Cybercriminals appear to be losing interest in the Cobalt Strike penetration testing suite for their evil deeds. Threat actors have found alternatives in the open-source, cross-platform kit, Sliver. Healthcare and education sectors are once again under increasing threat from a new ransomware family, dubbed Agenda by researchers. Its ransom amount ranges between $50,000 and $800,000. It is suspected that threat actors behind Agenda might be offering ransomware services to affiliates outside their group.

Besides, the CISA warned organizations and agencies to patch a critical ICS-based RCE vulnerability in one of Delta Electronics products used for designing and programming HMIs. Also, this product has reached EOL; it is advised to switch to supported software.

Hackers move on from Cobalt Strike

Several state-sponsored groups and cybercrime gangs are hopping on to the Go-based Sliver security testing tool made by the cybersecurity company BishopFox, instead of using Cobalt Strike. Two threat groups, DEV-0237 and APT29 were observed using the Sliver tool. The former attempted to drop various ransomware payloads, such as Ryuk, Hive, Conti, and BlackCat, via malware including TrickBot and BazarLoader.

Top Vulnerabilities Reported in the Last 24 Hours

Delta Electronics’ bug in CISA’s book

The CISA added 10 security bugs to its Known Exploited Vulnerabilities Catalog, including a high-severity RCE flaw in the Delta Electronics DOPSoft 2 software. Tracked as CVE-2021-38406, it is an out-of-bounds write issue that can be exploited by making the targeted user open a malicious file. There is no data on the exploitation of the bug in the wild.

CERT-In points out flaw

A path traversal vulnerability in RarLab’s UnRAR may impact Linux and Unix systems, warned CERT-In. The bugs can be exploited to execute arbitrary code on the targeted systems. Additionally, a critical vulnerability in the Realtek software development kit was also highlighted. The zero-click bug exists due to improper bounds checking by the SIP ALG function. Users are requested to update their software to the patched version.

A newly surfaced threat actor, UAT-5918, has been quietly embedding itself into Taiwan’s critical infrastructure since 2023. With a focus on information theft, the group has been targeting multiple sectors using a mix of off-the-shelf tools and stealthy web shells. The threat actor also boasts of an extensive toolkit. Meanwhile, the Medusa ransomware operation is refining its ability to bypass defenses using a malicious driver disguised as a legitimate security component. Dubbed ABYSSWORKER, the driver is signed with compromised certificates. Once deployed, it disables anti-malware tools and clears the path for ransomware delivery through a loader. On the plugin front, a critical vulnerability in WP Ghost has put thousands of WordPress sites at risk. If certain non-default settings are enabled, the bug can be used to load arbitrary files - opening the door to remote code execution. Though a patch has been issued in version 5.4.02, the exposure window combined with the plugin’s wide install base makes this a notable concern for site admins still lagging on updates.

Cybercriminals don’t just break in; they move in and redecorate. The DollyWay malware campaign, active since 2016, has now compromised over 20,000 WordPress sites, according to GoDaddy. By February 2025, it was redirecting 10 million users each month to scam sites. Originally a ransomware operation, it has evolved into a redirection scam using the VexTrio and LosPollos affiliate networks. Hackers have found a new disguise for malware—virtual hard disk files. Threat actors are distributing VenomRAT through phishing emails with .VHD files masked as purchase orders. These files help the malware evade detection while a hidden batch script self-replicates, maintains PowerShell persistence, and steals data using HVNC and Pastebin-based C2 communication. Meanwhile, a year-old sophisticated phishing campaign has shifted gears. After successfully tricking Windows users with fake Microsoft security alerts on windows[.]net, attackers are now targeting macOS users. For detailed Cyber Threat Intel, click ‘Read More’.

A new ransomware strain isn’t just locking up files, it’s locking out hope of recovery. Researchers uncovered EByte Ransomware, a Golang-based malware that’s actively targeting Windows systems with advanced cryptographic techniques, making decryption nearly impossible without the attackers' key. A simple-looking PDF is all it takes for attackers to hijack your system. A new malware strain, Phantom Goblin, is being spread through RAR attachments in phishing campaigns, tricking users into opening a malicious LNK file disguised as a document. It also abuses VSCode tunnels for remote access. Attackers don’t need new tricks when unpatched systems do the job for them. The CISA has flagged five new vulnerabilities under active exploitation, affecting Advantive VeraCore and Ivanti Endpoint Manager. The VeraCore flaw exploitation is linked to a likely Vietnamese threat group, while the Ivanti EPM vulnerabilities allow attackers to coerce credentials for further access.
