A new piece of research has detailed the increasingly sophisticated nature of the malware toolset employed by an advanced persistent threat group named Earth Aughisky. "Over the last decade, the group has continued to make adjustments in the tools and malware deployments on specific targets located in Taiwan and, more recently, Japan," Trend Micro disclosed in a technical profile last week.

A threat actor tracked under the moniker Webworm has been linked to bespoke Windows-based remote access trojans, some of which are said to be in pre-deployment or testing phases. "The group has developed customized versions of three older remote access trojans, including Trochilus RAT, Gh0st RAT, and 9002 RAT," the Symantec Threat Hunter team, part of Broadcom Software, said in a report shared with The Hacker News.

Lazarus, also known as Hidden Cobra or Zinc, is a known nation-state cyberespionage threat actor originating from North Korea, according to the U.S. government. Lazarus could use only VSingle, VSingle and MagicRAT, or a new malware dubbed YamaBot.

"A notable feature of these attacks is that the attackers leveraged a wide range of legitimate software packages in order to load their malware payloads using a technique known as DLL side-loading," the Symantec Threat Hunter team, part of Broadcom Software, said in a report shared with The Hacker News. The attacks entail the use of old and outdated versions of security solutions, graphics software, and web browsers that are bound to lack mitigations for DLL side-loading, using them as a conduit to load arbitrary shellcode designed to execute additional payloads.

A newly discovered cyber-espionage group has been hacking governments and high-profile companies in Asia since at least 2020 using a combination of custom and existing malicious tools. The threat group, tracked as Worok by ESET security researchers who first spotted it, has also attacked targets from Africa and the Middle East.

A months-long cyber espionage campaign undertaken by a Chinese nation-state group targeted several entities with reconnaissance malware so as to glean information about its victims and meet its strategic goals. "The targets of this recent campaign spanned Australia, Malaysia, and Europe, as well as entities that operate in the South China Sea," enterprise security firm Proofpoint said in a published in partnership with PwC. Targets encompass local and federal Australian Governmental agencies, Australian news media companies, and global heavy industry manufacturers which conduct maintenance of fleets of wind turbines in the South China Sea.

Google's Threat Analysis Group recently discovered a new tool named Hyperscrape which is able to steal data from mailboxes such as Gmail, Yahoo! or Microsoft Outlook. Hyperscrape is a tool written for Windows systems in.

Facebook parent company Meta disclosed that it took action against two espionage operations in South Asia that leveraged its social media platforms to distribute malware to potential targets. The first set of activities is what the company described as "Persistent and well-resourced" and undertaken by a hacking group tracked under the moniker Bitter APT targeting individuals in New Zealand, India, Pakistan and the U.K. "Bitter used various malicious tactics to target people online with social engineering and infect their devices with malware," Meta said in its Quarterly Adversarial Threat Report.

Media organizations and journalists in the last years have been increasingly targeted by state-sponsored advanced persistent threat actors with a clear purpose: Obtain access to their sensitive information, spy their activities or even identify their sources. Zirconium, a threat actor also known as TA412, has been targeting American journalists since 2021.

A China-based advanced persistent threat group is possibly deploying short-lived ransomware families as a decoy to cover up the true operational and tactical objectives behind its campaigns. The activity cluster, attributed to a hacking group dubbed Bronze Starlight by Secureworks, involves the deployment of post-intrusion ransomware such as LockFile, Atom Silo, Rook, Night Sky, Pandora, and LockBit 2.0.
