When we talk about the term "fake news," most people likely picture a certain person who made the term infamous.

And when we talk about misinformation and disinformation, many will remember the "Russian troll farms" that popped up during the 2016 U.S. presidential election and were unmasked and shut down during former president Barack Obama's final days in office.

But a few recent actions from TikTok, the most popular online social media platform, show that the problem of spreading misinformation and disinformation goes far beyond the borders of the U.S.

TikTok announced last week it was launching in-app "election centres" to help combat misinformation and inform users of facts when they view videos about elections in European Union nations. This includes 27 unique apps that all use the country's native language.

In a statement on their site, the social media company said this effort is to "ensure people can easily separate fact from fiction."

Part of me can't help but wonder if this wasn't a problem of the company's own creation after they allowed misinformation about the COVID-19 global pandemic to spread rapidly and use an algorithm that enhances "controversial" videos about different international brands. But I can certainly hope that these election centres provide more context than the little info box Twitter launched a while ago.

I think this is important to note, though, that this problem just goes beyond American culture. Fake news, disinformation, misinformation - whatever label you want to put on it - will not just go away if one election in the U.S. goes one way or the other. It is an issue that is spreading on all platforms in all countries.

I've been at fault in the past for just wanting to put the blame on Twitter. While they have been one of the worst offenders of allowing misinformation on their site, they are far from the only offenders or the only platform where users can spread this time of misinformation, even if they are doing it by accident.

Just like any other platform, it's easy for someone on TikTok to simply "share" or "like" someone else's video if they find it compelling without giving it a second thought. Your friends and family are likely spreading misinformation on their feeds without even knowing it or doing it with any malicious intent. Regardless of where you live in the world, this is likely true.

It's amplified in the U.S. because our political theater is such that when something happens, everyone else on the world stage notices it. I can't say that folks in the U.S. are necessarily invested in the national elections in Greece.

But if misinformation is allowed to spread during the Greek elections, it's going to spread to U.S. presidential elections. Once the infrastructure is in place for disinformation to flourish on a platform, it's nearly impossible to get rid of, no matter the topic.

The one big thing

Google Cloud Run is currently being abused in high-volume malware distribution campaigns, spreading several banking trojans such as Astaroth (aka Guildma), Mekotio and Ousaban to targets across Latin America and Europe. The volume of emails associated with these campaigns has significantly increased since September 2023 and we continue to regularly observe new email distribution campaigns. We have observed all three malware families being delivered during the same timeframe from the same storage bucket within Google Cloud.

Why do I care?

Some of the highest volume campaigns recently observed were being used to deliver the Astaroth, Mekotio, and Ousaban banking trojans to victims largely located in Latin American countries. We have also observed lower volume campaign victims located throughout Europe and North America, which may indicate less geographically focused targeting by threat actors moving forward. For example, the current variant of Astaroth targets more than 300 institutions across 15 Latin American countries.

So now what?

Talos has released new ClamAV signatures and Snort rules to protect against these various banking trojans. Our researchers have also alerted Google of this activity so that they may address it internally on Cloud Run.

Top security headlines of the week

Poland is launching a formal investigation into whether its former government leaders misused the Pegasus spyware. Parliament created a coalition to see if the Law and Justice (PiS) government, previously the ruling party of Poland, used the controversial spyware to track and target its political opponents. Current ruling leaders used a promise of an investigation as one of their top campaign platforms. Meanwhile, NSO Group, the creators of Pegasus, have reportedly created a new one-click exploit called "MMS Fingerprint" that it offers as an infection tool for the spyware. MMS Fingerprint allows Pegasus users to learn a great deal about a target Blackberry, iPhone or Android device by sending a specially crafted Multimedia Messaging Service (MMS) message. A contract between an NSO Group reseller and a customer in Ghana exposed the information, including a promise that MMS Fingerprint required "No user interaction, engagement, or message opening … to receive the device fingerprint."

The spyware startup Variston is reportedly shrinking and is preparing to completely close. Variston is known for launching spyware that can target iPhones, Android devices and some PCs. A disgruntled employee reportedly leaked information about the company and the zero-day exploits they used to Google's Threat Analysis Group, which allowed Google to unmask the operation. This eventually led to several employees and developers leaving Variston. Variston, founded in 2018, previously used three zero-day vulnerabilities to target Apple devices, including a campaign in March 2023 to target iPhones in Indonesia. Reporters and researchers have yet to find who, exactly, Variston sold their services and technology to, though former employees have said some of the spyware was sent to the United Arab Emirates.

Volt Typhoon, a large APT based in China, is reportedly still exfiltrating sensitive information on operational technology (OT) networks. Volt Typhoon has been known to target organizations in the communications, manufacturing, utility, IT and education sectors across the globe, though it's recently become more noteworthy for its targeting of critical networks in the U.S. A new report from cybersecurity firm Dragos says that it spotted Volt Typhoon conducting scanning activities against electric companies between November and December 2023. Volt Typhoon is traditionally known for espionage and data theft on behalf of the Chinese government. But Dragos also says that the actor has also recently infiltrated a large U.S. city's emergency services network, as well as critical infrastructure networks in Africa. The report states that the OT data stolen may cause "unintended disruption to critical industrial processes or provide the adversary with crucial intelligence to aid in follow-up offensive tool development or attacks against ICS networks."

S4x24** (March 4 - 27)**

Miami Beach, Florida

To protect themselves during Russian aggression, the Ukrainian military utilizes electronic warfare to blanket critical infrastructure to defeat radar and GPS-guided smart munitions. This has the unintended consequence of disrupting GPS synchrophasor clock measurements and creating service outages on an already beleaguered and damaged transmission electric grid. Joe Marshall from Talos' Strategic Communications team will tell an incredible story of how a group of engineers and security professionals from a diverse coalition of organizations came together to solve this electronic warfare GPS problem in an unconventional technical way, and helped stabilize parts of the transmission grid of Ukraine.
