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 APT ChamelGang Targets Russian Energy, Aviation Orgs
(published: October 1, 2021)
A new Advanced Persistent Threat (APT) group dubbed “ChamelGang” has been identified to be targeting the fuel and energy complex and aviation industry in Russia, exploiting known vulnerabilities like Microsoft Exchange Server’s ProxyShell and leveraging both new and existing malware to compromise networks. Researchers at Positive Technologies have been tracking the group since March 2017, and have observed that they have attacked targets in 10 countries so far. The group has been able to hi |

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.
