FBI Announces That Hacktivist DDoS Attacks Can Have Minimal Impact
As Russian military attacks on Ukraine continue, hacktivists are using DDoS attacks to target critical infrastructure companies. The FBI has released a notification emphasizing that these attacks can have minimal impact with the right mitigations.

Malicious Trojan Allows Cybercriminals to Hijack Google Chrome
Google Chrome is in the news again this week. This time for a malicious extension named Cloud9, which acts as a remote access trojan (RAT), enabling a cybercriminal to remotely execute commands and control the browser. Once Google Chrome becomes infected, a threat actor can steal online accounts, log keystrokes and enlist the browser in DDoS attacks. The malicious extension isn’t on the official Chrome web store, but is instead being circulated via other means, such as fake Adobe Flash Player updates.
Emerging Threats and Research
Banking Trojan Gets 100,000+ Downloads on Google Play
The Android banking trojan Vultur has been running rampant in the Google Play Store, racking up more than 100,000 downloads. According to cybersecurity company Cleafy, threat actors choose official app stores to deliver malware because the platforms provide greater visibility and therefore a higher chance to defraud victims. As for how the malware impacts users, Cleafy said, “Once the banking trojan (Vultur) has been downloaded and installed through a fake update, threat actors can observe everything that happens on the infected devices and carry out bank fraud through account takeover attacks.”
