IRIS C2 Zero-Day Marketplace: How Two Convicted Fraudsters Jack Berkman and Jacob Wohl Launched a Government-Facing Exploit Trading Operation

IRIS C2, a newly emerged Virginia company, has drawn scrutiny from cybersecurity journalist Brian Krebs for its bold claims of purchasing zero-day vulnerabilities and selling offensive cyber tools to governments while being led by two individuals with documented histories of fraud and deception.

The firm appeared on social media in January 2025 and quickly began publishing content about vulnerabilities, artificial intelligence, and hacking tools. On its website, IRIS C2 presents itself as a provider of offensive cyber capabilities based in McLean, Virginia, offering rewards ranging from $10,000 to $7 million for zero-day exploits, exploit chain components, and fully developed attack tools targeting major software platforms.

The company actively recruits young researchers skilled at finding vulnerabilities and developing exploits, emphasizing that formal education or prior work experience is unnecessary and that talent and high intelligence are the primary criteria. According to data from the government contracting portal G2Exchange, the IRIS C2 website is managed by Calvexa Group LLC, a registered federal contractor in Virginia, although no direct government contracts appear in public records.

Founders' Criminal Background and Deceptive Practices

The address of Calvexa Group is linked to lobbyist Jack Berkman, who directed inquiries about IRIS C2 to his longtime partner Jacob Wohl. Both men have previously created fictitious intelligence companies, disseminated false accusations against American politicians, and participated in illegal robocall campaigns.

In 2022, Berkman and Wohl pleaded guilty to wire fraud charges in Ohio, receiving fines, probation, and community service. The Federal Communications Commission later imposed a $5.1 million penalty on the pair for robocall operations that spread false information about mail-in voting.

Wohl told KrebsOnSecurity that IRIS C2 initially focused on penetration testing before shifting to selling phone-hacking tools to government entities. He stated that the company takes vulnerabilities discovered by external researchers and develops them into stable, practically usable attack tools. Approximately 40 employees work at the firm, with instructions not to list IRIS C2 on LinkedIn, although independent verification of staff numbers has not been possible.

Neither Wohl nor Berkman holds formal education in computer science or information security; Wohl claims to have acquired the necessary knowledge independently. Earlier, the pair operated LobbyMatic, a platform allegedly using artificial intelligence for political lobbying, where they concealed their real identities from employees and clients, leading several staff members to resign upon discovering the true leadership.

In March 2026, journalist Molly White reported that Berkman and Wohl received $300,000 from an individual accused of stealing $65 million from cryptocurrency platforms KyberSwap and Indexed Finance, in exchange for efforts to secure a presidential pardon.

Vulnerability in Docker go-archive Library Allows File Creation and Overwrite Outside Target Directory

A vulnerability has been identified in the go-archive archive processing library used by Docker and related software. The flaw, tracked as CVE-2026-17106, affects the Unpack, UnpackLayer, and Untar functions and permits files to be created or overwritten outside the intended extraction directory. The issue stems from a mismatch between the path string validated by the code and the actual path resolved by the operating system. Docker rated the vulnerability 7.1 under CVSS v4.0 and classified it as High severity. A proof-of-concept exploit has already been published for macOS and Linux. The fix was implemented in go-archive 0.3.0 and shipped in Docker Engine 29.7.0, Docker CLI 29.7.0, and Docker Desktop 4.86.0.

Microsoft Defender Zero-Day ShieldBreak Enables SYSTEM Privilege Escalation, Bypassing July Rogue Planet Patch

Security researcher Nightmare Eclipse has publicly disclosed a new zero-day vulnerability named ShieldBreak in Microsoft Defender that allows any standard Windows account to escalate privileges directly to SYSTEM level. The flaw exploits a TOCTOU race condition in Defender's file scanning API callbacks, enabling attackers to swap file contents during the brief window when the scanner reads the file. Although linked to the earlier Rogue Planet vulnerability (CVE-2026-50656), the July patch did not fully address the attack surface, and an adjusted proof-of-concept continues to work on patched systems. Defender's high privileges and trusted status in enterprise environments amplify the risk, as compromised processes can execute malicious actions that appear legitimate in logs. Public disclosure without prior private reporting leaves a window of exposure until Microsoft issues an official fix. Blue teams are advised to enforce strict local permissions, monitor for anomalous Defender process behavior such as unusual child processes or repeated file handle operations, and implement layered defenses including application whitelisting and network segmentation.

CISA Adds Two Remotely Exploitable TrueConf Server Vulnerabilities to KEV Catalog

The US Cybersecurity and Infrastructure Security Agency has added two critical vulnerabilities affecting TrueConf Server to its Known Exploited Vulnerabilities catalog. CVE-2026-72529 allows unauthenticated remote attackers to execute arbitrary scripts due to missing authentication in a critical function. CVE-2026-72530 is a code injection flaw that enables attackers to run arbitrary code on the underlying host system by escaping the sandboxed environment. Both issues can be exploited over TCP port 4307 without requiring authentication. Kaspersky assigned CVSS v3.1 base scores of 9.8 and 9.0 respectively, rating both as Critical. US federal agencies must apply mitigations for the first vulnerability by August 23 and for the second by September 3.
