Google Just Patched These Two Chrome Zero-day Bugs That Are Under Attack Right Now
(published: October 1, 2021)
Google has warned users of Google Chrome to update to version 94.0.4606.71, due to two new zero-days that are currently being exploited in the wild. This marks the second update in a month due to actively exploited zero-day flaws. The first of these common vulnerabilities and exposures (CVEs), CVE-2021-37975, is a high severity flaw in the V8 JavaScript engine, which has been notoriously difficult to protect and could allow attackers to create malware that is resistant to hardware mitigations.
Analyst Comment: Users and organizations are recommended to regularly check for and apply updates to the software applications they use, especially web browsers that are increasingly used for a variety of tasks. Organizations can leverage the capabilities of Anomali Threatstream to rapidly get information about new CVEs that need to be mitigated through their vulnerability management program.

Hydra Malware Targets Customers of Germany's Second Largest Bank
(published: October 1, 2021)
A new campaign leveraging the Hydra banking trojan has been discovered by researchers. The malware containing an Android application impersonates the legitimate application for Germany's largest bank, Commerzbank. While Hydra has been seen for a number of years, this new campaign incorporates many new features, including abuse of the android accessibility features and permissions which give the application the ability to stay running and hidden with basically full administrator privileges over a victim's phone. It appears to be initially spread via a website that imitates the official Commerzbank website. Once installed it can spread via bulk SMS messages to a user's contacts.
Analyst Comment: Applications, particularly banking applications, should only be installed from trusted and verified sources and reviewed for suspicious permissions they request. Similarly, emails and websites should be verified before using.

New Sophisticated Email-based Attack From NOBELIUM
(published: May 28, 2021)
NOBELIUM, the threat actor behind SolarWinds attacks, has been conducting a widespread email campaign against more than 150 organizations. Using attached HTML files containing JavaScript, the email will write an ISO file to disk; this contains a Cobalt Strike beacon that will activate on completion. Once detonated, the attackers have persistent access to a victims’ system for additional objectives such as data harvesting/exfiltration, monitoring, and lateral movement.
Analyst Comment: Be sure to update and monitor email filter rules constantly. As noted in the report, many organizations managed to block these malicious emails; however, some payloads successfully bypassed cloud security due to incorrect/poorly implemented filter rules.

Evolution of JSWorm Ransomware
(published: May 25, 2021)
JSWorm ransomware was discovered in 2019, and since then different variants have gained notoriety under different names such as Nemty, Nefilim, and Offwhite, among others. It has been used to target multiple industries with the largest concentration in engineering, and others including finance, healthcare, and energy. While the underlying code has been rewritten from C++ to Golang (and back again), along with revolving distribution methods, JSWorm remains a consistent threat.
Analyst Comment: Ransomware threats often affect organisations in two ways. First encrypting operational critical documents and data. In these cases EDR solutions will help to block potential Ransomwares and data backup solutions will help for restoring files in case an attack is successful. Secondly, sensitive customer and business files are exfiltrated and leaked online by ransomware gangs. DLP solutions will help to identify and block potential data exfiltration attempts. Whereas network segregation and encryption of critical data will play an important role in reducing the risk.

