In February 2023, ESET researchers detected a spearphishing campaign targeting a governmental entity in Guyana. While we haven’t been able to link the campaign, which we named Operation Jacana, to any specific APT group, we believe with medium confidence that a China-aligned threat group is behind this incident. In the attack, the operators used a […]
Security researchers have discovered a major new scam operation designed to trick job seekers into parting with cryptocurrency, by getting them to complete meaningless tasks they believe will earn them money. Dubbed “WebWyrm” by CloudSEK, the operation has already targeted more than 100,000 individuals across over 50 countries by impersonating over 1000 companies across 10 […]
ReversingLabs researchers have identified a new, malicious supply chain attack affecting the npm platform. The “typosquatting” campaign first appeared in August and pushed a malicious package, node-hide-console-windows, which downloaded a Discord bot that facilitated the planting of an open source rootkit, r77. This is the first time ReversingLabs researchers have discovered a malicious open source […]
Oct 03, 2023THNArtificial Intelligence / Cyber Threat Cybersecurity researchers have disclosed multiple critical security flaws in the TorchServe tool for serving and scaling PyTorch models that could be chained to achieve remote code execution on affected systems. Israel-based runtime application security company Oligo, which made the discovery, has coined the vulnerabilities ShellTorch. “These vulnerabilities […] […]
A group of academic researchers has devised a technique to extract sounds from still images captured using smartphone cameras with rolling shutter and movable lens structures. The movement of camera hardware, such as the Complementary Metal-oxide–Semiconductor (CMOS) rolling shutters and the moving lenses used for Optical Image Stabilization (OIS) and Auto Focus (AF), create sounds […]
ESET researchers have uncovered a Lazarus attack against an aerospace company in Spain, where the group deployed several tools, most notably a publicly undocumented backdoor we named LightlessCan. Lazarus operators obtained initial access to the company’s network last year after a successful spearphishing campaign, masquerading as a recruiter for Meta – the company behind Facebook, […]
The researcher’s role in investigating the scam led to a grand jury subpoena, highlighting the potential legal risks faced by ethical hackers and defenders involved in similar work.
Researchers who discovered two critical vulnerabilities in Microsoft SharePoint Server have released details of an exploit they developed that chains the two vulnerabilities together to enable remote code execution on affected servers. Separately, another security researcher this week posted proof-of-concept code on GitHub for one of the SharePoint vulnerabilities that shows how an attacker could […]
Researchers have discovered the infrastructure linked to a threat group called ShadowSyndicate, believed to have launched attacks using seven distinct ransomware families in the last year. Active since June 2022 or earlier, connections between this group and the developers of Cl0p, Play, Royal, and Cactus ransomware have been highlighted in a study by Group-IB and […]
