2023-04-11 15:22:39 | Restrictions d'exploitation Java dans les temps JDK modernes Java Exploitation Restrictions in Modern JDK Times (lien direct) |
Java deserialization gadgets have a long history in context of vulnerability research and at least go back to the year 2015. One of the most popular tools providing a large set of different gadgets is ysoserial by Chris Frohoff. Recently, we observed increasing concerns from the community why several gadgets do not seem to work anymore with more recent versions of JDKs. In this blog post we try to summarize certain facts to reenable some capabilities which seemed to be broken. But our journey did not begin with deserialization in the first place but rather looking for alternative ways of executing Java code in recent JDK versions. In this blost post, we\'ll focus on OpenJDK and Oracle implementations. Defenders should therefore adjust their search patterns to these alternative code execution patterns accordingly.ScriptEngineManager - It\'s GoneInitially, our problems began on another exploitation track not related to deserialization. Often code execution payloads in Java end with a final call to java.lang.Runtime.getRuntime().exec(args), at least in a proof-of-concept exploitation phase. But as a Red Team, we always try to maintain a low profile and avoid actions that may raise suspicion like spawing new (child) processes. This is a well-known and still hot topic discussed in the context of C2 frameworks today, especially when it comes to AV/EDR evasion techniques. But this can also be applied to Java exploitation. It is a well-known fact that an attacker has the choice between different approaches to stay within the JVM to execute arbitrary Java code, with new javax.script.ScriptEngineManager().getEngineByName(engineName).eval(scriptCode) probably being the most popular one over the last years. The input code used is usually based on JavaScript being executed by the referenced ScriptEngine available, e.g. Nashorn (or Rhino).But since Nashorn was marked as deprecated in Java 11 (JEP 335), and removed entirely in Java 15 (JEP 372), this means that a target using a JDK version >= 15 won\'t process JavaScript payloads anymore by default. Instead of hoping for other manually added JavaScript engines by developers for a specific target, we could make use of a "new" Java code evaluation API: JShell, a read-eval-print loop (REPL) tool that was introduced with Java 9 (JEP 222). Mainly used in combination with a command line interface (CLI) for testing Java code snippets, it allows programmatic access as well (see JShell API). This new evaluation call reads like jdk.jshell.JShell.create().eval(javaCode), executing Java code snippets (not JavaScript!). Further call variants exist, too. We found this being mentioned already in 2019 used in context of a SpEL Injection payload. This all sounded to good to be true but nevertheless some restrictions seemed to apply. "The input should be exactly one complete snippet of source code, that is, one expression, statement, variable declaration, method declaration, class declaration, or import." So, we started to play with some Java code snippets using the JShell API. First, we realized that it is indeed possible to use import statements within such snippets but interestingly the subsequent statements were not executed anymore. This should have been expected by re | Tool Vulnerability | ★★ | |

[The New Face of Fraud] FTC Sheds Light on AI-Enhanced Family Emergency Scams
The Federal Trade Commission is alerting consumers about a next-level, more sophisticated family emergency scam that uses AI which imitates the voice of a "family member in distress."
They started out with: "You get a call. There\'s a panicked voice on the line. It\'s your grandson. He says he\'s in deep trouble - he wrecked the car and landed in jail. But you can help by sending money. You take a deep breath and think. You\'ve heard about grandparent scams. But darn, it sounds just like him. How could it be a scam? Voice cloning, that\'s how."
"Don\'t Trust The Voice"
The FTC explains: "Artificial intelligence is no longer a far-fetched idea out of a sci-fi movie. We\'re living with it, here and now. A scammer could use AI to clone the voice of your loved one. All he needs is a short audio clip of your family member\'s voice - which he could get from content posted online - and a voice-cloning program. When the scammer calls you, he\'ll sound just like your loved one.
