Spear Phishing Attacks Target Organizations in Ukraine, Payloads Include the Document Stealer OutSteel and the Downloader SaintBot
(published: February 25, 2022)
Researchers at Unit 42 identified an attack targeting an energy organization in Ukraine. Ukrainian CERT has attributed this attack to a threat group they track as UAC-0056. The targeted attack involved a spear phishing email sent to organization employees containing a malicious JavaScript file that would download and install a downloader known as SaintBot and a document stealer called OutSteel. Actors leverage Discord’s content delivery network (CDN) to host their payload. Goal of this attack was data collection on government organizations and companies involved with critical infrastructure.
Analyst Comment: Administrators can block traffic to discordapp[.]com if their organization doesn’t have a current legitimate use of Discord. Implement attack surface reduction rules for Microsoft Office. Train users to recognize, safely process, and report potential spearphishing emails.

2022-03-01 09:16:53 | Remote Utilities Software Distributed in Ukraine via Fake Evacuation Plan Email (lien direct) | FortiGuard Labs is aware that a copy of Remote Manipulator System (RMS) was submitted from Ukraine to VirusTotal on February 28th, 2022. The RMS is a legitimate remote administration tool that allows a user to remotely control another computer. The file name is in Ukrainian and is "Evacuation Plan (approved by the SSU on 28.02.2022 by Order No. 009363677833).exe" in translation to English. The SSU likely stands for the Security Service of Ukraine. Why is this Significant?This is significant because given its file name, the country where the file was submitted to VirusTotal and the current situation in Ukraine, the file may have been distributed to Ukrainians.What does the File Do?The file silently installs a copy of legitimate Remote Utilities software to the compromised machine. The software allows a remote user to control the compromised machine.Based on the telemetry FortiGuard Labs collected, there is one IP address in Ukraine that connected to the remote IP that likely belongs to the attacker. How was the File Distributed to the Targets?Most likely via links in email.CERT-UA published a warning today that "the representatives of the Center for Combating Disinformation began to receive requests for information from the mail of the Ukrainian Security Service. Such notifications are fake and are a cyberattack". The email below is reported have been used in the attack.Machine translation:Email subject: Evacuation plan from: SBU (Urgent) -28.02.2022 day off: 534161WARNING! This is an external sheet: do not click on the links or open a tab if you do not trust the editor.Report a suspicious list to ib@gng.com.ua.Security Service of UkraineGood afternoon, you need to have acquainted with the electronic evacuation plan until 01.03.2022, to give data on the number of employees, fill in the document in accordance with Form 198\00-22SBU-98.To ensure confidentiality of the transferred data, the password: 2267903645 is set on the deposit.See the document on:hxxps://mega.nz/file/[reducted]Mirror 2: hxxps://files.dp.ua/en/[reducted]Mirror 3: hxxps://dropmefiles.com/[reducted]While the remote files were not available at the time of the investigation, the email and "Evacuation Plan (approved by the SSU on 28.02.2022 by Order No. 009363677833).exe" are likely connected based on the email content and the file name. Can the File Attributed to a Particular Threat Actor?It's possible that a threat actor distributed the file to target Ukraine. However, while the Remote Utilities software is silently installed on the compromised machine, it displays an icon in Windows's taskbar. Since most threat actors aim to hide their activities, this is potentially an act of novice attacker who tries to take advantage of the current situation in Ukraine.What is the Status of Coverage?FortiGuard Labs provides the following AV coverage against the files involved in this attack:Riskware/RemoteAdmin_RemoteUtilities | Tool Threat | ||

