TLDR InfoSec

FRAUDSTER STOLE OVER $1.5 MILLION FROM CITY OF BALTIMORE

A fraudster stole $1.5 million from Baltimore between February and March by pretending to be a vendor employee, hacking into the vendor's Workday account, and convincing AP staff to redirect bank details. The city recovered $721,000, but cannot recover $803,000 despite insurance claims and reissued payments. This is Baltimore's third instance of vendor fraud since 2019, highlighting ongoing weaknesses in financial controls following losses of $62,000 in 2019 and $376,000 in 2022.

THE RESURGENCE OF IOT MALWARE: INSIDE THE MIRAI-BASED BOTNET CAMPAIGN

The Gayfemboy botnet exploits vulnerabilities in DrayTek, TP-Link, Raisecom, and Cisco devices to deploy a Mirai-variant that uses modified UPX packing, custom architecture naming schemes, and hardcoded process termination lists to eliminate competing malware infections. The malware implements sophisticated evasion techniques, including 50-nanosecond sandbox delays, utilizes public DNS servers (1.1.1.1, 8.8.8.8) to bypass local filtering, and scans 15 predefined ports for C2 communication with domains such as cross-compiling[.]org and i-kiss-boys[.]com. Organizations should implement network monitoring for unusual DNS queries to public resolvers, deploy IPS signatures for the listed CVEs, and monitor for processes attempting to bind to UDP port 47272 or exhibiting the malware's distinctive process termination behavior.

START ACCELERATING SECURE APPLICATION DEVELOPMENT

Cortex Cloud ASPM is a prevention-first application security module that integrates with AppSec tools, such as Snyk, GitLab, and Checkmarx, to block vulnerabilities before they reach production. The platform offers automated remediation, inline IDE fixes, and correlates findings across code, cloud, and runtime to prioritize risks over false alarms. In early access, with general availability in H2 2025, it claims to be 10 times faster and more cost-effective than traditional reactive security.

SCARCRUFT USES ROKRAT MALWARE IN OPERATION HANKOOK PHANTOM TARGETING SOUTH KOREAN ACADEMICS

North Korean APT37 (ScarCruft) carried out Operation HanKook Phantom using spear-phishing emails with malicious LNK files disguised as PDFs to deliver RokRAT malware to South Korean research targets. The attack utilized fake newsletter lures from the National Intelligence Research Association, employing PowerShell scripts and fileless techniques to exfiltrate data via Dropbox, Google Cloud, and Yandex. This campaign shows APT37's focus on espionage against the South Korean government, research, and academic targets.

WHISTLEBLOWER SAYS TRUMP OFFICIALS COPIED MILLIONS OF SOCIAL SECURITY NUMBERS

A whistleblower at the Social Security Administration (SSA) stated that a former senior DOGE official, now at the SSA, copied the Social Security Numbers (SSNs), names, and dates of birth of over 300 million Americans to a private section of the agency's AWS cloud environment. The complaint states that the cloud environment was set up for DOGE-affiliated Social Security staffers but lacks independent security, monitoring, and oversight. The complaint also alleges that cybersecurity officials within the SSA described the decision to copy the data as “very high risk” and discussed the possibility of having to reissue SSNs in the event of a breach.