"So how can you tell if a family member is in trouble or if it\'s a scammer using a cloned voice? Don\'t trust the voice. Call the person who supposedly contacted you and verify the story. Use a phone number you know is theirs. If you can\'t reach your loved one, try to get in touch with them through another family member or their friends."

2023-04-11 12:11:33 | Annonce de l'API DEPS.DEV: données de dépendance critiques pour les chaînes d'approvisionnement sécurisées Announcing the deps.dev API: critical dependency data for secure supply chains (lien direct) |
Posted by Jesper Sarnesjo and Nicky Ringland, Google Open Source Security Team Today, we are excited to announce the deps.dev API, which provides free access to the deps.dev dataset of security metadata, including dependencies, licenses, advisories, and other critical health and security signals for more than 50 million open source package versions. Software supply chain attacks are increasingly common and harmful, with high profile incidents such as Log4Shell, Codecov, and the recent 3CX hack. The overwhelming complexity of the software ecosystem causes trouble for even the most diligent and well-resourced developers. We hope the deps.dev API will help the community make sense of complex dependency data that allows them to respond to-or even prevent-these types of attacks. By integrating this data into tools, workflows, and analyses, developers can more easily understand the risks in their software supply chains. The power of dependency data As part of Google\'s ongoing efforts to improve open source security, the Open Source Insights team has built a reliable view of software metadata across 5 packaging ecosystems. The deps.dev data set is continuously updated from a range of sources: package registries, the Open Source Vulnerability database, code hosts such as GitHub and GitLab, and the software artifacts themselves. This includes 5 million packages, more than 50 million versions, from the Go, Maven, PyPI, npm, and Cargo ecosystems-and you\'d better believe we\'re counting them! We collect and aggregate this data and derive transitive dependency graphs, advisory impact reports, OpenSSF Security Scorecard information, and more. Where the deps.dev website allows human exploration and examination, and the BigQuery dataset supports large-scale bulk data analysis, this new API enables programmatic, real-time access to the corpus for integration into tools, workflows, and analyses. The API is used by a number of teams internally at Google to support the security of our own products. One of the first publicly visible uses is the GUAC integration, which uses the deps.dev data to enrich SBOMs. We have more exciting integrations in the works, but we\'re most excited to see what the greater open source community builds! We see the API as being useful for tool builders, researchers, and tinkerers who want to answer questions like: What versions are available for this package? What are the licenses that cover this version of a package-or all the packages in my codebase? How many dependencies does this package have? What are they? Does the latest version of this package include changes to dependencies or licenses? What versions of what packages correspond to this file? Taken together, this information can help answer the most important overarching question: how much risk would this dependency add to my project? The API can help surface critical security information where and when developers can act. This data can be integrated into: IDE Plugins, to make dependency and security information immediately available. CI | Tool Vulnerability | ★★ | |

2023-04-03 10:00:00 | 10 raisons pour lesquelles les entreprises ont besoin de gestion des appareils mobiles (MDM) 10 Reasons why businesses need mobile device management (MDM) (lien direct) |
The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. Mobile device management (MDM) refers to a type of software that allows businesses to manage, configure and secure mobile devices used by their employees. Companies use MDM solutions to maintain a secure environment across all the mobile devices they own or have access to, as well as provide features such as remote wipe, password policies, application management and data protection. This helps them ensure security while providing their employees with access to the applications and data they need. An increasing number of businesses are either accepting that they need MDM or realising that what they have in place is not sufficient. With that in mind, below are ten reasons why MDM is an integral part of doing business in the 21st century. 