A ransomware attack has wreaked havoc inside the network of Tigo, the largest mobile operator and internet service provider in Paraguay.

The incident took place last Thursday, January 4, and impacted the telco's business branch.

Around 300 servers in Tigo's data center were encrypted, according to Miguel Ángel Gaspar, director of the Paraguay Ciberseguro Foundation.

Hackers associated with the Turkish government are conducting new cyber-espionage operations across Europe and the Middle East, according to recent reports from PwC, StrikeReady, and Hunt & Hackett.

Tracked as Sea Turtle (Teal Kurma, Silicon, UNC1326, Cosmic Wolf), the group rose to fame between 2018 and 2020 when it conducted a series of DNS hijacking campaigns that intercepted traffic for Cypriot, Greek, and Iraqi government systems.

Ever since its public ousting in late 2020, the group wound down its DNS hijacking infrastructure, and very little activity has been linked to its operations.

Ransomware gang arrest: Chinese police detained two individuals from Hohhot who were involved in ransomware attacks against Chinese organizations.

In this podcast, Patrick Grey and Tom Uren talk about whether election interference will take place in the Taiwanese, US, and Russian elections that are all taking place in 2024. They also look at a ChatGPT-powered online harassment campaign.

FBI disrupts AlphV ransomware: US authorities have hacked and seized server infrastructure operated by the AlphV (BlackCat) ransomware gang. Authorities say they also recovered 500 encryption keys, which they are now offering together with a decrypter to all affected victims. This confirms rumors from last week.

AI Act: EU authorities have agreed on a first version of the AI Act, a law meant to regulate artificial intelligence development and tools across the EU.

UK sanctions Asian scammers: The UK government has sanctioned nine individuals and five entities for their involvement in trafficking people in Cambodia, Laos, and Myanmar and forcing victims to work in call centers specialized in cyber fraud (also known as "pig butchering scams"). These are the first-ever sanctions levied against online scam operations.

FBI SEC reporting rules: The FBI has published a guide on how companies that suffered a security breach should report their incidents to the SEC and other authorities. The guide comes after a ransomware gang tried to use the confusion around these new rules to put pressure on a victim as part of their ransom negotiations.

The UK government has summoned Russia's ambassador to explain a years-long hacking campaign conducted by one of the FSB's cyber units.

Officials say that FSB hackers targeted politicians and government organizations and attempted to use hacked data to influence and interfere in UK politics.

The UK government statement connects—for the first time—an APT group known as Star Blizzard to Center 18, a cybersecurity division inside Russia's FSB intelligence agency.

There are three major elections taking place in 2024: in Taiwan, the United States and Russia. So, what are the chances that we'll see cyber-enabled disruption campaigns targeting each of these polls? In the case of the upcoming US election it seems inevitable.

Election interference techniques take many forms. At the 'lowest' level are information operations on social media that spread disinformation and propaganda. In the context of an election, these types of operations tend to get lost in the noise.

At the 'highest' level of severity there is the possibility of direct interference in the electoral process: messing with the actual votes. In theory, this could shape the outcome of an election, and even unsuccessful attempts undermine the perceived legitimacy of election outcomes.

An audit of 23 of the largest US federal agencies found that most have failed to implement proper event logging and may be unprepared to respond to cybersecurity incidents, especially during the investigation and remediation phase.

Conducted by the US Government and Accountability Office, the report found that 20 of the 23 agencies did not meet a White House executive order mandating they reached a logging level of EL3 by August 2023.

GAO says that only three agencies reached the proper requirement, while 17 were still at EL0 and had not made any headway toward compliance.

ICANN, the non-profit organization that manages domain names and IP addresses, has launched a new service to help law enforcement agencies and cybersecurity professionals obtain redacted and non-public data on domain owners.

Named the Registration Data Request Service (RDRS), the service works as a ticketing system that interconnects investigators with domain registrars—the smaller organizations that manage each TLD domain space.

The new system is designed to create private communication channels where investigators can file requests with domain registrars in a more centralized fashion.
