The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a now-patched security flaw impacting Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) software to its Known Exploited Vulnerabilities (KEV) catalog, following reports that it’s being likely exploited in Akira ransomware attacks.
The vulnerability in question is CVE-2020-3259 (CVSS score: 7.5), a high-severity information disclosure issue that could allow an attacker to retrieve memory contents on an affected device. It was patched by Cisco as part of updates released in May 2020.
According to Palo Alto Networks Unit 42, Akira is one of the 25 groups with newly established data leak sites in 2023, with the ransomware group publicly claiming nearly 200 victims. First observed in March 2023, the group is believed to share connections with the notorious Conti syndicate based on the fact that the ransom proceeds have been routed to Conti-affiliated wallet addresses.
In the fourth quarter of 2023 alone, the e-crime group listed 49 victims on its data leak portal, putting it behind LockBit (275), Play (110), ALPHV/BlackCat (102), NoEscape (76), 8Base (75), and Black Basta (72).
CVE-2020-3259 is far from the only flaw to be exploited for delivering ransomware. Earlier this month, Arctic Wolf Labs revealed the abuse of CVE-2023-22527 – a recently uncovered shortcoming in Atlassian Confluence Data Center and Confluence Server – to deploy C3RB3R ransomware, as well as cryptocurrency miners and remote access trojans.
There are indications that Alpha could be connected to NetWalker, which shuttered in January 2021 following an international law enforcement operation. The links pertain to overlaps in the source code and the tactics, techniques, and procedures (TTPs) used in attacks.
