I'm (finally) moving our organization towards more decision-based risk analysis rather than just "it's risk! omg!" Starting with software reviews in the acquisition process.

What are folks using for quantitative modeling? I'm thinking simple models that take into account organizational track record (aka number of x incidents in y timespan), industry track record (average of z incidents) and some kind of weighting factor.

I have a few options. I can hire a contractor to build some excel models for us. I can spend some money on a software tool, with some work if it's more than $1k. Or I can invest in books / pluralsight / etc to teach myself quantitative analysis, which will take longer to get done.

What're you folks using for this kind of stuff?

• DeceptiveDevelopment targets freelance software developers through spearphishing on job-hunting and freelancing sites, aiming to steal cryptocurrency wallets and login information from browsers and password managers.
• Active since at least November 2023, this operation primarily uses two malware families – BeaverTail (infostealer, downloader) and InvisibleFerret (infostealer, RAT).
• DeceptiveDevelopment’s tactics, techniques, and procedures (TTPs) are similar to several other known North Korea-aligned operations.

Angry Likho (referred to as Sticky Werewolf by some vendors) is an APT group we’ve been monitoring since 2023. It bears a strong resemblance to Awaken Likho, which we’ve analyzed before, so we classified it within the Likho malicious activity cluster. However, Angry Likho’s attacks tend to be targeted, with a more compact infrastructure, a limited range of implants, and a focus on employees of large organizations, including government agencies and their contractors. Given that the bait files are written in fluent Russian, we infer that the attackers are likely native Russian speakers.

We’ve identified hundreds of victims of this attack in Russia, several in Belarus, and additional incidents in other countries. We believe that the attackers are primarily targeting organizations in Russia and Belarus, while the other victims were incidental—perhaps researchers using sandbox environments or exit nodes of Tor and VPN networks.

At the beginning of 2024, several cybersecurity vendors published reports on Angry Likho. However, in June, we detected new attacks from this group, and in January 2025, we identified malicious payloads confirming their continued activity at the moment of our research.

Google Threat Intelligence Group (GTIG) has observed increasing efforts from several Russia state-aligned threat actors to compromise Signal Messenger accounts used by individuals of interest to Russia's intelligence services. While this emerging operational interest has likely been sparked by wartime demands to gain access to sensitive government and military communications in the context of Russia's re-invasion of Ukraine, we anticipate the tactics and methods used to target Signal will grow in prevalence in the near-term and proliferate to additional threat actors and regions outside the Ukrainian theater of war.

Signal's popularity among common targets of surveillance and espionage activity—such as military personnel, politicians, journalists, activists, and other at-risk communities—has positioned the secure messaging application as a high-value target for adversaries seeking to intercept sensitive information that could fulfil a range of different intelligence requirements. More broadly, this threat also extends to other popular messaging applications such as WhatsApp and Telegram, which are also being actively targeted by Russian-aligned threat groups using similar techniques. In anticipation of a wider adoption of similar tradecraft by other threat actors, we are issuing a public warning regarding the tactics and methods used to date to help build public awareness and help communities better safeguard themselves from similar threats.

We are grateful to the team at Signal for their close partnership in investigating this activity. The latest Signal releases on Android and iOS contain hardened features designed to help protect against similar phishing campaigns in the future. Update to the latest version to enable these features.

Carding — the underground business of stealing, selling and swiping stolen payment card data — has long been the dominion of Russia-based hackers. Happily, the broad deployment of more secure chip-based payment cards in the United States has weakened the carding market. But a flurry of innovation from cybercrime groups in China is breathing new life into the carding industry, by turning phished card data into mobile wallets that can be used online and at main street stores.

On December 31, cybercriminals launched a mass infection campaign, aiming to exploit reduced vigilance and increased torrent traffic during the holiday season. Our telemetry detected the attack, which lasted for a month and affected individuals and businesses by distributing the XMRig cryptominer. This previously unidentified actor is targeting users worldwide—including in Russia, Brazil, Germany, Belarus and Kazakhstan—by spreading trojanized versions of popular games via torrent sites.

In this report, we analyze how the attacker evades detection and launches a sophisticated execution chain, employing a wide range of defense evasion techniques.

How to visualize #server #metrics in #RealTime via #TCP in @LabPlot ?
