Olympus Suffers another Cyberattack

The Japanese tech giant, Olympus, announced that its IT systems in the US, Canada, and Latin America had suffered a cybersecurity incident. Details of the attack are thin on the ground, but the attack follows another incident that occurred in September 2021. The first attack was announced on September 11, which according to the company affected the IT systems for Europe, the MIddle-East, and Africa. Again details of the attack were sparse but according to Bleeping Computer, the attack involved the now-infamous BlackMatter ransomware.

Security Researchers Discover Operation GhostShell

According to a recently published blog by Cybereason Nocturnus, researchers for the security firm have discovered a cyber espionage campaign making use of previously undiscovered malware. Researchers have, further, attributed the new espionage campaign to an also previously undisclosed threat group they have codenamed MalKamak. The group is currently targeting organizations in the aerospace and telecoms sectors.

Tomiris Backdoor Tentatively Linked to DarkHalo

Kaspersky Labs just recently published a report detailing a link between the Tomiris backdoor and the threat actors behind the SolarWinds attack that occurred towards the end of 2020. In summary, the backdoor closely resembles another piece of malware deployed by DarkHalo, SunShuttle, as well as similar tactics used in finding targets and deploying malware.

Android Users have Two Trojans to Worry About

This week has seen the announcement of two separate campaigns infecting Android users with some form trojan malware. The first incident involves the discovery of a new trojan, called GriftHorse, while the second trojan distribution campaign involves an offshoot of the infamous Cerberus banking trojan. This latest Cerberus-based trojan has been called ERMAC by researchers.

Researchers Discover a Ransomware Mystery

Security firm eSentire published an article detailing an odd ransomware incident. In summary, the incident is odd as it used advanced techniques to gain initial access and compromise the target’s network. However, the ransomware dropped, Hello, is regarded as fairly unsophisticated. This provided researchers with a few head-scratching moments.

The victim in the instance observed was a testing company that evaluates hundreds of products from around the globe. This implies that during testing the company has access to a ton of intellectual property, making the company a high-profile target for attackers. The attack was also determined by researchers to be a hands-on-keyboard attack.

CISA helps draw the Curtain on Conti Ransomware Operations

The Cybersecurity and Infrastructure Security Agency (CISA) recently published an advisory regarding the Conti ransomware. The advisory provides a comprehensive analysis of techniques used by the ransomware gang in the past and present. The advisory also noted that the Federal Bureau of Investigation (FBI) has observed more than 400 incidents involving ransomware internationally and in the US. The advisory also includes mitigation strategies to protect against falling victim to a Conti attack, measures that CISA, the FBI, and the NSA have adopted to secure their infrastructure.

Ransomware Operators Target Developers via Microsoft Vulnerability

According to research published by Microsoft, a new threat actor has been attacking developers by exploiting a vulnerability in MSHTML, tracked as CVE-2021-40444, which has been patched. Developers familiar with or use MSHTML should ensure that the patch has been installed. Microsoft describes that an attacker could “craft a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine.

New Investigations Shed Light on the Juniper Attacks

It was nearly Christmas 2015 when Juniper released a statement warning customers that it had discovered unauthorized code that allowed hackers to decipher encrypted communications and gain high-level access to customers’ machines that used a popular product developed by the company. The exact wording issued by Juniper stated,

Mēris Botnet Breaking DDoS Records

At the start of this year, researchers looked back on 2020 and discovered it was a boom year for DDoS attacks. Now, Russian Internet giant Yandex is battling the biggest DDoS attack on record and a new Botnet may be the infrastructure powering this record-breaking attack.

Giving the attack method its full name of Distributed Denial of Service (DDoS), the attack involves attempts to maliciously disrupt the normal traffic of a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. This can be done through the use of botnets, devices infected with specific malware that allows a hacker control over the device and can send HTTP requests via a device, typically Internet of Things devices and routers.

Researchers Report Sodinokibi Lives Again

Also known as REvil, and sometimes referred to as the Crown Prince of Ransomware, Sodinokibi has long been the thorn in the side of large enterprises and a headline maker. This year alone those behind the ransomware were responsible for both the JBS incident and the Kaseya incident. The latter prompted direct statements of intent by both US President Joe Biden and US law enforcement agencies. This in turn was the likely motivator for the gang to take a holiday.

The bad news is it appears the gang is back in action after taking a summer holiday. When websites and infrastructure known to be used by the ransomware gang were taken offline, many in the InfoSec hoped that the group has thrown in the towel. Lawrence Abraham, of Bleeping Computer, took to Twitter to report that the group's leak site, Happy Blog, was back online with activity dating back to July.

Microsoft warns of Sneaky Phishing Tactic

Microsoft security researchers have recently published an article detailing a widespread phishing campaign looking to steal credentials by abusing redirector links. At first, the potential victim is baited by impersonations of well-known productivity tools. They are then redirected to multiple sites which include a CAPTCHA verification page before taking the victim to a fake login page.

Using redirection links has long been a favored technique of hackers, but it is also used by legitimate businesses even if it irritates some customers. Often redirects are used in emails sent by sales and marketing teams to lead customers to a desired landing web page and track click rates and other metrics.

FIN8 seen using new Backdoor called Sardonic

FIN8 is a purely financially motivated cybercrime organization and since 2016, the group has successfully operated by targeting retail, restaurant, hospitality, healthcare, and entertainment industries. This is done to primarily steal payment information from Point of Sale (POS) devices those industries typically rely on to process payments from customers. These tactics were used towards the end of 2019 when Visa warned that the group was compromising POS devices used by fuel stations in North America. FIN8 attack campaigns are conducted sporadically but never fail to make an impact leaving victims questioning how best to shore up their defenses.

LockBit 2.0 has Chile in its Sights

The LockBit ransomware gang has been operational since 2019. In June 2021, the gang deployed a newer version of the ransomware, dubbed LockBit 2.0 by its developers, was seen by researchers making a stir on underground forums. Now, a report published by Trend Micro details how the new version has been deployed in recent campaigns starting in July of this year.

The campaigns targeted organizations in Chile, Italy, Taiwan, and the U.K making use of the newer version.

Conti Ransomware’s Secret Backdoor Discovered

Getting to peek behind the curtains of a ransomware operation is rare. Figuring out the inner workings of modern ransomware-as-a-service operations is an investigation that can take hours upon hours to glean the smallest bits of information. Sometimes discoveries are made that pull the curtain back a little further. Recent blog posts by Vitali Kremez’s Advanced Intelligence have helped expose large sections of the Conti gang’s operations and tactics.

One such blog post revealed how affiliates gain persistence on a victim’s network and avoid detection by security applications.
