Researchers at Jamf Threat Labs detail CrashStealer, which steals passwords, cryptocurrency wallets and more

A China-linked threat cluster has been exploiting vulnerable Roundcube servers at U.S. and Canadian universities to steal credentials and deploy backdoor malware. [...]

Attackers are hiding a data-stealing trojan inside fake exploit code aimed at the people who hunt bugs for a living. The malware, called ChocoPoC, travels in Python proof-of-concept (PoC) repositories on GitHub that claim to exploit hot new CVEs

RustDuck is a small, evolving DDoS botnet migrating to Rust. It uses advanced encryption, anti-analysis evasion, and exploits known IoT flaws. Since February 2026, researchers at QiAnXin’s XLab have been tracking a new malware family, called RustDuck, that hijacks routers, cameras, Android set-top boxes, and exposed servers, then uses them to flood targets with junk […]

Gamaredon exploits a WinRAR flaw to drop modular, nearly fileless malware on Ukrainian targets, hiding payloads in Windows streams and resolving C2s via Telegram. Sekoia’s Threat Detection & Research team dropped a YARA rule in late December 2025 to hunt for new initial access vectors, and by January 2026 it had already generated a dozen […]

Cybersecurity researchers have exposed a new Mirai-derived botnet that self-identifies as xlabs_v1 and targets internet-exposed devices running Android Debug Bridge (ADB) to enlist them in a network capable of carrying out distributed denial-of-service (DDoS) attacks

Darksword is the second iOS exploit chain in a month A new exploit kit targeting iPhone users and stealing their sensitive data is being abused by "multiple" spyware vendors and suspected nation-state goons, security researchers said on Wednesday.…

LLM-Built Toolkit Hit 91 Hosts, Mined Funds in MoneroSecurity researchers detected artificial intelligence-generated malware exploiting the React2Shell vulnerability, allowing attackers with no coding expertise to build functional exploits. The attacker may have circumvented an AI model's safeguards by framing the malicious coding request as homework.

Cybersecurity researchers have uncovered a new phishing campaign that exploits social media private messages to propagate malicious payloads, likely with the intent to deploy a remote access trojan (RAT)

BitSight research has revealed how threat actors exploit calendar subscriptions to deliver phishing links, malware and social engineering attacks through hijacked domains

Researchers at BlackFrog have uncovered Matrix Push C2, a malicious command-and-control system that abuses web browser push notifications to deliver malware

Cybersecurity researchers have discovered a new vulnerability in OpenAI's ChatGPT Atlas web browser that could allow malicious actors to inject nefarious instructions into the artificial intelligence (AI)-powered assistant's memory and run arbitrary code

Malware campaigns distributing the RondoDox botnet have expanded their targeting focus to exploit more than 50 vulnerabilities across over 30 vendors

Researchers Uncover Covert Chinese Access to US Service Provider InfrastructureMandiant said it has tracked a Chinese-linked espionage campaign using BRICKSTORM malware to quietly embed within U.S. infrastructure and service providers for over a year, exploiting appliance-level blind spots to maintain persistence, evade detection and potentially develop zero-day exploits.

Cybersecurity researchers have disclosed details of a new botnet that customers can rent access to conduct distributed denial-of-service (DDoS) attacks against targets of interest

MuddyWater Also Embraces Bulletproof Hosts and Custom MalwareThe Iranian nation-state cyberespionage group MuddyWater is going back to the future with attacks featuring Microsoft Office documents with malicious macros. It is also shifting to homegrown malware in place of commercial remote monitoring and management tools, said researchers.

Cybersecurity researchers have discovered a new ransomware strain dubbed HybridPetya that resembles the notorious Petya/NotPetya malware, while also incorporating the ability to bypass the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems using a now-patched vulnerability disclosed earlier this year

Defrauding search with custom malware, Potato-family exploits A new China-aligned cybercrime crew named GhostRedirector has compromised at least 65 Windows servers worldwide - spotted in a June internet scan - using previously undocumented malware to juice gambling sites' rankings in Google search, according to ESET researchers.…

Cybersecurity researchers have flagged a new technique that cybercriminals have adopted to bypass social media platform X's malvertising protections and propagate malicious links using its artificial intelligence (AI) assistant Grok
