Cybercriminals are shifting from traditional credential theft to session hijacking using infostealer malware, allowing them to bypass multi-factor authentication (MFA). By harvesting and replaying valid session tokens using automated tools, attackers gain rapid, stealthy access to corporate environments, which is then often monetized by Initial Access Brokers.

From Cookies to Keys: Why Hackers Don’t Need Your Passwords Anymore PCPJack | Cloud Worm Evicts TeamPCP and Steals Credentials at Scale SentinelLABS discovered PCPJack, a cloud-focused worm designed to harvest credentials at scale while actively evicting artifacts of a rival threat actor, TeamPCP. The framework targets exposed cloud services like Docker, Kubernetes, and Redis for propagation and lateral movement, notably omitting cryptomining payloads in favor of credential theft and Sliver C2 deployment.
Kimsuky targets organizations with PebbleDash-based tools Kimsuky (APT43) has updated its arsenal with new PebbleDash and AppleSeed malware variants, including the Rust-based HelloDoor and httpMalice backdoors. The group is increasingly utilizing legitimate services like VSCode Remote Tunnels, Cloudflare Quick Tunnels, and DWAgent for covert C2 and post-exploitation access, primarily targeting South Korean entities and global defense sectors.
FrostyNeighbor: Fresh mischief and digital shenanigans FrostyNeighbor, a Belarus-aligned threat actor, has updated its toolset to target Ukrainian governmental organizations with a multi-stage compromise chain. The attack utilizes spearphishing with malicious PDFs that redirect to a RAR archive containing a JavaScript dropper, which ultimately deploys a Cobalt Strike beacon via the PicassoLoader malware following strict server-side and manual victim validation.
GopherWhisper: A burrow full of malware ESET researchers uncovered GopherWhisper, a previously undocumented China-aligned APT group targeting a Mongolian governmental entity. The group utilizes a diverse arsenal of custom, primarily Go-based malware that leverages legitimate services like Slack, Discord, and Microsoft Outlook for command and control, blending malicious traffic with normal enterprise communications.
Feross on TBPN: How North Korea Hijacked Axios North Korean state actors compromised the lead maintainer of the popular Axios npm package through a highly targeted social engineering campaign. By establishing credibility via fake corporate personas and communication channels, the attackers tricked the developer into executing malware disguised as a software update, ultimately gaining unauthorized publish access to the npm registry.
Attackers Are Impersonating a Linux Foundation Leader in Slack to Target Open Source Developers A high-severity social engineering campaign is actively targeting open source developers on Slack by impersonating Linux Foundation leaders. The multi-stage attack uses a fake AI tool lure to harvest credentials and trick victims into installing a malicious root certificate, leading to traffic interception and malware execution on macOS and Windows systems.
Attackers Are Hunting High-Impact Node.js Maintainers in a Coordinated Social Engineering Campaign A sophisticated social engineering campaign linked to DPRK-nexus actor UNC1069 is targeting high-impact Node.js and npm maintainers. Attackers build rapport over weeks before luring victims to spoofed video conferencing sites that deploy infostealing malware designed to hijack session tokens, bypass 2FA, and compromise the open-source software supply chain.
Axios Maintainer Confirms Social Engineering Attack Behind npm Compromise The lead maintainer of the widely used Axios npm package fell victim to a sophisticated social engineering attack. Attackers tricked the maintainer into installing a Remote Access Trojan (RAT) during a fake MS Teams meeting, enabling session hijacking that bypassed 2FA and allowed the unauthorized publication of malicious Axios versions to the npm registry.
