JetBrains Cadence user data from a 2024 server backup was accessed during the August 2026 intrusion, putting credentials, project source code, and other stored records at risk of exposure. JetBrains said attackers reached data tied to current Cadence users and treated the stored material as potentially exposed. The company also invalidated Cadence plugin access tokens and told users to revoke or rotate all credentials. The exposure raises immediate risk of account abuse and follow-on phishing using the affected contact data.

The ClickFix payload now uses a WebRTC data-channel stager that opens a covert encrypted channel and executes received code in the browser, increasing stealth for visitors of compromised sites. The new variant replaces the earlier smart-contract payload and pulls JavaScript from a hardcoded C2 address. It buffers the code in memory and runs it when the channel closes or after ten seconds, avoiding disk writes. The change sits inside a broader delivery chain spread across thousands of hacked websites.

A massive cybercriminal operation is using more than 5,400 hacked websites to spread ClickFix payloads through EtherHiding on BNB Smart Chain (BSC), giving the delivery chain durable infrastructure. The compromised sites are mostly WordPress and PrestaShop installations, and the operation has expanded to more than 300 infected websites every day. The scale and persistence point to a continuing delivery campaign rather than a one-off compromise.

Metabase CVE-2026-72898 is a critical SQL injection flaw that was exploited as a zero-day, creating immediate risk for exposed Metabase deployments. The flaw was linked to a breach affecting ShipMonk systems and downstream customer data exposure.

Threat actors are actively exploiting PaperCut CVE-2026-81578 and CVE-2026-82078, putting schools and universities in the U.S. and Europe at risk of credential theft and follow-on compromise. Arctic Wolf observed the chain being used for command execution, reconnaissance, and privileged account creation on vulnerable servers. Post-exploitation activity also included registry hive collection tools, Meterpreter Java payloads, and searches for passwords, secrets, ldap, bind, and token values in PaperCut configuration files.

A reported IDScan data leak exposed or offered for sale more than 153 million driver’s license scans, putting large volumes of identity documents at risk. The cache was advertised by the dark-web service Nexus, and sample checks tied the material back to IDScan. The exposure increases the risk of identity theft, impersonation, and fraud for people whose IDs were scanned through businesses using the service.

Multiple lawsuits were filed in Louisiana against IDScan over an alleged breach tied to more than 153 million driver’s licenses, expanding civil exposure around scanned identity data. Several law firms have also begun investigating possible class-action litigation for people whose IDs may have been scanned through IDScan-linked businesses. The cases could consolidate if additional claimants come forward.

A high-volume phishing campaign is using invisible Unicode tag characters to split lure words and bypass email filters, pushing finance-themed emails at scale. The activity first surfaced in early February 2026 and later reached 1 to 2.37 million messages on weekdays. A broader linked operation used ActiveCampaign to distribute AI-generated phishing emails targeting Small Business Administration loan applicants. The evasion technique increases the odds that malicious emails reach recipients and can complicate reputation-based filtering.

PostgreSQL shipped a security update for CVE-2026-6471, closing a logical-decoding code-execution flaw that can let a REPLICATION-privileged account run code as the database server’s OS user. The fix covers PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 and introduces output_plugin_libraries to restrict which logical-decoding plugins can load. Administrators using non-default plugins such as wal2json or decoderbufs must add them to the allowlist and reload configuration after updating.

CVE-2026-6471 in PostgreSQL logical decoding lets a user with the REPLICATION attribute run code as the database server OS user, and fixed builds are now available. The flaw affects versions before 18.6, 17.11, 16.15, 15.19, and 14.24 and requires wal_level = logical. PostgreSQL added output_plugin_libraries to whitelist allowed logical-decoding plugins and block arbitrary library loading. Administrators running replication features should update and review which plugins their slots depend on.

The newly identified ted Linux implant was compiled into trojanized HAProxy load balancers, giving operators a way to intercept web traffic and serve altered pages on affected hosts. The backdoor also concealed its C2 activity from ordinary counters while supporting file transfer, shell execution, and configuration changes. The implant was found on two South Korean organizations in the automotive and media sectors, with only medium-confidence attribution to a North Korean cluster.