1. Enhanced security MDM technology provides an extra layer of security for businesses, protecting them from breaches and data loss. MDM solutions enable secure authentication, access control and encryption for devices, applications and data, which in turn helps to keep sensitive corporate information safe. ESIMs, or embedded SIM cards can enhance the security of mobile devices even further by allowing businesses to remotely manage and secure their devices. Improved security is one of the most important reasons why businesses need MDM solutions. With an ever-increasing number of cyber threats, it is essential for companies to take steps to keep their data and systems secure. MDM can help with this. 2. Increased productivity MDM makes it easier for employees to access the applications and data they need, increasing their productivity and efficiency. By providing them with secure access to the resources they need, MDM solutions help remove the frustration of not being able to do their job due to technical issues or security policies. The ability to securely access corporate resources from anywhere, at any time, helps boost employee productivity and gives them the freedom they need to work more flexibly. 3. Reduced costs MDM solutions can help reduce costs in several ways. They enable companies to better manage their mobile devices and applications, which ensures that they are up-to-date with the latest security patches and features. This helps reduce maintenance costs associated with managing outdated equipment. MDM solutions also make it easier for businesses to deploy new applications, as they don’t have to worry about manually configuring each device. This reduces expensive install times and makes it easier for employees to get started quickly. 4. Improved compliance MDM solutions help businesses comply with industry standards and regulations. They enable companies to configure devices to meet specific security requirements, as well as monitor and manage mobile devices so that they adhere to corporate policies. By ensuring that all company devices are configured securely, MDM solutions reduce the risk of data breaches and fines associated with non-compliance. What\'s more, they can help identify areas where businesses need to improve their compliance processes. 5. Easier troubleshooting MDM solutio | Tool | ★★ | |

campagne de phishingCible l'industrie chinoise de l'énergie nucléaire
(Publié: 24 mars 2023)
Actif Depuis 2013, le groupe amer (T-APT-17) est soupçonné d'être parrainé par le gouvernement indien.Des chercheurs Intezer ont découvert une nouvelle campagne amère ciblant les universitaires, le gouvernement et d'autres organisations de l'industrie de l'énergie nucléaire en Chine.Les techniques sont cohérentes avec les campagnes amères observées précédemment.L'intrusion commence par un e-mail de phishing censé provenir d'un véritable employé de l'ambassade du Kirghizistan.Les pièces jointes malveillantes observées étaient soit des fichiers HTML (CHM) compilés à Microsoft, soit des fichiers Microsoft Excel avec des exploits d'éditeur d'équation.L'objectif des charges utiles est de créer de la persistance via des tâches planifiées et de télécharger d'autres charges utiles de logiciels malveillants (les campagnes amères précédentes ont utilisé le voleur d'identification du navigateur, le voleur de fichiers, le keylogger et les plugins d'outils d'accès à distance).Les attaquants se sont appuyés sur la compression LZX et la concaténation des cordes pour l'évasion de détection.
Commentaire de l'analyste: De nombreuses attaques avancées commencent par des techniques de base telles que des e-mails injustifiés avec une pièce jointe qui oblige l'utilisateur à l'ouvrir.Il est important d'enseigner l'hygiène de base en ligne à vos utilisateurs et la sensibilisation au phishing.Il est sûr de recommander de ne jamais ouvrir de fichiers CHM joints et de garder votre bureau MS Office entièrement mis à jour.Tous les indicateurs connus associés à cette campagne amère sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

[Eye Opener] How to Outsmart Sneaky AI-Based Phishing Attacks
Users need to adapt to an evolving threat landscape in which attackers can use AI tools like ChatGPT to craft extremely convincing phishing emails, according to Matthew Tyson at CSO.
"A leader tasked with cybersecurity can get ahead of the game by understanding where we are in the story of machine learning (ML) as a hacking tool," Tyson writes. "At present, the most important area of relevance around AI for cybersecurity is content generation.
"This is where machine learning is making its greatest strides and it dovetails nicely for hackers with vectors such as phishing and malicious chatbots. The capacity to craft compelling, well-formed text is in the hands of anyone with access to ChatGPT, and that\'s basically anyone with an internet connection."
Tyson quotes Conal Gallagher, CIO and CISO at Flexera, as saying that since attackers can now write grammatically correct phishing emails, users will need to pay attention to the circumstances of the emails.
