What’s the Cicada ransomware?
Cicada (often known as Cicada3301) is subtle ransomware written in Rust that has claimed greater than 20 victims since its discovery in June 2024.
Why is the ransomware known 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 very smart people.
In fact, there is no such thing as a purpose to imagine that the ransomware is in any trend associated to the enigmatic puzzles that appeared a decade earlier than it – aside from by way of the identify.
Truthful sufficient. What kind of corporations are being hit by Cicada?
In line with a weblog submit by safety researchers at Morphisec, at the least 21 corporations, predominantly in North America and the UK, have been hit by Cicada since June 18, 2024.
A lot 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 necessary knowledge and that recordsdata on the corporate’s community have been encrypted.
An additional message says that the gang is ready to supply “proof that the info has been stolen” and can delete all of the stolen info and “aid you rebuild your infrastructure and forestall related assaults sooner or later” if a cryptocurrency cost is made.
And I assume they are going to publish the info when you do not pay up?
Sure, the Cicada gang says that if a ransom just isn’t paid in time, then the stolen knowledge will probably be revealed on its weblog. However in addition they say that the info will probably be despatched “to all regulatory authorities in your nation, in addition to to your clients, companions, and opponents.”
That is a nasty risk. 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 also be written in Rust.
Whereas there isn’t any definitive proof, the similarities between Cicada and BlackCat, together with the usage of Rusy, evasion methods, and timing, recommend a attainable connection.
You have talked about Rust just a few instances. What’s that?
Rust is a programming language that has grow to be well-liked with ransomware builders lately. Particularly, 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 believed the authorities had taken motion to disrupt the ALPHV BlackCat ransomware?
Effectively 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.
Nonetheless, that victory was short-lived. ALPHV BlackCat re-emerged, threatened retaliation towards nations that assisted with the takedown, and explicitly warned that it will assault hospitals in future.
They do not sound like a pleasant bunch.
That is placing it mildly.
What can I do to scale back the chance of Cicada and different ransomware threats attacking my organisation?
- Preserve your safety software program up to date.
- Educate your workers about phishing emails and different social engineering methods.
- Implement strong backup and restoration procedures.
- Monitor your setting for suspicious exercise.
- Take into account using risk looking companies to proactively establish and mitigate threats.
Different greatest practices embrace creating robust, distinctive passwords, and preserving software program present. It’s also suggested to report ransomware assaults to CISA, a neighborhood FBI discipline workplace or a Secret Service discipline workplace.
