Nov 23, 2022
As many as 34 Russian-speaking gangs distributing information-stealing malware under the stealer-as-a-service model stole no fewer than 50 million passwords in the first seven months of 2022. "The underground market value of stolen logs and compromised card details is estimated around $5.8 million," Singapore-headquartered Group-IB  said  in a report shared with The Hacker News. Aside from looting passwords, the stealers also harvested 2.11 billion cookie files, 113,204 crypto wallets, and 103,150 payment cards. A majority of the victims were located in the U.S., followed by Brazil, India, Germany, Indonesia, the Philippines, France, Turkey, Vietnam, and Italy. In total, over 890,000 devices in 111 countries were infected during the time frame. Group-IB said the members of several scam groups who are propagating the information stealers previously participated in the  Classiscam  operation.

A French-speaking threat actor dubbed  OPERA1ER  has been linked to a series of more than 30 successful cyber attacks aimed at banks, financial services, and telecom companies across Africa, Asia, and Latin America between 2018 and 2022. According to Singapore-headquartered cybersecurity company Group-IB, the attacks have led to thefts totaling $11 million, with actual damages estimated to be as high as $30 million. Some of the more recent attacks in 2021 and 2021 have singled out five different banks in Burkina Faso, Benin, Ivory Coast, and Senegal. Many of the victims identified are said to have been compromised twice, and their infrastructure subsequently weaponized to strike other organizations. OPERA1ER, also called by the names DESKTOP-GROUP, Common Raven, and NXSMS, is known to be active since 2016, operating with the goal of conducting financially motivated heists and exfiltration of documents for further use in spear-phishing attacks. "OPERA1ER often operates during
Hackers Actively Exploiting Cisco AnyConnect and GIGABYTE Drivers Vulnerabilities

Hackers Actively Exploiting Cisco AnyConnect and GIGABYTE Drivers Vulnerabilities

Oct 26, 2022
Cisco has warned of active exploitation attempts targeting a pair of two-year-old security flaws in the Cisco AnyConnect Secure Mobility Client for Windows. Tracked as  CVE-2020-3153  (CVSS score: 6.5) and  CVE-2020-3433  (CVSS score: 7.8), the vulnerabilities could enable local authenticated attackers to perform DLL hijacking and copy arbitrary files to system directories with elevated privileges.  While CVE-2020-3153 was addressed by Cisco in February 2020, a fix for CVE-2020-3433 was shipped in August 2020. "In October 2022, the Cisco Product Security Incident Response Team became aware of additional attempted exploitation of this vulnerability in the wild," the networking equipment maker said in an updated advisory. "Cisco continues to strongly recommend that customers upgrade to a fixed software release to remediate this vulnerability." The alert comes as the U.S. Cybersecurity and Infrastructure Security Agency (CISA) moved to add the two flaws to its K
Cybercriminals Used Two PoS Malware to Steal Details of Over 167,000 Credit Cards

Cybercriminals Used Two PoS Malware to Steal Details of Over 167,000 Credit Cards

Oct 25, 2022
Two point-of-sale (PoS) malware variants have been put to use by a threat actor to steal information related to more than 167,000 credit cards from payment terminals. According to Singapore-headquartered cybersecurity company Group-IB, the stolen data dumps could net the operators as much as $3.34 million by selling them on underground forums. While a significant proportion of attacks aimed at gathering payment data rely on  JavaScript sniffers  (aka web skimmers) stealthily inserted on e-commerce websites, PoS malware continues to be an ongoing, if less popular, threat. Just last month, Kaspersky detailed new tactics adopted by a Brazilian threat actor known as  Prilex  to steal money by means of fraudulent transactions. "Almost all PoS malware strains have a similar card dump extraction functionality, but different methods for maintaining persistence on infected devices, data exfiltration and processing," researchers Nikolay Shelekhov and Said Khamchiev  said .

OldGremlin Ransomware Targeted Over a Dozen Russian Entities in Multi-Million Scheme

Oct 20, 2022
A Russian-speaking ransomware group dubbed OldGremlin has been attributed to 16 malicious campaigns aimed at entities operating in the transcontinental Eurasian nation over the course of two and a half years. "The group's victims include companies in sectors such as logistics, industry, insurance, retail, real estate, software development, and banking," Group-IB  said  in an exhaustive report shared with The Hacker News. "In 2020, the group even targeted an arms manufacturer." In what's a rarity in the ransomware landscape, OldGremlin (aka TinyScouts) is one of the very few financially motivated cybercrime gangs that primarily focuses on Russian companies. Other notable groups consist of Dharma, Crylock, and Thanos, contributing to an uptick in ransomware attacks targeting businesses in the country by over 200% in 2021. OldGremlin first came to light in September 2020 when the Singapore-headquartered cybersecurity company  disclosed  nine campaigns orch

Okta Hackers Behind Twilio and Cloudflare Attacks Hit Over 130 Organizations

Aug 25, 2022
The threat actor behind the attacks on  Twilio  and  Cloudflare  earlier this month has been linked to a broader phishing campaign aimed at 136 organizations that resulted in a cumulative compromise of 9,931 accounts. The activity has been condemned  0ktapus  by Group-IB because the initial goal of the attacks was to "obtain Okta identity credentials and two-factor authentication (2FA) codes from users of the targeted organizations." Calling the attacks well designed and executed, the Singapore-headquartered company said the adversary singled out employees of companies that are customers of identity services provider Okta. The modus operandi involved sending targets text messages containing links to phishing sites that impersonated the Okta authentication page of the respective targeted entities. "This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations," Group-IB  said . "Furthe

The capillary diffusion of mobile devices, the lack of security systems on these platforms and low level of awareness on principal cyber threats made them a privileged target for cybercrime. We have assisted in the recent year to an explosion of malware designed to hit principal mobile OSs, in a recent report Sophos security firm revealed that in Australia and the U.S. Android threat exposure rates exceeding those of PCs showing the urgency to implement proper countermeasures. The situation appears really critical that why I asked to the expert of Group-IB Forensics Lab to show me how these agents work with a really case study. Several month ago Group-IB Forensics Lab detected mobile-banking malware through Google Play by Sberbank request (Russian leading national bank).  The File associated to the malware was named sber.apk , it was an Android Package having size of 225,905 bytes and digest md5: F27D43DFEEDFFAC2EC7E4A069B3C9516 .
