Cyber Security Steps To Protect Your Company

Ransomware attacks rose again. The number of ransomware families rose from 143 to 157 in just one year. This means that the frequency and severity of attacks is still increasing. Ransomware attacks are up over last quarter, over the previous year, and up over the last three years.

The cybersecurity report you just read found that these cybercriminal groups are continuing to target unpatched vulnerabilities and weaponize zero-day vulnerabilities in record time to instigate crippling attacks. At the same time, they are broadening their spheres of attack and finding newer ways to compromise organizational networks and fearlessly trigger high-impact assaults.

Ransomware attacks can be devastating. According to Coveware, an attack costs an average of $220,298 and 23 days of downtime. Given the scramble to shift to the digital landscape combined with unprecedented shortages of skilled IT labor, a cyber-attack could cripple even the strongest businesses.

OpenSSL Infinite Loop Vulnerability

The US National Security Agency (NSA) officials have recently discovered a vulnerability in the OpenSSL cryptographic library. This vulnerability can be used to conduct denial-of-service attacks and can be easily weaponized by its potential attackers.

OpenSSL is a popular cryptography library used to encrypt data and verify digital signatures. The bug affects the BN_mod_sqrt() function, which is used to calculate the modular square root and parses certificates that use elliptic curve public key encryption. This vulnerability has been given the identifier CVE-2022-0778.

If an attacker submits a certificate with broken curve parameters, the program will go into an infinite loop and crash. This will cause denial of service.

“Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack,” OpenSSL said in a March 15 security advisory. “The infinite loop
