Banking Trojans in a business wrapper

www.kaspersky.com/blog/icedid-qbot-banking-trojans-in-spam/40552/ Spammers are using malicious macros to distribute IcedID and Qbot banking malware in seemingly important documents. For employees facing hundreds of e-mails, the temptation to speed-read and download attachments on autopilot can be great. Cybercriminals, of course, take advantage, sending out seemingly important documents that might contain just about anything from phishing links to malware. Our experts recently discovered two very similar spam campaigns distributing the IcedID and Qbot banking Trojans.

Where do all those cybercrime payments go?

nakedsecurity.sophos.com/2021/07/09/where-do-all-those-cybercrime-payments-go/ Here on Naked Security, weve regularly asked the question, or at least implied it: Where do you think all those cybercrime payments go?. When a ransomware victim hands over a largely anonymous, mostly untraceable quantity of Bitcoin, for example, to pay off a multi-million dollar blackmail demand in the hope of recovering their unusable files. what happens to that money?

Dont Be Rude, Stay: Avoiding Fork&Run .NET Execution With InlineExecute-Assembly

securityintelligence.com/posts/net-execution-inlineexecute-assembly/ Some of you love it and some of you hate it, but at this point it should come as no surprise that .NET tradecraft is here to stay a little longer than anticipated. The .NET framework is an integral part of Microsofts operating system with the most recent release of .NET being .NET core. Core is the cross-platform successor to the .NET Framework that brings .NET to Linux and macOS as well. This now makes .NET more popular than ever for post exploitation tradecraft among adversaries and red teams.

Ransomware: To pay or not to pay? Legal or illegal? These are the questions

www.welivesecurity.com/2021/07/08/ransomware-pay-not-pay-legal-illegal-these-are-questions/ The recent spate of ransomware payments cannot be the best use of cybersecurity budgets or shareholder capital, nor is it the best use of insurance industry funds. So, why are companies paying and what will it take for them to stop?. In simple terms, it may just be, or at least initially seem, more cost effective to pay than not to pay. The current precedent to pay likely dates back to the ethically brave organizations who refused to pay. When WannaCryptor (a.k.a. WannaCry) inflicted its malicious payload on the world in 2017, the United Kingdoms National Health Service bore a significant hit on its infrastructure.

REvil victims are refusing to pay after flawed Kaseya ransomware attack

www.bleepingcomputer.com/news/security/revil-victims-are-refusing-to-pay-after-flawed-kaseya-ransomware-attack/ The REvil ransomware gang’s attack on MSPs and their customers last week outwardly should have been successful, yet changes in their typical tactics and procedures have led to few ransom payments. When ransomware gangs conduct an attack, they usually breach a network and take time stealing data and deleting backups before ultimately encrypting the victim’s devices. When a victim is shown proof of stolen data, backups are deleted, and their devices are encrypted, it creates a much stronger incentive for them to pay the ransom to restore their data and prevent the leak of data.

CISA Publishes Malware Analysis Report and Updates Alert on DarkSide Ransomware

In this post I will go over a case involving one such MageCart group.

Hackers Use New Trick to Disable Macro Security Warnings in Malicious Office Files

thehackernews.com/2021/07/hackers-use-new-trick-to-disable-macro.html While it’s a norm for phishing campaigns that distribute weaponized Microsoft Office documents to prompt victims to enable macros in order to trigger the infection chain directly, new findings indicate attackers are using non-malicious documents to disable security warnings prior to executing macro code to infect victims’ computers. In yet another instance of malware authors continue to evolve their techniques to evade detection, researchers from McAfee Labs stumbled upon a novel tactic that “downloads and executes malicious DLLs (ZLoader) without any malicious code present in the initial spammed attachment macro.”

Ransomwhere project wants to create a database of past ransomware payments

therecord.media/ransomwhere-project-wants-to-create-a-database-of-past-ransomware-payments/ A new website launched this week wants to create a crowdfunded, free, and open database of past ransomware payments in the hopes of expanding visibility into the broader picture of the ransomware ecosystem. Named Ransomwhere, the new portal is the personal project of Jack Cable, a Stanford University student and a security researcher for the Krebs Stamos Group. The website allows victims of ransomware attacks or cybersecurity professionals to submit a copy of a ransom note, along with the size of the ransom demand and the Bitcoin address where victims made the payment, which would then be indexed in a public database.

Global Phishing Campaign Targets Energy Sector and its Suppliers

www.intezer.com/blog/research/global-phishing-campaign-targets-energy-sector-and-its-suppliers/ Our research team has found a sophisticated campaign, active for at least one year, targeting large international companies in the energy, oil & gas, and electronics industries. The attack also targets oil & gas suppliers, possibly indicating that this is only the first stage in a wider campaign. In the event of a successful breach, the attacker could use the compromised email account of the receipt to send spear phishing emails to companies that work with the supplier. Thus using the established reputation of the supplier to go after more targeted entities.

Traficom laajentaa Tietoturvamerkin käyttöä puhelimille sitä tuskin myönnetään

www.tivi.fi/uutiset/traficom-laajentaa-tietoturvamerkin-kayttoa-puhelimille-sita-tuskin-myonnetaan/103601a5-8ec3-49ff-b273-764a1c72bda8 Liikenne- ja viestintävirasto Traficomin keväällä teettämän kuluttajatutkimuksen mukaan lähes 80 prosenttia suomalaisista oli tietoisia älylaitteiden tietoturvariskeistä. Vuonna 2019 vastaava osuus oli alle 70 prosenttia. Saman tutkimuksen mukaan älylaitteen tietoturvallisuudesta kertova merkki vaikuttaisi ostopäätökseen 45 prosentilla vastaajista. Traficom lanseerasi vuonna 2019 Tietoturvamerkin, jonka tavoitteena on auttaa kuluttajia tekemään tietoturvallisia ostopäätöksiä. Ensimmäiset laitteet saivat merkinnän vuonna 2020.. Aiemmin Kyberturvallisuuskeskus on itse vastannut merkin vaatimista tietoturvatarkastuksista, mutta nyt myös yritykset voivat tehdä tarkastuksia. Taustalla on halu laajentaa merkittyjen laitteiden saamista kauppoihin ja helpottaa yritysten tuotetarkastusprosessia.

Mikko Hyppönen: Ennen pitkää Suomessakin rysähtää näin järjestäytynyt verkkorikollisuus tehtailee kyberhyökkäyksiä

www.tivi.fi/uutiset/tv/aacc69d6-a01c-4bde-97ab-24f5459595c5 Venäläisen REvilin kiristyshaittaohjelma sulki ruotsalaisen Coopin 800 ruokakauppaa viikoksi. F-Securen Mikko Hyppösen mukaan vastaavaa saatetaan nähdä Suomessakin ennen pitkää. Ihan vain todennäköisyyksiä katsomalla voi sanoa, että ennen pitkää Suomessakin rysähtää. Voidaan henkisesti valmistautua siihen, että tällainen tapaus tulee Suomeen ennemmin tai myöhemmin. Jos ei tänä vuonna tule niin ihmeellistä on, Hyppönen kommentoi Tiville.
