What is common between Okta, Uber, and EA Games? All fell victim to cyberattacks enabled by a single access point: compromised employee credentials. In the ever-changing cybercrime landscape, cybercriminals always find ways to put their hands on corporate sensitive data. One of the most popular ways to gather such credentials is using information-stealing malware or simply buying the bots (machines already compromised by info-stealing malware) on botnet markets and Telegram channels.
Recently CISA reported that more than half of all cyberattacks on government entities and critical infrastructure involve valid credentials. That means that cybercriminals are using active employee credentials or default administrator credentials for their attacks. After acquiring login credentials, whether through purchase or by obtaining them for free, threat actors utilize these valuable assets in various campaigns, ranging from phishing to ransomware attacks.
In this blog post, KELA examines the contrast between two methods of acquiring credentials: botnet markets such as Russian Market, Genesis, and TwoEasy (enabling the individual purchase of bots), and “clouds of logs”. Clouds of logs operate on a subscription basis, allowing threat actors to purchase and utilize multiple bots together through platforms like Telegram. The user-friendly Telegram interface, extensive bot sharing, and diverse actors and information-stealing tools collectively enhance the appeal and convenience of this messaging platform for conducting such transactions.
