datavergiftiging, of “bronvergiftiging”
De huidige geopolitieke situatie dwingt ons om te anticiperen- en ons voor te bereiden op een breed scala aan cyberrisico’s. Conflicten zijn niet langer beperkt tot de militaire sfeer; ze spelen zich af op meerdere fronten. Tegelijkertijd brengt de toenemende verspreiding van AI nieuwe soorten cyber risico’s met zich mee. De opkomst van AI-gestuurde technologieën en hun afhankelijkheid van online data introduceert een nieuwe bedreiging: data poisoning, of “bronvergiftiging”.
OSINT as a vector for cyber threat intelligence, from indicator collection to attribution
Cyber threat intelligence is the product of an approach to identifying, analyzing and tracking cyber attacks and threats. The aim is to obtain information, particularly technical information, to help organizations make decisions and improve their defense capabilities. This is a “multi-source” approach: the more numerous and complementary the sources exploited, the greater the intelligence potential. Open sources are of course exploited in this context.
Kaspersky Incident Response report 2022
Kaspersky offers various services to organizations that have been targeted by cyberattackers, such as incident response, digital forensics, and malware analysis. In our annual incident response report, we share information about the attacks that we investigated during the reporting period. Data provided in this report comes from our daily interactions with organizations seeking assistance with full-blown incident response or complementary expert services for their internal incident response teams.
Subscription Trojans on Google Play
Every once in a while, someone will come across malicious apps on Google Play that seem harmless at first. Some of the trickiest of these are subscription Trojans, which often go unnoticed until the user finds they have been charged for services they never intended to buy. This kind of malware often finds its way into the official marketplace for Android apps. The Jocker family and the recently discovered Harly family are just two examples of this.
Kaspersky Managed Detection and Response 2022 report
Kaspersky Managed Detection and Response (MDR) is a service for 24/7 monitoring and response to detected incidents based on technologies and expertise of Kaspersky Security Operations Center (SOC) team. MDR allows detecting threats at any stage of the attack – both before anything is compromised and after the attackers have penetrated the company’s infrastructure. This is achieved through preventive security systems and active threat hunting – the essential MDR components.
Tomiris called, they want their Turla malware back
Introduction We introduced Tomiris to the world in September 2021, following our investigation of a DNS-hijack against a government organization in the Commonwealth of Independent States (CIS). Our initial report described links between a Tomiris Golang implant and SUNSHUTTLE (which has been associated to NOBELIUM/APT29/TheDukes) as well as Kazuar (which has been associated to Turla); however, interpreting these connections proved difficult.
Indicators of compromise (IOCs): how we collect and use them
It would hardly be an exaggeration to say that the phrase “indicators of compromise” (or IOCs) can be found in every report published on the Securelist. Usually after the phrase there are MD5 hashes[1], IP addresses and other technical data that should help information security specialists to counter a specific threat. But how exactly can indicators of compromise help them in their everyday work?
Two more malicious Python packages in the PyPI
On August 8, CheckPoint published a report on ten malicious Python packages in the Python Package Index (PyPI), the most popular Python repository among software developers. The malicious packages were intended to steal developers’ personal data and credentials. Following this research, we used our internal automated system for monitoring open-source repositories and discovered two other malicious Python packages in the PyPI.
VileRAT: DeathStalker’s continuous strike at foreign and cryptocurrency exchanges
In late August 2020, we published an overview of DeathStalker’s profile and malicious activities, including their Janicab, Evilnum and PowerSing campaigns (PowerPepper was later documented in 2020). Notably, we exposed why we believe the threat actor may fit a group of mercenaries, offering hack-for-hire services, or acting as an information broker to support competitive and financial intelligence efforts.
Dynamic analysis of firmware components in IoT devices
Among the various offensive security techniques, vulnerability assessment takes priority when it comes to analyzing the security of IoT/IIoT devices. In most cases, such devices are analyzed using the black box testing approach, in which the researcher has virtually no knowledge about the object of research.
The SessionManager IIS backdoor: a possibly overlooked GELSEMIUM artefact
A possibly overlooked GELSEMIUM artefact Following on from our earlier Owowa discovery, we continued to hunt for more backdoors potentially set up as malicious modules within IIS, a popular web server edited by Microsoft. And we didn’t come back empty-handed… In 2021, we noticed a trend among several threat actors for deploying a backdoor within IIS after exploiting one of the ProxyLogon-type vulnerabilities within Microsoft Exchange servers.
