In February 2022, Microsoft disabled VBA macros on documents due to their frequent use as a malware distribution method. This move prompted malware authors to seek out new ways to distribute their payloads, resulting in an increase in the use of other infection vectors, such as password-encrypted zip files and ISO files.
The Cybersecurity and Infrastructure Security Agency (CISA) shared the findings of an investigation by numerous cybersecurity agencies worldwide on May 9th, exposing the malicious cyberespionage operations carried out by the Russian FSB utilizing the “Snake” malware. The US-CERT Alert (AA23-129A) Hunting Russian Intelligence “Snake” Malware provided information about this investigation and takedown (along with attacker TTPs and IOCs).
Kroll Cyber Threat Intelligence analysts have identified a new strain of ransomware, named CACTUS, targeting large commercial entities since March 2023. The name “CACTUS” is derived from the filename provided within the ransom note, cAcTuS.readme.txt, and the self-declared name within the ransom note itself. Encrypted files are appended with.cts1, although Kroll notes the number at the end of the extension has been observed to vary across incidents and victims.
New data shows a resurgence in successful ransomware attacks with organizations in specific industries, countries and revenue bands being the target. While every organization should always operate under the premise that they may be a ransomware target on any given day, it’s always good to see industry trends to paint a picture of where cybercriminals are currently focusing their efforts.
Unfortunately ransomware attacks have taken another victim. The City of Dallas recently confirmed that their police department suffered a ransomware attack. This attack shutdown essential services along with some 911 dispatch systems. This was announced in a statement by the city in a press release. "Wednesday morning, the City’s security monitoring tools notified our Security Operations Center (SOC) that a likely ransomware attack had been launched within our environment.
The City of Dallas, Texas, is the ninth largest in the United States currently, with a population of more than 2.6 million people.

The attack interfered with policy response time, 911 services, the police website, the city's court system, and more. With such significant interference occurring in the city's system of government, it's a serious issue for everyone in Dallas.
Software developers build approximately 80% of software applications using open-source code, which opens up a world of opportunity for today’s threat actors. Code package repositories such as npm and RubyGems allow anyone to store or publish packages, and unfortunately that can include packages containing malware. These are known as malicious packages — the malware of the software supply chain. As the name implies, a malicious package is software that is created with malicious intent.
Recently, a new trend has emerged in the world of ransomware: intermittent encryption, the partial encryption of targeted files. Many ransomware groups, such as BlackCat and Play, have adopted this approach. However, intermittent encryption is flawed. In this blog post, I will introduce White Phoenix, a tool my team built that takes advantage of the fact that those files aren’t entirely encrypted and can, in the right circumstances, salvage some content from the unencrypted parts of the files.
560,000 new pieces of malware are detected daily and over 1 billion malware programs exist currently.