"Looking for bad grammar and incorrect spelling is a thing of the past - even pre-ChatGPT phishing emails have been getting more sophisticated," Gallagher said. "We must ask: \'Is the email expected? Is the from address legit? Is the email enticing you to click on a link?\' Security awareness training still has a place to play here."
Tyson explains that technical defenses have become very effective, so attackers focus on targeting humans to bypass these measures.
"Email and other elements of software infrastructure offer built-in fundamental security that largely guarantees we are not in danger until we ourselves take action," Tyson writes. "This is where we can install a tripwire in our mindsets: we should be hyper aware of what it is we are acting upon when we act upon it.
"Not until an employee sends a reply, runs an attachment, or fills in a form is sensitive information at risk. The first ring of defense in our mentality should be: \'Is the content I\'m looking at legit, not just based on its internal aspects, but given the entire context?\' The second ring of defense in our mentality then has to be, \'Wait! I\'m being asked to do something here.\'"
New-school security awareness training with simulated phishing tests enables your employees to recognize increasingly sophisticated phishing attacks and builds a strong security culture.
Remember: Culture eats strategy for breakfast and is always top-down.

2023-03-24 00:00:00 | Pourquoi les petites entreprises devraient apprendre les compétences nécessaires pour améliorer leur cybersécurité Why Small Businesses should Learn the Skills to Improve their Cybersecurity (lien direct) |
Comme présenté dans le Supplement Irish Independent Business Resilience
Toutes les entreprises courent un risque important de cyberattaque - y compris les PME.Cependant, ils peuvent se protéger avec la bonne formation et une approche de cybersécurité plus proactive.
La plupart des petites et moyennes entreprises (PME) ne sont que trop conscientes des risques de cyberattaque, note Donna O \\ 'Shea, présidente de la cybersécurité à Munster Technological University (MTU) et le chef de projet à Cyber Skills - un projet financé à l'échelle nationalequi vise à répondre à la pénurie de compétences en cybersécurité.
Les menaces de cybersécurité croissantes pour les PME
Selon le Cybersecurity Consortium Pmesec, 60% de toutes les cyberattaques en 2016 étaient destinées aux petites entreprises.Ce qui est de plus, 60% des PME qui ont été victimes d'attaques ne se sont pas rétablies et ont fermé dans les six mois.Malgré ces statistiques, les PME ne traitent pas toujours correctement les questions de cybersécurité - et pour diverses raisons.
«Certains propriétaires d'entreprise peuvent manquer de confiance et de capacités techniques pour répondre aux risques de cybersécurité», explique O \\ 'Shea.«D'autres minimisent le problème et demandent: \\ 'Qui essaierait de pirater mon entreprise de toute façon? \' Mais si leur base de données de clients \\ 'Informations personnelles subit une violation, c'est un problème majeur de conformité du RGPD.»
Il y a aussi beaucoup de dissonance cognitive entourant ce sujet, admet O \\ 'Shea.«Il y a une tendance à penser aux PME: \\ 'Oui, notre entreprise est en danger - mais nous allons l'oublier. \' Nous devons changer leur état d'esprit pour: \\ 'Oui, notre entreprise est en danger - mais nous pouvons y répondre correctement avec les bonnes compétences et la bonne formation. »
Retirer la mystique autour de la cybersécurité
Cyber Skills a développé la cybersécurité pour les entreprises - une série d'ateliers relatable livrée par des experts de l'industrie.Cela a été conçu pour fournir aux propriétaires d'entreprise les connaissances et les compétences clés pour se protéger contre les cyberattaques et supprimer une partie de la mystique entourant le sujet.
Être proactif sur la cybersécurité
Depuis trop longtemps, les entreprises ont adopté une approche \\ 'défensive et réactionnaire de la cybersécurité - avec des pare-feu, des systèmes de détection d'intrusion et des anti-virus faisant tout le gros du travail.Bien que ce soient toutes des mesures de sécurité importantes à avoir mis en place, au moment où un système réagit à une violation, les dommages ont déjà été causés.