2020-12-29 21:22:00 | Actionable Threat Intelligence Available for Sunburst Cyber Attacks on SolarWinds (lien direct) | On Dec. 13, FireEye published a detailed analysis about the attack carried out against SolarWinds, which appears to have compromised its Orion IT monitoring and management platform to spread the Sunburst Backdoor malware. As part of the attack, which started in March, the Orion platform started sending out the digitally-signed trojanized malware via regular updates. According to SolarWinds, the compromised update may have been installed by fewer than 18,000 of its customers, including many U.S. federal agencies and Fortune 500 firms that use Orion to monitor the health of their IT networks. In a related blog post, FireEye also announced that a highly sophisticated state-sponsored adversary penetrated its network and stole FireEye Red Team tools used to test customers’ security. In response to the attacks, Anomali has collected, curated, and distributed clear and concise open-source intelligence (OSINT) to help organizations determine if they have been impacted. Two key resources released include a SolarWinds Breach Threat Bulletin and a FireEye Red Team Tools Breach Threat Bulletin. These continually updated resources, for use inside Anomali ThreatStream, include threat analysis, signature threat models, and over 2,000 operationalized indicators of compromise (IOCs) for automated distribution to security controls. Both are available now to Anomali’s 1,500 customers. What Can I Do with This Threat Intelligence?...and How to Do It Our intent in aggregating and curating this threat intelligence is to provide organizations with high-fidelity IOCs that can immediately be pushed into their security stacks for rapid, proactive blocking and alerting. Security products that can take advantage of this actionable threat intelligence include security information and event management (SIEM), endpoint detection and response platforms, firewalls, domain name system (DNS) servers, security orchestration, automation, and response (SOAR) platforms, and other operational security products. These Anomali threat bulletins are designed to be used in conjunction with Anomali ThreatStream, a threat intelligence platform that allows organizations to aggregate, curate, analyze, and distribute multiple sources of threat intelligence to their operational security systems. Inside of the SolarWinds Breach Threat Bulletin, all of these IOCs have been tagged with “solarwinds”, “sunburst backdoor”, “unc2452”, or “avsvmcloud.com.” This enables ThreatStream users to create a simple rule to automatically push IOCs to their security systems, enabling real-time defense against both attacks. For example, if a compromised server inside the organization attempts to connect to a command and control (C2) server outside of the organization, Anomali customers that have activated this research will automatically block the C2 URL, avoiding risk of further compromise and data exfiltration. How Can I Get This Intelligence? The Anomali SolarWinds and FireEye Threat Bulletins are automatically available to Anomali’s ThreatStream customers, and all organizations participating in Anomali-powered threat intelligence sharing communities (ISACs).

2020-12-29 20:12:00 | Anomali ThreatStream Sunburst Backdoor Custom Dashboard Provides Machine Readable IOCs Related To SolarWinds Supply Chain Attack (lien direct) | SolarWinds, a provider of IT management and monitoring software deployed by thousands of global customers, was breached between March and June of 2020 by an Advanced Persistent Threat (APT) that cybersecurity company FireEye is tracking as UNC2452. As part of the supply chain attack, the APT compromised the company’s Orion business software with trojanized malware known as Sunburst, which opens a backdoor into the networks of customers who executed Orion updates.
Immediately following news of the attack, Anomali Threat Research launched a custom threat intelligence dashboard called Sunburst Backdoor. Now available to Anomali ThreatStream customers, the dashboard is accessible via the user console. It is preconfigured to provide immediate access and visibility into all known Sunburst Backdoor indicators of compromise (IOCs) that are made available through commercial and open-source threat feeds that users manage on ThreatStream.
Customers using ThreatStream, Anomali Match, and Anomali Lens can immediately detect any IOCs present in their environments, quickly consume threat bulletins containing machine readable IOCs to operationalize threat intelligence across their security infrastructures, and communicate to all stakeholders how they have been impacted.
As part of ongoing product enhancements that further automate and speed essential tasks performed by threat intelligence and security operations analysts, Anomali recently added thematic dashboards that respond to significant global events. In addition to Sunburst Backdoor, ThreatStream customers currently have access to additional dashboards announced as part of our December quarterly product release.
Customers can integrate Sunburst Backdoor and other dashboards via the “+ Add Dashboard” tab in the ThreatStream console:
After integration, users will have immediate access to the Sunburst Backdoor dashboard, which continually updates IOCs as they become available:
Organizations interested in learning more about Anomali ThreatStream and our custom dashboard capabilities can request a demo here.
For organizations interested in gaining wider visibility and detection capabilities for the Sunburst cyberattack, Anomali Threat Research has compiled and curated an initial threat bulletin and downloadable set of OSINT IOCs available here. |
