The self-spreading Miasma worm, a variant of the Shai-Hulud malware linked to the group TeamPCP, has reached Microsoft's own code. Using a stolen access token, attackers pushed a malicious commit into the Azure durabletask repository, and GitHub disabled 73 repositories across four Microsoft organizations including Azure and MicrosoftDocs. The twist: the planted code runs automatically when a developer opens the project in an AI coding assistant like Claude Code, Cursor, Gemini CLI, or VS Code, then harvests cloud and developer credentials and uses them to infect more projects. It hides the trigger inside a build file (binding.gyp) that most security tools ignore.
Baker Distributing, one of the largest US wholesalers of heating, cooling, and refrigeration equipment, has been hit by the extortion group ShinyHunters, which stole company data and posted it after the company did not pay. Breach-tracking service Have I Been Pwned has now confirmed 102,935 affected accounts; the gang originally claimed more than 260,000 stolen records pulled from Salesforce and internal SharePoint sites, including HR documents. ShinyHunters has been on a tear this year, breaking into corporate SaaS accounts by tricking IT help desks into resetting credentials. Exposed personal and business data fuels follow-on phishing aimed at Baker's customers and staff.
Researchers at Include Security have shown how a software kit made by Bright Data, embedded inside free apps on Samsung, LG, and Roku smart TVs, quietly turns those always-on devices into relays for someone else's web-scraping traffic. Users opt in through a consent screen buried in the TV's menu, then their home internet connection is used to fetch web pages for Bright Data's paying customers, many of them AI firms. The researchers found the control channel barely checks who is issuing commands, weaker than many malware families, and on iPhones the traffic even slips past VPNs and normal monitoring tools.
Security firm ESET has detailed a new Android spyware it calls Asin that targets Arabic-speaking users, likely journalists and open-source investigators. Victims are lured to convincing fake websites posing as a government news service, a secure PDF reader, and live war-map tools, some promoted through Facebook and Telegram pages. The sites offer apps such as GovLens, WarMap, and Syria Defense Map that work as advertised but hide spyware underneath. Because the apps come from outside official stores, victims must manually install them and grant permissions. ESET has not tied the campaign to a known group, and its exact goals remain unclear.
A critical flaw in Zcash's Orchard privacy pool, the system that lets people send the ZEC cryptocurrency while hiding amounts and parties, could have let an attacker mint unlimited counterfeit coins without detection. Security researcher Taylor Hornby, hired by developer Shielded Labs to probe the code, found it on May 29 using Anthropic's Claude Opus 4.8 model paired with a custom auditing tool, and wrote a working exploit within a day. The bug had survived four years and multiple expert reviews. An emergency fix shipped by June 1. Because the pool hides balances, there is no way to prove whether anyone exploited it earlier.
With the FIFA World Cup kicking off June 11 across the US, Canada, and Mexico, the FBI and researchers at Group-IB and Fortinet warn that a large fraud operation is already running. Group-IB tracked more than 4,300 fake FIFA websites and a Chinese-speaking crew, GHOST STADIUM, that cloned the official site pixel-for-pixel, fake login and all, across 300-plus domains. Scams include bogus ticket, merchandise, and hospitality sites, fake streaming apps that hide banking malware, and betting sites that harvest passport scans for identity theft. With tickets scarce and 150 million requests filed, scammers are exploiting fans' urgency to steal logins, money, and personal data.
Cisco has warned of an actively exploited, unpatched zero-day in Cisco Catalyst SD-WAN Manager (CVE-2026-20245) that enables root privilege escalation across all deployment types, including on-prem, Cloud, Managed, and FedRAMP Government. The flaw stems from insufficient validation of user-supplied input: an attacker who uploads a crafted file can perform command injection and run arbitrary commands as root. Exploitation requires netadmin privileges - obtained via valid credentials or by chaining CVE-2026-20182 or CVE-2026-20127. Mandiant reported the activity to Cisco's PSIRT in June. Cisco has observed limited cases where exploitation pushed configuration changes to edge devices, and published IoCs pointing to suspicious tenant-list uploads in scripts.log.
CISA has warned that attackers are actively exploiting CVE-2026-28318, a high-severity SolarWinds Serv-U denial-of-service flaw, and added it to the Known Exploited Vulnerabilities catalog. Serv-U is SolarWinds' Windows and Linux managed-file-transfer and FTP software. The flaw is an uncontrolled-resource-consumption weakness: specially crafted POST requests using Content-Encoding: deflate crash the Serv-U service without authentication, in low-complexity attacks needing no user interaction. SolarWinds shipped Serv-U 15.5.4 Hotfix 1 and advised admins who cannot patch to restrict access and block POST requests containing content-encoding. Shodan tracks over 12,000 exposed Serv-U servers (Shadowserver around 3,100). FCEB agencies must patch by June 19 under BOD 22-01.
Volexity has detailed Chinese espionage group UNC5221 (also VerdantBamboo) maintaining access to a victim's Microsoft 365 environment using the Brickstorm backdoor plus previously undocumented malware named Plenet and AgentPSD. The actor sat on the network at least 18 months before detection and had also compromised the victim's MSP. UNC5221 has exploited edge-device zero-days since at least 2023; Brickstorm began as Golang, later Rust. In this case the group pivoted from a compromised Egnyte Storage Sync system through the victim's SSL VPN, then used Brickstorm proxying and stolen credentials to reach Microsoft 365 - deliberately blending with legitimate traffic to evade Conditional Access. It re-breached the org after remediation.
ReliaQuest has documented OP-512, a China-linked espionage cluster targeting Microsoft IIS web servers with a bespoke web-shell framework - the fourth such group after CL-STA-0048, DragonRank, and GhostRedirector to single out IIS in the past year. The framework uses three web shells that grant remote access while evading signature detection and complicating forensics: each deployment is uniquely generated, access is cryptographically restricted to the attacker, and compromised servers auto-report to centralized management. To hide, the web shells timestomp - scanning surrounding files, computing the median last-modified time, and overwriting their own timestamps to match. ReliaQuest notes close tactical proximity to CL-STA-0048, suggesting a revamped toolset or shared development.
