The weeks in review

Weekly review 41

19.10.2021 -The number of reports was very high last week. This was due, among other things, to a spate of spam advertising bitcoin investments and over a hundred reports of text messages with an alleged voicemail that led to Android malware. Another topic for the NCSC last week was a new scam involving online review systems.

Weekly review 40

12.10.2021 - Last week, the number of reports received remained moderate. The data leak from a hacked video streaming portal showed once again how quickly sensitive data can be made freely accessible on the internet. The second case is an example of how easy it is for fraudsters to obtain money using payment services.

Week 39 in review

05.10.2021 - With the start of the autumn holidays, the NCSC received fewer reports last week. It has observed that fake support call fraudsters have been trying to reach their victims in other ways recently. Ill-gotten money has to be laundered at some stage. The second case describes how people are sought for this.

Week 38 in review

27.09.2021 - The NCSC once again received an increased number of reports last week. Fraudulent competitions that claimed to mark the Coop's 50 anniversary were noteworthy. With classified ad scams where the victim is supposed to pay despite selling an item, the fraudsters go to considerable lengths to persuade the victims to hand over their credit card details.

Week 37 in review

21.09.2021 - The NCSC received an increased number of reports last week. Several variants of supposed threats on behalf of the police, among others, stood out. The emails threaten to initiate criminal proceedings against the recipient if no reply is received within 72 hours. Once again, a website promises victims of investment fraud that it will recover their lost money.

Week 36 in review

14.09.2021 - Last week, in addition to the reports it received (which were within the normal range), the NCSC's focus was on a new development. With immediate effect, the NCSC's weekly statistics on the number and type of reports are available in interactive form, thereby simplifying data queries. Among the reports, the NCSC noted another report about a fictitious hotel website, which was ostensibly looking for new staff but then demanded a "fee".

Week 35 in review

07.09.2021 - The NCSC registered an average number of reports last week. It dealt with reports about the resurrection of websites that were thought to have been deleted. There were also renewed reports of a familiar blackmail technique involving deleted databases.

Week 34 in review

31.08.2021 - The number of reports received by the NCSC increased again last week. There are still many reports concerning fake PostFinance pages opened via Google ads. The procedure is reminiscent of fake support calls. In addition, the victims of CEO fraud are being contacted not only via email, but also by phone. And it has become apparent that it is sometimes difficult for employees to recognise phishing emails with Office 365.

Week 33 in review

24.08.2021 - The NCSC received a moderate number of reports last week. Fraudsters attempted to lure visitors into making large "investments" with a supposed "promotion" for the cryptocurrency Cardano. Reports of ransomware incidents rose slightly again, with five reports. In addition, the NCSC received several reports about Instagram and Telegram accounts offering vaccination passports and COVID-19 certificates.

Week 32 in review

17.08.2021 - The NCSC received few reports last week. Fraudsters used a fake Google ad to try to lure bank customers to a bogus site. In another case, considerable effort was made to hack a Facebook account. In addition, an increasing number of attempted attacks on Synology network storage devices were reported in Switzerland and around the world. Users are strongly advised to use strong passwords

Week 31 in review

10.08.2021 - The NCSC once again received an average number of reports last week. A report on a cloned website revealed a new modus operandi in which the customer behaviour of Swiss companies is analysed. Moreover, further attempts were made to convince victims to install malware by phoning about alleged parcel deliveries. To do this, the attackers pretended to be from Swiss Post and did not use fictitious company names like in the past.

Week 30 in review

03.08.2021 - The number of reports received by the NCSC remained moderate last week. Fake reviews on well-known review sites give victims of investment scams tips and contact details for getting their money back. If victims act on these tips, they are scammed a second time. In addition, fraudsters have been trying to take over other people's WhatsApp accounts by means of voicemail hacking.

Week 29 in review

27.07.2021 - The NCSC received few reports last week. DDoS attacks by the Fancy Lazarus group continue to be reported. However, the second attack that had been threatened has yet to be observed. A perfidious approach to classified ad fraud led to losses for one victim. Fraudsters' attempts to lure people into dubious investment offers are becoming more and more sophisticated.

Week 28 in review

20.07.2021 - The number of reports received by the NCSC remains at a moderate level. This week saw several DDoS attacks reported to the NCSC. In addition, the NCSC received reports of an attempted text message scam on Facebook.

Week 27 in review

13.07.2021 - The number of reports received by the NCSC fell slightly last week. In two cases, different approaches were used to try to persuade victims to download malware. In order to prevent the software from being analysed, these files can often be downloaded only once.