Owowa: the add-on that turns your OWA into a credential stealer and remote access panel
While looking for potentially malicious implants that targeted Microsoft Exchange servers, we identified a suspicious binary that had been submitted to a multiscanner service in late 2020. Analyzing the code, we determined that the previously unknown binary is an IIS module, aimed at stealing credentials and enabling remote command execution from OWA. We named the malicious module ‘Owowa’, and identified several compromised servers located in Asia.
Tomiris backdoor and its connection to Sunshuttle and Kazuar
Background In December 2020, news of the SolarWinds incident took the world by storm. While supply-chain attacks were already a documented attack vector leveraged by a number of APT actors, this specific campaign stood out due to the extreme carefulness of the attackers and the high-profile nature of their victims. It is believed that when FireEye discovered the first traces of the campaign, the threat actor (DarkHalo aka Nobelium) had already been working on it for over a year.
Attaques APT31 - réaction de Kaspersky
Attaques APT31 - réaction de Kaspersky juillet 2021 par Pierre Delcher, Senior Security Researcher au sein de l’équipe du GReAT de Kaspersky L’ANSSI (Agence nationale de la sécurité des systèmes d’information) a récemment alerté sur une campagne de cyberattaques menée par le groupe APT31 à l’encontre de routeurs en France. Les routeurs seraient utilisés en tant que relais d’anonymisation afin de réaliser des actions de reconnaissance et malveillantes.
Researchers Call For A Determined Path To Cybersecurity As We Are En Route To Lose The Fight Against Cybercrime
Pierre Delcher, senior security researcher at Kaspersky’s Global Research and Analysis Team (GReAT) on the issues in battling cybercrime and a plan of what we should do to finally start winning this fight Cybersecurity researchers, governmental bodies, independent threat hunters, private cybersec organisations – we all do our jobs not in the least to contribute to a broader mission of building a safer world. Yet, somehow, we are failing. Cyberattacks numbers keep skyrocketing every year.
What did DeathStalker hide between two ferns?
DeathStalker is a threat actor that’s been active since at least 2012, and we exposed most of their past activities in a previous article, as well as during a GREAT Ideas conference in August 2020. The actor drew our attention in 2018 because of distinctive attack characteristics that didn’t fit in with the usual cybercrime or state-sponsored activities, leading us to believe DeathStalker is a hack-for-hire group..
IAmTheKing and the SlothfulMedia malware family
On October 1, 2020, the DHS CISA agency released information about a malware family called SlothfulMedia, which they attribute to a sophisticated threat actor. We have been tracking this set of activity through our private reporting service, and we would like to provide the community with additional context. In June 2018, we published the first report on a new cluster of activities that we named IAmTheKing, based on malware strings discovered in a malware sample from an unknown family.
Lazarus on the hunt for big game
We may only be six months in, but there’s little doubt that 2020 will go down in history as a rather unpleasant year. In the field of cybersecurity, the collective hurt mostly crystallized around the increasing prevalence of targeted ransomware attacks. By investigating a number of these incidents and through discussions with some of our trusted industry partners, we feel that we now have a good grasp on how the ransomware ecosystem is structured.
Holy water: ongoing targeted water-holing attack in Asia
On December 4, 2019, we discovered watering hole websites that were compromised to selectively trigger a drive-by download attack with fake Adobe Flash update warnings. This campaign has been active since at least May 2019, and targets an Asian religious and ethnic group.
Lifting the veil on DeathStalker, a mercenary triumvirate
State-sponsored threat actors and sophisticated attacks are often in the spotlight. Indeed, their innovative techniques, advanced malware platforms and 0-day exploit chains capture our collective imagination. Yet these groups still aren’t likely to be a part of the risk model at most companies, nor should they be. Businesses today are faced with an array of much more immediate threats, from ransomware and customer information leaks, to competitors engaging in unethical business practices.
The leap of a Cycldek-related threat actor
Introduction In the nebula of Chinese-speaking threat actors, it is quite common to see tools and methodologies being shared. One such example of this is the infamous “DLL side-loading triad”: a legitimate executable, a malicious DLL to be sideloaded by it, and an encoded payload, generally dropped from a self-extracting archive. Initially considered to be the signature of LuckyMouse, we observed other groups starting to use similar “triads” such as HoneyMyte.
BlackOasis APT and new targeted attacks leveraging zero-day exploit
More information about BlackOasis APT is available to customers of Kaspersky Intelligence Reporting Service. Contact: intelreports@kaspersky.com Introduction Kaspersky Lab has always worked closely with vendors to protect users. As soon as we find new vulnerabilities we immediately inform the vendor in a responsible manner and provide all the details required for a fix.
