ATF confirms cyberattack hit system containing info on its investigation targets

Qilin ransomware group claimed breaching the ATF, exposing data on investigation targets; the agency says a standalone system was hit with no mission impact.

The Bureau of Alcohol, Tobacco, Firearms and Explosives confirmed a cyberattack on a standalone system holding information about targets of ATF investigations, designated a major incident, with no impact on case management, lab, or eForms systems. Qilin, a Russian-speaking affiliate-based ransomware group, claimed responsibility, though ATF declined to confirm involvement or the root cause. Qilin has claimed hundreds of victims across 60+ countries since 2022 and partners with Scattered Spider and Moonstone Sleet.

DOJ firearms agency says hackers breached system containing investigation targets

ATF confirmed a cyberattack on a standalone system containing investigation target data, calling it a major incident; Qilin listed ATF on its leak site.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) confirmed a cyberattack on a standalone computer system containing information about targets of ATF investigations, with no connection to case management, laboratory, or eForms systems. The agency designated the breach a major incident and immediately terminated connections, initiating incident response and forensics. The Qilin ransomware gang added ATF to its leak site without providing stolen data samples. Qilin was the second most active ransomware gang in July 2026 with 127 reported attacks, and has previously hit Kuala Lumpur International Airport, Asahi, and Palau's government.

Leaks, data breaches, and ransom notes: The worst hacks of 2026 so far

TechCrunch's 2026 roundup covers SSA data exposure, Iranian water-utility attacks, Klue breach hitting ~200 firms, and Meta AI chatbot account hijacks.

TechCrunch's mid-year roundup highlights a whistleblower claim that DOGE uploaded a live Social Security database copy to an unsecured third-party server, which House Democrats called potentially the largest US breach in history. CISA reported Iranian hackers targeted over 100 US water providers over the summer, while Russian-linked attacks hit Polish, Swedish, and Norwegian energy and water infrastructure. Market research firm Klue was breached via a stale 2022 pilot credential, exposing cloud keys of ~200 customers including Jamf, HackerOne, and LastPass to extortion gang Icarus. Separately, tens of thousands of Instagram accounts were hijacked by abusing Meta's AI chatbot to trigger password resets to attacker-controlled emails.

Risky Bulletin: Two TeamPCP members arrested in Australia

Australian Federal Police arrested two alleged TeamPCP members behind supply-chain worm attacks that stole over 500,000 credentials from compromised open-source libraries.

The AFP arrested alleged TeamPCP leader Ruben Thomson, 21, and Louis Gaebler, 23, near Perth; both were charged and remain in custody. The group inserted a self-spreading credential-stealing worm into open-source projects including Trivy, KICS, LiteLLM, and Telnyx, harvesting more than 500,000 credentials used for network access, ransomware, extortion, and sales. About 78,000 tokens and secrets from nearly 2,200 organizations leaked online last month, and the FBI supported the investigation that began in April.

Microsoft discloses two actively exploited zero-days among 974 vulnerabilities

Microsoft patches 974 flaws in record Patch Tuesday, including two actively exploited Windows zero-days enabling privilege escalation.

Microsoft's largest-ever Patch Tuesday addresses 974 vulnerabilities, with CVE-2026-81963 (Windows Update Stack) and CVE-2026-85880 (Windows Advanced Local Procedure Call) exploited before disclosure. Both zero-days carry CVSS 7.8 ratings and allow privilege escalation. More than 10% of the defects are rated critical, and researchers attribute the record volume to AI-assisted vulnerability discovery without a matching rise in active exploitation.

In most cities, nobody owns the whole network

Former Waco CIO argues cellular-connected water controllers sit outside scanned networks, and accountability plus operating-budget funding—not technology—block segmentation.

Writing as Waco, Texas's former CIO, the author describes July water-sector intrusions that CISA linked to over 100 compromised systems, typically controllers on public cellular links absent from asset lists. The FBI and EPA reported incidents at utilities in at least seven states since July 27, and a Clayton County, Georgia pump station failure triggered a boil-water advisory. He argues accountability and funding—using mechanisms like the Texas Water Development Board's new cybersecurity scoring criteria—are the binding constraints, citing Waco's 43-day segmentation of five treatment plants with operating funds.

European parliament members call for slowdown of Serbia’s EU entry over spyware use

29 MEPs urge delaying Serbia's EU accession after researchers found Pegasus and NoviSpy spyware on student activists' phones.

Twenty-nine Members of the European Parliament sent a letter Friday demanding Serbia's EU accession be slowed until an investigation into its spyware use is completed. The letter follows a SHARE Foundation report, with Amnesty International and the Citizen Lab, documenting Pegasus and NoviSpy infections on Serbian student activists' phones; NoviSpy evidence pointed to Serbian government authorities, though Pegasus attribution was not assigned. The MEPs also urged European Commission President Ursula von der Leyen to cancel a planned visit to Serbia and called the surveillance 'a direct state attack on democracy' ahead of upcoming elections. The Serbian government did not respond to requests for comment.

Attackers exploit zero-days in consistently besieged SonicWall product

Two actively exploited SonicWall SMA 1000 zero-days chain to unauthenticated RCE; patches released and CISA added both to KEV.

SonicWall disclosed and patched two zero-days in SMA 1000 appliances: CVE-2026-83548, a maximum-severity pre-authentication SSRF, and CVE-2026-83549, a high-severity OS command injection. Rapid7 said chaining the flaws yields unauthenticated remote code execution, and CISA added both to its KEV catalog Wednesday. The vendor provided no IOCs or victim counts, urging customers to hunt for compromise, reimage or redeploy appliances, and reset all passwords and tokens. The product has faced repeated exploitation, including ransomware-linked flaws used by INC and Akira.

Pegasus, NoviSpy variant spyware found on devices of Serbian activists

Researchers confirmed the first 2026 Pegasus infection and a new NoviSpy variant on 14 Serbian activists, likely surveillance by Serbian authorities ahead of elections.

Citizen Lab confirmed with high probability the first forensically confirmed Pegasus infection of 2026, on a Serbian student activist hacked via a zero-click exploit between December of last year and January. Amnesty International confirmed two devices infected with a new NoviSpy variant, and the SHARE Foundation documented 14 targets including a member of parliament and a local government official, the largest documented spyware wave in Serbia to date. Evidence points to Serbian police or intelligence services, with NoviSpy infections occurring around police detention ahead of key local and parliamentary elections. Apple threat notifications preceded the findings, and updated iOS versions break the exploit chain.