«Au lieu de cela, nous exhortons les entreprises à adopter une approche prédictive et réactive de la cybersécurité», explique O \\ 'Shea.«Les ateliers les aident à identifier où se trouvent leurs plus grands risques d'attaque.Nous appliquons des modèles, des outils et des techniques bien connus et montrons aux PME comment créer un plan de réponse aux incidents et un plan de continuité des activités - adapté à leurs besoins - de sorte que, en cas d'attaque, ils peuvent se remettre en service aussi rapidement aussi rapidementcomme possible.En fin de compte, les entreprises doivent commencer à penser à la cybersécurité d'une manière plus structurée et proactive. »

2023-03-23 10:00:00 | Blackguard Stealer étend ses capacités dans une nouvelle variante [BlackGuard stealer extends its capabilities in new variant] (lien direct) | AT&T Alien Labs researchers have discovered a new variant of BlackGuard stealer in the wild, infecting using spear phishing attacks. The malware evolved since its previous variant and now arrives with new capabilities.
Key takeaways:
BlackGuard steals user sensitive information from a wide range of applications and browsers.
The malware can hijack crypto wallets copied to clipboard.
The new variant is trying to propagate through removable media and shared devices.
Background
BlackGuard stealer is malware as a service sold in underground forums and Telegram since 2021, when a Russian user posted information about a new malware called BlackGuard. It was offered for $700 lifetime or $200 monthly, claiming it can collect information from a wide range of applications and browsers.
In November 2022, an update for BlackGuard was announced in Telegram by its developer. Along with the new features, the malware author suggests free help with installing the command & control panel (Figure 1)
Figure 1. Announcement of new malware version in its Telegram channel.
Analysis
When executed, BlackGuard first checks if another instance is running by creating a Mutex.
Then to ensure it will survive a system reboot, the malware adds itself to the “Run” registry key. The malware also checks if it\'s running in debugger mode by checking TickCount and checking if the current user belongs to a specific list to determine whether it is running in a malware sandbox environment. (Figure 2)
Figure 2. Malware will avoid execution if running under specific user names.
Now all is ready for stealing the user’s sensitive data. It collects all stolen information in a folder where each piece of data is stored in a specific folder, such as Browsers, Files, Telegram, etc. (Figure 3)
Figure 3. BlackGuard main folder with stolen data divided into folders.
When it finishes collecting sensitive data, the malware will zip the main folder using the password “xNET3301LIVE” and send it to its command & control. (Figure 4)
Figure 4. Zipping exfiltrated data with password and uploading to command & control.
Browser stealth
Along with collecting cookies, history and downloads of different browsers, BlackGuard also looks for the existence of special files and folders of different browsers. (This includes “Login Data”, AutoFill, History and Downloads. (Figure 5)

Below is the list of browsers BlackGuard is looking for:

2023-03-20 12:30:04 | JMX Exploitation Revisited (lien direct) | The Java Management Extensions (JMX) are used by many if not all enterprise level applications in Java for managing and monitoring of application settings and metrics. While exploiting an accessible JMX endpoint is well known and there are several free tools available, this blog post will present new insights and a novel exploitation technique that allows for instant Remote Code Execution with no further requirements, such as outgoing connections or the existence of application specific MBeans. Introduction How to exploit remote JMX services is