Cybersecurity firm Stormshield hacked. Data (including source code) stolen

grahamcluley.com/cybersecurity-firm-stormshield-hacked-data-including-source-code-stolen/ French cybersecurity firm Stormshield has revealed that it has suffered a security breach, and hackers have accessed sensitive information. The company, which is a major provider to the French government, says that a hacker managed to steal data after gaining access to a portal used by customers and partners, potentially accessing support tickets and communications with staff. While investigating the security breach, Stormshield also discovered that some of the source code for the Stormshield Network Security (SNS) firewall was also stolen. This raises the spectre of a malicious attacker either uncovering security holes in the firewall that might be exploited in later attacks, or the creation of malicious updates. also: www.stormshield.com/security-incident-stormshield/

Toimitusjohtajapetoksilla vietiin lähes 7 miljoonaa euroa *[Tilaajille]

Poliisi kirjasi niistä yhteensä 414 rikosilmoitusta. Poliisihallituksen poliisitarkastaja Tuomas Pöyhönen esittää, että tietoturvasta tulisi yksi osa-alue vaikkapa yrittäjäkursseille. “Liian usein tietoturvan merkitys ymmärretään vasta sitten kun vahinko on jo tapahtunut”, Pöyhönen sanoo.

Blockchain Analysis Shows Connections Between Four of 2020’s Biggest Ransomware Strains

blog.chainalysis.com/reports/ransomware-connections-maze-egregor-suncrypt-doppelpaymer As we’ve covered on our blog, there may be fewer cybercriminals responsible for ransomware attacks than one would initially think given the number of individual attacks, distinct strains, and amount stolen from victims. Cybersecurity researchers point out that many RaaS affiliates carrying out attacks switch between different strains, and many believe that seemingly distinct strains are actually controlled by the same people. Using blockchain analysis, we’ll investigate potential connections between four of 2020’s most prominent ransomware strains: Maze, Egregor, SunCrypt, and Doppelpaymer.

MTR casebook: Uncovering a backdoor implant in a SolarWinds Orion server

news.sophos.com/en-us/2021/02/03/mtr-casebook-uncovering-a-backdoor-implant-in-a-solarwinds-orion-server/ A real-world story from the Sophos Managed Threat Response team. Given the recent supply chain attack on SolarWinds, this attack is certainly of note. However, we could not identify concrete evidence that the two are connected. The C2s, web shell, and DLL used in this attack are not ones we have observed before, outside of this single incident, nor have we observed them used since.

Connecting the dots inside the Italian APT Landscape

yoroi.company/research/connecting-the-dots-inside-the-italian-apt-landscape/ The news of the hack of one of the major strategic Italian companies circulated in the first half of December 2020 shocked a huge part of the national security community: Leonardo SpA (formerly Finmeccanica) runs critical services and projects directly related to the Italian defense industry and military corps. On 5th December 2020, the Italian police (CNAIPIC) published a press statement revealing the Aerostructures and Aircraft division has been hacked for a long time. The malicious APT presence was dated back to 2015 and lasted for about two years inside the Leonardo division. We have been looking at this case since December 2020 and tracked this new actor as TH-261. But in the initial weeks of 2021 we noticed something unattended: a set of similarities on recent ongoing attacks made us really suspicious about the nature and evolution of this threat.

Abusing Google Chrome extension syncing for data exfiltration and C&C

isc.sans.edu/forums/diary/Abusing+Google+Chrome+extension+syncing+for+data+exfiltration+and+CC/27066/ I had a pleasure (or not) of working on another incident where, among other things, attackers were using a pretty novel way of exfiltrating data and using that channel for C&C communication. Some of the methods observed in analyzed code were pretty scary from a defender’s point of view, as you will see further below in this diary.

Major Vulnerabilities discovered and patched in Realtek RTL8195A Wi-Fi Module

www.vdoo.com/blog/realtek-rtl8195a-vulnerabilities-discovered/ In a recent supply chain security assessment, Vdoo has analyzed multiple networking devices for security vulnerabilities and exposures. During the analysis we have discovered and responsibly disclosed six major vulnerabilities in Realtek’s RTL8195A Wi-Fi module that these devices were based on. An attacker that exploits the discovered vulnerabilities can gain remote root access to the Wi-Fi module, and from there very possibly hop to the application processor as well (as the attacker has complete control of the device’s wireless communications). The RTL8195 module is an extremely compact, low-power Wi-Fi module targeted at embedded devices. It has supported software from major vendors such as ARM, Samsung, Google, Amazon and more. For example, according to AWS it is used in a myriad of industries.
