Read More Throughout 2023, Sekoia.io’s Threat Detection & Research (TDR) team actively tracked and monitored adversary C2 infrastructures set up and used by lucrative and state-sponsored intrusion sets to carry out malicious cyber activities.
Our analysts identified more than 85,000 IP addresses used as C2 servers in 2023, an increase of more than 30% compared to 2022.…
The cybersecurity landscape is in a state of flux, marked by flow of illicit activities within hacker forums. Not so recent events surrounding the shutdown and subsequent revival of Breach Forums have brought forth a wave of speculation, with some viewing it as an FBI HoneyPot, while others see it as an opportune space for continued illegal pursuits.…
ESET researchers have identified twelve Android espionage apps that share the same malicious code: six were available on Google Play, and six were found on VirusTotal. All the observed applications were advertised as messaging tools apart from one that posed as a news app. In the background, these apps covertly execute remote access trojan (RAT) code called VajraSpy, used for targeted espionage by the Patchwork APT group.…
Mandiant Managed Defense has been tracking UNC4990, an actor who heavily uses USB devices for initial infection. UNC4990 primarily targets users based in Italy and is likely motivated by financial gain. Our research shows this campaign has been ongoing since at least 2020.
Despite relying on the age-old tactic of weaponizing USB drives, UNC4990 continues to evolve their tools, tactics and procedures (TTPs).…
ESET has collaborated with the Federal Police of Brazil in an attempt to disrupt the Grandoreiro botnet. ESET contributed to the project by providing technical analysis, statistical information, and known command and control (C&C) server domain names and IP addresses.

On 2023-12-28, the Ukrainian government computer emergency and incident response team (CERT-UA) described a malicious espionage campaign that targeted government organizations in Ukraine. CERT-UA attributed the campaign to the APT28 threat-actor (aka Sofacy, Fancy Bear, etc.).
The malicious campaign leveraged spear-phishing to trick users into visiting a remote HTML page and opening a Windows shortcut, which in turn enabled the deployment of remote execution tools (MASEPIE, OCEANMAP), a credential stealer (STEELHOOK) as well as publicly available reconnaissance and credentials harvesting tool (Impacket).…
Key TakeawaysIn late December 2022, we observed threat actors exploiting a publicly exposed Remote Desktop Protocol (RDP) host, leading to data exfiltration and the deployment of Trigona ransomware.
On Christmas Eve, within just three hours of gaining initial access, the threat actors executed ransomware across the entire network.…
Read More [Update] January 30, 2024: “Official Attributions of Star Blizzard”
Within the continuously changing cyber threat landscape, the strategies of Star Blizzard unfold with a calculated precision, resembling a strategic orchestration. Spear-phishing, in this context, mirrors a carefully planned and executed maneuver.
