“The MOIS group used the authentic still compromised Israeli site for command-and-manage (C2), demonstrating an improvement in operational security, as the method complicates defenders’ attempts, which frequently leverage geolocation knowledge to determine anomalous network activity,” Microsoft famous, even more pointing out Storm-0133’s reliance on the Mango malware in these intrusions.

ESET also claimed an unnamed Indian info management solutions provider was at the getting close of an attack mounted by the North Korea-backed Lazarus Group in January 2023 working with an Accenture-themed social engineering entice.

“The aim of the attackers was to monetize their presence in the company’s network, most possible by small business email compromise,” the firm said, calling it a change from its regular victimology designs.

The Lazarus Group, in February 2023, is also claimed to have breached a defense contractor in Poland via pretend occupation offers to initiate an attack chain that weaponizes a modified version of SumatraPDF to deploy a RAT named ScoringMathTea and a innovative downloaded codenamed ImprudentCook.

Rounding off the listing is a spear-phishing exercise from Russia-aligned APT teams this kind of as Gamaredon, Sandworm, Sednit, The Dukes, and SaintBear, the very last of which has been detected utilizing an updated model of its Elephant malware framework and a novel Go-primarily based backdoor recognized as ElephantLauncher.

“The malware is modular and makes use of the Lua scripting language in conjunction with its Just-in-Time (JIT) compiler to execute malicious code that is tough to detect,” Kaspersky researchers reported.

“It also capabilities various anti-debugging capabilities and employs Windows APIs by means of Lua FFI, which makes use of C language bindings to have out its actions.”
