Intentionally not drawing attention. 17.10.2020

Bitdefender researchers recently uncovered a sophisticated APT-style attack targeting an international architectural and video production company. The attack shows signs of industrial espionage, similar to another of Bitdefender’s recent investigations of the StrongPity APT group. The real-estate industry is highly competitive, and information exfiltrated by APT mercenary group can give negotiatio...

It's still possible to find ways to break out. 10.10.2020

Containers offer speed, performance, and portability, but do they actually contain? While they try their best, the shared kernel is a disturbing attack surface: a mere kernel vulnerability may allow containerized processes to escape and compromise the host. This issue prompted a new wave of sandboxing tools that use either unikernels, lightweight VMs or userspace-kernels to separate the host OS fr...

Smaug: Ransomware-as-a-service drag(s)on. 03.10.2020

Threat actors and cybercriminals that don’t have the ability to develop their own ransomware for malicious campaigns can turn to the Smaug Ransomware as a Service (RaaS) offering, which is available via a Dark Web Onion site. At least two threat actors are operating the site, providing ransomware that can be used to target Windows, macOS, and Linux machines. The site is built with ease of use in m...

What came first, the Golden Chickens or more_eggs? 26.09.2020

Throughout March and April, QuoIntelligence (QuoINT) observed four attacks (i.e. sightings) utilizing various tools from the Golden Chickens (GC) Malware-as-a-Service (MaaS) portfolio – they recently declassified their findings, after first notifying their clients. Further, during their analysis of the sightings, QuoIntelligence confirmed the GC MaaS Operator, Badbullzvenom, released improved vari...

Election 2020: What to expect when we are electing. 19.09.2020

After the 2016 General Election, the talk was all around foreign meddling. Rumors swirled that some votes may have been changed or influenced by state-sponsored actors. Sanctions and accusations followed. Four years later, is the U.S. any more prepared to protect the results of its largest elections? More than you may realize. Talos researchers take a deep dive into election security after spendin...

Leveraging legitimate tools. 12.09.2020

Researchers at Symantec spotted a Sodinokibi targeted ransomware campaign in which the attackers are also scanning the networks of some victims for credit card or point of sale (PoS) software. It is not clear if the attackers are targeting this software for encryption or because they want to scrape this information as a way to make even more money from this attack. Joining us in this week's Resear...

Going after the most valuable data. 05.09.2020

A look at the realities of ransomware from Sophos, including an industry-first detailed look at new detection evasion techniques in WastedLocker ransomware attacks that leverage the Windows Cache Manager and memory-mapped I/O to encrypt files. A complementary article examines the evasion-centric arms race of ransomware, providing a months-long review of how cybercriminals have been escalating and...

They fooled a lot of people. 29.08.2020

Docker containers have been gaining popularity over the past few years as an effective way of packaging software applications. Docker Hub provides a strong community-based model for users and companies to share their software applications. This is also attracting the attention of malicious actors intending to make money by cryptojacking within Docker containers and using Docker Hub to distribute t...

Using global events as lures. 22.08.2020

The goal of malicious activity is to compromise the system to install some unauthorized software. Increasingly that goal is tied to one thing: the user. Over the past several years, we as an industry improved exploit mitigation and the value of working exploits has increased accordingly. Together, these changes have had an impact on the threat landscape. We still see large amounts of active exploi...

Waiting for their victims. 15.08.2020

Bitdefender researchers have recently found the APT group StrongPity has been targeting victims in Turkey and Syria. Using watering hole tactics to selectively infect victims and deploying a three-tier C&C infrastructure to thwart forensic investigations, the APT group leveraged Trojanized popular tools, such as archivers, file recovery applications, remote connections applications, utilities, and...

Like anything these days, you have to disinfect it first. 08.08.2020

“Cyberbunker” refers to a criminal group that operated a “bulletproof” hosting facility out of an actual military bunker. “Bullet Proof” hosting usually refers to hosting locations in countries with little or corrupt law enforcement, making shutting down criminal activity difficult. Cyberbunker, which is also known as “ZYZtm” and “Calibour”, was a bit different in that it actually operated out of...

Detecting Twitter bots in real time. 01.08.2020

NortonLifeLock Research Group (NRG) released a prototype browser extension called BotSight that leverages machine learning to detect Twitter bots in real-time. The tool is intended to help users understand the prevalence of bots and disinformation campaigns within their Twitter feeds, particularly with the increase in disinformation of COVID-19. Joining us on this week's Research Saturday to discu...

