The China-aligned espionage group Mustang Panda is running two campaigns against the Indian government and hydropower targets, deploying new malware and turning a legitimate cloud service into its command channel.
Acronis Threat Research Unit found active compromises inside Indian government networks, including machines used by senior administrative staff, and worked with
This week was a reminder that attackers do not always need big tricks. One small mistake, one old access path, one missed patch, and suddenly the door is open.
The noise is not all noise, either. Forums are talking, researchers are finding easy cracks, and defenders have more cleanup waiting.
Here’s the full Monday recap.
⚡ Threat of the Week
New DirtyClone Linux Kernel Flaw Lets Local
New findings unearthed by Infoblox show that more than 236,000 websites are using investment scam templates built using a legitimate Chinese open-source, cross-platform application development framework called DCloud Uni-App.
The templates power bogus cryptocurrency exchanges, multi-language pig-butchering operations, WhatsApp phishing networks, fake gambling platforms, brand-impersonation
Today’s encrypted data, such as credentials, may no longer remain confidential in the future because the public-key cryptography protecting it will soon be broken by quantum computers. Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by
A Russian advanced persistent threat (APT) group has continued to evolve and expand its malware arsenal as part of its ongoing cyber onslaught against Ukraine throughout 2025.

Microsoft has shut down a long-running malicious extension operation on the Edge Add-ons store that hid its payloads inside ordinary image and font files, then woke up days after install to steal credentials and run ad fraud.
The company calls it StegoAd, a mash-up of steganography and adware, and ties 119 extensions to a single threat actor it says has been active since at least 2021.
A public proof-of-concept is now out for CVE-2026-55200, a critical flaw in libssh2 that lets a malicious or compromised SSH server trigger memory corruption on a connecting client, with possible code execution. No credentials, no user interaction. The bug affects every release up to and including 1.11.1 and carries a CVSS 4.0 score of 9.2.
libssh2 is a client-side SSH library, not a server.
Cybersecurity researchers have uncovered two hijacked npm packages and a cluster of Go packages that are designed to deploy a Python-based information stealer on compromised Windows, Linux, and macOS hosts.
"This attack avoids the most common npm execution paths through lifecycle scripts, perhaps in an attempt to remain 'compatible' with npm v12's security hardenings," JFrog said in a
The Security Service of Ukraine (SSU) said it, together with the U.S. Federal Bureau of Investigation (FBI), uncovered a long-running campaign orchestrated by Russian intelligence services to break into the messaging accounts of government officials, military personnel, politicians, and activists in Ukraine, Europe, and the U.S.

An active phishing campaign has been targeting hotel and other hospitality organizations across Europe and Asia since April 2026, using photo-themed ZIP files to drop a Node.js implant and dig into front-desk machines, Microsoft says.
The company has not attributed the activity to a known threat actor, and the operators' end goal is still unclear.
The lure plays to how hotels work.
Russian authorities used Cellebrite's UFED forensic tools to break into the iPhone of detained opposition activist Andrey Pivovarov in June 2021, three months after Cellebrite said it would stop selling its tools and services to Russia and Belarus.
The finding, published June 25 by the Citizen Lab, rests on two things that rarely line up: traces on the phone itself and an official Russian
The Russian state-sponsored threat actor known as Turla has been attributed to a previously undocumented .NET backdoor called STOCKSTAY that has been deployed against government and military organizations in Ukraine, and entities that have an interest in Italian foreign policy.

The extension description states that it allows users to prevent web
It’s dumb out there again.
This week has the usual smell of prod on fire and nobody wanting to admit who left the door open — old creds still working, trusted apps doing sketchy crap, browser tricks jumping the fence, and “normal” workflows turning into phishing pipes because apparently email was not enough hell already.
The worst part is how cheap some of it feels. Not elite. Not cinematic.
Despite the abundance of telemetry at analysts’ disposal, many security operations teams struggle to answer a few basic questions during incident investigation: What happened? What evidence do we have? How do we know we’re seeing it all, in context?
Answering these questions requires teams to go beyond alerts, the most common basis for initial triage. But investigations (and their outcomes)
A previously undocumented Rust-based macOS implant and information stealer has been found to embed a prompt injection payload designed to trick a malware analyst's artificial intelligence (AI) tools and trick it into aborting or refusing an analysis of the artifact.
The malware has been codenamed Gaslight owing to this deceptive behavior. It's been assessed with high confidence that the tool is
A new, stealthy backdoor named Mistic has been deployed as part of suspected financially motivated attacks aimed at multiple organizations spanning insurance, education, IT, and professional services sectors since April 2026.

