In August 2024, national background-check broker National Public Data confirmed a breach that leaked roughly 2.9 billion rows of personal records — names, addresses, relatives, SSNs — covering plausibly every US adult and parts of the UK and Canada, after a criminal actor first offered the data for sale in April and a third party then dumped 277GB free. This account traces the broker supply chain that assembled the dossier, the class-action lawsuit that forced acknowledgment, and the post-SSN security posture every organization now needs.

On July 19, 2024, a routine sensor configuration update from CrowdStrike passed staged testing and rolled through the Falcon channel to roughly 8.5 million Windows hosts — and crashed them into Blue Screens of Death, grounding flights, halting broadcasters and hospitals in the largest IT outage in history. This account reconstructs the flawed content-deployment pipeline, the Channel File 291 logic that sent the kernel into chaos, the 78-minute Remediation and guidance HHCfollows, the blame theater that followed, and why the incident rewrote every argument about single-vendor concentration risk.

On July 31, 2024, AT&T confirmed its customer data — including call and text metadata of nearly all subscribers and some SSNs — had been stolen off Snowflake’s cloud via compromised service-account credentials, and that it had paid roughly $370,000 to the SQlMap-scanning crew known as ShinyHunters to delete it. This account reconstructs the credential theft, the infostealer-to-Snowflake kill chain, the economics of a mid-six-figure ransom, and the quarterly-burial of accountability between carrier, and its data-warehouse vendor.

On June 28, 2024, TeamViewer disclosed that a state-sponsored actor — widely reported as Russia’s APT29 — had breached its corporate IT network through a standard employee’s credentials, and that the remote-access product itself, and every customer, stayed untouched. This account reconstructs the hours-to-containment timeline, explains why corporate/product segmentation carried the day, places the intrusion in Cozy Bear’s patient espionage season, and draws the anti-SolarWinds comparison that made this 2024’s most instructive breach.

When Sansec disclosed in late June 2024 that the polyfill.io domain had been sold and its hosted script rewritten to inject mobile-only scam redirects, hundreds of thousands of embedded sites — WordPress themes among them — discovered they had inherited an implant, invisible to desktop QA by design. This account traces the Funnull acquisition chain, the conditional payload mechanics, Cloudflare’s mirror intervention, the DNS-harassment retaliation, the 2025 arrests, and the inventory lesson every site owner still owes themselves.

Brain Cipher vs Indonesia’s Data Centers: A National Ransomware Reckoning

In June 2024, the Brain Cipher crew — running a LockBit 3.0 builder clone — encrypted Indonesia’s National Data Center, disrupting 200+ government services from immigration to licensing, then released a decryptor with an apology-flavored admission that extortion failed, then hit again during recovery. This account covers the copycat-crew economics behind the operation, why one shared-tenant data center meant national outage, the second-encryption lesson about persistence, and the segmented-architecture rebuild Indonesia promised next.

On June 19, 2024, Mandiant’s public advisory named UNC5537 as the crew behind the Snowflake extortion wave — 165+ victim organizations entered with infostealer credentials against MFA-less tenants, datasets extorted through listings and a dedicated leak market researchers dubbed Snow:Bay. This piece condenses the TTP catalogue, the backyard economics of stolen logs, the aftermarket that changed notification obligations forever, and the single control that would have prevented every confirmed intrusion.

Snowflake-Ticketmaster: The Cloud-Secure Myth Breaks

Live Nation’s May 2024 SEC filing confirmed criminal access to roughly 560 million Ticketmaster customer records — taken not by exploiting Snowflake but by logging into it with infostealer-derived credentials on a tenant without MFA. This account explains the UNC5537 tradecraft that chained $20 stealer logs into Fortune-500 data lakes, why the ‘no Snowflake breach’ defense only half-worked, what the ~560M-record dataset contained, and the mandatory-MFA wave that reshaped SaaS identity through 2024.

PuTTY ECDSA Nonce Bias: How 71 Signatures Exposed Your SSH Key

PuTTY’s April 2024 advisory for CVE-2024-31497 read like a physics problem: the terminal’s ECDSA implementation biased nonces on NIST P-521, so roughly 71 captured SSH signatures suffice for a lattice attack that recovers the private key. This piece explains the Hidden Number Problem math, why archived PCAP and DLP session capture retroactively weaponized years of traffic, the 0.81 deterministic-nonce fix, and the brutal rotation drill that made every P-521 key used through Pageant presumptively burned.

AT&T 73M Leak: The 2019 Dataset That Resurfaced Free

March 2024’s 73-million-record AT&T leak was an old wound reopened: a 2019-era vendor-workspace dataset, shopped unsuccessfully in 2021, finally dumped free on a hacking forum with SSNs and account details intact. This account disentangles it from the concurrent Snowflake campaign, explains why free publication maximizes criminal utility, maps the 7.6 million passcode resets, and follows the extortion thread that later surfaced in DOJ filings.

The most patient supply-chain attack ever caught — a two-year maintainer infiltration that planted an SSH backdoor into xz-utils release tarballs, discovered in March 2024 only because one engineer noticed 500 milliseconds of latency. This account traces the Jia Tan persona from helpful contributor to release engineer, the test-file obfuscation and build-stage injection, the systemd/sshd target chain, the near-miss that kept stable distros clean, and the trust-model reforms that rippled through open source.

February 2024’s Operation Cronos seized LockBit’s infrastructure across a dozen countries — and then the leaks showed how long the FBI had been inside. This account covers the covert access, the sting timing driven by UK hospital targeting, the servers and affiliate accounts taken down, the hurried rebrand to LockBit 4.1, the affiliate diaspora to RansomHub and Akira, and the awkward questions the takedown’s trolling raised about reading crime statistics.
