Symantec Cyber Security Brief Podcast
Our regular podcast series features threat research and security news, hosted by threat researchers from the Threat Hunter Team.
In the latest Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss some of the recent research published by Symantec’s Threat Hunter Team, including our blog about the activity of North Korean APT group Stonefly, and our latest whitepaper on the topic of Commodity Malware. We also talk about some stories that were in the news over the last week or so, including the possible return of the REvil/Sodinokibi ransomware gang, a new loader called Bumblebee that might be a successor to BazarLoader, and a China-on-Russia intelligence-gathering attack.
On this week’s Cyber Security Brief, Brigid O Gorman is joined by Symantec threat researchers John-Paul Power and Alan Neville. In this week’s podcast we discuss some recent research published by Symantec detailing new activity in the Dream Job campaign carried out by the North Korean Lazarus APT group, as well as continuing attacks aimed at Ukraine carried out by the Russia-linked APT group Shuckworm. Also, we talk about a critical vulnerability in the Windows Remote Procedure Call Runtime (RPC) protocol, the shut down of two well-known dark marketplaces, and the emergence of a new marketplace offering stolen data for sale.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss some of the research published by Symantec’s Threat Hunter team over the past couple of weeks, including a new Cicada/APT10 espionage campaign targeting government organizations and NGOs in multiple countries worldwide. We discuss the new Verblecon malware, which is being deployed in sophisticated campaigns that appear to have the relatively low-reward goal of cryptocurrency mining as their main objective. We also talk about the Spring4Shell vulnerability that briefly caused a lot of consternation last week, and give an update about the latest information that has emerged about the cyber activity that has been seen targeting organizations in Ukraine.
In this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien talk about extortion hacking group Lapsus$, which has made headlines in recent weeks by claiming to have compromised numerous high-profile companies including Microsoft, Okta, and Nvidia. We tell you what we know so far about this controversial new actor. We also discuss the impact the Russian invasion of Ukraine has had in the world of cyber security, from Russia potentially running out of data storage facilities due to international cloud providers pulling out of the country, to warnings about attacks on critical infrastructure being issued by authorities in the U.S. and the UK. Finally, the BazarBackdoor malware is seen deploying some new tactics.
In this special edition of the podcast, Dick O’Brien is joined by Symantec threat researchers and analysts Piotr Krysiuk and Vikram Thakur to discuss the Symantec Threat Hunter team’s discovery of Daxin, which is the most advanced piece of malware we have seen from China-linked actors. We published a blog about the discovery of Daxin last week, as well as two in-depth technical blogs with more information on the tool this week. Piotr discusses his work analyzing the malware, and when he realized the significance of this discovery, while Vikram talks about liaising with customers impacted by the malware as well as working with the Cyber Security and Infrastructure Security Agency (CISA) to engage with multiple foreign governments targeted with Daxin to assist with detection and remediation.
In this week’s Cyber Security Brief podcast, Brigid O Gorman and Dick O’Brien discuss some of the activity we saw in Ukraine prior to the escalation of the last couple of days. We also heavily cover ransomware in this podcast, including discussing a recent FBI alert about the BlackByte ransomware, and a possible decryptor for the Hive ransomware, as well as some research into how long ransomware gangs are remaining active for these days and the amount of money they are making. Finally, we also discuss how BEC scammers are leveraging virtual meeting platforms in their attacks.
In this week’s Cyber Security Brief podcast, Dick O’Brien and Alan Neville discuss how Chinese state-backed advanced persistent threat (APT) group Antlion targeted financial institutions in Taiwan in a persistent campaign over the course of at least 18 months. Also up for discussion is the recent arrest of a New York couple and the seizure of $3.6 billion in cryptocurrency allegedly linked to the 2016 Bitfinex hack, as well as continuing attacks carried out by the Russia-linked Shuckworm APT group against targets in Ukraine.