It was only a matter of time. 25.07.2020

On April 29, 2020, the Salt management framework, authored by the IT automation company SaltStack, received a patch concerning two CVEs; CVE-2020-11651, an authentication bypass vulnerability, and CVE-2020-11652, a directory-traversal vulnerability. On April 30, 2020, researchers at F-Secure disclosed their vulnerability findings to the public, with an urgent warning for Salt users - patch now. Be...

Every time we get smarter, the bad guy changes something. 18.07.2020

Researchers at Symantec identified and alerted customers to a string of attacks against U.S. companies by attackers attempting to deploy the WastedLocker ransomware (Ransom. WastedLocker) on their networks. The end goal of these attacks is to cripple the victim’s IT infrastructure by encrypting most of their computers and servers in order to demand a multimillion dollar ransom. At least 31 Symante...

Are you running what you think you're running? 11.07.2020

Built into virtually every hardware device, firmware is lower-level software that is programmed to ensure that hardware functions properly. As software security has been significantly hardened over the past two decades, hackers have responded by moving down the stack to focus on firmware entry points. Firmware offers a target that basic security controls can’t access or scan as easily as software,...

Enter the RAT. 27.06.2020

A new report examines how five related APT groups operating in the interest of the Chinese government have systematically targeted Linux servers, Windows systems and Android mobile devices while remaining undetected for nearly a decade. The report comes on the heels of the U.S. Department of Justice announcing several high-profile indictments from over 1,000 open FBI investigations into economic e...

Click here to update your webhook. 20.06.2020

Slack is a cloud-based messaging platform that is commonly used in workplace communications. Slack Incoming Webhooks allow you to post messages from your applications to Slack. Generally, Slack webhooks are considered a low risk integration. A deeper dive into webhooks shows that this is not entirely accurate.  Joining us in this week's Research Saturday is Ashley Graves from AT&T Cybersecurity's...

The value of the why and the who. 13.06.2020

Proactive, efficient threat mitigation and risk management require understanding adversaries’ fundamental thought processes, not just their tools and methods. Cyber threat intelligence analysts combed through 15 years (2004 to 2019) of public sources that have documented the activities of one prolific threat actor, Russia’s military intelligence agency, the GRU. Analysis shows that the timing, tar...

Due diligence cannot be done as a one-off. 06.06.2020

Earlier this year, a Virgin Media database containing the personal details of 900,000 people was discovered to be unsecured and accessible online for 10 months. The breach was discovered by researchers at the security firm TurgenSec. This breach had major implications under GDPR.  Joining us in this week's Research Saturday are George Punter and Peter Hansen from TurgenSec to talk about the discov...

Twofold snooping venture. 30.05.2020

Working with many different honeypot implementations, a security researcher did an experiment expanding on that setting up a simple docker image with SSH, running a guessable root password. The catch? What happened in the next 24 hours was unexpected.

Naming and shaming is the worst thing we can do. 23.05.2020

In December 2019, the GOLD VILLAGE threat group that operates the Maze ransomware created a public website to name and shame victims. The threat actors used the website to dump data they exfiltrated from victims' networks before they deployed the ransomware. Secureworks Counter Threat Unit (CTU) researchers have observed several ransomware operators following suit. Joining us in this week's Resear...

The U.S. campaign trail is actually quite secure. 09.05.2020

Multiple media reports have indicated that the United States’ (U.S.) 2020 general election could be targeted by foreign and domestic actors after the successful cyber and misinformation attacks during the 2016 general election. The responsibility of secure and ethical online campaigning has become a central issue in the 2020 election. In some cases, it has become part of candidate platforms. Joini...

Fingerprint authentication is not completely secure. 02.05.2020

Passwords are the traditional authentication methods for computers and networks. But passwords can be stolen. Biometric authentication seems the perfect solution for that problem. Our guest today is Craig Williams, director of Talos outreach at Cisco. He'll be discussing and providing insights into their report which shows that fingerprints are good enough to protect the average person's privacy i...

Contact tracing as COVID-19 aid. 25.04.2020

Successful containment of the Coronavirus pandemic rests on the ability to quickly and reliably identify those who have been in close proximity to a contagious individual. Mayank Varia from Boston University describes how his team suggests an approach based on using short-range communication mechanisms, like Bluetooth, that are available in all modern cell phones. The research can be found here: A...
