The Hacker News published A New findings show that malicious actors could leverage a sneaky malware detection evasion technique and bypass endpoint security solutions by manipulating the Windows Container Isolation Framework.

The findings were presented by Deep Instinct security researcher Daniel Avinoam at the DEF CON security conference held earlier this month.

Microsoft's container architecture (and by extension, Windows Sandbox) uses what's called a dynamically generated image to separate the file system from each container to the host and at the same time avoid duplication of system files.

It's nothing but an "operating system image that has clean copies of files that can change, but links to files that cannot change that are in the Windows image that already exists on the host," thereby bringing down the overall size for a full OS. Read More..

August 31, 2023 BleepingComputer published Trojanized Signal and Telegram apps containing the BadBazaar spyware were uploaded onto Google Play and Samsung Galaxy Store by a Chinese APT hacking group known as GREF.

This malware was previously used to target ethnic minorities in China, but ESET's telemetry shows that this time, the attackers target users in Ukraine, Poland, the Netherlands, Spain, Portugal, Germany, Hong Kong, and the United States.

BadBazaar's capabilities include tracking the device's precise location, stealing call logs and SMS, recording phone calls, taking pictures using the camera, exfiltrating contact lists, and stealing files or databases. Read More..

August 31, 2023 The Hacker News published A hacking outfit nicknamed Earth Estries has been attributed to a new, ongoing cyber espionage campaign targeting government and technology industries based in the Philippines, Taiwan, Malaysia, South Africa, Germany, and the U.S.

"The threat actors behind Earth Estries are working with high-level resources and functioning with sophisticated skills and experience in cyber espionage and illicit activities," Trend Micro researchers Ted Lee, Lenart Bermejo, Hara Hiroaki, Leon M Chang, and Gilbert Sison said.

Active since at least 2020, Earth Estries is said to share tactical overlaps with another nation-state group tracked as FamousSparrow, which was first exposed by ESET in 2021 as exploiting ProxyLogon flaws in Microsoft Exchange Server to penetrate hospitality, government, engineering, and legal sectors. Read More..

August 30, 2023 BleepingComputer published Hackers are targeting Cisco Adaptive Security Appliance (ASA) SSL VPNs in credential stuffing and brute-force attacks that take advantage of lapses in security defenses, such as not enforcing multi-factor authentication (MFA).

Last week, BleepingComputer reported that the Akira ransomware gang was breaching Cisco VPNs for initial network access.

Rapid7 security researchers have provided additional insights regarding these incidents in a report published on Tuesday, revealing that attackers have been directing their efforts towards these devices since March of this year in brute force attacks designed to guess the targets' login credentials.” Read More..
