Europol has announced the takedown of distributed denial of service (DDoS)-for-hire services that were used to launch thousands of cyber-attacks across the world.
In connection with the operation, Polish authorities have arrested four individuals and the United States has seized nine domains that are associated with the now-defunct platforms.
“The suspects are believed to be behind six separate

Threat actors have been observed actively exploiting security flaws in GeoVision end-of-life (EoL) Internet of Things (IoT) devices to corral them into a Mirai botnet for conducting distributed denial-of-service (DDoS) attacks.
The activity, first observed by the Akamai Security Intelligence and Response Team (SIRT) in early April 2025, involves the exploitation of two operating system command

What happens when cybercriminals no longer need deep skills to breach your defenses? Today’s attackers are armed with powerful tools that do the heavy lifting — from AI-powered phishing kits to large botnets ready to strike. And they’re not just after big corporations. Anyone can be a target when fake identities, hijacked infrastructure, and insider tricks are used to slip past security

Cybersecurity researchers have detailed the activities of an initial access broker (IAB) dubbed ToyMaker that has been observed handing over access to double extortion ransomware gangs like CACTUS.
The IAB has been assessed with medium confidence to be a financially motivated threat actor, scanning for vulnerable systems and deploying a custom malware called LAGTOY (aka HOLERUN).
“LAGTOY can be

At least six organizations in South Korea have been targeted by the prolific North Korea-linked Lazarus Group as part of a campaign dubbed Operation SyncHole.
The activity targeted South Korea’s software, IT, financial, semiconductor manufacturing, and telecommunications industries, according to a report from Kaspersky published today. The earliest evidence of compromise was first detected in

The China-linked threat actor known as Mustang Panda has been attributed to a cyber attack targeting an unspecified organization in Myanmar with previously unreported tooling, highlighting continued effort by the threat actors to increase the sophistication and effectiveness of their malware.
This includes updated versions of a known backdoor called TONESHELL, as well as a new lateral movement

Fortinet has revealed that threat actors have found a way to maintain read-only access to vulnerable FortiGate devices even after the initial access vector used to breach the devices was patched.
The attackers are believed to have leveraged known and now-patched security flaws, including, but not limited to, CVE-2022-42475, CVE-2023-27997, and CVE-2024-21762.
“A threat actor used a known

The cascading supply chain attack that initially targeted Coinbase before becoming more widespread to single out users of the “tj-actions/changed-files” GitHub Action has been traced further back to the theft of a personal access token (PAT) related to SpotBugs.
“The attackers obtained initial access by taking advantage of the GitHub Actions workflow of SpotBugs, a popular open-source tool for

The threat actors behind the zero-day exploitation of a recently-patched security vulnerability in Microsoft Windows have been found to deliver two new backdoors called SilentPrism and DarkWisp.
The activity has been attributed to a suspected Russian hacking group called Water Gamayun, which is also known as EncryptHub and LARVA-208.
“The threat actor deploys payloads primarily by means of

The Chinese threat actor known as FamousSparrow has been linked to a cyber attack targeting a trade group in the United States and a research institute in Mexico to deliver its flagship backdoor SparrowDoor and ShadowPad.
The activity, observed in July 2024, marks the first time the hacking crew has deployed ShadowPad, a malware widely shared by Chinese state-sponsored actors.
