Week in review: Claude accounts compromised through infostealer, Patch Tuesday forecast

Help Net Security week-in-review roundup: Claude infostealer lockouts, record Patch Tuesday, McKesson breach, SonicWall zero-days, PaperCut attacks.

This Help Net Security weekly roundup aggregates prior stories: Anthropic locking out Claude users after infostealer-compromised login sessions, August 2026 Patch Tuesday's 398 resolved CVEs, ShinyHunters' claim of 284 million stolen patient records from McKesson, active exploitation of SonicWall SMA 1000 zero-days (CVE-2026-83548/83549), Sangoma Switchvox SQL injection exploitation (CVE-2026-9586), and attackers planting RATs on compromised PaperCut servers. It also covers FBI OAuth phishing warnings, a Spring Ring vishing campaign abusing Microsoft Teams, and a fake Claude Opus 5 GitHub repo delivering RevStealer infostealer.

Open-source secrets scanning tool Sift hunts credentials in Microsoft 365, Slack, and Jira

Stratus Security open-sourced Sift, a CLI secrets scanner covering Active Directory, SharePoint, Teams, Slack, Jira, and Confluence, outperforming Snaffler in benchmarks.

Stratus Security released Sift, a free open-source command line tool that hunts passwords, API keys, and sensitive data across local disks, Windows shares, Active Directory, SharePoint, OneDrive, Teams, Slack, Jira, and Confluence. In the firm's benchmarks, Sift scanned 250,000 files in 10.61 seconds versus Snaffler's 25.48 and averaged 92 MiB memory versus Snaffler's 337 MiB. Optional false-positive filtering runs through a local language model via Ollama, and scans write checkpoints so interrupted runs resume. The tool found thousands of credentials in Jira ticket comments that prior pentesting had missed.

  • Pre-Authentication SSRF in SonicWall SMA1000 Appliance Workplace Interface
    CVE-2026-83548 is a critical (CVSS 3.1 score 10.0) server-side request forgery (SSRF) vulnerability in the Workplace interface of SonicWall SMA1000 appliances, caused by an unintended alternate access path (unprotected alternate channel, CWE-441; SSRF, CWE-918). Because it is pre-authentication, any remote unauthenticated attacker who can reach the interface can trigger it and gain unauthorized access to sensitive functionality and perform unauthorized operations. CISA lists all SonicWall SMA1000 appliances as affected, with CPE data naming the SMA 8200v and SMA 6210/7210 firmware; internet-exposed units are at highest risk. The flaw is being actively exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-02 alongside companion zero-day CVE-2026-83549, which reporting suggests may form an attack chain with this SSRF. Exploitation probability is elevated (EPSS 4.7%, 91st percentile) and no public proof-of-concept is known.

  • Unauthenticated SQL Injection RCE in Sangoma Switchvox SMB Edition
    Sangoma Switchvox SMB Edition 8.3 (build 104997) contains an unauthenticated SQL injection flaw (CWE-89) in its /pa endpoint, where the user-controlled PhoneIP value from XML input is concatenated directly into PostgreSQL queries without sanitization or parameterization. A single crafted request lets a remote, unauthenticated attacker execute arbitrary SQL statements against the backend PostgreSQL database, which can be escalated to remote code execution on the server. Any organization running the affected Switchvox SMB Edition build is exposed, especially appliances reachable from the internet. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV catalog on 2026-09-02, and researchers have observed attackers using it without credentials to deploy reverse shells and cryptocurrency miners.

  • Authenticated OS Command Injection RCE in SonicWall SMA1000 Appliance Console
    CVE-2026-83549 is a post-authentication OS command injection flaw (CWE-78) in the Appliance Management Console (AMC) of SonicWall SMA1000 appliances. An attacker who authenticates to the AMC with administrator privileges can, under specific conditions, inject arbitrary operating system commands and achieve remote code execution on the appliance. Only organizations running SMA1000-series appliances, including the SMA 6210, SMA 7210, and SMA 8200v models cited in the data, are affected. CISA added the flaw to the KEV catalog on 2026-09-02, and news reports describe active exploitation, possibly chained with companion zero-day CVE-2026-83548, with reverse shells and cryptocurrency miners observed; no public proof-of-concept is known. EPSS assigns an 8.5% probability of exploitation within 30 days (95th percentile).

  • Capture-Replay Authentication Bypass in Microsoft Exchange Server
    Microsoft Exchange Server contains an authentication bypass flaw (CWE-294) in which captured authentication material can be replayed, allowing an authorized attacker to elevate privileges over a network. Per the CVSS vector, the attack is network-based with low complexity but requires the attacker to already hold low privileges and some user interaction, and success yields high impact on confidentiality, integrity, and availability. Affected products include on-premises Exchange Server and Exchange Server Subscription Edition, though specific vulnerable version ranges are not specified in the available data. Public scans indicate nearly 22,000 Exchange servers remain exposed to the flaw following the August 2026 Patch Tuesday fixes. No in-the-wild exploitation, public proof-of-concept, or KEV listing is known; the bug was demonstrated at Pwn2Own (ZDI-26-534) and carries an EPSS estimate of 1.3% probability of exploitation within 30 days.
