The Cybersecurity Defenders Podcast
LimaCharlie
An accessible but technical podcast about cybersecurity and the people who keep the internet safe. The podcast is built as a series of segments: we will be looking back at the last couple of weeks in cybersecurity news, talking to different people in the industry about areas of their expertise, we're going to break apart some of the TTPs being used by adversaries, and we will even cover a little bit of hacker history.

#184 - Hacker Holidays: The Colonial Pipeline
In this episode of The Cybersecurity Defenders Podcast, we recount some hacker history, and with the help of Casey Ellis, Founder and CSO at Bugcrowd, tell the story of the largest critical infrastructure ransomware attacks in history: The Colonial PipelineOn May 7, 2021, Colonial Pipeline, an American oil pipeline system that originates in Houston, Texas, and carries gasoline and jet fuel mainly to the Southeastern United States, suffered a ransomware cyberattack that impacted computerized equipment managing the pipeline. The Colonial Pipeline Company halted all pipeline operations to contain the attack. Overseen by the FBI, the company paid the amount that was asked by the hacker group (75 bitcoin or $4.4 million USD) within several hours; upon receipt of the ransom, an IT tool was provided to the Colonial Pipeline Company by DarkSide to restore the system. However, the tool required a very long processing time to restore the system to a working state.This episode was written by the talented Nathaniel Nelson.Casey Ellis can be found on LinkedIn here.

#183 - Hacker Holidays: When the lights went out in Ukraine (Part 1 & 2)
On this episode of The Cybersecurity Defenders Podcast, we share both parts of 'When the Lights Went Out in Ukraine.'Beginning on January 13th, 2022, a Russian APT installed wiper malware on the IT networks of government, NGO, and IT companies across Ukraine. The malicious program was designed to appear like ransomware, but contained no recovery feature – it simply destroyed any computer it wished.
Just one day later, hackers from the intelligence service of Belarus – Russia’s close ally – took down 70 websites belonging to the Ukrainian government.
This was tilling – laying down the foundation for an all-out ground attack. Plastered on the 70 downed websites was a message from the attackers: “be afraid,” they wrote,
and expect the worst.”This episode was written by the talented Nathaniel Nelson, narrated by Christopher Luft, and produced by the team at LimaCharlie.And a special thank you to Robert Lipovsky for sharing his first-hand knowledge.

#182 - Hacker Holidays: Stuxnet (Part 1 & 2)
This episode of the Cybersecurity Defenders podcast is a two-part mini-series about the greatest cyber attack ever conceived: Stuxnet.
Joining to help us tell the story is Kim Zetter, Journalist and Author - Countdown to Zero Day: Stuxnet and the Launch of the World's First Digital Weapon.
Stuxnet is a malicious computer worm first uncovered in 2010 and thought to have been in development since at least 2005. Stuxnet targets supervisory control and data acquisition (SCADA) systems and is believed to be responsible for causing substantial damage to the nuclear program of Iran. Although neither country has openly admitted responsibility, the worm is widely understood to be a cyberweapon built jointly by the United States and Israel in a collaborative effort known as Operation Olympic Games. The program, started during the Bush administration, was rapidly expanded within the first months of Barack Obama's presidency.
