Fog, Akira ransomware teams exploit crucial Veeam backup flaw – Cyber Tech

The Fog and Akira ransomware gangs have been noticed exploiting a crucial vulnerability that lets them run a distant code execution (RCE) on Veeam Backup and Replications servers.

Whereas Veeam disclosed this crucial deserialization bug and launched a patch for CVE-2024-40711 on Sept. 4, publication of the proof-of-concept (PoC) developed by watchTowr Labs was delayed till Sept. 15 to provide weak companies time to implement the mandatory updates.

“Sadly, this window of alternative proved to be inadequate for a lot of clients, as is commonly the case when vulnerabilities are disclosed,” defined Patrick Tiquet, vp, safety and structure at Keeper Safety.

In an Oct. 10 put up on X, Sophos X-Ops reported that in each circumstances involving Fog and Akira, the attackers initially accessed targets utilizing compromised VPN gateways with out multi-factor authentication (MFA) enabled. The researchers added that a few of these VPNs had been operating unsupported software program variations, making them much more weak.

Tiquet identified that enabling MFA provides a crucial layer of safety. Even when a password will get compromised, Tiquet stated an attacker can not simply acquire entry with out the second authentication issue, lowering the chance of profitable assaults by means of stolen credentials.

“Implementing a password supervisor also can strengthen this protection by creating, storing and routinely filling high-strength random passwords for varied accounts,” stated Tiquet. “Password managers additionally help strong MFA choices, making it considerably tougher for unhealthy actors to realize unauthorized entry.”

Jason Soroko, senior fellow at Sectigo, stated it’s frequent for organizations to delay patching to allow them to check the patch or work it into the timing of their upkeep home windows. Nevertheless, this provides the attackers a window to assault.

“Attackers can typically reverse engineer patches after which create tailor-made malware to take advantage of the vulnerability that was patched,” defined Soroko. “This highlights the necessity to patch rapidly no matter whether or not white hat researchers launch exploit code.”

The Fog ransomware group launched in Could 2024 targeted on attacking U.S. academic establishments. Akira began in March 2023 and has primarily focused organizations primarily based in Europe, North America, and Australia working within the authorities, manufacturing, expertise, schooling, consulting, prescription drugs, and telecom sectors.
