Magecart’s 2024 Resurgence: Skimming in the Polyfill.io Aftermath

Through 2024, digital skimming returned to threat reports’ front pages: Magecart-style attacks compromised hundreds of storefronts via compromised third-party JavaScript, supply-chain infections like polyfill.io’s June domain takeover injected malicious scripts into vast numbers of pages, and PCI DSS 4.0’s script-integrity requirements (6.4.3 and 11.6.2) approached their March 2025 enforcement deadline. This survey digests the modern skimming kill chain — injection, exfiltration, and evasion — the major 2024 campaigns, and the compliance clock turning client-side risk into boardroom math.

F5 BIG-IP Next Central Manager: The Unauthenticated Takeover Bugs

On November 6, 2024, F5 disclosed a pair of critical bugs in BIG-IP Next Central Manager shipped in its SPK fabric: CVE-2024-23327, an unauthenticated privilege-escalation path reachable via REST API, and CVE-2024-23328, a missing-authentication flaw letting attackers create arbitrary administrator accounts. Together they enable full takeover of a management node that itself commands a fleet of application delivery hardware. This account walks both paths, the same-day patches, and the uncomfortable lineage going back to CVE-2022-1388’s iControl REST flaw.

Ivanti Endpoint Manager RCE: Two Bugs, One Dangerous Chain

On October 16, 2024, Ivanti disclosed two vulnerabilities in Endpoint Manager (EPM) chained for pre-auth remote code execution: CVE-2024-29224, an unauthenticated SSRF rated 9.6, and CVE-2024-29226, a path traversal in a downstream service. The week’s disclosure calendar placed it days after FortiManager’s FortiJump and amid a year of Ivanti security crises — from January’s Connect Secure zero-days to September’s Cloud Service Appliance flaw. This account explains the chain mechanics, why consortium defenders pushed urgent patching, and the management-plane pattern of 2024.

FortiManager Zero-Day (FortiJump): CISA Escalation Explained

On October 23, 2024, Fortinet confirmed CVE-2024-47575 — a CVSS 9.8 missing-authentication flaw in the FortiManager FGFM protocol that China-nexus actor UNC5850 had exploited since summer to jump from exposed managers into fleets of managed FortiGates with a custom DeepMove implant. CISA KEV-listed it within days, forcing two-week patch deadlines across federal and enterprise fleets. This account reconstructs the protocol bug, the DeepMove persistence, the fleet-jump blast radius, and the management-plane hardening it made mandatory.

CUPS RCE: The Linux Printing Story That Went Viral Before CVEs Landed

In late September 2024, researcher Simone Margaritelli disclosed a chain of CUPS vulnerabilities — CVE-2024-47076, CVE-2024-47176 and siblings — allowing same-network attackers to register malicious printers and achieve code execution as the lp user via broadcast-trusting auto-configuration. Preceded by a hype-teaser countdown that split the community, the episode became the year’s clearest study in disclosure-process dysfunction, severity theater, and the quiet ubiquity of trust-the-LAN daemons. This account covers the chain mechanics, the honest exposure math, and what to disable today.

TfL 2024: A 17-Year-Old, a Social Engineer’s Approach and Oyster Chaos

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.

SolarWinds Web Help Desk RCE: The Name That Hurts Again

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.

The Telegram Arrest and the Encryption Debate of 2024

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.