2022-02-23 23:15:07 | CVE-2022-23653 (lien direct) | B2 Command Line Tool is the official command line tool for the backblaze cloud storage service. Linux and Mac releases of the B2 command-line tool version 3.2.0 and below contain a key disclosure vulnerability that, in certain conditions, can be exploited by local attackers through a time-of-check-time-of-use (TOCTOU) race condition. The command line tool saves API keys (and bucket name-to-id mapping) in a local database file (`$XDG_CONFIG_HOME/b2/account_info`, `~/.b2_account_info` or a user-defined path) when `b2 authorize-account` is first run. This happens regardless of whether a valid key is provided or not. When first created, the file is world readable and is (typically a few milliseconds) later altered to be private to the user. If the directory is readable by a local attacker and the user did not yet run `b2 authorize-account` then during the brief period between file creation and permission modification, a local attacker can race to open the file and maintain a handle to it. This allows the local attacker to read the contents after the file after the sensitive information has been saved to it. Users that have not yet run `b2 authorize-account` should upgrade to B2 Command-Line Tool v3.2.1 before running it. Users that have run `b2 authorize-account` are safe if at the time of the file creation no other local users had read access to the local configuration file. Users that have run `b2 authorize-account` where the designated path could be opened by another local user should upgrade to B2 Command-Line Tool v3.2.1 and remove the database and regenerate all application keys. Note that `b2 clear-account` does not remove the database file and it should not be used to ensure that all open handles to the file are invalidated. If B2 Command-Line Tool cannot be upgraded to v3.2.1 due to a dependency conflict, a binary release can be used instead. Alternatively a new version could be installed within a virtualenv, or the permissions can be changed to prevent local users from opening the database file. | Tool Vulnerability | ||

EvilPlayout: Attack Against Iran’s State Broadcaster
(published: February 18, 2022)
Checkpoint Researchers have released an article detailing their findings regarding a wave of cyber attacks directed at Iranian broadcast infrastructure during late January 2022. IRIB, an Iranian state broadcaster, was compromised, with malicious executables and wipers being responsible for the attack. Said malware had multiple functions, including hijacking of several tv stations to play recordings of political opposition leaders demanding the assassination of Iran’s supreme leader. Additional functionality includes custom backdoors, screenshot capability and several bash scripts to download other malicious executables. The malware appears new, with no previous appearances, nor has there been any actor attribution as of the date of publication.
Analyst Comment: Utilize all telemetry and feed it into a SIEM to help identify malicious activity within your network. Anomali Match can collide this telemetry against global intelligence to assist in identifying malicious indicators within your network. A defense in depth approach will also mitigate the damage any compromises can do to your infrastructure.

Microsoft Teams Targeted With Takeover Trojans
(published: February 17, 2022)
Researchers at Avanan have documented a new phishing technique that threat actors are using that abuses the trust users of Microsoft Teams have for the platform to deliver malware. Threat Actors send phishing links to victims which initiate a chat on the platform, after which they will post a link to a dll file within the chat box. When clicked, it will install a trojan of choice on the target machine. With over 279 million users, this presents a new attack vector for threat actors to abuse.
Analyst Comment: Never click on a link or open attachments from untrusted senders when receiving email. Be skeptical of strangers attempting to move conversation to another platform, even if you use that platform. Be wary of links posted in apps that are used for communication, as links that are posted on trusted platforms are not trustworthy themselves.

