How Weak Passwords Lead to Ransomware Attacks

Weak passwords can lead to ransomware attacks because they can be easily compromised through password-cracking techniques, allowing cybercriminals to gain access to an organization’s network where they can then inject ransomware. Often, when people think of the causes of ransomware infections, their first thought is it was caused by a phishing email.

The Anatomy of an ALPHA SPIDER Ransomware Attack

Over the last two years, CrowdStrike Services has run several incident response (IR) engagements — in both pre- and post-ransomware situations — in which different ALPHA SPIDER affiliates demonstrated novel offensive techniques coupled with more commonly observed techniques.

Game-Changer: Biometric-Stealing Malware

I have been working in cybersecurity for a long time, since 1987, over 35 years. And, surprisingly to many readers/observers, I often say I have not seen anything new in the hacker/malware space since I began. The same threats that were a problem then are the same problems now. Social engineering and unpatched software (and firmware) have long been the two biggest initial root causes for hacking…for decades.

New Research: Ransomware Incidents Spike 84% in 2023

The Billion Dollar Cost of Cybercrime: Lessons from the LockBit Takedown

The recent LockBit group take down has shown the world at large the cost of cybercrime. Initially it was reported that just over $100 million had been gathered through the nefarious acts of this particular group but, as I suspected, that initial figure was just a drop in the ocean. It turns out that the real figure was in excess of $1 billion dollars over the last four years, and I still suspect this may be more.

Only 7% of Organizations Can Restore Data Processes within 1-3 Days After a Ransomware Attack

New data on how organizations are able to respond to ransomware attacks also shows that paying a ransom is highly likely, despite having a policy of “Do Not Pay.” New research from security vendor Cohesity says organizations are overconfident in their ability to recover from a ransomware attack.