The "critical exploitable pattern" has been codenamed Cordyceps by Novee Security. The issue can allow full attacker control of repositories at dozens of the largest organizations worldwide, including Microsoft, Google, Apache, and
We are standing at the end of an era we never thought to mourn: the era of human-speed threats.
For years, cybersecurity moved to a rhythm organizations could follow. A researcher found a bug, a CVE was cataloged, a vendor navigated a patch cycle, and weeks or even months later, a fix was deployed. In this era, dwell time was measured in days, sometimes weeks. We are now approaching an
The U.S. Department of Justice (DoJ) on Tuesday announced the seizure of a cloud computing account put to use by subsidiaries of Cambodia-based corporate conglomerate HuiOne Group, as the Treasury unveiled fresh sanctions against nine individuals and 26 entities linked to Prince Group.

A Russian-speaking initial access broker (IAB) driven by financial gain is assessed to be behind a large-scale credential-harvesting operation known as FortiBleed that has targeted over 430,000 FortiGate firewalls globally.
The campaign, active since February 2026, involves collecting credential lists, searching for exposed services, brute-forcing accessible systems, and deploying bespoke
Security firm AIR built a fake AI agent skill, pushed it through a popular skill marketplace and an Instagram ad, and says it reached roughly 26,000 agents, including some on corporate accounts.
Every skill security scanner the firm tested it against marked it safe. The payload was harmless by design: it collected the user's email address and did nothing else.
The point was to show
President Trump signed an executive order on June 22 setting hard deadlines for federal agencies to move high-value assets and high-impact systems to post-quantum cryptography.
Key establishment must move by December 31, 2030; digital signatures by December 31, 2031. EO 14409 leaves national security systems on a separate track.
The deadlines matter because of a threat that does not
GitHub is moving to strengthen software supply chain security by updating "actions/checkout" to block pwn request attacks that exploit the risky use of the "pull_request_target workflow" trigger to run malicious code with the workflow's full privileges.
Effective June 18, 2026, the latest version of "actions/checkout," the official GitHub action for checking out a repository into the
Every weapon begins as an extension of the hand that holds it. The spear lengthened the reach of the arm. The bow sent the point flying without the throw. The rifle placed a man's death a quarter mile beyond his sight, and the aircraft carried that death across oceans. At each turn, the distance between the warrior and the wound grew wider, and yet one thing never moved: a human chose the target

Google has set September 30, 2026, as the day it begins enforcing Android developer verification in the first four countries, and the major device-maker app stores are in from the start.
On that date, certified Android phones in Brazil, Indonesia, Singapore, and Thailand will block normal installs of apps whose developers have not registered an identity with Google, whether the app
Earlier this month, I spoke at the Gartner Security & Risk Management Summit about a blind spot most security programs are still not accounting for - how attackers are circumventing AI security programs by using legacy infrastructure to hijack AI agents.
AI adoption is moving faster than security programs can account for. Roughly 71% of organizations are piloting AI agents across their
It’s Monday again.
This week’s threat list looks painfully familiar: abused integrations, fake tools, poisoned websites, ransomware crews trying to shut down security tools, and mobile malware asking for way too much control.
The annoying part is how little of this feels new. Weak credentials, sketchy downloads, browser extensions with too much access, and WordPress sites are used to push more
Canada's spy service got a judge's permission to reach into infected servers, home routers, and IoT gear sitting on Canadian soil and neutralize two foreign-run botnets.
The Federal Court released a public version of the ruling on June 15. It is the first time the Canadian Security Intelligence Service has used its threat reduction warrant powers this way.
The warrant let CSIS alter,
A new malware family is turning forgotten home routers into a distributed reconnaissance and proxy network, not the DDoS botnet these devices usually end up in. QiAnXin's XLab calls it AryStinger and counts at least 4,300 infected routers, a total it says is still rising.
The distinction matters. AryStinger exists for the stage of an attack that comes before the break-in. Infected
A new report from INTERPOL has revealed a "dramatic increase" in cybercrime in Asia and the South Pacific, fueled by rapid digitalization, internet penetration, new technologies, organized criminal networks, and a disparity in cybersecurity maturity.

Introduction
The average enterprise security team has 40 or more security tools, giving a lot of visibility into internal telemetry and asset data. But often, these tools are working in siloes, generating (overlapping) alerts and data. And yet, breach dwell times remain stubbornly long (~43 days), response windows keep closing before teams can act, and analysts burn out triaging noise instead
The first wave of enterprise AI concern was straightforward. It was simply employees pasting sensitive data into public AI tools. Security teams responded with usage policies, domain blocks, and data loss prevention rules. That response made sense at the time.
It doesn't fit the problem anymore.
Shadow AI has shifted from a data leakage concern to an access control problem. The threat isn't
Salesforce has revealed that it disabled the Klue Battlecards app integration within its platform in response to a security incident impacting the competitive intelligence company on June 11, 2026.
