Law enforcement success inevitably sparks criminals to become more innovative, including shifting from centralized markets - such as Hansa and Wall Street Market - to encrypted and distributed marketplaces, says the University of Surrey's Alan Woodward.
Online attack threats continue to intensify, with criminals preferring ransomware, DDoS attacks and business email compromises, warns Europol, the EU's law enforcement intelligence agency. After numerous successful disruptions by police, criminals have responded by launching increasingly complex attacks.
Rather than focusing solely on rankings offered by the common vulnerability scoring system, or CVSS, when setting priorities for risk mitigation, organizations need to size up the specific potential risks that vulnerabilities pose to their critical assets, according to a new report from RiskSense.
More than 600 ransomware attacks pummelled local governments, schools districts and healthcare providers across the U.S. in the first three quarters of this year, according to a study by security firm Emsisoft. Meanwhile, the FBI this week issued a fresh warning about the threat.
The latest edition of the ISMG Security Report analyzes concerns about the use of Huawei equipment by U.S. telecommunications firms. Also featured: A Huawei executive discusses 5G security, plus an update on an Australian ransomware attack.
The city of Baltimore's ransomware outbreak - $18 million in costs and counting - led to many crypto-locked files being lost forever, because no IT policy mandated centralized file backups. But effective IT solutions exist to help solve this challenge, provided they're deployed in advance of an attack.
Did the gang behind GandCrab fake its retirement? Security experts say there's mounting evidence that the operators of the notorious ransomware-as-a-service operation only announced their retirement after ramping up the rival Sodinokibi/REvil service.
A hacker group called Tortoiseshell has been hitting targets in the Middle East since at least July 2018, apparently targeting IT service providers to gain access to many potential targets at once. The campaign is fresh proof that criminals and nation-state attackers alike continue to favor supply chain attacks.
As part of the U.S. government's continuing efforts to highlight the North Korean government's cyberattacks, the U.S. Treasury Department has sanctioned three alleged North Korean hacking groups that have been blamed for the WannaCry ransomware, online bank heists and destructive malware attacks.
Ransomware-wielding attackers treat infecting endpoints as a business and put customer relationship management principles to work, says Bill Siegel, CEO of ransomware incident response firm Coveware. He notes criminals "go after the low-hanging fruit because it's cheap and the conversion rate is high."
Cybercrime is surging thanks, in part, to the availability of inexpensive hacking tools and services. A recent look by security firm Armour at black market offerings finds stolen payment card data, RDP credentials, ransomware and DDoS services are widely available for sale.
In the past year, cybercriminals behind two of the biggest ransomware attacks have abandoned other techniques in favor of exploiting remote desktop protocol. Matt Boddy of Sophos explains why RDP attacks are so popular - and what you can do to discourage them.
Three weeks after a ransomware attack slammed 22 Texas municipalities' systems, state officials say more than half of the cities have returned to normal operations and the rest have advanced to system restoration.