Le service repose sur la technologie Endpoint Protection Detection and Response (EPDR) reconnue de WatchGuard Technologies et est opéré par les experts du SOC endpoint d'Ava6, 24h sur 24 et 7 jours sur 7. Avec Red SOC, WatchGuard et Ava6 entendent rendre accessible le SOC endpoint – traditionnellement réservé aux grandes comptes – et l'EDR managé aux PME, ETI et autres collectivités souhaitant renforcer leur niveau de sécurité face aux cyberattaques et notamment les ransomwares. Pascal Le Digol, Country Manager France chez WatchGuard Technologies déclare : " Même si les entreprises ont compris qu'il était urgent de hausser le niveau de sécurité de leur système d'information, elles sont généralement confrontées à plusieurs problématiques. Les PME ont peu de moyens et de ressources à allouer à la cybersécurité, alors que les ETI et les collectivités équipées ou souhaitant s'équiper en EDR managé n'ont pas la capacité de former des équipes de sécurité capables de traiter les nombreuses alertes remontées par les solutions. Avec Ava6, nous avons eu l'idée de créer l'offre Red SOC pour permettre à ces entreprises d'accéder à une solution de sécurité de haut niveau tout en en externalisant la supervision à une équipe de professionnels. Grâce à Red SOC, nous espérons permettre à de nombreuses entreprises et collectivités d'élever leur niveau de sécurité ". Red SOC : Rendre le SOC endpoint et l'EDR managé accessibles au plus grand nombre d'entreprises et de collectivités Red SOC s'articule autour de l'offre logicielle WatchGuard Endpoint Protection Detection and Response (EPDR), et allie technologie et expertise humaine de pointe pour permettre aux entreprises de tirer le meilleur profit de leur solution EDR. La technologie WatchGuard détecte les comportements malveillants susceptibles d'intervenir sur les endpoints (ordinateur de bureau, PC portable, tablette, smartphone et serveur), tandis qu'Ava6 se charge de piloter les actions de remédiation, afin de neutraliser les attaques avant qu'elles ne se propagent dans le système d'information de l'entreprise. La solution WatchGuard joue le rôle de maillon central d'un SOC endpoint car elle collecte, enregistre et agrège les données, à savoir les logs ; une équipe d'experts en sécurité se charge dès lors de délivrer le service permettant de tirer la quintessence de la solution logicielle : en analysant les données et les événements remontés par la solution, les incidents sont qualifiés, ce qui permet d'accélérer la détection ainsi que la remédiation des attaques et autres menaces détectées. Outre la surveillance des endpoints, le suivi et la réponse aux incidents et autres alertes, l'équipe de consultants en sécurité d'Ava6 prend également en charge les mises à jour de la solution WatchGuard et son maintien en conditions de sécurité.

What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors?
(published: February 9, 2022)
A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

Not only have Mandiant\'s incident responders seen ransomware attacks increase dramatically in recent years, ransoms themselves have increased from $416 million for all of 2020 to $590 million for the first six months of 2021, according to the U.S. Treasury. Organizations, large and small, recognize that without the right tools in place they could be the next victim. Threat actors continue to up their game with increasingly aggressive and sophisticated attacks, shifting from standard ransomware |

2022-02-10 20:15:07 | CVE-2022-23630 (lien direct) | Gradle is a build tool with a focus on build automation and support for multi-language development. In some cases, Gradle may skip that verification and accept a dependency that would otherwise fail the build as an untrusted external artifact. This occurs when dependency verification is disabled on one or more configurations and those configurations have common dependencies with other configurations that have dependency verification enabled. If the configuration that has dependency verification disabled is resolved first, Gradle does not verify the common dependencies for the configuration that has dependency verification enabled. Gradle 7.4 fixes that issue by validating artifacts at least once if they are present in a resolved configuration that has dependency verification active. For users who cannot update either do not use `ResolutionStrategy.disableDependencyVerification()` and do not use plugins that use that method to disable dependency verification for a single configuration or make sure resolution of configuration that disable that feature do not happen in builds that resolve configuration where the feature is enabled. | Tool | ||