In this week’s Cyber Security Brief podcast, Dick O’Brien and Brigid O Gorman discuss the tumultuous situation in Ukraine, where cyber attacks, including destructive cyber attacks, have been aimed at government and private sector organizations. The WhisperGate attacks, as they have been dubbed, have been compared by many to the infamous 2017 NotPetya wiper attacks. Also up for discussion is recent law enforcement activity aimed at cyber criminals in Russia and elsewhere, and some ransomware news, including a Noberus ransomware attack, and the FBI officially linking the Diavol ransomware to the creators of Trickbot and Conti.
Welcome to the first Cyber Security Brief of 2022! In this week’s podcast, Dick O’Brien and Brigid O Gorman chat about some of the biggest news stories of the last couple of weeks. The topics up for discussion in this episode include: FIN7 BadUSB attacks return, an interesting new multi-platform backdoor, and the latest way attackers are attempting to abuse Google Docs. Also, a jump in the number of extortion DDoS attacks, how payments to suspicious cryptocurrency wallets have exploded in recent months, corruption of open source libraries as a form of protest, and how one APT group managed to infect itself with its own malware.

Meanwhile, we also talk about a blog we published covering details about a new Rust-based malware we have dubbed Noberus (ALPHV/BlackCat). This is our last Cyber Security Brief podcast of 2021, we will be back on January 13.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss the latest Symantec blog, some updated research about the Yanluowang ransomware gang, with fresh activity appearing to show that this ransomware isn’t a flash-in-the-pan. We also discuss how quickly exposed cloud services are compromised by malicious actors, how off-putting strong passwords are for attackers employing brute-forcing techniques, and apparent attempts by Russian hackers to collaborate with Chinese-speaking actors. Also, the Conti gang’s possible role in the return of Emotet, and North Korean actors continue to target security researchers with fake job offers.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss some recent attack campaigns aimed at critical infrastructure organizations in several countries around the world, the possible return of the Emotet botnet, and some law enforcement activity that has led to the arrest of people involved with both the REvil and Gandcrab ransomware. We also discuss some new techniques being used by the BazarLoader gang, and an FBI system being compromised and used to send out fake information security alerts.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss some of our recent blogs, including at least one BlackMatter ransomware affiliate using a new data exfiltration tool in attacks, and also the breaking news that the BlackMatter ransomware operation is apparently winding down. We also discuss another recent blog we published about banking Trojan activity in Latin America, while recent law enforcement activity cracking down on ransomware criminals is also up for discussion. Elsewhere, we also talk about SquirrelWaffle, a reasonably new malware that is used as a loader and has been mentioned as a potential successor to the notorious Emotet for the delivery of threats.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss several new blogs that the Symantec Threat Hunter Team has published recently. Firstly, we uncovered a new ransomware threat that we dubbed Yanluowang, which appears to be deployed in a targeted fashion and is certainly a new threat as various indications point towards it still being in development. We also published two blogs detailing two separate campaigns targeting organizations in Asia. The Harvester group is a previously unknown, likely nation-state backed group targeting victims in South Asia, while elsewhere a new espionage campaign is targeting the defense, healthcare, and ICT sectors in South East Asia. Meanwhile, we also discuss new activity from a targeted attack group dubbed LightBasin, and the return of the Lyceum group.
On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss how the UK and the U.S. are planning to increase their efforts to tackle cyber crime, ransomware being blamed in court for the death of a baby, and the arrests of some ransomware criminals in Ukraine. Also, the Conti ransomware gang makes some threats, evidence of the Pegasus spyware allegedly found on the phones of French cabinet ministers, and an interesting targeted phishing campaign.
We are back for Season 4 after our summer break, and on this week’s Cyber Security Brief podcast Dick O’Brien and Brigid O Gorman spend a lot of time discussing the subject that also dominated the last season of the podcast - ransomware. We discuss some of the ransomware stories we missed while we were off air, as well as a ransomware whitepaper we recently worked on and made available to our customers. Apart from ransomware, we also discuss Mēris - a huge botnet that emerged over the summer and has aimed massive DDoS attacks at various organizations around the world.