well known. For instance, Attacking RMI based JMX services by Hans-Martin Münch gives a pretty good introduction to JMX as well as a historical overview of attacks against exposed JMX services. You may want to read it before proceeding so that we're on the same page. And then there are also JMX exploitation tools such as mjet (formerly also known as sjet, also by Hans-Martin Münch) and beanshooter by my colleague Tobias Neitzel, which both can be used to exploit known vulnerabilities and JMX services and MBeans. However, some aspects are either no longer possible in current Java versions (e. g., pre-authenticated arbitrary Java deserialization via RMIServer.newClient(Object)) or they require certain MBeans being present or conditions such as the server being able to connect back to the attacker (e. g., MLet with HTTP URL). In this blog post we will look into two other default MBean classes that can be leveraged for pretty unexpected behavior: remote invocation of arbitrary instance methods on arbitrary serializable objects remote invocation of arbitrary static methods on arbitrary classes Tobias has implemented some of the gained insights into his tool beanshooter. Thanks! Read The Fine Manual By default, MBean classes are required to fulfill one of the following: follow certain design patterns implement certain interfaces For example, the javax.management.loading.MLet class implements the javax.management.loading.MLetMBean, which fulfills the first requirement that it implements an interface whose name of the same name but ends with MBean. The two specific MBean classes we will be looking at fulfill the second requirement: javax.management.StandardMBean javax.management.modelmbean.RequiredModelMBean Both classes provide features that don't seem to have gotten much attention yet, but are pretty powerful and allow interaction with the MBean server and MBeans that may even violate the JMX specification. The Standard MBean Class StandardMBean The StandardMBean was added to JMX 1.2 with the following description: […] the javax.management.StandardMBean class can be used to define standard MBeans with an interface whose name is not necessarily related to the class name of the MBean. – Java™ Management Extensions (JMX™) (Maintenance Release 2) Also: An MBean whose management interface is determined by reflection on a Java interface. – | Tool | ★★ | |

Xenomorph V3: a New Variant with ATS Targeting More Than 400 Institutions
(published: March 10, 2023)
Newer versions of the Xenomorph Android banking trojan are able to target 400 applications: cryptocurrency wallets and mobile banking from around the World with the top targeted countries being Spain, Turkey, Poland, USA, and Australia (in that order). Since February 2022, several small, testing Xenomorph campaigns have been detected. Its current version Xenomorph v3 (Xenomorph.C) is available on the Malware-as-a-Service model. This trojan version was delivered using the Zombinder binding service to bind it to a legitimate currency converter. Xenomorph v3 automatically collects and exfiltrates credentials using the ATS (Automated Transfer Systems) framework. The command-and-control traffic is blended in by abusing Discord Content Delivery Network.
Analyst Comment: Fraud chain automation makes Xenomorph v3 a dangerous malware that might significantly increase its prevalence on the threat landscape. Users should keep their mobile devices updated and avail of mobile antivirus and VPN protection services. Install only applications that you actually need, use the official store and check the app description and reviews. Organizations that publish applications for their customers are invited to use Anomali's Premium Digital Risk Protection service to discover rogue, malicious apps impersonating your brand that security teams typically do not search or monitor.

