On September 5, 2024, Transport for London detected an intrusion begun days earlier through social engineering of staff — and within a week a 17-year-old was arrested, then charged under the Computer Misuse Act, for a breach that exposed contact details and the bank details of roughly 3,000 Oyster refund customers. This account reconstructs the phishing entry, the lateral movement, the containment that took status boards and the refund portal offline, the NCSC-NCA response, and the municipal-security lessons that outlasted the headlines.

On August 21-22, 2024, SolarWinds shipped 12.8.3 HF1 for Web Help Desk and disclosed CVE-2024-28986 — an unauthenticated Java deserialization flaw rated CVSS 9.8 that delivers pre-auth remote code execution on internet-facing instances. Within days PoC code circulated in exploitation attempts, and on August 26 CISA added it to the Known Exploited Vulnerabilities catalog, making patching mandatory across federal networks. This account covers the bug mechanics, the four-day disclosure-to-KEV sprint, and the uncomfortable optics of a SolarWinds product back in emergency-cycle headlines.

On August 24, 2024, French authorities arrested Telegram founder Pavel Durov at Le Bourget airport, and two days later charged him with complicity in organized-crime offenses enabled by his platform’s refusal to cooperate with legal process — the first time a major encrypted-service executive faced criminal liability for governance choices. Released under judicial supervision within days, Durov’s case forced every platform lawyer to reprice jurisdictional arbitrage, moderation staffing, and the meaning of cooperation. This account lays out the charges, the encryption-policy fault lines, and the compliance playbook that followed.

At DEF CON 32 in August 2024, SafeBreach’s Alon Leviev unveiled Downdate — a technique that abuses the Windows Modules Installer, TrustedInstaller privileges,and deliberately-eased vbsm manifest permission to silently roll back fully-patched Windows binaries to vulnerable prior versions, re-opening fixed BitLocker bypasses and Hyper-V escapes on current builds. This account explains the downgrade mechanics, the CVE-2024-21430 fix timeline, and why the research redefined patch currency as a security property worth defending.

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 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 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 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.

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.

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.
