nutzer der Apple Watch schließlich benötigen die Betriebssystemversion 7.3.3.

Après avoir déjà corrigé trois vulnérabilités zero-day exploitées par des individus malveillants en novembre dernier, Apple a une nouvelle fois été mise au parfum par des chercheurs en sécurité anonymes. La firme de Cupertino a mis à jour, ces dernières heures, ses systèmes d'exploitation iOS et iPadOS, afin de corriger non pas une, ni deux, mais trois nouvelles failles de sécurité de type zero-day.

Depuis quelques semaines, macOS Big Sur souffre d'un bug pouvant entraîner de graves pertes de données. Le problème est arrivé avec la version 11.2 de l'OS, et s'est poursuivi dans la version 11.3.
Le problème ? L'installateur de macOS Big Sur ne vérifie pas si le Mac dispose de l'espace libre nécessaire pour effectuer une mise à niveau. La mise à jour peut alors rencontrer des problèmes et, comme si cela ne suffisait pas, si l'utilisateur a chiffré son Mac à l'aide de FileVault, alors il se retrouve sans ses données.
Oui, c'est effrayant.
Un correctif a été publié par Apple Le bug est détaillé par Mr Macintosh, qui met en évidence le problème et quelques solutions possibles, notamment à travers une vidéo très informative et détaillée. Les utilisateurs concernés par ce bug disposaient de plus de 13 Go d'espace libre, mais de moins de 35,5 Go.

Apple, rather unusually in today’s cybersecurity world, rarely announces that security fixes are on the way.
There’s no equivalent of Microsoft’s Patch Tuesday, which is a regular and predictable fixture in anyone’s cybersecurity calendar; there’s no “new version every fourth Tuesday” as there is with Firefox; there’s no predetermined quarterly schedule for patches as you get with Oracle’s products.
Apple’s approach is to keep everything under wraps until a working update is ready, and then to announce its patches at the same time that they are available for download:
Apple doesn’t disclose, discuss or confirm security issues until an investigation has occurred and patches or releases are generally available.
Interestingly, Apple says that the official reason for doing it this way, rather than having a more regular process that you can plan around, is: “For the protection of our customers. Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/apple-mac-ios4-ipad-iphone-and-in-security

For more than five years, macOS users have been the targets of a sneaky malware operation that used a clever trick to avoid detection and hijacked the hardware resources of infected users to mine cryptocurrency behind their backs
Named OSAMiner, the malware has been distributed in the wild since at least 2015 disguised in pirated (cracked) games and software such as League of Legends and Microsoft Office for Mac, security firm SentinelOne said in a report published this week.
"OSAMiner has been active for a long time and has evolved in recent months," a SentinelOne spokesperson told ZDNet in an email interview on Monday.
"From what data we have it appears to be mostly targeted at Chineses/Asia-Pacific communities," the spokesperson added. Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/apple-mac-ios4-ipad-iphone-and-in-security

Apple a publié aujourd'hui des mises à jour de sécurité pour iOS afin de corriger trois vulnérabilités de type "zero-day" qui ont été découvertes lors d'attaques contre ses utilisateurs.
Selon Shane Huntley, directeur du groupe d'analyse des menaces de Google, ces trois failles zero-day d'iOS sont liées à la récente découverte de trois autres failles zero-day dans Chrome [1, 2, 3] et d'une faille zero-day de Windows, divulguées par Google au cours des dernières semaines.
Tout comme dans les quatre cas précédents, Google n'a pas communiqué de détails sur le ou les attaquants ou leur(s) cible(s). Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/apple-mac-ios4-ipad-iphone-and-in-security

Cela fait quelques années qu'un certain nombre de hackers travaillent sur le mécanisme interne du silicium personnalisé, qui est installé dans les derniers Macs. Ils ont découvert qu'il est possible de pirater la puce de sécurité T2 des récents Mac en combinant des exploits développés afin de pouvoir pirater des téléphones plus anciens. Rick Mark, chercheur en sécurité belge travaillant chez IronPeak, a indiqué que la puce T2 est basée sur l'ancien processeur Apple de la série A10. Cela signifie que l'on peut combiner un exploit développé pour le jailbreaking de l'iPhone, « checkm8 », avec une vulnérabilité du contrôleur mémoire appelée « blackbird ». Cette technique permet non seulement de modifier son comportement, mais aussi d’installer un malware sur la puce.

