Attackers, after an initial compromise, look to remain inside a network for as long as possible. For this, they use different methods. Beaconing is one of the common techniques used to maintain this access. Beaconing activity can easily blend into normal traffic and can remain unnoticed for long periods. Therefore, it is important for IT and security teams to understand how beaconing works in order to effectively carry out beaconing detection and response.

Account takeover prevention for credit unions has reached an inflection point. One concept underpins most modern failures: the timing gap, the period between a member engaging with a scam or impersonation interaction and the moment a security or fraud team becomes aware of risk. During this gap, access is often treated as legitimate even though compromise has already occurred.

The image of the cyber attacker is changing. For years, the industry focused on email gateways and typo-squatted domains like citi-bank-security.com. But according to Tzoor Cohen, CTI Lead at Memcyco, the battleground has shifted. In 2026, the most dangerous social engineering tactics typically don’t start in an inbox. They start on social media, utilize legitimate infrastructure like Bitly, and exploit the user interface (UI) of mobile devices to hide malicious intent.

Last week’s disclosure from AWS is another reminder that in the cloud, attackers don’t need to break in. They just need a working set of keys. Several AWS customers learned this the hard way when threat actors used compromised IAM credentials to deploy a rapid cryptomining campaign across EC2 and ECS environments. The incident didn’t rely on vulnerabilities or sophisticated exploitation. It relied on valid credentials and overly permissive access.

Eighty-one percent of small businesses suffered a security or data breach over the past year, and 38% of these businesses were forced to raise their prices as a result, a report from the Identity Theft Resource Center (ITRC) has found. The report notes that external hackers have overtaken malicious insiders as the most common root cause of these incidents. This trend is partially driven by AI-assisted social engineering attacks, which were cited as a root cause by more than 41% of victims.