2022-01-31 15:33:58 | No, a researcher didn\'t find Olympics app spying on you (lien direct) | For the Beijing 2022 Winter Olympics, the Chinese government requires everyone to download an app onto their phone. It has many security/privacy concerns, as CitizenLab documents. However, another researcher goes further, claiming his analysis proves the app is recording all audio all the time. His analysis is fraudulent. He shows a lot of technical content that looks plausible, but nowhere does he show anything that substantiates his claims.Average techies may not be able to see this. It all looks technical. Therefore, I thought I'd describe one example of the problems with this data -- something the average techie can recognize.His "evidence" consists screenshots from reverse-engineering tools, with red arrows pointing to the suspicious bits. An example of one of these screenshots is this on: This screenshot is that of a reverse-engineering tool (Hopper, I think) that takes code and "disassembles" it. When you dump something into a reverse-engineering tool, it'll make a few assumptions about what it sees. These assumptions are usually wrong. There's a process where the human user looks at the analyzed output, does a "sniff-test" on whether it looks reasonable, and works with the tool until it gets the assumptions correct.That's the red flag above: the researcher has dumped the results of a reverse-engineering tool without recognizing that something is wrong in the analysis.It fails the sniff test. Different researchers will notice different things first. Famed google researcher Tavis Ormandy points out one flaw. In this post, I describe what jumps out first to me. That would be the 'imul' (multiplication) instruction shown in the blowup below: It's obviously ASCII. In other words, it's a series of bytes. The tool has tried to interpret these bytes as Intel x86 instructions (like 'and', 'insd', 'das', 'imul', etc.). But it's obviously not Intel x86, because those instructions make no sense.That 'imul' instruction is multiplying something by the (hex) number 0x6b657479. That doesn't look like a number -- it looks like four lower-case ASCII letters. ASCII lower-case letters are in the range 0x61 through 0x7A, so it's not the single 4-byte number 0x6b657479 but the 4 individual bytes 6b 65 74 79, which map to the ASCII letters 'k', 'e', 't |

The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | Tool Vulnerability | ||

2022-01-27 16:00:33 | .NET Remoting Revisited (lien direct) | .NET Remoting is the built-in architecture for remote method invocation in .NET. It is also the origin of the (in-)famous BinaryFormatter and SoapFormatter serializers and not just for that reason a promising target to watch for. This blog post attempts to give insights into its features, security measures, and especially its weaknesses/vulnerabilities that often result in remote code execution. We're also introducing major additions to the ExploitRemotingService tool, a new ObjRef gadget for YSoSerial.Net, and finally a RogueRemotingServer as counterpart to the ObjRef gadget. If you already understand the internal of .NET Remoting, you may skip the introduction and proceed right with Security Features, Pitfalls, and Bypasses. Introduction .NET Remoting is deeply integrated into the .NET Framework and allows invocation of methods across so called remoting boundaries. These can be different app domains within a single process, different processes on the same computer, or different processes on different computers. Supported transports between the client and server are HTTP, IPC (named pipes), and TCP. Here is a simple example for illustration: the server creates and registers a transport server channel and then registers the class as a service with a well-known name at the server's registry: var channel = new TcpServerChannel(12345);ChannelServices.RegisterChannel(channel);RemotingConfiguration.RegisterWellKnownServiceType( typeof(MyRemotingClass), "MyRemotingClass"); Then a client just needs the URL of the registered service to do remoting with the server: var remote = (MyRemotingClass)RemotingServices.Connect( typeof(MyRemotingClass), "tcp://remoting-server:12345/MyRemotingClass"); With this, every invocation of a method or property accessor on remote gets forwarded to the remoting server, executed there, and the result gets returned to the client. This all happens transparently to the developer. And although .NET Remoting has already been deprecated with the release of .NET Framework 3.0 in 2009 and is no longer available on .NET Core and .NET 5+, it is still around, even in contemporary enterprise level software products. Remoting Internals If you are interested in how .NET Remoting works under the hood, here are some insights. In simple terms: when the client connects to the remoting object provided by the server, it creates a RemotingProxy that implements the specified type MyRemotingClass. All method invocations on remote at the client (except for GetType() and GetHashCode()) will get sent to the server as remoting calls. When a method gets invoked on remote, the proxy creates a MethodCall object that holds the information of the method and passed parameters. It is then passed to a chain of sinks that prepare the MethodCall and handle the remoting communication with the server over the given transport. On the server side, the received request is also passed to a chain of sinks that reverses the process, which also includes deserialization of the MethodCall object. It ends in a dispatcher sink, which invokes the actual implementation of the method with the passed parameters. The result of the method invocation is then put in a MethodResponse object and gets returned to the client where the client s | Tool | ||