2023-03-08 12:04:53 | OSV and the Vulnerability Life Cycle (lien direct) | Posted by Oliver Chang and Andrew Pollock, Google Open Source Security Team It is an interesting time for everyone concerned with open source vulnerabilities. The U.S. Executive Order on Improving the Nation's Cybersecurity requirements for vulnerability disclosure programs and assurances for software used by the US government will go into effect later this year. Finding and fixing security vulnerabilities has never been more important, yet with increasing interest in the area, the vulnerability management space has become fragmented-there are a lot of new tools and competing standards. In 2021, we announced the launch of OSV, a database of open source vulnerabilities built partially from vulnerabilities found through Google's OSS-Fuzz program. OSV has grown since then and now includes a widely adopted OpenSSF schema and a vulnerability scanner. In this blog post, we'll cover how these tools help maintainers track vulnerabilities from discovery to remediation, and how to use OSV together with other SBOM and VEX standards. Vulnerability Databases The lifecycle of a known vulnerability begins when it is discovered. To reach developers, the vulnerability needs to be added to a database. CVEs are the industry standard for describing vulnerabilities across all software, but there was a lack of an open source centric database. As a result, several independent vulnerability databases exist across different ecosystems. To address this, we announced the OSV Schema to unify open source vulnerability databases. The schema is machine readable, and is designed so dependencies can be easily matched to vulnerabilities using automation. The OSV Schema remains the only widely adopted schema that treats open source as a first class citizen. Since becoming a part of OpenSSF, the OSV Schema has seen adoption from services like GitHub, ecosystems such as Rust and Python, and Linux distributions such as Rocky Linux. Thanks to such wide community adoption of the OSV Schema, OSV.dev is able to provide a distributed vulnerability database and service that pulls from language specific authoritative sources. In total, the OSV.dev database now includes 43,302 vulnerabilities from 16 ecosystems as of March 2023. Users can check OSV for a comprehensive view of all known vulnerabilities in open source. Every vulnerability in OSV.dev contains package manager versions and git commit hashes, so open source users can easily determine if their packages are impacted because of the familiar style of versioning. Maintainers are also familiar with OSV's community driven and distributed collaboration on the development of OSV's database, tools, and schema. Matching The next step in managing vulnerabilities is to determine project dependencies and their associated vulnerabilities. Last December we released OSV-Scanner, a free, open source tool which scans software projects' lockfiles, SBOMs, or git repositories to identify vulnerabilities found in the | Tool Vulnerability | ★★★★ | |

2023-03-08 11:59:13 | Thank you and goodbye to the Chrome Cleanup Tool (lien direct) | Posted by Jasika Bawa, Chrome Security Team Starting in Chrome 111 we will begin to turn down the Chrome Cleanup Tool, an application distributed to Chrome users on Windows to help find and remove unwanted software (UwS). Origin story The Chrome Cleanup Tool was introduced in 2015 to help users recover from unexpected settings changes, and to detect and remove unwanted software. To date, it has performed more than 80 million cleanups, helping to pave the way for a cleaner, safer web. A changing landscape In recent years, several factors have led us to reevaluate the need for this application to keep Chrome users on Windows safe. First, the user perspective – Chrome user complaints about UwS have continued to fall over the years, averaging out to around 3% of total complaints in the past year. Commensurate with this, we have observed a steady decline in UwS findings on users' machines. For example, last month just 0.06% of Chrome Cleanup Tool scans run by users detected known UwS. Next, several positive changes in the platform ecosystem have contributed to a more proactive safety stance than a reactive one. For example, Google Safe Browsing as well as antivirus software both block file-based UwS more effectively now, which was originally the goal of the Chrome Cleanup Tool. Where file-based UwS migrated over to extensions, our substantial investments in the Chrome Web Store review process have helped catch malicious extensions that violate the Chrome Web Store's policies. Finally, we've observed changing trends in the malware space with techniques such as Cookie Theft on the rise – as such, we've doubled down on defenses against such malware via a variety of improvements including hardened authentication workflows and advanced heuristics for blocking phishing and social engineering emails, malware landing pages, and downloads. What to expect Starting in Chrome 111, users will no longer be able to request a Chrome Cleanup Tool scan through Safety Check or leverage the "Reset settings and cleanup" option offered in chrome://settings on Windows. Chrome will also remove the component that periodically scans Windows machines and prompts users for cleanup should it find anything suspicious. Even without the Chrome Cleanup Tool, users are automatically protected by Safe Browsing in Chrome. Users also have the option to turn on Enhanced protection by navigating to chrome://settings/security – this mode substantially increases protection from dangerous websites and downloads by sharing real-time data with Safe Browsing. While we'll miss the Chrome Cleanup Tool, we wanted to take this opportunity to acknowledge its role in combating UwS for the past 8 years. We'll continue to monitor user feedback and trends in the malware ecosystem, and when adversaries adapt their techniques again – which they will – we'll be at the ready. As always, please feel free to send us feedback or find us on Twitter @googlechrome. | Malware Tool | ★★★ |
