What Has Changed Since the 2017 WannaCry Ransomware Attack?
securityintelligence.com/articles/what-has-changed-since-wannacry-ransomware-attack/ The cybersecurity world is still feeling the effects of the 2017 WannaCry ransomware attack today. While the majority of the damage occurred in the weeks after May 12, 2017, WannaCry ransomware attacks actually increased 53% from January 2021 to March 2021. While researching my in-depth article WannaCry: How the Widespread Ransomware Changed Cybersecurity, I learned that WannaCry attacks are still found today. Even so, I was surprised that it is still such an active issue. So, what has happened since then? What are these attackers doing today? How have organizations responded to these threats? And will an attack like this happen again?
Too Log; Didn’t Read Unknown Actor Using CLFS Log Files for Stealth
www.fireeye.com/blog/threat-research/2021/09/unknown-actor-using-clfs-log-files-for-stealth.html The Mandiant Advanced Practices team recently discovered a new malware family we have named PRIVATELOG and its installer, STASHLOG. In this post, we will share a novel and especially interesting technique the samples use to hide data, along with detailed analysis of both files that was performed with the support of FLARE analysts. We will also share sample detection rules, and hunting . Mandiant has yet to observe PRIVATELOG or STASHLOG in any customer environments or to recover any second-stage payloads launched by PRIVATELOG. This may indicate malware that is still in development, the work of a researcher, or targeted activity.
Flaw in the Quebec vaccine passport: analysis
www.welivesecurity.com/2021/08/31/flaw-quebec-vaccine-passport-vaxicode-verif-analysis/ The launch of the mobile applications allowing the storage and verification of the vaccination passport by the Quebec government (VaxiCode and VaxiCode Verif) has caused a lot of ink to flow last week. It is with good reason; the VaxiCode Verif app will be used by all non-essential service merchants as of September 1, 2021. Like many other experts, I analyzed the contents of the QR code as soon as I received it during my first vaccination last May. Last week, I also analyzed the two applications established by the Quebec government and developed by Akinox.

BEC Scammers Seek Native English Speakers on Underground
threatpost.com/bec-scammers-native-english-speakers/169092/ Looking for work? Speak fluent English? Capable of convincingly portraying a professional as in, somebody a highly ranked corporate leader would talk to?.

Its easy work, they promise: Theyll do the heavy lifting of getting unauthorized access to Microsoft Office 365 domains. All that their English-speaking conspirators need to do is sound convincing.
Half of businesses can’t spot these signs of insider cybersecurity threats
www.zdnet.com/article/half-of-businesses-cant-spot-these-signs-of-insider-cybersecurity-threats/ Most businesses are struggling to identify and detect early indicators that could suggest an insider is plotting to steal data or carry out other cyberattacks. Research by security think tank the Ponemon Institute and cybersecurity company DTEX Systems suggests that over half of companies find it impossible or very difficult to prevent insider attacks. These businesses are missing indicators that something might be wrong. Those include unusual amounts of files being opened, attempts to use USB devices, staff purposefully circumventing security controls, masking their online activities, or moving and saving files to unusual locations. All these and more might suggest that a user is planning malicious activity, including the theft of company data.
Etsintäkuulutettu ammattirikollinen murtautui F-Securen pääkonttoriin sisään pääsi häiritsevän helposti
www.tivi.fi/uutiset/tv/420aeddf-e34a-4c24-a0fe-7ad0866f5e0d Harvemmin ison yrityksen pääkonttorille onnistutaan murtautumaan, ja vielä harvemmin niin, ettei murtautuja vie mennessään yhtään mitään. Näin kuitenkin kävi Suomessa eräänä salaperäisenä yönä. Asialla oli tunnettu ammattirikollinen. Teknisen tietoturvakonsultoinnin johtaja Tomi Tuominen on kirjoittanut F-Securen sivuille lähes kaunokirjallisen blogitekstin tapauksesta. Se nousi tänä kesänä puheenaiheeksi it-alalla, koska konttorilla oli F-Securen mukaan siivouskomeroksi luultu, kansallisen infrastruktuurin kannalta kriittinen tietoliikennehuone. F-Securen teksti herätti keskustelua it-alalla erityisesti tietoliikennehuoneen takia. Kysyimme Liikenne- ja viestintäviraston Kyberturvallisuuskeskuksen asiantuntijalta Tapio Sokuralta, millaisia tavoitteita tietoliikennehuoneisiin tähtäävillä hyökkääjillä voi olla. Sokura kommentoi asiaa yleisellä tasolla.
