What’s the Cicada ransomware?
Cicada (also called Cicada3301) is refined ransomware written in Rust that has claimed greater than 20 victims since its discovery in June 2024.
Why is the ransomware referred to as Cicada?
The criminals behind Cicada seem to have named it after the mysterious Cicada 3301 puzzles posted on the web between 2012 and 2014, seemingly to recruit extremely smart people.
In fact, there isn’t any purpose to consider that the ransomware is in any style associated to the enigmatic puzzles that appeared a decade earlier than it – apart from by means of the title.
Honest sufficient. What kind of firms are being hit by Cicada?
In accordance with a weblog submit by safety researchers at Morphisec, at the least 21 firms, predominantly in North America and the UK, have been hit by Cicada since June 18, 2024.
Many of the organisations affected have been small and mid-sized companies (18), with the remaining three described as enterprises. Victims have been famous in quite a lot of business sectors, together with manufacturing/industrial, healthcare, retail, and hospitality.
Organizations hit by the Cicada ransomware are greeted by a message telling them that attackers have downloaded their essential knowledge and that information on the corporate’s community have been encrypted.
An additional message says that the gang is ready to offer “proof that the information has been stolen” and can delete all of the stolen data and “assist you rebuild your infrastructure and forestall comparable assaults sooner or later” if a cryptocurrency fee is made.
And I assume they are going to publish the information in case you do not pay up?
Sure, the Cicada gang says that if a ransom shouldn’t be paid in time, then the stolen knowledge shall be revealed on its weblog. However additionally they say that the information shall be despatched “to all regulatory authorities in your nation, in addition to to your prospects, companions, and opponents.”
That is a nasty menace. Do we all know who’s behind Cicada?
Though we have no idea the identities of these accountable, safety researchers say that there are putting similarities between Cicada and the ALPHV BlackCat ALPHV ransomware – which can be written in Rust.
Whereas there isn’t any definitive proof, the similarities between Cicada and BlackCat, together with using Rusy, evasion methods, and timing, counsel a attainable connection.
You’ve got talked about Rust a number of instances. What’s that?
Rust is a programming language that has develop into standard with ransomware builders lately. Specifically, ransomware teams like BlackCat and Hive have used Rust to create strains of their malware – partially as a result of it makes reverse-engineering extra tough and because of the difficulties some malware detection methods have in reliably detecting Rust-based ransomware through static evaluation.
I assumed the authorities had taken motion to disrupt the ALPHV BlackCat ransomware?
Properly remembered. In December 2013, the US Division of Justice introduced it had disrupted the ransomware gang’s operations and seized decryption keys to assist victims unlock their knowledge with out paying a ransom.
Nevertheless, that victory was short-lived. ALPHV BlackCat re-emerged, threatened retaliation towards nations that assisted with the takedown, and explicitly warned that it might assault hospitals in future.
They do not sound like a pleasant bunch.
That is placing it mildly.
