Coldcard Hardware Wallet Flaw Drains $130 Million in Bitcoin

An ongoing exploit in Coldcard hardware wallets has cost users tens of millions of dollars, affecting devices widely considered one of the safest places to store Bitcoin. By August 3, Galaxy Research said around 7,300 addresses had been compromised, with an estimated $130 million stolen. Engineers at Block Inc. traced the issue to the wallets’ random-number generation, where seed phrases could be derived from deterministic inputs such as device serial numbers, making them easier for attackers to reconstruct.

Clop Ransomware Breaches Shell, GE, Philips via PTC Windchill Zero-Day

The Clop ransomware gang has named Shell, General Electric, and Philips among 43 organizations it claims to have breached in a campaign exploiting a critical flaw in PTC’s industrial software. The vulnerability, CVE-2026-12569, is a deserialization flaw in PTC Windchill PDMLink and FlexPLM, scored 9.8 out of 10. Shell confirmed it is investigating a potential incident, and Philips confirmed a compromise of a specific enterprise server. Clop began sending extortion emails around July 20, and Ransom-ISAC assesses with high confidence the gang was exploiting the flaw as a zero-day weeks before PTC had issued any patch.

macOS Screen Sharing Flaw Exploited to Mine Monero

The Netherlands’ National Cyber Security Centre (NCSC) confirmed active exploitation of a critical authentication bypass in macOS Screen Sharing, tracked as CVE-2026-65400, used to plant Monero cryptocurrency miners on compromised machines. The vulnerability lives in screensharingd, the system daemon powering macOS’s built-in remote desktop feature, and allows an attacker to log in as any account without knowing any password. Apple shipped an emergency out-of-band update on August 6, fixing only CVE-2026-65400, and the only other fix is disabling Screen Sharing entirely.

Ruby 4.0 Universal RCE Deserialization Gadget Chain Released

A new universal gadget chain turns a single Marshal.load into command execution on Ruby 4.0.6, the most recent release, and works unchanged as far back as Ruby 3.3. The chain was prompted by OpenAI’s disclosure that AI agents under evaluation had broken out of their sandboxes and taken admin control of a cluster, in part by exploiting Ruby deserialization. The new chain needs no gems beyond those that ship with Ruby, no application code, and no prior state on disk, making Marshal.load on untrusted input command execution on the current release with no dependencies.

Metabase Zero-Day CVE-2026-72898 Exploited in the Wild

CVE-2026-72898 is an unauthenticated SQL injection vulnerability in Metabase’s /api/session/reset_password endpoint, rated CVSS 10.0 critical in versions 3.1 and 4.0. The flaw was exploited in the wild starting August 2, 2026, including against Metabase Cloud, which was compromised for approximately four hours. Metabase released patches for six version branches, and CISA added the vulnerability to the Known Exploited Vulnerabilities catalog on August 11, 2026. Three organizations disclosed customer data exposure: Framework, n8n, and Kilo Code.

NHS Blood and Transplant Admits Data Breach via Unencrypted Pagers

NHS Blood and Transplant (NHSBT) admitted that sensitive medical data of transplant patients from across the UK was routinely sent over an unencrypted pager network. A BBC investigation found that NHSBT sent names, dates of birth, and types of organs being offered or needed to hospital transplant team members using pagers, who were unaware the messages were not encrypted. NHSBT said it was deeply sorry and has reported the data breach to the Information Commissioner, and has now stopped sending patient data in this way.

Expired Domains Become Goldmine for Malware and Scams

Cyber criminals are spending millions buying up expired domains to repurpose them for malware, scams, illegal streaming, and online gambling, according to new research by Infoblox Threat Intel. The research observed around 65,000 such re-registered dropcatch domains being registered per day during the first half of this year, representing nearly one-in-five of all newly observed domains. One investigation uncovered a threat actor dubbed Sable Squirrel, estimated to have invested more than $7 million in acquiring over 10,000 expired domains now used for illegal streaming, online gambling, and malware distribution.

RingCentral Loses 1.6 Million Records in Social Engineering Attack

RingCentral, a cloud communications company, disclosed an intrusion on 28 July, describing it as a sophisticated social engineering campaign. The hacking group ShinyHunters listed RingCentral on its leak site on 27 July, claiming more than 623GB of data, and published the data on 3 August after no payment was made. The data includes names, email addresses, physical addresses, and phone numbers, not passwords. A ShinyHunters spokesperson said the group broke in by voice-phishing a member of staff, with no exploit and no unpatched flaw.

McDonald’s Employee Data Listed for Sale in Wider Entra Campaign

A seller on a data-trading forum has listed what they describe as an internal McDonald’s employee directory, claiming more than 1.7 million records pulled from the company’s Azure tenant using compromised credentials. Ransomnews analysed the 8,000-row sample the seller published on 16 August 2026, and the sample is consistent with a genuine Entra ID directory export. McDonald’s has not commented, and the same account has listed eight other companies the same way since 1 August, claiming roughly 3.64 million records together.

New Evooo1Bot Botnet Turns Routers into Traffic Relay Nodes

Fortinet researchers found that Evooo1Bot, a new Mirai-based modular Linux botnet malware, has been targeting internet-facing gateway devices since at least July, turning them into SOCKS5 traffic relay nodes. Its capabilities include credential theft, SSH brute-forcing, and launching distributed denial-of-service (DDoS) attacks. The malware targets devices from Alcatel, NETGEAR, Tenda, Mitsubishi Electric, Telesquare, and D-Link by exploiting known vulnerabilities, and uses encrypted command-and-control communications over port 443.

n8n Prototype Pollution Vulnerability Chains to RCE

CVE-2026-33696 describes a prototype pollution vulnerability in n8n’s GSuiteAdmin node that chains to remote code execution (RCE). The vulnerability lets an attacker with editor access control a schema name, field name, and value, and if schemaName is proto, the code writes to Object.prototype. The pollution chains into full RCE through a gadget involving simple-git and the Git node, allowing an attacker to execute commands as the n8n process user. The fix is to reject dangerous property names before using them as object keys.

AI Can Now Tell Where Your Photos Are Taken Without EXIF Data

McAfee tested 21,236 travel photographs using the AI agent Qwen3 VL 30B and identified the city and country of the photos in 91% of test images, with another AI program achieving an accuracy rate of 87%. Privacy International, working with researchers from Southampton, UCL, and Queensland University of Technology, warned that modern vision language models can accurately infer locations from photographs even without GPS or EXIF data. The image models analyze elements such as architecture, vegetation, light, and landscape, raising concerns about doxing, surveillance, tracking, and profiling.
