A new version of the DreamBus botnet malware is leveraging a critical vulnerability in RocketMQ servers to infect devices. The vulnerability, tracked as CVE-2023-33246, is a permission verification issue in RocketMQ version 5.1.0 and older. DreamBus attacks targeting the vulnerability were first observed in early June, with a spike in activity in mid-June. Attackers use the 'interactsh' reconnaissance tool to identify vulnerable servers and download a malicious bash script named 'reketed' to install the DreamBus main module. DreamBus remains active on infected systems by setting up a system service and a cron job, with lateral spreading mechanisms and a scanner module for discovering vulnerabilities. The primary goal of the DreamBus campaign appears to be Monero mining, but the modular nature of the malware enables future expansion of capabilities. Administrators are advised to upgrade to RocketMQ version 5.1.1 or later to mitigate the risk of DreamBus attacks. Good patch management across all software products is recommended to combat this malware and similar threats.

The FBI carried out a law enforcement operation called Operation Duck Hunt to disrupt the Qakbot botnet. The operation seized the botnet's infrastructure and uninstalled the Qakbot malware from infected devices. Qakbot, also known as Qbot and Pinkslipbot, is a banking trojan that evolved into a malware delivery service used for ransomware attacks and data theft. The malware is distributed through phishing campaigns, reply-chain email attacks, and exploits zero-day vulnerabilities in Windows. Qakbot operators partnered with ransomware gangs to gain initial access to networks. The FBI dismantled the botnet by seizing the attacker's servers and creating a removal tool to uninstall the malware. The FBI accessed encryption keys used by Qakbot for communication and replaced the malware with an FBI-controlled module. A custom DLL file issued by the FBI acted as a removal tool and stopped the Qakbot process on infected devices. The FBI expects further devices to be cleaned as they connect back to the hijacked Qakbot infrastructure.

Chinese APT hacking group, GREF, uploaded trojanized Signal and Telegram apps containing the BadBazaar spyware onto Google Play and Samsung Galaxy Store BadBazaar spyware was previously used to target ethnic minorities in China but is now targeting users in Ukraine, Poland, the Netherlands, Spain, Portugal, Germany, Hong Kong, and the United States BadBazaar spyware can track device location, steal call logs and SMS, record phone calls, take pictures, exfiltrate contact lists, and steal files or databases GREF used trojanized versions of the apps named "Signal Plus Messenger" and "FlyGram," with dedicated websites to add legitimacy to the campaign FlyGram targets sensitive data such as contact lists, call logs, Google Accounts, and WiFi data, while Signal Plus Messenger focuses on extracting Signal-specific information and allows attackers to link to victims' Signal accounts without their knowledge At least 13,953 FlyGram users enabled a backup feature that sent communication data to an attacker-controlled server Android users are advised to use the original versions of Signal and Telegram and avoid downloading fork apps promising enhanced privacy or additional features from official app stores.

Hackers are targeting Cisco Adaptive Security Appliance (ASA) SSL VPNs in credential stuffing and brute-force attacks. Rapid7 security researchers confirm that attackers have been attempting to guess login credentials since March of this year. No instances have been found where the attackers bypassed multi-factor authentication (MFA). At least 11 customers have been breached in Cisco ASA-related attacks between March and August. Most attacks utilized similar infrastructure and common usernames. Attackers remotely accessed networks and compromised systems using stolen domain credentials. Some breaches led to LockBit and Akira ransomware attacks. Admins and security teams are advised to deactivate default accounts and passwords and enforce MFA for all VPN users.

VMware Aria Operations for Networks is vulnerable to a critical severity authentication bypass flaw. The flaw allows remote attackers to bypass SSH authentication and access private endpoints. Exploiting the flaw could lead to data exfiltration or manipulation through the product's command line interface. Upgrading to version 6.11 or applying the KB94152 patch is the only way to remediate the critical flaw, as no workarounds or mitigation recommendations have been provided. Another high-severity flaw, CVE-2023-20890, also addressed by the patch, allows for arbitrary file write and remote code execution. Due to the value of assets held by large organizations using this software, hackers are quick to exploit critical severity flaws. Active exploitation of previous vulnerabilities in Aria Operations for Networks has already been reported, emphasizing the need for prompt patching or upgrading. Delaying patching or upgrading would significantly increase the risk of hacker attacks on the network.

Popular WordPress data migration plugin, All-in-One WP Migration, has a flaw that could lead to data breaches The flaw allows unauthenticated access token manipulation, giving attackers access to sensitive site information Various premium extensions of the plugin contain the same vulnerable code Attackers could divert website migration data or restore malicious backups The primary ramification is a potential data breach, including user details and proprietary information The issue was discovered by PatchStack's researcher and reported to ServMask, the plugin's vendor ServMask released security updates to fix the flaw Users of the impacted extensions are advised to upgrade to the fixed versions and use the latest version of the base plugin.

Apple is accepting applications from iOS security researchers to receive a Security Research Device (SRD) iPhone 14 Pro. SRDs are specially-built devices with disabled security features and shell access for vulnerability research on the iOS platform. Researchers can use the SRD to discover vulnerabilities and have them considered for Apple's Security Bounty program. The SRDs are 12-month renewable loans and should only be used by authorized individuals and remain within the premises of the security research facility. Universities can also request access to the SRDs for instructional purposes. Applications for the 2024 iPhone Security Research Device Program are open until October 31. Accepted participants will be notified at the beginning of 2024.

Toyota Japan experienced a production system malfunction that halted production across 14 plants for 36 hours. The automaker states that the malfunction was not caused by a cyber attack, but the cause is still under investigation. Production resumed as planned on Wednesday. Toyota has previously faced data leaks and other issues, but the incident is not expected to impact production volumes. The company has some slack in its systems that can make up for the missed days of production. This incident is not as severe as previous problems such as recalls due to wheels falling off cars.
