In May 2026, a cyber-espionage campaign by the Armored Likho group (also known as Eagle Werewolf) targeted private individuals and organizations across Russia, including major corporations, public sector entities, IT companies, and educational institutions. The attackers employed fake donation service applications as initial infection vectors. The campaign introduced the Still Toolkit, comprising two Rust-based components: Still Sync, which steals Telegram session data and leverages the Telegram API to extract chat logs and media files, and Still Audio, an implant that conducts covert audio surveillance by detecting speech patterns and recording conversations. The toolkit demonstrates sophisticated capabilities including Dead Drop Resolver techniques, RMS-based voice activity detection, and gRPC-based C2 communications. The campaign shows significant code overlap with previous Armored Likho operations, particularly from February 2026, including identical dropper architecture, encryption algorithms, and inf...

An Akira ransomware affiliate gained initial access through an exposed SonicWall VPN without multi-factor authentication via credential spraying. After compromising the domain controller, the attacker performed Active Directory enumeration, collected and exfiltrated data using WinRAR and s5cmd to cloud storage. The affiliate employed a novel evasion technique by rebooting the victim host into Safe Mode with Networking to disable EDR and antivirus protection. AnyDesk was installed as a persistent remote access mechanism. However, the Safe Mode environment caused the ransomware to fail due to out-of-virtual-memory errors, preventing encryption. Despite the encryption failure, the attacker had already exfiltrated credentials and file shares, enabling extortion through data leak threats. This marks the first observed instance of Akira affiliates using Safe Mode boot as an anti-EDR technique.

A campaign uses fake websites impersonating CNN, Stremio, and Avast to distribute legitimate remote administration software O&O Syspectr pre-linked to attacker accounts. The lookalike sites closely mimic authentic homepages and trick Windows users into downloading installers that appear legitimate but grant attackers remote access to victim computers. Additional fake sites use cryptocurrency mining game lures to distribute the same tool. All installers are digitally signed legitimate software, making antivirus detection difficult. The campaign uses multiple Syspectr account IDs embedded in filenames, with CNN, Avast, and Stremio lures sharing one account while crypto-mining lures use another. O&O Software responded by disabling Remote Desktop and Remote Console access for free accounts and suspending the abusive accounts.

The Head Mare APT group exploited a chain of vulnerabilities in TrueConf video conferencing servers to deploy PhantomCore and PhantomGraph backdoors. Attackers connected to unpatched TrueConf servers via port 4307/TCP without authorization, using vulnerabilities KLCERT-26-057 and KLCERT-26-058 to execute arbitrary code with NT AUTHORITY\SYSTEM privileges. They replaced legitimate TrueConf client installers with infected versions containing PhantomCore, and deployed a web shell for persistent access. The PhantomGraph backdoor utilized Microsoft OneDrive as command-and-control infrastructure. Affected TrueConf versions included 5.3.X through 5.3.9, 5.4.X through 5.4.9, and 5.5.X through 5.5.5. Multiple Russian organizations across various industries were targeted, including instrument manufacturing, electronics, transportation, energy, IT, and software development. The vulnerabilities were patched in June 2026.

A large-scale software supply chain attack compromised over 400 npm packages through a self-propagating worm called ChainDrop, a new variant of Mini Shai-Hulud. The campaign exploits stolen npm publishing credentials to automatically modify and republish legitimate software releases. ChainDrop targets developer workstations and CI/CD environments, harvesting credentials from npm, GitHub, AWS, Kubernetes, and HashiCorp Vault before validating access and enumerating resources. The malware uses preinstall lifecycle scripts for automatic execution, establishes persistence through repository configuration modifications, and abuses GitHub Actions OIDC trusted publishing workflows. After stealing credentials, it autonomously propagates by downloading packages, inserting malicious payloads, and republishing them with incremented versions, demonstrating how compromised developer identities can enable widespread ecosystem compromise.

Cybercriminals are exploiting API keys used by developers to access AI platforms through a technique called token jacking. Attackers steal these authentication tokens to gain unauthorized access to expensive AI resources, which they either use themselves or resell through gray-market services called transfer stations. These transfer stations act as intermediaries, offering frontier AI model access at discounted rates using stolen credentials. The financial impact can be catastrophic, with victims potentially losing hundreds of thousands to millions of dollars before detection due to unlimited scaling defaults and cyclical billing. Attackers obtain tokens through information stealers, phishing campaigns, compromised code repositories, and poisoned npm packages. Organizations can mitigate risks through spending limits, privileged account reviews, short-term bearer tokens, AI gateways, and tight development environment management.

A sophisticated scam is spreading through WhatsApp that exploits the platform's legitimate 'Linked devices' feature to take over user accounts. Attackers compromise existing accounts and send messages to contacts asking them to vote for a friend or relative in various online contests. When victims click the provided link, they are redirected through pages appearing to be WhatsApp-related, often using the legitimate wa.me domain. The attack tricks users into authorizing a new linked session, granting attackers full access to read messages, send messages as the victim, and access contacts. The scam is particularly effective because it comes from known contacts and relies on trust and quick reactions. Once compromised, attackers can continue the scam by messaging the victim's contacts, creating a chain of account takeovers without triggering traditional security alerts.

An authentication bypass vulnerability, CVE-2026-18577, affecting N-able N-central Remote Monitoring and Management platform has been actively exploited since August 1, 2026. This vulnerability emerged after an incomplete fix for a previous authentication bypass issue CVE-2026-18556. The flaw allows remote unauthenticated attackers to bypass authentication mechanisms and gain administrative control over vulnerable N-central servers. Attackers have exploited this vulnerability to leverage the platform's Take Control functionality for remote access to managed endpoints and deployed Cloudflare Tunnel (cloudflared) to establish persistent remote access. Given that N-central is widely used by managed service providers and enterprise IT teams with extensive administrative privileges, successful compromise provides attackers an efficient pathway to compromise downstream managed systems. CISA added this vulnerability to its Known Exploited Vulnerability catalog on August 3, 2026.

GenieLocker is a new ransomware family active since March 2026, targeting organizations in the Russian Federation, primarily in manufacturing. Attributed to the financially motivated Toy Ghouls group (also known as Bearlyfy, Labubu, and Laboo.boo), this custom-designed ransomware marks a shift from their previous reliance on third-party encryption tools like RedAlert, LockBit, and Babuk. GenieLocker exists in two variants: PE builds for Windows and ELF builds for Linux and ESXi. The Windows version features sophisticated capabilities including process termination, service shutdown, anti-debugging techniques, and advanced encryption using the libsodium library with XChaCha20-Poly1305 algorithm. Initial access typically occurs through compromised VPN credentials from trusted partners, followed by deployment of tools like Mimikatz, SoftPerfect Network Scanner, and SSH utilities for lateral movement before deploying ransomware using PsExec and PAExec.

In May 2026, a sophisticated Monero cryptomining campaign was identified targeting Linux environments. Attackers gained initial access through trusted third-party relationships, then escalated to root privileges. Rather than operating openly as root, they weaponized Linux Pluggable Authentication Modules (PAM) to impersonate multiple low-privileged users, creating a forensic smokescreen and establishing redundant persistence through cronjobs. The operators suppressed system logging and deployed a customized XMRig 6.25.0 implant that self-unlinks after execution, running entirely in memory. The binary uses XOR encryption for configuration obfuscation and employs process masquerading to blend with legitimate processes. Campaign tracking revealed operations linked to the V25 Generation 26 family, connecting to the domain unable.download for mining pool communication.
