Emerging Threats and Research
Phishing Attacks That Use SaaS Platforms Skyrocket 1,100%
A new Palo Alto Networks Unit 42 report reveals a sharp increase in phishing attacks that abuse software-as-a service platforms, like website builders and form builders. From June 2021 to June 2022, attacks have increased 1,100%. These phishing attacks sometimes impersonate legitimate sites to steal login credentials. Email users should be cautious of messages that request urgent action or make bold claims. Avoid clicking on any links or buttons in these emails and instead use a search engine to look up the official website.
French Hospital Faces a $10 Million Ransomware Attack
The Center Hospitalier Sud Francilien, which serves an area of 600,000 people and is located near Paris’s city center, was hit with a cyberattack on Sunday, August 21. The bad actors demanded a $10 million ransom in exchange for the decryption key to unlock medical imaging systems, information systems associated with patient admissions and other IT systems. While these vital technologies have been inaccessible the hospital has been referring patients to other medical centers.

DDoS Attacks Surge 203% The First Half of 2022
A recent Radware report revealed that malicious DDoS attacks grew by 203% in the first half of 2022, compared to the same six month period in 2021. In fact, DDoS attacks are already 60% higher for 2022 than they were for the entire year of 2021. What’s the cause? The report seems to emphasize that Russia’s invasion of Ukraine has altered the threat landscape, shifting it from pandemic-driven cybercrime to patriotic hacktivism and cyber war.
