Seven years ago today, Troy Hunt ( @troyhunt ) disclosed Collection #1, one of the largest known aggregations of breached credentials at the time.

👉 See Troy's original write-up on this finding: https://www.troyhunt.com/the-773-million-record-collection-1-data-reach/

Collection #1 showed how old breaches become new threats at scale when data is reused, automated, and repackaged. For deeper context on why this happens, we recommend two #CyberCanonHoF books published years before this incident.

⚡ 𝗧𝗼𝗱𝗮𝘆 𝗶𝗻 𝗖𝘆𝗯𝗲𝗿𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗛𝗶𝘀𝘁𝗼𝗿𝘆 – 𝗗𝗲𝗰𝗲𝗺𝗯𝗲𝗿 𝟮𝟯, 𝟮𝟬𝟭𝟱

On a cold December evening in Ukraine, the lights began to go out.

Not because of a storm or a fallen transmission line. But because an unseen adversary, who was patient, disciplined, and already deep inside Ukraine’s networks, made its move.

Inside three regional power companies, operators watched helplessly as their mouse cursors began to move on their own. Breakers opened. Substations went dark. And within minutes, 230,000 people were without power.

It was the world’s first confirmed blackout caused by a cyberattack.

In Sandworm, Andy Greenberg follows the trail back to the group behind it. An elusive GRU team whose operations would ripple across the globe. What makes this moment unforgettable isn't just the technical achievement of penetrating industrial control systems…

It’s that December 23rd proved a new reality: code could now disrupt cities, societies, and the physical world itself.

Greenberg’s investigative storytelling captures the tension, the human impact, and the geopolitical stakes behind an attack that forever changed how we think about cyberwar.

It started quietly, days before the holiday rush. Shoppers were filling stores, credit cards were swiping nonstop, and behind the scenes, a small foothold inside Target’s network was about to become one of the most infamous breaches in retail history.

💀 Attackers slipped in through a third-party HVAC vendor
🪲 Malware moved silently across point-of-sale systems
💳 40 million payment cards skimmed
🔏 70 million customers' data exposed

While many are (sadly) becoming numb to breach news nowadays, this disclosure, announced 12 years ago today, shook the industry. Boardrooms across the globe were confronted with the fact that cybersecurity wasn’t just an IT problem, but a critical business-wide issue.

The incident is covered very nicely in this Huntress article: https://www.huntress.com/threat-library/data-breach/target-data-breach

On November 24, 2014, Sony Pictures Entertainment experienced a landmark cyber-attack. A hacker group calling itself the “Guardians of Peace” unleashed destructive malware, wiped large portions of the studio’s network, and dumped terabytes of sensitive internal data.

On November 2, 1988, the Morris Worm became the first major computer virus to spread across the Internet. What began as a graduate student’s “experiment” quickly spiraled out of control, taking down much of the early Internet and costing millions in cleanup. It also gave rise to one of cybersecurity’s most important realizations: even well-intentioned code can cause catastrophic damage in a connected world.

To learn more, 𝙁𝙖𝙣𝙘𝙮 𝘽𝙚𝙖𝙧 𝙂𝙤𝙚𝙨 𝙋𝙝𝙞𝙨𝙝𝙞𝙣𝙜 by Scott Shapiro, a #CyberCanonHoFCandidate, covers the #MorrisWorm as one of its five infamous hacks. See our review ➡️ https://tinyurl.com/r2b3zc2u

💥And as a bonus, many may not be aware that 𝙏𝙝𝙚 𝘾𝙪𝙘𝙠𝙤𝙤'𝙨 𝙀𝙜𝙜 also contains an interesting perspective on the Morris Worm. A year after astronomer Cliff Stoll's spy tracking journey, he was one of many admins around the country who were investigating the Morris Worm live as it was spreading through the night. Cliff writes about this experience in the book's epilogue, where he discovers that the author of the worm was actually the son of NSA's Chief Scientist, Robert Morris, whom Cliff worked with in relation to his international hacker sleuthing a year earlier.

Did you know?

The first computer worm, 'Creeper', appeared in 1971. It moved across ARPANET, leaving a message in it's wake. Cybersecurity was born from this experiment.
