September was a record month for ransomware attacks in 2023

-

 


Ransomware activity in September reached unprecedented levels following a relative lull in August that was still way above regular standards for summer months.

According to NCC Group data, ransomware groups launched 514 attacks in September. This surpasses March 2023 activity, which counted 459 attacks, and was heavily skewed by Clop's Fortra GoAnywhere data theft attacks.

Clop had virtually no activity in September, which may be a sign the sophisticated ransomware gang is preparing for its next big attack. 

However, the record was achieved by other threat groups, led by LockBit 3.0 (79 attacks), LostTrust (53), and BlackCat (47).

LostTrust is a new threat actor in the list, making a dynamic entrance straight to second place.

Believed to be a rebrand of MetaEncryptor due to significant code overlaps, LostTrust has already encrypted the networks of many organizations, some of whom experienced data leaks, too.

RansomedVC, a newcomer in extortion attacks employing GDPR reporting threats, is in NCC's fourth place with 44 attacks. However, it should be noted that some of the attacks claimed by Ransomed were later found to be exaggerated.

This means that roughly one out of five attacks in September came from a new ransomware operation, highlighting their aggressiveness and capability for scale.

In terms of targeted regions, North America took the lion's share with 50%, Europe followed with 30%, and Asia was third with 9%.

The most targeted sectors were 'industrials' (construction, engineering, commercial services) with 169 attacks, 'consumer cyclicals' (retail, media, hotels) with 94, technology (software and IT services, networking, telecommunications) with 52, and healthcare with 38.

2023 on a record trajectory

NCC's report highlights that from January 2023 until September 2023, it has recorded nearly 3,500 attacks, and it's now likely that the final figure will be close to 4,000 by the end of the year.

Another report by Chainalysis from earlier this year predicted 2023 to be a record-breaking year for ransomware payments based on projected data.

Despite the continuous efforts by law enforcement to curb the problem, which has matured, ransomware remains a shape-shifting threat that bombards organizations with ever-improving initial access methods and increasingly covert tactics and payloads.

Update 10/25: Article updated to perform factual corrections regarding March 2023 attacks.

  The European Union Agency for Cybersecurity (ENISA) has signed a Working Arrangement with the Cybersecurity and Infrastructure Security Agency (CISA) of the US, in the areas of capacity-building, best practices exchange and boosting situational awareness. Geopolitics have shaped the cyber threat landscape, bringing like-minded partners closer together in the wake of common cyber challenges and advances in digital technologies. Today at the EU-US Cyber Dialogue, ENISA and CISA announced the signing of their Working Arrangement as an important milestone in the overall cooperation between the United States and the European Union in the field of cybersecurity, also following the Joint Statement of European Commissioner Thierry Breton and U.S. Secretary for Homeland Security Alejandro Mayorkas of January 2023. ENISA’s International Strategy directs the Agency to be selective in engaging with international partners and to limit its overall approach in international cooperation to those...

In January 2024, cybersecurity faced a remarkable surge in threats, with a focus on exploiting vulnerabilities in technologies from leading vendors. This spike in cyber attacks highlighted the urgent necessity for robust security posture and swift responses to mitigate these vulnerabilities.  Below is an in-depth analysis of the most critical vulnerabilities targeted during January. CVE-2023-46805 and CVE-2024-21887:   CISA Warns Against Ivanti Zero-Day Vulnerabilities On January 19, 2024, the Cybersecurity and Infrastructure Security Agency (CISA) issued an alert regarding two critical zero-day vulnerabilities discovered in Ivanti products:  CVE-2023-46805 and  CVE-2024-21887.  Assigned CVSS scores of 8.2 (High) and 9.1 (Critical), these vulnerabilities underscore a significant risk to cybersecurity, marked by their capability for arbitrary command execution. This prompted an emergency directive for immediate mitigation within federal agencies, highlighting the...

SmartScreen Vulnerability: CVE-2024-21412 Facts and Fixes

-
Image
On Feb. 13, 2024, Microsoft issued a  patch  for CVE-2024-21412, a  Microsoft Defender SmartScreen  vulnerability revolving around internet shortcuts. Previously, we discovered that an advanced persistent threat (APT) group we track under the name Water Hydra has been exploiting CVE-2024-21412 in a sophisticated campaign targeting financial market traders, allowing the group to bypass Microsoft Defender SmartScreen and infect its victims with the DarkMe remote access trojan (RAT). Threat actors are constantly finding new ways of identifying and exploiting gaps to bypass security measures. We found that the bypass of CVE-2023-36025 (a previously patched SmartScreen vulnerability) led to the discovery and exploitation of CVE-2024-21412. This highlights how threat actors can circumvent patches by identifying new vectors of attack around a patched software component. It is important that organizations are able to identify and mitigate vulnerabilities, especiall...
