The month of November 2023 saw a significant increase in ransomware attacks, with criminal groups taking advantage of the holiday season and companies with limited IT staff and cybersecurity solutions being particularly vulnerable. According to a report from Corvus Insurance, there was a 39.08% rise in new victims compared to the previous month and a staggering 100% increase compared to the same period last year, highlighting the growing threat of ransomware attacks.
Throughout the year, various ransomware variants such as LockBit, Clop, Play, BlackCat (ALHPV), and Akira remained highly active. One of the most prominent variants alone managed to amass $393 million from its victims, emphasizing the lucrative nature of these cyber crimes.
The success of ransomware-spreading gangs raises concerns about the factors contributing to their effectiveness. Many companies wrongly assume that only large firms are at risk and underestimate the likelihood of being targeted. However, hackers have become increasingly sophisticated and innovative in their approaches, with 73% of attacks proving financially rewarding for them.
These criminals employ double or triple extortion tactics to ensure financial gains. They may threaten victims and coerce them into paying the ransom or sell stolen data on the dark web for profit. Valuable information such as bank credentials, email IDs, call records, contact numbers, and social security numbers can be used by cyber crooks to construct detailed online user profiles.
To mitigate the risk of falling victim to ransomware attacks, individuals and organizations must exercise caution when sharing sensitive information online. Vigilance against phishing and other social engineering attacks is crucial. Importantly, it is advised never to pay a ransom to criminal gangs, as there is no guarantee of receiving a decryption key, and the fate of the stolen information on their servers remains uncertain.
