Remember to keep your passwords close and your eyes peeled – cybersecurity is everyone’s responsibility.
Health Tech, SonicWall News: Healthcare was the second most targeted industry for malware last year, according to SonicWall’s 2023 Cyber Threat Report. Internet of Things (IoT) malware attacks in healthcare increased 33 percent.
Verdict, SonicWall News: Immanuel Chavoya from SonicWall told Verdict the recent data breach happened due to an exposed “Amazon S3 bucket”.
Chavoya explains that they are able to be “accessed, altered, or even deleted by anyone who knows where to look and that breaks the core tenants of confidentiality integrity, and availability. However, sometimes, in the process of configuring a bucket, someone might unintentionally set the permissions to allow public access,” Chavoya said.
“For example, they might be trying to make it easier for a team to share files, or they might not realize the implications of making a bucket public,” Chavoya explained. “Unfortunately if sensitive data is stored in the bucket – which it was in this case, this can lead to a data breach. Therefore, it’s crucial to properly configure S3 bucket permissions and regularly review them to ensure they are still appropriately configured.”
eSecurity Planet, SonicWall News: There are the potential data privacy concerns arising due to the collection and storage of sensitive data by these models,” said Peter Burke, who is the Chief Product Officer at SonicWall. Those concerns have caused companies like JPMorgan, Citi, Wells Fargo and Samsung to ban or limit the use of LLMs. There are also some major technical challenges limiting LLM use.
“Another factor to consider is the requirement for robust network connectivity, which might pose a challenge for remote or mobile devices,” said Burke. “Besides, there may be compatibility issues with legacy systems that need to be addressed. Additionally, these technologies may require ongoing maintenance to ensure optimal performance and protection against emerging threats.”
CIO Influence, SonicWall News: According to Glair, a company will never be able to train every person to spot every threat. That comes down to the sheer volume of novel threats being created. In fact, in the first half of 2022, SonicWall detected 270,228 never-before-seen malware variants. That’s an average of 1,500 new variants per day.
Security Boulevard, SonicWall News: Immanuel Chavoya, SonicWall’s emerging threat expert, noted that the accord ushered in a new approach to cybersecurity that is based on cooperation and information sharing. “The introduction of a U.S./South Korea ‘Strategic Cybersecurity Cooperation Framework’ fundamentally alters the global cybersecurity landscape. It exemplifies a shift from siloed defenses to collective global security, fortifying the digital ecosystem against threats by pooling resources, intelligence and expertise,” Chavoya said. “This sends a message to nation-state actors like DPRK: The world’s cyberdefenders are uniting against threat actors who leverage our digital interconnectedness to disrupt our daily lives, making every digital interaction a new front line in this asymmetric war. As we often say, the best offense is a good defense—and in this case, it’s a defense extending traditional alliances across continents and cyberspace alike.”
CRN, SonicWall News: In many cases, these “extortion-only” attacks are a more lucrative and easier alternative to the process of encryption and negotiation that’s involved in a typical ransomware attack, CrowdStrike’s threat intelligence head told CRN recently. SonicWall, meanwhile, cited extortion-only groups including Lapsus$ and Karakurt as further evidence of the trend.
The Record, SonicWall News: Despite falling digital asset prices, cryptojacking reached record levels in 2022, according to research from cybersecurity firm SonicWall.
Rouble Malik Sheds Light On The Rising Threat Of Cybersecurity Attacks On Smes And Advocates Stronger Protective Measures
TechBullion, SonicWall News: The 2022 Cybersecurity Threat Report by SonicWall indicates a 62% increase in global ransomware attacks, demonstrating the evolving sophistication and prevalence of malware-based threats.
ITPro, SonicWall News: Immanuel Chavoya, senior manager of product security at SonicWall told ITPro that the latest update highlights the potential long-term impact that this breach could have on Capita partner organizations.
The outsourcing giant provides services for both public and private sector clients, including the UK Ministry of Defence. “Cyber attacks such as the one on Capita require a bit of long-tail analysis to capture a clear understanding of impact, but what is known is that the ripple effect of a cyber attack like the one on Capita can be far-reaching, extending beyond the organization itself to shake customer trust, disrupt essential services, and reverberate throughout communities.”

0mega Ransomware Gang Pulls Off First-of-its-kind Attack
A ransomware group named 0mega has completed an attack against a company’s SharePoint Online environment without using a compromised endpoint. This is bad news for companies who have been pouring money into endpoint protections in the hopes of thwarting ransomware attacks – this attack proves that these criminals can complete an attack without ever compromising an endpoint. The attack was pulled off by the gang using some weakly secured administrator credentials they acquired. After infiltrating, the threat group exfiltrated data from the company’s SharePoint environment and then used that data to extort them. The CPO at the security firm that discovered the attack said this attack shows that strong endpoint security isn’t enough. With many companies storing data in online Software-as-a-Service (SaaS) programs, this type of attack may become more common although this attack appears to be the first of its kind. 0mega completed the attack by using the stolen credentials to create an Active Directory user named ‘0mega’ and giving it all of the permissions needed to turn the unnamed company’s day upside down. Many cybersecurity researchers are noticing an uptick in SaaS attacks. Organizations can protect themselves by being proactive, creating strict MFA policies and ensuring they have robust risk management tools in place across their SaaS environments.
LockBit Ransomware Gang Extorted Over $90 million from 1,700 Attacks in the US
Cybersecurity authorities from the United States and around the world issued a joint advisory on the notorious LockBit ransomware gang stating that the gang had extorted $91 million in 1,700 attacks on organizations in the U.S. since 2020. The advisory also noted that LockBit was the most deployed ransomware variant in 2022 and continues to be widespread in 2023. According to Bleeping Computer, LockBit has released two major new versions of its Ransomware-as-a-Service (RaaS) tool since 2019 and is currently on LockBit 3.0. Since releasing LockBit 3.0, the gang has committed multiple high-profile attacks using the upgraded tools and extortion tactics in the newest version. The advisory released this week by CISA includes tips, tools and tactics to help organizations protect themselves from LockBit.
Russian Member of LockBit Ransomware Gang Arrested in Arizona
A 20-year-old man named Ruslan Magomedovich Astamirov was arrested in Arizona this week following his involvement in multiple attacks with the LockBit ransomware gang. The man allegedly participated in attacks against the United States, Asia, Europe and Africa. Astamirov’s case will be tried in New Jersey where the cases of two other men involved with LockBit are being handled. Prosecutors filed a complaint accusing Astamirov of owning and controlling IP addresses, email addresses and a cloud services account that were found to be connected to LockBit’s attacks. This is the latest development in what has become a global crackdown on the LockBit ransomware gang with CISA and global law enforcement agencies releasing a joint document this week specifically to combat LockBit. Let’s hope they can continue to have success with bringing these threat actors to justice.
The US Government Buys Your Data in Bulk
A recently declassified government report confirms something people have been wondering about for years now – yes, the United States government does purchase your personal data. The report notes that various U.S. intelligence and spy agencies purchase huge amounts of data on American citizens including web browser data, smartphone data and data from connected vehicles. In the report, the U.S. government itself states that this is a significant issue for citizens’ privacy and civil liberties. While it’s unknown exactly which agencies are buying this data and for what purpose, we do have at least one example. The Internal Revenue Service apparently purchases the location data of millions of Americans in order to catch people cheating on their taxes. The Department of Homeland Security purchases the same type of information to enforce immigration laws. While it isn’t necessarily shocking that the U.S. government is collecting this data, it’s worth noting that typically a search warrant is required for the government to obtain this type of data on an individual. Now it can just load up its proverbial shopping cart with your data and flip through it like the morning news.