Apple has released security updates to patch three zero-day vulnerabilities that attackers might have exploited in the wild.
In all three cases, Apple said that it is aware of reports that the security issues "may have been actively exploited," but it didn't provide details on the attacks or threat actors who may have exploited the zero-days.
Exploitable for privacy bypass and code execution Two of the three zero-days (tracked as CVE-2021-30663 and CVE-2021-30665) impact WebKit on Apple TV 4K and Apple TV HD devices. Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/apple-mac-ios4-ipad-iphone-and-in-security

It’s only a week since Apple’s last product updates, but it’s already time to update again.
As you probably know, Apple, unusually amongst major operating system and application producers, doesn’t have any sort of predictable schedule for its security patches.
Unlike vendors such as Microsoft (monthly), Google Android (monthly) and Mozilla (every fourth Tuesday), security updates emerge from Cupertino HQ whenever Apple thinks the time is right.
And unlike Linux, where updates come thick and fast but you can at least track the issues that are being worked on at any moment, Apple’s updates arrive not only as-and-when, but also under an official cloak of undisclosure:

The latest version of Apple's macOS comes with more than just a slew of fancy new features.
Buried inside macOS 11.3, which was released Monday morning, is a patch that fixes a critical vulnerability that was actively being exploited. This means that, yes, hackers or criminals or governments around the world were using this previously unreported bug for their own malicious ends.
That's according to Patrick Wardle, creator of the Mac security website and tool suite Objective-See. In a blog post timed to coincide with the release of macOS 11.3, Wardle explains just how serious the now-patched vulnerability is.
"This bug trivially bypasses many core Apple security mechanisms, leaving Mac users at grave risk," he writes.
Worryingly, Wardle and Jamf, a company that makes Apple management software for enterprise customers, were able to detect real malware exploiting this bug in the wild.
We reached out to Apple to both confirm Wardle's report and that macOS 11.3 contains a patch for this specific vulnerability. An Apple spokesperson confirmed that the latest version of macOS does include a fix for the underlying issues.

A second malware that targets Macs with Apple’s in-house M1 chip is infecting machines worldwide — but it’s unclear why.
Hard on the heels of a macOS adware being recompiled to target Apple’s new in-house processor, researchers have discovered a brand-new family of malware targeting the platform.
Curiously, in the samples seen so far by analysts at Red Canary, the malware (dubbed Silver Sparrow) has been executing on victim machines with the final payload yet to be determined. It appears to be lying in wait for further instructions, which is worrying because it’s clear that the authors are advanced and sophisticated adversaries, researchers said.
Silver Sparrow has taken flight in any event: As of February 17, this fresh entry to the malware scene had already infected 29,139 macOS endpoints across 153 countries, according to researchers – primarily in Canada, France, Germany, the United Kingdom and the United States.

The first malware native to Apple Silicon M1 Macs has been discovered by independent security researcher Patrick Wardle.
Ex-NSA researcher Patrick Wardle has recently praised Apple for the security of its M1 processor, but even so has now discovered evidence of hackers recompiling malware for it.
Wardle discovered the existence of GoSearch22.app, an M1-native version of the longstanding Pirrit virus. This version appears to have been aimed at displaying ads and collecting data from the user's browser.
"Today we confirmed that malicious adversaries are indeed crafting multi-architecture applications, so that their code will natively run on M1 systems," says Wardle in a blog post. "The malicious GoSearch22 application may be the first example of such natively M1 compatible code."

For the past few weeks, macOS Big Sur has suffered from a bug that could cause serious data loss. The bug was introduced in Big Sur 11.2, and it made its way into the 11.3 data.
The bug comes down to the macOS Big Sur installer not checking if the Mac has the required free space available to carry out an upgrade. The upgrade runs into problems, and if that isn't bad enough, if the user's Mac was encrypted using FileVault, then the user is locked out of their data.
Pretty scary stuff.
The bug has been explored extensively by Mr. Macintosh, outlining the problem, some possible solutions, along with a very informative and detailed video. The bug was narrowed down to an evil Goldilocks zone, where users had more than 13GB of free space, but less than 35.5GB.
The video is truly awesome work. Thank you Mr. Macintosh for your work! Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/apple-mac-ios4-ipad-iphone-and-in-security

Am späten Donnerstag kam es bei zahlreichen Mac-Nutzern zu einem schwerwiegenden Problem: Apps wollten nicht mehr laden und starten oder agierten unendlich langsam. Selbst Neustarts halfen nichts, weil dann wiederum Programme, die normalerweise im Hintergrund laufen, nicht korrekt hochfahren wollten. Betroffen waren alle aktuellen Betriebssysteme, also auch ältere wie macOS 10.14 und 10.15 (Mojave und Catalina). Mancher glaubte schon, der Rechner oder dessen SSD sei hinüber. Doch merkwürdigerweise legte sich das unschöne Verhalten, sobald man den Mac vom Netz trennte, also etwa die WLAN-Unterstützung abschaltete.
Wie Entwickler und Hacker jedoch schnell auf Twitter und anderen Plattformen zusammentrugen, handelte es sich keineswegs um ein Hardware-Problem. Stattdessen streikte ein bestimmter Server bei Apple, der zur Signaturüberprüfung dient. Der Daemon trustd, der Apples OCSP-Server (Online Certificate Status Protocol) abfragt, bekam offenbar keine Antwort.
